Step 1: Season the Chicken

• Pat the chicken dry with paper towels and season generously with salt and pepper on both sides.

Step 2: Layer in the Crockpot

• Place the sliced onions at the bottom of the slow cooker to create a flavorful base.
• Arrange the seasoned chicken thighs on top of the onions. Sprinkle the minced garlic over the chicken.

Step 3: Add Liquid and Seasonings

• Pour the chicken broth into the slow cooker. Sprinkle the dried thyme evenly over the chicken.
• If using optional veggies like mushrooms or carrots, add them now.

Step 4: Cook

• Cover and cook on low for 6–8 hours or high for 3–4 hours, until the chicken is tender and cooked through.

Step 5: Thicken the Gravy

• Remove the chicken from the slow cooker and set aside. Skim off any excess fat from the liquid if desired.
• In a small bowl, whisk together the flour and heavy cream until smooth. Stir this mixture into the slow cooker.
• Turn the slow cooker to high and let the gravy simmer uncovered for 10–15 minutes, stirring occasionally, until it thickens slightly.

Step 6: Serve

• Return the chicken to the slow cooker to coat it in the gravy, or serve the gravy alongside.
• Serve over mashed potatoes, egg noodles, or steamed rice. Garnish with fresh parsley if desired.
