Create-Your-Own Sheet Pan Frittata

Holiday mornings, brunch parties, or random Tuesday nights when you are staring into the fridge and wondering what on earth to make... this Easy Sheet Pan Frittata has your back. It is my favorite way to turn leftovers and odds and ends into something warm, colorful, and honestly pretty impressive. It bakes in about 20 to 25 minutes, feeds a crowd, and is wide open to whatever you want to toss in.

This Easy Sheet Pan Frittata is built to be customized. Use the ingredients in my version as a guide, or grab whatever vegetables, cheeses, and proteins you love. The best part is how well it works for make ahead prep. All the filling ingredients can be cooked the night before or collected from leftover roasted vegetables, cooked bacon or ham, and even scraps of cheese.

Because it bakes in a thin, even layer, this frittata for a crowd cooks quickly and slices beautifully. It is perfect for holiday breakfasts, brunch potlucks, weekend meal prep, or any time you want a hands off meal that is still full of flavor.

Ingredients & Subsitutions

Simple ingredients often make the best food and the photo below shows all you need to make this amazing Sheet Pan Frittata, but remember, this is only my suggestion. You can add whatever you like to make this frittata your own! Let's go over my ingredients and a few ways you can swap them if needed:

• Bacon - Use cooked sausage, ham, or keep it vegetarian.
• Onion - Shallots or sliced leeks work well.
• Mushrooms - Any type of mushroom or roasted vegetables.
• Spinach - Kale or swiss chard also work.
• Sun-dried tomatoes - Roasted red peppers or halved cherry tomatoes will work too.
• Ricotta cheese - I love to use my homemade ricotta cheese but store-bought is fine. You sub with goat cheese, cottage cheese, or cream cheese.
• Eggs - No substitute for the structure, but you can increase to 8 or 12 for larger pans.
• Heavy cream - Use half and half or whole milk.
• Gruyere cheese - Swiss, cheddar, or Monterey jack will work great too.

Instructions

All of the steps to making your Sheet Pan Frittata, before adding the egg mixture to the sautéed ingredients, can be done the night before. All you have to do in the morning is preheat the oven while you assemble and put it in to bake. Go take a shower. Have a cup of coffee. Relax, breakfast is almost ready!

• Start by preheating your oven to 375°F Prepare your small sheet pan by spraying it with nonstick cooking spray or lining it with parchment paper (or both).

Step 1: Start by preparing your ingredients. For this frittata, I sliced my onion, mushrooms, and bacon. I also cut and drained the sun-dried tomatoes and cut them into small strips.

Step 2: In a skillet set over medium heat, I started by sautéing my bacon until almost crispy, and removing a small amount to finish my frittata. I then let the rest of the bacon cook for another minute and then put it into my prepared sheet pan.

Step 3: In the same pan, I sautéed my sliced onion with a pinch of salt and pepper along with a small pinch of sugar. I cooked them just until softened and turning a nice golden brown. A bit was set aside, and the rest was added to the bacon in the sheet pan.

Step 4: Then I sautéed my mushrooms in the same pan, waiting to season with salt and pepper until they were golden brown, setting some aside and adding the rest to the sheet pan.

Step 5: Finally, I sautéed my spinach until just barely wilted, saving some, while adding the rest of the sheet pan.

Step 6: I like to use a set of chopsticks to arrange everything on the sheet pan so that the fillings are as evenly distributed as possible.

Step 7: Then I added most of my shredded cheese, saving some for the top. I whisked my eggs with heavy cream and carefully poured it over everything.

Step 8: Then I added the rest of the shredded cheese and dollops of ricotta cheese wherever I could. I nestled my sun-dried tomatoes in the egg mixture and used my chopsticks to make sure everything was nicely arranged.

Bake: Bake your sheet pan frittata in a preheated 375°F oven for between 20 to 25 minutes or until a knife or skewer inserted into the very center comes back clean. Allow to rest and set for at least 15 minutes before slicing in.

Serving Suggestion

Whether you serve this for breakfast, brunch, or even breakfast for dinner, it always goes well with a crisp green salad or even a light tomato salad. I like to make a simple salad ahead and keep it in the refrigerator so that when The Boy comes home at midnight from working at the hospital he can warm up a slice of frittata and have his healthy greens on the side. He thinks a lot at work, and this comes together with hardly any thinking at all.
