Prep the potatoes. If using fresh potatoes, peel (optional) and shred.
Rinse the shreds in cold water until it runs clear, then squeeze out as much water as possible using a clean towel. This step is key for crispiness.
Season the hash browns. In a bowl, toss the shredded potatoes (or thawed frozen shreds) with 1 tablespoon oil, 1 teaspoon salt, 1/2 teaspoon pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon paprika. Add chopped onion and bell pepper if you like.
Preheat the air fryer. Set it to 380°F (193°C) for 3–5 minutes.
A hot basket helps hash browns crisp.
Start the sausages. Lightly oil the air fryer basket. Add the sausages in a single layer. Cook at 380°F (193°C) for 6 minutes.
Add the hash browns. Push the sausages to one side (or remove temporarily if space is tight).
Spread the seasoned potatoes in a thin, even layer. Avoid piling them up; thin layers = more crunch.
Air fry together. Cook at 380°F (193°C) for 10–12 minutes, shaking or flipping halfway through. If using patties, flip them once.
Check that sausages reach 160°F (71°C) for pork or 165°F (74°C) for poultry.
Finish for extra crisp. If the potatoes need more color, remove sausages and cook the hash browns another 3–5 minutes at 400°F (204°C). Watch closely to prevent burning.
Garnish and serve. Sprinkle with chopped herbs. Plate with eggs or your favorite sauce.
Serve hot while the edges are crispy.
