Juicy bratwurst cooked in the air fryer with an evenly browned exterior and satisfying snap. Ready in about 15 minutes with no pre-boiling required.
- Prep Time: 3 minutes
- Cook Time: 15 minutes
- Total Time: 18 minutes
- Yield: 4-6 servings 1x
- Category: Dinner
- Method: Air Fryer
- Cuisine: German
Ingredients
- 4–6 bratwurst links (fresh, pre-cooked, or frozen)
- Cooking spray or light oil (optional)
- Brat buns or hoagie rolls
- Toppings: sauteed onions and peppers, mustard, sauerkraut, or relish (optional)
Instructions
- Preheat the air fryer to 370°F (188°C) for 3 minutes. Lightly spray the basket with cooking spray if desired. Do not pierce the brat casings.
- Place brats in a single layer in the basket without stacking. In a standard 5–6 quart basket, 4–6 links fit comfortably side by side.
- Cook fresh brats at 370°F for 12–15 minutes, flipping at the halfway point (6–7 minutes). For pre-cooked brats, cook 8–10 minutes flipping at 4–5 minutes. For frozen raw brats, cook at 350°F for 20–22 minutes flipping at 10 minutes.
- Use an instant-read thermometer to confirm doneness: fresh brats must reach 160°F (71°C); pre-cooked brats must reach 165°F (74°C).
- Remove brats from the air fryer and rest on a plate for 3–5 minutes before serving. Toast buns in the air fryer at 350°F for 1–2 minutes if desired.
Notes
Do not pierce the casing before cooking — intact casings retain juices and produce the characteristic snap.
For a crispier exterior, score brats with 3–4 shallow diagonal cuts before cooking, but note this will reduce juiciness slightly.
A second batch cooks about 2 minutes faster in an already-hot basket.
Brats can also be cooked alongside sliced peppers and onions in the air fryer basket.
Air fryer brats are faster than grilling, easier than stovetop, and the results are genuinely impressive. Bratwurst — a German-style fresh pork sausage (from Brät, meaning finely chopped meat, and Wurst, meaning sausage) typically seasoned with nutmeg, ginger, caraway, and white pepper — browns exceptionally well in an air fryer, producing that satisfying snap when you bite through the skin while keeping the inside juicy and fully cooked. No grill required, no standing over a pot of simmering beer, no watching for flare-ups. The entire process takes about 15 minutes from fridge to plate.
- Air fryer brats are done in 12–15 minutes at 370°F — no pre-boiling or beer-simmering step required.
- Do not pierce the casing before cooking; intact casings retain juices and produce the characteristic snap.
- Fresh brats must reach 160°F internal temperature; use an instant-read thermometer, not cook time alone, to confirm doneness.
- Frozen brats cook from frozen at 350°F for 20–22 minutes — no thawing needed.
- Rest brats 3–5 minutes after cooking to allow juices to redistribute and internal temperature to stabilize.
This guide covers fresh bratwurst, pre-cooked brats, and frozen brats — each with specific temperatures and times so you get perfect results regardless of what you are starting with.
Why Is the Air Fryer Excellent for Bratwurst?
The air fryer is excellent for bratwurst because it solves the two core problems of every other cooking method: uneven browning and fat pooling. Bratwurst is a high-fat sausage — typically 30–35% fat by weight. That fat content is both what makes brats so flavorful and what makes cooking them tricky. On a grill, the rendered fat drips onto coals or burners and causes flare-ups that char the exterior unevenly. In a pan, the fat pools around the sausage and you end up essentially deep-frying them. In the air fryer, rendered fat drips through the basket grate and collects in the drip tray below, away from the sausage. The sausage browns in dry, circulating hot air rather than its own pooled fat.
The result is evenly browned, split-resistant brats with a snappy casing and a juicy interior. The air fryer handles the whole cooking process start to finish — no simmering in beer first, no two-step method needed. Fresh brats go straight in at 370°F and come out perfectly cooked in 12–15 minutes.

What You Need
- 4–6 bratwurst links — Fresh uncooked (Best for: maximum juiciness and customizable flavor), fully cooked/pre-cooked (Best for: speed and convenience on weeknights), or frozen (Best for: meal prep and last-minute meals). See timing chart below.
- Cooking spray or light oil (optional) — Brats have enough fat that they will not stick, but a light mist of cooking spray helps with cleanup.
- Brat buns — Hoagie rolls or traditional brat buns. Toast them in the air fryer for 1–2 minutes at 350°F after the brats are done.
- Toppings — Sauteed onions and peppers, mustard, sauerkraut, relish. Prepare toppings while the brats cook.
How to Cook Brats in the Air Fryer: Step by Step
Step 1: Prep the Air Fryer
Preheat the air fryer to 370°F (188°C) for 3 minutes. Preheating ensures the brats start browning immediately when they hit the basket. Lightly spray the basket with cooking spray if desired.
Do not pierce the brats before cooking. Piercing the casing releases the juices and fat that keep the interior moist throughout cooking. The whole point of the natural casing is to contain those juices. The air fryer temperature is gentle enough that brats will not burst or explode during cooking — that only happens at very high direct heat.
Step 2: Arrange Brats in the Basket
Place brats in a single layer in the basket. They can be close together but should not be stacked. In a standard 5–6 quart basket, 4–6 brat links fit comfortably side by side. For larger batches, cook in two rounds — the second batch cooks about 2 minutes faster in the already-hot basket.
