How Long Do You Cook a Burger For | Times by Doneness & Method

A standard 8 oz beef burger on a 400°F grill needs 6–7 minutes total for medium-rare, 7–8 for medium, and 10+ for well-done, but a thermometer reading 160°F is the only guarantee of safety with store-bought ground beef.

That sizzle hitting the grate sounds like dinner is close — and it is, but guessing by color alone is how dry, overcooked, or underdone burgers happen. The real answer depends on thickness, heat source, and your preferred doneness, plus a hard safety number that matters with any supermarket ground beef. Here’s exactly how long each method takes, with the temps that tell you it’s right.

Does the Doneness Really Change the Time?

Yes, and by only a few minutes. On a preheated grill at 375–400°F, an 8 oz patty goes from rare to medium-rare in roughly two more minutes, and from medium to well-done in three more. The difference between medium-rare and medium is a single flip cycle — about two minutes of extra heat.

That narrow window means timing by the clock alone risks landing a slice past where you wanted it. A digital thermometer fixes that: pull the burger when the internal temp reads 5°F below your target, because carryover cooking will lift it another 5–10°F during rest.

Burger Cooking Times by Method

Every heat source transfers energy differently, so times vary. The chart below covers the most common methods with verified times for an 8 oz patty cooked to 160°F internal (the USDA safe endpoint for store-bought ground beef). Thinner or thicker patties shift the numbers proportionally — a 4 oz patty cooks about 30% faster, while a 12 oz patty needs roughly 25% more time.

How to Grill a Burger on an Open Flame

Grilling gives the best flavor and the widest doneness range, but requires attention to temp and flip timing. Follow these steps for consistent results every time.

Step-by-Step Grilling

1. Preheat the grill to 375–400°F. A hot grate sears the surface and locks in juices. Let it stabilize for 10 minutes with the lid closed.
2. Season both sides evenly. Salt and pepper is all you need — anything else goes on after cooking to avoid burning.
3. Cook the first side for 1–3 minutes. Flip when a browned crust forms. Don’t press the patty with a spatula; that squeezes out the juices that keep it tender.
4. Flip and cook the second side for another 1–3 minutes. Flip 3–4 times total for even interior cooking. Each flip transfers heat more uniformly than one long sear per side.
5. Check internal temperature with a digital thermometer. Insert the probe into the thickest part of the patty — center for even-thickness patties, offset for hand-formed ones. Pull at 5°F below your target (e.g., 155°F for well-done at 160°F).
6. Rest for 5 minutes under loose foil. This lets juices redistribute and the internal temp climb 5–10°F. Skipping the rest means drier meat.

Common Grilling Mistakes

Pressing the patty is the number one error — it forces the fat and moisture onto the fire, causing flare-ups and a dry burger. Flipping too early tears the crust and prevents good sear. Overcrowding the grate drops the grill temp and steams the patties instead of searing them. Leave at least an inch between burgers.

Doneness Temperatures and What They Look Like

Temperature is the only reliable guide, but visual cues help when a thermometer isn’t handy. The chart below maps internal temp to appearance and feel.

USDA guidelines require 160°F for store-bought ground beef because grinding redistributes surface bacteria throughout the meat. For custom-ground beef from a trusted source, lower temps down to 125°F are safe provided the meat was handled and ground fresh. The 160°F rule is the universal safety floor for anyone without a documented cold chain from farm to kitchen.

What About Carryover Cooking?

Carryover is the heat that keeps rising inside the meat after it leaves the heat source. A thick 8 oz patty will rise 5–10°F during the 5-minute rest. If you remove the burger exactly at 160°F, it may climb to 168°F by the time you bite in — landing well past well-done even if you wanted medium.

The fix: pull the patty 5°F below your target. For a medium burger, remove at 135–140°F and rest. The carryover lift will bring it into the 140–145°F zone. For well-done, pull at 150–155°F and let it ride up to 160°F.

Getting It Right Every Time: A Checklist

Start with the right thickness. Patties ½-inch to ¾-inch thick cook evenly and fit standard buns. Season right before cooking, not hours ahead — salt draws moisture out, and a dry patty is a tough patty. Use the same thermometer for every batch to learn its quirks and your grill or skillet’s hotspots.

Rest every burger for 5 minutes regardless of doneness. That short pause makes the difference between a burger that leaks juices onto the plate and one that keeps them inside the bun where they belong.
