Ingredients
Scale
- 12 large eggs
- 1 cup cottage cheese (2% or full fat for fluffiness)
- 1/2 cup milk (any kind)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup shredded cheddar cheese
- 1 cup cooked protein (e.g., crumbled sausage, diced ham, or turkey bacon)
- 1 cup chopped vegetables (e.g., spinach, bell peppers, or broccoli florets)
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- In a large bowl, whisk together the eggs, cottage cheese, milk, salt, and pepper until the mixture is smooth and slightly frothy. This helps create a fluffy texture.
- Fold in the shredded cheddar cheese, cooked protein, and chopped vegetables. Mix gently to distribute ingredients evenly.
- Pour the entire mixture into the prepared baking dish.
- Bake for 30 to 35 minutes, or until the center is set and a knife inserted near the middle comes out clean. The top should be lightly golden.
- Let the egg bake rest for 5 minutes before slicing and serving. This is a great make ahead breakfast casserole.
Notes
- For a keto egg bake low carb version, skip any starchy fillers like bread or hash browns and focus on high-fat meats and low-carb vegetables like spinach or mushrooms.
- To make this a high protein egg bake, use an extra 1/2 cup of cottage cheese or add cooked ground turkey.
- You can prepare this entire casserole the night before, cover it, and refrigerate. Add 5-10 minutes to the baking time if baking directly from the refrigerator.
