A quick and easy sheet pan breakfast recipe combining eggs, cheese, and veggies baked into fluffy, cheesy egg muffins perfect for busy school mornings.

Ingredients

Scale
  • 8 large eggs, room temperature
  • ½ cup (120 ml) milk, whole or 2%
  • 1 cup (100 g) shredded cheddar cheese
  • ½ cup (75 g) diced bell peppers (red or yellow)
  • 1 cup (30 g) fresh chopped spinach
  • 2 stalks green onions, sliced
  • ½ teaspoon salt
  • ¼ teaspoon freshly ground black pepper
  • ¼ teaspoon garlic powder (optional)
  • 1 tablespoon olive oil

Instructions

  1. Preheat the oven to 350°F (175°C). Grease your sheet pan evenly with olive oil or line with parchment paper to prevent sticking.
  2. Chop the vegetables: dice bell peppers, slice green onions, and roughly chop fresh spinach.
  3. In a large mixing bowl, whisk together 8 large eggs and ½ cup (120 ml) milk until combined and slightly frothy.
  4. Add seasonings: stir in ½ teaspoon salt, ¼ teaspoon black pepper, and optional ¼ teaspoon garlic powder.
  5. Fold in the diced bell peppers, chopped spinach, sliced green onions, and 1 cup shredded cheddar cheese until evenly distributed.
  6. Pour the mixture onto the prepared sheet pan, spreading it evenly to about 1-inch thickness.
  7. Bake for 20-25 minutes or until the eggs are fully set and edges start to turn golden brown. A toothpick inserted in the center should come out clean.
  8. Remove from oven and let cool for 5 minutes to firm up.
  9. Cut into squares or rectangles, yielding about 12 pieces.
  10. Serve warm or pack for later. Reheat in microwave or toaster oven as needed.

Notes

Use room temperature eggs for even cooking and fluffier texture. Fold veggies gently to avoid deflating eggs. If edges brown too fast, tent pan with foil halfway through baking. Line pan with parchment or use olive oil to prevent sticking. Can add cooked meats or substitute cheeses as desired.
