  • Red and yellow bell peppers: chopped colorful sweetness balances savory elements
  • Mushrooms: sliced add earthiness and a meaty texture fresh and firm varieties work best
  • Olive oil: for coating and roasting, opt for extra virgin for richer flavor
  • Salt and black pepper: simple seasoning to enhance natural tastes
  • For the garlic sauce: key components for the sauce that tie the dish together
  • Glutenfree tamari: rich umami flavor and safe for gluten sensitivity
  • Glutenfree Worcestershire sauce: adds complexity and mild acidity check for certified glutenfree labels
  • Apple cider vinegar: brings brightness and slight tang to balance richness
  • Minced fresh garlic: the heart of the sauce offering aromatic warmth
  • Smoked paprika: adds smoky depth, enhancing the garlic notes
  • Dried oregano: herbaceous undertones for balance
  • Onion powder: subtle sweetness and savoriness
  • Crushed red pepper flakes (optional): a gentle heat for those who enjoy a kick

Instructions

Preheat the Oven and Prepare Chicken:
Preheat your oven to 400 degrees Fahrenheit or 200 degrees Celsius. Cut the boneless, skinless chicken breasts into chunks of similar size to ensure they cook evenly. Set these aside.
Combine Vegetables and Chicken:
In a large bowl, toss together the chicken chunks with broccoli florets, the chopped red and yellow bell peppers, and sliced mushrooms. Drizzle with two tablespoons of olive oil, then sprinkle salt and black pepper over the mixture. Toss everything thoroughly so each piece is coated well with oil and seasoning.
Prepare the Garlic Sauce:
In a separate bowl, whisk together the glutenfree tamari, glutenfree Worcestershire sauce, apple cider vinegar, olive oil, minced garlic, smoked paprika, dried oregano, onion powder, and if using, crushed red pepper flakes. Make sure the sauce is smooth and well combined for an even layer of flavor.
Combine and Arrange for Baking:
Pour the garlic sauce over the chicken and vegetable mixture in the bowl. Toss gently to coat everything evenly with the sauce. Spread the coated mixture evenly in a single layer on a large baking dish or sheet pan to allow proper roasting and caramelization.
Bake to Perfection:
Place the baking dish in the preheated oven. Bake uncovered for about 25 to 30 minutes. Check that the chicken reaches an internal temperature of 165 degrees Fahrenheit or 74 degrees Celsius using a meat thermometer to guarantee safe and tender results. The vegetables should be tender yet retain some crispness. For added caramelization and a delightful crisp edge, broil the dish under high heat for the final two to three minutes.

My favorite ingredient has to be the smoked paprika in the garlic sauce. It brings a subtle smoky richness that turns a simple bake into something special. One Sunday, this dish became the centerpiece of a big family gettogether, and every guest asked for the recipe, proving how a little spice can make all the difference.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to three days. When reheating, use a moderate oven temperature around 350 degrees Fahrenheit for ten to fifteen minutes to keep the chicken juicy and the vegetables from becoming mushy instead of using a microwave.

Ingredient Substitutions

If mushrooms are not your favorite, zucchini sliced into halfmoons offers a fresh, slightly sweet alternative that pairs beautifully with the garlic sauce. For those preferring a vegetarian route, firm tofu cubes make a wonderful protein replacement, soaking up the savory sauce while keeping a satisfying texture. Instead of crushed red pepper flakes you can add a drizzle of glutenfree sriracha sauce for a more nuanced heat with a touch of tang.

Serving Suggestions

A sprinkle of freshly chopped parsley or basil right before serving brightens the dish in both color and flavor. Pair with brown rice or quinoa for a complete meal that is both filling and nutritious. Feel free to swap in seasonal vegetables like asparagus in spring or roasted root veggies in fall to tailor this dish to the seasons.
