Ingredients

  • 2 tbsp olive oil
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 1 zucchini, sliced
  • 2 carrots, thinly sliced
  • 1 cup broccoli florets
  • 1 cup cauliflower florets
  • 1 bell pepper, chopped
  • 2 potatoes, thinly sliced
  • 1 cup cream or milk
  • 1 ½ cups shredded cheddar cheese, divided
  • ¼ cup grated parmesan cheese
  • 1 tsp dried herbs (thyme, oregano, or Italian seasoning)
  • Salt and pepper to taste
  • ½ cup breadcrumbs (optional topping)

Instructions

  1. Preheat oven to 375°F (190°C).

  2. Heat olive oil in a skillet over medium heat. Sauté onion and garlic until soft and fragrant.

  3. Add potatoes, carrots, and cauliflower. Cook for 5 minutes to soften slightly.

  4. Stir in zucchini, bell pepper, and broccoli. Season with salt, pepper, and dried herbs.

  5. In a bowl, whisk cream or milk with half of the shredded cheddar cheese.

  6. Transfer cooked vegetables to a greased baking dish. Pour the cheese-cream mixture evenly over the top.

  7. Sprinkle remaining cheddar cheese, parmesan, and breadcrumbs (if using) over the top.

  8. Bake uncovered for 35–40 minutes, until veggies are tender and top is golden brown.

  9. Let casserole rest 5–10 minutes before serving.


Notes

  • Add cooked quinoa or rice to the veggie mix for a more filling casserole.

  • To make it vegan, use plant-based milk and cheese alternatives.

  • Top with fresh tomato slices for brightness, or chili flakes for a spicy kick.

  • Use thawed, well-drained frozen vegetables to save time.

  • Pre-sautéing veggies helps prevent excess moisture in the final bake.
