Cheesy vegetable casserole is my go-to side dish for family events and holidays. It’s loaded with vegetables, cheese and topped off with crumbly, buttery crackers. This is a great way to get the kiddos to eat their veggies.

Ingredients needed

  • Frozen vegetables – Use your favorite mix of frozen vegetables for this dish.
  • Cream of mushroom soup – Gives the mixture a creamy texture.
  • Sour cream – Adds a little tang and more creaminess.
  • Onion – Diced onion is used.
  • Cheese – Shredded cheddar cheese takes this casserole to the next level.
  • Butter – Melted butter helps to make the cracker topping.
  • Crackers – I like using Ritz crackers but you can use your favorite buttery cracker.

How to make frozen vegetable casserole

  • Filling – Stir together frozen vegetables, sour cream, cheese, onions, and cream of mushroom soup. Spread in a casserole dish sprayed with non-stick cooking spray.
  • Crust – Mix crushed crackers with melted butter. Spread the mixture over the filling. Bake in the oven until the crackers turn golden brown.

  1. I made this for a funeral dinner a while back and it was a huge hit. Then I lost the recipe I printed out. There are many ‘similar’ recipes like this-but this one is the winner. I’ve spent most of the morning searching, and finally found. Thank goodness. I’ve now saved it in 3 of my boards, haha. Thanks for such a tasty side.
