Whisk the salt and sugar into the water until they are completely dissolved, add 3 stalks of Thyme. Place the chicken in a large bowl or pot and cover with the brine. Refrigerate over night or at least 2 hours, then remove it and dry well with a clean towel.
Preheat your oven to 350°F Toss the vegetables and onions with oil and a bit of salt and pepper then pour them into a casserole dish or shallow roasting pan along with the bay leaves. Sit the chicken on top and roast until the thermometer reads 160°F instantly in the thickest part of the breast and 165°F in the thigh. Take a brush and brush the Browning Gravy all over the chicken generously and let cook to the desired color.
Cooking time depends on the size of your chicken. Use the leftover thyme as garnish.
