Ingredients for the Recipe
For the chicken and sauce:
- 4 chicken breasts
- 300g mushrooms (Parisian Café type)
- 2 shallots, finely chopped
- 5 garlic cloves, minced
- 20g flat-leaf parsley, chopped
- 2 tbsp Dijon mustard
- 200ml light cream (15%)
- 50ml cognac for flambéing
- 400ml clear chicken stock
- 20g butter
- Salt and pepper
- 1kg yellow-fleshed potatoes
- 80g butter
- 150ml milk
- Nutmeg, to taste
- 20g salt for the cooking water (10g/L for 2L of water)
Prepare All Ingredients
Before starting, take a moment to organize your ingredients. Mise en place is key to stress-free cooking. Make sure you have everything ready:
- Peel and chop the potatoes.
- Gently clean the mushrooms with a brush or a damp paper towel (avoid soaking them in water). Trim the stems and slice.
- Finely chop the shallots, garlic, and parsley.
Tip: Keep your kitchen clean by placing peels and scraps in a plate as you go, ensuring your workspace stays tidy.
Preparing the Mashed Potatoes
Mashed potatoes are the perfect side to accompany this creamy mustard chicken. Here’s how to make them:
- Peel and chop the potatoes into even-sized chunks for consistent cooking.
- Cook in salted water: Add 20g of salt to 2L of cold water, then bring to a boil. Let the potatoes cook for about 20-28 minutes, until soft.
- Mash with butter and milk: Once tender, drain the potatoes and mash them. Stir in the butter, nutmeg to taste, and hot milk to achieve a smooth yet light texture.
- Keep warm: Cover the pot to keep the mashed potatoes hot until you’re ready to serve.

Preparing the Creamy Mustard Chicken
Now it’s time to focus on the star of the dish—the chicken with its creamy sauce:
- Sear the Chicken
Heat a heavy-bottomed pan to 200°C.
Add a thin layer of fat (duck fat or neutral oil).
Place the chicken breasts into the hot pan. Season with salt and cook until golden on both sides. - Flambé with Cognac
Once the chicken is nicely browned, pour the cognac over the meat. Carefully tilt the pan to ignite the alcohol. Always have a lid on hand to extinguish the flames if needed. - Cook the Mushrooms and Make the Sauce
After flambéing, remove the chicken from the pan and add a knob of butter.
Sauté the shallots and garlic until translucent. Add the mushrooms and cook for a few minutes until tender.
Return the chicken to the pan, pour in the chicken stock, and cover. Let it simmer for about 20 minutes to allow the flavors to meld. - Add the Cream and Mustard
Once the chicken is cooked through, uncover the pan. Add the cream and Dijon mustard. Whisk to create a smooth, creamy sauce.
Let the sauce reduce slightly over medium heat to thicken. For a thicker, richer sauce, let it reduce further.
Stir in the chopped parsley and mix well to combine.
Plating and Presentation Tips
Presentation is as important as taste! Here’s how to plate this dish beautifully:
- Slice the chicken on the diagonal to showcase its perfect cooking. Arrange the pieces on the plate.
- Add a scoop of mashed potatoes, using an ice cream scoop for a neat shape.
- Spoon the creamy mushroom sauce over the chicken and allow it to spill slightly onto the mashed potatoes.
- Sprinkle with fresh parsley for a burst of color and a hint of freshness.
Tip: Add a side of green salad or steamed vegetables (such as green beans) for a balanced meal.
Tips and Substitutions
Ingredient Substitutions:
- Mushrooms: If you can’t find Café de Paris mushrooms, feel free to use button mushrooms or portobellos.
- Cognac: You can swap it with dry white wine if you prefer a non-flambé version.
- Light cream: For a lighter version, opt for 5% fat cream or Greek yogurt.
Tips for Always Juicy Chicken:
- Pat the chicken dry before searing it. This ensures even browning.
- Avoid covering the sauce for too long while reducing, as it helps maintain a beautiful creamy consistency.