Step 3: Cook According to Type
| Brat Type | Temperature | Total Time | Flip At | Target Internal Temp |
|---|---|---|---|---|
| Fresh/raw bratwurst | 370°F (188°C) | 12–15 min | 6–7 min | 160°F (71°C) |
| Pre-cooked/fully cooked brats | 370°F (188°C) | 8–10 min | 4–5 min | 165°F (74°C) |
| Frozen raw brats | 350°F (177°C) | 20–22 min | 10 min | 160°F (71°C) |
| Frozen pre-cooked brats | 370°F (188°C) | 12–14 min | 6 min | 165°F (74°C) |
Flip brats at the halfway point using tongs. Use an instant-read thermometer inserted into the center of the thickest brat to confirm doneness. According to the USDA Food Safety and Inspection Service (USDA FSIS, 2023), ground pork products — which includes sausages such as bratwurst — must reach a minimum internal temperature of 160°F to be considered safe to eat.
Step 4: Rest 3–5 Minutes
Remove brats from the air fryer and let them rest on a plate for 3–5 minutes before serving. The internal temperature continues to rise 3–5°F after removal, and resting allows the juices to redistribute within the casing. Cutting into a brat immediately after cooking causes the juice to run out onto the plate.
What Are the Best Tips for Perfect Air Fryer Brats?
The Scoring Technique (Optional)
Scoring brats before cooking — making 3–4 shallow diagonal cuts through the casing on each side — allows more of the casing surface to brown directly and creates appealing grill-mark-style lines. The trade-off is that scoring releases some juices during cooking, making the interior slightly less juicy compared to unscored brats. For maximum juiciness, skip scoring. For maximum browning and a crispier exterior, score at a 45-degree angle about a quarter inch deep.
Cooking Brats With Peppers and Onions
You can cook peppers and onions alongside the brats in the air fryer. Slice 1 bell pepper and half an onion into strips, toss with 1 teaspoon olive oil, salt, and pepper. Place the vegetable strips in the basket alongside the brats. Cook everything at 370°F for 12–15 minutes, shaking the vegetables at the halfway point when you flip the brats. The vegetables finish at the same time as the brats and are ready to pile directly onto the bun.
Beer Brat Flavor Without the Pot
If you want the flavor of beer-braised brats without the stovetop simmering step, marinate raw brats in lager or pilsner for 30–60 minutes before air frying. Pat the brats dry with paper towels before placing in the air fryer. The beer marinade seasons the casing and adds subtle flavor. Avoid hoppy IPAs — the bitterness can intensify unpleasantly when the moisture cooks off.
Serving Suggestions
While the brats rest, toast the buns in the air fryer at 350°F for 1–2 minutes. Classic brat toppings:
- Sauerkraut and spicy brown mustard: The traditional combination. The acidity of the sauerkraut cuts through the fat of the brat.
- Sauteed onions and stadium mustard: Simple, reliable, and classic.
- Bell peppers, onions, and ketchup: A heartier, slightly sweeter profile.
- Beer cheese sauce: Warm beer cheese or processed cheese sauce is a Wisconsin-style classic that works well with any brat flavor.
- Pickles and mustard: Quick pickle slices add crunch and acidity with zero extra prep time.
How Do You Store and Reheat Air Fryer Brats?
Cooked brats store in the refrigerator in an airtight container for up to 4 days. Reheat in the air fryer at 350°F for 4–5 minutes. The air fryer restores the casing snap that the refrigerator softens. Avoid reheating in the microwave — the casing becomes rubbery and the interior steams unevenly. Per the USDA FSIS (2023), cooked food should not sit at room temperature for more than 2 hours before refrigerating.
Frequently Asked Questions About Air Fryer Brats
Do you have to boil brats before air frying?
No — pre-boiling brats is unnecessary when using an air fryer. The pre-boiling or beer-simmering step is a technique used on the grill to ensure the interior is fully cooked before the exterior gets charred by high direct heat. The air fryer cooks more gently and evenly at 370°F — circulating air will fully cook the interior to 160°F before the exterior over-browns. That step is a workaround for grill cooking, and the air fryer simply does not have that problem.
How do I know when air fryer brats are done?
The most reliable method is an instant-read thermometer: fresh bratwurst should reach 160°F internal temperature, pre-cooked brats should reach 165°F (USDA FSIS, 2023). Visually, done brats are deep golden-brown to reddish-brown across the entire exterior, firm when pressed with tongs, and will produce a small amount of juice if you pierce the casing. Brats that are pale after the stated cook time likely need another 2–3 minutes — according to Consumer Reports (2025), air fryer output varies significantly by model, with some units registering up to 67°F below the set temperature.
Can I cook brats straight from frozen in the air fryer?
Yes — frozen brats cook directly in the air fryer with no thawing required. Cook frozen raw brats at 350°F for 20–22 minutes, flipping at the 10-minute mark. The lower temperature allows them to thaw evenly without burning the exterior. Always use a thermometer for frozen brats rather than relying on time alone — the internal temperature must reach 160°F throughout. Frozen pre-cooked brats are faster: 370°F for 12–14 minutes, flip at 6 minutes.
Why did my brats split open in the air fryer?
Splitting is almost always caused by cooking temperature that is too high or skipping the halfway flip. At temperatures above 400°F, the filling expands rapidly and creates enough pressure to burst the casing before it sets. Keep the temperature at 370°F or below for fresh brats, and flip at the halfway point. Avoid piercing brats before cooking — punctured casings are structurally weakened and far more likely to split under cooking pressure.
How many brats fit in an air fryer?
Most standard 5–6 quart basket-style air fryers hold 4–6 full-size bratwurst links in a single layer. Single-layer cooking is essential — stacked brats steam rather than brown where they contact each other. For larger batches, cook in two rounds; the second batch will finish about 2 minutes faster because the air fryer basket is already at temperature.
