Ingredients
For the Casserole
- 12 oz (340g) wide egg noodles
- 2 cans (5 oz / 142g each) tuna in water, drained well
- 1 cup frozen peas (no need to thaw)
- 1 cup shredded sharp cheddar cheese, divided
- 1 small yellow onion, finely diced
- 2 stalks celery, finely diced
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup chicken or vegetable broth
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 3/4 teaspoon salt, plus more for pasta water
- 1/4 teaspoon black pepper

Ingredient Notes and Substitutions
Tuna: Tuna packed in water gives a cleaner flavor in a creamy sauce. Oil-packed works too; just drain it thoroughly and pat dry with a paper towel or the sauce can feel greasy.
Egg noodles: Wide egg noodles are the classic choice and hold up well in the oven without going mushy. Rotini or medium shells work as a backup.
Milk: Whole milk gives the creamiest sauce. 2% is fine. Avoid skim; the sauce will be thin.
Peas: Frozen peas go in straight from the freezer. Canned peas (drained) work in a pinch.
Cheese: Sharp cheddar gives flavor; medium cheddar gives melt. A mix of both is the sweet spot.
[SUBSTITUTION: For a dairy-free version, use unsweetened oat milk in place of whole milk and a dairy-free cheddar-style shred. The sauce will be slightly less thick, so let it simmer an extra minute or two before combining.]
Equipment You’ll Need
- Large pot for boiling noodles
- Large oven-safe skillet or 9×13 inch baking dish
- Medium saucepan for the cream sauce
- Colander
If you have an oven-safe skillet (cast iron or stainless), you can make the sauce directly in it and transfer everything to the oven without a second dish. That saves cleanup and helps the bottom of the casserole get a slight crisp.
Before You Start
Preheat your oven to 375°F (190°C). Dice the onion and celery, drain the tuna thoroughly (press it gently against the side of the can with the lid, then transfer to a bowl and break it into flakes), and shred your cheese if buying block cheese. Getting these done first makes the sauce step feel effortless.
Salt your pasta water generously. Under-salted noodles going into a creamy casserole end up tasting flat even with a well-seasoned sauce.
Step-by-Step Instructions
- Boil the noodles. Cook the egg noodles in a large pot of generously salted boiling water for 2 minutes less than the package directions. They’ll finish cooking in the oven, so pulling them early keeps them from going soft. Drain and set aside.
- Saute the aromatics. Melt 3 tablespoons of butter in a medium saucepan over medium heat. Add the diced onion and celery and cook for 4 to 5 minutes, stirring occasionally, until softened and translucent. You’re not trying to brown them; you just want the sharp raw edge gone.
- Build the roux. Sprinkle the flour over the softened vegetables and stir constantly for about 1 minute until the mixture looks like a pale, slightly grainy paste. This step cooks out the raw flour taste. Don’t rush it. [CHEF’S NOTE: A roux cooked for less than 60 seconds will leave your sauce with a faint floury aftertaste. Give it the full minute over medium heat, stirring the whole time, until it smells faintly nutty.]
- Add the liquid gradually. Pour in the broth slowly while whisking, then add the milk in a steady stream, whisking the whole time. Bring to a gentle simmer over medium heat, stirring frequently. The sauce will thicken within 3 to 4 minutes. It should coat the back of a spoon but not be gluey. Season with salt, pepper, garlic powder, onion powder, and the Dijon mustard.
- Melt in the cheese. Remove the saucepan from heat and stir in 3/4 cup of the shredded cheddar. Stir until it’s fully melted and the sauce is smooth. [IMPORTANT: Adding cheese to a sauce that’s still at full boil can cause it to break and turn grainy. Pulling the pan off heat first keeps the sauce creamy.]
- Combine everything. Add the drained noodles, flaked tuna, and frozen peas to the sauce. Fold gently until evenly coated. Taste for seasoning and adjust salt if needed. Transfer to a greased 9×13 inch baking dish if you aren’t using an oven-safe skillet.
- Top and bake. In a small bowl, stir together the breadcrumbs, melted butter, salt, and Parmesan if using. Scatter the remaining 1/4 cup of cheddar over the casserole, then distribute the breadcrumb mixture evenly on top. Bake uncovered at 375°F (190°C) for 18 to 20 minutes, until the topping is golden brown and the edges are bubbling.
- Rest before serving. Let the casserole sit for 5 minutes out of the oven before scooping. This lets the sauce set slightly so it serves cleanly rather than running.
Helpful Tips for the Best Result
Drain the tuna twice. Open the can, press the lid down firmly to squeeze out liquid, drain into the sink. Then transfer the tuna to a paper towel and gently press again. Excess water is the most common reason a casserole comes out watery rather than creamy.
