Mix honey, minced garlic, grated ginger, soy sauce, olive oil, and lemon juice in a bowl. Stir everything together until smooth and the honey dissolves into the liquid. This is your marinade for the honey garlic chicken thighs grill.
Pat your chicken thighs dry with paper towels, then season both sides with salt, pepper, and smoked paprika. The dry rub helps the glaze stick better once you add it. Don't skip this step — trust me on this.
Place thighs in a shallow dish and pour the marinade over them, making sure every piece gets coated. Let them sit for at least 10 minutes while you get your grill ready. If you've got more time, 20 minutes is even better.
Heat your grill to medium-high heat and lightly oil the grates so nothing sticks. You want the grill hot enough that you hear a sizzle the second the chicken hits it. Don't crank it to maximum — that'll char the outside before the inside cooks.
Place chicken thighs on the grill skin-side down and let them cook without moving for 7 to 8 minutes. You'll see the edges start turning golden and juices pooling — that's when you know it's ready to flip. Mine always sticks a little to the pan and that's fine; just be gentle with your tongs.
Flip the thighs and brush them generously with any remaining marinade from the bowl. Cook for another 8 to 10 minutes until the internal temperature reaches 165°F when checked with a meat thermometer at the thickest part. The glaze will get all bubbly and caramelized — that's exactly what you want.
Remove the thighs from the grill and let them rest for 3 to 5 minutes before serving. This keeps all the juices inside instead of running all over your plate. I like squeezing a tiny bit of fresh lemon juice right before eating — it brightens everything up.
