Slow Cooker Honey Mustard Chicken

Featured in: Simple Family Plates

This easy slow cooker meal features chicken breasts swimming in a rich honey mustard sauce. The combination of Dijon and whole grain mustard creates depth, while honey adds sweetness and garlic provides savory notes. After hours of gentle cooking, the meat becomes fork-tender and juicy. A simple cornstarch slurry thickens the sauce right before serving, resulting in a velvety coating perfect for drizzling over rice, mashed potatoes, or roasted vegetables.

The slow cooker was humming quietly on the counter when I realized I'd forgotten to defrost anything for dinner. I rummaged through the pantry, found honey and mustard, and decided to trust my instincts. Four hours later, the kitchen smelled like a bistro, and my family looked at me like I'd been hiding culinary secrets. That accidental evening became our most requested weeknight meal.

I made this for a friend recovering from surgery, and she called me later that week asking for the recipe. She said it reminded her of comfort without feeling heavy, which is exactly what she needed. Now I double the batch whenever someone needs a meal dropped off.

Ingredients

  • Boneless, skinless chicken breasts: Pat them dry before cooking so the sauce clings better, and trim any uneven bits so they cook evenly.
  • Dijon mustard: This is the backbone of the sauce, providing sharpness and body without being overpowering.
  • Honey: Use real honey, not the squeeze bottle imitation, it makes the sauce glossy and balances the tang beautifully.
  • Whole grain mustard: Those little seeds add texture and a subtle pop of flavor that keeps each bite interesting.
  • Apple cider vinegar: Just a tablespoon brightens everything and cuts through the sweetness with a gentle acidity.
  • Worcestershire sauce: It adds umami depth, the kind of savory note you cant quite name but definitely miss if its gone.
  • Garlic: Fresh minced garlic is worth the effort, it perfumes the sauce as it cooks and mellows into sweetness.
  • Onion powder: A quiet player that rounds out the savory base without adding moisture or bulk.
  • Paprika: Just a pinch for color and a whisper of warmth, nothing aggressive.
  • Chicken broth: Low sodium is key so you control the salt, and it thins the sauce just enough to coat without drowning.
  • Cornstarch: Mixed with cold water, it transforms the thin sauce into something luscious and spoonable at the end.

Prep the chicken:
Trim any excess fat and pat the breasts dry with paper towels. This helps the sauce stick and prevents the dish from getting watery.
Make the sauce:
Whisk together the Dijon, honey, whole grain mustard, vinegar, and Worcestershire until smooth, then stir in the garlic and spices. Add the chicken broth and whisk until everything is glossy and combined.
Assemble in the slow cooker:
Lay the chicken breasts in a single layer at the bottom of the slow cooker. Pour the honey mustard sauce over them, making sure each piece is coated.
Cook low and slow:
Cover and cook on low for 4 hours or high for 2 to 2.5 hours. The chicken should be tender and cooked through, with the sauce bubbling gently around the edges.
Thicken the sauce:
Remove the chicken and set it aside loosely covered. Mix the cornstarch with cold water to make a slurry, stir it into the sauce, then cook on high for 10 to 15 minutes, stirring once or twice, until it thickens.
Finish and serve:
Return the chicken to the slow cooker, spoon the thickened sauce over the top, and let it reheat for a couple of minutes. Serve hot with rice, mashed potatoes, or roasted vegetables.

One evening, I served this over buttery mashed potatoes, and my youngest asked if we could eat like this every night. It wasn't fancy, but the way everyone went quiet while eating told me everything I needed to know. Some recipes earn their place not because they're complicated, but because they make ordinary nights feel special.

Serving Suggestions

This chicken begs for something to soak up the sauce, so I reach for fluffy white rice, creamy mashed potatoes, or even buttered egg noodles. A simple side of steamed green beans or roasted broccoli adds color and keeps things balanced. If you want to go lighter, serve it over cauliflower rice or a bed of baby spinach that wilts slightly under the warm chicken.

Storage and Reheating

Leftovers keep beautifully in an airtight container in the fridge for up to four days, and the flavors deepen overnight. Reheat gently on the stovetop with a splash of chicken broth to loosen the sauce, or microwave in 30 second intervals, stirring between, to keep the chicken moist. The sauce might thicken further when cold, but a little liquid brings it right back.

Variations and Swaps

If you want a little heat, stir in a pinch of cayenne or red pepper flakes with the spices. Fresh thyme or rosemary added to the sauce brings an earthy note that pairs beautifully with the honey. Chicken thighs work wonderfully if you prefer dark meat, just cook them for 3.5 to 4 hours on low for fall apart tenderness.

  • Swap apple cider vinegar for white wine vinegar if thats what you have on hand.
  • Shred leftover chicken and pile it onto toasted rolls for quick sandwiches.
  • Double the sauce if you love extra to spoon over sides or freeze for another meal.

Recipe Questions & Answers

Can I use chicken thighs instead of breasts?

Yes, boneless chicken thighs work beautifully and often stay even juicier. Cook them for 3½ to 4 hours on low setting.

How do I store leftovers?

Store cooled chicken and sauce in an airtight container for up to 4 days. The flavors continue to develop over time.

Can I make this spicy?

Absolutely. Add ¼ teaspoon cayenne pepper or red pepper flakes to the sauce mixture before cooking for gentle heat.

What sides pair well with this?

The sauce is perfect over mashed potatoes, white rice, or roasted vegetables. Green beans or a simple salad also complement nicely.

Can I cook this on high heat?

Yes, cook on high for 2 to 2½ hours instead of 4 hours on low. The chicken should reach 165°F internally.

Why do I need to remove the chicken to thicken the sauce?

Removing the chicken prevents it from overcooking while the sauce simmers and thickens with the cornstarch slurry.
