Ingredients

  • 2 cups chopped zucchini
  • 2 cups chopped bell peppers (red, yellow, or orange)
  • 1 cup cherry tomatoes
  • 1 cup sliced mushrooms
  • 1 medium red onion, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and pepper to taste
  • 1 cup cooked quinoa (optional for added protein)
  • 1/2 cup crumbled feta cheese or vegan cheese alternative (optional)
  • Fresh parsley for garnish

Equipment

  • Large mixing bowl
  • Baking sheet or oven-safe casserole dish
  • Sharp knife and cutting board
  • Measuring spoons
  • Oven mitts
  • Spatula or tongs

Instructions

  1. Preheat the oven to 400°F (200°C). Prepare your baking sheet or casserole dish by lightly greasing it with a bit of olive oil to prevent sticking.
  2. In a large mixing bowl, combine the chopped zucchini, bell peppers, cherry tomatoes, sliced mushrooms, and red onion.
  3. Add the minced garlic, olive oil, dried oregano, dried basil, salt, and pepper. Toss everything together until the vegetables are evenly coated with the oil and seasoning.
  4. Spread the vegetable mixture evenly on the prepared baking sheet or casserole dish. Make sure the veggies are in a single layer to ensure even roasting.
  5. Bake in the preheated oven for about 25-30 minutes, stirring halfway through the cooking time. The vegetables should be tender and slightly caramelized around the edges.
  6. If using, stir in the cooked quinoa and sprinkle the crumbled feta or vegan cheese over the top. Return to the oven for an additional 5 minutes to warm through and melt the cheese slightly.
  7. Remove from the oven and garnish with fresh parsley. Serve warm and enjoy your nutritious oven-baked vegetarian meal!

Tips & Variations

For an extra burst of flavor, add a splash of balsamic vinegar or a sprinkle of chili flakes before baking.

You can easily customize this recipe by swapping out vegetables based on what’s in season or what you have on hand. Try adding eggplant, sweet potatoes, or broccoli for different textures and flavors.

For a heartier meal, mix in cooked lentils or chickpeas before baking. If you prefer a vegan version without cheese, a sprinkle of nutritional yeast can add a cheesy flavor without dairy.

To make this dish gluten-free and protein-packed, quinoa is a perfect addition. For an effortless weeknight dinner, prepare the veggies ahead of time and store them in the fridge, then simply bake when you’re ready to eat.
