Sausage Mushroom Quiche

Ingredients

• 1 ready-to-use pie crust
• 1/2 pound sausage
• 1 teaspoon vegetable oil, or as needed
• 1 onion, diced
• 6 eggs
• 1/2 cup milk
• 1/4 cup mayonnaise
• 2 cups shredded pepperjack cheese
• 1 cup diced mushrooms
• 1 teaspoon minced garlic
• 1/4 cup shredded sharp Cheddar cheese

Directions

Preheat oven to 400 degrees F (200 degrees C). Press pie crust into a 9-inch pie dish.

Heat a large skillet over medium-high heat. Cook and stir sausage in the hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease.

Heat oil in a skillet over medium heat; cook and stir onion in the hot oil until softened, 5 to 10 minutes.

Whisk eggs, milk, and mayonnaise together in a bowl until evenly mixed; stir sausage, onion, pepperjack cheese, mushrooms, and garlic into egg mixture. Pour mixture into the prepared pie crust; top with Cheddar cheese.

Bake in the preheated oven until a knife inserted into the center of the quiche comes out clean, about 45 minutes.
