Roasted Vegetable Frittata: A Cozy Brunch Classic You’ll Crave

A Weekend Morning in My Kitchen

There’s something comforting about weekend mornings in my kitchen. The light filters through the windows just right, and the fridge always holds a surprise or two—usually leftover roasted vegetables from Friday night’s dinner. That’s when I reach for eggs and my trusty cast iron skillet, ready to make one of my favorite go-to meals: a Roasted Vegetable Frittata.

It all started one lazy Sunday. I had roasted some cauliflower, bell peppers, and potatoes the night before, and I wasn’t in the mood to toss them or eat them cold. Instead, I whisked up a few eggs, poured them over the sizzling veggies, and added a handful of mozzarella. Twenty minutes later, I was hooked.

Now, making this roasted veggie frittata is a weekend ritual—perfect for brunch or as a savory slice alongside a simple salad. If you love the idea of transforming humble leftovers into something amazing, you’ll adore this recipe. It’s the kind of dish that gives leftovers a second life and makes you feel like a kitchen genius.

It also pairs perfectly with other savory bites like Egg and Cheese Toasts or something heartier like a Whole Roasted Cauliflower, giving your brunch table a wholesome variety of flavor-packed options.

Why Roasted Veggies Make the Best Frittata

Using roasted vegetables in a frittata isn’t just a clever way to reduce food waste—it’s also a flavor booster. When veggies are roasted, they develop deeper, sweeter, and slightly caramelized notes. This means your frittata starts off with already delicious ingredients.

From crispy Brussels sprouts to charred onions or sweet roasted squash, every combination brings its own magic. That’s what makes the Easy Cheesy Roasted Vegetable Frittata so adaptable. Don’t be afraid to mix and match what’s on hand. Whether it’s the leftovers from your Maple Bacon Brussels Sprouts or some roasted mushrooms, they’ll all play beautifully with eggs and cheese.

Another bonus? Roasting concentrates the moisture, so your frittata won’t get watery, which is often a problem when using raw vegetables. It’s a simple switch that yields a firm, sliceable result with a tender texture inside and a golden crust on top.

Mastering the Roasted Vegetable Frittata Recipe

The Simple Ingredients You Need

One of the best things about this dish is how it transforms a few kitchen staples into something comforting and flavorful. Here’s what you’ll need to make a classic Roasted Vegetable Frittata:

• 2 cups leftover roasted vegetables – Anything goes: roasted sweet potatoes, bell peppers, onions, zucchini, even leftover Vegan Green Bean Casserole or a few bits of Healthy Stuffed Acorn Squash.
• 10 large eggs – Room temperature is best for a fluffy frittata.
• 2 tbsp milk – Helps lighten the texture. Any milk or non-dairy version will work.
• 1 tbsp olive oil – For sautéing the veggies before baking.
• ½ cup shredded cheese – Mozzarella, fontina, feta, cheddar, or even a mix.
• ½ tsp salt & ¼ tsp pepper – Adjust to your taste.

This simple ingredient list allows for flexibility, especially when you have bits of leftover roasted veg begging to be used. If you want to go plant-based, you can even use Just Egg to make a delicious Just Egg Roasted Veggie Frittata.

For meal-prep lovers, this recipe pairs beautifully with sides like a Roasted Pumpkin Quinoa Salad or reheats well next to Air Fryer Baked Potatoes.

How to Make Roasted Vegetable Frittata: Step-by-Step

This method is tried, tested, and delivers a fluffy, golden frittata every single time.

1. Preheat your oven to 350°F (175°C).
   You want the oven hot and ready for a quick transition from stovetop to bake.
2. Heat the veggies.
   Place a large cast iron skillet over medium heat. Add the olive oil, then spread your roasted vegetables in an even layer. Sauté for 3–5 minutes until warmed through.
3. Whisk the eggs.
   In a large bowl, beat the eggs with the milk, salt, and pepper until fully combined and slightly frothy.
4. Pour and top with cheese.
   Pour the egg mixture evenly over the vegetables in the skillet. Sprinkle your shredded cheese over the top, letting it sink slightly into the eggs.
5. Cook gently on the stovetop.
   Let it cook undisturbed for 2–3 minutes, just until the edges begin to set.
6. Bake.
   Transfer the skillet to your preheated oven and bake for 18–20 minutes. The center should puff up and feel firm to the touch. Avoid overbaking—remember, it will continue to cook slightly after it’s out of the oven.
7. Let it rest.
   Remove and let it cool for 5–10 minutes before slicing. The frittata will deflate a little—totally normal!

This process works wonderfully whether you’re cooking a Vegetable Frittata with Roasted Potatoes or a lighter, low-carb version with zucchini and peppers. And the smell as it bakes? Absolutely irresistible.

Creative Twists on the Classic Roasted Veggie Frittata

Fun Variations to Make It Your Own

One of the best parts about frittatas is how endlessly customizable they are. With just a few tweaks, you can turn this recipe into something brand new every time.

1. Use seasonal or themed vegetables
Depending on the season, switch up the vegetables. In the fall, try roasted butternut squash, Brussels sprouts, and sweet potatoes. In the summer, use grilled zucchini, tomatoes, and eggplant. Even leftovers from a Vegan Mushroom Lentil Loaf can find a new home here.

2. Add roasted potatoes for a hearty twist
For a more filling meal, go for a Vegetable Frittata with Roasted Potatoes. Cube the potatoes small so they distribute evenly and give every bite some heartiness. They add a wonderful crispy edge where they touch the skillet.

3. Try a Just Egg vegan version
If you’re plant-based or cooking for someone who is, swap the eggs for Just Egg. It mimics the texture of real eggs beautifully and still lets the roasted veggies shine. Pair this Just Egg Roasted Veggie Frittata with a side of Vegan Green Bean Casserole for a full vegan meal.

4. Play with cheese combinations
Feta adds a salty tang, mozzarella gives you gooey pull, and fontina melts like a dream. Use one, use three, or skip it if you’re dairy-free. There’s no wrong move.

5. Add fresh herbs or spices
A handful of chopped parsley or basil adds brightness. Want a smoky kick? Toss in some smoked paprika or roasted garlic. It’s your canvas—paint it bold.
