Tuna Zoodle Casserole (Whole30, Paleo, Keto)

MY HUSBAND LOVES TUNA NOODLE CASSEROLE. I HAVE TO ADMIT, I DIDN’T EVEN KNOW WHAT IT WAS UNTIL I MET HIM.

It’s just one of those things, like many American comfort food staples, we didn’t have in my house. My parents are Cuban, they immigrated to this country in the eighties. While I don’t think my moms cooking was very representative of Cuban cooking, she had her own style, it definitely didn’t include casseroles.

I LIKE TO THINK OF MY MOTHER AS MY GREATEST TEACHER.

I inherited her passion for cooking and some of her skill too. My style has evolved from mimicking hers to include dishes from all over. I greatly attribute that knowledge for my different jobs in kitchens, to moving around with the military, to loving to go out to dinner and of course, to traveling!

The first time I made tuna noodle casserole for my husband I was vegan. Ha! Yes… I used to be vegan. Well, by the time him and I were serious I had added sea life back in to my diet. So I made him this dairy free, heavy, gluten-full tuna casserole with lots of dairy free franken-food cheese. He ate it. Bless his heart.

Today I wanted to create something SUPER easy to make. A budget friendly, time friendly, low carb meal that fit in with my macros. I wanted something warm. It’s been a crazy few days and this girl needs all the comfort she can get.

THIS. THIS HAS ALL OF THAT. AND IT’S TASTY AF!

YOU WILL NEED TO MAKE CASHEW CREAM FOR THIS.

But seriously… if you’re not already making my cashew creamer for your coffee and other cooking needs you are missing out! This stuff is thick, creamy,and thickens when warmed.

It’s amazing.

How to make it:

Soak 2 cups whole raw cashews. Submerged in water with a pinch of salt for at least 4 hours or overnight.

Drain. Rinse.

Place soaked cashews in blender. Add in 2.5 cups filtered water. Blend on high until silky smooth

Store in a jar in the fridge up to a week. Boom.

Variations

To make this NUT FREE:

You can make a cream sauce by using sun butter or tahini. Mix 2 tablespoons with 1/2 cup water until smooth. 

Or you can use cauliflower alfredo, recipe HERE. 

To make this EGG-FREE: 

Skip the mayo, mix 1 tablespoon of gelatin with cream sauce or use AIP cheese, recipe HERE.  

Use a 5×7 or 8×8 baking dish. Double the recipe for a full size casserole!

  14. Spread this mix over the top of the casserole.
  15. Sprinkle lightly with salt.

  1. I love this recipe! I use broccoli rice on top to save time and broil for 3-5 mins to give it a little more crunch. Thank you for sharing. Also, how many servings is this recipe? I see your nutritional info but can’t find how many servings. Thank you!

  2. I made this tonight, It was amazing! I did saute the mushrooms, onions and garlic prior to adding them to the cassserole. Also, I added a bit of cheddar cheese. The result was the best tuna casserole I have ever had. Thank you

  3. Hi! I made this tonight and it came out truly amazing!!! Seriously my new favorite recipe–thank you so much! 🙂 I did follow Vicki’s lead (Commenter above) and sauté the mushrooms/onions/garlic together before adding them to the casserole and also added 1/4 cup shredded sharp cheddar on Top right before baking. This is such a fantastic and healthy twist on an old favorite. I will definitely be making it again and look forward to trying your other recipes!

  4. Good lord this recipe is AMAZING! Im not a fan of hot tuna so i used rotisserie chicken. When i made my cashew cream, i also threw in Two cloves of garlic and a couple shakes of dry mustard…so good!
