Pour this 1 mixture over raw chicken breasts into a slow cooker for a weeknight dinner that hits different every single time

This slow cooker honey mustard chicken is the kind of weeknight dinner you can set up in minutes and let quietly transform while you do everything else. The entire flavor comes from one simple mixture—honey, Dijon mustard, whole grain mustard, apple cider vinegar, and garlic—poured straight over raw chicken breasts in the slow cooker. Honey mustard as a combination has roots in classic European mustard sauces, but here it gets the Midwestern, busy-home-cook treatment: pantry staples, minimal prep, and a deeply comforting result that tastes a little different every time depending on your honey, mustard brands, and how long you let it simmer.

Serve the chicken sliced or shredded with plenty of the honey mustard sauce spooned over the top. It’s especially good over steamed rice, buttered egg noodles, or mashed potatoes to catch all the juices. A crisp green salad with a simple vinaigrette or roasted vegetables (broccoli, carrots, or Brussels sprouts) balances the sweetness nicely. If you like a bread option, warm crusty rolls or a baguette make excellent tools for mopping up the extra sauce.
