High-Protein Pizza Breakfast Casserole (Printable)

Protein-packed morning bake with yogurt dough, eggs, pepperoni and cheese

# What You'll Need:

→ Greek Yogurt Dough

01 - 1½ cups all-purpose flour
02 - 2 teaspoons baking powder
03 - ½ teaspoon salt
04 - 1 cup plain Greek yogurt, nonfat or 2%

→ Toppings

05 - 8 large eggs
06 - ½ cup low-fat milk
07 - 1 cup shredded part-skim mozzarella cheese
08 - ½ cup shredded reduced-fat cheddar cheese
09 - ½ cup turkey pepperoni slices
10 - ½ teaspoon dried oregano
11 - ½ teaspoon garlic powder
12 - ¼ teaspoon black pepper
13 - 2 tablespoons chopped fresh parsley

# Method:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch sheet pan or casserole dish with cooking spray or butter.
02 - In a medium bowl, whisk together flour, baking powder, and salt. Add Greek yogurt and mix with a spoon until a shaggy dough forms. Knead briefly until the texture becomes smooth.
03 - Transfer dough to the prepared pan and press evenly to form a thin, even base covering the bottom.
04 - In a large bowl, whisk together eggs, milk, oregano, garlic powder, and black pepper until fully combined.
05 - Pour the egg mixture evenly over the dough base, distributing it across the entire surface.
06 - Sprinkle mozzarella and cheddar cheese over the eggs. Distribute turkey pepperoni slices evenly across the top.
07 - Bake for 20-25 minutes until eggs are completely set and cheese is golden and bubbly.
08 - Remove from oven and let cool for 5 minutes. Garnish with fresh parsley if desired. Slice into portions and serve warm.

# Expert Advice:

01 -
  • It tastes decadent like breakfast pizza but actually keeps you full for hours because of all that protein.
  • You can slice it, freeze it, and grab pieces throughout the week when mornings feel impossible.
  • No one suspects it's healthier than it has any right to be.
02 -
  • Don't skip pressing the dough thin—a thick base makes the casserole feel heavy and means the eggs never fully set in the center.
  • If your oven runs hot, check at 20 minutes because overbaked eggs turn rubbery and the whole thing suffers.
03 -
  • Don't let the Greek yogurt dough intimidate you—it's more forgiving than traditional dough and comes together in under two minutes.
  • If you find the eggs aren't setting by 23 minutes, tent the pan loosely with foil so the top doesn't brown further while the center finishes cooking.
