What is a Frittata?

Frittatas are made with eggs, very much like a crustless quiche or omelette, and can feature a variety of vegetables and meats. They’re egg based, and perfectly customizable to your personal taste. You can fill them up with all sorts of veggies like onions, spinach, mushrooms, kale, broccoli, asparagus and cherry tomatoes and season with your favorite herbs. You can also include meats such as sausage, bacon, ham and cheddar cheese, gruyere cheese, mozzarella cheese or crumbled feta. They’re typically fried in a skillet on the stovetop.

How to make the BEST Sheet Pan Frittata Recipe

• Heat Oven and Prepare Pan – Preheat oven to 350°F. Liberally spray a 15x10x1-inch jelly roll pan with cooking spray. Set aside.
• Sausage – Cook the sausage over medium high heat for 5-7 minutes or just until no pink remains. Remove from the pan using a slotted spoon reserving drippings in the pan. (You can add olive oil, if needed.)
• Vegetables – To the skillet add red bell pepper, green bell pepper and mushrooms. Season with 1/2 tsp salt. Cook over medium-high heat just until beginning to soften. Scrape any brown bits from the bottom of the pan. Remove from the heat.
• Assemble – Arrange cooked sausage on pan. Top with red bell pepper, green bell pepper, green onions and ribbons of basil. Sprinkle with shredded cheese.
• Eggs – Whisk together eggs, milk, ricotta, salt, pepper, granulated garlic, onion powder and ground nutmeg. Pour egg mixture evenly over ingredients in pan.
• Cheese – Sprinkle top with remaining shredded cheese and grated Parmesan cheese.
• Oven – Bake for 35-45 minutes or until the eggs are set when the pan is gently shaken. You can broil for a few minutes at the end to brown the top, if desired.
• Serve – Slice the Sheet Pan Frittata into 12 even squares and serve with your favorite breakfast sides or turn it into a breakfast sandwich.

Tips for Making Sheet Pan Frittata

• Kitchen Tools You’ll Need: Jelly roll pan or similar size half sheet pan or rimmed baking sheet, cheese grater, large bowl, measuring cups and spoons, whisk, sharp knife and chopping board.
• The Ricotta Cheese Won’t Completely Dissolve: When whisking together the eggs and ricotta you may see some lumps of ricotta cheese that don’t incorporate. This is fine!
• Use this Recipe for Meal Prep: This Sheet Pan Frittata is a fantastic technique for meal prep and make ahead meals.
• Make-Ahead Tip: You can cut down on prep time and chop the vegetables ahead of time and pop them into baggies. Refrigerate until you’re ready to make the frittata.
• How to Serve: Serve with a side of fresh fruit or a fruit salad, biscuits, hash browns or toasted bread.

Recipe Variations

• Sausage: You can use spicy or sweet Italian sausage for this frittata. You could also use turkey sausage or chorizo.
• Protein: You could replace the sauce with cooked bacon or chopped ham.
• Spice: You could also add crushed red pepper flakes to the bell peppers and mushrooms for a little kick.
• Herbs: Add any fresh herbs that you enjoy. You could use chives, thyme or rosemary.
• Vegetarian Option: You could make this frittata meatless by replacing the Italian sausage with chopped zucchini, squash or diced potatoes. When doing so, saute them in olive oil just until softened and layer with the other ingredients.

Storage and Leftovers

• Leftovers: Store frittata in an airtight container chilled in the refrigerator for up to 5 days.
• Reheating: Reheat in single servings in the microwave in 15 second increments. Repeat until heated to your liking. You can also reheat over medium heat in a skillet.
• Freezer Storage: You can also freeze frittata for up to 1 month. Separate layers with parchment paper or wax paper. Thaw in the refrigerator and reheat just before serving.
