Short answer: Grill thin patties (½" / 12 mm) about 2–3 min per side on high heat for medium. For ¾" patties grill ~3–4 min per side. For 1"–1½" patties expect 4–6 min per side. Always verify with an instant-read thermometer — target internal temps are included below.
Quick reference — Grill times & target internal temperatures
| Patty thickness | Doneness | Target internal temp | Approx. grill time (per side) |
|---|---|---|---|
| 1/2 inch (12 mm) | Medium-rare | 130–135°F (54–57°C) | 1.5–2.5 min |
| 1/2 inch | Medium | 140–145°F (60–63°C) | 2–3 min |
| 3/4 inch (18 mm) | Medium | 140–145°F (60–63°C) | 3–4 min |
| 1 inch (25 mm) | Medium-well | 150–155°F (66–68°C) | 4–6 min |
| 1–1.5 inch | Well-done | 160°F (71°C) | 6+ min |
Why time varies (and why thermometer beats the clock)
Grill time depends on: patty thickness, meat fat content, grill surface temperature, whether you cook covered, ambient temperature, and whether patties are chilled. The only reliable method is measuring internal temperature with an instant-read thermometer.
Step-by-step grilling method (fast, repeatable)
- Preheat & clean: Preheat your grill to high (450–500°F/230–260°C) and clean the grates.
- Form patties: Make even patties, slightly wider than the bun. For best sear use 80/20 or 85/15 grind.
- Season: Salt just before grilling to avoid drawing moisture out. Pepper to taste.
- Sear: Place patties on the hottest part of the grill. Don’t press them — that squeezes juices out.
- Flip once: Flip once halfway through the target time; avoid repeated flipping.
- Check temp: Insert instant-read thermometer through the side into the center; follow target temps below.
- Rest: Rest patties 3–5 minutes before serving to let juices redistribute.
Safety & target internal temperatures
USDA recommends cooking ground beef to 160°F (71°C) to destroy pathogens. If you prefer lower temps (for medium or medium-rare), understand there is a slightly higher risk if meat isn't fresh or handled carefully.
Chef tips for juicier burgers
Grill temperature guide
Preheat grill zones: High searing zone 450–550°F (230–290°C). Medium zone 375–425°F (190–220°C). Use a grill surface thermometer or infrared thermometer for accuracy.
Common mistakes
- Pressing patties while cooking (loses juices).
- Cooking straight from frozen — thaw first for consistent timing.
- Underseasoning — salt helps flavor and crust formation.

Jump to FAQFrequently asked questions
Can I grill burgers from frozen?
Yes, but expect longer cook times and uneven doneness. For best results thaw and pat dry before cooking.
How thick should homemade patties be?
For even cooking, 3/4" to 1" is a good home range. Very thin patties cook extremely fast but can dry out.
