These crockpot creamy mustard chicken thighs cook with tart apples, tender shallots, and thyme before finishing in a rich mustard cream sauce. Serve them over brown butter mashed potatoes with bacon mushroom green beans for a comforting dinner that’s easy enough for a weeknight.
The apple softens into the broth as the chicken cooks, adding a little sweetness to balance the mustard. Thinly sliced shallots bring a mellow onion flavor, and a splash of heavy cream at the end pulls everything together.
You can give the thighs a quick sear first for golden color and deeper flavor, or skip that step when you need an easier start. Either way, keep something on the plate to catch that creamy mustard, apple, and shallot sauce.

Ingredients for Creamy Mustard Chicken Thighs
Chicken Thighs
Bone-in, skin-on chicken thighs give this dish plenty of flavor. Searing them first adds color, although the skin will soften during slow cooking.
Shallots
Thinly sliced shallots soften into the sauce and add a gentle onion flavor that works well with the apple and mustard.
Granny Smith Apple
A peeled, finely diced Granny Smith apple adds tartness and a little sweetness. Small pieces soften more evenly and blend into the finished sauce.
Chicken Broth
The broth provides the cooking liquid and forms the base of the mustard cream sauce. Use low-sodium broth if you prefer more control over the seasoning.
Spicy Brown Mustard
Spicy brown mustard adds tang and savory flavor. Dijon also works well if that’s what you have.
Thyme
A little thyme complements the chicken, apples, and shallots. Use fresh or dried.
Heavy Cream
Stir the cream in near the end of cooking for a silky finish.
Optional Cornstarch Slurry
Chicken releases liquid as it cooks. If you prefer a thicker sauce, a little cornstarch mixed with cold water helps give it more body.
How to Make Crockpot Creamy Mustard Chicken Thighs
1. Season and Sear the Chicken
Pat the chicken thighs dry and season with the salt and pepper.
For golden color and extra flavor, place the thighs skin-side down in a large skillet over medium-high heat. Cook for about 5–6 minutes, until the skin is browned and releases easily. Work in batches as needed, then transfer the chicken to the slow cooker.
The sear is optional, but it gives the finished dish a richer flavor.
2. Add the Apple, Shallots, and Mustard
Scatter the sliced shallots and diced apple around the chicken.
Stir the mustard and thyme into the chicken broth, then pour it around the thighs.
3. Slow Cook Until Tender
Cover and cook on LOW for approximately 6–7 hours or HIGH for approximately 3–4 hours.
Cooking time varies with the size of the thighs and your slow cooker. Check the thickest part of the chicken with a meat thermometer, avoiding the bone; it should reach at least 165°F.
4. Finish the Mustard Cream Sauce
During the last 20–30 minutes, gently stir the heavy cream into the cooking liquid around the chicken.
For a thicker sauce, mix the cornstarch with cold water until smooth, then stir it into the sauce. Cover and cook until the sauce has thickened to your liking, using HIGH for the finish if needed.
Taste and adjust the seasoning before serving.
5. Spoon Over the Sauce and Serve
Serve the chicken with generous spoonfuls of the creamy mustard sauce, making sure each plate gets some softened apples and shallots.
Tips for the Best Slow Cooker Mustard Chicken
Sear for color and flavor. Slow cooking won’t brown the chicken skin, so sear first if you want a golden finish.
Expect tender skin rather than crispy skin. The covered, moist cooking environment softens the skin even when the chicken is browned beforehand.
Add the cream toward the end. This gives you better control over the finished sauce.
Dice the apple small. Smaller pieces soften into the sauce instead of remaining firm.
Adjust the sauce after cooking. The amount of liquid released by the chicken can vary. Add the optional slurry only if the sauce needs thickening.
For a crisper finish, use the broiler. Transfer the cooked thighs to a broiler-safe baking sheet and broil briefly, watching closely. Spoon the cream sauce over the chicken afterward.
What to Serve with Creamy Mustard Chicken
My first choice is brown butter mashed potatoes. They’re a natural match for the savory mustard cream sauce and make this feel like a complete Sunday dinner.
For a green vegetable, try bacon mushroom green beans, or keep things simple with steamed green beans like the plated serving shown here.
Buttered egg noodles, rice, and crusty bread are also good options for catching the extra apple and shallot sauce.

