Ingredients

• 1 piece pre-made pie crust
• 8 ounces mild or spicy ground sausage
• 6 ounces portabella mushrooms
• 1 medium yellow onion
• 1 tablespoon olive oil
• 5 large eggs
• 1 cup heavy cream
• 0.5 cup whole milk
• 1 cup shredded Gruyere cheese
• 0.5 teaspoon garlic powder
• 0.5 teaspoon dried thyme
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Place the pre-made pie crust into a 9-inch pie dish and crimp the edges. Set aside.

Step 2

In a medium skillet over medium heat, cook the ground sausage until browned and cooked through, about 6-8 minutes. Drain any excess grease and transfer the sausage to a plate lined with paper towels.

Step 3

Thinly slice the yellow onion and chop the portabella mushrooms into small pieces.

Step 4

In the same skillet, heat 1 tablespoon of olive oil over medium heat. Add the onions and cook, stirring occasionally, until they soften and start to caramelize, about 8 minutes.

Step 5

Add the portabella mushrooms to the skillet with the onions. Cook for an additional 5-7 minutes, or until the mushrooms release their moisture and become tender. Remove from heat.

Step 6

In a large mixing bowl, whisk together the eggs, heavy cream, and whole milk until smooth. Stir in the garlic powder, dried thyme, salt, and black pepper.

Step 7

Sprinkle the shredded Gruyere cheese evenly over the bottom of the pie crust. Then layer the cooked sausage, caramelized onions, and mushrooms over the cheese.

Step 8

Carefully pour the egg mixture over the sausage and vegetables, ensuring everything is covered and evenly distributed.

Step 9

Bake the quiche in the preheated oven for 35-40 minutes, or until the egg custard is set and the top is lightly golden brown.

Step 10

Allow the quiche to cool for 5-10 minutes before slicing. Serve warm or at room temperature.
