Follow this recipe and learn to make an easy and tasty vegetarian casserole.

Do you have to thaw frozen vegetables before cooking?

You don't need to thaw them as they will cook in the casserole. However, you should bear in mind that using frozen veggies means that your casserole texture might change. Frozen vegetables contain a lot of water, so your casserole might come out looking more like a vegetable stew. Unless you are aiming for a more watery consistency, we advise using thawed or fresh vegetables.

Vegetable Casserole


Makes 8 servings

  • 20 oz package of frozen mixed vegetables
  • 1 onion, chopped
  • 1-2 celery stalks, chopped
