Sheet Pan Frittata
Easy, sheet pan frittata that helps you hit your veggie goals, and sets you up with a delicious breakfast option for several days. No judgment if you eat it for lunch and dinner, too.
  1. If necessary, cook any veggies you’re adding to frittata. You can cook in a heated skillet (using the two teaspoons of oil) until softened, or gently steam, or microwave briefly. Leftover roasted veggies are also a great option for your veggie add-in.
  2. Set aside cooked veggies to cool.
  3. Preheat oven to 400F.
  4. Grease sheet pan *thoroughly*, including every speck of every corner, and up the sides, too.
  5. In a large mixing bowl, whisk eggs. Add egg whites and whisk to combine. Whisk salt and pepper into egg mixture. If you are adding any spices or herbs, whisk them into the egg mixture.
  6. Pour egg mixture into pan.
  7. Gently add cooked veggie (and whatever else you’ve got in there) mixture into egg mixture on sheet pan. The easiest way to do this is just to add a little bit at a time, by hand or with a spoon. Distribute the veggie mixture evenly across pan surface. (If you prefer, you can instead, add veggie mixture to the sheet pan first, and then pour egg mixture over that. Your call.)
  8. If adding cheese, sprinkle across top.
  9. Very, very carefully transfer pan to oven. I will be honest – you need a steady hand for this so you don’t end up spilling liquid eggs all over the place. I recommend sliding the oven rack out slightly before you place the sheet pan on it. And, once you’ve placed the sheet pan on the rack, slide the rack back in very slowly. (Trust me. Learn from my mistakes!)
  10. Bake for 16-18 minutes, or until eggs are set. Let cool before slicing.
