Before you start
Before starting, ensure all raw chicken is handled safely by keeping it chilled until the moment it is placed in the slow cooker. Wash your hands thoroughly after touching raw poultry and clean all surfaces, cutting boards, and knives that came into contact with the raw meat to prevent cross-contamination.
Prepare the carrots and onions by slicing them into even, bite-sized pieces; this consistency is key for ensuring they reach the perfect level of tenderness without turning to mush during the slow cooking process.

- 1 cup sliced onions
- 3 tbsp whole grain mustard
- 1/2 cup heavy cream
- 1/2 cup chicken broth
Instructions
Assembling the Ingredients
- Prepare the Slow CookerPlace the raw chicken legs into the base of the slow cooker. Scatter the sliced carrots and onions evenly over and around the chicken pieces.Look for Chicken should be arranged in a single layer if possible to ensure even cooking.Tip Ensure the slow cooker is clean before starting to prevent any cross-contamination.
At this stage, the slow cooker should be neatly packed with chicken, carrots, and onions. The ingredients should be distributed evenly to allow the heat to penetrate correctly. Ensure no chicken or vegetable pieces are sticking out of the top, as they need to be partially submerged in the liquid to remain moist. Everything is now ready for the addition of the creamy mustard sauce base.
Creating the Sauce
- Add Aromatics and LiquidDollop the whole grain mustard over the chicken and vegetables. Pour the heavy cream and chicken broth over the top of the mixture.Look for The liquid should partially submerge the chicken and vegetables for proper braising.Tip Whisk the cream and broth together in a measuring cup before pouring for a more uniform sauce consistency.
Once the mustard, cream, and broth are added, the slow cooker will contain a rich, layered base. The liquid should be visible around the edges of the chicken. Verify that the mustard is distributed evenly across the surface of the meat. The slow cooker is now ready to be covered, sealing in the moisture and flavors for the upcoming braising period, ensuring a tender and flavorful final result.
Cooking to Perfection
- Cook and ServeCover and cook on low for 4 to 6 hours or high for 3 hours. Verify the chicken reaches an internal temperature of 165°F (74°C) before serving. Let the chicken rest for 5 minutes before plating.Look for The chicken is done when the meat pulls away easily from the bone and the sauce has thickened slightly.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Serve immediately with the creamy sauce spooned over the chicken.
As the cooking concludes, the kitchen will be filled with a savory, aromatic scent. The chicken should be tender, the carrots soft, and the sauce thickened into a creamy, glossy consistency.
Before serving, verify the internal temperature of 165°F (74°C). The dish is ready once the meat is tender and the sauce has reached the desired thickness, providing a comforting and cohesive meal for serving.
Common mistakes
A common mistake is overcrowding the slow cooker, which prevents even circulation of heat and can lead to unevenly cooked chicken. Ensure the chicken pieces are arranged in a single layer so each piece is equally exposed to the heat.
Another error is failing to reach the safe internal temperature; always use a reliable thermometer. Finally, avoid lifting the lid too frequently during the cooking process, as this releases heat and moisture, significantly increasing the total cooking time and potentially drying out the meat.
How to tell it’s done
The chicken is fully cooked when it reaches an internal temperature of 165°F (74°C) as measured by a meat thermometer inserted into the thickest part of the leg, avoiding the bone. Visually, the meat should be opaque and pull away easily from the bone with a fork.
The sauce should be glossy and slightly thickened, coating the back of a spoon. If the sauce appears too thin, you can remove the chicken and simmer the liquid on the stovetop for a few minutes.
- Poultry: 165°F (74°C) in the thickest part
