Italian Sausage and Arugula Quiche

Total Time1 hour
Servings: 6

Ingredients

  • 1 frozen 9” pie shell, unbaked (I use The Maine Pie Co. Gluten-Free)
  • ½ pound bulk hot Italian sausage (sub mild)
  • 2 cups roughly chopped baby arugula
  • ¼ cup roughly chopped piquillo peppers
  • ½ teaspoon crushed red pepper flakes
  • 6 large eggs
  • ¾ cup whole milk
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • 1 cup aged Manchego cheese, divided
  • 2 tablespoons finely chopped chives, for serving

Instructions

  • Preheat the oven to 375°F and place the frozen pie crust shell on a sheet pan or in a pie dish.
  • Heat a large skillet over medium-high heat. Add the Italian sausage and cook, breaking up the meat with the edge of a spoon, until cooked through and no longer pink, about 5 minutes. Reduce the heat to low, add and arugula, piquillo peppers, and red pepper flakes. Toss until the arugula just wilts, about 2 minutes.
  • Drain off excess fat and transfer the Italian sausage mixture to the center of the pie crust shell and spread into an even layer. Set aside.
  • In a medium bowl, whisk together the eggs, milk, salt, and pepper until well combined and frothy.
  • Sprinkle ¾ cup of the Manchego cheese over the sausage mixture in the pie crust. Then, pour the egg mixture on top. Finish with the remaining 1/4 cup Manchego cheese.
  • Carefully transfer to the preheated oven and bake until the center is completely set, 35 to 40 minutes.
  • Remove from the oven and let cool for 5 to 10 minutes.
  • Finish with freshly chopped chives. Slice, serve and enjoy!

Notes

Storing Quiche:
Once your quiche has cooled down after baking, store it in an airtight container or wrap it tightly in plastic wrap. Place it in the refrigerator promptly, and it should stay fresh for up to 3-4 days.
Reheating the Quiche:
Microwave: For a quick reheat, microwave individual slices on a microwave-safe plate for about 1-2 minutes, or until heated through.
Oven: To reheat the entire quiche or larger portions, preheat your oven to around 350°F. Cover the quiche with foil to prevent over-browning, then place it in the oven for about 15-20 minutes, or until heated through.
Air Fryer: If you have an air fryer, you can reheat quiche slices in it for a crispier texture. Preheat the air fryer to 325°F (160°C) and heat the quiche for about 5-8 minutes, depending on thickness and desired crispness.