Don’t skip the mustard. A teaspoon of Dijon doesn’t make the casserole taste like mustard; it brightens the whole sauce and rounds out the richness. It’s a background flavor that you’ll notice the absence of more than the presence.
Topping density matters. A thin scattering of breadcrumbs will toast but not give you real crunch. You want it to feel almost too thick when you spread it on; it settles during baking.
Variations Worth Trying
Add mushrooms: Slice 8 oz of cremini mushrooms and cook them down with the onion and celery until their liquid evaporates. They add an earthy depth that complements the tuna well.
Spicy version: Stir 1/2 teaspoon of red pepper flakes and a few dashes of hot sauce into the cream sauce before combining.
Extra veggie: Stir in 1/2 cup of frozen corn along with the peas, or fold in a handful of baby spinach right before baking.
Gluten-free: Use your preferred gluten-free pasta (rice-based holds up best), swap the all-purpose flour for a 1:1 gluten-free flour blend in the roux, and use gluten-free breadcrumbs or crushed rice crackers for the topping.
Storing, Freezing, and Reheating
Refrigerator: Cool completely, then store in an airtight container or cover the baking dish tightly with plastic wrap. Keeps well for up to 4 days.
Freezer: Tuna noodle casserole freezes reasonably well, though the noodles do soften slightly after freezing and thawing. If you plan to freeze it, slightly undercook the noodles even more than directed (3 minutes under package time instead of 2). Freeze before baking, tightly wrapped in plastic wrap and then foil, for up to 2 months. Thaw overnight in the refrigerator before baking.
Reheating from the fridge: Cover with foil and reheat at 350°F (175°C) for 15 to 20 minutes until hot throughout, then remove the foil for the last 5 minutes to crisp the topping. Individual portions reheat well in the microwave in 1.5 to 2 minutes.
[MAKE AHEAD TIP: Assemble the entire casserole through step 7 but don’t bake it. Cover and refrigerate for up to 24 hours. Add 5 to 8 extra minutes to the bake time when cooking straight from cold.]
Serving Suggestions
Tuna noodle casserole is a complete meal on its own, but a simple green salad with a sharp vinaigrette cuts right through the richness. Roasted broccoli or green beans on the side work just as well. For a bread component, crusty rolls for scooping up the creamy sauce are hard to beat. This is also a dish that travels well in the baking dish, which makes it a good contribution to potlucks or when dropping a meal off for someone.

Frequently Asked Questions
Can I make tuna noodle casserole ahead of time?
Yes, and it’s one of the better dishes for making a day in advance. Assemble everything including the breadcrumb topping, cover tightly, and refrigerate for up to 24 hours before baking. When you’re ready, add about 5 to 8 extra minutes to the baking time since the dish will be cold from the refrigerator. The topping may need an extra minute under the broiler at the end to crisp up properly.
Why does my casserole turn out watery?
The most common cause is under-drained tuna. Tuna packed in water releases a surprising amount of liquid when it heats up, and if you don’t press it dry, that liquid dilutes the cream sauce. The second most common cause is overcooking the pasta before it goes in the oven. Pulling the noodles 2 minutes early is important because they absorb moisture from the sauce as they finish cooking in the oven.
What can I substitute for egg noodles?
Wide egg noodles are the classic choice, but rotini, penne, or medium shells all work well because their ridges and curves hold onto the cream sauce. Avoid delicate pasta shapes like angel hair or thin spaghetti, which will break apart and turn mushy. For gluten-free, brown rice-based pasta holds its structure better than corn-based varieties in a baked casserole.
How do I know when it’s done baking?
Look for two things: a deep golden breadcrumb topping, and sauce that’s actively bubbling around the edges of the dish. The bubbling tells you the casserole is hot all the way through, not just browned on top. If the breadcrumbs are browning faster than the edges are bubbling, tent loosely with foil and give it another 5 minutes.
Can I use tuna in oil instead of tuna in water?
Yes. Oil-packed tuna has a slightly richer flavor and a less dry texture than water-packed. The key is draining it very thoroughly; press the lid down firmly and then blot with paper towels. If you leave oil behind, the finished sauce can feel greasy rather than creamy.
One Last Thing
Tuna noodle casserole has been on American dinner tables for good reason: it’s filling, affordable, genuinely delicious when made well, and comes together fast enough for a Tuesday. This from-scratch version takes maybe 10 extra minutes compared to using canned soup, and the creamier, more flavorful sauce is absolutely worth that. Make it once and you’ll see why this dish keeps getting handed down.
