It was never the intention to make low carb casserole recipes. But here is how this low carb version came about.

How do you make your cheesy tuna casserole?

I texted my mom.

I don’t make a cheesy tuna casserole

She replied.

I thought you did with peas or something? I swear I had it back home.

No reply from Mother.

So, I looked up Tuna Casserole.

Sure enough, there it was in several different versions, but with commonalities: cream of mushroom soup, mushrooms, small amount of peas, chunks of tuna, creamy cheesy sauce of some sort and pasta, usually via egg noodles.

Ah, yes! The Midwest comfort food at its finest.

I was craving this great recipe, but I had no idea why. Costco now sells the Wild Planet Wild Albacore Tuna, so I had that on hand.

Maybe that was the reason.

Or maybe it was the mayo.

(I admit, in a really (even more) bizarre way, I was craving mayo with my tuna, but not chunky, nasty-ingredient-filled mayo.)

Or maybe I was just missing Minnesota, since I came to find out afterwards that yes, in fact, it is a Minnesota “hot dish.”

In any case, I made this Midwest Cheesy Tuna Casserole my own, turning it into good comfort food that can work while healing!

Dairy Free Recipe

It’s Gutsy approved, and even friendly for those with SIBO and/or who need to remain low-FODMAP.

Yeah, yeah, it’s Paleo and fits under low carb recipes in case you need to follow a low carb diet for any reason.

But most importantly….it’s so dang good!

It starts with the cans of tuna and a homemade mayo mixture.

The mixture is then added to a few other simple ingredients like….

Spaghetti Squash

Coconut Milk (Use the coconut milk of your choice. Click the image below to learn a little more about these.)

Nutritional Yeast (only the best thing since raw cheese)

You simply put it together, and mix by hand (<- not bare hands, though. Use a fork, spoon or spork.)

Notes on the ingredients for this healthy tuna casserole

1. Egg yolks are filled with healthy fats. They are used in this recipe to make the “mayo.”
2. Use olive oil because it’s an oil that can withstand high heat.
3. I prefer the Wild Planet Wild Albacore Tuna brand, but essentially you need 2 x 5-ounce cans tuna. Another thing to keep in mind is that if you do choose the Wild Planet brand it does not need to be drained tuna. You want all the fatty acids possible.
4. Speaking of tuna, I am a huge fan of tuna, but if you’re not, you could also use high-quality chunks of chicken instead.
5. Spaghetti squash replaces the traditional noodles, which is the primary way this turns to a low carb tuna recipe. And while I have not made the recipe with any other type of noodle, here are 2 others you could consider if you don’t want to use spaghetti squash: shirataki noodles or zucchini noodles.
6. The creamy sauce is mainly due to the coconut milk; the coconut milk replaces heavy cream to make this a dairy-free recipe. For this reason, I’d choose a high-fat coconut milk. You could also choose full-fat cashew milk, almond milk, or even walnut milk.
7. And again, in order to remain dairy free, we skip the traditional cheddar cheese, cream cheese, or the like. Instead, I opted for Nutritional Yeast, which also contains that Vitamin B for those of you who need extra.
8. The next time I make this, here are some other things I might consider:
9. Adding in green beans. Remember, the original uses peas, so this might be a fun, low-carb swap.
10. Using fresh herbs, sprinkled about the recipe. Herbs are some of my favorite things for increasing overall gut health!
11. Spice it up by adding in a little bit of cayenne pepper or regular black pepper.

Casserole Dish

I used a simple baking dish to bake it in. I have had these same baking dishes since we got married.

We got a whole set of awesome baking dishes for our wedding from Williams Sonoma. You’ll find it HERE.

Anyways, all that’s left it to bake it.

Well, bake it. Cheese it some more. Bake it some more.

And dig in, which is the best part.
