The Easiest Frittata Recipe
Keep it simple. A frittata is essentially an oven-baked omelet without a crust, which makes it quicker and easier to prepare than a quiche. The most flexible part of the recipe is the mix of vegetables: use whatever you have on hand and tailor the flavors to your taste.
This version focuses on peppers, zucchini, and onions for a reliable, colorful result, but you can swap or add vegetables as you like.

Frittata FAQ
Quick answers to common questions about making frittata:
What pan should I use?
Use a 10-inch nonstick, oven-safe skillet for best results. Avoid pans with rubber or plastic parts; choose a sturdy metal or cast-iron skillet that can go from stovetop to oven.
Can I make mini frittatas?
Yes — baked in a muffin tin, small frittatas are often called egg cups or mini frittatas. They’re great for grab-and-go breakfasts and freezing individually.
Why would my frittata be watery?
Excess moisture usually comes from undercooked vegetables. Sauté veggies with a pinch of salt until they release and evaporate their water. Mushrooms and zucchini in particular need extra time to reduce moisture.
What can I serve with a frittata?
It pairs well with a light breakfast salad, crunchy toast, roasted breakfast potatoes, or breakfast meats. Top with a little cheese or a dash of hot sauce if you like.
Can I freeze a frittata?
Yes. Cool completely, wrap tightly in plastic and foil, and freeze for up to three months. Thaw overnight in the refrigerator, then reheat in a 350°F oven for about 10–15 minutes until warmed through.
Tips & Tricks
- Whisk the eggs well. Beat until yolks and whites are fully combined but not frothy. Properly mixed eggs set evenly and give a uniform texture.
- Cook vegetables first. Sautéing removes excess water and concentrates flavor, so your frittata won’t be watery and will taste richer.
- Use consistent cuts. Chop vegetables into uniform, bite-sized pieces so they cook at the same rate and distribute evenly throughout the frittata.
- Season in stages. Season the vegetables while sautéing and taste the egg mixture before baking to adjust salt and pepper.
Vegetable ideas to swap in or add: potatoes, sun-dried tomatoes, squash, carrots, asparagus, mushrooms, spinach, or roasted peppers.
How to Make Frittata
Prep
Preheat the oven to 375°F (190°C). Dice the vegetables into bite-sized pieces and set aside. In a large bowl, whisk together 8 large eggs and 1/4 cup milk (or any milk you prefer) until combined. Set aside.
Sauté
Heat 1 tablespoon olive oil in a 10-inch nonstick, oven-safe skillet over medium-high heat. Add 2 teaspoons minced garlic, 1/4 cup diced yellow onion, 1/2 cup diced red bell pepper, 1/2 cup diced green bell pepper, and 1 cup quartered zucchini. Season with about 1 teaspoon kosher salt and freshly ground black pepper to taste. Sauté for 4–6 minutes until the vegetables are softened and the onions are translucent. If you want extra flavor, add 1–2 teaspoons of your favorite seasoning to the vegetables while they cook.
Bake & Serve
Lightly spray or oil the pan sides, then pour the egg mixture evenly over the vegetables, making sure everything is submerged. Transfer the skillet to the preheated oven and bake at 375°F for 16–18 minutes, or until the center is set and a knife inserted into the middle comes out clean. Remove from oven and let rest for a few minutes before slicing. Optional: crumble goat cheese or sprinkle grated parmesan on top before serving.
Storage & Reheating
Cool the frittata completely before storing. Keep in an airtight container in the refrigerator for up to 5 days. To reheat, place slices on a baking sheet and warm in a 350°F oven for about 15–20 minutes, or until heated through. For frozen portions, thaw overnight in the fridge before reheating.
