Creating something visually striking and deeply flavorful doesn’t require complexity. This Mushroom Onion Tart with Microgreens is proof that a few good ingredients and a little inspiration can result in something completely unique. Our tart uses a golden, flaky crust made from scratch, filled with a creamy cheese base, topped with tender mushrooms and sweet caramelized onions, then finished with a scattering of fresh microgreens. The result is a rustic tart that brings comfort, color, and character to any table.
Why Choose Mushroom Onion Tart with Microgreens?
The combination of mushrooms, onions, and cheese is already a proven classic. But this version transforms those familiar elements into something original. The homemade tart crust has a tender bite but holds its shape perfectly. Inside, a rich filling made from a blend of soft cheeses and a spoonful of sour cream creates a luscious base. On top, sautéed mushrooms—preferably dried and rehydrated for extra depth—and deeply caramelized red onions bring warmth and umami. The microgreens finish the dish with freshness and brightness. This tart feels layered, but it remains clear in its identity.
Ingredients You’ll Need
For the crust, use 200 g all-purpose flour, 100 g cold butter cut into small cubes, a pinch of salt, and 3–4 tablespoons cold water. Mix the flour and salt, then rub in the butter until the texture resembles crumbs. Add water slowly, mixing until a dough forms. Chill before rolling out.
For the filling, prepare 150 g mixed soft cheeses—such as ricotta, goat cheese, or cream cheese—combined with 3 tablespoons sour cream and one egg. Add a touch of black pepper.
For the topping, use 200 g mushrooms (sliced fresh or soaked dried ones), 1 large red onion thinly sliced, 1 tablespoon olive oil, and salt. Finish with a generous handful of microgreens.
How to Prepare the Tart
Start with the crust. After mixing and chilling the dough, roll it out and fit it into a tart pan. Prick the base with a fork and pre-bake it at 180°C (350°F) for 10 minutes.
While it bakes, sauté the sliced red onion in olive oil over low heat until golden and sweet. Add a pinch of salt and let it cool. In the same pan, cook the mushrooms until they release moisture and begin to brown.
Next, mix the cheeses, sour cream, and egg in a bowl. Spread this filling over the slightly baked tart shell. Then layer the caramelized onions and sautéed mushrooms on top. Return the tart to the oven and bake for 20–25 minutes or until the edges are golden and the center is set. Remove from the oven and let it rest. Before serving, add fresh microgreens across the surface.
Serving Suggestions to Try
This tart works well in slices or as a whole dish at gatherings. It tastes best slightly warm or at room temperature. Pair it with simple side salads, crusty bread, or seasonal roasted vegetables. If serving at brunch or lunch, offer it with fresh fruit or cucumber ribbons. You can also cut it into small wedges or squares for buffet-style events or picnics. The tart’s richness pairs well with lighter bites, balancing textures and flavors.
What Makes Mushroom Onion Tart with Microgreens Special?
Our crust has its own charm—light but buttery, crisp at the edges but soft inside. The cheese filling is smooth and creamy without overpowering the toppings. The mushrooms give earthiness and the onions add subtle sweetness, while the microgreens keep everything lifted and balanced. The dish isn’t about quantity—it’s about harmony. Each part brings something different, and together, they create something satisfying and memorable. Even the look of this tart, with its clean slices and vibrant greens, feels crafted yet relaxed.
Variations and Creative Twists
You can make the tart your own with a few smart adjustments. Try switching the cheese blend—blue cheese or grated aged cheese will add sharpness. For a more savory kick, mix in roasted garlic or spread a thin layer of mustard on the crust before adding the filling. You can use leeks instead of onions or include a few sun-dried tomatoes. The mushrooms can be wild varieties, mixed for deeper flavor. And for a different texture, top with crushed toasted walnuts or pumpkin seeds. All these additions can elevate the tart while keeping the soul of the dish intact.
