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.
Ingredients:
- 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.

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.

For the entire recipe, or for the cauliflower rice itself?

Can you taste the cauliflower in this?
LikeLike
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.

Can I use cream cheese instead of the heavy cream?

It is certainly worth a shot! Did you give it a try, and how did it turn out?

is it really 2, 14 oz cans of mushrooms? I can only seem to find 4 oz or 8 oz cans

Yes, I use that much for the mushrooms though I really love them. You can always make it with less to experiment and adjust afterward.

Do you drain the tuna? (i would assume so, but I just want to make sure that the liquid isn’t needed for the dish)
LikeLike
Yes, definitely drain the tuna.

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 🙂

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
