Why Make This Sheet Pan Veggie Omelet With Spinach And Feta Feeds 12

It is incredibly healthy, low-carb, and gluten-free, making it a safe bet for guests with various dietary needs.

Ingredients
18 large eggs
1/2 cup whole milk or heavy cream
4 cups fresh baby spinach, roughly chopped
1 cup crumbled feta cheese
1 large red bell pepper, finely diced
1/2 small red onion, finely diced
1/2 teaspoon sea salt
1/4 teaspoon ground black pepper
1/2 teaspoon dried oregano
Non-stick cooking spray or parchment paper
Fresh parsley for garnish (optional)
Directions
Step 1: Preparation
Preheat your oven to 375°F (190°C). Line a standard 18×13 inch rimmed baking sheet (half-sheet pan) with parchment paper, ensuring the paper comes up the sides. Spray the parchment lightly with non-stick cooking spray to ensure the eggs release easily after baking. Finely dice your red pepper and onion, and give the spinach a rough chop so it distributes evenly.
Step 2: Whisk the Egg Base
In a very large mixing bowl, crack all 18 eggs. Add the milk, salt, black pepper, and dried oregano. Whisk vigorously for about 2 minutes until the mixture is completely combined and slightly frothy. This aeration is the secret to a light and fluffy omelet texture.
Step 3: Combine and Pour
Stir the chopped spinach, diced red peppers, and red onions directly into the egg mixture. Once combined, pour the mixture onto the prepared sheet pan. Use a spatula to spread the vegetables out so every slice gets an equal amount of toppings. Sprinkle the crumbled feta cheese evenly over the top of the egg mixture.
Step 4: Baking
Carefully place the sheet pan in the center rack of the oven. Bake for 20 to 25 minutes. You will know it is done when the edges are golden brown and the center is set and no longer jiggles when you gently shake the pan. Do not overbake, or the eggs may become rubbery.
Step 5: Plating
Remove the pan from the oven and let it cool for 5 minutes. This resting period allows the omelet to firm up, making it easier to cut. Use a knife or a pizza cutter to slice the omelet into 12 even squares. Garnish with fresh parsley if desired and serve immediately with toast or fresh fruit.
Expert Tips for Perfect Sheet Pan Veggie Omelet With Spinach And Feta Feeds 12
For the best results, always use a rimmed baking sheet to prevent spills in your oven. If you want an extra boost of flavor, sauté the onions and peppers for 3 minutes before adding them to the egg mix; this softens their texture and sweetens the flavor. Ensure your feta is high quality, as the saltiness of the cheese provides most of the seasoning. Lastly, if you are worried about sticking, parchment paper is much more reliable than just greasing the pan.
Delicious Variations
You can easily customize this base recipe to suit your cravings. For a meat-lover’s version, add a cup of cooked crumbled bacon or breakfast sausage. If you prefer a bit of heat, mix in some diced jalapeños or top the finished squares with a drizzle of sriracha. You can also swap the feta for sharp cheddar or goat cheese. If you have other veggies in the fridge, like mushrooms or zucchini, feel free to toss them in, just make sure to dice them small so they cook through.
Frequently Asked Questions
Can I make this omelet ahead of time?
Yes, this is an excellent meal prep recipe. You can bake it, let it cool completely, and store the squares in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 30-45 seconds.
Can I freeze the sheet pan omelet?
Absolutely. Wrap individual squares in plastic wrap and store them in a freezer-safe bag for up to 2 months. Thaw them overnight in the fridge or reheat directly from frozen in the oven at 350°F until warmed through.
What is the best way to prevent the omelet from being watery?
If you use frozen spinach, make sure to thaw it and squeeze out every drop of excess moisture before adding it to the eggs. Fresh vegetables usually don’t cause issues, but avoiding high-moisture additions like raw tomatoes can help keep the texture firm.
Can I use egg whites only?
Yes, you can substitute the whole eggs with approximately 4 cups of liquid egg whites. Keep in mind that the omelet will be much leaner and may bake slightly faster, so start checking for doneness at the 15-minute mark.
What should I serve with this for a full brunch?
This omelet pairs perfectly with crispy hash browns, a side of fresh mixed berries, or a simple arugula salad with a light lemon vinaigrette. It also works great stuffed inside a toasted bagel or croissant for a quick breakfast sandwich.
