Tuna Noodle Potato Chip Casserole

I’m from the Midwest and guess what? We LOVE casseroles. Whether it’s tater tot casserole, spaghetti pizza style or tuna noodle potato chip casserole, we were always pumped about casserole night.

And if you’re not sure what any of these casseroles are, hang tight because I have tuna noodle casserole RIGHT HERE, RIGHT NOW, and the spaghetti pizza style and tater tot casserole are comin’ in hot this fall and winter.

If you try all three, you’ll basically be reliving my childhood with me, and I’m here for it.

Finished Tuna Noodle Potato Chip Casserole recipe

This recipe is better than the original

OG tuna noodle potato chip casserole is made with egg noodles, tuna, peas, a ‘sauce’ made with cream of mushroom soup and is topped with crushed potato chips.

My new and improved tuna noodle casserole is made with many of those traditional ingredients, but instead of “cream of” soup, I made the sauce from scratch. And it’s still insanely simple and easy to make, but it’s SO MUCH MORE delicious.

It starts with butter, onion and garlic, a roux (flour added to the butter to thicken), stock and milk, my (not-so) secret seasonings and is finished with Parmesan cheese.

Then, you stir in peas, tuna and a squeeze of fresh lemon juice if you’re feeling sassy. Um, yum.

Learn how to make tuna noodle casserole with potato chip topping – from scratch!

And THE BEST PART is the potato chip topping, which is just…. potato chips. What else could you possibly need to make this so freaking delicious?

Crispy, salty potato chips are crushed up and sprinkled on top, then baked until the sauce is bubbly and the chips are even crispier.

It’s just amazing. And nostalgic. And comforting.

You need it, I need it.
