Mini Quiches

Mini quiches are savory tarts baked in a muffin tin, with a buttery crust and a creamy egg filling studded with cheese and mix-ins. They bake fast, hold their shape, and taste good warm or at room temperature, making them ideal for breakfast, brunch, or make-ahead entertaining. The key is keeping the oven temperature moderate so the custard sets before the crust browns too dark.

Ingredients for Mini Quiches

Pie dough (or phyllo sheets) forms the shell and gets crispy as it bakes. Eggs and heavy cream make the custard rich and set it firm. Gruyere cheese and sharp cheddar add flavor without making the filling grainy. Bacon, spinach, mushrooms, or ham bring texture and taste. Salt, black pepper, and fresh thyme season the whole thing. Butter keeps the crust tender.

Why This Mini Quiches Works

A custard filling needs gentle, even heat so the eggs set without curdling or puffing up and falling. Baking at 375°F (190°C) gives the crust time to brown while the center stays creamy. If the oven runs hot, the edges brown before the middle firms up, and you end up with a sunken, watery quiche.

Pre-baking the shells for a few minutes seals them and stops them from getting soggy where they touch the filling. Grating cheese from a block, rather than using pre-shredded, prevents starch from making the custard grainy or causing it to break. Letting the quiches cool in the pan for a few minutes makes them firm enough to remove without cracking.

Mistakes To Avoid

Filling the shells too high causes the custard to overflow and the quiches to stick to the tin. Leave at least 1/4 inch of space at the top. The filling will puff slightly as it bakes, then settle as it cools.

Skipping the pre-bake step on the crust lets it absorb moisture from the filling and turn soft and pale instead of crispy. Even two minutes in a 400°F (200°C) oven makes a difference. The shells should look set but still pale.

Using pre-shredded cheese introduces anti-caking starch that makes the custard break or turn grainy. Grate the cheese fresh from a block, or use small fresh mozzarella balls if you prefer a softer texture.

Baking at a temperature above 400°F (200°C) browns the crust fast but leaves the center runny. Stick to 375°F (190°C) and give the quiches a full 20 to 25 minutes. They are done when the filling jiggles just slightly in the very center and the top is golden.

Ingredients

• 12 small pie dough rounds, 3 to 4 inches wide
• 6 large eggs
• 1/2 cup heavy cream
• 1/2 cup grated Gruyere cheese
• 1/4 cup grated sharp cheddar cheese
• 6 slices bacon, cooked and crumbled
• 1/2 cup fresh spinach, chopped
• 1/4 cup mushrooms, finely diced
• 1/4 teaspoon salt
• 1/8 teaspoon black pepper
• 1 teaspoon fresh thyme leaves
• 1 egg white, lightly beaten
• 1 tablespoon butter, for the tin

Step-by-step Instructions

1. Heat the oven to 400°F (200°C). Butter a 12-cup muffin tin lightly.
2. Line each cup with one pie dough round, pressing it gently into the bottom and sides without stretching it.
3. Brush each shell with a thin coat of beaten egg white to seal it.
4. Bake the shells for 2 minutes at 400°F (200°C), until they look set but are still pale. Remove and set aside.
5. Lower the oven to 375°F (190°C).
6. In a small bowl, whisk together eggs, cream, salt, pepper, and thyme until smooth.
7. Divide bacon, spinach, and mushrooms evenly among the shells, using about 1 tablespoon per quiche.
8. Pour the custard mixture into each shell until it reaches 1/4 inch below the rim, about 2 tablespoons per quiche.
9. Sprinkle Gruyere and cheddar evenly over the tops.
10. Bake at 375°F (190°C) for 20 to 25 minutes, until the filling is set at the edges and jiggles just slightly in the very center, and the tops are light golden.
11. Let the quiches cool in the tin for 5 minutes, then run a thin knife around each one and turn it out onto a wire rack.
