Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Cook the egg noodles according to package directions until they are al dente. Drain well and set aside.
- In a large saucepan or Dutch oven, heat the olive oil over medium heat. Add the diced onion and celery and cook until softened, about 5-7 minutes.
- Add 1/4 cup of unsalted butter to the saucepan and melt. Stir in the all-purpose flour and cook for 1 minute, stirring constantly, to create a roux.
- Gradually whisk in the whole milk and chicken or vegetable broth, ensuring there are no lumps. Bring the mixture to a simmer, whisking frequently, until the sauce thickens to your desired consistency (this usually takes about 5-7 minutes).
- Remove the saucepan from the heat. Stir in the Dijon mustard, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper. Add 1 cup of the sharp cheddar cheese and all of the Gruyere cheese (if using); stir until completely melted and the sauce is smooth.
- Add the drained, flaked tuna, thawed green peas, and cooked egg noodles to the cheesy sauce. Gently fold until everything is well combined and coated.
- Pour the entire mixture into the prepared 9×13 inch baking dish, spreading it evenly.
- In a small bowl, combine the Panko breadcrumbs, melted butter, grated Parmesan cheese, and paprika. Mix well.
- Evenly sprinkle the Panko topping over the casserole mixture in the baking dish.
- Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crispy.
- Let the casserole rest for 5-10 minutes before serving to allow the sauce to set slightly. Enjoy your ultimate tuna noodle casserole!
Notes
Pro Tips for Making This best tuna casserole
When I’m in the kitchen, I’ve gathered a few little secrets over the years that truly elevate dishes, and this best tuna casserole is no exception. These are the kinds of tips I’d share with a dear friend to ensure their dish turns out perfectly, every single time.
My Secret Trick: I always make sure to undercook the egg noodles slightly when boiling them for this best tuna casserole. They’ll continue to cook in the oven, ensuring they stay perfectly al dente and don’t turn mushy in the creamy sauce. It’s a small step that makes a huge difference!
Another tip I swear by is to use good quality tuna. Opt for albacore tuna packed in water for the cleanest flavor and best texture in your casserole. Draining it well is key to preventing a watery sauce.
Don’t skip toasting the Panko breadcrumbs with butter and Parmesan before sprinkling them on top. This pre-toasting step gives you that unbelievably crispy, golden crust without over-baking the casserole itself, ensuring a perfect texture contrast.
Finally, while the recipe calls for specific cheeses, feel free to use what you love! A blend of sharp cheddar and Gruyere offers wonderful depth, but Monterey Jack or even a little smoked gouda can add a delightful twist to this comforting dish.

Fun Variations for best tuna casserole
Part of the joy of home baking, and cooking in general, is making a recipe truly your own! This best tuna casserole is wonderfully adaptable. Here are some fun ways I’ve seen friends, and even myself, put a delightful spin on this classic:
Veggie Boost
My sister always adds a handful of finely diced bell peppers or some thawed corn along with the peas for an extra pop of color and sweetness. It’s a fantastic way to sneak in more veggies!
Spice It Up
For those who love a little warmth, a pinch of cayenne pepper or a dash of hot sauce in the creamy sauce can elevate the flavors beautifully. A friend of mine swears by a whisper of smoked paprika in the sauce to complement the cheesy goodness.
Cheese Swirls
While cheddar and Gruyere are lovely, try swapping one out for a different favorite! Pepper Jack could add a subtle kick, or a smoked cheddar could bring a deeper, more rustic flavor profile to your best tuna casserole.
What to Serve With best tuna casserole
This creamy, comforting best tuna casserole is truly a meal in itself, but a few simple accompaniments can make it feel even more special and balanced. Think about fresh, vibrant flavors that cut through the richness!
I love serving it alongside a crisp, green salad with a light vinaigrette. The freshness of the greens provides a wonderful contrast to the warm, creamy casserole. It’s simple, elegant, and always a crowd-pleaser.
Another lovely pairing is some steamed green beans or roasted asparagus. A little lemon zest over the vegetables adds a bright touch that complements the savory casserole beautifully. For a quicker option, my mom always made a simple side of buttered peas when we had casserole, and the nostalgia is just perfect!
And if you want to be truly indulgent, a warm, crusty bread to sop up any leftover creamy sauce is just divine. It’s all about creating that cozy, comforting meal experience.
How to Store best tuna casserole
Making a big batch of the best tuna casserole means you get to enjoy leftovers, which are often even better the next day! Proper storage ensures that every bite is as delicious as the first.
Refrigeration Tips
Once your casserole has cooled completely, cover it tightly with plastic wrap or transfer individual portions to airtight containers. It will keep beautifully in the refrigerator for up to 3-4 days. When reheating, I like to warm it gently in the microwave or a low oven until heated through, sometimes adding a splash of milk if it seems a little dry, to bring back that lovely creaminess.
Freezing Instructions
If you’ve made a large quantity or want to prep ahead, this best tuna casserole freezes wonderfully! Once cooled, wrap the entire casserole dish (if freezer-safe) tightly with several layers of plastic wrap and then foil, or portion it into freezer-safe containers. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating. A light dusting of paprika after reheating can bring back a lovely fresh look!
Nutritional Benefits
While this creamy, hearty dish is undeniably a comfort food, our best tuna casserole also offers some lovely nutritional benefits. It’s packed with protein from the albacore tuna, which is essential for muscle health, and the whole milk provides a good source of calcium. The added vegetables like peas and celery contribute fiber and vitamins, making it a satisfying and wholesome meal that truly nourishes the body and soul.
FAQs
Faq 1
Can I make this best tuna casserole ahead of time?
Yes, absolutely! You can assemble the casserole (without the crispy topping) up to a day in advance. Store it covered in the refrigerator, then add the topping and bake as directed when you’re ready to enjoy this comforting dish.
Faq 2
What kind of noodles are best for tuna casserole?
Medium egg noodles are traditionally used and provide the perfect tender texture for this best tuna casserole. However, elbow macaroni or even rotini can also work wonderfully if you’re looking for an alternative.
Faq 3
Can I use canned cream of mushroom soup instead of making a roux?
While you can use canned soup for convenience, making a homemade roux creates a much richer, creamier, and fresher-tasting sauce for this best tuna casserole. It’s a step that truly elevates the dish.
Faq 4
Why is my tuna casserole dry?
A dry best tuna casserole usually means it was overbaked or didn’t have enough sauce. Ensure your noodles are slightly undercooked, and don’t bake it longer than needed. If reheating, a splash of milk can help restore moisture.
