This crustless keto ham and cheese quiche turns simple breakfast staples into a rich, savory custard loaded with diced ham and two kinds of cheese. With no flour crust, it stays low in carbs while delivering plenty of protein, and it reheats beautifully for make-ahead mornings.
Ingredients
- 8 large eggs
- 1 cup heavy cream
- 8 oz cooked ham, diced (look for no-sugar-added ham)
- 1 1/2 cups shredded sharp cheddar cheese (about 6 oz)
- 1/2 cup shredded Gruyère or Swiss cheese (about 2 oz)
- 3 green onions, thinly sliced (white and green parts)
- 1 tablespoon unsalted butter, for greasing the dish
- 1/2 teaspoon fine sea salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- Pinch of ground nutmeg (optional, classic quiche flavor)
Instructions
- 1
Preheat the oven to 375°F (190°C). Grease a 9-inch pie dish or quiche pan generously with the butter so the crustless quiche releases cleanly.
- 2
In a large bowl, whisk the eggs until smooth, then whisk in the heavy cream, salt, pepper, garlic powder, and nutmeg until fully combined.
- 3
Stir in the diced ham, sliced green onions, the shredded cheddar, and half of the Gruyère, reserving the rest of the Gruyère for the top.
- 4
Pour the mixture into the prepared dish, spread the fillings evenly, and sprinkle the reserved Gruyère over the surface.
- 5
Bake for 35-40 minutes, until the center is just set with a slight jiggle and the top is golden. If it browns too fast, tent loosely with foil for the last 10 minutes.
- 6
Let the quiche rest for 10 minutes so the custard firms up, then slice into 6 wedges and serve warm.
Tips & notes
- Use a well-cured, no-sugar-added ham to keep carbs low; honey-glazed or maple hams add hidden sugars that push net carbs higher.
- Swap in cooked bacon or breakfast sausage for the ham, or fold in a handful of sautéed spinach or mushrooms (pat them dry first to avoid a watery custard).
- Store leftovers covered in the fridge for up to 4 days, or freeze individual slices for up to 2 months. Reheat in a 325°F oven or microwave until warmed through.

Frequently asked questions
- How many carbs are in keto ham and cheese quiche?
- Each slice has 3.2g net carbs (3.6g total carbs minus 0.4g fiber), 348 calories, 22g protein, and 26g fat. This recipe makes 6 slices. Going crustless keeps the carbs low, with most coming from the cream, cheese, and green onions.
- Why is this quiche crustless?
- Traditional quiche crust is made with wheat flour, which is too high in carbs for keto. Skipping the crust keeps each slice at just 3.2g net carbs while the egg-and-cream custard still bakes into firm, sliceable wedges that hold together perfectly.
- Can I make keto quiche ahead of time?
- Yes. This quiche is ideal for meal prep. Bake it fully, cool, then refrigerate for up to 4 days or freeze for up to 2 months. Reheat single slices in the microwave or a 325°F oven, making it a fast, protein-packed keto breakfast on busy mornings.
