  • 1 medium zucchini, cut into ½-inch pieces
  • 1 medium yellow squash, cut into ½-inch pieces
  • 1 small red onion, cut into 1-inch long thin strips
  • 1 red bell pepper, cut into 2-inch long thin strips
  • 1 green bell pepper, cut into 2-inch long thin strips
  • 1 cup mushrooms, coarsely chopped

Seasonings & Oil

  • 3 tablespoons olive oil
  • ¾ teaspoon salt (or to taste)
  • ¼ teaspoon black pepper
  • 1 ½ teaspoons Italian seasoning
  • Fresh parsley (optional, for garnish)

Instructions

  1. Preheat the oven: Set your oven to 425°F (220°C) to ensure it’s hot and ready for roasting the vegetables evenly.
  2. Prepare the vegetables: Chop the zucchini, yellow squash, red onion, red and green bell peppers, and mushrooms as directed. Place them all in a large mixing bowl.
  3. Season the vegetables: Drizzle the olive oil over the vegetables. Sprinkle salt, black pepper, and Italian seasoning on top. Toss everything thoroughly to coat the veggies evenly with oil and seasonings.
  4. Arrange on baking sheet: Line a large baking sheet with parchment paper. Spread out the seasoned vegetables on the sheet in a single layer to promote even roasting.
  5. Roast the vegetables: Place the baking sheet in the preheated oven. Roast for 25-30 minutes, stirring and tossing the vegetables halfway through cooking to ensure uniform browning and tenderness.
  6. Serve: Once the vegetables are tender and slightly caramelized, transfer to a serving dish. Garnish with fresh parsley if desired and enjoy this delicious, healthy side dish!

Notes

  • For extra flavor, add minced garlic or a splash of balsamic vinegar before roasting.
  • Make sure the vegetables are cut into similar sizes to ensure even cooking.
  • You can substitute vegetables with others like eggplant, carrots, or cherry tomatoes as preferred.
  • Leftovers store well in an airtight container in the refrigerator for up to 3 days.
  • Use parchment paper to prevent sticking and for easy cleanup.
