🛠️ Instructions
I. Prepare the Filling
- Sauté Aromatics: Heat oil in a large skillet over medium heat. Add the chopped onion and sauté until soft (about $5 \text{ minutes}$). Add the minced garlic and cook for $1 \text{ minute}$.
- Cook Mushrooms: Add the finely chopped mushrooms. Cook over medium-high heat for $10 \text{ to } 15 \text{ minutes}$, stirring occasionally. It is crucial to cook until all the liquid has evaporated.
- Add Flavor: Stir in the tomato paste, soy sauce (or Tamari), fresh herbs, salt, and pepper. Cook for $2 \text{ minutes}$.
- Mix Loaf Base: In a large bowl, combine the mushroom mixture, cooked lentils, chopped nuts, nutritional yeast, and Panko breadcrumbs.
- Test Consistency: Mix well. The mixture should be firm enough to hold its shape (if it’s too wet, add another tablespoon of breadcrumbs). Taste and adjust seasoning.
- Chill: Form the mixture into a compact log shape (about $8 \text{ inches}$ long and $3 \text{ inches}$ wide). Wrap in plastic wrap and chill for at least $30 \text{ minutes}$—this is vital for easy wrapping.
II. Assemble the Wellington
- Preheat & Prep: Preheat oven to $400^\circ\text{F}$ ($200^\circ\text{C}$). Line a baking sheet with parchment paper.
- Roll Pastry: Unroll the first sheet of puff pastry. Place the chilled loaf slightly off-center on the pastry.
- Wrap: Bring the pastry up and over the loaf, folding it to encase the filling entirely. Cut off any large excess pastry and pinch the seams tightly to seal.
- Flourish: If you have two sheets, use the second sheet to cut decorative strips or leaf shapes to lay on top.
- Transfer: Carefully place the wrapped Wellington seam-side down on the prepared baking sheet.
III. Bake
- Glaze and Score: Mix the plant milk and maple syrup for the vegan “egg wash.”3 Brush the entire pastry surface generously. Use a sharp knife to score shallow, diagonal lines across the top (do not cut through to the filling) and pierce a few small steam vents.
- Bake: Bake for $30 \text{ to } 35 \text{ minutes}$, or until the pastry is puffed, deeply golden brown, and cooked through.
- Rest: Let the Wellington rest for 4$10 \text{ minutes}$ before slicing into thick pieces.5
