How to Make Keto 3-Cheese Mini Quiches

This is just a quick overview of how to make the keto-friendly quiches. For the recipe in detail, scroll to the recipe card at the end of the post.

Prepare veggies by sauteeing the onion and red bell pepper in olive oil, then adding the frozen and drained spinach and cooking until the mixture is no longer moist. TIP: To drain the spinach, I usually hold the spinach in my hand and give it a good squeeze to drain it. This is far more effective than using a towel to drain out the moisture.

Add the shredded mozzarella and cheddar, salt and pepper, and vegetable mixture to a bowl. Mix to combine.

    • Hi Cara! This recipe doesn’t contain mushrooms. Any chance you were looking at my Keto Flu Soup recipe? If so, the easiest substitute would be chopped cauliflower, or — easier yet — cauliflower rice. If using cauliflower rice, you’ll have to reduce the cook time in Step 1 so you don’t burn the cauliflower rice.

    Made these today with just Mozza cheese, yellow pepper, what I had left of an onion, and fresh spinach. They taste great! Kids were eating them too – success!

  • Hi I’m doing a wine tasting party and wondering if I can make ahead and then warm up. I’m taking them to a friend’s house to have party. Thanks

    I made this in a 8×8 glass pan. I added 1/2 tsp dry mustard, 1/4 tsp fresh thyme, 1/2 c cubed ham, 1/4 cup half n half. . I cut the cheeses back to 1cup each and could have done 3/4 cup each. I also sautéed fresh spinach with my onions and peppers. Absolutely delicious. Cut into small squares, wrapped in wax paper and into the freezer. 9 servings. Great with a keto muffin

    • Hi Nancy! You definitely can. You’ll likely need to bake it longer since you’re baking a larger surface area, so check it at 25 minutes, 30 minutes, and every 5 minutes after that until it’s fully cooked. Enjoy!

    Love these Keto mini quiches! The cheese quiches taste great and are simple to make. I like that I can make a batch and freeze some for an easy snack. My three year old tried one and now it is all he wants for breakfast which is a healthy plus with all the vegetables and cheese in them.
