Equipment

  • Rimmed sheet pan, about 13×18 inches
  • Parchment paper
  • Large mixing bowl
  • Whisk
  • Measuring Cups and Spoons
  • Cutting board
  • Sharp knife
  • Spatula

Ingredients
  

For the Frittata

  • 12 large eggs
  • 1/2 cup whole milk
  • 1/2 cup shredded cheddar cheese
  • 1/2 cup crumbled feta or shredded mozzarella
  • 1 cup chopped baby spinach
  • 1/2 cup diced red bell pepper
  • 1/2 cup diced zucchini
  • 1/4 cup sliced green onions
  • 1/2 cup cherry tomatoes halved
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried Italian seasoning
  • 1 tablespoon olive oil for the pan

Instructions
 

Step 1: Preheat the oven

  • Preheat your oven to 375°F. Line a rimmed sheet pan with parchment paper and brush it lightly with olive oil.

Step 2: Prepare the vegetables

  • Chop the spinach, dice the bell pepper and zucchini, slice the green onions, and halve the cherry tomatoes. Try to keep the pieces small so they cook evenly.

Step 3: Whisk the eggs

  • In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and Italian seasoning until smooth.

Step 4: Add cheese and vegetables

  • Stir in the cheddar cheese, feta or mozzarella, spinach, bell pepper, zucchini, green onions, and tomatoes.

Step 5: Pour into the sheet pan

  • Carefully pour the egg mixture into the prepared sheet pan. Use a spatula to spread the vegetables evenly.

Step 6: Bake the frittata

  • Bake for 16 to 20 minutes, or until the eggs are set in the center and the edges are lightly golden.

Step 7: Let it rest

  • Remove the pan from the oven and let the frittata rest for 5 minutes. This makes it easier to slice.

Step 8: Slice and serve

  • Cut into squares and serve warm. Add extra herbs, hot sauce, or avocado if you like.
