Ingredients You’ll Need

- 2 cups cauliflower florets (fresh or frozen)
- 1 cup carrots, sliced
- 2 cups shredded cheddar cheese, divided
- 1 can (10.5 oz) cream of mushroom soup

How to Make Cheesy Vegetable Casserole
1. Prepare the Vegetables
Wash and chop fresh broccoli and cauliflower into bite-sized florets. Slice the carrots thinly. If using frozen vegetables, no thawing is needed—just add them straight to the bowl.
2. Make the Cheese Mixture
In a large mixing bowl, combine the vegetables, cream of mushroom soup, 1½ cups shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Stir until everything is evenly coated in the creamy sauce.
3. Assemble the Casserole
Grease a 9×13-inch baking dish with olive oil or butter. Spread the vegetable mixture evenly in the dish to ensure even cooking.
4. Bake
Preheat oven to 350°F (175°C). Sprinkle the remaining ½ cup cheese and breadcrumbs evenly over the top. Bake uncovered for 25–30 minutes, or until the casserole is bubbly and the topping is golden brown. Let rest for a few minutes before serving.
