INGREDIENTS
Egg whites: you can also use whole eggs as well. I recommend using 1 whole egg for every 2 egg whites so you would use a total of 6 whole eggs for this recipe.
Spinach: fresh is best.
Mushrooms: you can use white button mushrooms or baby bella mushrooms.
Shredded cheese: I used Swiss cheese for this recipe but you can also use sharp cheddar, white cheddar, mozzarella, jack and gouda.
Salt and pepper: for flavor.
Garnish: parsley, chives and green onions all make great options.
HOW TO MAKE EGG WHITE BITES
-
PREP MUFFIN PAN: Heat oven to 350 degrees F. Spray a 12 cup muffin pan with non-stick cooking spray and set aside.
-
SAUTE VEGGIES: Heat a medium frying pan to medium-high heat and coat with cooking spray. Add spinach and mushrooms and cook until spinach and mushrooms have reduced and wilted. Sprinkle with a pinch of salt and pepper and stir.
-
ADD INGREDIENTS TO MUFFIN PAN: Divide the spinach and mushrooms into 12 muffin tins. Equally divide the shredded cheese into the 12 muffin pan and then pour the egg whites equally over the cheese. Sprinkle the tops with a small pinch of salt and pepper (optional).
-
BAKE EGG WHITE BITES: Bake for 12-15 minutes, or until the Egg White Bites are set. Serve immediately and enjoy!
ADDITIONAL INGREDIENTS TO ADD TO EGG BITES
You can certainly add more veggies and protein to your egg bites for more flavor depending on your preference. Below are some ideas that can be easily added. These egg bites are totally customizable so feel free to change it up, especially if you make these on a weekly basis like us.
Optional veggies to add: zucchini, bell peppers, sun-dried tomatoes, caramelized onions, kale and peas.
Optional protein to add: cooked bacon crumbles, turkey bacon, cooked sausage and diced ham.
FAVORITE EGG WHITE BITE TOPPINGS
Salsa: red salsa, salsa verde or pico de Gallo would add tons of flavor and spice.
Guacamole or avocado: smash up an avocado and add spoonfuls to the tops of these egg bites. You can also slice or dice avocado for prettier presentation. Guacamole is always a good idea if you want more flavor.
More cheese: the more the merrier, right?
LEFTOVERS
Store Egg White Bites in an airtight container for up to 5 days in the refrigerator. These will last all week so they make an easy grab and go. To warm, place in the microwave for about 20-30 seconds (each microwave temperature varies).
HOW TO FREEZE EGG BITES
Allow the Egg White Bites to cool completely, at least 30 minutes. Place them in a single layer container and flash freeze them for an hour or until they have hardened. Put in a large plastic bag and store in the freezer. Egg bites will store for up to 3 months in the freezer.
To re-heat the Egg White Bites, thaw the bites overnight and place in the microwave to heat for at least 30 seconds. If you don’t thaw overnight you can defrost the egg bite in the microwave then reheat for a few seconds to warm completely. You could also warm the egg bites in a 350 degree oven for a few minutes.

I never really got into buying egg bites at Starbucks but I sure love making my own at home. These contain my favourite flavour combination, too.
They are 100% better when you make them at home. I hope you love them!
Such an excellent and healthy way to start the day. Thank you for sharing!
🙂 enjoy Marta!

When you say 1 whole egg to every 2 egg whites does that mean the 12 egg whites plus 6 whole eggs or 6 of the 12 egg whites are going to be a whole egg?
Hi Tanya, great question! You would only use whole eggs if you didn’t want to use just egg whites. So if you wanted to use whole eggs, the recipe would yield 6 egg bites. Otherwise if you wanted to make these as is, you would use 12 eggs whites and the recipe would yield 12 egg bites. If you wanted to make these bites extra wholesome and higher in protein, you could use both egg whites and whole eggs. Just increase the baking time by a few minutes. I hope that makes more sense. Please let me know if you have any more questions. 🙂
Do these have nutrition facts for calorie counting and macros??

Hi Jasmyne, I just added the calories and nutritional information in the recipe card. I hope this helps and enjoy!
I love this recipe, but I loathe cleaning the muffin pan after. I use a spray but I’m still getting a lot of egg bits on the muffin pan that are really tedious to clean. I tried using a cupcake liner but the liner got stuck to the bites in a strange way.
Any ideas?
Hi Nik, I love that you love this recipe! I know exactly what you mean. I find that silicone muffin cups work really well! You can easily find them on Amazon. I hope that fixes your problem. I’ve attached the link under equipment in the recipe card. Let me know if you have any other questions. Thank you!!
I love this recipe but for some reason the bites turn extremely watery. This happens with freezing/reheating and when I just keep them in the fridge. Any suggestions?
Hi Brandy, I would try to pat out any excess water from the mushrooms and spinach after you’ve sautéed them. They naturally retain a lot of water and could be why your bites seem that way. Please let me know if you have any other questions 🙂
