Ingredients for Simple Spinach Feta Breakfast Casserole

Main Ingredients

• 3 large eggs
• 2 cups cottage cheese
• 10 oz frozen chopped spinach, thawed and well drained
• 1/3 cup crumbled feta cheese
• 1/3 cup finely diced sweet onion
• 1/4 cup unsalted butter, melted
• 2 tablespoons grated Parmesan cheese
• 1/2 teaspoon garlic powder
• 1/4 teaspoon black pepper
• Pinch of ground nutmeg

Ingredient Notes

• Spinach: Frozen spinach is convenient and consistent. Be sure to squeeze out as much liquid as possible. Excess moisture can make the casserole watery. Fresh spinach can be used if cooked and fully drained first.
• Cottage cheese: This keeps the casserole creamy and adds protein. Small curd cottage cheese blends in smoothly.
• Feta cheese: Feta adds saltiness and tang. If you prefer a milder flavor, reduce slightly or mix with crumbled goat cheese.
• Butter: Melted butter adds richness. Olive oil can be used as a lighter alternative.

Step-by-Step Instructions

Step 1: Prepare the Oven and Dish

Preheat your oven to 350°F. Lightly grease a 9-inch square baking dish or similar sized casserole dish with butter or nonstick spray.

Step 2: Drain the Spinach

Place the thawed spinach in a clean kitchen towel or several layers of paper towels. Squeeze firmly until most of the moisture is removed. This step is essential for the best texture.

Step 3: Mix the Casserole Base

In a large mixing bowl, whisk the eggs until smooth. Add the cottage cheese and stir until combined. Mix in the drained spinach, diced onion, feta cheese, melted butter, Parmesan cheese, garlic powder, black pepper, and nutmeg. Stir until everything is evenly distributed.

Step 4: Bake

Pour the mixture into the prepared baking dish and spread it out evenly. Bake uncovered for 40 to 45 minutes, or until the center is set and the top is lightly golden.

Step 5: Rest and Serve

Remove the casserole from the oven and let it rest for 5 to 10 minutes. This helps it firm up and makes slicing easier. Cut into squares and serve warm.

Pro Tips for Success

• Drain the spinach thoroughly to avoid excess liquid.
• Use room temperature eggs for smoother mixing.
• Do not overbake, as the casserole can become dry.
• Let the casserole rest before slicing for clean pieces.
• Taste your feta first, then adjust added salt if needed.

Flavor Variations

• Mediterranean style: Add chopped olives and fresh dill.
• Veggie boost: Stir in sautéed mushrooms or bell peppers.
• Herb forward: Add parsley, oregano, or chives for freshness.
• Protein option: Mix in cooked chopped chicken or turkey sausage if desired.

Serving Suggestions

Serve this casserole with fresh fruit, sliced tomatoes, or a simple green salad. It pairs well with roasted potatoes for brunch or a bowl of soup for a light dinner. Leftovers also make an excellent grab-and-go breakfast.

Storage and Freezing Instructions

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven until warmed through.

To freeze, wrap the fully cooled casserole or individual slices tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQ About Simple Spinach Feta Breakfast Casserole

Can I make this casserole ahead of time?

Yes, this casserole is ideal for making ahead. You can prepare it the night before, cover, and refrigerate. Bake it fresh in the morning, adding a few extra minutes if it goes into the oven cold.

Can I use fresh spinach instead of frozen?

Fresh spinach works well, but it must be cooked first. Sauté or steam it until wilted, then drain and squeeze out excess moisture before using.

Is this casserole keto-friendly?

This recipe is relatively low in carbs and fits many low carb lifestyles. For stricter keto needs, check the carb count of your cottage cheese brand.

Can I substitute the cottage cheese?

Yes, ricotta cheese is a good substitute and provides a similar creamy texture. Greek yogurt can also work, though it will slightly change the flavor.

How do I know when the casserole is done?

The center should be set and no longer jiggly. A knife inserted in the middle should come out mostly clean.
