Bite-sized mini quiches with flaky pastry and savory fillings are a high protein, elegant family party appetizer. These versatile little bites are perfect for brunch entertaining.
Preheat oven to 375°F and lightly grease a mini muffin pan.
Roll out the pie crust sheet and cut into circles using a 2.5-inch cutter. Gently press each circle into the muffin cavities, making sure the pastry edges are snug.
In a bowl, whisk eggs with milk, salt, pepper, and garlic powder until smooth and well combined.
Fill each pastry shell with chopped spinach, diced ham, and shredded cheddar cheese, dividing ingredients evenly across all mini quiches.
Carefully pour the egg mixture into each cavity, filling nearly to the top, and bake for 20-22 minutes, or until the quiches are puffed and the centers are just set with golden edges. Cool 5 minutes before serving.
