Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Toss zucchini, yellow squash, bell pepper, and red onion on a large baking sheet with 2 tbsp olive oil, minced garlic, 1/2 tsp salt, and 1/4 tsp black pepper. Arrange in a single layer to ensure even roasting.
  2. Step 2: Roast in the preheated oven for 15 minutes until vegetables begin to soften and develop light golden edges.
  3. Step 3: Remove from oven and sprinkle with chopped rosemary, lemon zest, and remaining 1 tbsp olive oil. Toss gently to coat all vegetables evenly.
  4. Step 4: Return to oven and roast for an additional 10-12 minutes until vegetables are tender-crisp with deeply caramelized edges and fragrant aromatics.
  5. Step 5: Check for doneness by piercing a pepper piece with a fork — it should yield easily but still hold its shape. The dish is ready when vegetables are evenly browned and fragrant from the rosemary and garlic.
