What Is a Frittata?

A frittata is an Italian egg dish that's similar to an omelet or crustless quiche. The eggs are mixed with vegetables, cheese, and sometimes meat, then cooked partly on the stovetop and finished in the oven.

Unlike a quiche, a frittata doesn't have a crust, which makes it simple, lighter, and naturally gluten free. It's one of the easiest ways to make a protein-packed meal using simple ingredients.

How to Make a Veggie Frittata

Step 1: Preheat the Oven

Preheat your oven to 375°F.

Step 2: Cook the Vegetables

In a large oven-safe skillet, heat the olive oil over medium heat.

Add the diced onion and red pepper. Cook for about 4-5 minutes until softened.

Add the zucchini and spinach then continue cooking for another 4-5 minutes until tender and the spinach has wilted.

Step 3: Whisk the Eggs

In a large bowl, whisk together the eggs, salt, garlic powder, pepper, and basil.

Step 4: Combine Everything

Pour the egg mixture into the skillet over the vegetables. Stir gently so everything is evenly distributed, then sprinkle the cheese on top.

Let the frittata cook on the stovetop for 2-3 minutes until the edges begin to set.

Step 5: Bake the Frittata

Transfer the skillet to the oven and bake for 15-20 minutes, or until the center is fully set.

Let cool slightly before slicing and serving.

Tips for the Best Veggie Frittata

A few simple tips make a big difference when making a frittata.

Sauté the Vegetables First

Zucchini holds a lot of moisture, so cooking the vegetables before adding the eggs helps prevent a watery frittata.

Use Fresh Basil

Fresh basil adds so much flavor and brightness to the eggs and vegetables.

Don't Overbake

The eggs should be just set in the center. Overbaking can make the texture rubbery instead of soft and fluffy.

Use an Oven-Safe Skillet

A cast iron skillet works perfectly because it goes from stovetop to oven easily.

What to Serve with this Veggie Frittata

This veggie frittata pairs well with so many simple sides.

Some favorite serving ideas:

  • Fresh fruit
  • Roasted potatoes
  • Toast or gluten free toast
  • Simple green salad
  • Arugula with lemon and olive oil

It's perfect for brunch spreads, meal prep breakfasts, or easy dinners.

How to Store Frittata Leftovers

Store leftover frittata slices in an airtight container in the refrigerator for up to 4 days.

You can reheat slices in the microwave for about 30 seconds or enjoy them cold straight from the fridge. This recipe is great for meal prep because it holds up really well.

It's simple, wholesome, packed with fresh vegetables, and works for just about any meal of the day.

Whether you're making it for a quick weekday breakfast, meal prepping for the week, or serving it for a casual brunch, this frittata is always a good idea.
