I love a good sauce and this French mustard cream sauce is absolutely decadent. And guess what? You can make this dish quickly even if you forgot to thaw out the chicken. It uses basic ingredients I tend to always have on hand, too.

Chicken in French Mustard Cream Sauce

Ingredients

4-6 boneless chicken thighs (frozen is fine!)
1-2 tbsp olive oil
garlic salt and black pepper to taste
1/4 cup dry white wine
1/4 cup chicken broth
1 teaspoon Herbs de Provence
2 tbsp course ground Dijon mustard
2 tbsp regular Dijon mustard
1 tbsp flour or cornstarch plus water to make paste
1/2 cup heavy cream

Instructions

Set Instant Pot on sauté setting and add olive oil.
Brown seasoned, frozen chicken thighs in hot oil.
Deglaze pot with white wine, being careful to scrape up all the browned bits on the bottom of the Instant Pot. Turn IP off.
Add chicken broth and sprinkle chicken with Herbs de Provence.
Using manual setting, cook for 8 minutes, making sure vent is closed.
When chicken is done you can allow to release pressure naturally or use the quick release method.
Stir in both types of mustard.
Turn IP to sauté setting and bring to a boil. Allow sauce to reduce and thicken a bit. If it's very thin you can thicken with 1 tablespoon flour or cornstarch stirred into cold water to make a paste.
Stir in heavy cream, heat through and season with a bit of freshly ground black pepper.
Serve chicken with sauce spooned over.

I served this with a salad, glazed carrots and baked potatoes. The sauce is so delicious, however, that I would suggest rice, noodles or mashed potatoes so you can spoon the sauce over. Or at least have some good, crusty bread to sop up all that goodness.
