Swiss Cheese & Mushroom Quiche

Directions

Preheat oven to 375℉ (190℃).

Melt the butter in a small pan. Add onions, and sauté over medium heat for a few minutes.

When they begin to soften, add mushrooms, salt, pepper, thyme, and mustard.

Sauté about 5 minutes more and remove from heat.

Combine eggs, milk, and flour in a blender or food processor, and beat well.

Spread the grated cheese over the bottom of the unbaked crust and spread the onion-mushroom mixture on top.

Pour in the custard, and sprinkle top with paprika.

Bake for 35 to 45 minutes, or until solid in the center. Serve hot, warm, or at room temperature.
