Ingredients
  

Russet potatoes
  • 2 lb russet potatoes
Smoked sausage and aromatics
  • 14 oz smoked sausage
  • 1 tbsp olive oil
  • 1 tbsp cajun seasoning
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp paprika
  • 0.5 tsp black pepper
Cheese and toppings
  • 2 shredded cheddar cheese
  • 4 slice bacon cooked and crumbled
  • 3 green onions sliced
  • 0.25 cup sour cream optional for serving

Equipment

  • 1 sheet pan

Method
 

Prep the oven and pan
  1. Preheat the oven to 425°F (220°C) so it’s hot when the potatoes go in.
  2. Line a large sheet pan with parchment paper for easy release and cleanup.
Season and bake the potatoes
  1. Toss diced russet potatoes with olive oil, Cajun seasoning, garlic powder, onion powder, paprika, and black pepper until evenly coated.
  2. Spread the potatoes in an even layer on the sheet pan so they crisp instead of steam.
  3. Bake for 25 minutes, watching for edges to start drying and browning.
Add sausage and finish crisping
  1. Stir in the sliced smoked sausage so it heats through and mingles with the potato juices.
  2. Continue baking for 15–20 minutes until the potatoes are golden and crispy.
Melt and top
  1. Transfer the potato mixture to a serving dish.
  2. Sprinkle the shredded cheddar cheese over the hot potatoes so it begins melting right away.
  3. Wait 2–3 minutes for the cheese to melt visibly and cling to the crispy edges.
  4. Top with crumbled bacon and sliced green onions for a fresh, smoky finish.
  5. Serve with sour cream if desired.

Notes

For extra crisp edges, spread the potatoes in a single layer with space between pieces and avoid crowding the pan. Store leftovers in the refrigerator up to 3 days. Reheat in a hot oven (or air-fryer) to bring back crispness; freezing is not recommended because the potatoes and cheese can soften and separate. If you want a lighter option, use turkey sausage and reduced-fat cheddar to cut calories while keeping the Cajun flavor.
