What is Old Fashioned Tuna Casserole?

Old Fashioned Tuna Casserole is the kind of dish that feels like it came straight outta Grandma’s kitchen—and that’s exactly why we love it. At its core, it’s a comforting baked dish made from egg noodles, canned tuna, a creamy sauce (think mayo meets mushroom soup), and peas, all crowned with a crunchy cracker topping. The whole thing gets baked to golden, bubbly perfection, and it hits that sweet spot between rich and comforting without being overly heavy.

This recipe in particular leans into those nostalgic flavors while making a few tasty upgrades—like white cheddar cheese and parmesan in the topping. It’s easy to toss together, totally kid-approved, and adaptable if you’re in a “clean out the fridge” kind of mood. Got leftover veggies? Throw ‘em in. Don’t love tuna? Sub in canned chicken. That’s the beauty of this old-school favorite—it works with you, not against you.

Instructions to Make Old Fashioned Tuna Casserole

Let’s walk through how to make Old Fashioned Tuna Casserole step by step—no guesswork, no stress. This process is super approachable, even if you’re working with a clingy toddler on your hip or a hungry crowd breathing down your neck. Each step is packed with flavor, texture, and kitchen confidence boosters, so grab that apron and let’s get cooking!

Step 1: Boil the Egg Noodles (But Don’t Go Overboard)

Start by bringing a large pot of salted water to a boil. Add 3 cups of dry egg noodles and cook them one minute shy of al dente—you want them tender with a little bite, because they’ll continue cooking in the oven later. Drain them well and set aside. Overcooked noodles can turn mushy in the casserole, and nobody wants that. For more advice on pasta doneness, check out our Easy Chicken Tetrazzini where timing the pasta is just as important.

Step by step tip: After draining, toss noodles with a splash of olive oil to prevent sticking while you prep the rest.

Step 2: Make the Buttery Cracker Topping

While the noodles are cooling off, grab a small mixing bowl and make the topping that takes this dish over the top. Crush one sleeve of Ritz crackers (you can do this in a zip-top bag with a rolling pin—very satisfying), then stir in 1/3 cup of grated parmesan and 2 tablespoons of melted butter. Mix until everything’s coated and a little clumpy. Set it aside.

Step by step note: No Ritz? No problem. Try crushed potato chips, panko, or even buttered breadcrumbs. We’ve got more ideas in our Easy Chicken Parmesan Casserole that also uses a crunchy topping twist.

Step 3: Whip Up the Creamy Sauce

In another small bowl, whisk together 1 can of cream of mushroom (or celery) soup, ¾ cup of mayo, and 1 cup of milk. Whisk until smooth. This simple sauce gives the casserole its signature creamy comfort—and it binds everything together like a hug in a baking dish.

Step by step tip: Want a lighter twist? Sub part of the mayo with Greek yogurt or sour cream. You’ll find more substitution ideas in our Healthy Hobo Casserole.

Step 4: Sauté the Aromatics

Heat 2 tablespoons of butter in a large 12-inch oven-safe skillet over medium heat. Once melted, add 2 diced celery stalks and 1 cup of diced onion. Sauté for about 5 minutes, or until the veggies are softened and fragrant. Then add 3 minced garlic cloves and stir for another minute.

Step by step detail: Don’t rush this part—the aroma alone is worth the time. This step builds the base flavor for the entire dish.

Step 5: Combine Everything in the Skillet

Remove the skillet from heat. Now stir in your creamy sauce mixture, 1 drained can of tuna (go for solid white albacore if you want a cleaner taste), 2 cups of shredded white cheddar cheese, the cooked noodles, and 1½ cups of frozen peas. Stir it all together until well combined and evenly coated.

Step by step tip: Be gentle with the noodles. You want everything mixed well, but not broken or smushed. Think “comforting casserole,” not “tuna mash.”

Step 6: Top It Off and Get Ready to Bake

Sprinkle that golden, buttery cracker topping evenly across the top of the casserole. Make sure to cover the entire surface—this is your crispy crown!

Step by step insight: Press the topping down just slightly with the back of your spoon to help it stay put and crisp up while baking.

Step 7: Bake to Golden Bubbly Perfection

Preheat your oven to 400°F (if you haven’t already). Pop the skillet into the oven and bake for 20–25 minutes, or until the top is golden brown and the casserole is hot and bubbly. You’ll know it’s ready when the cheese is melted and the edges are gently sizzling.

No oven-safe skillet? No worries. Just transfer the mixture to a greased 9×13 casserole dish and proceed with the same bake time.

Step 8: Let It Cool and Serve

Once out of the oven, let the casserole cool for about 5 minutes before serving. This gives the sauce a chance to settle and thicken slightly—plus, no one likes a burnt tongue from diving in too fast.

Step by step serving idea: Pair it with a simple green salad or some roasted veggies like those in our Chicken and Potato Casserole for a full, hearty dinner.

What to Serve with Old Fashioned Tuna Casserole

Old Fashioned Tuna Casserole plays well with others, so you’ve got options. A crisp green salad with a tangy vinaigrette cuts the richness and adds a pop of freshness. Garlic bread? Always a good move. If you want to round it out into a full comfort-food feast, serve it with roasted veggies like carrots or broccoli. Want to stay in cozy casserole territory? You’ll love pairing it with our Cheesy Vegetable Casserole for a veggie-forward sidekick. And for a retro potluck vibe, a jiggly fruit salad or pickles on the side hits all the nostalgic notes. It’s like Sunday supper at Grandma’s, minus the “no elbows on the table” rule.

Key Tips for Making Old Fashioned Tuna Casserole

1. Don’t overcook the noodles—seriously, they’ll keep cooking in the oven and you don’t want mush.
2. Use good quality tuna. It really makes a difference in flavor. Skip the mystery meat and go for solid white albacore if you can.
3. Add-ins welcome! Mushrooms, corn, or even chopped spinach play well here.
4. No oven-safe skillet? Transfer everything to a 9×13 baking dish before adding the topping.
5. Cracker swap: No Ritz? Try crushed potato chips or panko for a similar crunch.
6. Cheese tip: Don’t skip the white cheddar—it adds sharpness that balances the creamy base.
7. Make ahead: Assemble it up to a day in advance, cover and refrigerate, then bake when ready.

Storage and Reheating Tips for Old Fashioned Tuna Casserole

Got leftovers? Lucky you! Old Fashioned Tuna Casserole stores like a champ. Just cover the cooled casserole with foil or pop it in an airtight container. It’ll keep in the fridge for 3–4 days. To reheat, microwave single portions for 1–2 minutes or reheat the whole dish in the oven at 350°F until warmed through. If it looks a little dry, stir in a splash of milk before reheating to bring back that creamy magic. Freezing? Totally doable. Wrap it tightly in plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the fridge before baking. Perfect for meal prepping or feeding your future tired self.
