Ingredients

• 8 large eggs
• 2 cups small-curd cottage cheese (4% milk fat recommended)
• 8 oz cremini or white button mushrooms, sliced
• 3 cups fresh baby spinach, roughly chopped
• 1/2 small yellow onion, finely diced
• 2 cloves garlic, minced
• 1 cup shredded mozzarella or white cheddar cheese
• 1 tablespoon olive oil
• 1/2 teaspoon sea salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon red pepper flakes (optional for heat)

Directions

Step 1: Sauté the Vegetables

Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with non-stick spray or butter. Heat the olive oil in a large skillet over medium heat. Add the diced onions and sliced mushrooms. Sauté for about 5-7 minutes until the mushrooms have released their moisture and turned golden brown. Stir in the minced garlic and chopped spinach, cooking for just 1 minute until the spinach is wilted. Remove from heat and let it cool slightly.

Step 2: Whisk the Egg Base

In a large mixing bowl, crack the 8 eggs and whisk them thoroughly. Stir in the cottage cheese, shredded mozzarella, salt, pepper, and red pepper flakes. If you prefer a completely smooth texture where you can’t see the cottage cheese curds, you can pulse the eggs and cottage cheese in a blender for 10 seconds before adding the other ingredients. Once mixed, fold in the cooled sautéed vegetable mixture until everything is evenly distributed.

Step 3: Bake and Set

Pour the egg mixture into your prepared baking dish, spreading it out into an even layer. Place the dish on the center rack of the oven and bake for 35 to 40 minutes. The egg bake is done when the center is set and the edges are lightly golden brown. Remove from the oven and let it rest for 5 minutes before slicing. This resting period is crucial as it allows the proteins to firm up, making it much easier to cut into clean squares.

Expert Tips for Perfect High Protein Cottage Cheese Egg Bake with Mushrooms and Spinach

• Cook out the moisture: Always sauté your mushrooms and spinach before adding them to the eggs. If you add them raw, they will release water during baking, resulting in a soggy, watery egg bake.
• Use full-fat cottage cheese: For the creamiest texture, use 4% milk fat cottage cheese. Fat-free versions can sometimes result in a grainier texture.
• Don’t overbake: Eggs continue to cook for a few minutes after they come out of the oven. Pull the dish out when the center has just a slight jiggle to avoid a rubbery texture.
• Season well: Cottage cheese is naturally salty, but eggs need a good amount of seasoning. Don’t be afraid to add fresh herbs like chives or parsley to the egg base for extra depth.

Delicious Variations

• Mediterranean Style: Swap the mozzarella for feta cheese and add sun-dried tomatoes and kalamata olives.
• Meat Lover’s: Stir in cooked turkey sausage, crispy bacon bits, or diced ham for even more protein.
• Extra Veggie: Add diced bell peppers, shredded zucchini (squeezed dry), or broccoli florets to the sauté mix.
• Spicy Kick: Mix in diced jalapeños or top the finished dish with your favorite hot sauce or salsa verde.

Frequently Asked Questions

Can I use egg whites instead of whole eggs?

Yes, you can substitute the whole eggs with 2 cups of liquid egg whites. However, the texture will be slightly less rich, and the baking time may be reduced by about 5 minutes. Watch the center closely to ensure it doesn’t dry out.

How do I store and reheat the leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place a slice on a microwave-safe plate and heat for 60-90 seconds, or warm it in a 350°F oven for 10 minutes until heated through.

Can I freeze this egg bake?

Absolutely. Once the bake has cooled completely, cut it into individual portions. Wrap each square tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. Thaw in the fridge overnight before reheating.

Will I taste the cottage cheese in the final dish?

Not really! The cottage cheese melts into the eggs, giving them a rich, creamy consistency similar to a quiche filling. If you are sensitive to the texture of curds, simply blend the cottage cheese and eggs together before baking.

Why is there liquid at the bottom of my baking dish?

This usually happens if the vegetables weren’t sautéed long enough to evaporate their natural water content. It can also happen if you use low-fat cottage cheese, which has a higher water-to-protein ratio. Ensure your mushrooms are well-browned before mixing them in.
