Step-by-Step: How to Make Vegetarian Beef Wellington

Before You Start

Thaw your puff pastry in the fridge overnight.
Preheat oven to 400°F (200°C).

Let’s Cook!

1. Cook the Rice

Simmer brown rice in vegetable broth with thyme, rosemary, and sage until tender. Fluff with a fork and set aside.

2. Roast the Veggies

Toss diced butternut squash with olive oil, spread on a baking sheet. Do the same for diced mushrooms. Roast both until just tender, about 20 minutes.

3. Sauté the Onion & Garlic

In a large skillet, heat olive oil and cook onion until soft. Add garlic, then carefully pour in the whiskey (or juice). Simmer until the liquid is mostly gone.

4. Mix the Filling

To the skillet, add roasted squash, mushrooms, cooked rice, and chopped pecans. Toss to combine. Season generously with salt and pepper. Sprinkle flour over the mixture and stir to combine (this helps the filling hold together).

5. Shape and Wrap

Roll out your puff pastry on a floured surface into a 12-inch square. Place on a parchment-lined baking sheet. Pile the filling in a log shape down the center of the pastry. You can braid the pastry over the top or simply fold and seal the edges to form a log.

Pro Tips for Vegetarian Wellington Success

Don’t Overfill: Leave a border so you can easily seal the pastry.
Chill Before Baking: If possible, chill the assembled Wellington for 20–30 minutes so it holds its shape better.
Brush Well: Generously brush with butter or milk for the crispiest, most beautiful finish.
Let Rest: Slice after resting a few minutes so the filling doesn’t spill out.

What to Serve with Vegetarian Beef Wellington

Vegan Gravy or Red Wine Sauce: Adds even more flavor.
Cranberry Sauce: Bright and festive.
Roasted Vegetables: Carrots, Brussels sprouts, or parsnips.
Creamy Mashed Potatoes: For ultimate holiday comfort.

How to Store & Reheat

Fridge: Store leftovers in an airtight container for up to 3 days.
Freezer: Freeze slices or the whole baked Wellington for up to 3 months. Thaw in the fridge before reheating.
Reheat: Warm slices in the oven at 350°F until heated through and the pastry crisps back up.

FAQ

Can I make this ahead?

Yes! Prepare the filling 1–2 days in advance. Assemble and bake the Wellington the day of for the best texture.

Can I freeze the filling or the whole Wellington?

Absolutely. The filling freezes well. The baked Wellington can also be frozen—just reheat in the oven until hot and crisp.

I can’t find vegan puff pastry. What else can I use?

Try phyllo dough (layered with a little oil or butter), or make your own vegan pastry.

Can I add more protein?

Mix in cooked lentils or chickpeas to the filling for a protein boost.
