Easy Chicken Quiche

Step 1
Preheat oven to 375 degrees F (190 degrees C). Grease a 9-inch pie dish with cooking spray.

Step 2
Line the prepared pie dish with puff pastry, covering base and sides. Trim excess pastry. Brush bottom with Dijon mustard.

Step 3
Melt butter in a saucepan over medium heat. Add chopped green onions and cook until tender, about 5 minutes. Add garlic and cook for 1 minute more. Mix in chicken, and cook for 1 minute more.

Step 4
Whisk eggs, heavy cream, salt, nutmeg, ground black pepper, and Italian seasoning together in a bowl.

Step 5
Layer 1/2 of the Gouda cheese over the puff pastry and top with chicken mixture. Pour in egg mixture. Sprinkle the remaining Gouda cheese on top.

Step 6
Bake in the preheated oven until set and golden, about 25 minutes.
