Ingredients
6 bratwursts
2 large onions, thinly sliced
2 cloves garlic, minced
1 tablespoon olive oil
2 tablespoons butter
1 (12-ounce) bottle of beer (pilsner or lager works best)
1 cup beef broth
1 tablespoon Dijon mustard
Salt and pepper, to taste
Fresh parsley, for garnish (optional)
Step-by-Step Air Fryer Instructions
Step 1: Prepare the Onions
In a large skillet on the stovetop, heat the olive oil and butter over medium heat.
Add the thinly sliced onions and cook for 10–12 minutes, stirring occasionally, until they begin to caramelize.
Stir in the minced garlic and cook for 1 more minute.
(Note: Air fryers can’t caramelize onions properly on their own, so starting them on the stovetop ensures deep flavor.)
Step 2: Deglaze with Beer & Broth
Pour the beer, beef broth, and Dijon mustard into the skillet.
Stir to dissolve the mustard.
Season with salt and pepper to taste.
Simmer for 3–4 minutes to blend the flavors.
Step 3: Preheat the Air Fryer
Preheat the air fryer to 370°F (188°C) for best browning.
Step 4: Air Fry the Brats
Place the bratwursts in a single layer in the air fryer basket.
Air fry for 12–15 minutes, turning halfway through, until golden brown and cooked to an internal temperature of 160°F (71°C).
Step 5: Combine Brats with Sweet Onions
Once the brats are cooked, add them into the skillet with the onion-beer mixture.
Simmer for 5 minutes to allow the brats to soak up all the rustic flavor.
Step 6: Serve Warm
Serve the bratwursts smothered in the sweet, buttery onions.
Garnish with fresh parsley if desired.
Perfect with:
Crusty bread
Mashed potatoes
Air fryer potatoes
Sauerkraut
Grainy mustard
Tips & Variations
Variations
No Beer? Substitute with apple cider or additional beef broth.
Add Veggies: Bell peppers or mushrooms make great additions.
Spicy Twist: Add red pepper flakes or spicy mustard to the broth mix.
German-Style: Serve with sauerkraut and stone-ground mustard.
Tips
Don’t pierce the brats, or they may dry out.
Preheating the air fryer helps them brown evenly.
You can air fry the onions in foil packets, but stovetop caramelization gives far better flavor.
To thicken the sauce, simmer longer or mix in a teaspoon of cornstarch slurry.
