Spinach Soufflé has always held a special place in my heart, a treasured recipe passed down through generations. What began as my mom’s comforting concoction, famously featuring Velveeta, has evolved into a sophisticated yet equally delicious version made with sharp cheddar. This cheesy, vibrant casserole isn’t just a dish; it’s a beloved holiday tradition that graces our table year after year, bringing warmth and flavor to every celebration.
This delightful Spinach Casserole is an absolute must-have on our holiday menu, a versatile crowd-pleaser that fits perfectly into any festive spread. While it shines as a standalone vegetarian meal, offering a rich and satisfying option for those seeking plant-based goodness, its adaptability truly sets it apart. Imagine transforming it into a hearty entrée by adding leftover Easter ham, infusing it with a smoky depth that complements the creamy spinach and sharp cheddar beautifully. Whether served as a elegant side dish alongside a grand feast or as the star of a casual family dinner, this easy spinach recipe promises to be a memorable addition to your culinary repertoire.
Why This Cheesy Spinach Soufflé Belongs on Your Table
There are countless reasons why this particular spinach soufflé recipe has earned its place as a family favorite, cherished across generations. It’s more than just a dish; it’s a culinary legacy that continues to impress and satisfy, making it an essential addition to your recipe collection. Here’s why you absolutely need to try this easy and delicious spinach casserole:
- A Timeless Family Recipe with a Modern Twist: This super easy spinach soufflé is truly a treasured recipe from my childhood, conjuring warm memories with every bite. While my mom’s original version proudly featured a processed cheese spread (yes, Velveeta!), and I adored it, this recipe has been thoughtfully updated. Fast forward a few years, and I stumbled upon a similar recipe in our local Junior League cookbook, Winners, which inspired an upgrade to a lovely sharp cheddar. This evolution maintains the nostalgic comfort while elevating the flavor profile, making it a sophisticated yet approachable dish.
- Even Picky Eaters Will Love It: This might be the most surprising reason of all! My daughter, who famously avoids most vegetables, absolutely adores this spinach soufflé. In fact, spinach is practically the only vegetable Katie will willingly eat, and it was this very casserole that converted her. If a dish can win over a skeptical palate, you know it’s truly something special! Its creamy texture and rich cheesy flavor cleverly mask the spinach, making it an ideal way to introduce more greens to your family.
- The Cottage Cheese Secret: Don’t let the mention of cottage cheese deter you! Even if you typically shy away from it, you won’t even notice its presence in this recipe. When blended with the other ingredients, the cottage cheese melts into a wonderfully smooth consistency, adding an incredible creaminess and depth without any discernible texture or taste. It’s truly a secret ingredient that contributes to the soufflé’s luxurious mouthfeel without being a distraction.
- Effortless Preparation for Busy Lives: Despite its elegant presentation and rich flavor, this cheesy spinach casserole is remarkably simple to prepare. With minimal hands-on time and straightforward steps, it’s a fantastic option for busy weeknights or when you need a reliable dish for holiday gatherings. Most of the work involves mixing ingredients, allowing you more time to enjoy your company or tackle other kitchen tasks.
- Perfect for Any Occasion: Whether you’re hosting a grand holiday feast, a cozy family dinner, or looking for a comforting brunch item, this spinach soufflé fits the bill. Its versatility means it can be served as a hearty side, a light vegetarian main course, or even as part of a breakfast spread with added protein.
Essential Ingredients for Your Perfect Spinach Soufflé
Crafting this delightful spinach soufflé requires a few simple, high-quality ingredients that come together to create a rich, creamy, and satisfying dish. Here’s a closer look at what you’ll need and some tips for selecting the best components:
- Kitchen Staples: You’ll start with everyday pantry essentials like butter for richness, all-purpose flour to help bind the mixture and create a perfect texture, and a touch of salt to enhance all the flavors. These form the base of our savory soufflé.
- Eggs: You will need six large eggs for this recipe. Eggs are crucial for binding the ingredients together and giving the soufflé its characteristic fluffy, custardy texture. While this isn’t a traditional soufflé with whipped egg whites, the whole eggs still provide a wonderful structure. Ensure they are at room temperature for optimal mixing.
- Sharp Cheddar Cheese: An 8-ounce block of sharp cheddar cheese, cubed, is the star of the show. The sharpness of the cheddar provides a robust, tangy flavor that beautifully complements the spinach. Avoid pre-shredded cheese if possible, as it often contains anti-caking agents that can affect the melt and creaminess. Cubing it yourself ensures better flavor and a smoother melt.
