Ingredients for Vegetable Frittata
Oh, the beauty of a frittata is how simple the ingredients are! I always start by separating them into two groups – the egg base and the veggie mix-ins. Here’s what you’ll need for the most delicious vegetable frittata (and don’t worry – these measurements aren’t set in stone, except for the eggs – those are important!):
For the Frittata Base
- 6 large eggs: The star of the show! Don’t skimp here – they create that perfect fluffy texture.
- 1/4 cup milk: Any kind works, but whole milk makes it extra creamy. Water can substitute in a pinch.
- 1/2 tsp salt: More if you’re like me and love savory breakfasts.
- 1/4 tsp black pepper: Freshly ground is best for maximum flavor.
For the Vegetables
- 1 tbsp olive oil: For sautéing those veggies to perfection.
- 1/2 cup diced onion: Brown or yellow – your choice! I prefer them small but still with some texture.
- 1 cup diced bell pepper: Mix colors for a pretty presentation – I’m partial to red for sweetness.
- 1 cup packed spinach: Roughly chopped – it wilts down so don’t be shy!
- 1/4 cup crumbled feta cheese: The salty kick is divine! If you want other ideas, check out this veggie-packed egg muffin recipe for inspiration.
See how simple that is? And the best part – almost all these ingredients are probably in your kitchen right now. That’s why I love this recipe so much – minimal fuss, maximum deliciousness!
How to Make Vegetable Frittata
You won’t believe how easy it is to whip up this vegetable frittata – I’ve made it so many times I could probably do it with my eyes closed (though I don’t recommend trying that!). The key is getting everything prepped before you start cooking. Here’s how I make sure mine turns out perfect every single time.
Step 1: Prep the Eggs and Vegetables
First things first – crank that oven to 375°F (190°C). While it’s heating, let’s get everything ready. Grab your largest bowl and whisk those eggs like you mean it! I do about 30 vigorous strokes – you want them light and frothy. Add the milk, salt, and pepper, and give it a few more whisks until everything’s combined. The mixture should look pale yellow and slightly bubbly – that’s how you know you’re on the right track.
Now for the veggies! Heat your olive oil in an oven-safe skillet over medium heat. I like to test if it’s ready by flicking in a tiny piece of onion – if it sizzles, you’re golden. Add the onions and bell peppers, stirring occasionally. Watch them carefully – you want them softened but not browned (about 5 minutes does the trick). Toss in the spinach last – it wilts almost instantly, which still amazes me every time!

Step 2: Combine and Bake
Here comes the fun part! Pour that beautiful egg mixture right over your sautéed veggies. The key here is pouring slowly – I go in a circular motion to distribute everything evenly. Sprinkle the feta cheese on top (it’ll sink a bit, and that’s okay!). Now don’t touch it! Let it cook undisturbed for 3-4 minutes until you see the edges starting to set – they’ll pull away slightly from the pan like they’re giving you a little wave.
Now transfer the whole skillet to your preheated oven. This is where the magic happens! Bake for 12-15 minutes – you’ll know it’s done when the center is just set (no jiggling!) and the top gets that gorgeous golden hue. Pro tip: If you’ve got leftover veggies, check out my spinach feta breakfast quesadilla recipe for another delicious way to use them up!
Let it rest for 5 minutes before slicing – I know it’s hard to wait, but this helps it hold together beautifully. And there you have it – breakfast (or lunch, or dinner!) perfection in under 30 minutes. See? I told you it was easy!

Tips for the Perfect Vegetable Frittata
After making this vegetable frittata more times than I can count, I’ve picked up some tricks that make all the difference! First – and this is non-negotiable – use an oven-safe skillet. I learned that the hard way when I melted a plastic handle (oops!). Don’t overcook the eggs – pull it out when the center just barely jiggles. And please, let it rest for 5 minutes before slicing – it’s torture to wait, but it won’t fall apart this way.
My secret weapon? Mushrooms! I sauté them with the onions for extra umami goodness. Also, if your veggies release water while cooking, drain them slightly before adding the eggs – nobody wants a soggy frittata. And here’s a fun one – try sprinkling everything bagel seasoning on top before baking for extra crunch and flavor!
Variations for Vegetable Frittata
Oh, the possibilities with a vegetable frittata are endless! I love playing around with different combinations – it’s like a blank canvas for breakfast. Swap the feta for sharp cheddar if you’re craving something richer, or go creamy with goat cheese (my personal favorite). Out of bell peppers? Try zucchini or cherry tomatoes instead – they add such lovely texture. And for my meat-loving friends, crispy bacon or diced ham make fantastic additions.
Need a dairy-free version? Simply skip the cheese or use your favorite plant-based alternative. The beauty of this recipe is how forgiving it is – I’ve never met a veggie that didn’t work in a frittata!
Serving Suggestions
Oh, you’re going to love how versatile this vegetable frittata is for serving! My absolute favorite way? Sliced warm with crusty sourdough toast – the perfect combo of creamy eggs and crunchy bread that makes me weak in the knees every time. For brunch, I’ll serve it with a simple green salad dressed with lemon vinaigrette to cut through the richness. And if I’m feeling fancy, I’ll add a side of Greek yogurt parfait for a complete meal that satisfies every craving.
Leftovers (if you have any!) are just as delicious – I’ll grab a cold slice straight from the fridge for a quick protein boost. To reheat, pop it in the microwave for 30 seconds or warm it gently in a skillet to bring back that perfect texture. Pro tip: It also makes amazing breakfast sandwiches when tucked between English muffins – my kids beg for these on school mornings!

Nutritional Information
Okay, let’s talk numbers – but don’t stress! One serving of this veggie-packed frittata gives you about 180 calories, 12g of protein (hello, muscle fuel!), and just 8g of carbs. The 12g of fat comes mostly from those gorgeous eggs and feta – the good kind that keeps you full! Now, here’s the thing – these numbers can change based on your exact ingredients. Used more cheese? Added bacon? Your numbers will be different than mine, and that’s completely fine. That’s the beauty of cooking at home – you make it your own!
FAQ About Vegetable Frittata
I get so many questions about my go-to vegetable frittata recipe – and honestly, I love chatting about it! Here are the ones that come up most often from friends and family (and yes, I’ve tested all these scenarios myself!):
Can I freeze vegetable frittata?
Absolutely! Let it cool completely first, then wrap individual slices tightly in plastic wrap and foil. They’ll keep beautifully in the freezer for up to 1 month. To reheat, I pop them straight from freezer to toaster oven – about 15 minutes at 350°F brings them back to life without drying out.
Can I use frozen vegetables in my frittata?
You sure can, but here’s my trick – thaw and drain them first! Frozen veggies release extra water when cooking, which can make your frittata soggy. I spread them on paper towels and press gently to remove excess moisture. My favorites are frozen spinach and pepper blends – total time savers on busy mornings!
How long does leftover frittata last in the fridge?
In my house? Maybe 5 minutes because it disappears so fast! But seriously, stored properly in an airtight container, it stays fresh for 3 days. The texture changes slightly – it gets denser but is still delicious cold or gently reheated. I actually love it straight from the fridge for a quick protein boost!
Can I make this without dairy?
Of course! Just skip the milk (or use water) and omit cheese. I’ve made it this way for my lactose-intolerant niece and she adores it. For extra creaminess without dairy, try adding a splash of unsweetened almond milk – it works better than you’d think!
