I first made this brie and mushroom tart on a lazy Sunday when I wanted something that looked fancy but didn’t actually take much effort. I roasted a mix of mushrooms until they turned deep golden and jammy, layered them over crisp puff pastry, and finished everything with melty pools of brie.
The smell alone had everyone in my kitchen before it even came out of the oven. It’s become my go-to whenever I need an appetizer that feels special without a long ingredient list.
Cooking Time
- Prep Time: 15 minutes
- Cooking Time: 40 minutes
- Total Time: 55 minutes
Ingredients
- 12 oz mixed mushrooms (cremini, shiitake, king oyster) – a mix gives you different textures, so don’t just grab one type
- 1/2 cup thinly sliced shallots – they turn sweet and soft as they roast alongside the mushrooms
- 1 tbsp extra-virgin olive oil – helps everything roast evenly instead of steaming
- 1 tbsp balsamic vinegar – adds a little tang that balances the richness of the cheese
- 1 1/2 tsp Dijon mustard – gives the mushrooms a subtle savory depth
- 1 clove garlic, minced – use fresh garlic here, not the jarred kind, for real flavor
- 1/2 tsp dried thyme (or 1 1/2 tsp fresh) – fresh thyme makes a noticeable difference if you have it
- 1/4 tsp salt – season early so the mushrooms don’t taste flat
- 1/4 tsp coarse black pepper – coarse pepper gives a little bite in every mouthful
- 1/2 sheet (about 8 oz) frozen puff pastry, thawed – keep it cold until you’re ready to roll it out
- 1/2 cup diced brie cheese – freeze it for a few minutes first so it dices cleanly
- 2 tbsp chopped fresh parsley – adds color and a fresh finish right before serving
Note: this recipe serves 4 to 8, depending on whether you’re plating it as an appetizer or a light main.
Equipment You Need
- Rimmed baking sheet – roasts the mushrooms evenly and catches any juices
- Parchment paper – keeps the pastry from sticking and makes cleanup easy
- Rolling pin – for shaping the puff pastry into an even rectangle
- Mixing bowl – to toss the mushrooms with the oil and seasonings
- Fork – for pricking and crimping the pastry edges
- Sharp knife – for slicing the roasted mushrooms and cutting the finished tart
How to Make Brie and Mushroom Tart Recipe?
This tart comes together in three simple stages: roasting the mushrooms, baking the pastry base, then bringing everything together with the cheese. None of the steps are complicated, and most of the time is hands-off while things are in the oven. Here’s exactly how I do it.
Roast the Mushroom Mixture
I start by whisking the olive oil, balsamic vinegar, mustard, garlic, thyme, salt, and pepper together in a bowl. Then I toss in the mushrooms and shallots until every piece is coated. I spread them in a single layer on a parchment-lined baking sheet so they roast instead of steam.
Bake Until Golden
Into a 400°F oven they go for about 10 to 15 minutes, just until the mushrooms soften and pick up some color. I let them cool slightly before slicing, since warm mushrooms are tricky to cut neatly and tend to fall apart.
Prepare the Puff Pastry Base
While the mushrooms roast, I roll the thawed pastry into a rectangle on a lightly floured surface. I fold the edges over slightly and crimp them with a fork to form a little border, then prick the center all over so it doesn’t puff up too much in the oven.
Pre-Bake the Pastry
I bake the pastry alone for about 15 minutes, just until it turns light golden. This step matters because it keeps the base crisp once the toppings go on, instead of turning soggy underneath the mushrooms.
Add the Toppings and Bake Again
Once the base is ready, I top it with the roasted mushroom mixture, leaving behind any extra liquid so the pastry stays crisp. I scatter the diced brie generously over the top and slide it back into the oven for another 15 minutes, until the cheese melts and the edges turn deep golden.
Cool, Garnish, and Serve
I let the tart rest for about 10 minutes before slicing, which helps the cheese set just enough to hold its shape. A scattering of fresh parsley right before serving adds a nice pop of color and a fresh finish.
Additional Tips for Making This Recipe Better
I’ve made this tart enough times to pick up a few tricks that make it turn out better every time.
- I always freeze my brie for about 15 minutes before dicing it, since it’s so much easier to cut cleanly when it’s firm.
