Key element — cook the mushrooms first
Raw mushrooms weep into the eggs and the center stays wet. Sear them until the pan is dry, then they sit on top the way the dish does.
Ingredients
Quiche (6 slices)
- 6 large eggs
- ½ cup heavy cream
- 4 slices bacon, cooked and chopped
- 8 oz mushrooms, sliced
- 1 cup shredded cheese
- 2 garlic cloves, minced
- 1 Tbsp butter or bacon fat
- ½ tsp salt
- ¼ tsp black pepper
- Chopped parsley, to finish
Swaps
- Ham: Use 4 oz diced ham instead of bacon.
- Spinach: A handful of squeezed spinach with the mushrooms.
- No cream: Use unsweetened almond milk. The set is a little less rich.
- Crust: An almond-flour crust adds carbs. This card is crustless.
Instructions
| 1 | Heat the oven. Heat to 350°F (175°C). Grease a 9-inch fluted dish. |
| 2 | Cook the fillings. Sear the mushrooms in butter until the pan is dry. Add garlic for 30 seconds. Stir in the chopped bacon. |
| 3 | Mix. Whisk eggs, cream, salt, and pepper. Stir in half the cheese. Pour into the dish. Scatter the mushroom-bacon mix and the rest of the cheese on top. |
| 4 | Bake. Bake 35–40 minutes until the center is just set and the top is golden. Rest 10 minutes. Finish with parsley and cut 6 slices. |
Pro tips
- A wet center means it needs 5 more minutes, not a higher oven.
- Resting is what lets you cut clean slices.
- Save a few mushroom slices for the top so they show, like the photo.
- A pastry crust is not in these numbers.
- Macros are per slice, 6 from this dish.
