I made this easy Lightened-Up Slow Cooker Tater Casserole this week. I will be making this instead of my favorite comfort food Tater Tot Casserole when I am trying to eat healthier. My husband and I really enjoyed the meal! I used refrigerated style shredded hash browns in place of the tater tots.

Replacing the tater tots with the hash browns cut the majority of the calories in the dish. Other changes I made was I used low-fat meat, healthy request cream of mushroom soup, and used weight watchers cheese.

    Hi- I’m making this tonight. Do you have the nutrition information? I’m on weight watchers so I need to calculate the points. I’m going to substitute the beef with ground turkey. Thanks!

    1. Sarah Olson says:

      Sorry I am just getting back to you. I had figured out the nutrition and lost it. But I just got the nutritional information for you from My Recipe Magic. If you click on the Magic button that is under the recipe box, (then click on nutrition), you will find the info! I hope this helps.
