Tuna Noodle Casserole

There are certain meals that feel like a warm hug, and for me, this Classic Creamy Tuna Noodle Casserole is at the top of that list. The aroma of the savory, cheesy sauce bubbling in the oven instantly fills my kitchen and brings back so many memories. It’s a departure from my usual veggie-heavy bakes, like my popular cauliflower and broccoli casserole, but it holds a special place in my heart as the ultimate comfort food.

Why This Dish is a Go-To in My Kitchen

What I adore most about this recipe is how it delivers incredible flavor without a huge time commitment. With just 20 minutes of prep and 25 minutes of cook time, I can have a deeply satisfying meal on the table in under an hour. It’s my secret weapon for busy weeknights when I’m craving something homemade and comforting. The ingredients are simple pantry staples, but they come together to create something truly special. The sauce, made with whole milk, chicken broth, and sharp cheddar, is luxuriously creamy without any canned soup. Paired with tender egg noodles, flaky albacore tuna, and sweet peas, every spoonful is a perfect balance of textures and flavors. It’s pure, uncomplicated comfort.

Ingredient Notes for Classic Creamy Tuna Noodle Casserole

I always choose solid white albacore tuna packed in water; it has a wonderfully firm, flaky texture. For the topping, Panko breadcrumbs are essential for that light, airy crunch, a technique I also love using on my beef macaroni casserole. Don’t skip the sharp cheddar—it’s key!

Ingredients

  

For the Casserole

• 12 oz Wide Egg Noodles
• 1/4 cup Unsalted Butter
• 1 medium Yellow Onion finely chopped
• 2 cloves Garlic minced
• 1/4 cup All-purpose flour
• 2 cups Whole milk
• 1 cup Chicken broth or vegetable broth
• 1 1/2 cups Shredded sharp cheddar cheese divided
• 1 tbsp Dijon mustard
• 1 tsp Kosher salt
• 1/2 tsp Black pepper freshly ground
• 2 cans (5 oz each) Solid white albacore tuna in water drained well and flaked
• 1 cup Frozen sweet peas

For the Crunchy Topping

• 1 cup Panko breadcrumbs
• 2 tbsp Unsalted butter melted
• 1/4 cup Grated Parmesan cheese

Equipment

• 9x13-inch baking dish
• Large Pot
• Large saucepan
• Whisk
• Colander

Method

 

Prep Oven and Cook Noodles

1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
2. Cook the egg noodles in a large pot of generously salted boiling water according to package directions, but cook for 2 minutes less than the recommended time to achieve al dente. Drain well and set aside.

Make the Creamy Sauce

1. While the noodles cook, melt 1/4 cup of butter in a large saucepan or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5-6 minutes. Stir in the minced garlic and cook for another minute until fragrant.
2. Sprinkle the flour over the onions and garlic. Cook, stirring constantly with a whisk, for 1 minute to cook out the raw flour taste.
3. Gradually whisk in the whole milk and chicken broth until smooth. Bring the mixture to a simmer, stirring frequently, and cook until the sauce has thickened enough to coat the back of a spoon, about 5-7 minutes.
4. Remove the saucepan from the heat. Stir in 1 cup of the shredded cheddar cheese, Dijon mustard, salt, and pepper. Continue stirring until the cheese is completely melted and the sauce is smooth.

Assemble and Bake

1. Gently fold the cooked egg noodles, drained tuna, and frozen peas into the cheese sauce until everything is evenly coated.
2. Pour the mixture into the prepared baking dish and spread into an even layer. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
3. In a small bowl, combine the Panko breadcrumbs, melted butter, and grated Parmesan cheese. Toss until the breadcrumbs are evenly moistened. Sprinkle the topping evenly over the casserole.
4. Bake uncovered for 20-25 minutes, or until the casserole is hot and bubbly and the topping is golden brown and crispy.
5. Let the casserole rest for 5-10 minutes before serving. This allows it to set up slightly. Garnish with fresh parsley if desired.

Notes

For best results, use solid white albacore tuna packed in water. You can substitute panko with crushed potato chips or crackers for a different crunchy topping. The casserole can be assembled up to a day ahead; cover and refrigerate. You may need to add 5-10 minutes to the baking time if baking from cold. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

How I Make Classic Creamy Tuna Noodle Casserole Step-by-Step

Bringing this dish together is such a rewarding process. I start by getting my oven preheating and cooking the wide egg noodles until they’re just shy of al dente. While they cook, I get to work on the heart of the casserole: the creamy sauce. In a large pot, I melt the butter and sauté the onion and garlic until fragrant, then whisk in the flour. I slowly stream in the milk and broth, letting it thicken into a beautiful, velvety sauce. This is where I melt in that sharp cheddar. From there, I just gently fold in the noodles, tuna, and peas. It’s a simple assembly process I find as comforting as preparing my holiday-favorite green bean casserole.

My Tips for the Perfect Outcome

• Always cook your egg noodles al dente. They’ll absorb some of the sauce and finish cooking in the oven without getting mushy.
• Shred your own cheese. Pre-shredded cheese has anti-caking agents that can make the sauce gritty.

How I Serve and Store This Dish

I almost always serve this dish steaming hot from the oven, usually with a crisp green salad or some roasted vegetables on the side. For leftovers, I allow the casserole to cool completely before covering it tightly and storing it in the fridge for up to three days. It reheats wonderfully, making it a reliable meal prep option much like my family’s favorite meatball casserole.

Frequently Asked Questions

Can I use a different type of pasta?

Absolutely! While I have a soft spot for classic wide egg noodles in this dish, you can easily substitute them with medium shells, rotini, or even penne. The key is to cook whichever pasta you choose to al dente so it holds its shape.

Can I make this casserole ahead of time?

Yes, this recipe is perfect for planning ahead. You can fully assemble the casserole a day in advance, but hold off on adding the panko topping. Just cover it tightly and refrigerate. When you’re ready to bake, add the topping and extend the baking time by about 10 minutes.

What can I use instead of peas?

If you’re not a fan of peas, feel free to get creative with other vegetables. I’ve had great success adding a cup of steamed broccoli florets, sautéed mushrooms, or even corn. It’s a wonderful way to customize the dish to your family’s tastes.

Can I freeze this tuna noodle casserole?

You certainly can. For the best texture upon reheating, I recommend freezing the casserole unbaked and without the panko topping. Assemble it in a freezer-safe dish, cover it well, and it will keep for up to three months. Thaw overnight before baking.

Conclusion

This classic tuna noodle casserole is a dish filled with warmth and nostalgia for me, and I truly hope it brings as much joy to your table as it does to mine. If you give it a try, I’d absolutely love to hear how it turned out!
