If you’re looking for a low-carb brunch, this caramelized onion and gruyére quiche is for you. “It may easily be one of the best keto quiches I have ever made,” -Carolyn of All Day I Dream About Food.

By: All Day I Dream About Food


For the crust:

  • 1 1/2 cups almond flour
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon salt
  • 1/4 cup butter, melted

For the filling:

  • 1/4 cup butter
  • 1 onion, thinly sliced
  • 4 ounces Gruyére, grated
  • 6 Pete and Gerry’s Organic Eggs
  • 2/3 cup cream
  • 1 teaspoon salt
  • 1/2 teaspoon pepper


To make the crust:

Step 1

Preheat the oven to 325F. In a medium bowl, whisk together the almond flour, garlic powder, and salt. Stir in the melted butter until the dough resembles coarse crumbs.

Step 2

Turn the loose dough out into a 9-inch glass or ceramic pie pan. Press firmly into the bottom and up the sides. Use a flat-bottomed glass or measuring cup to even out the bottom of the crust.

Step 3

Crimp the edges and prick the bottom all over with a fork. Bake 10 to 12 minutes, until slightly puffed and just starting to brown. Remove and let cool while preparing the filling.

To make the filling:

Step 1

In a large skillet over medium-low heat, melt the butter. Add the onions and sprinkle with salt and pepper. Cook, stirring frequently, until the onions are soft and caramelized. Do not let them become crispy. This can take up to 20 minutes.

Step 2

Sprinkle the crust with the caramelized onions and half of the grated Gruyére cheese.

Step 3

In a large bowl, whisk together the eggs, heavy cream, salt, and pepper. Pour over the onions and cheese in the crust. Sprinkle the top with the remaining shredded cheese.

Step 4

Bake 35 to 40 minutes or until the filling is just set in the center. Remove and let cool for 15 minutes before serving.

This is exceptional! I would say that the crust isn't all that good after the first day but the filling is just delicious! I'm planning on making this again!

We're so thrilled that you enjoyed it, Lynn! It's true that almond flour crust does not hold up quite as well as regular crust, but it can still be delicious after soaking up a bit of that creamy egg mixture. If you decide to reheat leftovers, baking them for a very short time at a high temperature should help bring some crunch back into that crust. Glad to hear that this is one of those recipes you'll keep going back to!
