1. Preheat your oven to 400°F (200°C). Line a baking sheet with foil or parchment paper for easy cleanup—trust me, this step saves time and stress on busy nights.
2. Pat the chicken thighs dry with paper towels. This helps the skin get crispy, which is one of my favorite parts of this dish.
3. In a small bowl, whisk together the barbecue sauce, olive oil, minced garlic, soy sauce, apple cider vinegar, smoked paprika, black pepper, salt, and crushed red pepper flakes if using. This sauce is the magic that balances sweet, tangy, and smoky flavors.
4. Place the chicken thighs skin-side up on the prepared baking sheet. Using a brush or spoon, generously coat each thigh with the barbecue sauce mixture.
5. Scatter the pineapple chunks evenly around and on top of the chicken. The pineapple will caramelize as it roasts, adding a beautiful golden color and juicy bursts of flavor.
6. Bake in the preheated oven for 35-40 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the skin is nicely browned. Halfway through cooking, baste the chicken with the pan juices and sauce to keep it moist and flavorful.
7. For extra crispiness, switch the oven to broil during the last 3-5 minutes, watching carefully to avoid burning. This step always reminds me of the balance I learned early on—too much heat can ruin a dish, but just enough can elevate it.
8. Remove from the oven and let rest for 5 minutes before serving. This allows the juices to redistribute, keeping the meat tender and juicy.

One kitchen tip I learned hosting those “Wednesday dinners” in college was to prep the sauce ahead of time. It not only saves time on a hectic evening but also lets the flavors meld together beautifully. If you’re making this for a family dinner, this step can be a real game-changer.
