High-Protein Pizza Breakfast Casserole (Printable Version)

A savory morning bake with Greek yogurt dough base, fluffy eggs, pepperoni, and bubbly cheese for a satisfying high-protein start to your day.

# What You 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, optional

# Steps:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch sheet pan or casserole dish.
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 smooth.
03 - Press the dough evenly into the prepared pan, forming a thin base layer.
04 - In a large bowl, whisk together eggs, milk, oregano, garlic powder, and black pepper until well combined.
05 - Pour the egg mixture evenly over the dough base. Sprinkle both cheeses over the eggs and top with turkey pepperoni slices.
06 - Bake for 20 to 25 minutes, or until the eggs are set and the cheese is golden and bubbly.
07 - Let cool for 5 minutes, then garnish with fresh parsley if desired. Slice and serve warm.

# Expert Pointers:

01 -
  • It tastes indulgent while delivering serious protein (22g per slice) that keeps you full until lunch.
  • Everything happens in one pan, so cleanup won't steal your Sunday morning joy.
  • Meal prep magic—slice it cold, reheat it, throw it in a container, and you're set for the week.
02 -
  • Don't skip the cooling step—those five minutes make all the difference between a falling-apart slice and one that holds together beautifully.
  • If your oven runs hot, start checking at 20 minutes; if it runs cool, give it the full 25 and watch the cheese color rather than the clock.
03 -
  • Let your Greek yogurt sit at room temperature for a few minutes before mixing; it incorporates into the flour more smoothly and creates a more tender base.
  • Watch the cheese color rather than the timer—when it's bubbly and just starting to turn golden at the edges, you've hit the sweet spot every time.
