Grilling bratwurst involves parboiling in beer or water first to ensure they cook through without burning. This article will teach you exactly how to cook a bratwurst on a grill so you get juicy, flavorful sausages every time.
You don’t need fancy equipment. Just a grill, some brats, and a few simple steps. Let’s get started.
How To Cook A Bratwurst On A Grill
Bratwurst are thick sausages. They need gentle heat to cook inside without charring the outside. The secret is parboiling. This step pre-cooks the sausage. Then you finish it on the grill for that smoky, crispy skin.
Follow this guide. You’ll have perfect brats in under 30 minutes.
Why Parboil Bratwurst First
Parboiling is not optional. It ensures the bratwurst cooks evenly. Without it, the outside burns before the inside is done. Parboiling also adds flavor if you use beer, onions, or spices.
- Prevents burning
- Keeps meat juicy
- Adds extra flavor
- Reduces grill time
What You Need For Parboiling
- 4–6 bratwurst links
- 1 bottle of beer (lager or ale works best)
- 1 medium onion, sliced
- 1 tablespoon butter (optional)
- 1 teaspoon salt
- 1 teaspoon black pepper
You can use water instead of beer. But beer adds a rich, malty taste. The alcohol cooks off, so it’s safe for everyone.
Step-By-Step Parboiling Process
- Place bratwurst in a large skillet or pot.
- Add beer, sliced onion, butter, salt, and pepper.
- Add enough water to cover the sausages if needed.
- Bring to a gentle simmer over medium heat.
- Do not boil. Boiling can split the casings.
- Simmer for 10–15 minutes.
- Turn the brats once halfway through.
- Remove from liquid. Pat dry with paper towels.
Patting dry is important. Wet brats won’t get a good sear on the grill.
Preparing The Grill
You can use a gas or charcoal grill. Both work fine. The key is medium heat.
- Gas grill: Preheat to medium (around 350–400°F).
- Charcoal grill: Light coals and let them ash over. Spread evenly.
- Oil the grates lightly to prevent sticking.
Clean grates are crucial. Scrub them with a wire brush before heating.
Grilling The Bratwurst
- Place parboiled brats on the grill.
- Cook for 4–5 minutes per side.
- Turn every 2–3 minutes for even browning.
- Total grill time: 10–12 minutes.
- Use tongs, not a fork. Piercing releases juices.
Look for a deep golden-brown color. The skin should be crisp but not blackened.
Checking Doneness
Bratwurst are done when the internal temperature reaches 160°F. Use an instant-read thermometer. Insert it into the end of the sausage.
If you don’t have a thermometer, cut one open. The meat should be white throughout with no pink. The juices should run clear.
Resting The Brats
Let the brats rest for 3–5 minutes off the grill. This lets the juices redistribute. If you cut them immediately, they’ll dry out.
Resting also makes them easier to handle for serving.
Serving Suggestions For Grilled Bratwurst
Bratwurst are versatile. Serve them in a bun or on a plate. Here are classic toppings and sides.
Classic Toppings
- Mustard (yellow, spicy brown, or Dijon)
- Grilled onions (use the onions from parboiling)
- Sauerkraut
- Relish
- Ketchup (optional, but traditionalists skip it)
Bun Options
- Soft hoagie rolls
- Pretzel buns
- Brioche buns
Toast the buns on the grill for 30 seconds. This adds texture and prevents sogginess.
Side Dishes
- German potato salad
- Coleslaw
- Grilled corn on the cob
- Baked beans
- Beer (of course)
Common Mistakes To Avoid
Even experienced grillers make errors. Here are the biggest ones.
Skipping The Parboil
Some people think grilling raw brats is fine. It’s not. The outside burns, the inside stays raw. Parboiling is non-negotiable.
Using High Heat
High heat chars the casing before the meat cooks. Medium heat gives you a gentle sear.
Poking The Sausage
Never prick bratwurst with a fork. The juices escape. Use tongs to turn them.
Overcooking
Bratwurst dry out fast. Once they hit 160°F, remove them from the grill. Keep them warm in a foil packet if needed.
Variations On The Basic Method
You can customize the parboiling liquid and grilling technique.
Beer Alternatives
- Chicken broth
- Apple cider
- White wine
- Water with garlic and bay leaves
Spice Additions
- Caraway seeds
- Bay leaves
- Garlic cloves
- Red pepper flakes
Grilling Variations
- Smoke the brats with wood chips for extra flavor
- Glaze with barbecue sauce in the last 2 minutes
- Grill with sliced bell peppers and onions
Frequently Asked Questions
Can I Grill Bratwurst Without Parboiling?
Yes, but it’s risky. You need to use very low heat and cook them slowly. Even then, they may not cook evenly. Parboiling is safer and faster.
How Long Do I Grill Bratwurst After Boiling?
About 10–12 minutes total. Turn every 2–3 minutes for even browning. Check internal temperature to be sure.
What Beer Is Best For Bratwurst?
A light lager or ale works well. Avoid dark, heavy beers. They can make the brats bitter. Popular choices include Pilsner, Hefeweizen, or a simple domestic lager.
Can I Use Frozen Bratwurst?
Yes, but thaw them first. Grilling frozen brats leads to uneven cooking. Thaw in the fridge overnight or in cold water for 30 minutes.
How Do I Keep Bratwurst Warm For A Party?
After grilling, place them in a slow cooker with the leftover parboiling liquid. Set on warm. They’ll stay moist for hours.
Final Tips For Perfect Grilled Bratwurst
Practice makes perfect. Here are a few last pointers.
- Always preheat your grill fully.
- Don’t overcrowd the grill. Leave space between brats.
- Use a meat thermometer. It’s the only way to be sure.
- Serve immediately after resting.
- Pair with cold beer for the full experience.
