Start by setting your oven to 375°F (190°C) to preheat. Spray your mini muffin pan or muffin tin with non-stick cooking spray to ensure easy removal after baking.
Prepare the Pie Crusts: Roll out the pie crusts and use a cookie cutter or a small measuring cup to cut circles from the dough. You’ll want the circles to be slightly larger than the mini muffin cups. Press each circle of dough gently into the muffin cups, lining the bottom and up the sides to form your mini quiche crusts.
Whisk the Egg Mixture: In a large bowl, whisk together the eggs, heavy cream, and a pinch of salt and pepper. This mixture will create the creamy filling for your mini quiches. You can also use a measuring cup for more precise amounts. If you prefer a lighter filling, feel free to substitute the heavy cream with milk or whole milk for a slightly different texture.
Add Fillings: Now it’s time to get creative! Spoon your desired fillings into each mini muffin cup. You can include a combination of crumbled bacon, shredded cheese (Swiss cheese, cheddar, or gruyere are great options), chopped spinach, and bell peppers. Feel free to experiment with different quiche add-ins based on your preferences.
Pour the Egg Mixture: Carefully pour the egg mixture over the fillings, filling each mini muffin cup about 3/4 full. Be sure not to overflow the crusts. If you’re making a crustless mini quiche, simply pour the egg mixture directly into the pan without any crust.
Bake: Place your mini quiches in the oven and bake for 20-25 minutes, or until the quiches are puffed up and golden brown on top. The bake time will depend on the size of your muffin tin and the thickness of the egg filling. Keep an eye on them during the last few minutes to ensure the crust is golden brown and the egg mixture is set.
Cool and Serve: Once the mini quiches are done baking, let them cool for about 5 minutes before removing them from the pan. If you used a mini muffin pan, they should pop out easily. Serve warm, and enjoy the crispy, creamy goodness!
