Ingredients

• 2 cups broccoli florets, chopped
• 1 cup cauliflower florets, chopped
• 1 large zucchini, sliced into half-moons
• 1 red bell pepper, diced
• 1 yellow bell pepper, diced
• 1 cup mushrooms, sliced (button or cremini)
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 2 medium potatoes, peeled and cubed
• 1 cup shredded mozzarella cheese (or vegan cheese for dairy-free)
• 1/2 cup grated Parmesan cheese (optional)
• 1 cup heavy cream or coconut cream for vegan option
• 1/2 cup vegetable broth
• 2 tbsp olive oil
• 1 tsp dried thyme
• 1 tsp dried oregano
• Salt and pepper to taste
• 1/2 cup breadcrumbs for topping
• Fresh parsley for garnish

Equipment

• Large mixing bowl
• Sharp knife and cutting board
• Large skillet or sauté pan
• Oven-safe casserole dish (9×13 inches recommended)
• Measuring cups and spoons
• Wooden spoon or spatula
• Aluminum foil (optional)

Instructions

1. Preheat your oven to 375°F (190°C). Prepare your vegetables by washing and chopping them as described in the ingredients list.
2. Cook the potatoes. Boil the cubed potatoes in salted water for about 10 minutes or until just tender. Drain and set aside.
3. Sauté the aromatics and vegetables. Heat the olive oil in a large skillet over medium heat. Add the onions and garlic, cooking until translucent and fragrant, about 3-4 minutes.
4. Add the mushrooms, bell peppers, broccoli, cauliflower, and zucchini. Cook for about 7-8 minutes, stirring occasionally, until vegetables begin to soften. Season with dried thyme, oregano, salt, and pepper.
5. Combine cream and broth. In a separate bowl, whisk together the heavy cream and vegetable broth until smooth.
6. Mix all components. In a large mixing bowl, combine the sautéed vegetables, cooked potatoes, cream mixture, and half of the shredded mozzarella cheese. Stir gently to combine.
7. Transfer the mixture to your casserole dish. Spread it out evenly and top with the remaining mozzarella, Parmesan cheese, and breadcrumbs for a crunchy, cheesy crust.
8. Bake uncovered for 25-30 minutes. The casserole should be bubbly and the topping golden brown. If the topping browns too quickly, cover loosely with foil halfway through baking.
9. Remove from oven and let it cool slightly. Garnish with fresh parsley before serving.

Tips & Variations

Tip: To add extra flavor, sprinkle some crushed red pepper flakes or smoked paprika into the vegetable mixture before baking.

Variation: Replace the mozzarella with a plant-based cheese if you prefer a vegan casserole. You can also swap potatoes for sweet potatoes or add cooked quinoa for extra protein.

For a Mediterranean twist, add chopped olives, sun-dried tomatoes, and a sprinkle of feta cheese.
