Ingredients

  • 2 cups broccoli florets
  • 1 large sweet potato, peeled and diced
  • 1 red bell pepper, sliced
  • 1 zucchini, sliced into half-moons
  • 1 red onion, cut into wedges
  • 3 tablespoons olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • Salt and freshly ground black pepper to taste
  • Fresh parsley for garnish (optional)
  • Lemon wedges for serving (optional)

Equipment

  • Convection oven with adjustable temperature
  • Baking sheet or roasting pan
  • Mixing bowl
  • Measuring spoons
  • Knife and cutting board
  • Spatula or tongs for tossing

Instructions

  1. Preheat your convection oven to 400°F (200°C). This temperature is perfect for roasting vegetables to a crisp-tender finish.
  2. Prepare the vegetables: Wash and dry all your veggies. Peel and dice the sweet potato into 1-inch cubes, slice the zucchini into half-moons, cut the bell pepper into strips, and wedge the red onion.
  3. In a large mixing bowl, combine all the vegetables. Drizzle with olive oil and sprinkle with garlic powder, smoked paprika, salt, and pepper.
  4. Toss everything together until the vegetables are evenly coated with oil and spices.
  5. Spread the vegetables in a single layer on your baking sheet. Avoid overcrowding to ensure even roasting and crispiness.
  6. Place the baking sheet in the convection oven and roast for 20-25 minutes. Toss or flip the vegetables halfway through the cooking time for even browning.
  7. Check for doneness: The vegetables should be tender inside with a slight char on the edges.
  8. Remove from oven and transfer to a serving platter. Garnish with fresh parsley and serve with lemon wedges for an added zing.

Tips & Variations

“For perfectly roasted vegetables every time, make sure to cut your veggies into similar sizes. This ensures even cooking and prevents some pieces from burning while others remain undercooked.”

  • Mix and match veggies: Try adding carrots, Brussels sprouts, or cauliflower to the mix for different textures and flavors.
  • Add herbs: Sprinkle fresh or dried thyme, rosemary, or oregano on veggies before roasting for an aromatic twist.
  • Spice it up: Incorporate a pinch of cayenne pepper or check out our Chilli Powder Recipe Vegan: Easy Homemade Spice Blend to add smoky heat.
  • Make it a meal: Toss roasted veggies with cooked quinoa or lentils for a hearty vegetarian bowl inspired by our Ancient Grains Vegetarian Recipes for Healthy Delicious Meals.
  • Use parchment paper: Line your baking sheet with parchment paper to prevent sticking and make cleanup easier.
