Preheat grill to medium-high heat (about 375–450°F / 190–230°C)
Use 80/20 ground beef for best flavor and juiciness
Form patties gently into even thickness (about 1/2–3/4 inch)
Season patties with salt and pepper just before grilling
Lightly oil the grill grates to prevent sticking
Place patties on the grill and close the lid
Grill without pressing; flip once at about halfway through cooking
Cook to desired doneness:
125–130°F / 52–54°C for rare
135–140°F / 57–60°C for medium-rare
145°F / 63°C for medium
155–160°F / 68–71°C for medium-well
165°F / 74°C for well-done
Remove patties when they reach target internal temperature (they’ll rise slightly)
Rest patties 3–5 minutes before assembling
Toast buns briefly on the grill cut-side down until lightly browned
Assemble with preferred toppings and condiments
Optional: add cheese during the last 1–2 minutes of grilling and close the lid to melt
