How Long To Cook Brats On The Grill | The Real Grilling

Grill fresh bratwurst over medium-low heat for 15 to 22 minutes, turning every 3–4 minutes, until the internal temperature reaches 160°F.

You’ve seen it at every summer cookout — brats tossed onto a hot grill, rolled a few times until the casings char, and then declared ready. But a good-looking exterior can hide an undercooked center, especially with ground-meat sausages that need a precise internal temperature to be safe to eat.

Cooking brats on the grill the right way means knowing your starting point. Fresh raw brats take about 15 to 22 minutes over medium-low heat, while pre-cooked links heat through in roughly 8 to 10 minutes. The golden rule for all of them is to hit an internal temperature of 160°F as measured by an instant-read thermometer.

Fresh Brat Cooking Times

If you’re working with raw, uncooked bratwurst from the butcher or grocery store, plan for a longer grill session. Most recipes suggest placing them over medium-low heat — around 350°F on a gas grill — and turning every 3 to 4 minutes with tongs. The total time usually falls between 18 and 22 minutes.

Parboiling is a popular shortcut that cuts grill time. Simmer the raw brats in beer or water for about 10 minutes, then transfer them to the grill. Parboiled brats only need 10 to 12 minutes over medium heat to develop a crisp casing and reach the same 160°F target.

Pre-cooked brats, often sold vacuum-sealed, are already fully cooked. Your job is simply to rewarm them and add a bit of char. A quick 8 to 10 minutes on a medium-high grill is enough, but you should still confirm the internal temperature is at least 160°F.

Why The Simple Timer Falls Short

Several variables can shift the perfect cooking time by several minutes. Relying on a timer alone ignores factors that affect heat transfer inside the sausage.

• Brat type and moisture content: Fresh raw brats contain more moisture than pre-cooked, so they take longer to heat through. Extra-lean blends may cook faster but risk drying out.
• Grill temperature consistency: Gas grills hold a steadier temperature than charcoal, which can spike and dip. A lid-down approach stabilizes the heat and reduces flare-ups.
• Brat diameter: Thicker sausages need more time in the center. A brat that’s an inch and a half across may need an extra 5 minutes beyond standard recommendations.
• Use of a lid vs. open grilling: Keeping the lid on creates an oven-like environment that cooks the brat evenly from all sides, shortening overall time and preventing burnt exteriors.
• Personal doneness preferences: Some grillers like a deep char, others prefer a lighter color. Adjust the final minute over direct heat for extra browning, but never at the expense of reaching 160°F.

The bottom line here is that the thermometer, not the clock, should be your final authority. Times are useful starting points, but only a probe tells you when the inside is truly safe.

Temperature Rules and the Two-Zone Method

The USDA recommends 160°F as the safe minimum internal temperature for all ground meats, including bratwurst. Reaching that temperature without burning the outside requires a two-zone setup: an indirect-heat side for gentle cooking and a direct-heat side for a finishing sear. Ddrbbqsupply’s guide on grilling fresh brats time recommends this approach for consistent results.

Set your grill to medium-low and place the brats on the cooler side. Cook with the lid closed for most of the time, turning every few minutes. When the internal temp reaches about 155°F, move them directly over the burners or coals for the last minute or two to crisp the casing.

The following table compares common preparation methods and their approximate grilling times on a gas grill set to medium-low heat.

Whichever method you choose, the only number that truly matters is 160°F on an instant-read thermometer inserted into the thickest part of the sausage without touching the casing.

How To Grill Brats Step by Step

A simple step-by-step sequence removes the guesswork. Follow these actions in order, and you’ll get consistently juicy, safe brats.

1. Preheat your grill: Set up a two-zone fire with one side at medium-low (around 350°F) and the other side at medium-high. Leave the lid closed for 10–15 minutes to stabilize the temperature.
2. Cook indirectly: Place the brats on the cooler side, cover the grill, and let them cook for 12–15 minutes. Turn every 3–4 minutes with tongs to promote even browning.
3. Check the temperature early: After 12 minutes, start probing the thickest part of a brat. Once it reads 155°F, you’re close to the finish line.
4. Sear over direct heat: Move the brats to the hot side of the grill for 1–2 minutes per side to deepen the color and crisp the casing. The internal temp should climb to 160°F.
5. Rest or keep warm: Transfer the brats to a clean plate and let them rest for 3–5 minutes. Alternatively, drop them into a warm beer-and-onion mixture (a Brat Bath) to hold until serving.

Avoid piercing the brats with a fork — that lets juices escape. Tongs are all you need. If you’re cooking a large batch, keep finished brats on the indirect-heat side of the grill or in a covered dish to stay above 140°F.

Brat Bath and Serving Tips

Once your brats hit 160°F, keeping them warm and moist for a crowd is the next challenge. A Brat Bath — a mixture of simmered beer, butter, and sliced onions — is a classic Wisconsin trick. Fergusonfarms explains in its grill brats 20 minutes article that the bath maintains temperature and adds flavor without drying out the sausages.

To make a Brat Bath, combine one can of beer, a tablespoon of butter, and a sliced onion in a disposable aluminum pan or small saucepan. Simmer for 5 minutes, then add the cooked brats. Keep the pan on the coolest part of the grill or on a low burner until you’re ready to serve. The brats will stay moist and pick up a subtle onion-and-beer note.

Serve the brats on sturdy hoagie rolls with mustard, sauerkraut, or your favorite toppings. The following quick-reference table lists the key internal temperatures to remember.

The Brat Bath is optional, but it’s a time-tested way to serve juicy brats even if your grill timing isn’t perfect. Just remember that the bath is for holding, not cooking — the 160°F milestone must be reached on the grill first.

The Bottom Line

Grilling brats well comes down to two things: using a two-zone heat setup and trusting an instant-read thermometer over a timer. Fresh raw brats need 15 to 22 minutes on medium-low, pre-cooked need about 8 to 10 minutes, and parboiled links cook through in roughly 10 to 12 minutes. In every case, 160°F is your safety marker.

Your meat thermometer is the real guide here — for a safe, juicy brat, trust 160°F, not a timer. If you’re cooking for a crowd, a warm beer bath on the side of the grill keeps everything ready without overcooking.
