Creamy Mustard Chicken

Creamy mustard chicken is the bistro-style dinner that turns chicken breast into something worth ordering twice. Strips of chicken breast sear in olive oil with garlic, then a sauce builds in the same pan from the cream that loosens the fond, mustard for sharp punch, and a flour slurry for silky body.

Coarse-grain mustard is the move here, not smooth Dijon. The whole mustard seeds add visible texture and pop with little bursts of pungent flavor, transforming the sauce from generic-creamy to French-bistro-styled. Smooth mustard works in a pinch but you lose that signature character.

The slurry technique (mixing flour with a bit of cream before adding) prevents lumps from forming when the flour hits hot liquid. Two minutes of stirring after the slurry goes in is all it takes to thicken into a clingy, glossy sauce. Garnish with fresh parsley and serve immediately.

Pro Tips

• Cook the chicken strips just until done, about 10 minutes total. Overcooked chicken breast turns dry and rubbery, especially after a final reheat in the sauce.
• Don’t crowd the pan. Cook the chicken in batches if needed. Crowding causes the meat to steam in its own juices instead of browning.
• Use light cream (half-and-half), not heavy cream, as the recipe specifies. Heavy cream makes the sauce too rich and the mustard gets buried in the fat.
• The sauce thickens slightly more as it cools off heat, so pull it from the burner the moment it coats the back of a spoon.

Variations

• Stir in a tablespoon of fresh tarragon or thyme with the mustard for an herbal lift.
• Add a splash of dry white wine to deglaze the pan after removing the chicken, before adding the cream.
• Serve over pasta or with rice and steamed vegetables for a complete dinner.
