Even if you don't know how to bake a quiche, this recipe and the helpful tips will tell you everything you need to know. It's super easy to customize the cheese mixture and make a low-carb recipe you adore.
Ingredients
There are two parts to this cauliflower crust quiche. I'll share a bit of information about what I used in both the crust and the filling.
Cauliflower crust
You'll need a food processor to make this crust. Here's what I used in my crust.
- Cauliflower Florets - I used an entire head of cauliflower
- Mozzarella Cheese - Fresh cheese is best
- Parmesan Cheese - Grate your cheese at home to avoid hidden preservatives and carbs.
- Egg - This is the binding agent that holds the crust together.
- Salt - I always add salt to my recipes because it enhances all the other flavors.
- Garlic Powder - Minced garlic can also work.
Quiche filling
For the filling, I made a basic bacon and cheese filling. This will be what I'll be eating for breakfast most of the week. It's going to be perfect for taking along to work.
- Bacon - Try to use low-sodium, sugar-free bacon.
- Cheddar Cheese - Shredded cheese is one of the other binding agents in this filling.
- Parmesan Cheese - Grate your cheese at home; parmesan cheese has an incredible and earthy flavor that enhances this quiche.
- Heavy Cream - Full-fat heavy whipping cream is best for this quiche.
- Eggs - This is the main ingredient in quiche. Use your favorite type of eggs.
- Water - You just need a little bit to thin out the filling.
- Salt - Just add a dash to bring out all the flavors.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
Tips
- Bake the crust completely. Bake it until it's golden all over and not just on the edges.
- Broil the crust first. This is another way to pre-cook the crust and make it extra crispy.
- Frozen riced cauliflower will save you time. Grab some from the store, and make sure you remove as much water as possible.
Instructions
Here's how to make your cauliflower crust quiche easily in the oven. All the instructions for this casserole recipe are in the printable card at the bottom of this post.
Rice the cauliflower
Use a food processor to finely chop up cauliflower florets. This cauliflower mixture will become your crust.
Make the crust
To ensure the crust wasn't mushy, I squeezed out most of the water from the cauliflower after it was cooked. To do this, I used cheesecloth. It's impossible to remove all the water, but I did end up getting a lot of it out.
Add all the crust ingredients together and then press it into a tart or pie plate.
Bake it, and then let it cool on a wire rack.
Make the quiche filling
First, sprinkle the bacon, cheddar cheese, and parmesan cheese directly onto the baked pie crust.
Then, combine the eggs, cream, water, and salt. Pour this egg mixture and cheese mixture into a tart pan or prepared pie dish.
Bake cauliflower crust quiche
Bake the quiche for about 45 minutes. Allow it to cool down completely before you slice into it.
️ Serving suggestions
This cauliflower crust quiche is a high-protein breakfast recipe. Serve it with some low-carb rainbow pancakes for a really fun breakfast!
Or, serve it with other Easter recipes, like a cheesy ham and cauliflower casserole.
It will also taste amazing with some of my favorite cauliflower recipes, such as bang-bang cauliflower or cheesy broccoli cauliflower soup with sausage.
Variations
This cauliflower crust quiche is perfect if you love quiches. Here are some fun ways to change it up.
- Sprinkle some feta cheese in with the shredded cheese. You can also change the filling by adding some diced ham and baby spinach. Add bell pepper if you want it to have more color and nutrition.
- For a lighter quiche, make it with egg whites only. When it's finished baking, top it with green onions.
- For those of you who prefer a more traditional-style crust, I'd use a savory pie crust similar to the one I used in this key lime pie. You'd just need to omit the sweetener in the crust.
- I've also been buying lower-sodium bacon. Low-sodium bacon is what I prefer now because it doesn't leave me thirsty all day.
- You can also leave out the cauliflower crust completely and make a crustless bacon cheddar quiche. That's probably the best way to go if you are in a low-carb induction phase.
FAQs
Before we get to the printable recipe card, here are some questions people often ask about how to make this cauliflower crust quiche.

Hi Lisa ~ Just realized what I did about the bacon. It is 1 lb. (16 oz) uncooked! I was weighing it after it was cooked. Never mind!!
vanessa ross
Hi ~ In the middle of making this right now! The recipe calls for 16 oz of bacon. I weighed 10 slices - a full package of thick cut - and I'm only at 6 oz. Does the recipe really call for a pound of bacon??
Laurie Pippert
Delicious! Here are a few insights I gained from making this recipe for the first time.
I put the crust under the broiler for about 2 minutes to get it browned. It worked like a charm.
The instructions indicate a total cook time of 23 minutes but that is not accurate. The crust cooks for 15-18 minutes, and the quiche cooks for 40-45 minutes. Therefore, the total cooking time is between 55 - 63 minutes so you'll need to have a bit more time to prepare and to wait until it's ready to eat.
I also used frozen riced cauliflower which saved me a bit of time with preparation.
Lisa
Thanks for catching that about cooking time. And, the broiler tip is perfect.
Christina
I made this last night with some modifications because I am vegetarian. Instead of bacon I used chopped spinach, mushrooms and scallions. It was really good. The deletion of bacon also brought the calories way down.
Lisa
Definitely an option for those who want a meatless meal!
Patricia Conrad
great recipes
Lisa
Thanks Patricia!
Sue
What Bacon did you use from Walmart? Thanks!
Lisa
I do not recall the brand, but it was a low sodium one.
Adel
If you are near a Costco, their low sodium bacon is sugar free as well!

Hi Lisa, this recipe sounds good. I haven't tried using a cauliflower crust for a quiche before and I am intrigued. I just have one question. How many people does this serve? Maybe I missed it somewhere? Thanks for the recipe.
Lisa
I'm the one who missed inputting the servings. Oops! Thanks for catching that!
Janell
And the servings is??????
Lisa
At the top of the recipe card... 8 servings.
Kathleen Dussault
Is your nutrition information for the entire pie?
Lisa
It's for a 1/8 slice of the pie.
