1-Getting started with honey mustard baked chicken begins with simple steps that anyone can follow, even if you’re new to cooking: First, preheat your oven to 375°F to make sure it’s ready for even baking. This temperature helps the chicken cook through without drying out, keeping it juicy and full of flavor.

2-Next, whisk together the mustards, honey, and 1 tablespoon of olive oil in a bowl until smooth: This mixture forms the heart of the dish, giving it that signature sweet and tangy glaze. In a pan, sauté the chopped yellow onion in the remaining 1 tablespoon of olive oil over medium heat for about 8 minutes until it turns golden brown, then add the minced garlic and cook for another 30 seconds to release its aroma.

3-Spread the onion and garlic mixture evenly in a 13 by 9-inch baking dish to create a flavorful base: Season the 4 to 5 chicken breasts or 6 chicken thighs with salt and pepper, place them on top of the onion layer, and coat them generously with the honey mustard sauce. Tuck 4 small sprigs of rosemary between the pieces for an extra herb note that enhances the overall taste.

4-Baking and Serving Tips: Bake the dish for 25 to 30 minutes, checking that the internal temperature of the chicken reaches 165°F for safe eating. If the sauce starts to brown too quickly, cover the dish with foil toward the end to prevent burning. Once done, let the chicken rest for 5 minutes before serving, and don’t forget to spoon the sauce over each piece for maximum flavor.
