Baking eggs in a sheet pan tray? I was skeptical at first but this is so easy and a great way to make a batch of eggs for quick breakfast sammies for the week. I even liked stacking 2 as if they’re low-carb pancakes 😆🙈 and top with salsa or a roasted tomato sauce. It was insanely delicious!
The key to keeping the eggs from sticking in the sheet pan? Parchment paper and cooking spray. Spray your tray and line it with a sheet of parchment. Make sure to spray the edges of your sheet pan tray to reduce chance egg sticks. I also do not over fill the sheet tray.
What to Love About Simple Sheet Pan Eggs
When it comes to meal prep I love keeping it super simple and efficient. This is a recipe that can be prepped in 30 minutes and you'll have multiple servings for the week ahead. I love the versatility of these sheet pan eggs. Use them in breakfast tacos, simple breakfast sandwiches, or chop up to fill your favorite breakfast burrito.
Ingredients for These Simple Sheet Pan Eggs
Makes 8 medium squares for breakfast sandwiches
INGREDIENTS
6 large eggs
½ cup egg whites
2 tablespoons heavy cream or whole milk
½ teaspoon kosher salt
¼ teaspoon ground black pepper
dash of hot sauce
½ cup frozen mushrooms
1 medium zucchini, ends trimmed and diced
2 cups of chopped spinach or other dark leafy greens
½ yellow onion, diced
½ cup grated Gruyère
2 tablespoons unsalted butter
1 tablespoon roasted cherry tomatoes (could also use fresh here; see note below)
Store leftover eggs in a container in the fridge for up to 3 days.
How to Make These Simple Sheet Pan Eggs
Preheat oven to 375 degrees Fahrenheit. Line a rimmed baking sheet with 2 overlapping pieces of parchment paper, making sure the sides of parchment cover the rimmed edges of baking sheet. Spray with cooking spray and set to the side while you prepare your egg mixture.
In a large nonstick skillet, heat 2 tablespoons unsalted butter over medium heat. Once melted, add in your onions and allow them to caramelize, stirring occasionally, about 7 to 10 minutes. Onions should be fragrant and brown, but not burnt. Scoop onions into a prep bowl and set to the side. To the same skillet, add in your zucchini and frozen mushrooms and allow veggies to cook until softened and liquid evaporates, about 7 to 10 minutes. Add your greens and cook until wilted. While the veggies cook, prep your egg mixture.
Note: if using fresh cherry tomatoes, cook with zucchini and mushrooms until softened and juices are released. You want to do this to ensure your eggs aren’t too runny or liquidy upon baking in oven.
In a large bowl, whisk your eggs, egg whites, hot sauce, salt, pepper, and milk—or cream—until frothy. Set aside and grate your cheese in a small bowl. Set to the side and begin assembling your sheet pan eggs.
To assemble the sheet pan eggs:
- Spread out your caramelized onions as the base layer on your parchment lined baking sheet.
- Add your zucchini, mushroom, tomato, and spinach mix then use a spatula to spread out evenly with the onions. Sprinkle your cheese evenly across the veggies.
Place the baking sheet on center rack of oven, with the center rack pulled halfway out. Whisk your egg mixture once more to re-incorporate all ingredients, then gently pour directly onto the prepared baking sheet. Carefully push the center rack back into the oven fully.
- Bake the eggs for 15 to 20 minutes until the center is set and not jiggly. Remove from oven.
- Cool 5 to 10 minutes before slicing into squares to serve.
