Tuna Noodless Casserole

Brace yourselves. This is AMAZING. It truly tastes like tuna noodle casserole, and the textures all come together really well for this recipe! I don’t usually incorporate canned food into my recipes, but I made an exception here to capture the flavor of the casserole of my youth. The net carbs for each serving is 7g. This works well for my macros as a serving is quite large and is a complete meal.



  • 1 bag cauliflower rice (from Trader Joes) or one riced cauliflower.
  • 1 can cream of mushroom soup.
  • 2 14oz can mushrooms well drained (use only one can if you don’t really love mushrooms)
  • 1/2 cup heavy whipping cream or sour cream OR 2/3 cup sour cream
  • 2/3 cup frozen peas
  • 4 cans (5 oz each) tuna
  • 1 cup  and 1/2 cup finely shredded cheddar cheese
  • 1/4 tsp ground black pepper
  • 1/2 tsp sea salt

Preheat the oven to 400 degrees.

Microwave the riced cauliflower for seven minutes. Stir in remaining ingredients except for the 1/2 cup of cheddar cheese. Spread the mixture into a casserole dish. Sprinkle with remaining cheese. Bake for 20 minutes.

Makes 6 large servings.

  1. I didn’t know Teader Joe’s had cauliflower rice, so that was a great discovery.
    But what is the carb count? I can’t see where that’s posted.


    1. Nope! That’s the beauty of it. The key is to cook the cauliflower to death before adding in. It really just makes it more of a blank slate for flavor. I use cauliflower rice a lot in my recipes, and I don’t like the flavor of cauliflower normally. I always cook it enough that the flavor and smell are gone.


  2. Is the cauliflower rice frozen? or is it fresh? There are 2 different kinds. So sorry for all the questions! I really want to try it and not mess it up 🙂


  3. Made this for my son once a month ago and now it’s a weekly favorite super quick and so easy! Not an expensive meal either and will last a few days as an easy quick lunch or dinner perfect for our busy schedule! Thanks for the recipe!


  4. That was delicious! My husband loves the Keto recipes I make. He does not like mushrooms but he gobbled it up! I used 1 can of mushrooms, added a little parsley and used 1/2 the sour cream and 1/2 the heavy cream and cooked it for 30 minutes instead of 20
