This Genius Hack Prevents BBQ Sauce From Sticking to the Grill
Anyone who has grilled with barbecue sauce knows the joy it adds to meat—and the frustration it can leave behind. A perfect rack of ribs or chicken thighs can quickly turn into a mess when the sauce glues itself to the grates.
Fortunately, the problem has a simple fix.

The sticky problem is sugar. Most barbecue sauces contain a large amount of it, and sugar reacts strongly to heat. At moderate temperatures, it caramelizes and creates a rich flavor with a glossy finish. But as the heat continues, it darkens, hardens, and eventually crystallizes.
Once it reaches that stage, it clings to metal grates and makes the food difficult to release. Sauces with higher sugar levels, like Sweet Baby Ray’s with 16 grams per two-tablespoon serving, are especially prone to this reaction.
So, What Can You Do About It?
The easiest way to avoid the sticking is to control the timing. Instead of brushing it on at the start, wait until the meat is almost finished. This allows the sauce to warm, caramelize slightly, and thicken into a glaze without ever reaching the point where it burns or bonds to the grates.
Pitmaster Shannon Snell suggests applying sauce in the last 20 to 25 minutes of cooking. That window is long enough to give the meat color and flavor, but short enough to prevent adhesion. On the other hand, Christie Vanover, owner of Girls Can Grill, suggests a slightly shorter timeframe of 10 to 15 minutes, which works especially well if your grill runs hot. Both approaches keep the sauce where it belongs—on the food instead of stuck to the grill.

Vanover also recommends moving food away from direct flames once the sauce is on. Open flames push the sugars to burn too quickly, which leaves behind charred spots and clingy residue.
Her solution is to set up a two-zone grill. Keep one side hot for searing and the other cooler for finishing. When you’re ready to add sauce, shift the meat to the cooler zone. This lets the glaze firm up slowly without scorching or sticking to the grates.
What Happens If You Ignore These Steps
Grillers usually learn these lessons the hard way. One moment the chicken looks perfect, the next the skin stays glued to the grates in a crust of burned sugar. Meanwhile, ribs brushed too soon can come off the grill with patches of sauce turned bitter and black. And if you leave the grates dirty, the old residue gradually re-heats and locks stubbornly onto whatever you cook next.
