Heat the oil or butter in a small saucepan over medium heat.
Add the minced garlic and sauté until fragrant and lightly golden, being careful not to burn it.
Stir in the ketchup, honey, Worcestershire sauce, hot sauce, black pepper, brown sugar, and lemon juice.
Simmer over medium-low heat for 10–15 minutes, stirring occasionally, until the sauce is smooth, thickened, and bubbling gently.
Keep the sauce warm while preparing the chicken.
Pat the chicken thighs dry.
Coat them evenly with avocado oil.
Season with salt, black pepper, and garlic powder.
Preheat the grill to medium-high heat.
Place the chicken on the hot grill and cook until nicely seared on one side.
Flip and cook the second side until the internal temperature reaches about 155°F (68°C).
Generously brush the Honey BBQ Chicken with the homemade sauce.
Flip the chicken and allow the sauce to caramelize.
Brush the opposite side with more sauce and continue grilling until the internal temperature reaches 165°F (74°C).
Remove from the grill and let the chicken rest for 5 minutes.
Serve warm with extra Honey BBQ Sauce on the side.
