Swiss Vegetable Casserole is a dump-and-bake dish that transforms raw veggies (or thawed frozen!) into a creamy, cheesy casserole topped with crunchy fried onions.  What's great about this dish is that you can use whatever vegetables you have on-hand- you just need 5 1/2 cups!  You can use all broccoli or a mixture of broccoli and cauliflower.  And any condensed cream soup will work, too, melting into a creamy sauce that bakes with sour cream and Swiss cheese, turning your veggies into pure comfort food!


cost per recipe: $6.75

  • 1 can (10 1/2 ounces) Campbell’s® Condensed Cream of Mushroom Soup or 98% Fat Free Cream of Mushroom Soup
  • 1/3 cup sour cream
  • 1 container (2.8 ounces) French's® French Fried Onions (about 1 1/3 cups) (amount divided in recipe steps below)
  • 1/2 cup  shredded Swiss cheese (amount divided in recipe steps below)
  • 3 cups small fresh broccoli florets (about 6 ounces)
  • 1 1/4 cups small fresh cauliflower florets (about 4 ounces)
  • 1 1/4 cups baby-cut carrots (about 4 ounces)


  • Tips

    • Feel free to change up the cheese!  You can use shredded cheddar, or Monterey Jack or a shredded cheese blend instead of the Swiss, they will all work!
    • More veggie options!  You can use fresh or thawed frozen broccoli, cauliflower and carrots in this recipe.
  • Step 1

    Heat the oven to 400°F.  While the oven is heating, stir the soup, sour cream, 2/3 cup onions and 1/4 cup cheese in a 2-quart casserole. Season with salt and pepper.  Add the vegetables and stir to coat.  Cover the casserole.

  • Step 2

    Bake for 40 minutes or until the vegetables are tender.  Stir the vegetable mixture.  Top with the remaining onions and cheese.

  • Step 3

    Bake for 5 minutes or until the cheese is melted.

    I love this casserole recipe. I've been making it for years and it has become a holiday staple in my family. I do change it up periodically, though, by using cream of broccoli soup instead of mushroom. I always use a combo of swiss/mozzarella cheese-and more than the recipe calls for. Extra onions are added too, mainly on top for the crunch factor.

    I use all broccoli instead of mixed veggies and it is wonderful.
