Ingredients

• 2 cups zucchini, diced
• 1 cup broccoli florets
• 1 cup carrot, shredded
• 1 medium onion, finely chopped
• 1.5 cups cheddar cheese, shredded
• 0.5 cup milk
• 2 tablespoons all-purpose flour
• 2 tablespoons butter, melted
• 1 teaspoon garlic powder
• 0.5 teaspoon dried thyme
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 0.5 cup breadcrumbs

Directions

Step 1

Prepare all vegetables: dice the zucchini, chop the broccoli into small florets, shred the carrot, and finely chop the onion.

Step 2

In a microwave-safe 2-quart casserole dish, combine the zucchini, broccoli, carrot, and onion. Toss them together evenly.

Step 3

In a small mixing bowl, whisk together the melted butter, milk, flour, garlic powder, thyme, salt, and pepper until smooth.

Step 4

Pour the milk mixture over the vegetables in the casserole dish and stir gently to coat all the vegetables with the sauce.

Step 5

Sprinkle 1 cup of shredded cheddar cheese over the vegetable mixture and lightly mix to distribute the cheese.

Step 6

Cover the dish loosely with microwave-safe plastic wrap or a microwave-safe lid, leaving a small vent for steam to escape.

Step 7

Microwave on high power for 10 minutes. Carefully stir the contents to ensure even cooking.

Step 8

Return the dish to the microwave and heat for another 10 minutes, or until the vegetables are tender and the mixture is bubbling.

Step 9

Remove the casserole from the microwave and evenly sprinkle the breadcrumbs and remaining 0.5 cup of shredded cheddar cheese on top.

Step 10

Microwave uncovered on high for 3–5 minutes, until the cheese is melted and the breadcrumbs are lightly toasted.

Step 11

Let the casserole stand for 5 minutes before serving. Serve warm as a side or standalone dish.
