Ah, the tuna noodle casserole. I dreaded it as a child. Not that I didn’t like tuna…or pasta…or even peas. I just didn’t like them together. And truth be told, my mom wasn’t much of a casserole maker. But I am! I’m a huge fan of casseroles, but had yet to find tuna noodle casserole recipe I liked. So I made my own!
I am trying to come up with meatless meals that are also high fiber and fit my high protein diet for weight loss and better aging. The benefit of a high protein diet as we age is that it helps us build or maintain muscle and stay strong. As the only woman in a house full of men, high protein just works for us all.
Best Healthy Tuna Noodle Casserole Recipe
I’m not going to lie, this particular recipe does not have the Ritz cracker crumble topping I remember as a child, but it’s still packed with delicious flavor. This one is more “elevated” if you will. It’s also super easy to make. The prep time is only 10 minutes and there will be enough for leftovers…well maybe.

Note: I prefer using chickpea pasta because it’s higher in protein, lower carb and a gluten- free alternative to traditional pasta. I also use gluten-free flour and almond milk because that’s how we roll. It’s delicious any way you decide to make it and if you’re really dying for the Ritz cracker topping, of course have at it.
