Creamy Slow Cooker Tuna Noodle Casserole

Thanks for sharing!

It seems like nearly everyone has enjoyed a serving of good old-fashioned Tuna Noodle Casserole at some point in their life. Probably because it is inexpensive, easy to make, and completely satisfying. I know that I have made my fair share of this tasty casserole through the years. 

Traditionally, tuna noodle casserole is baked in the oven, however, I recently ventured out and made a (gluten-free) Creamy Slow Cooker Tuna Noodle Casserole version.  Let me show you how I made it.

First, start by cooking your favorite pasta noodles just until they start to soften. Since this particular tuna noodle casserole is made in a slow cooker we certainly do not want to overcook the pasta.

Note: For a gluten-free version be sure to use gluten-free pasta. For an even healthier version, I personally like gluten-free chickpea shells (as pictured in this post).


Next, drain the pasta and place it right back into the pan it was cooked in. 

Extra Ingredients

Now stir in Alfredo sauce, thawed sweet peas, and shredded Cheddar-Jack cheese.

Note: For a gluten-free version be sure to use gluten-free Alfredo sauce.


Naturally, tuna is a key ingredient in Creamy Slow Cooker Tuna Noodle Casserole so go ahead and gently fold the tuna in.

Slow Cooker

The mixture is now ready to pour into a lightly greased slow cooker.


A topping is created by combining panko bread crumbs, Parmesan cheese, dried or fresh parsley, and garlic powder.

Note: for a gluten-free version be sure to use gluten-free gluten-free panko bread crumbs and Parmesan cheese.

Ready to cook!

Sprinkle the topping evenly over the tuna noodle casserole, cover, and turn the slow cooker on low for 3 hours. 

Full Disclosure

My daughter and son-in-law are currently in the process of renovating a home. Because their new kitchen is under construction at this time, I took this Creamy Slow Cooker Tuna Noodle Casserole to them. Once I arrived I plugged the slow cooker into an outlet in their garage, turned it on, walked away and went in and helped them work on the house. When lunchtime rolled around a few hours later, the tuna noodle casserole was bubbly hot and ready to eat. 


Serve Creamy Slow Cooker Tuna Noodle Casserole along with a side salad, grilled asparagus, or your favorite vegetable.
