What Is a Cheesy Vegetable Casserole?

A Cheesy Vegetable Casserole is a baked dish featuring a creamy, cheese-infused sauce mixed with vegetables — often potatoes, carrots, broccoli, peas, and cauliflower. It’s a beloved staple in vegetarian recipes for family dinners and is perfect for using up leftover vegetables.

Depending on the region, you might hear it called a vegetable cobbler, vegetable hot dish, or even a vegetable soup casserole, thanks to its creamy soup base. It’s designed to be flexible, budget-friendly, and incredibly satisfying.

This particular version includes a blend of frozen mixed veggies, shredded cheese, and a creamy base made with condensed soup. It bakes into a golden, bubbly dish that pairs perfectly with fresh bread or a light salad.

How to Make Cheesy Vegetable Casserole

Making this veggie casserole recipe couldn’t be easier — and it’s ready in under an hour!

1. Cook the Vegetables

If using frozen vegetables, cook according to package instructions until just tender. If using fresh, steam or boil for 5–7 minutes. Drain well to remove excess moisture — this helps prevent a watery casserole.

2. Prepare the Creamy Sauce

In a large mixing bowl, combine the condensed soup, sour cream, and seasonings. Stir until smooth. Add ¾ cup of shredded cheese and mix well.

3. Combine Everything Together

Add the cooked vegetables and cubed potatoes to the sauce. Stir gently to coat every piece evenly.

4. Transfer and Top

Spread the mixture into a greased 9×13-inch baking dish. In a small bowl, mix melted butter with crushed crackers or breadcrumbs, then sprinkle over the casserole. Top with the remaining cheese.

5. Bake Until Golden and Bubbly

Bake at 350°F (175°C) for 30–35 minutes, or until hot and bubbly with a golden crust. Let cool for 5 minutes before serving.

Tips for the Perfect Veggie Casserole

• Drain vegetables well: Extra water can make the casserole soggy.

• Add protein: Stir in cooked chicken, tofu, or beans for extra heartiness.

If you’re hosting a family dinner, this pairs perfectly with Garlic Herb Roasted Potatoes, Carrots, and Zucchini.
