Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.

In a bowl, combine chopped asparagus, sliced carrots, and frozen peas.

In a saucepan over medium heat, mix heavy cream with garlic powder, salt, and pepper; stir until slightly thickened (about 5 minutes).

Pour the cream sauce over the vegetable mixture and stir until well coated.

Transfer the mixture into the greased baking dish; spread evenly.

Top with shredded cheddar cheese and sprinkle panko breadcrumbs.

Bake in the preheated oven for 30-35 minutes or until golden brown and bubbly.

Allow to cool slightly before serving.
