This classic tuna noodle casserole has been in my family forever and ever. My grandma made it for my mom, and my mom has been making it for over 40 years; now it’s one of my fave comfort-food dinners. Made with tender egg noodles, flaky tuna, a rich, creamy cheese sauce, and no canned soup in sight, it’s finished with buttery breadcrumbs for an easy, budget-friendly casserole that only takes 30 minutes to bake!
See recipe card below for full list of measurements, ingredients, and instructions.
Why This Is Your New Favorite Casserole
- While tons of tuna noodle casserole recipes have canned cream of mushroom soup, I made this with a quick homemade cheese sauce made of roux, milk, and cheddar. It only takes a few extra minutes, and the payoff is a casserole that’s richer, creamier, and full of real cheesy flavor.
- I looove my family recipe, but definitely made some changes to amp up the nutrition and bring out the cheesy flavor and creaminess. I kept everything I love about traditional tuna noodle casserole, but added that rich homemade cheese sauce and vegetables for more texture and flavor.
- There are times when I like quick meals without sacrificing taste, and this creamy casserole delivers: it takes 30 minutes to cook, uses simple pantry and freezer staples, and I can throw it together any time I feel like it without a side quest to the grocery store. It’s a complete meal that doesn’t need many sides either — a simple salad or steamed or roasted vegetables go well!
What I Learned Testing This Recipe
- I’ve found that freshly shredded cheddar melts SOO much better than pre-shredded cheese. It takes a few extra minutes to grate it yourself, but the sauce turns out smoother, creamier, and much less grainy.
- It’s better to slightly undercook the egg noodles since they’ll continue cooking in the oven. I take them off the stove just before they’re fully done, which keeps them tender and prevents the casserole from drying out.
- One thing that really helps is letting the milk and cheese come to room temperature before you start. I also take the saucepan off the heat before stirring them in. That helps keep the sauce silky instead of separating.
Ingredients
Egg noodles – I always use wide egg noodles because they hold onto the creamy sauce and give this casserole its classic texture. If you don’t have egg noodles, rotini, fusilli, or medium shells work well too.
Butter and all-purpose flour – These create a simple roux, which thickens the homemade cheese sauce without relying on canned cream of mushroom soup. For a gluten-free version, swap in your favorite 1:1 gluten-free flour.
Whole milk – I recommend whole milk for the richest, creamiest sauce. Don’t use 2% here because the sauce just won’t be quite as rich, and we want it super creamy!
Cheddar cheese – I prefer shredding cheddar from a block, as it melts much more smoothly than pre-shredded cheese and gives the sauce the creamiest texture. Sharp cheddar adds extra flavor, but mild or medium cheddar is a great option too.
Canned tuna – I typically use chunk light tuna packed in water, but albacore works too if you prefer larger, meatier flakes. Make sure to drain it well before adding it to the sauce.
Frozen peas – I love the pop of sweetness and color frozen peas add, but it’s easy to leave them out. You can also add other veggies, like broccoli, spinach, asparagus, or corn; they’re some of my faves you could rotate.
Breadcrumbs – Plain breadcrumbs are best because they soak up the butter nicely. You could also use Italian-seasoned breadcrumbs. They’d add a little extra garlic and herb flavor. Also, if you’re dealing with allergies, gluten-free breadcrumbs are an easy substitute!
How to Make Tuna Noodle Casserole
Make the roux – Start by melting the butter in a saucepan over low heat, then whisk in the flour until smooth. Continue whisking for about 1 minute, until the roux turns lightly golden and begins to bubble.
Whisk in the milk – Next, quickly remove the saucepan from the heat and slowly whisk in the milk, adding a little at a time to keep the sauce smooth. Return the pan to medium heat and whisk constantly, until the sauce thickens (it should bubble).
Add the cheese – Take the saucepan off the heat, then stir in the cheddar cheese and all seasonings until the cheese has completely melted into the sauce.
Cook the noodles – Bring a large pot of salted water to a boil, cook the egg noodles until they’re just shy of al dente, using the shortest cooking time listed on the package. Drain them well and transfer them to your casserole dish.
Assemble the casserole – Add the cooked egg noodles to a casserole dish, then pour the cheese sauce over the top. Add the drained tuna and frozen peas.
Bake – Gently fold everything together until the noodles, tuna, and peas are evenly coated in the creamy cheese sauce. Spread the mixture into an even layer, then bake at 350°F for 15 minutes while you prepare the breadcrumb topping.
Add the breadcrumb topping – After 15 minutes of baking, remove the casserole from the oven, sprinkle the remaining cheddar cheese evenly over the top, then add the buttery breadcrumbs. Return it to the oven and bake for 5 minutes more, until the cheese is melted and bubbly and the breadcrumbs are lightly golden.
Serve – Remove the casserole from the oven and let it rest for 3 to 5 minutes before serving so the sauce has a chance to thicken. Sprinkle fresh parsley on top and serve.
Serving and Storage Suggestions
This is such an easy tuna noodle casserole recipe, right?! When it comes to sides with this dish, I like something fresh and crisp to balance the rich, creamy sauce. A simple green salad, roasted or grilled broccoli, air-fried asparagus, or roasted Brussels sprouts are my top picks. Another fave is warm dinner rolls or garlic bread, because they soak up the homemade creamy cheese sauce sooo nicely!
Leftovers keep well in the fridge for up to 3 days. Reheat in an oven until warmed through, or microwave individual portions in short bursts, stirring once or twice if needed. You don’t want to zap it too long in the microwave and end up with dried-out noodles!
One of the reasons this casserole has survived in my Catholic family over the generations is because you can freeze this, a practice I still do today! Just add a splash of milk when reheating to bring back that creamy consistency.

