Chicken with mustard sauce is a 20-minute skillet dinner that tastes like far more effort than it takes. Seared chicken breasts rest under a quick pan sauce of shallots, chicken stock, Dijon, and red wine vinegar, sharpened with thyme and tarragon. Bright, savory, and completely grain-free.
Chicken With Mustard Sauce
1 to 1½ pounds boneless, skinless chicken breasts
2 teaspoons (10 ml) minced fresh thyme
1 teaspoon (5 ml) dried tarragon
Salt and freshly ground black pepper, to taste
1 tablespoon (15 ml) oil or cooking fat of choice, plus 1 tablespoon (15 ml) for sauce
1 to 2 small shallots, peeled and minced
¼ cup chicken stock
2 tablespoons (30 ml) Dijon mustard
1 tablespoon (15 ml) red wine vinegar
- Season the chicken breasts with thyme, tarragon, salt and pepper.
- Heat 1 tablespoon (15 ml) of the oil over medium-high heat in a large skillet that is already hot. Add the chicken breasts and cook for 4 to 5 minutes per side, or until the chicken is cooked through and has browned. Remove to a large plate and keep warm.
- To the skillet add the remaining 1 tablespoon (15 ml) oil and the shallots and stir, scraping up any browned bits left by the chicken. Stir in the chicken stock, mustard and vinegar, combining well.
- Serve the chicken topped with the mustard sauce.
VARIATIONS: If you prefer a creamy mustard sauce, add about a ½ cup of coconut milk in step 3.
Pro Tips
- Get the skillet properly hot before the oil and chicken go in. A real sear gives the breasts their golden crust and leaves the fond the sauce is built on.
- Scrape up the browned bits when the shallots hit the pan - that fond is where most of the sauce's flavor lives.
- For a creamier mustard sauce, add about 1/2 cup of coconut milk when you stir in the stock, mustard, and vinegar.
- Let the cooked chicken rest on a warm plate while you make the sauce so the juices stay in the meat instead of running onto the board.
- Fresh thyme with dried tarragon gives the best balance. If you use fresh tarragon, halve the amount since it is much more assertive.
Frequently Asked Questions
Can I make chicken with mustard sauce ahead of time?
Yes - cook the chicken and sauce up to 2 days ahead and refrigerate them together. Rewarm gently in a skillet, adding a splash of stock to loosen the sauce if needed.
Is this recipe paleo and gluten-free?
It is. The sauce relies on reduction and Dijon rather than flour or dairy. Just check your Dijon mustard label if you avoid certain additives.
Can I use chicken thighs instead of breasts?
Absolutely. Thighs stay even juicier and love the tangy mustard pan sauce - give them an extra minute or two per side to cook through.
What should I serve with chicken and mustard sauce?
The sauce is made for spooning over roasted vegetables, cauliflower rice, or a simple green salad alongside the chicken.
