1 pound carrots, trimmed and peeled
1 tablespoon avocado oil
1 tablespoon maple syrup
salt
freshly ground black pepper
3/4 cup walnut halves and pieces
1 tablespoon olive oil
1 white or yellow onion, diced
2 medium carrots, trimmed, peeled, and diced
2 medium stalks celery, trimmed and diced
3 cloves garlic, minced
3/4 cup French lentils
1 bay leaf
2 teaspoons fresh thyme leaves
2 teaspoons chopped fresh rosemary leaves
2 1/4 cups vegan chicken-style or vegetable broth
1 sheet vegan puff pastry (or two smaller sheets), thawed
3 tablespoons aquafaba

Directions

Start by preheating your oven to 400°F (200°C). Toast the walnuts briefly, then set them aside to cool. Roast the whole carrots wrapped in foil until tender, then uncover, drizzle with avocado oil and maple syrup, season, and roast again until lightly caramelized.

In a large pan, heat olive oil and sauté onion, diced carrots, and celery until softened. Add garlic, lentils, herbs, bay leaf, and broth. Simmer covered until lentils are tender and liquid is absorbed.

Chill the roasted carrots and lentil mixture for several hours or overnight. Pulse the walnuts in a food processor, then add the lentil mixture and pulse to form a crumbly but cohesive filling.

Roll out the puff pastry and layer half the lentil mixture, followed by the roasted carrots, then the remaining lentils. Carefully roll and seal the pastry around the filling, brushing edges with aquafaba. Seal ends, brush the entire surface, and score the top.

Bake at 400°F (200°C) for 40–45 minutes until golden brown and puffed. Let rest before slicing and serving.

Variations

You can swap walnuts for pecans or mushrooms for a different flavor profile. Add spinach or kale to the lentil mixture for extra greens. For a spiced twist, incorporate cumin or smoked paprika. You can also make individual mini Wellingtons instead of one large centerpiece.

Storage/Reheating

Store leftover slices in an airtight container in the refrigerator for up to five days. For longer storage, freeze slices for up to six weeks. Reheat in the oven at 350°F (175°C) until warmed through to maintain crisp pastry. Avoid microwaving if possible, as it softens the crust.
