The grilling time for steak on a gas grill depends on the thickness and desired doneness, but a general guideline is:

• For a 1 to 1.5-inch thick steak, grill about 4 minutes per side for medium-rare, totaling roughly 8 minutes.
• Thicker steaks or different doneness levels (rare, medium, well-done) will require adjusting the time accordingly.
• A common approach is to start with searing the steak over direct high heat for 1-2 minutes per side, then move to indirect medium heat for 10-20 minutes depending on steak thickness and desired doneness.
• Use an instant-read thermometer to check internal temperature: around 135°F for medium-rare, 145°F for medium, and longer for well-done.
• After grilling, rest the steak for 5-10 minutes before serving.

For example, medium-rare steak (1.5 inches thick) may take about 25 minutes total including indirect grilling and searing phases, resting about 5-10 minutes afterward.

Key time estimates for a gas grill:

• 4 minutes each side for medium-rare on direct heat (total 8 minutes)
• For thicker cuts, add 10-15 minutes indirect heat grilling
• Rest steak 5-10 minutes before slicing and serving

Using temperature as a guide rather than just time ensures the best results on a gas grill.
