This keto quiche doesn‘t have a traditional flour-based crust. Instead, the base is extra flavorsome and good for you.

Here we‘re using zucchini, pepperoni, and cheese to create the base we want. It‘s not crusty but way more nutritious!

Zucchini has a lot of health benefits. It‘s full of antioxidants and fiber.

On the other hand, pepperoni will give this quiche a unique, smoky flavor. A pepperoni is a great option when following a keto diet.

It contains protein, negligible carbs, and healthy fats. And who doesn‘t love cheese? Cheese is completely fine in moderation!

It‘s a great addition to this recipe and a necessity for a classic quiche.

How to Make Keto Quiche with Zucchini and Pepperoni

Get your ingredients and let‘s start!

Ingredients You‘ll Need:

  • pepperoni
  • zucchini
  • large eggs
  • cheddar
  • heavy cream
  • garlic powder
  • Italian seasoning
  • salt & black pepper

Step-by-step Instructions

Pre-heat the oven to 375F (190C).

Grate the zucchini by using a cheese or vegetable grater. Make sure to keep the skin on.

The skin has most of the nutrients and is extremely high in fiber. That fiber is going to help you stay full longer.

Next, you are going to want to get all of the moisture out of the zucchini.

There are a few ways you can do it. You can squeeze out the water with your hands, towel, or cheesecloth.

This is a crucial step. The bottom of the quiche will get soggy if you don‘t get rid of all of the extra moisture.

Now mix the zucchini, cheese, and pepperoni in a bowl.

Next, grease your baking dish with oil. Use either a glass or ceramic baking dish.

Olive oil or avocado oil are great oils to keep in the kitchen. Feel free to use an oil spray as well.

Take the zucchini mixture and spread it evenly on the bottom of the pan. Press it down so that it‘s nice and compact.

How to Store the Keto Quiche

This quiche makes great leftovers! You can store the quiche in a few different ways.

Always store leftovers in an air-tight container. Use glass containers to keep the quiche fresh for longer. These are the ones I use.

The quiche will stay fresh for 3-4 days in the refrigerator.

Can You Freeze Homemade Quiche?

You can also freeze the leftovers. In fact, the quiche will last for 3-4 months in the freezer.

Using the same air-tight containers will be fine. They shouldn‘t let any moisture in.

Tip: Make twice the amount when preparing this recipe. Have one dish now and freeze the other one for an easy weeknight meal.

For storing, a baking dish like this one would work great. You can bake in the dish and then simply put a lid on it.

Afterward, just remove it from the freezer the night before and thaw it in the refrigerator.

The quiche is best served warm, but not piping hot. Also, you can heat it up in a microwave or a countertop toaster oven.

Feel free to also eat it at room temperature or cold.
