Brats in the air fryer are one of those easy dinners that feel almost too simple to work, but they really do. You get juicy sausage on the inside, a nicely browned outside, and barely any cleanup. I love this method on busy nights because it gives you that classic brat flavor without standing over the stove.
Why I Love This Recipe
What I love most is how easy it is to get great results. You do not need a grill, you do not need fancy prep, and you do not need to babysit the pan. Just pop them in, flip once, and they come out looking like you worked a lot harder than you did.

Brats in the Air Fryer Recipe
Step 1: Preheat the air fryer
Preheat your air fryer to 360°F for 3 to 5 minutes. Starting with a hot air fryer helps the brats cook more evenly and brown better on the outside.
Step 2: Add the brats
Place uncooked bratwursts in the air fryer basket in a single layer. Leave a little space between each brat so the hot air can move around them. Do not stack them.
Step 3: Air fry the brats
Cook the 5 bratwursts at 360°F for 5 to 6 minutes. Open the basket and flip each brat with tongs. Cook for another 5 to 6 minutes, until the outsides are browned and the centers reach 160°F. The exact time can vary a little depending on the thickness of the brats and your air fryer model.
Step 4: Toast the buns
If you want toasted buns, brush the insides of 5 hot dog buns with 1 tablespoon olive oil. Place them in the air fryer for 1 to 2 minutes at 360°F, just until lightly golden around the edges. Watch them closely because buns toast fast.
Step 5: Serve
Place 1 cooked brat in each bun. Top with thinly sliced onion, mustard, and sauerkraut if using. Serve right away while the brats are hot and juicy.
Pro Tips
- Do not overcrowd the basket. Space between the brats helps them brown better.
- Flip them halfway through cooking so both sides color evenly.
- Use a meat thermometer if you want the most reliable results. Brats should reach 160°F in the center.
- Toast the buns at the end, not the beginning, so they stay warm and do not dry out.
- Let the cooked brats rest for 2 minutes before serving if you want them extra juicy.
Why This Recipe Works (Quick Science)
Air fryers cook with fast-moving hot air. That moving air helps the outside of the brats brown while the inside heats through. The brat casing tightens as it cooks, which helps hold in juices. Flipping halfway through gives both sides direct exposure to the hot air, so the sausages brown more evenly instead of getting too dark on just one side.
Substitutions and Variations
- Use beer brats, cheddar brats, or spicy brats instead of plain bratwursts
- Swap hot dog buns for hoagie rolls or sturdy sandwich rolls
- Use red onion instead of onion for a sharper bite
- Add grilled peppers for more flavor
- Top with barbecue sauce instead of mustard for a sweeter twist
- Skip the bun and serve the brats sliced over mashed potatoes or roasted vegetables
Make Ahead Tips
You can slice the onion and get your toppings ready up to 1 day ahead. You can also cook the brats ahead of time, cool them, and store them in the fridge. Reheat them in the air fryer at 350°F for 3 to 4 minutes before serving.
What to Serve With
Brats are great with simple sides that do not need much work.
- Potato salad
- French fries or air fryer fries
- Baked beans
- Coleslaw
- Macaroni salad
- Roasted peppers and onions
- Pickles or cucumber salad
Common Mistakes
- Packing too many brats into the basket. That makes them steam instead of brown.
- Cooking at too high a temperature. The outside can get too dark before the middle is done.
- Skipping the flip. One side may brown much more than the other.
- Not checking doneness. Thicker brats sometimes need an extra minute or two.
- Toasting the buns too long. They can go from golden to too dark very fast.
Leftovers and Storage
Store leftover cooked brats in an airtight container in the fridge for up to 4 days. Reheat in the air fryer at 350°F for 3 to 4 minutes, or until heated through. You can also freeze cooked brats for up to 2 months. Thaw in the fridge before reheating for the best texture.

FAQ
Can I cook frozen brats in the air fryer?
Yes. Add a few extra minutes to the cook time. Start with 7 minutes, flip, then cook 6 to 8 minutes more, checking that the center reaches 160°F.
Do I need to poke holes in brats before cooking?
No. Leave them whole. Poking holes can let the juices run out, and that can make them less juicy.
Can I put buns in the air fryer?
Yes. Toast them for 1 to 2 minutes at 360°F and keep a close eye on them.
How do I know when brats are done?
The safest way is to use a meat thermometer. The center should reach 160°F.
Can I add peppers and onions to the air fryer too?
Yes, but cook them separately or give them enough room. If the basket gets too crowded, the brats will not brown as well.
Final Thoughts
Brats in the air fryer are easy, fast, and seriously satisfying. This is the kind of meal that saves dinner when you want something hot and hearty without making a mess.
