Keto Tuna Casserole
**** UPDATED RECIPE 6/18 *****
All my older kids were not home for dinner and it was just my 5-year-old, hubby and I. Didn’t really feel like grocery shopping and I wanted to make something I had on hand. I had never made a keto tuna casserole so it was time I gave it a shot.
I gathered up the ingredients I wanted to use and off I went. The only thing I didn’t have but wish I did was a bell pepper. So feel free to add that in.
This is about 2 net carbs per serving – which is pretty darn good for a low carb pasta style dinner! Anything under 8 for dinner is what I shoot for. Breakfast is minimal since I just have my keto collagen protein shake and lunch is normally almost zero carbs. I do have a snack each day worth about 5.

What I love most about dishes like this is that they are GREAT for leftover lunches. Check out this beautiful and flavor filled keto chicken salad and eat it ANYTIME! There are just some dishes that taste great anytime, and BOTH these dishes fit that bill!
For leftovers, I enjoyed this keto tuna casserole with my favorite keto buns and made an open face sandwich! You can certainly eat it on its own as well.
Tuna Casserole Recipe Ingredients
I LOVE veggies! As I said, I only wish I had a bell pepper as that would have made this even more perfect! Celery and onion, though, were the perfect addition.
Do you shy away from veggies because of keto? PLEASE SAY NO!

I opted for goat cheese instead of regular cheese because the lactose content is lower and we are really trying to limit dairy, specifically lactose. Goat cheese is so yummy, anyway. It provides this slight tangy taste that just makes everything better!
I chose to use a zero carb REAL mayonnaise. I’ve found that the real mayo is less in carbs than vegan and avocado.
Low Carb Tuna Casserole Toppings
I really wanted a slightly crunchy top and I didn’t feel like just putting regular almond flour on top would do it. As I’ve mentioned before, I’m not a big fan of eggs in casseroles. So, I also didn’t want to mix any eggs in here since it is fully cooked before even entering the oven and I wanted to keep it that way.
I decided to toast the almond flour first to give it that great toasted flavor before even being baked! 15-20 minutes is a perfect time frame for this toasted almond flour to combine with the top of keto tuna casserole and get golden and crunchy.
If you don’t know how to toast almond flour, be sure to check out my post on, well, how to make toasted almond flour!
Additionally, I add crumbled goat cheese as part of the topping. This really adds a ton of flavor and “spices” up the top!
Before being baked: you can see that the toasted almond flour already has a slight golden hue.
These 2 pictures were the original recipe that did not include goat cheese crumbles on top!!
After baking: Now you can see a bit deeper golden color!
HOT KETO RECIPE – Keto Beef Casserole
Now, a few pictures that are shown here are the 1/2 batch version. This version basically splits the recipe in half and does not have goat cheese on top! Below is what that version looks like if you want to make less!
Using 2 knives or 2 forks when combing the tuna with the goat cheese and mayo is really helpful. Tuna from a can often stick together in big chunks and you really want to break them up.
This dinner goes great with keto buns – so whip up a batch of those as well!
