Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the chicken
700 g (1.4 lb) skinless, boneless chicken thigh fillets (4–6 pieces)
1 1/2 tablespoons olive oil
1/2 teaspoon cooking or kosher salt
1/4 teaspoon black pepper
For the creamy mustard sauce
1/2 cup (125 ml) thickened or heavy cream
1 tablespoon Dijon mustard
1 tablespoon wholegrain mustard
1/4 teaspoon cooking or kosher salt
1/4 teaspoon black pepper
1–2 tablespoons water, as needed
Season the chicken
Pat the chicken dry with paper towels. Season both sides evenly with salt and black pepper.
Sear the chicken
Heat olive oil in a large heavy-based pan over medium-high heat. Use a pan that is not non-stick to allow flavorful browned bits to develop.
Place the chicken smooth side down and cook for 4 minutes until deep golden. Flip and cook for another 3–4 minutes until fully cooked. The internal temperature should reach 72°C (162°F) for thighs.
If using chicken breast (cut in half horizontally and pounded to 1 cm thickness), cook on high heat for 2 minutes per side until it reaches 67°C (153°F).
Transfer the cooked chicken to a plate and allow it to rest.
Clean the pan
Scrape out any loose burnt bits, leaving behind the golden brown fond stuck to the pan.
Make the sauce
Reduce heat to medium. Add the heavy cream, Dijon mustard, and wholegrain mustard to the pan. Stir continuously, scraping up the browned bits from the bottom.
Heat until the sauce is hot but not boiling. Dijon mustard will naturally thicken the sauce, so no long simmering is required.
Stir in salt, pepper, and optional fresh herbs. If the sauce becomes too thick, add 1 tablespoon of water at a time until desired consistency is reached.
Serve
Place the chicken on serving plates and spoon the creamy mustard sauce generously over the top. Serve immediately.

Variations
Use chicken breast instead of thighs
Slice two chicken breasts horizontally to create four thin steaks and pound evenly before cooking.
Add garlic
Sauté 1 minced garlic clove in the pan for 30 seconds before adding the cream for added depth.
Make it lighter
Use pouring cream instead of heavy cream, though the sauce will be thinner and less rich.
Add mushrooms
Sauté sliced mushrooms after removing the chicken, then proceed with the sauce.
Try different herbs
If tarragon is unavailable, fresh chives or thyme can provide a different but pleasant herbal note.
Use alternative proteins
This sauce works well with turkey steaks or firm white fish fillets using the same cooking method.
Storage/Reheating
Refrigeration
Store cooked chicken and sauce in an airtight container in the refrigerator for up to 3–4 days.
Freezing
Freezing is not recommended as cream-based sauces can separate and become grainy when thawed.
Reheating
Reheat gently in a pan over low heat until warmed through. Add a small splash of water or cream to loosen the sauce if needed. Avoid high heat to prevent the sauce from separating.
FAQs
Can I use chicken breast instead of thighs?
Yes. Slice each breast horizontally into two thin pieces and cook for about 2 minutes per side.
Why shouldn’t I use a non-stick pan?
A regular pan allows browned bits to form on the bottom, which dissolve into the sauce and add flavor.
Can I make this without wholegrain mustard?
Yes. Increase the Dijon mustard slightly to compensate, though the texture will be smoother.
What does tarragon taste like?
Tarragon has a mild anise-like flavor with subtle sweetness that pairs beautifully with cream.
How do I know when the chicken is fully cooked?
Use a thermometer. Thighs should reach 72°C (162°F) before resting.
Can I make the sauce thicker?
The Dijon mustard naturally thickens the sauce. If needed, simmer briefly or reduce slightly.
Yes, but for best texture and flavor, reheat gently and avoid overcooking.
Is low-fat cream suitable?
It works, but the sauce will be thinner and less rich.
Can I double the sauce?
Absolutely. Simply double all sauce ingredients while keeping cooking times the same.
