Crustless Keto Quiche - Easy, Flavorful, and Low-Carb

Prep Time10 minutes mins

Cook Time45 minutes mins

Total Time55 minutes mins

Servings: 8 servings

Ingredients

• 8 large eggs
• 1 cup heavy cream (or half cream, half unsweetened almond milk for a lighter texture)
• 1 1/2 cups shredded cheese (Cheddar, Gruyère, Swiss, or a mix)
• 1 cup cooked meat (bacon, sausage, ham, or rotisserie chicken), chopped
• 1 cup low-carb vegetables (spinach, mushrooms, broccoli, bell peppers), cooked and well-drained
• 2 tablespoons grated Parmesan (adds savory depth)
• 2 tablespoons chopped fresh herbs (chives, parsley, or basil), optional
• 2 cloves garlic, minced, optional
• 1/2 teaspoon onion powder
• 1/2 teaspoon kosher salt (adjust to taste, especially if your meat is salty)
• 1/4 teaspoon black pepper
• Pinch of nutmeg (classic with creamy egg dishes)
• 1 tablespoon butter or olive oil for greasing the dish

Instructions

• Heat the oven: Preheat to 350°F (175°C). Grease a 9-inch pie dish or a 9x9-inch baking dish with butter or olive oil.
• Prep fillings: If using raw veggies like mushrooms or peppers, sauté them until soft and any moisture cooks off. Drain well. Chop cooked meats into bite-size pieces.
• Whisk the custard: In a large bowl, whisk eggs until smooth. Add heavy cream, Parmesan, onion powder, salt, pepper, and nutmeg. Whisk until fully combined.
• Add flavor boosts: Stir in garlic and fresh herbs if using. Fold in shredded cheese, cooked meat, and vegetables.
• Assemble: Pour the mixture into the greased dish. Smooth the top and tap the dish gently to release air bubbles.
• Bake: Place on the middle rack and bake 30–40 minutes, until the center is just set and the edges are lightly golden. A knife inserted near the center should come out mostly clean.
• Rest and slice: Let the quiche rest 10 minutes before slicing. This helps it firm up and makes cleaner slices.
• Serve: Enjoy warm or at room temperature. Add a simple green salad or sliced avocado on the side if you like.

What Makes This Recipe So Good

• Low-carb without the work: No crust means fewer steps and fewer carbs. You get a high-protein, high-fat, low-carb meal with minimal effort.
• Fluffy, custardy texture: The blend of eggs, cream, and cheese makes a tender, rich filling that sets perfectly.
• Meal-prep friendly: It reheats well and tastes great hot or cold, making it ideal for make-ahead breakfasts or lunches.
• Customizable: Swap in your favorite meats, cheeses, and veggies.

  It’s a flexible formula you can tailor to your tastes.

• Great for using leftovers: A few slices of cooked bacon, a handful of spinach, or last night’s roasted veggies can all go in.

Storage Instructions

• Refrigerate: Cool completely, then store slices in an airtight container for up to 4 days.
• Freeze: Wrap individual slices tightly and freeze for up to 2 months. Thaw overnight in the fridge.
• Reheat: Warm in a 300°F (150°C) oven for 10–12 minutes, or microwave in short bursts to avoid rubbery eggs.

Why This is Good for You

• Low in carbs, high in satisfaction: Without a crust, you cut most of the carbs while keeping the protein and fat that keep you full.
• Protein-packed: Eggs and cheese supply complete protein to support muscle and steady energy.
• Healthy fats: Cream, cheese, and eggs provide fats that help with satiety on a keto or low-carb plan.
• Micronutrients: Add spinach, broccoli, or mushrooms for fiber, vitamins, and minerals that round out the meal.

Pitfalls to Watch Out For

• Watery quiche: Wet veggies release moisture and make a soggy slice.

  Sauté and drain them well before adding.

• Rubbery texture: Overbaking turns eggs tough. Pull it out when the center is just set and still has a slight jiggle.
• Too salty: Bacon, ham, and cheese can be salty. Taste your mix-ins and reduce added salt if needed.
• Stick to the pan: Grease the dish well, especially along the sides and rim where eggs can cling.
• Uneven baking: Overloading the dish can slow cooking.

  Keep fillings to about 2 cups total for best results.

Variations You Can Try

• Classic Lorraine-ish: Bacon, Gruyère, and a pinch of nutmeg.
• Greek style: Spinach, feta, olives, and a little oregano.
• Mushroom and Swiss: Sautéed mushrooms, Swiss cheese, and thyme.
• Broccoli Cheddar: Small broccoli florets (pre-steamed) and sharp Cheddar.
• Southwest: Chorizo, pepper jack, green chiles, and cilantro. Add a dollop of sour cream to serve.
• Dairy-light: Use 3/4 cup heavy cream plus 1/4 cup unsweetened almond milk and choose a milder cheese.
• No-meat veggie: Double the veggies (well-drained) and add extra herbs for flavor.

FAQ

Can I make this dairy-free?

Yes. Use full-fat coconut milk instead of cream and choose a dairy-free cheese that melts well.

The flavor will be slightly different, but the texture stays creamy.

What size pan works best?

A 9-inch pie dish or 9×9-inch baking dish works well. If you use a deeper dish, add 5–10 minutes to the bake time and check for doneness in the center.

How do I know when it’s done?

Look for set edges and a center that jiggles slightly but isn’t watery. A knife inserted near the center should come out mostly clean.

It will firm up more as it rests.

Can I use milk instead of cream?

You can, but the texture will be less rich and may release more moisture. For a lighter option, try half cream and half unsweetened almond milk.

Is this recipe good for keto macros?

Generally yes. Without the crust, most carbs come from veggies and dairy.

Exact macros depend on your ingredients, but each slice is usually low in net carbs and high in fat and protein.

Can I make mini quiches or muffins?

Absolutely. Grease a muffin tin well and fill each cup about three-quarters full. Bake 15–20 minutes, checking early to avoid overcooking.

Why did my quiche sink?

All egg bakes settle a bit as they cool.

If it sinks a lot, the custard may have been underbaked or had too much moisture. Cook veggies well and bake until just set.

Can I prepare it the night before?

Yes. Mix the custard and fillings, pour into the greased dish, cover, and refrigerate overnight.

Bake in the morning, adding a few extra minutes if the dish is very cold.

What cheeses melt best?

Cheddar, Gruyère, Swiss, Monterey Jack, and mozzarella melt smoothly. A small amount of Parmesan adds umami without affecting the melt.

How can I add more flavor?

Use a mix of cheeses, fresh herbs, and aromatics like garlic or shallots. A pinch of smoked paprika or a splash of hot sauce in the custard also boosts flavor.
