Ingredients

• 1 1/2 cups mixed mushrooms (such as cremini, shiitake, and button), sliced
• 1 cup brown or green lentils, rinsed and drained
• 1/2 cup chopped walnuts
• 2 tablespoons olive oil
• 1 onion, chopped
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 cup vegetable broth
• 1 tablespoon tomato paste
• 1 sheet puff pastry, thawed
• 1 egg, beaten (for egg wash)
• Fresh parsley or thyme, chopped (for garnish)

Instructions

1. Step 1: Preheat your oven to 400°F (200°C). Roll out the puff pastry on a lightly floured surface to a thickness of about 1/8 inch. Transfer the pastry to a 9-inch tart pan with a removable bottom. Trim! the edges and press the pastry into the corners of the pan.
2. Step 2: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Add the sliced mushrooms and cook until they release their moisture and start to brown, about 5 minutes. Add the minced garlic and cook for 1 minute.
3. Step 3: Stir in the lentils, thyme, salt, and pepper. Cook for 1 minute. Add the vegetable broth and tomato paste. Bring to a boil, then reduce the heat to low, cover, and simmer until the lentils are tender, about 20-25 minutes. Stir in the chopped walnuts.
4. Step 4: Spread the lentil and mushroom mixture into the pastry-lined tart pan. Brush the edges of the pastry with the beaten egg for a golden glaze. Bake the tart for 25-30 minutes, or until the pastry is golden brown and the filling is heated through.

Handy Tips

• For an extra flaky crust, keep the puff pastry cold and handle it gently. If it warms up and becomes too soft, refrigerate it for about 10 minutes to firm it up before proceeding.
• Don’t overfill the tart shell, as the filling will set a bit as it cools. Leave about 1/2 inch of space between the filling and the top of the pastry.
• Consider using different types of mushrooms or nuts to change up the flavor and texture of the tart. For example, pecans or hazelnuts could add a nice depth, while shiitake or oyster mushrooms could enhance the umami flavor.

Heat Control

When baking the tart, it’s essential to maintain the right temperature to ensure the pastry cooks evenly and the filling heats through without drying out. Keep an eye on the tart after 20 minutes, as the pastry can quickly go from perfectly golden to overly browned. The ideal internal temperature for the filling should be at least 165°F (74°C) to ensure food safety.

Crunch Factor

The crunch in this dish comes from the walnuts and the flaky pastry crust. To enhance the crunch, ensure the walnuts are toasted lightly before adding them to the filling. For the pastry, baking it until it’s golden brown will provide the perfect textural contrast to the soft, savory filling.

Pro Kitchen Tricks

• To prevent the pastry from becoming too brown, cover the edges with foil or a pie shield for the last 10-15 minutes of baking.
• For a glossy finish, brush the tart with a little bit of olive oil or egg wash after it’s baked.
• Let the tart rest for a few minutes before serving. This allows the filling to set and makes it easier to slice and serve.

Storage Tips

• The tart can be made ahead and refrigerated for up to a day before baking. Let it come to room temperature before baking.
• Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the oven at 350°F (180°C) until warmed through.
• Consider freezing the tart before baking for up to 2 months. Thaw overnight in the refrigerator and bake as directed.

Gift Packaging Ideas

If you’re considering gifting this tart, a beautifully presented package can make all the difference. Wrap the cooled tart in plastic wrap or aluminum foil and place it in a decorative tin or box. Add a ribbon or a gift tag with baking instructions for a personal touch. Alternatively, package slices of the tart in individual portions, perfect for a gourmet gift basket or a unique office treat.

Flavor Variations

• Spice it up with a pinch of red pepper flakes or a sprinkle of smoked paprika for added depth.
• Top the tart with caramelized onions or roasted garlic for an intense flavor boost.
• Swap the lentils for chickpeas or black beans for a different texture and nutritional profile.

Troubleshooting

• If the pastry becomes too brown, it may be due to overbaking. Check the tart frequently during the baking time, and cover the edges if necessary.
• For a filling that’s too dry, add a little more vegetable broth or tomato paste. If it’s too wet, bake the tart for a few more minutes to reduce the moisture.
• Texture problems with the lentils can be solved by adjusting the cooking time. If they’re too hard, cook for a few more minutes. If they’re too soft, reduce the cooking time slightly.

FAQs

• Can I freeze it? Yes, the tart can be frozen before baking for up to 2 months. Thaw overnight in the refrigerator and bake as directed.
• Is it gluten-free? The filling is gluten-free, but the puff pastry contains gluten. Consider using a gluten-free pastry option for a gluten-free version.
• Can I double the recipe? Yes, the recipe can be doubled. Simply multiply all the ingredients by two and adjust the baking time as needed.
