When I want a make-ahead breakfast that actually keeps me full, these Petite Vegetable Frittatas are my go-to. They are individual, muffin-tin frittatas: an Italian-style baked egg packed with diced bell peppers, zucchini, onion, Parmesan and chives, portioned into a muffin pan so they bake up perfectly handheld. Make a batch on Sunday and you have grab-and-go breakfast (or a protein-packed snack) all week, and they reheat in under a minute. For more easy egg mornings, my Summer Veggie Quiche is the slice-and-serve version when you want something a little more brunchy, my Breakfast Bowls 5 Ways keep weekday mornings from getting boring, and my Spring Brunch Menu is where these frittatas really shine on a table full of friends.

Why I Love This Recipe
I was never a breakfast person until I was in my 30's. Well, unless it came in the form of a jumbo double chocolate chip muffin from Costco!! Do you guys remember those? They are basically chocolate cake in muffin form and VERY on brand. Well, times have changed and now I'm all about a healthy breakfast to kick off the day like these Petite Vegetable Frittatas! Especially as I'm not responsible for feeding 2 small kiddos AND myself - easy is the name of the game.
We go through 2 batches of these Vegetable Frittatas a week! I make them every few days and we just re-heat them every morning in a toaster oven. I've been known to dunk them in salsa, add a dollop of guacamole, or go back to my childhood ways and add a squirt of ketchup!
They're perfect because the last thing I want to do in the morning is make a mess of my clean kitchen! You can make them with any vegetables you have laying around your kitchen, add a touch of cheese and some fresh herbs and you have yourself a perfect breakfast!

Substitutions & Swaps
🥚 The Eggs
- Egg whites - Swap some or all whole eggs for whites for a lighter, lower-fat version; use about 2 whites per whole egg
- A splash of milk or cream - Whisk in a tablespoon or two for a softer, more custardy set
- Liquid egg substitute - Works 1:1 if you are avoiding whole eggs entirely
🫑 The Vegetables
- Spinach or kale - Wilt and squeeze dry first so they do not weep water into the eggs
- Mushrooms - Saute until the moisture cooks off; raw mushrooms make frittatas soggy
- Broccoli or asparagus - Chop small and blanch or saute so they are tender before baking
- Cherry tomatoes - Halve and add a few per cup; their juice is fine in these small amounts
🧀 The Cheese
- Feta - Briny and bold; crumble it in for a Mediterranean spin
- Sharp cheddar - Melty and kid-friendly, the easiest crowd-pleaser
- Goat cheese - Tangy and creamy; dot it on top of each cup
- Gruyere - Nutty and a little fancy for a brunch-worthy version
🌿 Herbs & Mix-Ins
- Scallions or dill - Swap for the chives depending on what is in the fridge
- Fresh basil - Tear it in for a summery, Italian note
- Cooked crumbled bacon or sausage - Add a tablespoon per cup to make them heartier
- A pinch of red pepper flakes - For a little heat in every bite
🍳 Pan & Format
- Silicone muffin pan - The easiest release; the frittatas pop right out with no sticking
- Mini muffin tin - Make bite-size versions for parties; reduce the bake time by about 5 minutes
- One large skillet - Pour it all into an oven-safe pan for a single big frittata; add 10 to 15 minutes to the bake
How to Make
Preheat the oven to 350 degrees. In a large 10 inch skillet, heat the olive oil over medium high heat. Sauté the diced zucchini, onion and red and yellow bell peppers for about 5 minutes until they are slightly soft. Season with salt and pepper.
Spray a regular sized muffin pan with a non-stick spray.
Add the sautéed vegetables to the bottom of a regular sized muffin pan.
In another bowl, whisk together eggs and season with salt and pepper and add the chopped chives and parmesan. Fill the remaining area in the muffin tin with the egg, gently stirring the ingredients together. Bake the Petite Vegetable Frittatas in the oven for 10-12 minutes until the eggs are completely set.
Tips & Tricks
Use a Muffin Tin
- Opt for a non-stick muffin tin or silicone muffin cups to prevent sticking and make removal easier.
Prep and Cook Ingredients in Advance
- Sautéd veggies can be prepped ahead. Store them in the fridge so you can easily assemble the frittatas when you're ready.
Fill and Freeze
- After baking the Petite Vegetable Frittatas, let them cool completely, then wrap each one tightly in plastic wrap or store them in a freezer-safe container. They’ll last in the freezer for 1-2 months.
Reheat Easily
- To reheat, either microwave a frozen frittata for about 1-2 minutes or bake them in the oven at 350°F for about 10 minutes until warmed through.
Underbake Slightly for Reheating
- Cook the frittatas until they're just barely set. This way, when you reheat them, they won’t become overcooked.
FAQ's
What is a frittata?
A frittata is an Italian-style open-faced omelet made by whisking eggs with vegetables, cheese or meat and baking or cooking it slowly until set. Unlike a folded omelet, the fillings are mixed right into the eggs. These petite versions are baked in a muffin tin so they come out individually portioned.
What is the difference between a quiche and a frittata?
A quiche is a savory custard tart baked in a pastry crust, made with eggs and a good amount of cream or milk. A frittata is crustless and uses mostly eggs, so it is lighter and lower in carbs. Frittatas are also faster since there is no dough to make or blind-bake.
Can I make frittatas ahead of time?
Yes, these are built for meal prep. Bake a batch, cool completely, and refrigerate for up to 4 days or freeze for up to 2 months. Reheat in the microwave for about a minute or in a warm oven until heated through.
How do I keep frittatas from sticking to the muffin tin?
Grease the cups generously with olive oil or butter, or use a silicone muffin pan or liners. Let the frittatas cool for a few minutes, then run a thin knife around the edges to release them. A real nonstick coating helps the most.
Can you freeze vegetable frittatas?
Yes, they freeze beautifully, which is why I make a double batch. Freeze them in a single layer first, then transfer to a bag or container for up to 2 months. Reheat straight from frozen in the microwave or a low oven, and underbake them slightly if you know they are headed for the freezer.

