The Essential Ingredients for This Classic Casserole

This iconic dish uses a handful of high-quality pantry staples to create its signature comforting and savory flavor.

• The From-Scratch Cream Sauce (The Secret to Success!):
  • The Roux & Béchamel: A classic mixture of salted butter and all-purpose flour is the foolproof thickener that transforms a thin liquid into a rich and creamy béchamel sauce. This is the non-negotiable foundation for a luxurious, from-scratch casserole that is a world away from canned soup.
  • The Sherry: This is the secret, sophisticated ingredient that elevates the sauce from simple to spectacular. A splash of dry sherry adds a wonderful, complex, nutty, and aromatic depth of flavor that perfectly complements the mushrooms and tuna.
• The Tuna: For the best, most delicious result with large, meaty flakes (not a mushy texture), it is highly recommended to use a high-quality, solid white albacore tuna that is packed in water, as the recipe suggests.
• The Crispy Panko Topping: A simple combination of panko breadcrumbs, melted butter, and fresh parsley creates the perfect, golden-brown, crunchy crust. Panko are Japanese-style breadcrumbs that are lighter and flakier than regular breadcrumbs, which is the secret to a super crispy, not greasy, topping.
• The Pasta: A classic, comforting wide egg noodle is the perfect choice for this dish. Its tender, toothsome texture is the perfect partner for the creamy sauce.

Step-by-Step to the Best Tuna Noodle Casserole

This delicious, one-dish meal is incredibly simple to prepare.

Step 1: Cook the Pasta and Make the Crispy Topping

Step 1: First, preheat your oven to 400°F (200°C). Generously butter a 9×13-inch baking dish.

Step 2: Bring a large pot of heavily salted water to a boil. Cook your 12 ounces of wide egg noodles according to the package directions until they are perfectly al dente.

Pro Tip: It is a great idea to cook your noodles for 1 minute less than the package directs. The pasta will continue to cook in the hot sauce in the oven, and this will prevent your final casserole from being soft and mushy. Drain the pasta and set it aside.

Step 3: While the pasta is cooking, prepare your topping. In a small bowl, melt the remaining 4 tablespoons of butter in the microwave. Stir the 1/2 cup of panko breadcrumbs and the remaining 1 tablespoon of parsley into the melted butter and toss to combine.

Part 2: Create the From-Scratch Cream Sauce

Step 1: In a large skillet, melt 4 tablespoons of the butter over medium heat. Add the 1 diced medium onion and cook for 3 to 4 minutes, until it is starting to soften. Add the 6 ounces of finely chopped white button mushrooms and continue to cook, stirring, for a couple of more minutes.

Step 2 (Make the Roux): Sprinkle the 1/4 cup of all-purpose flour evenly over the vegetables. Stir so that the flour coats the onions and mushrooms thoroughly and cook, stirring, for one more minute to cook out the raw flour taste.

Step 3: Slowly and gradually, while whisking constantly, pour in the 3 cups of warmed whole milk and the 1/2 cup of dry sherry until the mixture is completely smooth and free of lumps.

Step 4: Continue to cook the sauce, whisking constantly, for 3 to 4 minutes, until it is nice and thick. Sprinkle in salt and pepper to your taste.

Part 3: Assemble and Bake Your Casserole

Step 1: Add your 3 cans of drained tuna to the sauce and stir it in. Then, stir in the 1/4 cup of finely chopped red bell pepper and 1 tablespoon of the fresh parsley.Step 2: Stir in your cooked and drained egg noodles until they are completely and beautifully coated in the creamy sauce.Step 3: Transfer the entire noodle mixture to your prepared 9×13-inch baking dish.Step 4: Top the casserole with your prepared, buttery breadcrumb mixture.Step 5: Bake for 25 to 30 minutes, until the topping is a beautiful, deep golden brown and crispy and the sauce is hot and bubbly around the edges.

Let the casserole rest for a few minutes before serving.

Tuna Noodle Casserole is the ultimate make-ahead and freezer-friendly meal.

• Make-Ahead: You can fully assemble the entire, unbaked casserole (it’s best to wait to add the breadcrumb topping until just before baking) up to 2 days in advance. Simply cover it tightly with foil and store it in the refrigerator. When you are ready to bake, you may need to add 15-20 minutes to the baking time.
• Storage: Store any leftovers, well-covered, in the refrigerator for up to 5 days.
• Freezing: This casserole freezes beautifully! You can freeze it either before or after baking. Let it cool completely, then wrap the pan very well in a double layer of plastic wrap and then a layer of foil. It will keep in the freezer for up to 3 months. Thaw it overnight in the refrigerator before baking or reheating.

Frequently Asked Questions (FAQs)

Q1: What is the absolute secret to a creamy, from-scratch casserole sauce that isn’t lumpy? The secret is to make a proper roux and to add your liquid slowly. By first cooking the flour in the melted butter, you are coating each particle of flour in fat. Then, when you add your milk and broth slowly and gradually, while whisking constantly, you are ensuring that the flour will dissolve smoothly into the liquid and create a beautiful, lump-free, and velvety sauce.

Q2: Can I make this tuna noodle casserole ahead of time? Yes, this is a perfect make-ahead meal! You can fully assemble the entire unbaked casserole, cover it tightly, and keep it in the refrigerator for up to 2 days. When you are ready to bake, you can sprinkle on the fresh breadcrumb topping and pop it in the oven (you may need to add 15-20 minutes to the baking time, as it will be starting from cold).

Q3: What are the best kind of noodles to use for a casserole? A classic, sturdy wide egg noodle is the traditional and perfect choice. Their rich, tender texture is a fantastic partner for the creamy sauce. However, you could also use another medium pasta shape, like penne, rotini, or medium shells.

Q4: Can I freeze this tuna noodle casserole? Yes, this is a fantastic freezer meal! You can freeze it either baked or unbaked. Let the casserole cool completely, then wrap the dish very well in a double layer of plastic wrap and then a layer of foil. It will keep in the freezer for up to 3 months. Let it thaw overnight in the refrigerator and then bake (or reheat) it.

Q5: Can I make this recipe without the sherry? Of course! If you prefer to cook without alcohol, you can simply substitute the 1/2 cup of dry sherry with an equal amount of extra chicken broth.
