Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Peel and dice carrots into 1/2-inch cubes, cut broccoli into small florets, and slice bell pepper into thin strips.
  2. Step 2: Toss carrots, broccoli, and bell pepper with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread on a parchment-lined baking sheet and roast for 20 minutes until edges are crispy and vegetables are tender.
  3. Step 3: Cook pasta in a large pot of salted water for 8 minutes until al dente. Drain and return to pot.

  5. Step 5: Add roasted vegetables to the pot with pasta, then pour in herb butter. Toss gently until evenly coated. Stir in 1/4 cup parmesan, then serve immediately with remaining parmesan and parsley.
