Ingredients You’ll Need
Here’s a breakdown of the stars of this savory show:
Caramelized Onions – Slow-cooked until golden and sweet, these give the tart a rich depth of flavor.
Baby Bella Mushrooms – Earthy and hearty, they add a nice umami balance. Just be sure to remove any big stems and cut larger pieces in half.
Bacon – Because… bacon. It adds a smoky, salty bite that ties all the flavors together.
Brussels Sprouts – Thinly chopped and sautéed for a slight crisp. Roasting them with bacon elevates their flavor and adds some great texture to the tart.
Red Table Grapes – Yes, grapes! When roasted, they become sweet and jammy—an unexpected but delicious ingredient in this savory tart.
Parmesan Cheese – Freshly grated is best. The saltiness and nuttiness are the perfect finishing touch.
Puff Pastry & Egg Wash – Store-bought puff pastry keeps this recipe easy. The egg wash gives the tarts that perfect golden finish.
What to Serve with These Grape & Brussels Sprout Tarts
These mini tarts are perfect for a variety of occasions. Serve them with:
- A holiday cheese board or charcuterie platter
- A crisp glass of white wine (like Sauvignon Blanc or Pinot Grigio)
- A side of roasted nuts or spiced olives
- As a starter before a roast chicken or beef dinner
They’re also fantastic at brunch alongside a simple salad and a mimosa!
How to Store Leftovers
While these puff pastry tarts are best fresh out of the oven, you can save leftovers:
- Store in an airtight container in the fridge for up to 3 days.
- Reheat in a 350°F oven for 8–10 minutes to revive the flakiness.
- Avoid microwaving if possible—it makes the puff pastry soft instead of crisp.

Ingredients
Caramelized Onion & Mushroom Mixture
- 1/2 onion, thinly sliced
- 1 tsp salt
- 1 tbsp vegetable oil
- 1 tbsp butter, divided
- 4 oz. baby bella mushrooms, sliced, large stems removed and mushrooms halved
Bacon & Brussels Sprouts
- 2 slices of bacon cooked and crumbled.
- 10 Brussels sprouts, quartered (chop again if extra large)
- 1 tbsp butter
Grape & Cheese Mixture
- 1/2 cup red table grapes, quartered
- 2 tsp sugar
- 1/2 cup freshly grated Parmesan cheese
Tart Base:
- 2 sheets puff pastry, thawed
- 1 egg, beaten (for egg wash)
Instructions
- Caramelize the Onions:
In a large frying pan, heat the vegetable oil over medium heat. Add the sliced onion, salt, and butter. Cook, stirring occasionally, until the onions are soft and caramelized—about 15 minutes. Transfer to a mixing bowl. - Cook the Mushrooms:
In the same pan, add 1/2 tablespoon butter and sauté the mushrooms for about 5 minutes. Transfer to the bowl with the onions. - Prepare the Bacon & Brussels Sprouts:
Increase heat to medium-high. Cook the bacon until crisp. Remove, drain grease, and crumble. Return bacon to the pan with the butter and Brussels sprouts. Stir-fry for about 8 minutes, then add to the mixing bowl. - Add Grapes & Cheese:
Add quartered grapes, sugar, and Parmesan cheese to the bowl. Mix everything together until well combined. - Cut the Puff Pastry:
Roll out each puff pastry sheet. Use a ruler to mark every 2 inches along both edges. Cut into 2x2-inch squares using a pizza cutter. You should get about 25 squares per sheet. - Assemble the Tarts:
Place puff pastry squares on a baking sheet. Brush with egg wash. Spoon a small amount of the mixture onto the center of each square. Use your fingers or a spoon to gently press the filling into a mound. - Bake: at 400°F (200°C) for 12–13 minutes or until the pastry is golden and puffed. Serve warm.
