Different frittata options
You can customize this egg white frittata to your liking with different veggies, protein and even whole eggs!
- Use whole eggs: Instead of egg whites, you can try making this frittata with two cups of whole eggs (around 6-7 eggs).
- Add some protein: This recipe is vegetarian, but you can add some protein to it if you want! It'd be delicious with bacon, turkey sausage or ham.
- Mix up the veggies: Clear out your vegetable crisper and add different veggies like roasted red peppers, mushrooms, kale and more.
- Add some cheese: If you're fine with this frittata containing dairy, feel free to mix in your favourite cheese like shredded Swiss, mozzarella or even goat cheese.
Frequently Asked Questions
I'd recommend using a 9-inch round pan, baking dish or non-stick skillet for this recipe. Make sure you grease the pan really well so that the frittata doesn't stick to the sides!
I find it easier to use a carton of egg whites, but if you prefer using whites from whole eggs, you can definitely give it a try. You'll probably need at least 16 whole eggs for enough whites, but use a measuring cup to ensure you have two cups of whites.
You can eat this egg white frittata either hot or cold. If you want to reheat it, stick it in the microwave for 1 to 2 minutes.
If your frittata puffs up after baking, you likely over-beat the egg whites. Make sure you're only lightly stirring the ingredients together to prevent over-beating the eggs.
This frittata is a full meal on its own, but you can always serve it with some toast or a bagel, some cut-up fruit, a smoothie or a yogurt parfait.
Storing and reheating
After you’ve cooked your frittata, you can store it in the fridge for 3 to 4 days in an airtight container or wrapped in plastic wrap. Store individual serving sizes or the entire frittata in one container.
When you’re ready to enjoy, eat your frittata cold or warm it up in the microwave for 1 to 2 minutes. Serve it with fresh cheese on top, any sauce of your choice, on a bagel or just by itself!
Freezing this recipe
Freeze this egg white frittata for 2 to 3 months in an airtight freezer-safe container. Let it thaw in the fridge overnight then reheat it in the microwave or in the oven for 15 to 20 minutes at 300° Fahrenheit.

5-Ingredient Egg White Frittata {Meal Prep}
Ingredients
- 2 tbsp olive oil or butter
- 1 500mL carton egg whites
- 1 cup cherry tomatoes, sliced in half or 1 red pepper, chopped
- 1 red onion thinly sliced
- 1 cup baby spinach, chopped
- 1/2 tsp each Salt & pepper
Optional add-ins for extra flavour
- 1/2 cup cottage cheese blended with an immersion blender
- 2 cloves garlic minced
- 1 tsp Italian seasoning
Instructions
- Preheat oven to 400 F. Grease a 9×9 round baking dish/cake pan with olive oil or butter, making sure to grease the sides well. Add remaining ingredients, stirring gently with a fork.
- Place baking dish on top of a baking sheet lined with parchment paper just in case a bit of the oil rises above the egg white mixture (optional, but I do this to avoid grease dripping down into the oven as the egg whites rise and cook).
- Bake in the oven for 30-35 minutes until egg whites are firmly set. Remove from oven and slice into 4-5 pieces when cooled. Congrats, you've got breakfast ready for the week!

Desiree says
Made for the first time. Very good. Added chopped mushrooms to the recipe with tomatoe slices on top with some shredded Gruyère cheese. No salt, but did use garlic powder and pepper. It was very good. It’s a keeper.
Taylor Stinson says
I’m so happy you enjoyed!
Dan says
You said something about dinner leftovers for lunch? What are those? I usually eat my dinner and my wife’s. Thanks for recipe ideas. Sounds delicious
Taylor Stinson says
Hey Dan – you just make dinner (any recipe) and then enjoy the leftovers for lunch. But you gotta stop eating your wife’s dinner too LOL! Here’s a selection of some of my fave recipes for that purpose in case you’re interested: https://thegirlonbloor.com/52-healthy-quick-easy-dinner-ideas-for-busy-weeknights/
Kathryn Adams says
How big is the round pan/baking dish that is needed. Is it 10”, 12”, etc? I want to make this for company but want it to turn out perfect. Could you tell me the width you use? Thanks
Kathy
Taylor Stinson says
Hi Kathryn! It’s a 9 inch pan 🙂
Judy says
Can I make this frittata in a cast iron pan and how many inches across would suit the recipe? Thanks. Judy @Bloor and Manning
Taylor Stinson says
Hi Judy – I have never tried this with a cast iron skillet and I’m not sure how well it would work because you’d have to grease it very well, I imagine the egg would really stick to it. Wish I could advise better!
Kara says
I make a mini version in my 5 in cast iron pan using 3 whole eggs all the time and I’ve never had an issue with it sticking. I’ve also done it in my 16 in cast iron using a dozen eggs. My pans are well seasoned and I just coat the whole inside of the skillet with olive oil before adding the eggs, then veggies. I cook it on medium on the stove top for a few minutes to let the bottom set some then stick it in my preheated oven at 350. If it’s the small skillet it only needs 15 min. 25 to 30 for larger. Only time I had an issue with it sticking was when I got distracted and left it in too long.
Helen says
Hello,
I’m baking this now, but when I put all the ingredients in myfitnesspal, my nutritional value is less than yours for 4 servings. I get 130 calories, 1.9g carbs, 6.9g fat and 12.9g protein. Are your measurements through myfitnesspal? Thanks.
Taylor Stinson says
Hi Helen – I don’t use myfitnesspal, I use a built in plugin that allows me to calculate approximate values. That said, anytime you calculate nutritional info it is a best estimate. Different programs will give different values for different ingredients. What you calculated is only 50 calories off so you can assume it’s around 130-180 calories per serving.
Jackie Brown says
I prefer whites from whole eggs. How many do I need for the recipe?
Taylor Stinson says
Hi Jackie – I unfortunately have not made it using whites from the eggs. You may need to still use the measuring cup and just keep adding the whites once separated from the yolks until you reach 500mL, or 2 cups. From a quick Google search I’m seeing you would need 16 eggs but I can’t verify how accurate that info is. Hope that helps!
Bob says
I made this one today. I topped this with 60 g of herb and garlic cheese after it was cooked and put it under the broiler for 30 seconds or so. It is really delicious.
