Instructions

1. Step 1: Preheat oven to 400°F. On a large rimmed baking sheet, toss 2 sliced fennel bulbs and 1 cut red onion with 3 tbsp olive oil, 1 tbsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper until evenly coated.
2. Step 2: Nestle 4 Italian sausage links among the vegetables on the sheet pan. Roast in the oven for 30-35 minutes, turning the sausage halfway, until the sausage is browned and cooked through and fennel edges are caramelized.
3. Step 3: Remove from oven and squeeze juice of 1 lemon over the sausage and vegetables for a bright finish. Let rest for 5 minutes before serving.
