Keto Quiche Recipe

What Is A Quiche?

A keto quiche is a savory egg tart with a crust, filled with a creamy mix of eggs, veggies, cheese, and sometimes meat — kind of like a fancier breakfast casserole or frittata! The big difference between a quiche and a frittata? Quiche has a crust and bakes in the oven, while frittatas are crustless and start on the stove. (You can read more in my vegetable frittata post!)

Ingredients & Substitutions

Here I explain the best ingredients for my broccoli cheddar quiche recipe, what each one does, and substitution options. For measurements, see the recipe card.

For the Pie Crust:

You can make this keto quiche with almond flour or coconut flour crust — I usually go with almond because I love the flavor for savory dishes like this. But if you need a nut-free option, coconut flour works too! And if you want to skip the crust altogether, no problem — just make my keto crustless quiche instead.

For The Filling:

• Cooked Veggies – I sauteed broccoli for this broccoli cheddar version, but honestly, any cooked veggies you’ve got will work. I think roasted ones give the best flavor, but steamed or stir-fried is fine, too. Try asparagus, bell peppers, cauliflowe, kale, mushrooms, onions (caramelized are my fave!), spinach, or zucchini — it’s super flexible.
• Optional Meat – I skipped the meat this time, but feel free to toss in whatever cooked meat you have on hand. Bacon, sausage, ground beef, ham, salami, prosciutto — it all works!
• Olive Oil – I use it to sauté the veggies, but avocado oil works great, too.
• Garlic – Fresh minced garlic gives the best flavor, but if I’m short on time, I’ll use a teaspoon of jarred garlic or even garlic powder (about 3/4 teaspoon mixed in with the eggs). Leftover roasted garlic is amazing in this if you have some.
• Eggs –  I recommend using room temp eggs so they mix in more smoothly. If you want to lighten it up, you can swap in egg whites — use about 10 egg whites to replace the 5 whole eggs in this recipe.
• Heavy Cream – This makes the richest, creamiest keto quiche. You can sub in any keto-friendly milk if you prefer, like almond milk, coconut milk, or hemp milk.
• Cheese – I used shredded cheddar, but pretty much any cheese will work here. You can go shredded or crumbled depending on the type. Use whatever you love — here’s a full keto cheese list if you need ideas!
• Sea Salt & Black Pepper

My Basic Keto Quiche Formula!

I filled my quiche with broccoli and cheddar this time, but you can totally make it your own. That’s the best part — it’s super customizable. Here’s the simple formula I use so you can mix and match with whatever you have:

• 5 large eggs
• 1/3 cup heavy cream (or any keto-friendly milk)
• 1 to 1 ½ cups cooked veggies (like sautéed broccoli, spinach, mushrooms, etc.)
• 1 cup shredded cheese
• ½ to 1 tsp salt + seasonings to taste
• Optional: ½ to 1 cup cooked meat (bacon, sausage, ham, etc.)

How To Make A Keto Quiche

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.

1. Bake the crust. Bake the almond flour pie crust according to the instructions here, skipping the sweetener and adding extra salt. Let it cool before filling — and keep the oven on!
2. Cook the veggies. Sauté the broccoli and garlic until tender, then let them cool so they don’t cook the eggs when you mix it all together.

3. Mix the filling. In a big bowl, whisk together the eggs, cream, salt, and pepper. Stir in the cheese until it’s all combined and looking creamy.
4. Assemble. Layer the broccoli into the crust, pour the egg mixture over it, and spread everything out evenly.

5. Cook. Bake your keto quiche until the center is set and the top looks golden. Let it rest for a bit before slicing — it sets up better and slices more cleanly that way.

Serving Ideas

Not sure what to serve with your broccoli cheddar quiche? Here are some of my favorite sides and add-ons to turn it into a complete meal:

• Salads – I love serving keto quiche with something fresh on the side, like cucumber radish salad or strawberry spinach salad if I’m in the mood for sweet and savory.
• Baked Goods – Want to round it out? Try almond flour blueberry muffins, keto bagels, or a slice of keto coffee cake. And if you’re craving something sweet but easy, my chaffle recipe is always a hit.
• Sides – You can’t go wrong with a few brunch staples — I usually do oven bacon, a cup of keto coffee, or even some fresh fruit (just check my keto fruit list to keep it low carb).
