These mini tartlets marry the deep sweetness of caramelized onions with the earthy richness of sautéed mushrooms, all finished off with a hint of maple. Flaky puff pastry cups the filling, creating an elegant bite that’s both irresistibly sweet and comfortingly savory.
Ingredients
- 1 tablespoon olive oil
- 1 tablespoon butter
- 2 large yellow onions, thinly sliced
- 1 teaspoon salt, divided
- 2 cups sliced mushrooms (portobello, cremini, or button)
- 1 tablespoon fresh thyme leaves (plus extra for garnish)
- 2 tablespoons maple syrup
- 1 sheet puff pastry, thawed
- Freshly ground black pepper to taste
Instructions
Begin by caramelizing the onions. Warm the olive oil and butter together in a skillet over medium-low heat. Add the sliced onions and half of the salt, stirring occasionally until the onions turn golden brown and melt-in-your-mouth tender, about 25 minutes. If they begin to brown too quickly, reduce the heat to low and stir more frequently.
Once the onions are caramelized, increase the heat to medium, then add the mushrooms and the remaining salt. Sauté until the mushrooms release their liquid and become soft and lightly browned, about 5 to 7 minutes. Stir in the fresh thyme and a drizzle of the maple syrup, letting it coat the onions and mushrooms for extra sweetness.
Meanwhile, preheat your oven to 400°F (200°C). Roll out the thawed puff pastry sheet and cut it into squares or circles (depending on your preference) to fit into miniature tartlet pans or a muffin tin. Press each puff pastry piece into the pan or muffin cup, shaping it gently along the sides.
Spoon the caramelized onion and mushroom mixture into each pastry cup. Drizzle the remaining maple syrup on top, then finish with freshly cracked black pepper. Bake for 15 to 18 minutes, or until the edges of the puff pastry turn golden and crispy. Let cool slightly before carefully removing from the pan.
These Maple-Glazed Caramelized Onion & Mushroom Tartlets deliver a warm, comforting savoriness balanced by subtle sweetness. They’re perfect for dinner parties, as an elegant appetizer, or simply when you crave something tasty and a touch indulgent. If you’d like a lighter take, reduce the amount of butter or replace with extra olive oil. Feel free to experiment with different herbs (like rosemary or sage) or add a sprinkle of cheese (goat cheese or feta) for extra complexity. Enjoy these versatile bites as a charming addition to your table—sweet, savory, and altogether delightful.
