These puff pastry tarts are so easy to make as an appetizer or main course. Topping pre-made puff pastry with mushrooms that have been sautéed in a delicious balsamic bath and then layered on melty cheese, these tarts are hard to beat!

The weekend is rolling in and I’m making a buttery, light, airy puff pastry with balsamic glazed shallots and mushrooms, and a sprinkle of gruyére cheese. It’s like an ultra-adult pizza that is LITERALLY wine’s best friend. Can I suggest a tall glass of pinot noir?
I’ve served this as an appetizer and as an entrée. You choose! You can’t go wrong.

Balsamic Glazed Mushroom Tart
Ingredients
- 2 cups cremini mushrooms, sliced (they’re also called baby bella mushrooms!)
- 7 ounces good-quality puff pastry dough, cut into 2 rectangles
- 5 ounces gruyere, jarlsberg or emmenthaler cheese, grated
- 3 shallots, cut into rings
- 1 clove garlic, minced
- 3 tablespoons butter
- 2 tablespoons balsamic vinegar
- 2 teaspoons soy sauce
- ½ teaspoon dark brown sugar
- 4 sprigs fresh thyme
Instructions
- Preheat oven to 375 degrees.
- Lay puff pastry dough rectangles on a greased baking sheet. Sprinkle both rectangles with a generous layer of cheese, leaving a crust-like border around the outside of the pastry with no cheese.
- In a large skillet over medium heat, melt butter. Add mushrooms, shallot rings, garlic, dark brown sugar, soy, and balsamic. Stirring often, let mushroom mixture cook and soften for 8-10 minutes until mushrooms shrink to about half of their original size and the shallots soften and begin to caramelize. Turn the burner off and stir in thyme removed from 2-3 sprigs.
- Use a slotted spoon to add mushroom mixture to the top of each pastry, leaving a border around the outside of each pastry uncovered.
- After all mushroom mixture is used, sprinkle the top of each pastry with more cheese and a bit more thyme.
- Crimp the edges of the pastries with fork (if you’d like to make these extra pretty!).
- Bake for 21-26 minutes until pastries are golden brown. Let rest for 5 minutes before enjoying (with wine, of course!).

Would these work in phyllo shells instead of puff pastry?
Absolutely yes! I love this idea. I’d follow the directions on the phyllo shell package for baking.

Thank you. Some family members are gluten free and this would be a great substitution to appease them. 🙂
Love it! Let me know how they turn out!

This is my go-to recipe now for last minute potluck dinners, quick entertaining and super-fast, super-flavorful after-church brunches. I’ve made this with baby Bellas, white cremini and other types of mushrooms and once, in a piece, substituted yellow and green squash (omiting the balsamic, sugar and soy) successfully. I’ve used whatever cheese I have on hand (fontina, mozzarella, asiago) and each time I’ve gotten rave reviews and people begging for the recipe. I think it’s the most-requested dish I’ve brought to take-alongs!
This makes me so happy to hear! I love all of the different variations. Thanks for letting me know!

Does this recipe reheat well? I would love to fully bake and reheat for a party.
Hi! I have made these ahead and they keep quite well, reheating them in the oven. Enjoy!
Tried this last night for dinner. Had wonderful mushrooms from a local grower (R & R Cultivation if you are in Mpls/St Paul Area) and puffy pastry in the freezer. It was an easy recipe and it came together quickly. The addition of the balsamic vinegar, soy sauce and brown sugar elevated the flavor. I have made similar recipes but this one is the most flavorful and we will be making this often! Great recipe to share. Thanks!
Hi Shannon,
I am so happy to hear you loved the tart! It is one of my favorites. I wish I could try some of those local mushrooms with it. 🙂

Made this last night for dinner and still thinking about it this morning! It was absolutely delicious and so easy to make. The combination of cheese, mushrooms and cartelized onions (shallots, who knew?) was perfection. It was on the table in no time. I served it with an Arugula Salad (cut dried figs, goat cheese and pine nuts, that’s it!) added a fig balsamic dressing on top. Making this Tart again, soon!
Hi Lisa,
Thanks so much for the comment! I am thrilled that you loved the tart. It is one of my favorite recipes! Let me know if you try any others.
Grace
Perfect! Thank you so much Grace
Anytime! Hope you enjoy 🙂
I was wondering if the filling could be made a day ahead
Hi Kathy!
You can definitely make the mushroom mixture the day ahead. Keep it in an airtight container in the fridge and warm in the microwave right before you want to fill and bake the tarts! I recommend filling the tarts the day-of so the puff pastry doesn’t get soggy!
Grace
thanks s much Grace – these all sound like lovely additions to a perfect lunch
So happy to help!

I am going to serve these to 7 friends for a birthday luncheon but I would like to add something on the side to go with . . . any suggestions other than the traditional little salad?
Hi Carole,
Thanks for your comment! Great question. I have a few ideas. You could roast some pearl onions with some olive oil and toss in some sweet peas and fresh herbs. You could also place some prosciutto, cherry tomato and basil (and fresh mozz if you prefer) on toothpicks or skewers. Or you could make a fun salad with arugula or spinach, candied walnuts and pecorino with a simple balsamic or white balsamic vinegar dressing! My final idea is you could serve with slow roasted campari tomatoes and some roasted asparagus with meyer lemon juice and shaved parmigiano on the top! Let me know if you need more details for one of these ideas! I hope this helps!

This recipe is awesome for many reasons. It is easy to prepare – I already had most of the ingredients, nothing fancy that you won’t use again, and the end result is absolutely DELCIOUS!! I can’t wait to serve this to friends. Sooo… good!!
Hi Jodi,
