Ingredients You’ll Need

The beauty of this Creamy Spinach and Cottage Cheese Casserole Recipe is how well these ingredients play off each other—simple, fresh, and perfectly balanced. When shopping, aim for fresh eggs and good-quality cottage cheese, and thaw and squeeze your spinach really well to avoid excess water.

  • Eggs: They bind everything together and add structure without heaviness.
  • Cottage Cheese: This is where the creaminess really shines; I prefer full-fat for best flavor and texture.
  • Frozen Chopped Spinach: Thaw it completely and squeeze out every last drop of moisture to keep the casserole from becoming watery.
  • Feta Cheese: Adds a tangy, salty punch that’s just irresistible.
  • Sweet Onion: Provides a subtle sweetness and depth; sautéing it first is optional but can mellow the flavor.
  • Butter (melted): Helps with richness and gives a lovely, smooth finish.
  • Parmesan Cheese: Adds a nutty, savory boost on top and inside the mixture.
  • Black Pepper: Just a touch to enhance the flavors.
  • Garlic Powder: Adds warmth without overpowering everything.

  • Sauteed Mushrooms: I sometimes add sautéed mushrooms for an earthy twist; it adds great texture too.

  • Spicy Kick: A pinch of red pepper flakes can add a subtle heat that my husband adores.
  • Vegan Version: Swap eggs for a flaxseed egg and use vegan cheese alternatives to make it dairy-free (though it won’t be quite as creamy, but still tasty!).

How to Make Creamy Spinach and Cottage Cheese Casserole Recipe

Step 1: Prep the Spinach Like a Pro

Start by thawing your frozen chopped spinach thoroughly. I like to microwave it for about 2 minutes, then place it in a clean kitchen towel and squeeze out as much water as possible—this step is crucial to avoid a soggy casserole. The drier the spinach, the better the final texture will be.

Step 2: Mix All Ingredients Together Gently

In a large bowl, beat three eggs until smooth. Add the cottage cheese, crumbled feta, diced sweet onion, melted butter, grated Parmesan, black pepper, garlic powder, and a dash of nutmeg. Then fold in that well-drained spinach. Don’t overmix—you want everything combined but still retaining some texture.

Step 3: Bake to Perfection

Grease a 1½ quart casserole dish (I use a 9-inch square one). Pour your mixture evenly into the dish and spread it out. Pop it into a preheated 350°F oven, uncovered. Bake for 40 to 45 minutes, or until the center is nearly set and the edges turn golden. You’ll know it’s done when a gentle shake shows minimal jiggle.

Step 4: Rest and Serve

Once baked, let the casserole cool for 5 to 10 minutes—it helps it firm up so when you cut into it, your slices hold together beautifully. Then serve it warm and get ready for compliments!

Pro Tips for Making Creamy Spinach and Cottage Cheese Casserole Recipe

  • Drain Your Spinach Well: I learned the hard way—too much water can turn this casserole into a watery mess.
  • Use Freshly Grated Parmesan: Pre-grated cheese can contain anti-caking agents that affect melting; fresh is worth the extra effort.
  • Don’t Rush the Resting Time: Letting it cool helps it firm up so your serving slices don’t fall apart.
  • Avoid Overbaking: Keep an eye near the end—overcooked eggs can make the casserole dry and crumbly.

The image shows a white rectangular baking dish with a spinach and cheese casserole inside. The casserole is cut into square pieces, exposing three layers: a bottom layer of white creamy cheese, a thick middle layer of cooked, dark green spinach mixed with cheese, and a top layer of slightly browned spinach and melted cheese, giving a textured green and golden look. There is a small green herb garnish on the top center of the casserole. The baking dish sits on a white marbled surface, and the edges of the dish show some baked cheese residue.

Garnishes

I like to sprinkle a bit of extra Parmesan cheese and freshly chopped parsley on top right before serving. It adds a pop of color and a fresh, herby note that complements the creaminess wonderfully.

Side Dishes

This casserole pairs beautifully with roasted chicken or grilled pork chops. I also love serving it alongside a simple tomato salad or some warm crusty bread to soak up any extra creamy goodness.

Creative Ways to Present

For special occasions, I sometimes bake this recipe in individual ramekins—it looks so elegant and makes portioning a breeze. You can even top each ramekin with a light sprinkle of breadcrumbs for a crunchy contrast.

Make Ahead and Storage

Storing Leftovers

Leftovers store really well in an airtight container in the fridge for up to 3-4 days. I always find the flavors even deepen after a day, so leftovers become just as tasty, if not better.

Freezing

I’ve frozen this casserole successfully by baking it first, allowing it to cool completely, then wrapping tightly in plastic wrap and foil. It freezes well for up to 2 months. When ready to eat, thaw overnight in the fridge before reheating.

Reheating

To keep that creamy texture, I reheat leftovers in the oven at 325°F, covered loosely with foil, for about 15-20 minutes. The microwave works in a pinch, but the oven maintains the best texture.

FAQs

  1. Can I use fresh spinach instead of frozen in this casserole?

    Absolutely! Just be sure to sauté and wilt the fresh spinach before mixing it in, and then squeeze out any excess moisture. Using fresh spinach gives a slightly lighter flavor and texture, but draining it well is key to avoid sogginess.

  2. Is this casserole suitable for keto or low-carb diets?

    This recipe is naturally low in carbs due to its focus on eggs, cheese, and spinach. If you’re following keto or low-carb, just ensure any additional ingredients align with your dietary goals. It’s a great option as-is!

  3. Can I make this casserole ahead of time and bake later?

    Yes! You can mix everything together, cover tightly, and store it in the refrigerator for up to 24 hours before baking. This makes it perfect for prepping meals in advance.

  4. What can I serve with this casserole for a complete meal?

    This casserole pairs wonderfully with roasted meats like chicken or pork, and a crisp salad or steamed veggies to round out the meal.
