Slathering mustard on chicken is one easy way to a juicy, flavorful bird. Like its creator, Ruth Cousineau, this dish revels in simplicity without being austere: Gild the lily by making a delectably creamy, mustardy gravy from the pan juices. The gravy, in turn, begs for mashed potatoes, and by adding a salad—voilà, the perfect Sunday dinner. (Editor's note: This recipe is solely the creation of Ruth Cousineau and has not been formally tested by the test kitchen.)

Preparation
Step 1
Preheat oven to 425°F with rack in middle.
Step 2
Pull off excess fat around cavities of chicken and discard, then rinse chicken and pat dry. Mix together 1 1/2 teaspoons salt and 1 teaspoon pepper and rub inside cavity. Chop enough tarragon to measure 1 1/2 tablespoons and set aside, then add remainder of bunch to cavity. Put chicken in a flameproof shallow roasting pan or gratin dish and rub all over with 1/3 cup mustard. Tie legs together with string and roast until an instant-read thermometer inserted into fleshy part of a thigh (do not touch bone) registers 170°F, 45 minutes to 1 hour.
Step 3
Carefully tilt chicken so juices from cavity run into roasting pan, then transfer chicken to a cutting board and let stand 10 minutes.
Step 4
Pour off all but 2 tablespoons fat from pan. Whisk in flour, then cook over medium heat, whisking, 1 minute. Add water, whisking constantly and scraping up brown bits, and bring to a boil. Simmer sauce until slightly thickened, then whisk in cream, remaining tablespoon mustard, and salt and pepper to taste.
Step 5
Strain sauce through a fine-mesh sieve into a bowl, discarding solids, then stir in reserved chopped tarragon. Serve chicken with sauce.
