Crustless, cheesy, rich in flavors and filling, this cheese and tomato quiche is a perfect breakfast meal when you’re following a low-carb diet, vegetarian, gluten-free, keto, or high-protein diet.

Quiche is a kitchen staple that’s easy to make, comforting, and can be good for you. You just need to alter and omit a few ingredients. Then you have a wholesome, healthy meal or even meal prep.

Therefore, quiche can easily be a regular menu item when following a gluten-free or keto diet.

The cheese will be the savory crust instead of using a traditional dough-based crust. Why? Because it will harden, and the bottom will crisp up really nicely.

Most importantly, you won’t even be able to tell the difference! The richness of the cheese surely outdoes the bland, flour-based crust.

Twelve whole eggs will go into this recipe. This allows each serving to have 23 grams of protein.

How to Make Cheese and Tomato Quiche

First of all, preheat the oven and gather the ingredients. The oven will need to be set at 325F.

Step 1. Shred the cheddar cheese with a cheese grater. It’s always best to use a fresh, whole block of cheese. That’s mostly because this is the most cost-efficient option.

Additionally, bags of shredded cheese often have questionable additives that prevent the cheese from going bad and clumping up.

Step 2. Once you have shredded the cheese, spread 1.5 cups evenly into the bottom of your baking dish (12″ x 8″). Make sure that it covers the bottom evenly. Remember, this is going to be your crust.

It’s ok if there are some holes, and the egg mixture might seep through. But you want that crunchy flavor in each bite.

Step 3. First of all, we’ll chop the tomatoes into small pieces. You may want to remove the seeds and pulp from the tomatoes.

This part of the tomato holds a lot of water that might make your quiche soggy. You can reduce this by soaking up some of the liquid with a paper towel while the tomatoes are still on the cutting board.

Step 4. Now, chop the onion into small pieces. Make sure you are using a very sharp knife to avoid any “onion tears”!

Step 5. Then, melt the butter in the microwave.

Step 6. Add the eggs, tomatoes, onions, and cream cheese into a food processor. Then add the seasonings. Process all the ingredients until everything is blended and smooth.

As you are mixing or processing the ingredients, slowly pour in the melted butter.

Step 7. Finally, pour the mixture over the cheese in the baking dish (12″ x 8″).

Step 8. Sprinkle the remaining ½ cup of cheese on top of the egg mixture.

Step 9. Bake the quiche for 45 minutes. The quiche should be firm around the edges and slightly jiggly in the middle.

Now, let the quiche cool before serving. It will fall apart if you try to cut into it too soon. Serve and enjoy! This quiche pairs well with a simple green salad.

What Cheese are Good for Quiche?

There are a lot of great cheese options for quiche. Harder cheese will be easier to shred. Plus, they will have a richer flavor. Some delicious options are cheddar, pepper jack, and gruyere.

Softer cheese will work, too. They might just be harder to mix in evenly. Feta and goat cheese are fun options to try.

Does Quiche Always Have Cheese?

Cheese is a traditional ingredient in a quiche. But that doesn’t mean you have to use it! It’s ok if you want to omit it if you are following a dairy-free diet.

Keep in mind that it might not be as creamy and rich as a quiche that has cheese. You could compensate with other ingredients that add the salty flavor that cheese provides.

Some examples would be adding ham, bacon or simply adding more vegetables.

What Can I Use Instead of Cream Cheese in Quiche?

It’s ok if you don’t have or don’t want to use cream cheese. Here are some cream cheese substitutes for this recipe:

  • Greek yogurt
  • Sour cream
  • Tofu (dairy-free)
  • Ricotta
  • Plant-based cream cheese, almond or cashew cream cheese (dairy-free)

Can You Make It Ahead of Time?

Yes! You can freeze the quiche in containers for up to 3 months. Thaw before reheating and the quiche will be good to eat!
