This tuna noodle casserole is the best… it’s my mom and grandma’s recipe! A creamy, cheesy sauce coats egg noodles, dotted with green peas and flake tuna, topped with melty cheesy and buttery breadcrumbs. This classic recipe is rich and creamy, made from scratch but so quick and easy to throw together. No canned soups here! A true budget meal but indulgent at the same time.
Why You’ll Love This Recipe
- Growing up, we ate my mom’s tuna noodle casserole recipe all the time, and it’s still one of my favorites. Mom’s been making it for over 40 years, and her mom made it for her when she was a kid. As Catholics, they had it every Friday (It was that or fish sticks, ha!).
- Even now, whenever I need a quick and cheap comfort food meal from the pantry and freezer, this one comes to mind. I admit, it’s not totally the casserole from my childhood. I upgraded it to be super creamy and saucy, with some veggies.
- This recipe doesn’t use any canned soups like most tuna noodle casserole recipes. No cream of mushroom – just real roux, milk, and cheese!
Tuna – You can use tuna in water or oil, whichever you prefer. Water-packed tuna will be a little lighter when it comes to calories and fat. If you want to double up on the amount of tuna used in this recipe, you absolutely can!
Noodles – Egg noodles are the classic noodle-of-choice when it comes to tuna noodle casserole, but you can use any type of noodle you like best. If you’re looking for a noodle-less option, check out our recipe for Whole30 Tuna Zoodle Casserole (Paleo, Dairy Free)!
- For a gluten free version, substitute the egg noodles with an equal weight of gluten free noodles. Use the same amount of gluten free flour.
- You can use gluten free breadcrumbs if you can find them, but if not, it’s super easy to make some out of gluten free bread. Or just leave them out! They are totally optional.
- If you don’t have peas or just don’t like them, you can leave them out. You can also sub basically any other veggie you like in their place. Chopped broccoli? Asparagus? Spinach? Corn? All great options.
- Since the noodles get cooked twice (once on the stove, again in the oven) you want to make sure they’re just barely cooked when you take them off the stovetop. This will keep them from overcooking in the oven.
