This vegan version of the classic British sausage roll uses Beyond Beef, or your choice of meatless ground, mixed with fried onions, garlic, and thyme, wrapped in flaky puff pastry. This comforting vegan pastry is perfect as a Holiday appetizer!
Allow the puff pastry to thaw on the counter for 30-60 minutes.
Preheat the oven to 400°F/200°C and line a baking sheet with parchment paper.
Heat a drizzle of olive oil in a frying pan over medium heat. Add the onions and 1/4 teaspoon of salt, and cook for 6-7 minutes, until the edges are browned and crispy. Add the garlic and cook until fragrant, about 15 seconds. Set aside.
Unroll the puff pastry on a floured surface. If there are any tears in the pastry, seal them by pinching the pastry together. Cut the pastry in half lengthwise, and again horizontally by pressing down, not slicing, with a knife or bench scraper. You should have 4 even rectangles.
Combine the meatless ground with the onion mixture, breadcrumbs, thyme, pepper, and 1/2 teaspoon salt. Divide the mixture into 4 portions, and form each portion into a round log, the length of the pastry rectangles.
Place the vegan sausage rolls onto the center of the pastry and gently but tightly fold the sides over the sausage roll. Pinch to seal the seams.
Place the sausage rolls seam-side down on the lined baking sheet and brush with plant milk. Bake for 40-45 minutes, until golden brown and flaky. Slice each roll into 4 pieces and serve with Dijon mustard.
