Chicken Wellington

This is the kind of recipe that makes you feel like you’re running a fancy restaurant from your kitchen, complete with the smug satisfaction of knowing you just wrapped chicken in buttery pastry and called it gourmet.

This recipe serves up restaurant-quality results with ingredients you can actually find at your regular grocery store, proving once and for all that fancy food doesn’t require a culinary degree or a trust fund.

Ingredients

For the Chicken Wellington

8 oz button mushrooms, trimmed and quartered
1¼ pounds boneless, skinless chicken breasts, thick (not thin-sliced) and air-chilled recommended
Kosher salt and freshly ground black pepper
2 teaspoons olive oil
2 tablespoons butter
1 small shallot, minced (about 1/4 cup)
1 teaspoon dried thyme leaves
2 garlic cloves, minced
1 pound puff pastry (9×9 sheets, thawed – 2 sheets per box)
3 tablespoons dijon mustard
1 large egg, lightly beaten

For the Dijon Cream Sauce

1 tablespoon butter
1 tablespoon minced shallot
1 cup vegetable broth
1 /3 cup heavy cream
1 tablespoon dijon mustard

Instructions

Preparation

1 Preheat the oven to 400°F (200°C). Using a food processor, process the mushrooms until minced very small, scraping down the sides of the bowl as needed. This creates the perfect texture for your mushroom duxelles – you want it finely chopped but not pureed.
2 Pat chicken breasts dry with paper towels and slice them in half horizontally, creating two separate roughly 4-inch breast portions. Season both sides lightly with kosher salt and freshly ground black pepper. The key here is getting evenly sized pieces that will cook at the same rate.

Searing and Building Flavors

3 Heat 1 teaspoon olive oil and 1 tablespoon butter in a large cast iron skillet or non-stick pan over medium-high heat until the butter is foaming. Sear chicken breasts for 2 minutes per side until golden brown but not cooked through – you’re looking for a beautiful caramelized exterior while keeping the interior pink since it will finish cooking in the oven.
4 Add the remaining 1 teaspoon olive oil and 1 tablespoon butter to the same pan. Add the minced mushrooms, shallot, garlic, thyme, and about 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Cook, stirring frequently, until the mixture is deeply browned and no liquid remains – this takes 6-8 minutes total. The mushrooms will release their moisture first, then concentrate into a rich, intensely flavored duxelles. Transfer to a bowl and let cool completely.

Assembly

5 Lightly flour a clean work surface or large cutting board and roll out the puff pastry into an 11-inch even square using a rolling pin. Cut the pastry into 2 equal squares. Place both squares onto a baking sheet lined with parchment paper, spacing them about 2 inches apart.
6 Spread about 1/4 cup of the cooled mushroom mixture on top of each puff pastry square, leaving about a 1-inch border around all edges. Place one chicken breast on top of each mushroom layer, then spread about 1 teaspoon dijon mustard over the top of each chicken breast, coating completely.
7 Working with one wellington at a time, fold one edge of the puff pastry over the chicken, then fold the opposite edge over it, overlapping slightly. Take the two remaining ends and fold them over each other, creating a tight pastry pocket with no holes or gaps. Secure with toothpicks if needed to prevent opening during baking. Brush the tops and sides generously with the beaten egg wash for that gorgeous golden finish.

Baking

8 Bake at 400°F (200°C) for 17-20 minutes, or until the puff pastry is golden brown and crispy, and the chicken reaches an internal temperature of 165°F (74°C). Cooking times will vary depending on the thickness of your chicken breasts – thicker pieces may need up to 22 minutes.

Making the Dijon Cream Sauce

9 While the wellington bakes, prepare the sauce. Melt 1 tablespoon butter in a medium saucepan over medium heat. Add the minced shallot and cook for 1 minute until fragrant. Add the vegetable broth, increase heat to medium-high, and simmer until reduced by half (about 1/2 cup remaining).
10 Stir in the heavy cream and continue simmering until thickened enough that a wooden spoon leaves a clear line when drawn through the sauce – about 3-4 minutes. Stir in the dijon mustard and season with kosher salt and black pepper to taste. The sauce will continue to thicken as it cools.
11 Remove wellington from oven and let rest for 2-3 minutes before serving. Serve immediately with the warm dijon cream sauce drizzled over or alongside.

Recommended Equipment and Kitchen Tools

Essential Tools (for best results):

Food processor – Creates the perfect fine texture for mushroom duxelles without over-processing into mush. A sharp knife and patience can substitute, but the food processor gives consistent results every time.
Cast iron skillet or heavy-bottomed non-stick pan – Provides even heat distribution for proper searing and developing that golden-brown crust on both chicken and mushrooms.
Rolling pin – Essential for achieving an even 11-inch square of puff pastry. A wine bottle can work in a pinch, but a proper rolling pin gives better control.
Instant-read thermometer – Takes the guesswork out of doneness, ensuring your chicken reaches exactly 165°F without overcooking.

Helpful Upgrades:

Kitchen scale – Professional bakers swear by weight measurements for consistent results, especially when working with puff pastry and portioning ingredients.
Silicone spatula – Perfect for scraping down the food processor bowl and getting every bit of that flavorful mushroom mixture.
Parchment paper – Prevents sticking and makes cleanup effortless, plus helps with even browning on the bottom of your wellington.

Nice-to-Have Options:

Pastry brush – Makes applying egg wash smooth and even, though a paper towel or clean fingers work just fine.
Bench scraper – Helpful for moving rolled pastry and keeping your work surface clean during assembly.

Finish with lemon tart or chocolate mousse for an impressive dinner party menu that flows beautifully from course to course.

Pro Tips and Troubleshooting

Professional Techniques:
The key to perfect wellington is moisture control – always let your mushroom mixture cool completely before assembly, and pat chicken extra dry before searing. Score the pastry lightly in a crosshatch pattern on top for professional presentation and better steam release. Chill assembled wellingtons for 15 minutes before baking if your kitchen is warm – this prevents the pastry from getting soggy.

Common Mistakes and Solutions:
Soggy bottom pastry happens when ingredients are too wet or the oven isn’t hot enough – always cook mushrooms until completely dry and ensure your oven is fully preheated. Pastry splitting occurs from overfilling or uneven folding – use less filling rather than more, and seal edges with water if needed. Overcooked chicken results from thick breasts or high oven temperature – use an instant-read thermometer and tent with foil if pastry browns too quickly.

Storage and Reheating:
Store leftover wellington in the refrigerator for up to 3 days. Reheat in a 350°F (175°C) oven for 8-10 minutes to restore pastry crispness – avoid microwaving as it makes pastry soggy. The mushroom duxelles can be made 2 days ahead and refrigerated.

Make-Ahead Strategy:
Assemble wellingtons completely and refrigerate for up to 4 hours before baking – just add 2-3 extra minutes to cooking time. The cream sauce can be made ahead and gently rewarmed, thinning with additional broth if needed.

Scaling Tips:
This recipe doubles easily for entertaining – use two baking sheets and rotate positions halfway through cooking for even browning. For larger crowds, consider making individual mini wellingtons using 4-inch pastry squares and 3-ounce chicken portions, reducing cooking time to 12-15 minutes.

This chicken wellington proves that restaurant-quality elegance is absolutely achievable in your home kitchen, delivering impressive results that taste even better than they look. The combination of flaky pastry, perfectly seasoned chicken, and that luxurious dijon cream sauce creates a dining experience that transforms any evening into something special, whether you’re cooking for two or hosting a dinner party that’ll have everyone asking for the recipe.
