Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 2 peeled and chunked carrots, 2 chopped zucchinis, 1 chopped red bell pepper, and 1 wedged 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: Spread the vegetables in a single layer on a large baking sheet and roast for 25-30 minutes, tossing halfway through, until vegetables are tender and edges are caramelized.
  3. Step 3: Meanwhile, combine 1/3 cup balsamic vinegar and 1 tbsp honey in a small saucepan over medium heat. Bring to a simmer and cook for 5-7 minutes until the mixture thickens into a syrupy glaze.
  4. Step 4: Drizzle the balsamic reduction over the roasted vegetables and gently toss to combine before serving warm.