- Cottage Cheese: Opt for small curd or “old-fashioned” cottage cheese, typically around 24 ounces. The smaller curds blend more seamlessly into the mixture, virtually disappearing into a creamy texture without leaving any chunky bits. This provides a delightful creaminess and moisture that is undetectable as cottage cheese but essential for the soufflé’s luxurious mouthfeel.
- Frozen, Chopped Spinach: You’ll need two 10-ounce packages of frozen, chopped spinach. The key here is to defrost it thoroughly and then squeeze it very, very dry. Excess water is the enemy of a good soufflé, making it watery and less flavorful. Defrosting overnight in the refrigerator is ideal, but for quicker results, you can use the microwave or let it sit on the counter for a few hours.
- Optional Ingredient, Ham: For a heartier, more substantial meal, consider adding 2 cups of chopped, cooked ham, especially delicious with leftover Easter ham. If you choose to include ham, be sure to reduce the added salt in the recipe, as ham can be quite salty on its own. This transforms the dish from a side to a delightful main course.
Effortless Steps to Your Perfect Cheesy Spinach Soufflé
Creating this delicious spinach soufflé is surprisingly straightforward, designed for ease without compromising on flavor. While it might not be a “soufflé” in the classical culinary sense—as the eggs are incorporated whole rather than separating and whipping the whites—it carries the cherished name from my mom’s original 1960s/70s recipe, and that’s good enough for us!
- Prepare the Spinach: This is a crucial first step for a perfectly textured casserole. Begin by defrosting two packages of frozen chopped spinach. The easiest method is to place them in the refrigerator overnight. If you’re short on time and the spinach is still a bit icy in the morning, let it sit on the counter for an hour or so to fully thaw.
- Squeeze, Squeeze, Squeeze! Once thawed, it’s absolutely vital to squeeze every last drop of excess water from the spinach. Any leftover moisture will result in a watery, unappetizing spinach casserole. My go-to method is to use my hands, taking handfuls of spinach and squeezing them firmly over the sink until no more liquid comes out. Some people prefer a potato ricer, though my husband (the dishwasher!) isn’t a fan of cleaning the tiny spinach bits from it. Alternatively, you can place the spinach in a clean kitchen towel or cheesecloth and twist tightly.
- Combine All Ingredients: In a large mixing bowl, whisk the six eggs until they are light and frothy. Then, add the thoroughly squeezed spinach, the small curd cottage cheese (look for “old-fashioned” for that extra creamy texture), the cubed sharp cheddar cheese, two tablespoons of all-purpose flour, two tablespoons of cubed butter, and a teaspoon of salt. Mix everything together until all ingredients are well combined and evenly distributed.
- Prepare for Baking: Preheat your oven to 350°F (175°C). Generously grease a 9×13 inch casserole dish, or a comparable oven-safe dish, to prevent sticking and ensure easy serving.
- Bake to Perfection: Pour the spinach mixture evenly into the prepared casserole dish. Place it in the preheated oven and bake for approximately 30-45 minutes. The baking time can vary slightly depending on your oven and the exact depth of your dish. You’ll know it’s ready when the center is set, the edges are lightly golden, and a knife inserted into the middle comes out clean.
- Adjust for Holiday Feasts: During holidays like Thanksgiving, when oven space is precious, I often slide this casserole into the oven alongside the turkey. If your oven is set to a temperature other than 350°F, simply adjust the baking time accordingly. For example, at a slightly lower temperature, it might need a bit longer, and at a higher temperature, it will bake faster.
- Optional Ham Addition: My oldest loves when I make this after Easter by adding chunks of leftover ham. If you’re adding about 2 cups of chopped ham, be sure to reduce the initial salt in the recipe, as the ham will contribute its own saltiness to the dish. This addition transforms the soufflé from a fantastic side dish into a substantial, flavorful entrée, making it perfect for brunch or a hearty dinner.
Delicious Variations to Elevate Your Spinach Soufflé
While the classic spinach soufflé is a beloved dish on its own, its simple base makes it incredibly versatile for creative culinary experimentation. Don’t hesitate to personalize this recipe with your favorite flavors and ingredients. Here are some fantastic variations to inspire you and keep your holiday spinach casserole fresh and exciting:
- A Gooey Cheese Topping: For an extra layer of indulgence, sprinkle an additional layer of your favorite cheese (cheddar, mozzarella, or a blend) over the top during the last 10-15 minutes of baking. This creates a beautifully golden, bubbly, and slightly gooey crust that’s always a welcome bonus and adds a lovely texture contrast.
- Explore Different Cheeses: While sharp cheddar offers a wonderfully robust flavor, feel free to experiment with other cheeses. Mozzarella will lend a milder, stretchier texture, while Monterey Jack provides a creamy, slightly buttery taste. A blend of Gruyere and Parmesan could also elevate the dish with a more gourmet touch.