- Total Time: 6 hours 15 minutes
- Yield: 4–6 servings 1x
- Category: Dinner
- Method: Crockpot
- Cuisine: American
Ingredients
- 8 bone-in, skin-on chicken thighs
- ¾ teaspoon salt
- ½ teaspoon black pepper
- 2 shallots, thinly sliced
- ½ Granny Smith apple, peeled and finely diced
- ½ cup low-sodium chicken broth
- 1 tablespoon spicy brown mustard or Dijon mustard
- ½ teaspoon fresh thyme leaves, or ¼ teaspoon dried thyme
- ½ cup heavy cream
- 1 tablespoon cornstarch mixed with 1 tablespoon cold water, optional
Instructions
- Pat the chicken thighs dry with paper towels. Season with salt and pepper.
- Heat a large nonstick or well-seasoned skillet over medium-high heat. Place the chicken skin-side down in the skillet and sear for 5–6 minutes, until golden brown. Work in batches to avoid crowding. The chicken will finish cooking in the slow cooker.
- Place the sliced shallots and diced apple in the slow cooker. Arrange the seared chicken thighs over them, skin-side up.
- Whisk together the chicken broth, mustard, and thyme. Pour around the chicken.
- Cover and cook on LOW for approximately 6–7 hours or HIGH for 3–4 hours, until the chicken is tender and the thickest part reaches at least 165°F without touching the bone. Cooking times vary; begin checking earlier if your slow cooker runs hot.
- During the last 20–30 minutes, gently stir the heavy cream into the cooking liquid around the chicken.
- For a thicker sauce, stir together the cornstarch and cold water until smooth. Gently stir the slurry into the sauce. Cover and cook on HIGH for 15–20 minutes, or until thickened.
- Taste the sauce and adjust the seasoning. Serve the chicken with mashed potatoes and green beans, spooning the mustard, apple, and shallot cream sauce over and around the chicken.
Notes
- Optional searing: You can skip searing, but the chicken will have a paler appearance and less browned flavor.
- Chicken skin: The skin softens during slow cooking. For a crisper finish, transfer the cooked thighs to a broiler-safe baking sheet and broil briefly, watching closely. Add sauce afterward.
- Mustard: Spicy brown mustard and Dijon both work. Taste the finished sauce before adding more.
- Boneless thighs: These may cook faster. Begin checking earlier and use a thermometer to confirm doneness.
- Sauce consistency: Chicken releases juices during cooking. Use the optional slurry if the sauce is thinner than you prefer.
- Storage: Refrigerate leftovers in an airtight container for up to 3–4 days. Reheat gently with a splash of broth as needed.
- Timing: The listed cook time allows approximately 6 hours of slow cooking plus 30 minutes to finish the sauce. Allow longer as needed.
- Mashed potatoes and green beans are serving suggestions and are not included in the ingredient amounts.
Substitutions and Variations
Use Dijon mustard: Substitute the same amount of Dijon for the spicy brown mustard.
Use boneless chicken thighs: Boneless thighs work, but may finish sooner. Begin checking them earlier and use a thermometer to judge doneness.
Use another firm apple: A firm sweet-tart apple can replace Granny Smith. The finished sauce may taste a little sweeter.
Use dried thyme: Substitute ¼ teaspoon dried thyme for the ½ teaspoon fresh thyme.
Storing and Reheating Leftovers
Refrigerate leftover chicken and sauce in an airtight container for up to 3–4 days.
Reheat gently on the stovetop or in the microwave until hot throughout. Add a splash of chicken broth if the sauce has thickened, and stir gently to bring it back together.
Frequently Asked Questions
Can I skip browning the chicken before putting it in the crockpot?
Yes. Searing adds flavor and golden color, but you can skip it. The chicken will have a paler appearance, and the skin will remain soft.
Can I use Dijon mustard instead of spicy brown mustard?
Yes. Use 1 tablespoon Dijon in place of the spicy brown mustard. Taste the finished sauce before adding more.
Will the chicken skin stay crispy in the slow cooker?
No. The moisture in the slow cooker softens the skin. For a crisper finish, briefly broil the cooked thighs on a broiler-safe baking sheet before serving.
Why is my mustard cream sauce thin?
Chicken releases juices during cooking, which can thin the sauce. Stir in the optional cornstarch slurry near the end and allow it to heat through and thicken.
Can I use chicken breasts?
You can, but they need a different cooking time and can dry out more easily. Start checking sooner and remove them when the thickest part reaches 165°F.
Does the apple make this chicken sweet?
The apple adds a mild sweetness, balanced by the mustard, broth, and shallots. Granny Smith keeps the sauce on the savory side.
An Easy Chicken Dinner to Keep on Repeat
