This baked honey mustard chicken transforms basic chicken breasts into a restaurant-worthy dinner with minimal effort. The irresistible sauce combines three mustards with sweet honey, while caramelized onions and aromatic herbs create layers of flavor that will make this an instant family favorite.
I first made this recipe during a particularly hectic week when I needed something impressive yet effortless. The combination of mustards seemed unusual at first, but the depth of flavor converted even my mustard-skeptical teenagers into fans requesting it weekly.
Ingredients
- Boneless skinless chicken breasts or thighs: providing a lean protein base that stays juicy under the flavorful glaze
- Whole grain mustard: offering texture and rustic appeal with visible mustard seeds
- Dijon mustard: delivering that classic sharp tang that pairs perfectly with honey
- Yellow mustard: adding familiar brightness and color to the sauce
- Honey: balancing the pungent mustards with natural sweetness that caramelizes beautifully
- Olive oil: helping to create a silky sauce texture while preventing sticking
- Yellow onion: caramelized to provide a sweet aromatic foundation
- Fresh garlic: amplifying the flavor profile with its aromatic pungency
- Rosemary: infusing the dish with piney herbaceous notes that complement the honey and mustard
Step-by-Step Instructions
- Prepare the sauce:
- Whisk together the three mustards, honey, and 1 tablespoon olive oil until completely smooth. This combination creates the perfect balance of sweet and tangy that will coat the chicken beautifully. Make sure the honey is fully incorporated for even sweetness throughout.
- Caramelize the onions:
- Heat the remaining tablespoon of olive oil over medium heat and add the chopped onions. Cook them slowly for about 8 minutes until they develop a golden brown color and become sweet and soft. This process creates a flavor foundation that elevates the entire dish. Add the minced garlic during the final 30 seconds to prevent burning while still releasing its aromatics.
- Prepare the baking dish:
- Spray your baking dish with nonstick spray and spread the caramelized onion and garlic mixture evenly across the bottom. This creates a flavorful bed for the chicken to rest on while baking and prevents sticking.
- Season and arrange chicken:
- Season each piece of chicken generously with salt and pepper on both sides before placing them over the onion layer. Proper seasoning at this stage ensures flavor throughout the meat, not just from the sauce.
- Apply the mustard sauce:
- Pour the mustard mixture evenly over each piece of chicken, using a spoon to ensure complete coverage. This coating protects the chicken from drying out while baking and creates that signature tangy glaze.
- Add rosemary and bake:
- Place fresh rosemary sprigs between the chicken pieces and bake until the internal temperature reaches 165°F. The herb will infuse the sauce with its distinctive aroma during baking without overpowering the dish.

The combination of three mustards might seem excessive but trust me each brings something unique to the table. The whole grain provides texture, the Dijon brings depth, and the yellow adds familiar brightness. My family initially questioned the multiple mustards but now requests extra sauce for drizzling over rice or potatoes.
Perfect Pairings
This chicken dish pairs beautifully with simple sides that can soak up the delicious sauce. Try serving it with fluffy mashed potatoes, steamed rice, or crusty bread. For vegetables, roasted asparagus or a simple green salad balances the richness of the sauce perfectly.
Make Ahead Options
You can prepare the entire dish up to the baking point and refrigerate for up to 24 hours. Simply bring it closer to room temperature for about 20 minutes before baking and you might need to add 5 extra minutes to the cooking time. This makes it perfect for dinner parties or meal prepping on busy weeknights.
Ingredient Substitutions
If you prefer a spicier profile, try adding a tablespoon of spicy brown mustard or a teaspoon of horseradish to the sauce mixture. For a more herbaceous version, thyme works wonderfully in place of rosemary, or use a combination of both. Maple syrup can replace honey for a slightly different sweetness profile with earthy undertones.
Storage and Reheating
Leftovers keep beautifully in an airtight container in the refrigerator for up to three days. To reheat, cover with foil and warm in a 325°F oven until heated through, about 15 minutes. The sauce may thicken when chilled but will loosen again when warmed. This chicken also makes excellent cold sandwiches the next day.
Common Queries
- → Can I use chicken thighs instead of breasts?
Yes, the recipe specifically mentions you can substitute 6 boneless skinless chicken thighs for the chicken breasts. Thighs generally stay more moist and may require slightly different cooking times - cook until they reach 165°F internal temperature.
- → What can I substitute if I don't have all three mustard types?
If you're missing some of the mustards, you can adjust proportions of what you have. The key is maintaining the balance between whole grain for texture, dijon for depth, and yellow for classic flavor. In a pinch, use what you have and adjust honey levels to balance sharpness.
- → Can I prepare this dish ahead of time?
Yes, you can prepare the honey-mustard sauce and caramelize the onions a day ahead. Assemble everything in the baking dish, cover and refrigerate. When ready to cook, let it come to room temperature for 15-20 minutes before baking for best results.
- → What sides pair well with honey mustard chicken?
This chicken pairs beautifully with roasted vegetables, steamed green beans, mashed potatoes, rice pilaf, or a simple green salad. The sweet-tangy sauce works well with both starchy sides and fresh vegetables.
- → How do I know when the chicken is fully cooked?
The most reliable method is using a meat thermometer to ensure the chicken reaches 165°F in the thickest part. Without a thermometer, cut into the thickest piece - properly cooked chicken is opaque white throughout with clear (not pink) juices.
- → Can I freeze leftovers of this dish?
Yes, leftover honey mustard chicken freezes well. Cool completely, then store in airtight containers for up to 2-3 months. Thaw in the refrigerator overnight and reheat gently in the oven covered with foil to prevent drying out.
