Equipment

  • 9×13-inch baking dish
  • saucepan
  • Whisk
  • steamer or pot
  • mixing spoon

Ingredients
  

  • 2 cups broccoli florets
  • 2 cups cauliflower florets
  • 1 cup sliced carrots
  • 1 cup chopped zucchini (optional)
  • 1 cup chopped bell peppers (optional)
  • 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 2 cups milk
  • 2 cups shredded sharp cheddar cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 1/2 tsp garlic powder
  • 1/4 tsp ground nutmeg
  • salt and pepper, to taste
  • 1/2 cup breadcrumbs
  • 2 tbsp melted butter (for topping)

Instructions
 

  • Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  • Blanch or steam the broccoli, cauliflower, and carrots until just tender. Pat dry if using frozen vegetables.
  • In a saucepan, melt the butter over medium heat and whisk in the flour to form a smooth roux.
  • Gradually whisk in the milk and cook until the sauce thickens.
  • Remove from heat and stir in cheddar, mozzarella, garlic powder, nutmeg, salt, and pepper until smooth.
  • Spread the vegetables evenly in the prepared baking dish and pour the cheese sauce over them.
  • Mix breadcrumbs with melted butter and sprinkle over the casserole. Top with Parmesan cheese.
  • Bake uncovered for 25–30 minutes, until bubbly and golden brown.
  • Let the casserole rest for 10 minutes before serving.

Notes

Pre-cook watery vegetables like zucchini to avoid excess moisture. Always shred cheese from the block for smoother melting. Let the casserole rest before serving for cleaner slices.
