On a chilly morning in the Bulgarian countryside, my grandmother would whisk together farm-fresh eggs and tangy white cheese, baking it until the kitchen smelled like comfort. This Cottage Cheese Egg Bake Casserole is my modern twist on that rustic memory, bringing together creamy cottage cheese, sharp cheddar, and a medley of fresh vegetables for a hearty breakfast that feels both nostalgic and new.

Why You'll Love This Recipe
About the Ingredients
1 tablespoon (15ml) olive oil
For sautéing the vegetables. You can substitute with butter or avocado oil.
1 small onion, diced (about 1 cup / 150g)
Adds sweetness and depth. Use a yellow or sweet onion for best flavor.
1 red bell pepper, diced (about 1 cup / 150g)
Provides color and a mild, sweet flavor. Any color bell pepper works.
1 cup (70g) fresh spinach, roughly chopped
Adds nutrients and a pop of green. You can use frozen spinach (thawed and squeezed) if fresh is unavailable.
8 large eggs
The base of the casserole. For best results, use room-temperature eggs.
1 cup (240ml) milk
Adds moisture and helps create a tender texture. Use whole milk or any non-dairy milk like almond or oat.
1 cup (240g) cottage cheese
The star ingredient. Use full-fat for extra creaminess, or low-fat for a lighter version.
1 cup (120g) shredded cheddar cheese
Gives a sharp, melty flavor. Substitute with mozzarella, Monterey Jack, or a dairy-free cheese.
1/2 teaspoon salt
Enhances all the flavors. Adjust to taste.
1/4 teaspoon black pepper
Adds a subtle kick. Freshly ground is best.
1/4 teaspoon garlic powder
Adds savory depth. You can use 1 clove of minced garlic instead.
Tips & Tricks
Don't overbake
The casserole is done when the edges are set and the center is just slightly jiggly. It will continue to cook as it rests.
Use a glass or ceramic baking dish
It heats more evenly than metal, preventing burnt edges and undercooked centers.
- Let it rest for 5-10 minutes after baking: This allows the casserole to set and makes slicing easier.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a 9×13-inch (23x33cm) baking dish with butter or nonstick spray.
2. Sauté the Veggies
In a large skillet, heat olive oil over medium heat. Add onion and bell pepper and cook for 3-4 minutes until softened. Add spinach and cook for another minute until wilted. Remove from heat and set aside.
3. Whisk the Egg Mixture
In a large bowl, whisk together eggs, milk, cottage cheese, salt, pepper, and garlic powder until well combined.
4. Combine All Ingredients
Stir in the sautéed vegetables and 3/4 cup of the shredded cheddar cheese into the egg mixture.
5. Pour and Top
Pour the mixture into the prepared baking dish. Sprinkle the remaining 1/4 cup of cheddar cheese evenly over the top.
6. Bake to Perfection
Bake for 35-40 minutes, until the edges are golden brown and the center is set but slightly jiggly. The top should be puffed and golden. An internal thermometer should read 160°F (71°C).
7. Rest and Serve
Remove from the oven and let rest for 5-10 minutes. Slice and serve warm.

Frequently Asked Questions
Q: Can I make this casserole ahead of time?
Yes, you can assemble the entire casserole the night before, cover it, and refrigerate. In the morning, bake it as directed, adding 5-10 minutes to the baking time since it starts cold.

Yes, use dairy-free milk (like almond or oat), dairy-free cottage cheese (or omit it), and dairy-free shredded cheese. The texture will be slightly different but still delicious.
