Preheat the Oven:

Preheat your oven to 400°F (200°C).

Prepare Ingredients:

In a large mixing bowl, combine the sliced smoked sausages, cubed potatoes, diced bell pepper, and red onion.

Season the Mixture:

In a small bowl, mix the smoked paprika, red pepper flakes, salt, and pepper. Drizzle the olive oil over the sausage and vegetable mixture, sprinkle the seasoning blend, and toss everything to ensure even coating.

Transfer to Baking Sheet:

Line a large baking sheet with aluminum foil or parchment paper. Spread the sausage and vegetable mixture in an even layer on the prepared baking sheet.

First Bake:

Bake for 20 minutes in the preheated oven.

Add Garlic and Thyme:

Remove the baking sheet from the oven and stir in the minced garlic and dried thyme. Return the sheet to the oven and continue baking for another 15-20 minutes, or until the potatoes are golden and tender.

Add the Cheese:

Sprinkle the shredded white cheddar cheese evenly over the top of the roasted sausage and vegetables. Return to the oven for an additional 2-3 minutes, just until the cheese melts.

Garnish with fresh thyme or chopped parsley before serving. Enjoy warm.
