    This Savory Roasted Sweet Potato and Mushroom Tart is a simple yet impressive fall appetizer. This puff pastry tart appetizer combines roasted sweet potatoes, caramelized mushrooms and tangy goat cheese for a handheld appetizer that everyone will love. 

    A rectangular tart with golden pastry, topped with sliced orange sweet potatoes and dark caramelized onions. The tart is placed on a white surface, accompanied by fresh herbs and a few raw sweet potato slices.

    Roasted sweet potatoes have become on of my favorite vegetables. They are so versatile. I love to use them on top of salads, in tacos and in desserts. This recipe combines roasted sweet potatoes with savory mushrooms on a buttery puff pastry tart for an impressive appetizer. 

    Appetizers are my favorite food course! If you need more appetizers that are simple yet impressive, try this Cherry Tomato and Ricotta Toast. Sweet cherry tomatoes are roasted until they are near bursting and then served over a sweet whipped ricotta cheese. These little toasts are the perfect handheld bite! Another fun appetizer with whipped cheese is this Lemon Roasted Cauliflower with Whipped Mascarpone. This recipe is so flavorful and fun to serve at the holidays.

    Why You'll Love This Recipe

    • Puff Pastry, need I say more?! Using a puff pastry is the easiest way to elevate an appetizer. Store-bought puff pastry will save you time and results with a perfectly light pastry. 
    • Simple. This recipe can be made in about 10 minutes of hands on time. 
    • Full of flavor. Tangy goat cheese, balsamic mushrooms and roasted sweet potatoes are combined to make a perfectly savory treat. 

    Sweet Potato and Mushroom Tart Ingredients

    • Sweet potatoes are tossed with extra virgin olive oil and then roasted for a sweet flavor.
    • Chopped mushrooms are caramelized in butter and then tossed with balsamic vinegar for a deep, buttery flavor. 
    • Puff pastry is covered with goat cheese and an egg wash for an extra buttery, high gloss crust. Jus-Rol Puff Pastry is my favorite to use!
    • Fresh thyme ​tops the puff pastry and is added for extra flavor after the pastry bakes. 

    The exact measurements are listed below in the recipe card.

    Substitutions

    • A simple swap for the sweet potatoes is roasted butternut squash or roasted carrots. Not only do these vegetables share the same orange hue, they also have similar textures and flavors when roasted. 
    • Use a mushroom mixture! I like to use cremini mushrooms or sliced shitake mushrooms for this recipe. Use your favorite mushroom. 
    • Ricotta cheese or mascarpone cheese could be used in place of the goat cheese. These cheeses spread easily like the goat cheese. 
    • If you can't find a puff pastry, you can roll out a tube of crescent rolls.

    Variations

    • Add some protein! Crumbled turkey sausage would add some flavor that will compliment the sweet potatoes. 
    • Add vegan protein! Add some roasted chickpeas or black beans on top of the tart dough for some extra protein. 
    • Make this appetizer gluten-free by using a gluten-free puff pastry. 

    Equipment

    • Rimmed baking sheet 
    • Parchment paper. I like to use the parchment paper that the puff pastry is rolled in
    • Small bowl to make the egg wash
    • Large sauté pan to caramelize the mushrooms
    • Pastry brush 

    Step-by-Step Instructions

    A rectangular sheet of puff pastry is laid flat on a baking tray lined with parchment paper. The pastry has fork-pricked holes and a scored border, ready for baking. The background includes a partial view of a wooden surface and green foliage.

    Step 1: Roll out the puff pastry on parchment paper on a rimmed baking sheet. Use a knife to scour the edges. Use a fork to prick hole all over the puff pastry. 

      A bowl filled with sliced, seasoned sweet potatoes on a white surface, with a few slices arranged outside the bowl. A textured white cloth is partially visible in the background.

      Step 2: ​Toss sliced sweet potatoes with extra virgin olive oil, salt and black pepper. 

        Sliced mushrooms sautéing in a black skillet, showing a rich, golden-brown color with a light sheen from cooking.

        Step 3: Heat a tablespoon butter in a large sauté pan over medium high heat. Add mushrooms in an even layer. Cook undisturbed for 3-4 minutes and then flip over. Cook for another 3-4 minutes. The mushrooms should become a golden brown color. Remove from heat and stir in the balsamic vinegar. 

        Slices of sweet potatoes and mushrooms are arranged on a sheet of pastry dough with a creamy spread, ready for baking on a parchment-lined baking sheet.

        Step 4: Spread goat cheese over the middle of the puff pastry. Sprinkle with fresh thyme. Place sliced sweet potatoes and caramelized mushrooms in a single layer over the goat cheese. Using a pastry brush, paint the egg wash on the corners of tart shell. Bake for 20-25 minutes at 425 degrees Fahrenheit until the crust is a golden brown color.

          Storage

          Store any leftover tart refrigerated in an airtight container. Reheat in a toaster oven or in the oven until the center of the tart is warm. 

          Top tip

          ​Be sure to slice the sweet potatoes the same thickness. This will allow the potatoes to cook evenly. Potatoes should be about ¼ inch thick or thinner. 

          FAQ

          Why do you prick holes into the puff pastry before baking?

          Pricking holes throughout the puff pastry is known as docking. You dock the dough before baking so that steam escapes and the pastry is able to cook evenly. This will prevent bubbles from rising in the dough. 

          How can I serve this Roasted Sweet Potato and Mushroom Tart?

          Serve this Roasted Sweet Potato and Mushroom Tart as an appetizer or accompanying a salad as a light lunch or dinner. This tart can be served warm or at room temperature. 

          How can I keep the tart from becoming soggy?

          ​Spreading the layer of goat cheese prevents the crust from becoming soggy. Precooking the mushrooms also helps to keep the crust from becoming soggy because moisture is released from the mushrooms. If the mushrooms still appear wet after cooking, use a slotted spoon and transfer them to a paper towel to drain. 

          Can I make this tart ahead of time?

          This sweet potato tart is perfect to make ahead of time. Simply prepare the crust be piercing it with a fork and spreading the goat cheese on top. Prepare the sweet potatoes and caramelize the mushrooms. Store ingredients separately. When you are ready to enjoy, assemble the tart, wash with the egg mixture and bake.
