This recipe makes six very generous servings.

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.

This is a great amount of protein for an individual serving while following a keto or low carb diet.

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: Prepare the Cheese Base

Then, 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. Buying shredded cheese is more expensive.

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

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 2: Prepare the Egg Mixture

Now, prepare the rest of your ingredients.

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.

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

Then, melt the butter in the microwave.

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.

It’s ok if you don’t have a food processor. You can always look for one another time.

They are a great kitchen tool that has a lot of uses. This food processor is a good affordable option.

For now, a whisk will work just fine. You will want the cream cheese to be at room temperature so that it mixes easily.

You also might want to cut the tomatoes and onions into smaller, equal-sized pieces as well. This will ensure the same smooth consistency as if you were using a processor.

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

Step 3: Prepare the Quiche

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

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

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.

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.
