Why you’ll love it

Goodbye boring breakfasts- this simple egg white quiche is so flavorful, absolutely delicious, and perfect for your rotation of healthy breakfast ideas. With three kinds of cheese, it has the perfect amount of creamy cheesy flavor balanced out by the flavors of spinach, red peppers and green onion.

It’s also incredibly easy to make. Make-ahead egg bakes like egg bites and quiches are the perfect breakfast option because you can prep them ahead of time and then reheat all week for easy breakfasts. It’s also great for a fun brunch option!

If you’re someone who struggles with busy mornings, you’ll love this one.

It’s high protein! One generous serving of this easy breakfast recipe packs 24 grams of protein, so it’s definitely going to keep you full!

Let’s get into how to make this red pepper spinach egg white quiche!

Ingredients

1. Egg whites: Egg whites are our main ingredient, of course! You can either crack whole eggs and just use large egg whites, or buy a carton of liquid egg whites ready to go from the grocery store. Not sure what to do with leftover egg yolks? Here are some ideas!
2. Cottage cheese: Even if you’re a cottage cheese hater, I promise, you won’t even know there’s cottage cheese in this recipe. The cottage cheese takes the place of heavy cream and adds creaminess and protein and becomes nearly undetectable when you bake it.
3. Fresh spinach or kale: Spinach or kale will both work for this recipe, so whatever you have on hand is fine. You can also use regular greens or baby greens like baby spinach.
4. Red bell pepper: I like to use fresh red bell peppers but you could also use jarred roasted red pepper if you prefer.
5. Green onion (spring onions): Green onion adds a milder onion flavor than traditional onions, but if you need a swap you can use sweet onion, white onion or yellow onion.
6. Monterey jack cheese: Monterey jack cheese is my favorite for this quiche but you can use whatever shredded cheese you have on hand- cheddar, mozzarella, or swiss cheese would all work great too.
7. Feta cheese: Feta cheese adds just the right amount of salty tangy flavor to the quiche. You could also use goat cheese or parmesan cheese in place of it.
8. Salt & black pepper

Step-by-step instructions

1. Preheat oven to 350 degrees and prep a round 8″ baking dish or pie dish by spraying with cooking spray or oil.
2. In a small sauté pan, heat olive oil on medium heat and sauté bell pepper, spinach and green onion for 3-4 mins. Transfer to a small bowl and allow to cool.

3. In a large bowl, add egg white, cottage cheese, monterey jack cheese, feta cheese, salt, and pepper. (If you’re planning to use a tabletop blender, add these ingredients directly to a blender)

4. Using an immersion blender, blend for 30-60 seconds until fully combined and smooth. (If using a tabletop blender, blend on high until smooth)

5. Mix in cooled veggies and pour egg mixture into the prepared baking dish

6. Bake in the oven for 35-45 minutes. The quiche will be golden brown and firm in the middle when finished.

Recipe FAQ

Can I add a crust to this quiche?

Sure! If you don’t want a crust-less quiche you can go ahead and use a homemade pie crust or a regular pie shell crust like a store-bought pie crust as you would for a traditional quiche. Just be sure to bake the crust ahead or use a pre-baked crust.

Can I use whole eggs instead of egg whites?

Yes, if you prefer, you can use whole eggs instead. 1.5 cups of whole eggs is roughly 7 eggs. You can also do a combination of eggs and egg whites, as long as the total volume is 1.5 cups.

Serving suggestions

For a complete and balanced breakfast, I recommend serving this egg white quiche with a good source of complex carbohydrates like whole grain toast, a whole grain English muffin or bagel, some breakfast potatoes and/or some fruit!

How to store

You can store this quiche in an airtight container in the fridge for up to 4 days.

Can I add other vegetables?

Absolutely, this is a great way to use up any fresh vegetables or fresh herbs that you have in your fridge that are about to go bad. Just follow the recipes as written. Cherry tomatoes or broccoli would be great additions. The texture may be slightly different depending on the vegetable but will still work!
