Vegan Holiday Roast Recipe

Thanksgiving and Christmas dinners are coming up and it’s time to start thinking about what to serve that will keep everyone happy. It’s got to be savory, satisfying, and pair well with a wide variety of side dishes. This Roasted Vegetable Wellington checks all the boxes.

I’ve served my Vegan Thanksgiving Wellington every year for the last seven years. However, this year I’m considering mixing things up and going with this vegetable roast. Maybe I’ll do one of each…decisions.

As you will see, this veggie roast does require some advance prep work. The Mushroom Pate (aka the secret ingredient) will need to be made at least a few hours ahead of time; ideally, a day in advance so the earthy flavors have time to develop.

Ingredients for Roasted Vegetable Wellington

1 pound cauliflower florets, cut into small bite-size pieces
3/4 pound carrots, peeled and trimmed to 1/2″ diameter
1/4 pound asparagus, trimmed
2 tablespoons olive oil
1 tablespoon water
9 ounces fresh spinach leaves
1 sheet puff pastry dough, thawed
2 cups Mushroom Pate
1 tablespoon butter, melted

How to Make Roasted Vegetable Wellington

STEP ONE: Prep the Vegetables. Place cauliflower, carrots, and asparagus into a large bowl. Drizzle with olive oil, season with salt and pepper, and toss to coat. Arrange in a single layer on a foil-lined baking sheet, separating the asparagus from the cauliflower and carrots.

STEP TWO: Roast the Vegetables. Roast for 15 minutes, until asparagus is tender. Remove the asparagus and set aside. Return the baking pan to the oven for an additional 5 minutes, until the cauliflower and carrots are tender. Set aside.

STEP THREE: Cook the Spinach. While the cauliflower, carrots, and asparagus are roasting, add spinach and 1 tablespoon of water to a large skillet over medium-high heat. Cook, stirring frequently until spinach is wilted. Transfer the spinach to a colander, rinse with cold water, and squeeze out as much liquid as possible. Spread out on a kitchen towel to dry.

STEP FOUR: Lower the Heat. Reduce the oven temperature to 375°F.

STEP FIVE: Prep Pastry Dough. On a lightly floured surface, roll out the pastry dough to at least 12″x16″. Spread evenly with Mushroom Pate, leaving a 1-inch border all around.

STEP SIX: Add Roasted Vegetables. Arrange the carrots and asparagus lengthwise to cover the pate. Top with cauliflower and spinach.

STEP SEVEN: Roll and Shape. Carefully roll into a log shape so that the vegetables are completely covered by the puff pastry dough. Pinch the ends closed and tuck under. Lightly brush melted butter over the surface.

STEP EIGHT: Bake. Transfer to a parchment-lined baking sheet. Bake for 40-45 minutes, until golden in color. Allow to stand for 15 minutes. Cut into individual servings and serve.