- I make sure to leave the mushroom liquid behind on the baking sheet, or the pastry base turns soggy.
- I like to pat my mushrooms dry before tossing them in oil, since wet mushrooms don’t roast as well.
- I keep my puff pastry cold until the last possible moment, which helps it puff up nicely in the oven.
- I always pre-bake the pastry base fully before adding toppings, since a half-baked base just can’t support the weight of the mushrooms and cheese.
Common Mistakes to Avoid
- I’ve overcrowded my mushrooms on the baking sheet before, and they ended up steaming instead of roasting, so I always give them plenty of space now.
- I once skipped pricking the pastry dough, and it puffed up unevenly, so I never skip that step anymore.
- I’ve learned not to add the cheese too early, since it can burn before the pastry finishes baking.
- I made the mistake of slicing the tart while it was piping hot once, and the cheese just oozed everywhere, so I let it rest for at least 10 minutes now.
- I used to skip drying my mushrooms after washing them, which watered down the flavor, so I always pat them dry first.
How to Serve Brie and Mushroom Tart?
I like to cut this tart into small squares or rectangles for an appetizer spread, or larger pieces if I’m serving it as a light main course with a salad on the side. A few extra thyme leaves or a light drizzle of honey over the melted brie makes it look more polished on a serving board.
Pairing it with a simple arugula salad dressed in lemon and olive oil gives a nice contrast to the richness of the pastry and cheese. If I’m hosting, I serve it warm straight from the oven, since that’s when the brie is at its gooiest and most appealing. You can also enjoy similar flavors in a creamy pasta dish with creamy brie pasta recipe when you’re in the mood for something comforting.
Variations
- Swap the brie for creamy goat cheese or a wedge of blue cheese for a sharper, tangier flavor.
- Use paneer instead of brie for a milder, dairy-forward option that holds its shape well.
- Add a thin layer of caramelized onions under the mushrooms for extra sweetness.
- Try a mix of wild mushrooms if you want a more intense, earthy flavor.
- Sprinkle on toasted walnuts or pine nuts for some crunch.
- Use fresh rosemary instead of thyme for a slightly different herb profile.

Make Ahead and Storage
You can roast the mushroom mixture up to a day in advance and keep it covered in the fridge until you’re ready to assemble the tart. This saves time if you’re prepping for guests.
Once baked, leftovers keep well in an airtight container in the fridge for up to 2 days. The pastry does soften over time, so it’s best enjoyed within that window. To reheat, pop the tart in the oven or toaster oven for a few minutes until the pastry crisps back up and the cheese softens again.
I don’t recommend the microwave, since it makes the pastry chewy instead of flaky. A similar combination of mushrooms and brie also works beautifully in a brie and mushroom pasta recipe for a cozy meal.
Why You’ll Love This Recipe?
This tart has earned a permanent spot in my appetizer rotation, and here’s why I think you’ll love it too.
- It looks impressive but is genuinely simple to put together, which makes it perfect for both weeknights and dinner parties.
- The combination of earthy mushrooms and creamy brie feels indulgent without being heavy.
- It’s easy to customize with different cheeses, herbs, or mushroom varieties depending on what I have on hand.

- It’s a great make-ahead option since the mushrooms can be roasted a day early.
FAQs
Can I use a different cheese in this mushroom and brie tart recipe?
Yes, blue cheese or soft goat cheese both work well as substitutes. They bring a similar creamy texture with a slightly different flavor profile.
Is this brie tart recipe similar to a Mary Berry mushroom tart recipe?
It shares the same idea of mushrooms on puff pastry, but this version leans into balsamic and brie for a richer, tangier finish rather than a classic British-style filling.
Can I turn this into a mushroom and blue cheese tart recipe instead?
Absolutely, just swap the brie for an equal amount of crumbled blue cheese. It adds a sharper, more pungent flavor that pairs beautifully with the roasted mushrooms.
Can I make this tart ahead of time?
Yes, roast the mushrooms a day ahead and store them in the fridge, then assemble and bake the tart fresh when you’re ready to serve.
Why did my puff pastry turn out soggy?
This usually happens when the mushroom liquid isn’t drained before topping the pastry, or when the base isn’t pre-baked long enough before adding the toppings.