- Amp Up the Flavor with Spices:
- A Touch of Heat: For those who enjoy a little kick, add a pinch or two of red pepper flakes to the mixture. This subtle warmth beautifully complements the richness of the cheese and spinach.
- Classic Nutmeg: Nutmeg is a classic pairing for spinach dishes, known for its warm, slightly sweet, and aromatic notes. A few grates of fresh nutmeg or a pinch or two of ground nutmeg will taste terrific. Remember, a little goes a long way, so don’t overdo it!
- Garlic and Onion Powder: For a deeper savory profile, a teaspoon of garlic powder and half a teaspoon of onion powder can be mixed in.
- Low-Carb Friendly Swaps: If you’re watching your carbohydrate intake, easily adapt this recipe by swapping out the all-purpose flour for an equal amount of almond flour. This simple substitution makes it a fantastic low-carb side or even a satisfying main course.
- Hearty Protein Additions:
- Ham Infusion: As mentioned, adding 2 cups of chopped, cooked ham (perfect for Easter leftovers!) and mixing it to combine creates a wonderfully savory and substantial dish. Remember to reduce or omit the added salt in the recipe since ham is already quite salty.
- Crispy Bacon: Cooked and crumbled bacon bits stirred into the mixture before baking will add an irresistible smoky, salty crunch.
- Sautéed Mushrooms: For an earthy vegetarian twist, sautéed mushrooms can be folded into the mixture.
- Fresh Herbs: Incorporate fresh chopped herbs like chives, parsley, or dill for a burst of fresh flavor. Add them just before baking for the best results.
Frequently Asked Questions About Spinach Soufflé
Absolutely! This spinach casserole is an excellent candidate for make-ahead preparation, which makes it perfect for busy holidays or entertaining. I often prepare it in the morning of the day I plan to serve it for dinner. Simply assemble the casserole in your baking dish, cover it tightly with plastic wrap, and store it in the refrigerator. When you’re ready to bake, pull it out of the refrigerator while you preheat the oven. Keep in mind that a cold casserole will need extra time to bake through and reach its optimal temperature compared to one freshly made at room temperature. Allow an additional 10-15 minutes, or until the center is fully set.
Like most baked dishes, leftovers of this cheesy spinach soufflé can be stored covered in the refrigerator for up to 3 days. Ensure it has not been left at room temperature for more than 2 hours to maintain food safety. For longer storage, this casserole freezes well. Simply transfer cooled leftovers to an airtight, freezer-safe container or wrap individual portions tightly in plastic wrap and then foil. It can be safely frozen for up to 3 months. To reheat, thaw overnight in the refrigerator and then bake at 350°F (175°C) until heated through, or reheat smaller portions in the microwave. Although Stouffer’s Spinach Soufflé is a frozen product, I haven’t personally tested freezing this exact homemade recipe, but the ingredients are generally freezer-friendly.
According to my trusty Food Lover’s Companion, a soufflé (pronounced soo-FLAY) “is a light, airy mixture that usually begins with a thick egg yolk-based sauce or puree that is lightened by stiffly beaten egg whites.” These whipped egg whites are carefully folded in just before baking, creating a delicate, airy texture that rises dramatically in the oven. Based on this traditional definition, our delightful cheesy spinach dish, while incredibly delicious and satisfying, may not officially be categorized as a true culinary soufflé since it uses whole eggs and doesn’t rely on the technique of folding in stiffly beaten egg whites for its rise. However, its classic name evokes comfort and tradition, and that’s what truly matters!
This versatile spinach soufflé pairs beautifully with a variety of main courses. It’s a classic accompaniment to roasted turkey or ham, making it a holiday staple. It also complements roasted chicken, grilled fish, or a juicy steak wonderfully. For a complete vegetarian meal, serve it alongside a crisp green salad, some crusty bread, or a simple roasted vegetable medley.
Yes, you can absolutely use fresh spinach! You’ll need about 1.5 to 2 pounds of fresh spinach to yield the equivalent of two 10-ounce packages of frozen, chopped spinach. Fresh spinach needs to be thoroughly washed, then wilted in a pan with a small amount of water or steamed. After wilting, it’s crucial to squeeze out all the excess moisture just as you would with frozen spinach. This step is key to preventing a watery casserole.

Adapted from “Winners,” a Junior League cookbook from Indianapolis.
For a heartier dish, you may add 2 cups of chopped, cooked ham. Remember to reduce or omit the salt if you do, as ham adds significant salinity. This variation is particularly delicious with leftover Easter ham.
To make ahead: Prepare the casserole, cover tightly, and refrigerate for up to 24 hours. Add an extra 10-15 minutes to baking time when baking from cold.
