Air-Fryer Bratwurst with Onions & Peppers

Juicy pork bratwursts star in these healthy sandwiches. Topping them with onions, peppers and a spicy mustard sauce takes them over the top. Be sure to seek out prepared horseradish from the refrigerated section at the supermarket—not the creamy horseradish sauce shelved near the ketchup and mustard.

Nutrition Profile:


  • 2 medium red bell peppers, sliced

  • 1 medium yellow onion, sliced

  • 1 jalapeño pepper, halved lengthwise, seeded and sliced

  • 1 tablespoon extra-virgin olive oil

  • ½ teaspoon garlic powder

  • ¼ teaspoon ground pepper, plus more to taste

  • 5 smoked pork bratwurst

  • Cooking spray

  • ¼ cup olive oil mayonnaise

  • 1 tablespoon prepared horseradish

  • 2 teaspoons whole-grain mustard

  • ½ teaspoon hot sauce

  • 5 whole-wheat hot dog buns, split and toasted


  1. Preheat air fryer to 375℉ for 5 minutes.

  2. Combine bell peppers, onion, jalapeño, oil, garlic powder and pepper in a large bowl.

  3. Working in batches as necessary, arrange the peppers and onions in an even layer in the basket of an air fryer. Nestle brats in the vegetables, making sure the brats touch the basket; coat the tops of the brats with cooking spray.

  4. Cook, tossing the vegetables and flipping the brats once, until an instant-read thermometer inserted in the centers of the brats registers 160℉, 15 to 17 minutes.

  5. Meanwhile, combine mayonnaise, horseradish, mustard and hot sauce in a small bowl; season with pepper to taste.

  6. Spread about 1 tablespoon of the mayonnaise mixture onto each bun; top with the vegetables and brats.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
