Ingredients You’ll Need

This recipe relies on a beautiful balance of simple ingredients that come together to create a dish that feels indulgent yet approachable.

• Egg noodles: Soft and tender, they provide the perfect base that holds all the delicious flavors.
• Condensed cream of mushroom soup: Adds a creamy, savory richness that binds everything together.

Ingredient Substitutions & Tips

• Egg noodles: You can substitute with other pasta shapes like penne or rotini if preferred.
• Condensed cream of mushroom soup: If you want a lighter version, try cream of celery or cream of chicken soup instead.

How to Make Best Tuna Casserole Recipe

Step 1: Cook the Egg Noodles

Fill a large pot with lightly salted water and bring it to a rolling boil. Add the egg noodles and cook them for 7 to 9 minutes until tender yet firm to the bite—al dente is the key here. Once done, drain the noodles thoroughly and set aside to cool slightly. They should be perfectly cooked to absorb the creamy mixture later without falling apart.

💡 Pro Tip: Stir occasionally while boiling to prevent the noodles from sticking together.

Step 2: Preheat the Oven

Set your oven to 425 degrees F (220 degrees C) so it’s nice and hot when you’re ready to bake. This temperature helps create that irresistible crispy top while melting the cheese to gooey perfection.

Step 3: Mix the Casserole Filling

In a large bowl, combine the cooked noodles, condensed cream of mushroom soup, 1 cup of shredded cheddar cheese, drained tuna, frozen peas, sliced mushrooms, and chopped onion. Gently toss everything together until the ingredients are evenly coated with the creamy soup and cheese, creating a luscious filling bursting with flavor.

💡 Pro Tip: Use a rubber spatula to fold the ingredients carefully, keeping the tuna flakes intact.

Step 4: Assemble the Casserole

Transfer the mixture into a greased 9×13-inch baking dish, spreading it out evenly. Then, sprinkle the crushed potato chips evenly over the top, followed by the remaining 1 cup of cheddar cheese. This layering will deliver a perfect golden crust with a satisfying crunch to every bite.

💡 Pro Tip: For extra flavor, toss the crushed potato chips with a little melted butter before sprinkling on top.

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 15 to 20 minutes, until the cheese is melted, bubbling, and the edges are lightly golden. This final step melds all the flavors and textures into one unforgettable dish.

💡 Pro Tip: Keep an eye on the topping to prevent burning and ensure it’s perfectly crisp.

Step 6: Serve and Enjoy

Let the casserole rest for a few minutes after baking, then scoop out generous portions while it’s still warm. The creamy, cheesy interior combined with the crunchy topping makes every mouthful a comforting celebration.

Common Mistakes to Avoid

Learn from these common pitfalls:

• Overcooked noodles: They can become mushy and lose their texture, making the casserole soggy.
• Not draining tuna properly: Excess moisture can water down the flavors and make the casserole runny.
• Skipping the crispy topping: Without the crushed chips, the casserole might lack that delightful crunch.
• Using low-quality cheese: Mild or processed cheese won’t provide the rich flavor this dish deserves.
• Underbaking: The casserole needs enough time to melt the cheese thoroughly and brown the topping.
• Not letting it rest: Serving immediately can cause the casserole to fall apart.

Delicious Variations to Try

Once you’ve mastered the classic version, try these twists to keep things exciting:

Cheesy Broccoli Tuna Casserole

Add steamed broccoli florets to the mix for a vibrant, healthy crunch and a burst of color.

Spicy Tuna Casserole

Stir in a teaspoon of smoked paprika or a dash of cayenne pepper for a gentle kick that wakes up the flavors.

Herbed Tuna Casserole

Fresh chopped parsley or dill adds a bright, herbal note that complements the creamy sauce beautifully.

Gluten-Free Version

Make Ahead and Storage

Storing Leftovers

Allow leftovers to cool completely before transferring to an airtight container. Store in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it a great make-ahead meal.

Freezing

This casserole freezes beautifully! Assemble it in a freezer-safe dish, cover tightly with foil, and freeze for up to 2 months. Thaw overnight in the fridge before baking as directed, adding extra baking time if needed.

Reheating

Reheat individual portions in the microwave until warmed through, or heat the entire casserole in a 350°F oven for 15-20 minutes until bubbly and heated evenly.

FAQs

Can I use fresh mushrooms instead of canned?

Try using dairy-free cheese and a dairy-free cream of mushroom soup to adapt this recipe. The texture and flavor will differ slightly but still be delicious.

How do I prevent the chips from getting soggy?
