Ingredients You’ll Need
Everything you need for these pot pies is pretty straightforward, but don’t let the simplicity fool you—each ingredient adds a layer of deliciousness, from the earthiness of mushrooms to the buttery, melt-in-your-mouth pastry. Here’s what you’ll need, along with a note on why each is so wonderful in Mini Mushroom & Gruyère Pot Pies with Thyme:
- Unsalted butter: Adds richness and helps build flavor as you sauté the vegetables.
- Olive oil: A touch of olive oil keeps the butter from burning and gives a subtle fruity note.
- Onion: Provides sweetness and depth as the base for your filling.
- Garlic: Lends a warm, fragrant kick to balance the dish.
- Mixed mushrooms: Use your favorites—cremini, button, shiitake—for texture and savory, umami intensity.
- Fresh thyme leaves: The star herb for that aromatic, floral lift.
- All-purpose flour: Thickens the sauce to create a creamy, luscious filling.
- Vegetable or chicken stock: Adds savoriness and keeps the filling velvety without being heavy.
- Heavy cream: Makes everything dreamy and indulgent—essential for that “wow” factor.
- Salt and pepper: The basics, but don’t underestimate what proper seasoning brings to the party.
- Gruyère cheese: Melty, nutty, and a little bit fancy—Gruyère ties everything together.
- Puff pastry sheet: Puffs up into a crisp, golden crown on each pie. Ready-made makes prep a breeze!
- Egg (for wash): Brushing the pastry with egg gives each pot pie that irresistible glossy finish.
How to Make Mini Mushroom & Gruyère Pot Pies with Thyme
Step 1: Sauté the Vegetables
Start by heating butter and olive oil in a large skillet over medium heat. Add the finely chopped onion and minced garlic, cooking until their wonderful aromas fill your kitchen and the onion becomes soft and translucent. Next comes the mushrooms and a scatter of fresh thyme—allow them to cook down until golden and just a bit caramelized. Don’t rush this step! It’s where so much of the savory flavor develops for your Mini Mushroom & Gruyère Pot Pies with Thyme.
Step 2: Thicken the Filling
Sprinkle the flour right over your mushroom mixture and stir for a minute, letting it soak up all those flavorful juices. Now, slowly pour in your stock, stirring constantly as the mixture thickens into a silky sauce. Once thickened, reduce the heat and stir in the heavy cream and half your Gruyère cheese. Season generously with salt and pepper. The mixture should be glossy and almost spoonable—if it looks too thick, feel free to add a little more stock for the perfect consistency.
Step 3: Prepare the Pastry & Assemble
Unroll the thawed puff pastry and cut circles slightly larger than the tops of your mini ramekins. Lightly grease your ramekins, then spoon in the still-warm (but not hot) mushroom filling. Cover each ramekin with a pastry circle, gently pressing the edges to seal and trimming off excess. For that irresistible bakery-style look, brush the tops with beaten egg and use a sharp knife to cut a small slit in the center. This allows steam to escape and keeps your Mini Mushroom & Gruyère Pot Pies with Thyme beautifully crisp on top.
Step 4: Bake to Golden Perfection
Arrange the filled ramekins on a baking sheet—this makes it easy to transfer them in and out of the oven. Bake at 200°C / 400°F for 20–25 minutes, or until the pastry is puffed up and deep golden brown. You’ll know they’re ready when you see bubbling cheese through the steam vents and the crust almost begging to shatter under your fork. Let them cool for about five minutes to avoid molten filling burns, then get ready to dig in!
Step 5: Garnish & Serve
Sprinkle the remaining Gruyère over the hot pot pies, letting the residual heat melt it into gooey bliss. Top with a few more fresh thyme leaves for a pop of color and that herbaceous finish. Now your Mini Mushroom & Gruyère Pot Pies with Thyme are table-ready!
How to Serve Mini Mushroom & Gruyère Pot Pies with Thyme

Garnishes
A little extra Gruyère grated on top while the pies are hot is always a good idea, as is a sprinkle of fresh thyme. For added flair, try a pinch of flaky sea salt or even a few drops of truffle oil. These little touches not only enhance flavor but also make each serving feel special.
Side Dishes
Pair these pot pies with a bright, lightly dressed green salad to balance the rich and creamy filling. Oven-roasted root vegetables like carrots and parsnips are spot-on for chilly days, while a bowl of simply steamed green beans with lemon zest brings freshness to the meal. The pies shine as a main dish, so keep the sides clean and simple.
Creative Ways to Present
For a rustic look, bake and serve the pies in mismatched vintage ramekins. For a crowd, set up a mini pot pie “bar” with a selection of cold salads and let guests choose their own garnishes. If you’re entertaining, tie twine around the ramekins for a homey touch or add edible flowers for a truly elegant twist. However you present them, Mini Mushroom & Gruyère Pot Pies with Thyme are sure to steal the show.
Make Ahead and Storage
Storing Leftovers
Leftover pot pies keep beautifully in the fridge. Simply cover each cooled ramekin tightly with foil or plastic wrap, and store them for up to three days. The pastry will soften a bit, but the savory flavor only gets better as everything melds together.
Freezing
To freeze, assemble the Mini Mushroom & Gruyère Pot Pies with Thyme right up to the point of baking. Wrap ramekins well with plastic and foil, label, and freeze for up to a month. When ready to bake, add about five extra minutes to the oven time and ensure the filling is piping hot all the way through.
Reheating
For best results, reheat leftover pies in a 180°C / 350°F oven for 15–20 minutes until the pastry crisps up again and the filling is hot. Microwaving is quick for lunches, but you’ll miss out on that glorious, flaky crust—so opt for the oven when you can.
FAQs
Can I use different types of mushrooms?
Absolutely! Feel free to experiment with a mix of cremini, button, portobello, shiitake, or even oyster mushrooms. A blend creates great depth, and you can adjust according to your favorites or what’s in season.
Is there a good substitute for Gruyère?
If Gruyère isn’t available, try Swiss cheese, fontina, or even sharp white cheddar. Each brings a different twist, but all will melt beautifully and complement the mushrooms and thyme.
Can I make these pot pies in advance?
Yes! You can fully assemble Mini Mushroom & Gruyère Pot Pies with Thyme ahead of time and refrigerate them covered for up to 24 hours. Bake just before serving for ultimate freshness and flakiness.
How do I make this vegetarian?
Just use vegetable stock instead of chicken stock, and make sure your puff pastry is made without animal fats. That’s all it takes to keep these pot pies meat-free and delicious!
What if I don’t have ramekins?
No worries! Use ovenproof mugs, small bowls, or even a muffin tin for mini pot pies. Just adjust pastry circles and watch the bake time, as smaller pies may cook a little faster.
Final Thoughts
