Growing up, I ate tuna casserole often. It’s probably one of my favorite comfort dinners during the winter season and thankfully it’s also super easy to keto-fy!
Now, tuna casserole is usually made with some carby vegetables such as peas. So for this recipe, I swapped those out for some keto-friendly veggies like mushrooms and a small amount of carrots. Instead of pasta noodles I used shirataki noodles, but zucchini keto noodles are also a great alternative.
The great thing about this recipe it is incredibly easy to make and preparation time takes almost no time at all. Later on, you can freeze this casserole and save it for later or take it to work!
