Easy Oven Frittata Guide

Featured in Tasty Morning Favorites.

This easy frittata features whole eggs, milk, sautéed onions, a medley of seasonal vegetables, cooked protein, and a generous layer of cheese. Start by preheating your oven and prepping an oven-safe skillet, then sauté your favorite vegetables until tender. Whisk together the eggs and milk with seasonings, pour into the skillet over the veggies, and top with cheese and cooked meat if desired. Partially cook on the stovetop before finishing in the oven so the texture is just right—set but still creamy in the center. After a brief cooling period, slice and serve warm. Store leftovers in the fridge or freezer for a convenient meal anytime.

This veggie-packed frittata is my go-to solution for busy mornings and fridge cleanouts You get a savory one-pan breakfast or lunch that is endlessly flexible and always comforting

The first time I whipped up a frittata like this it was a weekend when my fridge was nearly empty Except for some spinach and a little cheese Breakfast was a hit and now I keep coming back to this recipe whenever I need something nourishing but no fuss

Ingredients

  • Eggs: They create the rich base of the frittata Use fresh eggs for the best custard texture
  • Milk: Adds creaminess and helps bind everything together Choose whole milk for richness or almond milk for dairy free
  • Diced onions: Bring sweetness and depth Shallots or green onions will work if you want a milder flavor
  • Chopped vegetables: Such as bell peppers spinach or zucchini Pick what is colorful and crisp Avoid old or overly soft vegetables for the best bite
  • Cooked protein: Bacon sausage or ham lend salty savory flavor Use whatever protein leftovers you have
  • Shredded cheese: Cheddar mozzarella or your favorite cheese melts into gooey pockets Try feta or goat cheese for tangy variation Choose cheese that is fresh and not too dry

Step-by-Step Instructions

Preheat Your Oven:
Begin by warming your oven to 350 degrees Fahrenheit or 175 degrees Celsius This ensures the oven is hot and ready when the skillet moves from stovetop to oven
Prepare the Skillet:
Pick an oven safe skillet ideally one that is 10 to 12 inches in diameter Drizzle a touch of oil then warm the pan gently over medium heat until the oil shimmers This step stops sticking and builds a base for flavor
Sauté the Vegetables:
Tip in your diced onions or any mix of vegetables you enjoy Stir them often letting them soften for about 3 to 5 minutes You want them tender but not browned as this gives the frittata sweetness not bitterness
Whisk the Eggs:
Crack your eggs into a large bowl Add your milk a pinch of salt and a few turns of black pepper Whisk vigorously until the eggs and milk blend into a smooth pale yellow mixture incorporating some air for a fluffy finish
Combine Ingredients:
Gently pour the egg mixture into the skillet over the cooked vegetables Sprinkle in your cheese and add ins like cooked bacon or greens Make sure the fillings are distributed evenly for balanced bites
Cook on Stovetop:
Let the mixture sit undisturbed on the stovetop for 5 to 7 minutes The edges should start to firm up but the middle will still be loose This forms the delicate structure for the oven finish
Transfer to Oven:
Slide the skillet carefully into your preheated oven Bake for 10 to 15 minutes or until the center is just set but still barely wobbly Insert a knife in the middle to check for doneness if unsure
Cool and Serve:
Remove the skillet from the oven and let your frittata rest for a few minutes Slicing too soon can make the eggs run wait and it will set up perfectly Enjoy in wedges on its own or with a side salad

One of my favorite tricks is stirring in a handful of tangy goat cheese after the pan comes off the heat It melts into creamy pockets My family always gathers around the table with extra enthusiasm any morning we serve this and leftovers never last long

Storage tips

Frittata keeps well in the fridge up to three days Store leftovers in an airtight container for maximum freshness If freezing let the slices cool then wrap each piece in plastic and stash in a freezer bag Frozen frittata can be reheated quickly in a microwave or oven and tastes just as delicious as when first made

Ingredient substitutions

You can personalize this frittata with almost any mix of vegetables or proteins Leftover roasted veggies grilled chicken or meatless alternatives like tofu are all fair game Swap out the milk for a dairy free alternative like unsweetened almond milk or use cream for extra rich results Changing the cheese gives you fresh flavor every time

Serving suggestions

Frittata is wonderful both warm and at room temperature Serve it with a crisp green salad or simple fruit It pairs well with toasted bread or roasted potatoes for a more filling meal Leftover wedges make a tasty sandwich stuffed into a fresh baguette

Instructions

Step 01

Preheat the oven to 175°C to ensure it reaches temperature before baking.

Step 02

Select a 25–30 cm oven-safe skillet, preferably cast iron or nonstick. Heat oil over medium heat until shimmering.
