Chicken Wellington Ingredients
For the Filling

- 1¼ pounds boneless, skinless chicken breasts – Provides lean protein; air-chilled chicken is recommended for better texture.
- Kosher salt and freshly ground black pepper – Enhances flavor; adjust to taste.
- 2 teaspoons olive oil – Used for sautéing; any neutral oil can be substituted.
- 2 tablespoons butter – Adds richness to the filling; plant-based margarine works for a dairy-free option.
- 1 small shallot, minced (about ¼ cup) – Contributes sweetness and depth; you can use onion if shallots are unavailable.
- 1 teaspoon dried thyme leaves – Adds earthy aroma; fresh thyme can be used (about 3 teaspoons).
- 2 garlic cloves, minced – Imparts flavor and aroma; adjust according to preference.
- 1 pound 9×9 puff pastry sheets, thawed (2 sheets per box) – Creates the flaky exterior; ensure quality brands that accommodate dietary needs are selected.
- 3 tablespoons dijon mustard – Provides a tangy kick; whole grain mustard offers a different flavor twist.
- 1 large egg, lightly beaten – Used for egg wash to achieve a golden finish; skip for a vegan option.
For the Dijon Cream Sauce
- 1 tablespoon butter – Adds richness; substitute with oil for a dairy-free version.
- 1 tablespoon minced shallot – Deepens flavor in the sauce; use onion as a substitute if needed.
- 1 cup vegetable broth – A base for the sauce that enhances depth; chicken broth can be used for a non-vegetarian option.
- ⅓ cup heavy cream – Offers creaminess to the sauce; coconut cream is a great dairy-free alternative.
- 1 tablespoon dijon mustard – Maintains flavor consistency in the sauce, perfect for complementing your Chicken Wellington!
Step‑by‑Step Instructions for Chicken Wellington
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This step ensures that your Chicken Wellington will bake evenly and achieve that perfect golden-brown crust. While the oven heats up, prepare the ingredients, so everything is ready for easy assembly once you start cooking.
Step 2: Prepare the Mushroom Filling
In a food processor, finely chop the 8 oz of button mushrooms until they resemble a coarse paste. Once chopped, transfer them to a skillet with 2 teaspoons of olive oil and 2 tablespoons of butter over medium heat. Sauté for about 6-8 minutes until they begin to brown and their liquids evaporate. Set aside to cool.
Step 3: Sear the Chicken
Season the 1¼ pounds of boneless, skinless chicken breasts generously with kosher salt and freshly ground black pepper. In the same skillet, add a little more oil if needed, and sear the chicken over medium-high heat for approximately 2 minutes per side, until golden brown but not fully cooked. This will enhance the flavor of your Chicken Wellington.
Step 4: Cook the Aromatics
In the same skillet, add the minced shallot, 2 cloves of minced garlic, and 1 teaspoon of dried thyme leaves to the mushrooms. Cook everything together for another 4-5 minutes until the mixture is fragrant and the shallots are translucent. Allow this mixture to cool, as it will blend with the chicken later.
Step 5: Roll Out the Puff Pastry
On a lightly floured surface, roll out the thawed puff pastry sheets until they’re about an 11-inch square. Using a sharp knife, divide the sheet into four equal squares. This will create the perfect parcels to envelop your Chicken Wellington, so take your time to ensure even cuts.
Step 6: Assemble the Wellingtons
Lay the rolled pastry squares on a baking sheet lined with parchment paper. Place a layer of the cooled mushroom mixture in the center of each square, then top it with the seared chicken breast and 3 tablespoons of dijon mustard. Fold the pastry over the filling, sealing the edges securely to contain all those delicious flavors.
Step 7: Brush and Bake
Brush the assembled Chicken Wellingtons with the lightly beaten egg for a shiny, golden finish. Place them into your preheated oven and bake for 17-20 minutes, or until the pastry is puffed and golden brown, with an internal temperature of the chicken reaching 165°F.
Step 8: Make the Dijon Cream Sauce
While the Chicken Wellington is baking, prepare the creamy dijon sauce. In a small saucepan, melt 1 tablespoon of butter over medium heat, then add 1 tablespoon of minced shallot. Sauté for about 2 minutes. Pour in 1 cup of vegetable broth and let it simmer. After reducing it slightly, stir in ⅓ cup of heavy cream and 1 tablespoon of dijon mustard. Season to taste.
Step 9: Serve and Enjoy
Once the Chicken Wellington is beautifully golden and cooked through, remove it from the oven. Serve each Wellington hot, drizzled with the creamy dijon sauce for an impressive and delightful meal that’s sure to impress your guests.

How to Store and Freeze Chicken Wellington
Fridge: Store leftover Chicken Wellington in an airtight container for up to 3 days. This will help maintain the flakiness of the pastry while keeping the filling fresh.
Freezer: For longer storage, freeze the Chicken Wellington before baking. Wrap each Wellington tightly in plastic wrap, then place in a freezer bag for up to 6 months. When ready, bake from frozen, adding an extra 5-10 minutes to the cooking time.
Reheating: To reheat, place the Chicken Wellington in a preheated oven at 350°F (175°C) for about 15-20 minutes or until warmed through. Avoid microwaving to keep the pastry crisp.
Preparation Tip: If you’re preparing the chicken filling ahead of time, keep it stored separately from the pastry and assemble just before baking for the best texture.

Chicken Wellington Recipe FAQs
How do I know if my mushrooms are ripe?
Absolutely! Look for mushrooms that are firm and dry with a smooth surface. Avoid any with dark spots or leakage, as they might be past their prime. For button mushrooms, choose ones that have a fresh, light earthy scent.
What is the best way to store leftover Chicken Wellington?
You can refrigerate leftovers in an airtight container for up to 3 days. This keeps the pastry flaky and the filling fresh. When reheating, it’s best to use the oven at 350°F (175°C) for about 15-20 minutes to maintain crispiness.
Can I freeze Chicken Wellington? If so, how?
Yes, you can definitely freeze Chicken Wellington! Wrap each unbaked Wellington tightly in plastic wrap and store them in a freezer bag for up to 6 months. When you’re ready to bake them, preheat your oven to 400°F (200°C) and bake the frozen Wellingtons for an extra 5-10 minutes, making sure to check that the chicken reaches 165°F.
What should I do if my pastry leaks during baking?
Very good question! To prevent leaks, ensure that the pastry edges are sealed tightly before baking. If you experience leaks, you can place a baking sheet underneath to catch any drips. Additionally, using toothpicks can help to keep the pastry secured while baking if needed.
What are some dietary considerations for Chicken Wellington?
I recommend using plant-based margarine instead of butter for a dairy-free version. For gluten-free options, look for puff pastry that accommodates such diets, and be cautious with ingredients if you or your guests have any specific allergies. Always check labels to ensure safety!
