Roasted Vegetable Wellington

Last updated on December 4th, 2025

A vegetable Wellington transforms humble produce into an elegant centerpiece that rivals any traditional meat-based Wellington. It’s super easy but looks totally impressive! The veggies get all tender and flavorful while cooking, and the mushrooms add an amazing savory taste. You can make this for a casual dinner or when friends come over – either way, everyone’s going to love digging into those layers of pastry and vegetables.

Recipe

Ingredients:

• 2 sheets puff pastry, thawed
• 1 medium butternut squash, peeled and cut into 1-inch cubes
• 2 red bell peppers, sliced
• 1 pound mushrooms, finely chopped
• 3 cloves garlic, minced
• 2 shallots, finely diced
• 2 tablespoons fresh thyme
• 2 tablespoons olive oil
• Salt and pepper to taste
• Plant milk or egg wash for brushing
• Optional: fresh spinach, roasted carrots, or other seasonal vegetables

Steps:

1. Preheat oven to 400°F (200°C). Toss butternut squash and peppers with olive oil, salt, and pepper. Spread on a baking sheet and roast for 25-30 minutes until tender but still holding shape. Let cool completely.
2. Make the mushroom duxelles: In a large pan, sauté mushrooms, garlic, and shallots until the moisture evaporates (about 15-20 minutes). Add thyme, season well, and cook until the mixture is dry and resembles a paste. Cool completely.
3. Roll out one puff pastry sheet on a floured surface. Spread mushroom duxelles in the center, leaving a 2-inch border.
4. Layer roasted vegetables on top of duxelles, arranging them tightly together.
5. Brush pastry edges with water. Place the second pastry sheet on top, pressing the edges to seal. Trim excess and crimp edges decoratively.
6. Score top in a diamond pattern, being careful not to cut through completely. Brush with plant milk or egg wash.
7. Bake for 35-40 minutes until deeply golden brown. Rest for 10 minutes before slicing.

Tips and Tricks

• Pat roasted vegetables dry with paper towels before assembly to prevent moisture from making the pastry soggy
• Keep puff pastry cold until ready to use for the best results
• Make components ahead and assemble day-of for easier preparation
• Use a sharp knife for clean scoring to create attractive patterns
• Create small steam vents on top of the pastry to prevent splitting
• If the edges brown too quickly while baking, cover them with foil

How to Serve: Serve your Wellington while warm but not hot, as this allows the layers to set properly for clean slicing. Present it whole at the table for maximum impact before cutting. Each slice should be accompanied by a rich mushroom gravy or vegetable sauce. Consider serving with roasted root vegetables, steamed green beans, or a fresh salad to complement the dish. This Wellington pairs beautifully with both red and white wines, particularly a medium-bodied Pinot Noir or crisp Chardonnay.
