Quiche is one of those dishes that feels special but doesn’t ask much of you in the kitchen. This keto version keeps all the rich, custardy goodness you love while cutting the carbs way down. It’s perfect for brunch, meal prep, or a quick dinner with a simple salad.
You can change the fillings based on what you have, and it always tastes like you put in more effort than you did. If you miss the cozy feel of a classic quiche while eating low-carb, this is your answer.
Ingredients
Method
- Preheat and prep. Heat the oven to 350°F (175°C). Grease a 9-inch pie dish or tart pan.
- Make the crust. In a bowl, mix almond flour, Parmesan, salt, and garlic powder. Stir in melted butter and 1 egg until it forms a damp, crumbly dough.
- Press the crust. Press the dough evenly into the dish, pushing it up the sides. Use the base of a measuring cup to smooth and compact the crust.
- Par-bake. Bake the crust for 10–12 minutes until lightly golden. Set aside to cool slightly. This helps prevent a soggy bottom.
- Cook the fillings. In a skillet over medium heat, cook bacon until crisp. Remove and crumble. Pour off most of the fat, leaving about a teaspoon. Sauté green onions and spinach until wilted and dry. Cool slightly.
- Whisk the custard. In a large bowl, whisk eggs, heavy cream, salt, pepper, and a pinch of nutmeg until smooth. Don’t overbeat—just combine.
- Assemble. Spread the spinach and onions over the crust. Add bacon and most of the cheese. Pour the custard evenly over the top, then sprinkle on the remaining cheese.
- Bake. Bake for 28–35 minutes, until the center is just set and the top is lightly golden. The middle should jiggle slightly but not look watery.
- Rest and slice. Let the quiche sit for 10–15 minutes before slicing. This helps it set and makes cleaner slices.
- Garnish and serve. Top with chopped chives or parsley. Serve warm or at room temperature.

- Freezer: Wrap individual slices in plastic wrap, then foil, or place in freezer-safe containers.
Freeze for up to 2 months.

Benefits of This Recipe
- Low-carb and keto-friendly: Almond flour crust and high-fat filling keep carbs low and satiety high.
- Flexible: Swap in different meats, cheeses, or veggies without changing the method.
- Meal prep hero: One bake gives multiple meals that store and reheat well.
- Balanced macros: A good mix of protein and fat helps you stay full and energized.
- Family-friendly: Tastes like classic quiche, so everyone can enjoy it—even those not eating low-carb.
Common Mistakes to Avoid
- Skipping the par-bake: Without it, the crust can turn soggy. A short bake keeps it crisp.
- Wet veggies: Spinach, mushrooms, and zucchini hold water.
Sauté and drain them so the custard sets properly.
- Overbaking: This leads to a dry, rubbery texture. Pull it when the center still has a slight jiggle.
- Too much salt: Bacon and cheese are salty. Season the custard lightly and taste the cooked fillings before adding more.
- Overfilling: Leave a little space at the top of the crust.
The custard puffs slightly as it bakes.
Alternatives
- Crustless quiche: Skip the crust and grease the dish well. Bake the filling and custard directly in the pan for fewer calories and even fewer carbs.
- Coconut flour crust: Use 3/4 cup coconut flour, 4 eggs, 1/3 cup melted butter, and seasonings. The texture is firmer and slightly sweet.
- Dairy-free: Replace heavy cream with full-fat coconut milk and use a dairy-free cheese or skip cheese.
Choose meats and add-ins without dairy.
- Meatless: Load up on sautéed spinach, mushrooms, bell peppers, and onions. Add extra cheese for richness.
- Different meats: Try cooked sausage, diced ham, or shredded rotisserie chicken.
- Cheese swaps: Gruyère is classic, but cheddar, pepper jack, or feta change the vibe nicely.
FAQ
How many carbs are in a slice?
Exact numbers vary with fillings, but a typical slice with almond flour crust, spinach, bacon, and cheese lands around 3–5 net carbs. Crustless versions are usually a bit lower.
Can I use milk instead of heavy cream?
Heavy cream makes the custard rich and helps it set with fewer carbs.
If you use milk or half-and-half, the texture will be lighter and the carb count higher. If you must swap, use the fattest option you can and reduce the amount slightly.
Why is my quiche watery?
Usually it’s excess moisture from vegetables or underbaking. Sauté and drain veggies well, par-bake the crust, and bake until the center is just set with a slight jiggle.
Can I bake this in a muffin pan?
Yes.
Grease the cups well and press a thin layer of crust into each, or go crustless. Bake 12–18 minutes depending on size, watching for doneness. Great for grab-and-go breakfasts.
Do I need to blind-bake with pie weights?
No.
The almond flour crust holds up without weights. A short par-bake is enough to firm it before adding the filling.
What pan works best?
A 9-inch pie dish or tart pan with a removable bottom works well. Ceramic or metal both work; metal may brown the crust a bit faster.
Can I make it ahead?
Yes.
Bake the quiche, cool, and refrigerate. Reheat gently in the oven. You can also prep the crust and fillings a day ahead and bake fresh the next day.
In Conclusion
A keto quiche is a dependable, go-to recipe that feels indulgent without breaking your carb goals.
The almond flour crust is easy, the custard is silky, and the fillings are flexible. Make it for brunch, pack it for lunch, or serve it for dinner with a crisp salad. Once you try it, you’ll keep it in your rotation. It’s simple, satisfying, and built to fit your life.
