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!

Comments & Reviews
Allyson says
Do you eat the leftovers hot or cold?
Taylor Stinson says
Hey Allyson! You can do either 🙂 I prefer to microwave for a couple of minutes but you can definitely eat cold
Chef Enjoy says
Tried this and loved it. Made a few tweaks, and have made at least a dozen of these!! A few notes and variations:
– An option is to use 1/2 whole egg and egg white. (I used 4 or 5 each)
– Use roasted vegetables (asparagus, tomatoes, zucchini, peppers, even sweet potatoes,)
– Use some sautéed onion, garlic or shallots to add flavor
– Use glass pie pan, lined with parchment for the easiest cleanup!
– They do freeze well, but I agree the all white ones get a bit rubbery. (Not the case with the 1/2 whole and white)
– Make one on Sunday, divide in five, refrigerate, and you have breakfast “to go” for the week.
Enjoy, as is or with any of the variations!!
Maggie Unzueta says
It looks incredibly delicious. I wish this were in front of me.
Lindsay says
Could you do this in a cast iron skillet? Would you grease it at all?
Taylor Stinson says
You could likely make it in a cast iron skillet – I would definitely grease very well first!
Megan says
Hi Taylor,
Can you freeze this?
Cheers,
Megan
Taylor Stinson says
You can definitely freeze it Megan! But I would recommend eating it fresh because I’ve heard cooked egg whites can get a bit more rubbery in the freezer. But if a slight compromise in texture is fine with you then you can go ahead and try storing it in the freezer!
Anthony says
Hi. I wanted to know what was a good size pan to use dimension wise.
Taylor Stinson says
Hey Anthony! A 9 inch round pan will work 🙂
Kristen says
So Good! I added a little bit shredded cheese and goat cheese and it’s was so yummy!
Taylor Stinson says
Ooooh great idea! Glad you liked it Kristen!
Amy says
I am wondering if i wanted to use whole eggs, do you know how many i would use?
Taylor Stinson says
Hey Amy! A safe bet would be 8-10 eggs (no egg whites, just the eggs) Hope that helps 🙂
Colleen Volcjak says
I made this about 2 weeks ago and loved it. I actually sautéed some mushrooms and added it in. Delicious! I am making it again for this week and I am adding some crushed red pepper and a little cheese to the pot! What I did not notice is the recipe called for 1 cup of spinach where I added a whole bag of baby spinach! But hey, I love spinach anyways! Love your recipes!
Taylor Stinson says
Aww thank you so much Colleen, that’s awesome to hear you’ve been able to customize this frittata with such great results!!! I am obsessed with mushrooms so I will have to try that too 🙂
ShI says
Can I make this overnight
Monica Palacios says
Hello, regarding this recipe: “My Favourite Meal Prep Egg White Quiche”, it looks wonderful! I was wondering if I could do it in my INSTANT POT? If so, in which setting and for how many minutes? Thank you very much for your help!
Taylor Stinson says
Hey Monica, unfortunately I haven’t tried it in the Instant Pot so I couldn’t tell you. Sorry about this – maybe I’ll make an Instant Pot version in the future!
