Ingredients
  

Vegetables
  • 2 cups Broccoli cut into florets, about 2 inches long with 1.5-inch heads
  • 2 cups Cauliflower cut into 2-inch-long florets; ~1/2 head
  • 2 cups Zucchini sliced into thick circles, 3/8-inch thick; ~8 ounces
  • 2 cups Bell peppers cut into 1.5 inch pieces; ~1.5 large peppers
  • 2 cups Red onion cut into 1.5 inch pieces; ~1 medium onion
Seasoning
  • 1/3 cup Olive oil
  • 1/2 tbsp Garlic powder
  • 1/2 tbsp Italian seasoning
  • 1/2 tbsp Sea salt
  • 1/2 tsp Black pepper

Equipment

  • Oven
  • Extra-large baking sheet
  • Large bowl

Method
 

  1. Preheat the oven to 425 degrees F (218 degrees C). Line an extra-large baking sheet with foil or leave it bare. Spray with cooking spray.
  2. Combine all the vegetables in a large bowl. Drizzle with olive oil, and season with garlic powder, Italian seasoning, sea salt, and black pepper. Toss to coat.
  3. Arrange the vegetables in a single layer on the prepared baking sheet, making sure each piece touches the pan. Use multiple pans if needed to avoid crowding.
  4. Roast the vegetables in the oven for 15 minutes, on the rack one higher than the middle rack.
  5. Use tongs or a large turner to toss or flip the pieces. Roast for 8 to 15 more minutes, until the veggies are tender. If you want them browned, place them under the broiler for 2 to 3 minutes.

Notes

You can substitute vegetables based on availability. Cooking tips include using a single layer on the pan for best browning. Serving suggestions include pairing these roasted vegetables with grilled meat or fish for a simple meal.
