How to Make Crockpot Mustard Chicken with Potatoes Recipe
Step 1: Season and Sear the Chicken
Start by seasoning your chicken thighs generously with salt and black pepper. Then, heat olive oil in a skillet over medium-high heat and sear the chicken skin side down until it’s gloriously golden brown, about 4 to 5 minutes per side. This step builds incredible flavor and texture before everything heads into the crockpot.
Step 2: Arrange Vegetables in the Crockpot
Once the chicken is seared, place it in your crockpot. Surround it with the halved baby potatoes and sliced yellow onion, nestling everything close together so they’ll cook evenly and soak up the delicious juices.
Step 3: Mix and Pour the Mustard Sauce
Whisk together the Dijon mustard, whole grain mustard, chicken broth, minced garlic, honey, and dried thyme in a bowl. Pour this vibrant mixture over the chicken and veggies, making sure every bite will be infused with that irresistible tangy, slightly sweet flavor.
Step 4: Slow Cook to Perfection
Cover your crockpot and cook on low for 6 to 7 hours, or on high for 3 to 4 hours. You’ll know it’s ready when the chicken is cooked through and tender, and the potatoes are soft and flavorful. The slow cooking melds all those great ingredients into something truly comforting.
Step 5: Stir in the Creamy Finish
About 20 minutes before serving, gently stir in the heavy cream to add a luscious, velvety texture that balances the mustard’s tang. Let it warm through for that perfect creamy consistency before plating.
How to Serve Crockpot Mustard Chicken with Potatoes Recipe

Garnishes
Nothing brightens up this dish like a sprinkle of freshly chopped parsley right before serving. It adds a pop of fresh green color and a hint of herbal freshness that cuts through the richness beautifully.
Side Dishes
This dish is satisfying on its own, but pairing it with a crisp green salad or steamed vegetables creates a nice balance. You could also serve crusty bread on the side to soak up the delicious mustard sauce—trust me, no sauce left behind!
Creative Ways to Present
For a dinner party, try serving the chicken thighs atop a bed of creamy mashed potatoes or buttery polenta, spooning the mustard sauce and potatoes over the top for a restaurant-worthy presentation. You can also plate the potatoes first, arrange the chicken neatly, and finish with parsley to impress your guests.
Make Ahead and Storage
Storing Leftovers
Leftovers of this Crockpot Mustard Chicken with Potatoes Recipe keep wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors even deepen overnight, making your next meal just as tasty if not better.
Freezing
If you want to set aside portions for busy days, you can freeze this dish (without the cream) in freezer-safe containers for up to 3 months. When ready to eat, thaw overnight in the fridge before reheating gently and stirring in cream fresh.
Reheating
Reheat leftovers on the stovetop over low heat, stirring occasionally to prevent sticking. Add a splash of broth or water if the sauce thickens too much. This will help restore the creamy, saucy texture that makes this meal so comforting.
FAQs
Can I use boneless chicken thighs instead?
Absolutely! Boneless chicken thighs work well and will cook a bit faster. Just watch the cooking time to avoid drying them out, reducing low heat cooking to about 4 to 5 hours.
Is there a way to make the sauce thicker?
Yes, if you prefer a thicker sauce, remove the crockpot lid during the last 20 to 30 minutes of cooking to allow some liquid to evaporate. This will concentrate the flavors and thicken the sauce naturally.
Can I substitute the heavy cream?
You can use half-and-half or a dairy-free cream alternative if you want to lighten the dish or need a dairy-free option. Just be aware the sauce may be a little less rich but still delicious.
What would be a good wine pairing with this dish?
A crisp, chilled white wine like Sauvignon Blanc or Chardonnay complements the tangy mustard flavors and balances the richness of the chicken nicely.
Can I add other vegetables?
Definitely! Carrots, parsnips, or green beans can be added around the chicken for extra color and nutrition. Just adjust cooking times slightly if adding firmer veggies.
