Low Carb and Keto tuna casserole

 

Keto Tuna Casserole

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 6 net carbs per serving – which for a dinner is not bad.  Anything under 10 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.  

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.

Ingredient Choices

Veggies

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! 

If you are at all concerned with eating veggies, carb count and keto, please take a moment to read about Keto And Veggies: Are Veggies Optional?

Cheese

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!

Mayo

I happen to have vegan mayo in the fridge and it was acceptable to use.  Regular mayo is fine too so long as the ingredient list is satisfactory and the carb count is reasonable.  I generally use an avocado-based mayo – so yummy!

Topping

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.

Before being baked: you can see that the toasted almond flour already has a slight golden hue.

After baking: Now you can see a bit deeper golden color!

HOT KETO RECIPE – Keto Beef Casserole

Kitchen Essentials

 

At a minimum, you’ll need a frying pan and 8x4 glass baking dish.  If you don’t have glass, it should be fine, but I really like to use glass because I find that things cook better in a glass. pan 

 

Tips

 

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!