Notes
Nutrition Information (estimated)
Are they made in regular muffin tin or min muffin tin?
regular
I've made this several times with a variation of veggies/meats/cheese. Perfect! They're great to take on a picnic. I bring sauce packets from Taco Bell to class it up. Haha!
Making these later but I think it would be helpful if you mentioned spraying the muffin tins-not everyoe might be aware this is necessary.
It is in the directions.
Can prosciutto be added?
sure thing!
Can I make these a day ahead of putting them into the oven? Trying to prep for Christmas!
yes you can prep the liquid mixture. I wouldn't pour into the muffin tins until day of. And be sure to spray them so nothing sticks
These are delicious mini frittatas that are great to have on hand for breakfast, lunch or snacks. They are a great way to use up whatever is left in the veggie drawer. Today I used bell pepper, leeks, zucchini and spinach.
Hi! This is an awesome recipe! Do you store in the fridge and if so for how long? Trying to figure out if this is a week long recipe! Also if we do egg whites whats the ratio? We will add in a yolk or 3 for more flavor 🙂
Thanks!
I keep in fridge for about 4-5 days.
Haven't made it with egg whites to be honest!
Do you have a recipe for egg bites?
These basically are egg bites, no?
Love this recipe! I used a large onion, red bell pepper, and kale. It took about 15-18 min to bake. The William Sonoma gold touch pan is incredible- I’ve made this recipe in a different pan with cooking spray and could not clean it for the life of me, but the gold touch pan requires no spray, and they pop out easily!
What magic makes these pop out of the tin? I’ve tried everything and have now resorted to a silicone tray. Yours look great though….so what am I missing?!?!
i use gold touch sheet pans from williams sonoma that are incredible and very non-stick
Very good receipe
I have made this recipe many times and vary it from time to time....changing the veggies and/or the the type of cheese. They look beautiful at the end of their baking time, but often "fall" after being out of the oven. I often have wondered if you know if there is a reason for this.
Love theses, so tasty. In the video it looked like you placed you muffin tin on a hot stone or baking tray? Is that Recomended?
Thanks. Love your recipe’s
