How Long to Grill Burgers at 400°F
01 The Short Answer
At 400°F on a gas grill, a standard 3/4-inch burger patty takes 4 to 5 minutes per side for a total of 8 to 10 minutes. That gets you to approximately 160°F internal temperature, which is the USDA-recommended safe minimum for all ground beef.
The full picture is more nuanced. Patty thickness, fat content, starting temperature, and lid position all affect actual cook time. This guide provides specific timing for every thickness, explains what temperature to grill burgers for the best results, and covers the technique details that make the biggest practical difference — including why you should never press the burger and when to add the cheese.
For the same timing principles applied to steak, see our complete guide on how long to cook steak on grill.
At 400°F, the exterior browns and develops good grill marks before the interior overcooks. Higher temperatures (450–500°F) work for thinner smash-style patties but require very tight timing on standard patties. Lower temperatures produce pale, steamed-looking burgers without the crust that makes grilling worthwhile.
02 How Long to Grill Burgers at 400 — By Thickness
These times are based on a preheated gas grill at 400°F with the lid closed. Times represent cooking per side. Always verify doneness with a meat thermometer — the patty must reach 160°F for safe consumption.
| Patty Thickness | Patty Weight | First Side | Second Side | Total Time | Target Temp |
|---|---|---|---|---|---|
| 1/4 inch (thin) | 2–3 oz | 2 min | 1–2 min | 3–4 min | 160°F |
| 1/2 inch | 3–4 oz | 3–4 min | 2–3 min | 5–7 min | 160°F |
| 3/4 inch (standard) | 4–5 oz | 4–5 min | 4–5 min | 8–10 min | 160°F |
| 1 inch (thick) | 6–8 oz | 5–6 min | 5–6 min | 10–12 min | 160°F |
| 1.5 inch+ (smash) | 8–10 oz | 6–7 min | 6–7 min | 12–14 min | 160°F |
03 Burger Internal Temperature by Doneness
Unlike whole cuts of beef where rare and medium rare are safe, ground beef must always reach 160°F. The grinding process incorporates surface bacteria throughout the patty, which means there is no safe rare option with standard ground beef.

04 How to Grill Hamburgers on a Gas Grill at 400°F
The process of how to grill hamburgers on a gas grill is straightforward, but a few technique details make a significant difference in the result.
Step-by-Step Process
Turn the gas grill to medium-high and let it preheat with the lid closed for 10 to 15 minutes. Most gas grills reach 400°F in this window. Use the built-in thermometer to confirm the temperature before adding the patties. A cold grill causes the burger to stick and cook unevenly.
Use tongs to wipe a folded paper towel dipped in neutral oil over the grill grates just before placing the patties. Do not brush oil directly onto the patties — it causes flare-ups and can dry out the surface. Oiled grates provide non-stick release without adding unnecessary fat.
Place the patties on the grill and do not touch them for the full first side cooking time (4 to 5 minutes for 3/4-inch). Moving or lifting the patty before the crust has set causes tearing and uneven browning. The burger will release naturally from the grates when the crust is properly formed.
Flip each patty once using a thin metal spatula. After flipping, add the cheese slice in the last 60 to 90 seconds of cooking and close the lid to melt it. Check the internal temperature at the thickest part of the patty — pull at 160°F and rest for 2 minutes before assembling.
05 The Best Patty for Grilling at 400°F
The fat ratio, weight, and thickness of your patty directly affect how it behaves at 400°F. Here is a quick reference for the most common options.
| Fat Ratio | Best For | At 400°F Result | Note |
|---|---|---|---|
| 90/10 (lean) | Health-focused | Drier, can stick to grates | Add a little oil before grilling |
| 85/15 | Everyday grill | Good crust, moderate juiciness | Reliable choice |
| 80/20 ★ | Best grill result | Great crust, juicy at 160°F | Most popular for backyard grilling |
| 75/25 (fatty) | Rich flavor | Heavy flare-ups, very juicy | Monitor closely for flare-ups |
400°F is the practical standard for standard patties. If you are making thin smash-style patties (under 1/4 inch), go up to 450–500°F for maximum crust. If you are cooking thick stuffed burgers (over 1.5 inches), go down to 350–375°F and use a two-zone setup to avoid charring the outside before the center reaches 160°F.
06 Key Tips for Consistent Burgers at 400°F
Thermometer Always
The only reliable way to confirm 160°F. A $15 instant-read thermometer eliminates guesswork entirely.
Preheat 10–15 Minutes
A properly preheated grill gives you grill marks and crust formation from the first second of contact.
Flip Only Once
One flip at the halfway point. Multiple flips interrupt crust formation and extend total cook time.
Rest 2 Minutes
A short rest after pulling from the grill lets the juices settle. Assembling immediately sends them running out.
Keep Patties Cold
Cold patties hold their shape better on the grill than warm ones. Work quickly when forming patties and refrigerate until ready.
Toast the Bun
Place buns cut-side down on the grill for 30 to 60 seconds while the patty rests. A toasted bun holds up to the juices without going soggy.
