Ingredients

For the Crust:

• 1 ½ cups all-purpose flour (180g)
• ½ teaspoon salt
• ½ cup cold unsalted butter, cubed (113g)
• 4 to 5 tablespoons ice water

For the Filling:

• 2 tablespoons olive oil
• 8 ounces cremini mushrooms, finely chopped (225g)
• 2 cups fresh spinach, roughly chopped (60g)
• 3 cloves garlic, minced
• 6 large eggs
• 1 cup heavy cream (240ml)
• 1 cup shredded Gruyère cheese (100g)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ⅛ teaspoon ground nutmeg
• 2 tablespoons fresh chives, chopped

The combination of heavy cream and eggs creates that signature custard texture, while Gruyère adds sophisticated nuttiness. Cremini mushrooms provide deeper flavor than standard button varieties, though either works beautifully in these savory quiche cups.

Pro Tips

Master the Pastry: Cold butter is absolutely essential for flaky crust. Freeze your cubed butter for 10 minutes before incorporating it into flour, and handle the dough minimally to prevent gluten development. If the dough feels warm at any point, refrigerate it for 15 minutes before continuing. This temperature control creates those coveted flaky layers.

Remove Excess Moisture: Mushrooms release considerable liquid during cooking, which can create soggy quiche bottoms. Sauté your mushrooms over medium-high heat until they’ve released their moisture and the pan looks nearly dry. This concentrates flavor while preventing watery filling. Similarly, squeeze excess water from cooked spinach using a clean kitchen towel.

Prevent Soggy Bottoms: Blind bake your pastry shells for 8 to 10 minutes before adding filling. This partial pre-baking creates a moisture barrier that keeps crusts crisp even after adding the custard. Prick the bottom of each shell with a fork before baking to prevent puffing and bubbling during this initial bake.

Step-by-Step Instructions

Step 1: Prepare the Pastry Dough

Combine flour and salt in a large mixing bowl. Add cold, cubed butter and use a pastry cutter or your fingertips to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces still visible. Drizzle ice water one tablespoon at a time, mixing gently until the dough just comes together. Form into a disk, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes. This resting period allows gluten to relax and butter to firm up again.

Step 2: Prepare the Vegetable Filling

Heat olive oil in a large skillet over medium-high heat. Add chopped mushrooms and cook for 6 to 8 minutes, stirring occasionally, until they’ve released their moisture and begin to brown. Add minced garlic and cook for another minute until fragrant. Toss in chopped spinach and stir just until wilted, about 2 minutes. Transfer the vegetable mixture to a plate and let it cool completely while you prepare the muffin tins. This cooling step prevents the eggs from cooking prematurely when you combine everything.

Step 3: Roll and Cut the Dough

Preheat your oven to 375°F (190°C) and generously grease a 12-cup muffin tin. Roll the chilled dough on a lightly floured surface to about ⅛-inch thickness. Use a 4-inch round cutter to cut circles from the dough, rerolling scraps as needed. Gently press each circle into a muffin cup, making sure the dough comes up the sides and sits flush against the bottom. Prick the bottom of each pastry shell with a fork several times. Place the tin in the refrigerator for 10 minutes to firm up before the initial bake.

Step 4: Blind Bake the Crusts

Place the muffin tin in your preheated oven and bake for 8 to 10 minutes until the pastry just begins to look set but hasn’t browned. Remove from the oven and let the shells cool slightly while you prepare the custard mixture. This partial baking ensures your Spinach and Mushroom Quiche Muffins will have perfectly crisp bottoms rather than soggy, undercooked pastry.

Step 5: Make the Custard Mixture

Whisk together eggs and heavy cream in a large measuring cup or bowl until thoroughly combined and slightly frothy. Season with salt, pepper, and nutmeg, whisking again to distribute the spices evenly. The nutmeg adds a subtle warmth that complements the earthiness of the mushrooms beautifully, but use a light hand as it can quickly overpower other flavors.

Step 6: Assemble the Quiche Muffins

Divide the cooled mushroom and spinach mixture evenly among the 12 pastry shells, using about a tablespoon per muffin. Sprinkle shredded Gruyère cheese over the vegetables in each cup. Carefully pour the custard mixture into each shell, filling to just below the rim of the pastry. The filling will puff slightly during baking, so leave a small gap to prevent overflow. Garnish the top of each muffin with a pinch of fresh chives for color and added flavor.

Step 7: Bake Until Golden and Set

Return the muffin tin to the oven and bake for 22 to 26 minutes. The Mouthwatering Spinach and Mushroom Quiche Muffins are done when the centers are just set with only a slight jiggle, the tops are golden brown, and the edges pull away slightly from the pan. A toothpick inserted into the center should come out mostly clean with perhaps a few moist crumbs. Let the muffins cool in the pan for 5 minutes before carefully removing them with a butter knife or small offset spatula to a cooling rack.

Variations

Mediterranean Quiche Cups: Replace mushrooms with sun-dried tomatoes and add crumbled feta cheese instead of Gruyère. Include chopped kalamata olives and fresh oregano for an Italian-inspired twist that transports you straight to the Mediterranean coast.

Meat Lover’s Version: Add ½ cup cooked, crumbled bacon or diced ham to the vegetable mixture for a heartier breakfast option. The smoky, salty meat complements the earthy vegetables beautifully and adds satisfying protein that keeps you full longer.

Dairy-Free Adaptation: Substitute the heavy cream with full-fat coconut milk and use nutritional yeast instead of cheese. While the texture differs slightly from traditional quiche, these modifications create delicious plant-based mushroom and spinach quiche muffins that accommodate dietary restrictions without sacrificing flavor.

Storage and Serving

Store cooled Spinach and Mushroom Quiche Muffins in an airtight container in the refrigerator for up to 4 days. Reheat individual muffins in a 300°F oven for 8 to 10 minutes to restore crispness, or microwave for 30 to 45 seconds for a quick breakfast option. These quiche cups also freeze beautifully for up to 3 months. Wrap each muffin individually in plastic wrap, then place them in a freezer-safe bag. Thaw overnight in the refrigerator before reheating.

Serve these versatile muffins warm or at room temperature alongside a crisp green salad dressed with lemon vinaigrette for a light lunch. They’re equally delicious as part of a brunch spread with fresh fruit, smoked salmon, and mimosas. For breakfast on the go, wrap a quiche muffin in a napkin and pair it with a travel mug of coffee for a satisfying portable meal that beats any drive-through option.
