Ingredients

To make this classic tuna casserole, you will need a few simple ingredients. This recipe focuses on fresh flavors and pantry staples for a delicious result.

For the Casserole:

  • 3 cups egg noodles, measured dry (approximately 6 ounces)
  • 1 tablespoon butter
  • 1 small onion, diced
  • 2 ribs celery, diced
  • ⅔ cup frozen peas, thawed
  • 1 (5-ounce) can tuna, drained
  • 1 (10.5-ounce) can condensed cream of mushroom soup
  • ⅓ cup milk
  • 1 cup shredded cheddar cheese
  • 1 tablespoon chopped fresh parsley or 1 teaspoon dried parsley

For the Crumb Topping:

  • ½ cup panko breadcrumbs
  • 1 tablespoon melted butter
  • ½ cup shredded cheddar cheese
  • 1 tablespoon chopped fresh parsley or 1 teaspoon dried parsley

Notes & Substitutions

  • Tuna: Water-packed tuna is lighter and preferred for this dish, but oil-packed also works. Just drain it really well. According to Health.com, consuming tuna provides essential nutrients like B6, B12, selenium, and omega-3 fats.
  • Soup: Cream of mushroom soup is traditional, but feel free to swap it with cream of celery or cream of chicken for a different flavor profile in your creamy tuna pasta dish.
  • Noodles: Egg noodles are classic, but you can use other small pasta shapes like elbow macaroni, penne, or rotini.
  • Vegetables: Besides peas, consider adding thawed corn, chopped steamed broccoli florets, or diced bell peppers for extra color and nutrients.
  • Cheese: Sharp cheddar offers great flavor. Gruyère, mozzarella, or a Monterey Jack blend also melt beautifully.
  • Topping: Panko breadcrumbs give the best crunch. You can also use crushed butter crackers (like Ritz) or crispy fried onions for a different texture.

Instructions For The Best Tuna Casserole

Follow these simple steps to prepare your delicious tuna casserole. This guide helps ensure a perfect, creamy, and bubbly result every time.

  1. Preheat Oven & Prepare Topping: Preheat your oven to 425°F (220°C). In a small bowl, combine the panko breadcrumbs, melted butter, shredded cheddar cheese, and parsley for the topping. Set this mixture aside.
  2. Cook Noodles: Bring a large pot of salted water to a boil. Add the egg noodles and cook them according to package directions until they are al dente. This means they should be firm to the bite. Drain the noodles thoroughly and rinse them under cold water to stop the cooking process and prevent sticking.
  3. Sauté Aromatics: While the noodles cook, melt 1 tablespoon of butter in a large skillet over medium heat. Add the diced onion and celery to the skillet. Cook, stirring occasionally, for 5-7 minutes, or until the vegetables have softened and become tender.
  4. Combine Casserole Ingredients: In a large mixing bowl, combine the cooked and drained noodles, the sautéed onion and celery mixture, thawed frozen peas, drained tuna, condensed cream of mushroom soup, milk, 1 cup of shredded cheddar cheese, and 1 tablespoon of fresh or dried parsley. Mix all the ingredients well until everything is evenly combined and coated.
  5. Assemble Casserole: Transfer the entire noodle mixture from the mixing bowl into your prepared 2-quart casserole dish. Spread the mixture out evenly across the bottom of the dish.
  6. Add Topping: Sprinkle the reserved breadcrumb topping mixture evenly over the top of the noodle mixture in the casserole dish. This creates a wonderful golden, crispy crust for your homemade tuna casserole.
  7. Bake: Place the casserole dish in the preheated oven. Bake for 18-20 minutes, or until the casserole is hot and bubbly around the edges and the topping is golden brown and crispy. Remove from the oven and let it rest for a few minutes before serving.

Pro Tips & Troubleshooting

Making the perfect tuna casserole is simple with a few smart techniques. These tips help you avoid common pitfalls and enhance your dish.

  • Prevent Mushy Noodles: Cook your noodles only until al dente. They will finish cooking in the oven, ensuring a pleasant texture.
  • Ensure Crispy Topping: For an extra-crispy topping, you can broil the casserole for the last 1-2 minutes of baking. Watch it closely to prevent burning.
  • Achieve Maximum Creaminess: Using whole milk or even a splash of half-and-half instead of skim milk will make the sauce richer and creamier.
  • Seasoning Tips: Taste your mixture before baking and adjust seasoning. A pinch of black pepper, garlic powder, or a dash of hot sauce can elevate the flavor of your delicious tuna bake.
  • Adjust Consistency: If your sauce seems too thick, add an extra splash of milk. If it looks a little thin, don’t worry, the cheese and noodles will absorb some moisture during baking.

Serving, Storage & Variations

Enjoying your homemade tuna casserole is easy, and so is handling leftovers. This dish is versatile, allowing for many creative twists.

Serve this comforting tuna casserole with a simple green side salad for freshness, or enjoy it with warm, crusty biscuits or a slice of garlic bread.

For storage, allow any leftovers to cool completely before transferring them to an airtight container. Refrigerate promptly and consume within 3-4 days. To reheat, warm individual portions in the microwave or cover and bake in the oven until heated through.

Yes, this classic tuna noodle casserole freezes beautifully! You can freeze it either cooked or uncooked. Wrap the casserole dish tightly with plastic wrap and then foil. For best results, thaw thoroughly in the refrigerator overnight before baking or reheating. Cooked casserole can be frozen for up to 3 months.

Variations

  • Add Different Vegetables: Enhance your tuna noodle casserole by adding steamed mushrooms, diced bell peppers, or even a can of drained water chestnuts for extra crunch.
  • Experiment with Various Cheeses: Swap cheddar for Gruyère, smoked gouda, or a Monterey Jack blend to change the flavor profile.
  • Spice It Up: Add a dash of hot sauce to the mixture, or sprinkle a pinch of paprika or cayenne pepper over the topping for a little kick.
  • Include Protein Boosters: For an even heartier meal, stir in some chopped hard-boiled eggs or cooked shredded chicken alongside the tuna.
