Air Fryer Bratwurst: German Sausage Without a Grill

Print

Bratwurst cooked on a grill is wonderful. But grilling isn’t always an option — it’s winter, it’s raining, you don’t own a grill, or you just want dinner in 15 minutes. The air fryer offers a quick, easy, and delicious alternative, making air fryer brats a perfect solution for any season or situation.

What You Need (Serves 4)

• 4–6 bratwurst links (fresh or fully cooked/smoked)
• Optional: 1 tablespoon olive oil or butter for brushing
• Brat buns or hoagie rolls

Classic toppings:

• Sauerkraut (warmed)
• Spicy brown mustard or whole grain mustard
• Caramelized onions
• Sliced peppers

Fresh vs. Pre-Cooked Bratwurst

This distinction matters for cooking time:

• Fresh bratwurst (raw, uncured) — the most common type found at the butcher or meat counter. Pink and soft when raw. Cook to internal temperature of 160°F.
• Fully cooked/smoked bratwurst — already cooked, just needs reheating. Cook to 145°F, or until heated through and the casing blisters.

Check the package — it will say “fully cooked” if applicable. When in doubt, use a thermometer.

Cooking Fresh Bratwurst in the Air Fryer

Do not score or prick the bratwurst before cooking. Pricking lets the fat (and therefore the flavor and moisture) escape. Keep the casing intact.

Preheat your air fryer to 360°F for 3 minutes. Place the brats in a single layer in the basket — they can be close together but should have some air space between them.

Cook for 15–17 minutes, turning every 5 minutes for even browning on all sides. The casing should be deep brown and slightly crispy, and the internal temperature should reach 160°F.

Don’t rush with higher heat — fresh bratwurst at too high a temperature will have the casing split and the fat render out before the interior is cooked through. 360°F is the sweet spot.

Cooking Pre-Cooked/Smoked Bratwurst

Pre-cooked brats are faster. Cook at 380°F for 9–11 minutes, turning once. You’re looking for blistered, browned skin and an internal temperature of 145°F.

Caramelized Onions and Peppers (Stovetop)

While the brats cook, heat 1 tablespoon of butter in a skillet over medium heat. Add 1 sliced onion and 1 sliced bell pepper. Season with salt and a pinch of sugar. Cook for 12–15 minutes, stirring occasionally, until soft and golden. Pile these on the brats right before serving.

This stovetop side takes about the same time as the brats — run them in parallel and everything finishes together.

Serving the Brats

Classic German-American style: in a soft brat bun with spicy brown mustard and sauerkraut. Serve with potato salad or German potato wedges, coleslaw, or just chips and a cold beer.

For an Oktoberfest plate, skip the bun and serve whole with sauerkraut, whole grain mustard, and a side of warm soft pretzels.

Tips for the Best Air Fryer Brats

• Don’t prick. Keep the casing whole for maximum juiciness.
• Lower temperature for fresh brats. 360°F gives the interior time to cook through while the casing browns evenly.
• Turn them. Unlike chicken, sausages benefit from being turned every 5 minutes to brown all sides.
• Rest before serving. 3–5 minutes of resting after cooking lets the juices settle. Cutting into a brat immediately loses the juice.
• Warm the buns in the air fryer. 30 seconds at 350°F gives you a warm, slightly toasted bun that doesn’t go soggy under the toppings.

Frequently Asked Questions

Can I boil the bratwurst in beer first and then air fry?
Yes — this is a classic method. Simmer the brats in beer and onions for 10 minutes, then air fry at 390°F for 5–6 minutes to char and crisp the casing. It adds flavor but adds time and a pot to clean.

My brat casing split. What happened?
The temperature was too high, or the brats went from refrigerator-cold directly into a screaming hot air fryer. Let them come closer to room temperature (15–20 minutes on the counter) before cooking, and use 360°F for fresh brats.

Can I cook frozen brats?
Yes, but thaw them first for best results. Frozen-to-air-fryer works but the exterior browns before the interior cooks through. Thaw in cold water for 20–30 minutes if you’re in a hurry.

Are there different types of bratwurst?
Yes — Johnsonville is the most widely known American brand. German butchers make dozens of regional varieties. For air frying, any fresh pork or pork-veal brat works well. Chicken bratwurst is leaner and cooks faster (about 12–14 minutes at 360°F).

Can I cook brats and peppers together in the air fryer?
You can put sliced peppers and onions in the basket with the brats, but the vegetables need 400°F while brats do better at 360°F. Better to cook them separately or on the stovetop simultaneously.
