Your New Veggie Star of the Show

We all know that eating more plant-based meals is better for our planet, bodies, moods, and minds. When such plant-based mains are enveloped in pillowy puff pastry and baked to golden goodness, a magical main dish is created! This one is a show stopper. I made it on Thanksgiving and have been making it on repeat ever since. The reviews (from even the most non-veg friends and family in my life) have all been 5 stars! Portobello, mixed mushrooms, caramelized onions, lots of great herbs, and seasoning will leave you satisfied, happy, and not at all missing the meat. Let’s face it, I can recommend tucking shredded cardboard into puff pastry and we would likely all love it. I was inspired to create a simpler version of the Veg Wellington by Alexa Weibel in the NYT. I love it. I know you will too.
Ingredients
Mushrooms:

- 4-5 large portobello mushrooms
- Approx 2 lbs of mixed mushrooms (I like shiitake, oyster, or whatever you can find at the grocery store or market)
- Kosher salt
- Black pepper
- Extra-virgin olive oil (13 tbsp)
- 4 shallots, chopped
- 6 garlic cloves, finely chopped
- 2-3 Tbsp fresh rosemary, chopped (rough approximate) , couple of sprigs of rosemary for plating
- 1-2 Tbsp fresh thyme leaves (rough approximate)
- Balsamic vinegar, 1 Tbsp
- Low sodium soy sauce, 2 Tbsp
- 1 cup toasted and finely chopped walnuts (optional – I have made it without for a friend with allergies and it is still just as good)
Onions:
- 3 Tbsp butter (can use vegan butter)
- 2 yellow onions, 1/4 inch slices
- 3/4 tsp light brown sugar
- 11/4 tsp kosher salt (I use Diamond Crystal)
- 1 tsp black pepper
- 3/4 cup water
- 1 tbsp balsamic vinegar
Putting it all together:
- All-purpose flour (for dusting only)
- 1 14 oz package of frozen puff pastry (thaw per package instructions)
- 1 egg, beaten
Steps
Portobello Mushroom Prep:
- Clean the portobello mushrooms with a damp paper towel
- Remove stems and cut off excess curled rims to make the mushroom sit flat (keep the stems and scraps- you will use them in the steps below)
- Brush the portobello caps with 3 tbsp olive oil on both sides
- Season with salt and pepper on both sides
- Heat 2 tbsp olive oil in a large skillet
- Cook the portobellos approx 5 minutes per side
- Transfer the cooked mushrooms to a wire rack to let them cool and drain (they can get watery)
Mixed Mushroom Filling Prep:
- Roughly chop the 2 lbs of mixed mushrooms and reserve portobello stems and rims (from step 2 above)
- Heat 4 tbsp olive oil on medium-high in the already used large skillet
- Add half of this chopped mushroom mixture to the pan
- Add half of the shallots, garlic, rosemary, thyme leaves, salt, and pepper
- Cook for about 10 minutes, stirring on occasion
- Transfer to a bowl
- Repeat with the second half of the chopped mushrooms, shallots, garlic, rosemary, thyme leaves, salt and pepper (cook for a bout 10 minutes
- Add the first batch of cooked mushrooms and aromatics to this newly cooked second batch in the skillet
- Add soy sauce and 1 tbsp balsamic vinegar, cook for another 5 minutes
- Transfer the mushroom mixture to a bowl, add in the finely chopped and toasted walnuts (optional)
- Let the bowl cool, you can drain some of the liquid after about 20-30 minutes or so

Onion Prep:
- melt the butter (or vegan butter) over medium heat in the same skillet used above (let’s minimize clean up!)
- Add the sliced onions, sugar, salt, and pepper and cook for about 5 minutes. Stir on occasion.
- Add in 3/4 cup water and stir on occasion. The onions will caramelize and the liquid will evaporate (approx 15-20 min)
- Add in the tbsp of balsamic vinegar


Assembly
- Heat oven to 400 fahrenheit
- Dust some flour on a large parchment paper sheet on your work surface
- Unfold the puff pastry (thawed according to the package directions) on the parchment paper
- Using a floured rolling pin, roll out the puff pastry into a 13×16 inch rectangle
- Place the parchment paper on a large sheet pan
- The 16 inch side should be closest to you
- Take half of the mushroom mixture and arrange it in a 4 x 10 inch strip in the center of the puff pastry – leave 1-2 inches on each end
- Next, place the caramelized onions on top pour the first half of mushroom mixture
- Lay the portobello mushrooms on top of the onions, they may overlap slightly which is fine
- The remaining mushroom mixture is placed on top of the portobello mushrooms
- Lift one side of the puff pastry over the filling to cover at least 1/2 of it
- Brush the puff pastry covering the mushrooms with the beaten egg, then lift the other side of the puff pastry and place it over the egg washed side
- Gently press down to seal the puff pastry top layer on to the first layer
- Brush the ends of the puff pastry with the egg and press them to seal and tuck underneath
- Brush the whole puff pastry with the remaining beaten egg.
- Feel free to decorate the puff pastry with any pattern on your liking (don’t apply too much pressure as you will slice through the puff pastry)
- Bake for about 45-50 minutes until golden and flaky
- Let it cool on the baking sheet, draining any excess moisture that may appear on the sheet pan
- Plate the mushroom Wellington on a board with sprigs of rosemary around it or on it!
- As always, totally enjoy this one!
