Why You’ll Love This Chicken Wellington

This recipe hits the sweet spot between elegance and comfort. It transforms simple ingredients into something visually dramatic and flavor-packed. The puff pastry turns golden and buttery, encasing the chicken and mushroom filling in a crisp shell that shatters at the touch of your fork. The chicken stays moist and flavorful thanks to a brief sear and flavorful spread of mustard. Even picky eaters will find themselves asking for seconds.

It’s also very make-ahead friendly. You can prep the components earlier in the day and just bake when you’re ready. This makes it perfect for stress-free entertaining.

What Kind of Puff Pastry Should I Use?

You want to go for all-butter puff pastry if you can find it. It gives a richer flavor and better flake than vegetable-oil-based varieties. Most frozen puff pastry sheets from the freezer section of your grocery store will work fine—just make sure they’re fully thawed before using, but still cold. This will help you avoid tearing or stretching the dough when wrapping the chicken.

Ingredients for the Chicken Wellington

Chicken Wellington is all about layers of flavor and texture, and each ingredient has a job to do. Choose high-quality basics and your final result will reflect that.

• Chicken breasts
• Puff pastry sheets
• Cremini mushrooms
• Shallot
• Garlic
• Fresh thyme
• Dijon mustard
• Prosciutto slices
• Egg yolk
• Olive oil
• Butter
• Salt and pepper

How To Make the Chicken Wellington

Step 1: Sear the Chicken

Start by seasoning the chicken breasts with salt and pepper. Heat a bit of olive oil in a skillet and sear the chicken for 2-3 minutes per side until golden brown. Remove from the pan and let them cool completely.

Step 2: Make the Mushroom Duxelles

In the same skillet, melt butter and add finely chopped mushrooms, shallots, and garlic. Cook until all the moisture evaporates and the mixture is rich and paste-like. Stir in fresh thyme, season with salt and pepper, and let it cool.

Step 3: Assemble the Layers

Lay out slices of prosciutto on plastic wrap, overlapping slightly. Spread the mushroom mixture on top. Place a chicken breast in the center, brush with Dijon mustard, and wrap it tightly with the prosciutto-mushroom layer. Chill in the fridge for 15 minutes to firm up.

Step 4: Wrap in Puff Pastry

Roll out the puff pastry into a square large enough to wrap around the chicken package. Place the chilled parcel in the center and wrap the pastry around it, sealing the edges with a little water. Trim any excess and place seam-side down on a baking sheet. Chill again for 10 minutes.

Step 5: Egg Wash and Bake

Brush the pastry with beaten egg yolk for a glossy finish. Optionally score the top lightly with a knife for decoration. Bake in a preheated oven at 400°F (200°C) for 25-30 minutes or until the pastry is deeply golden and puffed. Rest for 5 minutes before slicing.

How to Serve and Store Chicken Wellington

Chicken Wellington is best served hot and fresh from the oven when the pastry is still crisp. Each parcel slices beautifully, revealing the cross-section of flaky pastry, savory mushrooms, and juicy chicken.

This recipe feeds 4 people generously and can be doubled easily. If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F to keep the pastry crisp.
