Instructions

1. Step 1: Preheat your oven to 425°F and line a large sheet pan with parchment paper for easy cleanup.
2. Step 2: In a large bowl, toss 1 lb halved baby potatoes with 2 tbsp olive oil, 1 tsp dried oregano, 1 tsp dried basil, 1/2 tsp salt, and 1/4 tsp black pepper until evenly coated.
3. Step 3: Spread the potatoes on the sheet pan and roast for 15 minutes to start softening.
4. Step 4: Meanwhile, in the same bowl, combine 1 lb Italian sausage links, 1 large sliced red bell pepper, 1 large sliced yellow bell pepper, 1 medium cut red onion, 3 minced garlic cloves, 1 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper, tossing to coat.
5. Step 5: After the potatoes have roasted 15 minutes, add the sausage and vegetable mixture to the sheet pan, arranging sausages on top so they brown evenly.
6. Step 6: Roast everything together for an additional 20-25 minutes until the sausage is cooked through and vegetables are tender with slightly charred edges.
7. Step 7: Let rest for 5 minutes before serving to allow juices to redistribute.
