Ingredients and Pantry Staples

• ½ cup shredded cheddar cheese
• ½ teaspoon garlic powder
• ½ teaspoon Italian seasoning

• ¼ teaspoon ground black pepper

Step-by-Step Directions

1. Preheat oven to 375°F and spray a 9×13-inch baking pan with cooking spray.
2. Dice the red bell pepper and yellow onion and chop the spinach into bite-sized pieces.
3. Spread the chopped veggies evenly across the bottom of the prepared baking pan.

4. Crack 12 large eggs into a large bowl and whisk until combined and yolks are broken.

   

5. Add 16 ounces cottage cheese, ½ teaspoon garlic powder, ½ teaspoon Italian seasoning, ½ teaspoon kosher salt, ¼ teaspoon black pepper, and ¼ cup shredded gruyere/gouda to the eggs; mix until smooth.
6. Pour the egg and cottage cheese mixture evenly over the veggies in the pan and spread to distribute.
7. Sprinkle the remaining ½ cup shredded cheddar cheese evenly over the top.

8. Bake on the middle rack until the eggs are set in the center and pulling away from the edges, about 50 to 55 minutes; check doneness with a clean knife (it should come out mostly clean).

   
9. Remove from the oven and let the bake rest for at least 15 minutes to firm up.

10. Slice into squares and serve.

    

Expert Tips and Tricks

• Pick good quality eggs – I love using large, pasture-raised eggs for their rich flavor and fluffy bake, but honestly, any eggs will do just fine.
• Go full-fat with the cottage cheese – I used the Good Culture 4% fat version for the creamiest texture and best taste. The same choice makes these Cottage Cheese Protein Pancakes extra fluffy, too.
• Chop your veggies small and evenly – this helps the egg bake cut neatly into squares and looks beautiful on each slice, making every bite perfectly balanced.
• Let the bake rest – cooling it for 15 minutes after baking helps it set up nicely so it slices cleanly and serves beautifully.

Easy Swaps and Add-Ins

• Add cooked sausage or crispy bacon if you want to boost the protein and add some smoky flavor.
• Try swapping the veggies with cooked mushrooms, kale, chopped asparagus, or steamed broccoli for a fresh twist.
• Mix up the cheese! Colby jack, mozzarella, or shredded gruyere all melt beautifully and bring different flavor profiles — and if you’re adding broccoli, cheddar is a natural fit (think high-protein broccoli cheddar soup).
• Go lighter with the eggs – if you prefer, swap some or all of the eggs for egg whites (one egg equals about 3 tablespoons of egg whites) for a leaner version.

Storage and Make-Ahead Tips

Leftover egg bake? No problem! Store the slices in an airtight container with parchment paper between each piece in the fridge. They’ll stay fresh for up to four days, making quick breakfasts throughout the week a breeze. When you’re ready to eat, just pop a slice in the microwave and heat until warmed through. For variety, you can also prep Baked Apple Cinnamon Cottage Cheese Breakfast Bowls for easy mornings.

Heads up: I don’t recommend freezing this egg bake. Eggs and freezing don’t always play nicely, and the texture can get watery or rubbery when thawed and reheated.

Common Questions Answered

Why is my egg bake rubbery?

Eggs turn rubbery when they overcook. Ovens can be a bit tricky to navigate, so I recommend checking your egg bake about halfway through baking and adjusting the time accordingly to avoid overbaking.

Can you taste the cottage cheese in this recipe?

The cottage cheese melts into the eggs while baking, adding creaminess and making the bake fluffy and cheesy without a strong cottage cheese taste. If you prefer a sweeter breakfast where cottage cheese blends in the same way, try these High-Protein Blueberry Cottage Cheese Muffins.

Why are my eggs watery?

Watery eggs usually mean they need a bit more baking time. Oven temperatures and pans can vary, so if your egg bake isn’t set in the middle or edges, just pop it back in for a little longer until it firms up. For a clear look at a set, custardy center, check out my Puff Pastry Breakfast Tart.
