01 - 1 cup plain Greek yogurt (2% or 0% fat)
02 - 1 cup self-rising flour, plus extra for dusting
03 - 1/2 teaspoon garlic powder
04 - 1/2 teaspoon dried oregano
05 - 1/4 teaspoon salt

→ Toppings

06 - 6 large eggs
07 - 1/2 cup low-fat milk
08 - 1 cup shredded part-skim mozzarella cheese
09 - 1/2 cup shredded cheddar cheese
10 - 1/2 cup turkey pepperoni slices
11 - 1/2 cup low-sugar pizza sauce
12 - 1/4 cup diced bell pepper, optional
13 - 1/4 cup diced red onion, optional
14 - 1 tablespoon chopped fresh basil or parsley, optional for garnish

# Directions:

01 - Preheat oven to 400°F. Lightly grease or line a 9x13-inch rimmed sheet pan with parchment paper.
02 - In a medium bowl, combine Greek yogurt, self-rising flour, garlic powder, oregano, and salt. Mix until shaggy dough forms. Knead briefly on a lightly floured surface until smooth, approximately 2-3 minutes.
03 - Roll or press dough into a rectangle to fit the prepared sheet pan. Transfer to pan and press evenly to edges.
04 - Spread pizza sauce evenly over the dough base.
05 - In a large bowl, whisk together eggs, milk, a pinch of salt, and black pepper until well combined.
06 - Sprinkle half of the mozzarella and cheddar cheese over the pizza sauce.
07 - Pour the egg mixture evenly over the cheese layer.
08 - Top with turkey pepperoni, remaining cheese, bell pepper, and red onion if using.
09 - Bake for 22-25 minutes, or until eggs are set and cheese is golden and bubbly.
10 - Remove from oven. Let cool for 5 minutes, then garnish with fresh basil or parsley if desired. Slice and serve warm.

# Expert Advice:

01 -
  • Twenty grams of protein per slice keeps you satisfied without that heavy, sluggish feeling.
  • It tastes indulgently like pizza for breakfast, which feels like getting away with something delicious.
  • Minimal prep work means you can have it ready before your coffee even brews the next morning.
02 -
  • Don't skip the 5-minute rest after baking; rushing to slice while it's piping hot will cause it to fall apart and lose all those creamy layers.
  • The eggs will continue cooking slightly as the casserole cools, so pull it from the oven when it still has the tiniest jiggle in the very center.
03 -
  • If your self-rising flour is older than a few months, it loses its leavening power—replace it with 1 cup all-purpose flour plus 1 1/2 teaspoons baking powder and 1/4 teaspoon salt mixed together.
  • Taste your pizza sauce before spreading it; some brands run salty, and you can adjust by adding a splash of water or even a teaspoon of sugar to balance it.
