Tuna Casserole with Potato Chips

When it comes to nostalgic meals, tuna noodle casserole ranks pretty high for me. I don’t remember being particularly excited about eating it as a kid, but these days the casserole brings up cozy feelings of being back home. I guess a creamy, cheesy casserole can do that to a girl! This Tuna Casserole with Potato Chips is now my ultimate comfort food!

While my mom made it with cream of mushroom soup, I knew I wanted to make it completely from scratch. So, I took the classic tun casserole and put a modern day spin on it. For one, I nixed the cream of mushroom soup and made my own creamy mushroom sauce. For a little extra effort, there’s a big payoff in flavor!

Next, I added a salty and crunchy topping with crushed potato chips. You really can’t go wrong with a potato chip topping, right? Last, I added some sharp white cheddar cheese. The cheese adds flavor and makes it a cheesy tuna noodle casserole.

I did, however, keep one important thing from the classic recipe, and that’s the egg noodles. I have seen recipes that use other types of pasta, but egg noodles are a family favorite in this casserole. They pair perfectly with the homemade creamy sauce.

This tuna noodle casserole is a total crowd pleaser and classic comfort food that your family will love!

Ingredients in Tuna Casserole With Potato Chips

There are many pantry staples in the ingredients for this classic casserole! It's also a great use for a can of tuna that you have in your cupboard that you've been wanting to use.

  • Egg Noodles - as mentioned, I love silky egg noodles, especially in this casserole!
  • Olive Oil
  • Butter
  • Vegetables - White onion or yellow onion are used in this recipe, along with sliced mushrooms. Cremini mushrooms or button mushrooms are what I typically use but if you have access to some fancy mushrooms, go for it!
  • Garlic Powder - I use garlic powder in this recipe to give it that garlicky flavor, but you could certainly add two cloves of minced fresh garlic, if you'd like!
  • Salt
  • Flour, Chicken Broth, and Milk - these are used for the homemade cream sauce in this tuna casserole. Chicken stock would also work in place of the broth.
  • Canned Tuna Fish Packed in Water - white tuna or light tuna both work.
  • White Cheddar Cheese
  • Potato Chips - Of course there are potato chips for the salty potato chip topping! I used wavy regular potato chips but any type of regular potato chips would work. Ritz crackers or cornflakes would also be great substitutes.

How to Make Homemade Tuna Noodle Casserole with Potato Chips

This tuna casserole recipe is made from scratch but that does not mean it is difficult to make. You can even prep this casserole in advance, to be baked at dinner time!

Cook the noodles. Cook the egg noodles according to the package directions.

Sauté the vegetables. While the water is coming to a boil for the pasta, heat the olive oil and butter over medium heat and then sauté the onion and mushrooms. Season them with salt and black pepper and cook until they are softened, about 7-10 minutes.

Make the cream sauce. Add the flour to the mushrooms and onions and stir to combine. Slowly add in the milk and broth, and whisk together to form a roux.

Add the noodles. Let the sauce cook for a few minutes so it can thicken up a bit, and then combine the roux with the cooked noodles, tuna, and some shredded white cheddar cheese.

Bake. Pour this mixture into a casserole dish, and top with more white cheddar cheese and crushed potato chips. Bake it until its bubbling and golden brown. Immediately dig in!

Serve. I recommend serving this hearty dish with a side salad or some roasted vegetables.

Storage. Store any leftover tuna casserole in an airtight container in the fridge for 2-3 days.

Tuna Noodle Casserole Questions

  • Can I use different noodles? Sure! I love the texture of egg noodles but other shapes would work, too.
  • Can I omit the mushrooms? If you must 🙂 You could use bell pepper or some frozen peas, instead, if you like.
  • Can yellow cheddar cheese be used instead of white cheddar cheese? Yes that will work. I like to use white cheddar to keep the look of traditional tuna noodle casserole but it can be tricky to find sometimes.
  • Can this be prepped in advance? Yes! You can assemble the casserole up to the step of baking. Simply cover the baking dish with plastic wrap, aluminum foil, or the casserole dish lid, and refrigerate until you're ready to bake. I would add 10 minutes to the baking time to account for the casserole starting from a colder temperature. Check the casserole after 20 minutes to make sure the potato chips aren't becoming too brown.
