Variations for your quiche

The base of this recipe is low-sodium, meat-free, and keto-friendly. But you can certainly play around with the ingredients based on your tastes and dietary preferences!

Want to add more veggies or swap some around? Broccoli, asparagus, bell peppers, yellow squash, and zucchini are all popular options!

I recommend using low-sodium cheese like gruyére or Swiss. However, if you’re not watching your sodium, you’re welcome to use cheddar, Parmesan, mozzarella, or any cheese you prefer.

Want to add some meat? Bacon, sausage, and even shredded chicken would all be delicious. These ingredients will definitely add some sodium, so be sure to adjust based on your goals.

Storage

Quiche is a great way to meal-prep breakfast! You can store leftover quiche in an airtight container in the refrigerator for up to 3 days.

When you’re ready to enjoy, I recommend reheating in the oven. Place in the oven at 350°F until the quiche is warmed through.
