If homemade, make your pie crust at least 2 hours in advance and chill.
Heat oven to 375°F (191°C).
Grease two 24-count mini muffin pans.
Shape the Mini Crusts
Place 1 chilled pie crust on a lightly floured surface.
Roll into a 12-inch circle, about ⅛ inch thick.
Cut circles with a 2½-inch round cutter. Gather scraps, re-roll once, and cut again if needed.
You should get about 24 rounds per crust.
Press each round into the muffin wells, smoothing the bottom and pressing dough up the sides.
Make the Egg Filling
In a large bowl, whisk together eggs, milk, cream, salt, pepper, nutmeg, and garlic powder until smooth.
Divide the muffin cups into 3 groups of 16 for each flavor combo.
Sprinkle each cup with the appropriate add-ins (about 1 teaspoon filling + a sprinkle of cheese).
Lorraine: bacon + Gruyère
Spinach + feta
Mushroom + Swiss
Pour the egg filling over the top, filling each crust about ¾ full.
Bake for 25–28 minutes, until centers are just set and crust edges are lightly golden.
Cool for 5 minutes in the pan, then gently remove. Serve warm or at room temperature.
Notes
Erren’s Top Tips
Use well-greased pans or nonstick pans to avoid sticking, especially with cheese-heavy fillings.Don’t skip pre-cooking vegetables. Any moisture left in mushrooms or spinach will make the quiches watery.Fill only to three-quarters full. Overfilling causes them to puff too high and collapse.Let them rest before removing. This helps the custard finish setting and keeps them intact.
Variations & Add-Ins
Ham & Cheddar: Swap bacon for diced ham and use sharp cheddar for a classic combo.Roasted Veggie: Use roasted zucchini, peppers, and onions for a vegetarian option with deeper flavor.Sausage & Pepper: Brown sausage with diced peppers for a hearty version.Goat Cheese & Herbs: Add fresh herbs and creamy goat cheese for a lighter, tangy variation.
Storage & Freezing
Store cooled quiches in an airtight container in the fridge for up to 3 days.Reheat in a 300°F oven until warmed through to keep the texture soft.
