Harvest Vegetable Frittata

There’s something truly comforting about a warm, colorful frittata fresh from the oven, especially when it’s packed with the best of the season’s harvest. This Harvest Vegetable Frittata is a vibrant, protein-rich dish that celebrates the bounty of fresh vegetables and creamy feta cheese, making it a perfect meal for breakfast, brunch, or even a light dinner. Using eight large eggs as the base, it’s hearty enough to satisfy but light enough to feel nourishing. Whether you’re feeding a crowd or just want something wholesome and simple, this frittata is a winner.

Why This Harvest Vegetable Frittata Stands Out

What makes this Harvest Vegetable Frittata truly special is the harmony of fresh, crisp vegetables combined with the creamy tang of feta and the fluffy texture of perfectly cooked eggs. Unlike some frittatas that can be heavy or dense, this one strikes the perfect balance—light yet filling, with a beautiful medley of colors and flavors that scream autumn harvest. The inclusion of spinach, zucchini, bell peppers, and cherry tomatoes adds layers of sweetness and earthiness, while the feta cheese brings a subtle saltiness that enhances the overall taste.

Another standout feature is the simplicity of preparation. Using just one pan and straightforward steps, this recipe fits seamlessly into busy mornings or relaxed weekend brunches. The olive oil adds a gentle richness without overpowering the fresh ingredients. Plus, garnishing with fresh herbs like basil or parsley elevates the dish with a burst of freshness and aroma.

If you love dishes that combine wholesome ingredients with ease and elegance, this Harvest Vegetable Frittata is about to become a staple in your kitchen.

Harvest Vegetable Frittata — Do This Next

Step 1: Prep Your Vegetables

Start by washing and chopping all your vegetables. Dice the bell peppers, small onion, and zucchini into roughly uniform pieces for even cooking. Chop the spinach and halve the cherry tomatoes. Having everything ready to go will make the cooking process smooth and stress-free.

Step 2: Sauté the Vegetables

Heat the olive oil in your oven-safe skillet over medium heat. Add the diced onion first and sauté for about 3 minutes until it starts to soften and turn translucent. Then, add the bell peppers and zucchini. Cook for another 5 minutes, stirring occasionally until the vegetables are tender but still vibrant in color. Finally, toss in the chopped spinach and cook just until wilted—about 1 to 2 minutes. Season all the vegetables lightly with salt and pepper.

Step 3: Whisk the Eggs and Milk

While the vegetables are cooking, crack the eggs into a mixing bowl. Add the milk, a pinch of salt, and freshly ground pepper. Whisk until the mixture is smooth and slightly frothy. This step helps incorporate air, ensuring your frittata will be fluffy.

Step 4: Combine and Add Feta

Pour the egg mixture evenly over the sautéed vegetables in the skillet. Sprinkle the crumbled feta cheese on top. Don’t stir after this point—allow the eggs to cook undisturbed so the frittata can set properly.

Step 5: Cook on the Stovetop, Then Finish in the Oven

Let the frittata cook on medium-low heat for about 5 minutes. The edges will start to set, but the center will still be runny. Transfer the skillet to a preheated oven at 375°F (190°C) and bake for 12-15 minutes, or until the middle is fully set and slightly golden on top.

Step 6: Garnish and Serve

Remove the frittata from the oven carefully using oven mitts. Let it cool for a few minutes before slicing. Garnish with fresh herbs like basil or parsley to add a fresh burst of flavor and a beautiful pop of green. Serve warm, alongside your favorite breakfast sides or a crisp salad.

Make It Your Way

• Add roasted sweet peppers for a smoky twist and extra sweetness.
• Substitute the feta cheese with goat cheese or a mild mozzarella if you want a creamier texture.
• Incorporate other seasonal vegetables like mushrooms or asparagus for variety.
• For a dairy-free option, swap the milk for almond or oat milk and omit the cheese.
• Try mixing in a pinch of smoked paprika or ground cumin for a subtle spice boost.
• Serve the frittata with a side of Harvest Salad With Butternut Squash to keep the harvest theme going strong.

Avoid These Mistakes

• Overcooking the vegetables: If veggies are too soft or mushy before adding eggs, the frittata can become watery.
• Using high heat: Cooking on too high a heat can brown the eggs too fast, leaving the center undercooked.
• Skipping the oven finish: The stovetop alone won’t set the frittata evenly; the oven ensures a perfect texture.
• Not seasoning properly: Salt and pepper are essential to bring out the natural flavors of the vegetables and cheese.
• Using a non-oven-safe skillet: Make sure your pan can go from stovetop to oven safely to avoid accidents or damage.

Meal Prep & Storage Notes

This Harvest Vegetable Frittata is fantastic for meal prep. You can make it ahead and store individual slices for easy grab-and-go breakfasts or lunches.

• Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat in the microwave or oven until warmed through; avoid overheating to keep the eggs from becoming rubbery.
• For longer storage, you can freeze slices wrapped tightly in plastic wrap and foil. Thaw overnight in the refrigerator before reheating.
• If you plan to meal prep, consider undercooking the frittata slightly before refrigerating; it will finish cooking perfectly when reheated.

Your Questions, Answered

Can I use other types of cheese in this frittata?

Absolutely! While feta adds a tangy creaminess, you can substitute it with goat cheese, mozzarella, or even a sharp cheddar depending on your taste preferences. Just be mindful of the saltiness as some cheeses can be saltier than feta.

Is it necessary to cook the frittata in the oven?

Cooking the frittata in the oven helps it set evenly and develop a beautiful golden top. You can finish it on the stovetop with a lid, but the texture might be less uniform and the top won’t brown as nicely.

Can I make this recipe vegan-friendly?

To make a vegan version, replace the eggs with a chickpea flour batter or scrambled tofu, swap the milk for a plant-based alternative, and omit the cheese or use a vegan cheese substitute.

What’s the best way to reheat leftover frittata?

Reheat leftover frittata slices in the microwave for 30-60 seconds or in a preheated oven at 350°F (175°C) for about 10 minutes. Cover loosely to prevent drying out. This preserves the texture and flavor best.
