Ingredients
To create this delectable Crustless Mushroom Quiche, gather the following ingredients:
- 2 Tbsp. unsalted butter: This golden butter will serve as the aromatic base for sautéing.
- 8 oz. white button mushrooms, sliced: These juicy mushrooms add earthiness and depth to the dish.
- 3 shallots, finely chopped: Their sweet and mild flavor balances perfectly with the richness of the cheese.
- 1 1/2 cups Gruyere cheese, shredded: Creamy and nutty, Gruyere melts beautifully to give the quiche an indulgent finish.
- 1 cup heavy cream: This adds luxurious creaminess, making the quiche rich and satisfying.
- 1/2 cup whole milk: A touch of dairy that lightens the texture without compromising flavor.
- 4 large eggs, lightly beaten: Essential for binding the ingredients together, creating a fluffy interior.
- 1 Tbsp. Dijon mustard: A punch of tanginess that elevates the flavor profile.
- 1 1/2 Tbsp. fresh chives, chopped: These vibrant green herbs add freshness and a hint of onion flavor.
- 1/2 tsp. kosher salt: Enhances all the flavors in the dish.
- 1/2 tsp. black pepper: Adds a subtle kick of heat to round out the taste.
- 2 Tbsp. grated Parmesan cheese, divided: Its sharp, salty character complements the quiche perfectly and creates a delightful crust.
Step-by-Step Directions
To prepare your Crustless Mushroom Quiche, follow these simple instructions:
-
Preheat your oven: Heat it to 350°F (175°C). Prepare a deep-dish pie plate or an oval baking dish by spraying it with nonstick cooking spray and setting it aside for later.
-
Sauté the mushrooms and shallots: In a large skillet, heat the unsalted butter over medium-high heat until melted. Add in the sliced mushrooms and finely chopped shallots. Sauté them until they become beautifully browned and fragrant.
-
Layer the cheese and mushroom mixture: Sprinkle the shredded Gruyere cheese and sautéed mushrooms evenly across the bottom of your prepared dish, allowing the flavors to meld together.
-
Mix the filling: In a medium bowl, whisk together the heavy cream, whole milk, lightly beaten eggs, Dijon mustard, fresh chives, kosher salt, black pepper, and one tablespoon of the grated Parmesan cheese until well combined.
-
Combine and bake: Pour this luscious mixture over the cheese and mushrooms in the dish. Finish by sprinkling the remaining tablespoon of Parmesan cheese on top. Bake the quiche in the preheated oven for about 30-35 minutes until the top is light golden brown and the center has set.
-
Cool and serve: Once done, remove the quiche from the oven and allow it to cool for 5-10 minutes. This makes it easier to slice; scoop out portions onto plates and serve warm.

To elevate your Crustless Mushroom Quiche, consider these chef’s secrets:
