Quiche feels fancy, but it’s secretly one of the easiest dishes you can make. This keto version keeps all the creamy, cheesy goodness without the carb-heavy crust. It’s great for weekend brunch, meal prep, or a quick dinner with a simple side salad.
You can customize it with your favorite meats and veggies, and it reheats like a dream. If you’ve been missing quiche on a low-carb diet, this recipe brings it back to the table.
Ingredients
Method
-
Preheat and prep: Heat your oven to 350°F (175°C).
Grease a 9-inch pie dish with butter or oil.
-
Make the crust (optional): In a bowl, mix almond flour, Parmesan, garlic powder, onion powder, and salt. Stir in melted butter and the egg until a soft dough forms. Press evenly into the pie dish, pushing up the sides.
Prick the bottom with a fork. Bake for 10 minutes to set. Remove and cool while you prepare the filling.
-
Cook your add-ins: Sauté vegetables in a little oil with a pinch of salt until they release moisture and soften.
Drain off excess liquid. Cook bacon or sausage until crisp and crumble. Let everything cool slightly.
-
Whisk the custard: In a large bowl, whisk eggs, heavy cream, salt, pepper, paprika, and nutmeg until smooth.
Stir in half the cheese.
-
Assemble: Scatter cooked meats and vegetables evenly over the crust (or directly into the greased dish if crustless). Sprinkle with remaining cheese. Pour the egg mixture over the top.
Tap the dish gently to settle.
-
Bake: Bake for 30–40 minutes, until the center is just set and the top is lightly golden. A knife inserted near the center should come out mostly clean with a slight wobble.
-
Rest and serve: Let the quiche rest for 10–15 minutes before slicing. Garnish with fresh herbs if you like.
Why This Recipe Works
This keto quiche skips traditional pie crust and uses an almond flour crust or a crustless method for fewer carbs and faster prep. The filling is a simple mix of eggs, cream, cheese, and flavorful add-ins that set up beautifully.
Using heavy cream keeps the texture rich and custardy, not rubbery. A quick pre-bake of the crust (or a hot buttered dish for crustless) helps the quiche release cleanly and prevents sogginess. The result is a golden, savory bake that slices neatly and tastes great hot or cold.

- 1 1/2 cups almond flour
- 1/4 cup grated Parmesan

- 2 tablespoons finely chopped onion or green onion
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon smoked paprika or paprika (optional)
- Pinch of nutmeg (especially good with spinach or Swiss)
- 1 tablespoon chopped fresh herbs (parsley, chives, or thyme), optional
- Butter or avocado oil for greasing
- Equipment:
- 9-inch pie dish or tart pan

Keeping It Fresh
Quiche stores well and tastes even better the next day.
Let it cool completely, then cover and refrigerate for up to 4 days. Reheat slices in a 300°F (150°C) oven for 10–12 minutes or microwave on low power in short bursts to avoid overcooking. For longer storage, wrap slices tightly and freeze for up to 2 months.
Thaw in the fridge overnight and reheat as above for best texture.
Benefits of This Recipe
- Low-carb and keto-friendly: Almond flour crust or crustless keeps net carbs low without sacrificing flavor.
- High in protein and fat: A satisfying meal that keeps you full and steady between meals.
- Customizable: Swap cheeses, meats, and vegetables based on what you have.
- Meal-prep friendly: Makes 6–8 slices that reheat well all week.
- Great for any meal: Works for breakfast, brunch, lunch, or dinner with a simple side.
Common Mistakes to Avoid
- Using watery veggies raw: Always sauté and drain vegetables to prevent a soggy quiche.
- Overbaking: Pull the quiche when the center still has a slight jiggle. It finishes setting as it cools.
- Skipping salt: Eggs and cream need proper seasoning or the quiche will taste flat.
- Too much filling volume: Overloading with veggies or meat can keep the custard from setting. Keep total add-ins around 1 1/2–2 cups.
- Thin crust edges: If using a crust, press it evenly up the sides so it doesn’t slump or burn.
Recipe Variations
- Crustless Keto Quiche: Skip the almond flour crust.
Generously butter the dish and proceed. Carbs drop even more, and it bakes slightly faster.
- Spinach and Feta: Use sautéed spinach (squeezed dry), crumbled feta, and a pinch of nutmeg. Add a touch of lemon zest for brightness.
- Bacon and Cheddar: Classic, hearty, and always a hit.
Add green onions for a fresh bite.
- Mushroom and Gruyère: Sauté mushrooms until browned and dry. Add thyme and Gruyère for a bistro-style vibe.
- Broccoli and Swiss: Steam or sauté small broccoli florets until just tender. Pair with Swiss or Jarlsberg and a sprinkle of paprika.
- Dairy-Light Option: Swap heavy cream for a mix of unsweetened almond milk and full-fat sour cream (texture will be slightly less rich).
- Spicy Sausage: Use hot Italian sausage, pepper jack cheese, and a dash of chili flakes.
FAQ
Can I make this quiche without a crust?
Yes.
Grease the pie dish well with butter or oil, add your fillings, pour in the custard, and bake. It sets beautifully and slices cleanly.
What’s the best cheese for keto quiche?
Cheddar, Gruyère, Swiss, and Monterey Jack all melt well and add great flavor. Mixing sharp cheddar with a milder cheese gives balance.
How do I keep the quiche from being watery?
Sauté vegetables to cook off moisture, drain any excess, and avoid overloading the custard.
Let the quiche rest after baking so the custard firms up.
Can I use coconut flour for the crust?
Coconut flour behaves differently and absorbs more liquid. It’s not a 1:1 swap. If you prefer coconut flour, use a crust recipe specifically developed for it.
How many carbs are in a slice?
It depends on your ingredients and whether you use a crust.
As a rough guide, a crustless version with bacon, cheese, and spinach can land around 3–4g net carbs per slice (1/8 of the pie). With an almond flour crust, expect about 5–6g net carbs per slice.
Can I make it ahead?
Absolutely. Bake it the day before, chill, and reheat gently.
Or assemble the filling and crust separately, refrigerate up to 12 hours, then bake fresh.
What size pan should I use?
A standard 9-inch pie dish works best. If using a deep dish, you may need a few extra minutes of baking. If using a tart pan, place it on a sheet tray for stability.
Why did my quiche crack?
Overbaking or rapid temperature changes can cause cracking.
Pull it when it’s just set, and let it cool gradually on the counter.
Can I make mini quiches?
Yes. Use a greased muffin tin and bake 14–18 minutes, watching for a just-set center. Great for portion control and freezing.
Is there a dairy-free version?
You can try full-fat coconut milk and a dairy-free cheese, but the texture and flavor will differ.
The classic custardy texture relies on dairy fat.
In Conclusion
Keto quiche is simple, versatile, and satisfying. With a few pantry staples and your favorite fillings, you get a rich, low-carb dish that fits any meal. Keep the technique straightforward—sauté veggies, season well, bake until just set—and it will turn out reliably every time.
Make it your own and enjoy the kind of comfort food that loves you back.
