Ingredients You’ll Need

This recipe is delightfully simple, using a handful of ingredients that each bring something important to the table. From creamy cheeses to fragrant herbs, every item builds layers of flavor and texture that make this casserole shine.

• Fresh spinach (4 cups, chopped) or frozen spinach: Provides that vibrant green color and a healthy dose of nutrients with mild flavor.
• Crumbled feta cheese (1 cup): Adds tangy creaminess and a bit of salty punch essential to the dish’s character.
• Large eggs (4): The binding agent that turns this mixture into a satisfying, custardy casserole.
• Heavy cream (1 cup): Brings richness and smoothness to the texture, creating a luscious base.
• Shredded mozzarella cheese (1/2 cup): Melts perfectly on top for that golden, bubbly crust you dream about.
• Grated Parmesan cheese (1/4 cup): Adds a sharp, nutty flavor that complements both the spinach and feta.
• Minced garlic (2 cloves): Infuses the casserole with savory warmth and depth.
• Salt and pepper to taste: Essential to highlight and balance all the other flavors.
• Dried oregano (1 teaspoon): A subtle herbaceous note that beautifully ties everything together.

How to Make Keto Spinach and Feta Casserole

Step 1: Preheat and Prepare Your Oven

Start by preheating your oven to 350°F (175°C). This ensures the oven is at the perfect temperature to cook your Keto Spinach and Feta Casserole evenly and develop that gorgeous golden top.

Step 2: Whisk Together the Custard Base

In a large mixing bowl, whisk the eggs, heavy cream, minced garlic, dried oregano, salt, and pepper until fully combined. This mixture forms the creamy custard that holds the casserole together, giving it a rich and silky texture.

Step 3: Combine the Spinach and Cheeses

Fold in the chopped fresh or thawed spinach, crumbled feta cheese, and half of the shredded mozzarella cheese. The spinach adds freshness and slight earthiness, while the cheeses provide a salty tang and gooey delight that makes each bite so satisfying.

Step 4: Assemble Your Casserole

Grease a 9×9-inch baking dish lightly to prevent sticking. Pour the spinach and cheese mixture into the dish, smoothing it out evenly. Sprinkle the remaining mozzarella and Parmesan cheeses on top—the cheeses on top are what become irresistibly bubbly and golden when baked.

Step 5: Bake to Perfection

Place the dish in the oven and bake for 30 to 35 minutes. You’ll know it’s done when the casserole is set in the center and the top is beautifully golden and slightly crisp. Let it cool for a few minutes before slicing so it holds together nicely.

How to Serve Keto Spinach and Feta Casserole

Garnishes

Sprinkle some fresh chopped parsley or a pinch of red pepper flakes over the top to add an extra pop of color and a mild kick of heat. A drizzle of extra virgin olive oil enhances the casserole’s richness and brings a fresh finish that’s delicious.

Side Dishes

This casserole pairs wonderfully with light keto-friendly sides such as a crisp green salad dressed in lemon vinaigrette or roasted garlic asparagus. The freshness of these sides perfectly balances the casserole’s creamy, cheesy richness.

Creative Ways to Present

Try serving the casserole in individual ramekins for an elegant touch at a dinner party or layer it atop a bed of zoodles for a truly low-carb meal. You can even cut it into mini portions for dips or finger food at gatherings—each way makes this Keto Spinach and Feta Casserole feel special.

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftovers in an airtight container in the refrigerator. The casserole tastes even better the next day as the flavors meld beautifully, and it will keep well for up to 3 days.

Freezing

If you want to save some for longer, this casserole freezes beautifully. Wrap it tightly with aluminum foil or place portions in freezer-safe containers. It can be kept frozen for up to 2 months without losing its creamy texture or flavor.

Reheating

To reheat, thaw if frozen and warm in a 350°F oven for 10 to 15 minutes until heated through. Alternatively, microwave individual portions to enjoy a quick and satisfying meal. Avoid overheating to keep the texture smooth and prevent the cheese from becoming rubbery.

FAQs

Can I use frozen spinach instead of fresh for this casserole?

Absolutely! Frozen spinach works perfectly as long as you thaw and drain it thoroughly to avoid excess moisture in your Keto Spinach and Feta Casserole, which could make it soggy.

Is this casserole suitable for meal prep?

Yes! It’s an excellent choice for meal prep because it reheats well and remains flavorful. Making a batch ahead saves time while keeping your meals satisfying and keto-friendly.

Can I substitute the feta cheese with another cheese?

You can try goat cheese or even a mild ricotta for a different twist. Just keep in mind that feta’s tang and saltiness are key to the classic flavor profile of the Keto Spinach and Feta Casserole.

How many carbs are in a serving of this casserole?

This casserole is low in carbs due to its focus on spinach, cheeses, and eggs, making it ideal for keto diets. Exact carb count depends on portion size, but it’s generally just a few grams per serving.

Can I add other vegetables to the casserole?

Certainly! Mushrooms, zucchini, or bell peppers can be folded in to add variety and extra nutrition. Just make sure to chop them finely and sauté if they release a lot of moisture.

Final Thoughts

I can’t recommend trying the Keto Spinach and Feta Casserole enough. It’s one of those dishes that feels both indulgent and nourishing, perfect for any day you want a comforting, homemade meal that supports your keto lifestyle.
