Ingredients


To create the perfect Wild Mushroom and Caramelized Onion Tart, gather the following ingredients:
– 1 pre-made pie crust (store-bought or homemade)
– 1 pound wild mushrooms (such as chanterelles, shiitake, or oyster), cleaned and sliced
– 2 medium onions, thinly sliced
– 3 tablespoons unsalted butter
– 2 tablespoons olive oil
– 2 cloves garlic, minced
– 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
– ½ cup heavy cream
– 2 large eggs
– ½ cup grated Gruyère cheese (or your preferred cheese)
– Salt and pepper to taste
– Fresh parsley for garnish (optional)

Step-by-Step Instructions


Follow these steps to create your delectable Wild Mushroom and Caramelized Onion Tart:
1. Preheat the Oven: Start by preheating your oven to 375°F (190°C). This ensures your tart bakes evenly.
2. Prepare the Crust: Roll out your pie crust into a tart pan and press it against the sides. Prick the bottom with a fork to prevent bubbling and set it aside.
3. Caramelize the Onions: In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onions and sprinkle with salt. Cook for about 15-20 minutes, stirring frequently, until the onions turn golden brown and soft.
4. Sauté the Mushrooms: In the same skillet, add another tablespoon of butter and the sliced wild mushrooms. Cook for 5-7 minutes until softened and browned. Add the minced garlic and thyme, cooking for 1 additional minute until fragrant.
5. Combine: In a mixing bowl, whisk together the heavy cream, eggs, salt, and pepper. Stir in the sautéed mushrooms and caramelized onions until well combined.
6. Fill the Crust: Pour the mushroom and onion mixture into the prepared crust, spreading it evenly. Sprinkle the grated Gruyère cheese on top.
7. Bake: Place the tart in the preheated oven and bake for 30-35 minutes, or until the filling is set and the top is golden brown.
8. Cool: Remove the tart from the oven and let it cool for 15-20 minutes before slicing. This helps the filling set further.
9. Garnish: Before serving, sprinkle with fresh parsley if desired.
Following these steps will guide you effortlessly in crafting this incredible Wild Mushroom and Caramelized Onion Tart that bursts with flavor.

2. Accompaniments: Pair the tart with a fresh salad, such as arugula or mixed greens, lightly dressed to complement the richness of the tart.
3. Slice Size: When cutting the tart, aim for slender slices that make it easy to handle and delightful to eat.
4. Beverage Pairing: This tart pairs wonderfully with white wine, especially Chardonnay or Sauvignon Blanc, enhancing its flavors.

Additional Tips


– Use Fresh Herbs: Fresh thyme really enhances the flavor of the mushrooms and onions. Don’t skip this ingredient; it adds aromatic depth.
– Experiment with Cheese: While Gruyère is delicious, feel free to try feta or goat cheese for a tangy twist.
– Let It Rest: Allow the tart to cool for at least 15 minutes before slicing. This helps the filling set for cleaner cuts.
– Serve Warm: This tart is best enjoyed warm, as the flavors are most pronounced when served fresh from the oven.

Recipe Variation


Change up the tart to suit your taste or dietary needs! Here are some fun ideas:
1. Mixed Mushroom Medley: Use a variety of mushrooms like button, portobello, or cremini for different textures and flavors.
2. Vegan Option: Replace heavy cream with coconut milk and use a flaxseed egg in place of traditional eggs.
3. Additional Vegetables: Add spinach or kale for extra color and nutrients. Just sauté them with the mushrooms for a few minutes.
4. Spicy Kick: Incorporate red pepper flakes or sauté jalapeños for a zesty flavor boost.

Freezing and Storage


Storage: Keep leftovers in an airtight container in the refrigerator. The tart will stay fresh for about 3-4 days.
Freezing: You can freeze the unbaked tart or cooked leftovers. Wrap firmly in plastic wrap, then foil. It will last in the freezer for up to 3 months.
Reheating: To reheat, bake from frozen at 350°F (177°C) for about 30-40 minutes. Thaw the tart overnight in the fridge before reheating for best results.
