Ingredients
Method
- Prep the Crust
- Preheat oven to 375°F (190°C). Spray a 12-cup standard muffin tin generously with non-stick spray.
- Let refrigerated pie crust sit at room temperature 15–20 minutes until pliable.
- On a lightly floured surface, unroll the dough. Use a round cookie cutter slightly larger than the muffin cup opening (about 3½–4 inches) to cut out circles.
- Press each dough circle into a muffin cup, gently pressing it into the base and up the sides. Keep the dough cold — colder dough makes a flakier crust.
- Blind Bake the Crust (Optional but Recommended)
- Line each dough cup with a small piece of parchment; fill with pie weights or dry beans.
- Bake 15 minutes until edges are lightly set. Remove parchment and weights.
- Bake 5–8 more minutes until the bottoms are dry and just barely golden. Remove and let cool slightly.
- Prepare the Fillings
- Bacon: Fry bacon until crisp; drain on paper towels and crumble. Sauté diced onion in the same pan until soft.
- Spinach: Heat a drizzle of olive oil over medium heat; add garlic and spinach; sauté 1–2 minutes until fully wilted. Squeeze out all excess moisture in a paper towel before using.
- Mushrooms: Melt butter in a pan over medium-high heat; add mushrooms; cook undisturbed until deeply golden, about 4–5 minutes. Add garlic and thyme; cook 1 minute more.
- Make the Egg Custard
- In a medium bowl or 4-cup measuring cup, whisk eggs, milk, heavy cream, salt, pepper, and nutmeg until smooth and slightly frothy — about 1 minute of vigorous whisking. The measuring cup spout makes pouring into cups much neater.
- Assemble and Bake
- Distribute your chosen fillings evenly into the pastry shells — cheese and fillings go in first.
- Pour the egg custard slowly over the fillings, filling each cup about ¾ full. Leave space for the custard to puff up during baking.
- Bake 25–30 minutes until the tops are puffed, golden brown, and the centers are just set. A toothpick inserted in the center should come out clean.
- Let cool in the muffin tin 5 minutes before removing. Run a thin spatula around the edges and lift out carefully.
- Crustless Mini Quiche (Egg Muffin Style)
- Skip the pastry completely. Spray the muffin tin very generously. Add fillings directly to the greased cups, pour egg custard over top, filling ¾ full. Bake at 375°F for 20–25 minutes until set and golden on top. Cool 5 minutes before removing — these are more delicate, so give them time to firm up.
Notes
Cold dough = flaky crust: Work quickly and keep dough chilled; the heat shock in the oven creates steam from the cold butter for flaky layers.
Don't overfill: Leave ¼ inch of space at the top — the custard puffs as it bakes.
Add fillings first, then pour custard over: This ensures every quiche has an even distribution of filling in every bite.
Frozen spinach: Thaw completely and squeeze every drop of water out — excess moisture makes the custard watery and prevents setting.
Cheese tip: Grate cheese from a block for the best melt; pre-shredded cheese contains anti-caking agents that can affect the texture.
Dairy-free option: Replace milk and cream with unsweetened plant-based milk (oat, soy, or full-fat coconut milk for richness).
Serving ideas: Serve warm with a simple green salad, fresh fruit salad, or yogurt parfaits for a complete brunch spread. Garnish with fresh chives, parsley, or thyme just before serving.
