How to Make Crispy Air Fryer Brats with Sautéed Onions, Mustard, and Sauerkraut Recipe

Step 1: Prepare the Brats for Air Frying

Start by pricking each bratwurst a few times with a fork; this allows excess fat to escape as they cook, helping to achieve that coveted crispy exterior. Preheat your air fryer to 375°F (190°C) so it’s ready when the brats are. This quick prep sets the stage for brats that will be juicy inside but perfectly crisp on the outside.

Step 2: Air Fry the Bratwursts

Place the brats in a single layer in the air fryer basket, ensuring they have enough room to cook evenly. Air fry them for about 12-15 minutes, turning halfway through. The air fryer seals in the juices while caramelizing the surface, creating a satisfying snap at every bite that’s hard to beat.

Step 3: Sauté the Onions

While the brats are cooking, slice your onions thinly. Heat a skillet over medium heat with a small amount of butter or oil, then add the onions. Slowly sauté them, stirring often, until they turn golden and sweetly caramelized. The slow cooking process releases their natural sugars, making them a luscious topping that perfectly complements the savory sausage.

Step 4: Warm the Sauerkraut

Gently warm the sauerkraut in a small saucepan or microwave. Heating slightly mellows its acidity and blends beautifully with the other rich and tangy flavors of the dish. Warm sauerkraut is a comforting addition that brings a delightful zip to every bite.

Step 5: Assemble the Brats

If using buns, toast them lightly for extra texture. Place each brat inside a bun, if desired, then pile on the caramelized onions, a generous dollop or drizzle of mustard, and finish with sauerkraut. The layering of flavors and textures builds a mouthwatering masterpiece that’s both simple and spectacular.

How to Serve Crispy Air Fryer Brats with Sautéed Onions, Mustard, and Sauerkraut Recipe

Garnishes

Consider fresh herbs like chopped parsley or a sprinkle of paprika for a pop of color and a mild flavor boost. Adding extra mustard varieties on the side lets everyone customize their brat experience to suit their tastes perfectly.

Side Dishes

This dish pairs wonderfully with traditional sides like warm potato salad, crispy fries, or a light green salad. Each option adds balance—potato salad brings creaminess, fries offer crunch, and greens add freshness—rounding out an already robust meal.

Creative Ways to Present

For entertaining, serve these brats deconstructed on a platter with each component in bowls: crispy brats, sautéed onions, mustard varieties, and sauerkraut. Guests can build their ideal bites. Another fun idea is to slice the brats and serve them on pretzel rolls or as sliders for a festive touch.

Make Ahead and Storage

Storing Leftovers

Store any leftover cooked brats, sautéed onions, and sauerkraut in airtight containers in the refrigerator for up to 3 days. Keeping the components separate helps maintain their textures better than assembling beforehand.

Freezing

You can freeze cooked brats individually wrapped to prevent freezer burn, keeping them fresh for up to 2 months. Sauerkraut freezes well too, but sautéed onions are best prepared fresh for optimal flavor and texture.

Reheating

Reheat brats gently in an air fryer or a skillet to regain their crispiness. Warm the onions and sauerkraut on the stovetop or microwave until piping hot. Reheating components separately keeps this Crispy Air Fryer Brats with Sautéed Onions, Mustard, and Sauerkraut Recipe tasting fresh and vibrant.

FAQs

Can I use frozen bratwurst for this recipe?

Yes, you can use frozen brats, but be sure to increase the air frying time slightly and check for doneness to ensure they are cooked through without drying out.

What type of mustard works best?

Spicy brown mustard or Dijon mustard works beautifully because their tang and hint of heat complement the richness of the bratwurst and the sweetness of the onions.

Is it necessary to prick the brats before cooking?

Pricking helps release fat and prevents the brats from bursting, resulting in a better texture and less mess in the air fryer. However, if you prefer juicier sausages, you can skip this step.

Can I make this recipe gluten-free?

Absolutely. Just be sure to use gluten-free buns or skip the buns altogether, and verify that the sausages and mustard you choose do not contain gluten.

How long will leftovers keep in the fridge?

Stored properly in airtight containers, leftovers will stay good for up to 3 days. Always reheat thoroughly before eating.