Frequently Asked Questions
No doubt this sucks when it happens! A watery casserole is usually caused by overcooked noodles or excess moisture from the peas or tuna. Cook the noodles just until al dente, drain the tuna super well, and let the casserole definitely let it rest for 5 to 10 minutes after baking so the sauce has time to thicken.
For sure, you can assemble it 24 hours in advance (just cover it tightly in the fridge) When you’re ready to make dinner, let it sit at room temperature for 20 to 30 minutes, and then bake as directed.
When the filling is hot and bubbly around the edges and the topping is golden brown. I advise using an instant-read thermometer and inserting it into the center; the temperatures should be 165°F.

Cheddar Cheese: Instead of using prepackaged shredded cheese, I recommend buying a block of fresh cheddar and shredding it yourself. Prepackaged shredded and grated cheeses typically contain starches and other fillers to prevent clumping, but they can make the cheese grainy and keep it from melting like it should.
Dairy Products: To ensure your dairy products don’t seize, separate, or curdle, bring them to room temperature before starting this recipe. Remove the saucepan from direct heat before incorporating any dairy ingredients, to prevent heating them too quickly.
Make it Gluten Free: Substitute egg noodles with the same amount of gluten-free noodles. Use gluten-free all-purpose flour instead of regular flour. Use gluten-free breadcrumbs, make some out of gluten free bread, or omit the breadcrumb topping entirely.

Easy and delicious.
So glad you enjoyed it, Nancy!
Can I prepare in advance and bake when needed? Thanks!
Yes! For freezing, just let it cool completely before you put it in the freezer. The breadcrumb topping might not be be as crispy after freezing and thawing, but the rest of it should taste fine!
I make my casserole with roux but don’t use cheese. However, after I bake I feel like it has list all the sauce, very dry. Any ideas?
Hi, Barbara! The 1 cup of cheese is a significant component of the sauce, adding moisture and creaminess to the dish. By omitting the cheese entirely, you’re changing the sauce substantially. I encourage you to try it as written!

Loved it, have been trying several different TNC recipes and this is…[drumroll] the Winner!!! I did add mayo because I’m a Dukes addict🫣 but other than that followed to a T..oh and I used monterrey jack cheese..but i did shred it myself!(carrots were my veggie of choice) and it was Ab Fab! Gonna try some of your other casserole recipes ❤️
Thank you so much, Katherine! I’ll be sure your compliments are passed on to Cheryl’s mom – she’ll be thrilled to know you enjoyed it and made it your own!
So delicious! I tried to minimize my swaps. I only had 2 cups of milk so I used 1/2 cup heavy cream as well. I make my own breadcrumbs but they worked amazing with this. I used a Cajun seasoned cheddar for the 1/2 cup that goes on top and it gave it a slight kick without spicing it up to much. And I added some frozen broccoli and cauliflower. Needs about 5 extra minutes with broccoli and cauliflower or maybe defrost them a bit before adding, but it was so good. That cheese sauce came out so amazing and overall delicious. Picky boyfriend approved!
Your variations all sound amazing, Jen! I’m making a note right now to try it with a Cajun cheddar next time. Thank you so much for sharing this with us!
very easy, better than most.
So glad you enjoyed it, Troy!
I absolutely love this!! The panko and salt/butter mixture took it to a different level!!!! Thank you for sharing.
The panko makes it soo good!! So glad you enjoyed it, Emma! 🙂
Can you feeeze it? I know some dishes you shouldn’t.
You can! Just let it cool completely before you put it in the freezer. The breadcrumb topping won’t be as crispy after freezing and thawing, but the dish overall should taste just fine.
WOW! Thank you so much Cheryl! I just made this recipe and my husband was super happy with the results and told me “keep this one in your arsenal!” The roux was so creamy and the most perfect one I’ve ever made (I did use extra creamy oat milk instead of whole milk for the 1st time) and I used “Carba-nada” noodles. Besides those two substitutions, I followed the full recipe.
SO happy you and your husband enjoyed this one, Sandra! Thanks for giving it a try, and for letting us know about those successful swaps!
