Slow Cooker Tuna Noodle Casserole

(Weight Watchers Friendly Crock Pot Cooking Day 129)

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.

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.

These are the rather tired looking leftovers, that still tasted yummy when I reheated them for a quick and easy lunch…

  2. Grease your slow cooker with nonstick cooking spray.
  3. Cook the noodles according to package instructions, until just a little underdone. Drain well and set aside.
  4. 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.
  5. Scrape the mixture evenly into your slow cooker.
  6. 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.

      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!
