Step‑by‑Step Instructions for Mini Mushroom & Gruyère Pot Pies
Step 1: Preheat and Prepare Ramekins
Begin by preheating your oven to 200°C (400°F). While the oven heats, generously grease six ramekins with butter or oil, ensuring they’re well-coated to prevent sticking. This preparation is essential for giving your Mini Mushroom & Gruyère Pot Pies a perfectly golden and flaky finish.
Step 2: Sauté Aromatics
In a medium skillet, heat 2 tablespoons of unsalted butter and 1 tablespoon of olive oil over medium heat. Add the finely chopped shallot and sauté for about 3-4 minutes until it becomes translucent. Then, stir in the minced garlic, cooking for an additional minute until fragrant, infusing your filling with warmth and depth.
Step 3: Cook the Mushrooms
Now, add the mixed sliced mushrooms to the skillet. Sauté them for approximately 5-7 minutes, or until the mushrooms release their moisture and start to brown. Season this mixture with fresh thyme leaves, salt, and black pepper to taste, allowing the earthy flavors to harmonize beautifully.
Step 4: Create the Sauce
Sprinkle 3 tablespoons of all-purpose flour over the mushroom mixture, stirring for about 1 minute to cook the flour slightly. Gradually pour in ½ cup of dry white wine, allowing it to simmer and reduce until nearly evaporated, which should take about 2-3 minutes, intensifying the flavors in your Mini Mushroom & Gruyère Pot Pies.
Step 5: Finish the Filling
Next, add 1 cup of whole milk to the skillet, stirring continuously until the mixture thickens—this will take around 3-5 minutes. Remove the skillet from heat and stir in 1 cup of grated Gruyère cheese and Dijon mustard, allowing the cheese to melt into the creamy filling. Let it cool slightly while you prepare the pastry.
Step 6: Prepare Puff Pastry
On a lightly floured surface, roll out the thawed puff pastry until it’s about 1/8-inch thick. Using a round cutter or a plate, cut out six rounds that are slightly larger than your ramekins. These will form the delightful tops of your Mini Mushroom & Gruyère Pot Pies.
Step 7: Assemble the Pies
Carefully fill each greased ramekin with the mushroom mixture, distributing it evenly among them. Top each ramekin with a round of puff pastry, ensuring to seal the edges well by pinching them together. Cut a small slit in the center of each pastry to allow steam to escape while baking.
Step 8: Add Finishing Touches
Brush the tops of the pastries generously with a beaten egg to achieve that beautiful golden color during baking. Sprinkle a few extra thyme leaves over each pie for added flavor and visual appeal, making your Mini Mushroom & Gruyère Pot Pies even more inviting.
Step 9: Bake to Perfection
Place the assembled pot pies on a baking sheet and bake them in the preheated oven for 18-22 minutes, or until the pastry is golden brown and puffed up. Keep an eye on them towards the end to ensure they reach that perfect crispy texture.
Step 10: Serve and Enjoy
Once baked, remove the Mini Mushroom & Gruyère Pot Pies from the oven and let them cool for about 5 minutes. This waiting time ensures the filling sets a bit, making them easier to enjoy. Serve warm, allowing the delightful aroma to fill your kitchen as you indulge in these comforting bites!

Make Ahead Options
These Mini Mushroom & Gruyère Pot Pies are perfect for meal prep enthusiasts! You can prepare the filling up to 3 days in advance by cooking it as directed, letting it cool, and then refrigerating it in an airtight container. The puff pastry can be rolled and cut into rounds ahead of time; just store the rounds in the fridge for up to 24 hours. When you’re ready to serve, simply assemble the pot pies, top with pastry, and bake as instructed. This way, you’ll have a cozy, restaurant-quality meal ready to go with minimal effort on busy weeknights!
