Instructions

Preheat the oven to 450°F (230°C). Prepare a small bowl for the chicken rub and mix your preferred blend of spices with a pinch of salt and pepper. Brush each chicken breast lightly with olive oil, then evenly coat all sides with the rub.

Warm a large skillet over medium-high heat and add about 1 tablespoon of olive oil. Sear the chicken breasts for 4 minutes on the first side, then flip and cook 3 minutes more. Transfer the seared chicken to a lightly greased casserole dish and roast in the preheated oven for roughly 20 minutes, or until the chicken is cooked through. Cooking times will vary with the size of the breasts—use a thermometer if needed for accuracy.

While the chicken roasts, return the skillet to medium heat and add a touch more oil if needed. Sauté sliced bell peppers, chopped shallots, and a bit of onion with a sprig of rosemary for about 5 minutes, until the vegetables begin to soften. Pour in a splash of chicken broth and reduce the heat to a simmer for another 5 minutes, allowing the flavors to meld.

Stir in balsamic vinegar and season with salt and pepper. Raise the heat slightly and cook for an additional 5–6 minutes so the balsamic reduces and the sauce thickens slightly. Taste and adjust seasoning as desired.

When the chicken is done, remove it from the oven and spoon the warm bell pepper mixture over each breast. Let the dish rest a couple of minutes before serving so the juices settle and the sauce clings to the meat.

Serving Suggestions & Tips

This dish pairs nicely with a simple grain such as quinoa, couscous, or brown rice, or with roasted or steamed vegetables for a low-carb option. For extra brightness, finish with a sprinkle of fresh herbs like parsley or basil. If you prefer more caramelization, let the balsamic reduce a little longer to intensify the sauce.

To save time, you can prep the peppers and shallots in advance and store them in the refrigerator. If using thicker chicken breasts, consider gently pounding them to an even thickness so they cook uniformly. For a lighter meal, remove the skin and use boneless breasts; for juicier results, bone-in cuts can be substituted but may require longer oven time.

Leftovers keep well in an airtight container for up to three days and reheat gently over low heat or in the microwave. The flavors often deepen after a day, making this a great option for meal prep.
