How to Make Healthy Vegetable Frittata (Step-by-Step)
Follow these simple steps to create your homemade frittata.
Step 1: Preheat the Oven
Let’s kick things off by preheating your oven to 350°F (175°C) as I prepare my ingredients. A hot oven is essential for that perfect frittata texture.
Step 2: Sauté the Vegetables
In a large, oven-safe skillet, heat a tablespoon of olive oil over medium heat. Add the diced onion, bell peppers, and cherry tomatoes. Sauté until the onion becomes translucent and fragrant, about 5-7 minutes. The blend of sweet and savory flavors starts to dance around the kitchen—pure bliss!
Step 3: Add the Spinach
Toss in the spinach and cook until it wilts down, which only takes about a minute. The vibrant green against the golden onions and reds of the tomatoes is truly a feast for the eyes.
Step 4: Prepare the Egg Mixture
In a bowl, whisk together the eggs and milk, seasoning with salt and pepper. I love watching the egg mixture become glossy and light as I whisk—it’s like a promise of the fluffy delight to come.
Step 5: Combine Everything
Pour this egg mixture over the sautéed vegetables in the skillet. Make sure all veggies are submerged. Let the mixture sit on the stovetop for about 2 minutes until the edges just start to set.
Step 6: Bake the Frittata
Transfer the skillet to the oven and bake for about 20 minutes, or until the center has a slight jiggle and a gorgeous golden hue develops on top. The aroma will be intoxicating—I can almost smell it now!
Step 7: Serve
Once it’s cooked, let it cool for a few minutes. Slice into wedges and enjoy warm, or at room temperature. It’s versatile enough for brunch, or even as a light dinner.

Common Mistakes to Avoid
- Not whisking the eggs enough: A well-aerated egg mixture is crucial for fluffiness, so whisk them thoroughly.
- Overcrowding the skillet with vegetables: Too many veggies can make the frittata runny—stick to the ingredient list for balance.
- Skipping the oven step: Attempting to cook the entire frittata on the stovetop can lead to uneven cooking. The oven is essential for that fluffy finish!
Tips and Tricks for Success
- Experiment with flavors: Feel free to add in your favorite herbs like basil or parsley for extra flavor.
- Cheese it up: If you’d like a bit of decadence, sprinkle in some crumbled feta or shredded mozzarella before baking.
- Prep ahead: You can make the vegetable mixture in advance and store it in the fridge for a quick assembly on the day of your brunch event.
Variations
- Swap out spinach for kale or Swiss chard for a different green.
- Use zucchini instead of bell peppers for a lighter texture.
- Add cooked bacon or sausage for a meaty version.
- Incorporate different types of cheese, such as cheddar or goat cheese.
- Experiment with seasonal vegetables, like pumpkin or butternut squash, in the fall.
How to Serve
- Slice into wedges and serve warm for brunch.
- Pair with a side salad for a light dinner option.
- Serve at room temperature for a picnic or potluck.
- Garnish with fresh herbs or a dollop of sour cream for extra flavor.
- Offer with toast or crusty bread to soak up the delicious flavors.

Make Ahead and Storage
- Make Ahead: Prepare the vegetable mixture in advance and store it in the fridge for a quick assembly on brunch day.
- Storage: Store leftovers in an airtight container in the fridge for up to 3 days.
