I was craving comfort food yesterday, so made this Slow Cooker Tuna Noodle Casserole for supper. Both Rod and I are big fans of creamy casseroles, so this was a winner with us.

I adapted the original recipe, making it a little more WW friendly.

Recipe Notes

I used the classic tuna noodle casserole recipe from my childhood, made a few substitutions to lighten it and adapted it for the slow cooker.

You could bulk this up with the addition of a wide variety of vegetables—sliced mushrooms, corn, mixed vegetables, chopped broccoli, spinach, etc.

Served with a simple green salad, to which I added a chopped ripe pear, the combination of flavors and textures made for a satisfying meal. I will definitely make this tuna casserole again the next time a comfort food craving strikes.

Optional Additions and Variations

  • 1/4 cup chopped roasted red bell pepper

Ingredients 

  • 2 cups no-yolk egg noodles
  • 1 can (10.75 ounces) fat free cream of mushroom soup (I used Campbell's Healthy Request)
  • 1/2 cup evaporated skim milk
  • 2 cans (5 ounces each) tuna in water, drained well
  • 1/2 cup shredded reduced fat cheddar cheese
  • 1 tablespoon parsley
  • Salt and pepper to taste
  • 1 cup frozen peas
  • Paprika for garnish if desired

Instructions 

  • Ideal Slow Cooker Size: 4-Quart.
  • Grease your slow cooker with nonstick cooking spray.
  • Cook the noodles according to package instructions, until just a little underdone. Drain well and set aside.
  • In a large bowl, mix the soup and milk until well blended and creamy. Stir in the well drained tuna, cheese, parsley and salt and pepper until well combined. Add the noodles and toss gently to combine.
  • Scrape the mixture evenly into your slow cooker.
  • Cover and cook on LOW for 3 to 4 hours or on HIGH for 1-1/2 to 2 hours or until heated through, stirring occasionally if possible.
  • Twenty minutes before the end of cooking time, stir in the peas and reduce heat to LOW.
  • Sprinkle with a little paprika, if desired, before serving.

    1. Hi Kelly,

      I think it would be fine to double the recipe. My 4-Quart oval slow cooker was less than half full so there should be plenty of room. I think cooking time will depend a lot on your specific slow cooker. My casserole was very warm after 3 hours on LOW, so I think a double recipe in my cooker would be plenty warm within 4 hours. But every cooker is different. You are really just warming it, because all the ingredients are already cooked!
