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 Toppings
Sprinkle on top, just before serving, if desired: Crushed potato chips, cornflake crumbs or cracker crumbs.
Optional Additions and Variations
- Use short curly fusilli pasta instead of noodles
- Cream of celery soup in place of cream of mushroom
- 6 ounces sliced and drained canned mushrooms or cooked mushrooms
- 1/4 cup chopped roasted red bell pepper
- 1 cup chopped cooked broccoli

Slow Cooker Tuna Noodle Casserole
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.

I would like to try this. How many Smart Points would this be per serving
Is the 2 cups of noodles dry or cooked?
Hi Shawna, uncooked. – Martha
Just wondering if you could double the recipe and how it would change the cooking time?
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!
Can’t wait to try this one. It brings back good childhood memories.
For me to Theresa! I think it’s hard to beat the yummy flavors of childhood ๐
