Step‑by‑Step Instructions for Mini Mushroom Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures the perfect baking environment for your mini mushroom quiches. While the oven heats, gather your ingredients and equipment, including mixing bowls, a rolling pin, a knife, and mini tart pans to streamline your cooking process.
Step 2: Prepare the Vegetables
Slice the mushrooms into thin pieces, mince the garlic finely, and dice the onion for your filling. Sautéing these together brings out their rich flavors, establishing the quiche’s savory appeal. Set the prepared vegetables aside as you prepare your dough.
Step 3: Make the Dough
In a mixing bowl, combine flour and salt, then slowly incorporate the oil and cold water until the mixture forms a thick dough. Be careful not to overwork the pastry, as this helps maintain a flaky texture. Once mixed, transfer it to a lightly floured surface for the next step.
Step 4: Divide and Shape the Dough
Split the dough into four equal parts, flattening each piece into a disc. Lightly press each disc into your mini tart pans, ensuring they cover the bottoms and sides evenly. The goal is to achieve a uniform thickness for a perfectly baked crust that will cradle your delicious filling.
Step 5: Sauté the Filling
Heat a skillet over medium heat and add a drizzle of olive oil. Add your sliced mushrooms and diced onions, cooking them until they become golden and fragrant, about 5-7 minutes. Stir in the minced garlic for the last minute of cooking, allowing its aroma to permeate the mixture before removing it from the heat.
Step 6: Prepare the Egg Mixture
In a separate bowl, beat the eggs until frothy, then whisk in the cream until the mixture is smooth. This combination creates the rich, custardy filling for your mini mushroom quiches. Ensure everything is well blended, and set the bowl aside while you assemble the quiches.
Step 7: Assemble the Quiches
Distribute the sautéed mushroom and onion mixture evenly across the crusts in your mini tart pans. Sprinkle the cheese on top, followed by the egg mixture, filling each quiche about three-quarters full to allow for expansion during baking.
Step 8: Bake the Quiches
Carefully place the mini quiches in the preheated oven and bake for 30-35 minutes, or until the edges are golden brown and the filling is set. You’ll know they’re done when a toothpick inserted in the center comes out clean, showcasing their perfect puffed texture.
Step 9: Cool and Serve
Once baked, remove the mini mushroom quiches from the oven and let them cool for 5-10 minutes. This cooling phase allows the filling to firm up slightly, making them easier to serve. Enjoy these delightful little bites warm, or at room temperature, perfect for any gathering!

How to Store and Freeze Mini Mushroom Quiche
Fridge: Keep your mini mushroom quiche in an airtight container in the fridge for up to 4 days. This will help maintain their fresh taste and texture.
Freezer: For longer storage, freeze the quiches in a single layer, placing parchment paper between layers to avoid sticking. They can last up to 3 months in the freezer.
Reheating: To reheat, bake in the oven at 350°F (175°C) for about 10-15 minutes until warmed through and crisp. Avoid the microwave to keep that delightful flaky crust.
Expert Tips for Mini Mushroom Quiche
- Sauté First: Always sauté mushrooms to remove excess moisture, as this prevents sogginess in your mini mushroom quiche.
- Dough Handling: Be gentle when mixing the dough; overworking can lead to a tough crust. Keep it flaky for the best texture.
- Fill Smartly: Fill your quiches only 3/4 full to avoid spilling over while baking—this keeps the oven tidy and the presentation neat.
- Storage Savvy: If you’re making quiches ahead of time, store them in an airtight container; they’ll stay fresh for up to 4 days in the fridge.
- Reheat Right: Reheat your mini mushroom quiche in the oven to maintain the crust’s crispness, instead of using the microwave which can make it soggy.

Mini Mushroom Quiche Recipe FAQs
How do I select the best mushrooms for my mini mushroom quiche?
Absolutely! For the best flavor and texture, choose fresh Baby Bella or Cremini mushrooms. Look for firm mushrooms without dark spots or wrinkles. If you can’t find those, white button mushrooms are a great substitute. Always opt for mushrooms that are dry to the touch and have a pleasant earthy aroma.
What’s the best way to store leftover mini mushroom quiches?
Very! Store your mini mushroom quiches in an airtight container in the fridge, where they can stay fresh for up to 4 days. To keep them at their best, ensure they are completely cool before sealing them up. You can also wrap individual quiches in plastic wrap for ease of serving later on!
Can I freeze my mini mushroom quiches?
Absolutely! To freeze, first let the quiches cool completely, then place them in a single layer with parchment paper between each layer to prevent sticking. They can be frozen for up to 3 months. When you’re ready to enjoy them, just reheat in the oven at 350°F (175°C) for about 10-15 minutes, or until warmed through and crispy.
What should I do if my quiche filling is too watery?
Oh no! If your filling ends up too watery, be sure to always sauté the mushrooms beforehand to reduce their moisture content. If you’ve skipped that step, consider adding a bit of cornstarch or flour to thicken the mixture in the egg mixture. Another option is to drain any excess liquid before pouring it into the crust.
Can I make mini mushroom quiche for someone with a dairy allergy?
Absolutely! For a dairy-free alternative, you can use a non-dairy milk such as almond or soy milk in place of cream, and opt for dairy-free cheese. This makes your mini mushroom quiche adaptable for anyone with dietary restrictions without sacrificing flavor!
How do I reheat mini mushroom quiche without losing its crust’s flaky texture?
Very nice question! To reheat while keeping that lovely flaky texture, place the quiches in a preheated oven at 350°F (175°C) for about 10-15 minutes. This method warms them thoroughly while crisping the crust, making sure your mini mushroom quiche is just as delightful as when you first baked it!
