Ingredients

This recipe yields a frittata that serves four to six people. The vegetable amounts are flexible; use what you have on hand.

• 8 large eggs
• 1/4 cup whole milk or half-and-half
• 1/2 teaspoon kosher salt, plus more for seasoning vegetables
• 1/4 teaspoon freshly ground black pepper
• 1 tablespoon olive oil or unsalted butter
• 1 small onion, diced (about 1 cup)
• 1 bell pepper (any color), diced
• 2 cups chopped vegetables (such as broccoli florets, sliced zucchini, mushrooms, or spinach)
• 1 cup shredded cheese (such as cheddar, Monterey Jack, feta, or goat cheese)
• 2 tablespoons chopped fresh herbs (optional, such as parsley, chives, or basil)

Equipment

Having the right tools makes the process smooth and safe.

• 10-inch oven-safe skillet (cast iron, stainless steel, or carbon steel are common choices)
• Mixing bowl
• Whisk or fork
• Spatula
• Cutting board and knife
• Measuring cups and spoons
• Oven mitts

Instructions

1. Position an oven rack about 6 inches below the heating element and preheat your oven’s broiler to high.
2. In a large bowl, whisk together the eggs, milk, 1/2 teaspoon salt, and black pepper until well combined and slightly frothy. Set aside.
3. Heat the olive oil or butter in your 10-inch oven-safe skillet over medium heat on the stovetop.
4. Add the diced onion and bell pepper. Cook, stirring occasionally, until they begin to soften, about 5 minutes.
5. Add your remaining 2 cups of chopped vegetables. For harder vegetables like broccoli, cook for 5-7 minutes until tender-crisp. For tender greens like spinach, just wilt them for 1-2 minutes. Season the vegetables lightly with a pinch of salt.
6. Spread the cooked vegetables evenly across the bottom of the skillet. Sprinkle about 3/4 of the shredded cheese over the vegetables.
7. Pour the egg mixture evenly over the vegetables and cheese. Let it cook undisturbed for 2-3 minutes until you see the edges just beginning to set.
8. Reduce the stovetop heat to medium-low. Cook for another 4-6 minutes until the eggs are set around the edges but the center is still slightly wet and jiggly.
9. Sprinkle the remaining cheese on top. Using oven mitts, carefully transfer the skillet to the preheated oven under the broiler.
10. Broil for 2-5 minutes. Watch it closely! The frittata is done when the top is golden brown, puffed, and the center is fully set. A food thermometer inserted into the center should read 160°F.
11. Remove the skillet from the oven (remember the handle will be extremely hot). Let the frittata rest in the skillet for 5 minutes before slicing and serving.

Food safety and storage

Egg dishes require careful handling to prevent foodborne illness.

Let leftovers cool to room temperature within two hours of cooking. Store covered in the refrigerator for 3 to 4 days. Reheat individual slices in a microwave or a warm oven until steaming hot (165°F). You can also eat leftover frittata cold. For more on safe food handling, see guidance from the USDA Food Safety and Inspection Service.

Variations

The beauty of a frittata is its flexibility. Here are a few ways to change it up.

• Meat Lover’s: Add 1/2 cup of cooked, crumbled breakfast sausage, diced ham, or crumbled cooked bacon to the vegetables before adding the eggs.
• Mediterranean: Use spinach, sun-dried tomatoes, kalamata olives, and feta cheese. Add a pinch of dried oregano to the egg mixture.
• Potato and Herb: Substitute 1 1/2 cups of cooked, diced potatoes (like Yukon Gold) for half the other vegetables. Use chives and parsley as the fresh herbs.
• For a Crowd: Double the recipe and bake it in a 9×13-inch baking dish at 350°F for 25-35 minutes, or until the center reaches 160°F.
• Individual Portions: Divide the egg and vegetable mixture among greased cups of a muffin tin. Bake at 350°F for 15-20 minutes for perfect single-serving frittatas, ideal for meal prep.

FAQ

Can I make a frittata without an oven-safe skillet?

Yes, but the method changes. Sauté your vegetables in any skillet, then transfer them to a greased pie dish or 9-inch round baking pan. Pour the egg mixture over top and bake at 350°F for 25-35 minutes, until the center is set and reaches 160°F. The texture will be more like a crustless quiche than a stovetop-started frittata.

What’s the difference between a frittata and an omelet?

An omelet is cooked quickly on the stovetop, folded over a filling, and served immediately. A frittata is typically started on the stovetop but finished under the broiler or in the oven, isn’t folded, and is often served in slices. It’s generally thicker and can be served warm or at room temperature, making it more suitable for lunch or feeding a group.

Why did my frittata turn out rubbery?

Overcooking is the most common cause. Eggs continue to cook from residual heat after being removed from the oven. Pull the frittata from the broiler when it’s just set and the thermometer reads 160°F. Letting it rest before slicing allows it to firm up perfectly. Using very high heat on the stovetop can also cause toughness.

Can I use water instead of milk?

You can, but milk (or cream) adds richness and helps create a more tender texture. Water will work in a pinch and still yield an edible frittata, but the result may be slightly less creamy.

What are good side dishes to serve with a frittata?

For breakfast or brunch, serve with toast, fresh fruit, or muffins. For lunch or a light dinner, a simple green salad, roasted potatoes, or a cup of soup are excellent complements. Like a hearty chili or sheet-pan dinner, a frittata can be the centerpiece of a satisfying meal.
