Beef Wellington Mushroom Paste

The first time I made Beef Wellington, I was terrified. A special anniversary dinner, and here I was attempting one of the most elegant dishes in the world. But as I wrapped that perfectly seared beef in mushroom duxelles and pastry, watching it transform into something truly restaurant-worthy, I understood why this dish has earned its place at the finest tables. Now, whenever someone needs to impress, this is the recipe I reach for.

I remember the moment I pulled that Wellington from the oven and the aroma hit me, golden pastry crackling slightly as I let it rest. My partner came into the kitchen, stopped dead, and said, "You made that?" That's the magic of this dish, it surprises you every time.

Ingredients

• 1.2 kg center-cut beef tenderloin: Use the best quality beef you can afford, as this is the star. I trim it myself to ensure even thickness, which guarantees even cooking
• Salt and freshly ground black pepper: Don't skip the fresh grinding, it makes a real difference in the searing stage
• 2 tbsp olive oil: For searing, this is about getting that beautiful crust, so use an oil with a high smoke point
• 500 g cremini or button mushrooms, finely chopped: I've learned to chop them small and let them cook down properly, moisture evaporation is everything here
• 2 shallots, finely diced: Shallots give a sweetness that pure onions won't, it's worth the extra knife work
• 2 cloves garlic, minced: Fresh garlic only, never the jarred stuff for this one
• 2 tbsp unsalted butter: The foundation of your duxelles, it should smell incredible when the mushrooms hit the pan
• 2 tsp fresh thyme leaves: Fresh herbs truly matter here, dried just doesn't have the same brightness
• 12 thin slices prosciutto: This wraps your beef and adds a salty note that balances the richness beautifully
• 500 g puff pastry: Quality matters, all-butter pastry will give you a better result than margarine-based versions
• 1 egg yolk and 1 tbsp milk: This creates the glossy golden finish that makes it look like it came from a bakery
• 1 tbsp Dijon mustard (optional): A thin layer under the duxelles adds sophistication you'll taste in every bite

Instructions

Get Everything Ready:

Pat your beef completely dry with paper towels, this is crucial for getting that beautiful sear. Season it generously, and I mean generously, all over with salt and pepper. Let it sit for a few minutes while you heat your skillet, this helps the seasoning stick. The pan should be hot enough that a drop of water sizzles immediately.

Sear the Beef to Golden Perfection:

Add olive oil to your skillet and let it heat until it shimmers. Place the beef in carefully and listen for that satisfying sizzle. Don't move it around, just let each side develop that gorgeous brown crust, about 2 to 3 minutes per side. You're building flavor here, that fond on the pan is liquid gold. Once all sides are browned, transfer to a plate and let it cool completely, this takes patience but it's essential.

The Part Where Magic Happens:

In your skillet, melt butter over medium heat and watch it foam. Add your finely diced shallots and minced garlic, letting them soften and become fragrant, about 2 minutes. Now add your chopped mushrooms, and here's where it gets interesting. At first they'll release water, don't panic, just keep stirring. You're waiting for that moisture to evaporate completely, 10 to 15 minutes of patient stirring. The mixture should go from wet and loose to dense and paste-like, the smell will tell you when you're there, earthy and concentrated. Taste it, season with salt and pepper. Spread it on a plate to cool, this is your duxelles.

Building the Foundation:

Lay out a large piece of plastic wrap and arrange your prosciutto slices in a slightly overlapping pattern, like shingles on a roof. They should form a rectangle big enough to completely wrap around your beef. Spread your cooled mushroom duxelles evenly over the prosciutto layer, leaving just a tiny bit of prosciutto showing at the edges.

The Wrap:

Place your cooled beef tenderloin on top of the mushrooms, positioning it toward one end. Using the plastic wrap as your guide, roll the prosciutto and mushrooms tightly around the beef, creating a sealed log. The plastic wrap keeps it together and makes this whole step easier. Twist the ends tight and refrigerate for at least 30 minutes. This time in the cold firms everything up beautifully.

Pastry Perfection:

Flour your work surface lightly and roll out your puff pastry into a rectangle large enough to encase your beef completely. The pastry should be thin enough to be elegant but thick enough to protect the beef inside. Remove your beef from the plastic wrap and place it in the center of the pastry. Beat together your egg yolk and milk to make an egg wash, brush it along the edges of the pastry. Fold the pastry up and around the beef, creating a tight package, trim any excess and pinch all the seams to seal them properly. Place it seam-side down on a parchment-lined baking sheet, this keeps the seam from opening during baking. Brush the top and sides with more egg wash, and if you're feeling fancy, decorate with pastry scraps cut into leaves or other shapes.

The Final Rest and Bake:

Let your Wellington chill for 15 minutes while you preheat your oven to 220°C. This chill helps the pastry set and prevents shrinking. Bake for 40 to 45 minutes, watching until the pastry is a deep golden brown. The real test is the internal temperature, aim for 50°C at the center for that perfect medium-rare, a meat thermometer is your best friend here. When it's done, remove it from the oven and let it rest for a full 10 minutes before slicing. This rest is sacred, it keeps all the juices inside instead of spilling onto your plate.

I served this at my sister's wedding rehearsal dinner, and watching everyone's faces as they cut into it and saw that perfect pink center surrounded by earthy mushrooms and crispy pastry, I realized this dish transcends just being dinner, it becomes the story of the meal.

Keeping It Fresh

You can assemble the Wellington up to 24 hours ahead and refrigerate it, covered, before baking. This actually works in your favor because the pastry dries out slightly, which helps it get even crispier in the oven. If you're making it further in advance, you can freeze the assembled Wellington for up to a month, just add a few extra minutes to the baking time if cooking from frozen.

When You're Missing Something

If you can't find good prosciutto, thin slices of pâté work beautifully and add richness. For the puff pastry, I've used homemade when I'm feeling ambitious, but honestly, quality store-bought works perfectly. If cremini mushrooms aren't available, use a mix of whatever mushrooms you can find, wild mushrooms actually make this even better. Missing fresh thyme? Use half the amount of dried thyme, it's more concentrated.

Serving Ideas That Clicked

This is the kind of dish that deserves a proper presentation. Slice it at the table if you're feeling theatrical, serve each slice on warmed plates. A rich red wine sauce or Madeira jus on the side lets people customize their plate. I always serve it with simple sides that don't compete, maybe roasted asparagus or a delicate potato gratin. The pastry crust is already rich and golden, so let it be the star. A bold red wine like Bordeaux or Cabernet Sauvignon is perfect alongside it, the tannins cut through the richness beautifully.

• Remember to let it rest after coming out of the oven, this keeps the beef from releasing all its juices immediately
• Slice it confidently with a sharp knife, sawing motions create messy edges, one smooth cut per slice
• If you made extra mushroom duxelles, you can serve a small dollop on the side as an extra flavor boost
