Classic Tuna Noodle Casserole [Low Carb & Keto]

This classic tuna casserole recipe uses Great Low Carb Bread Co. rotini noodles, so the carb count is only 6g per serving.  This Keto version is even better than the original.

If you are looking for some pure retro comfort food, then you’ve come to the right place.

In fact, we’ve been waiting all day for you to come home from work. And we’ve prepared your favorite dish, tuna noodle casserole. So tuck a napkin into your collar and dig right in!

Just kidding, you are going to have to make this tuna noodle casserole all by yourself.

But the good news is that this casserole is low carb and Keto compliant. That’s because this recipe uses a rotini noodle that is made by the Great Low Carb Bread Co. It’s a low carb noodle that actually has a relatively high amount of carbs, but it also has a very high amount of fiber. So the total net carbs for one serving of this classic tuna noodle casserole is just 6g.

So let’s talk about the other ingredients.

Classic high carb tuna noodle casserole is ridiculously easy to make. All you need are egg noodles, canned tuna, frozen peas and cream of mushroom soup. Maybe some crumbled up potato chips for a fun topping. But we are on a low carb diet, you and I, so nothing is ever that simple.

No, instead of four ingredients, we’ve got about twelve.

I say about, because you’ve got one optional ingredient: peas. If you want to make an exact replica of classic tuna noodle casserole, you need to have a few peas, but they aren’t so low carb friendly, unfortunately. So if you leave them out, you’ll save yourself 2g net carbs per serving. Your call.

As to the rest of the ingredients, they are all readily available at the grocery store.

For the low carb cream of mushroom soup, you’ll need butter, garlic, red bell peppers, mushrooms, salt, pepper, chicken broth and heavy whipping cream. And to round out the ingredients, you’ll need several cans of tuna and some shredded cheddar cheese.

Once you’ve assembled your ingredients, this recipe actually comes together very quickly.

You can make this low carb tuna noodle casserole in about 50 minutes, so it’s a great throw together weeknight dinner. But it’s fancy enough to make when your persnickety boss unexpectedly comes over for dinner.

Just give your wife a wink, and welcome him into your happy home.
