This vegan savory tart features a creamy filling of sautéed mushrooms infused with garlic, rosemary, and black pepper. It's rustic, super simple to prepare, and requires common ingredients.
Drain the soaked cashews and add them to a blender. Add the water, nutritional yeast, white vinegar, and salt.
Blend on high speed for 15-30 seconds or until smooth. You will end up with a liquid cream. Transfer to a small bowl and set aside.
Mushroom Filling
Heat the butter in a non-stick skillet over medium heat. Once hot, add garlic and sauté for 1 minute.
Next, add the sliced mushrooms and sauté for 3-5 minutes or until cooked. Season with soy sauce, dried rosemary, and ground black pepper. Cook for one more minute.
Turn off the heat and add the cashew cream to the sautéed mushrooms. Stir to combine. Set aside.
Assemble: Lightly grease a 7.5-inch tart pan with oil or butter. Unroll your pie crust (or flatten it, if homemade), and press it into the tart pan. Trim off any excess dough using a pair of scissors or by running a rolling pin over the tart pan. Poke the bottom and sides of the crust with a fork.
Transfer the mushroom filling to the pie crust and spread it evenly.
Bake for 35-40 minutes or until the crust is golden brown. If using a transparent glass tart pan, you can take a look at the bottom of the pan to check if the crust is cooked.
Let cool for a few minutes before serving! You can serve it as is or with a green salad on the side.
This mushroom tart will keep for up to 4 days in the refrigerator.
Notes
Double the recipe. While I used a 7.5-inch tart pan, feel free to double the filling to make a 9-inch tart. The filling will be slightly thicker, making the tart heartier!
Use pie crust. I highly recommend going with a pie crust instead of puff pastry. The latter would become soggy due to the creamy filling.
Season with your favorite herbs. You can easily switch up the herbs to your liking. Add cilantro, oregano, spring onions, or even thyme for an herby tart!
Mix different types of mushrooms. Vary the varieties of mushrooms for a combination of flavor and texture!
Make mini tarts. If you plan on serving this as an appetizer, bake it into individual mini tarts instead of a larger one.
Top with vegan cheese! You can sprinkle grated vegan cheese on top of the filling before baking to take this tart to the next level!
If serving to guests: garnish this tart with some arugula just before serving for a fancy-looking main.
