Classic Creamy Tuna Noodle Casserole
Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Cook the egg noodles in a large pot of salted boiling water according to package directions, until al dente. Drain well and set aside.
- In a large skillet or Dutch oven, melt 1/4 cup unsalted butter over medium heat. Add the diced onion and sliced mushrooms and sauté for 5-7 minutes, until softened. Add the minced garlic and cook for another minute until fragrant. Remove the vegetables from the skillet and set aside.
- In the same skillet, melt the remaining 1/4 cup butter (if needed, otherwise just use the residual butter in the pan). Sprinkle in the all-purpose flour and whisk constantly for 1-2 minutes to create a roux, cooking out the raw flour taste.
- Gradually whisk in the warmed milk and broth, a little at a time, ensuring no lumps form. Continue to whisk and cook until the sauce thickens to your desired consistency, about 5-7 minutes.
- Remove the skillet from the heat. Stir in the shredded cheddar cheese until melted and smooth. Season with 1/2 tsp salt, 1/4 tsp black pepper, dried thyme, and Dijon mustard (if using). Taste and adjust seasonings as needed.
- Gently fold the sautéed onion and mushrooms, drained flaked tuna, and frozen peas into the creamy sauce. Add the cooked and drained egg noodles and stir until everything is well combined and coated.
- Pour the noodle mixture into the prepared 9×13 inch baking dish, spreading it evenly.
- In a small bowl, combine the Panko breadcrumbs, 2 tablespoons of melted butter, and grated Parmesan cheese (if using). Sprinkle this topping evenly over the casserole.
- Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crispy.
- Remove from oven and let rest for 5-10 minutes before serving. Garnish with fresh chopped parsley, if desired.
Notes
Make Ahead: You can assemble the casserole (without the topping) and refrigerate for up to 24 hours. Add the topping just before baking and add an extra 10-15 minutes to the baking time.
Pro Tips for Making This Tuna Noodle Casserole
Ensuring your Tuna Noodle Casserole turns out perfectly every time is all about those little touches, much like how my grandmother always knew just when her pies were done with a gentle nudge of the crust.
First, always cook your egg noodles al dente. They’ll continue to cook in the oven, and nobody wants mushy noodles in their casserole! A slightly firm noodle holds up beautifully to the creamy sauce.
My Secret Trick: For an extra layer of flavor and richness in your creamy sauce, I always sauté the onions and mushrooms until they’re deeply golden and caramelized before adding the flour. This really brings out their sweetness and adds an incredible depth that elevates the entire casserole.
When choosing your tuna, I find that tuna packed in olive oil adds a lovely richness and depth of flavor that tuna in water just can’t quite match. However, either works wonderfully depending on your preference!
Finally, don’t skimp on the crispy topping! The combination of Panko breadcrumbs and Parmesan cheese creates that irresistible crunch that contrasts beautifully with the creamy interior of this Tuna Noodle Casserole. A little extra butter melted into the breadcrumbs ensures it turns golden brown and utterly delicious.
Fun Variations for Tuna Noodle Casserole
One of the joys of home baking and cooking is the freedom to get creative and adapt recipes to your family’s tastes! This Classic Tuna Noodle Casserole is a fantastic canvas for your culinary imagination.
Veggie Boosts
If you want to sneak in a few more veggies, feel free to add finely diced carrots or celery to the onion and mushroom sauté. My friend Sarah always loves when I throw in some frozen corn along with the peas for an extra pop of color and sweetness.
Cheesy Twists
While sharp cheddar is a classic, don’t hesitate to experiment with other cheeses! A blend of Gruyere and white cheddar would be absolutely divine, adding a nuttier, more sophisticated note. Or, for a little kick, a touch of Monterey Jack with jalapeños could be a fun surprise!
Topping Alternatives
If you’re not a fan of Panko, crushed crackers (like Ritz) or even crushed potato chips make for a wonderfully savory and crunchy topping. My sister once topped her Tuna Noodle Casserole with crushed garlic and herb croutons, and it was surprisingly delicious!
What to Serve With Tuna Noodle Casserole
While this hearty and comforting Tuna Noodle Casserole is truly a meal in itself, pairing it with a simple side can elevate the entire experience, much like a perfectly brewed cup of tea with a slice of my lemon loaf.
I love serving this creamy casserole alongside a crisp, green salad with a light vinaigrette. The fresh, tangy greens cut through the richness of the casserole beautifully, offering a refreshing contrast.
Another wonderful option is a side of steamed green beans or roasted asparagus. They add a lovely vibrant color and a gentle, earthy flavor that complements the savory notes of the tuna and cheese.
For a comforting, carb-on-carb pairing (and sometimes, that’s just what you need!), a simple slice of crusty bread or warm dinner rolls is perfect for soaking up any extra creamy sauce. My mom always had a basket of warm rolls ready whenever she made a casserole, and it just feels right.
How to Store Tuna Noodle Casserole
Part of the magic of a good casserole is how well it keeps, offering delicious leftovers that taste just as good, if not better, the next day! Proper storage ensures your Tuna Noodle Casserole remains a comforting treat.
Refrigerator Storage
Once cooled completely, transfer any leftover Tuna Noodle Casserole to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. This makes it a fantastic make-ahead meal or a perfect option for meal prepping throughout the week.
Freezing for Later
Yes, you can freeze Tuna Noodle Casserole! Allow the casserole to cool completely, then transfer it to a freezer-safe, airtight container or wrap individual portions tightly in foil and then plastic wrap. It will stay fresh in the freezer for up to 2-3 months.
Reheating Tips
To reheat, thaw frozen portions in the refrigerator overnight. For both refrigerated and thawed portions, you can warm them gently in the microwave or in an oven set to 300-325°F (150-160°C) until heated through. My personal tip? If the topping has lost some of its crispness, a quick 5-10 minutes under the broiler at the very end can bring it right back to life! Just watch it closely to prevent burning.
Nutritional Benefits
This Classic Tuna Noodle Casserole isn’t just about comfort; it also offers some wholesome goodness. With protein-rich tuna and milk providing essential nutrients, it’s a satisfying meal. The vegetables like onions, mushrooms, and peas add fiber and vitamins, showing that a comforting treat can indeed be both delightful and nourishing.
FAQs
Faq 1
Can I make this casserole ahead of time?
Absolutely! You can assemble the entire Tuna Noodle Casserole (without the breadcrumb topping) up to 24 hours in advance. Cover it tightly and refrigerate. Add the topping just before baking for the best crispy results.
Faq 2
What kind of tuna should I use?
I recommend using albacore tuna, either packed in water or olive oil. Tuna packed in oil often provides a richer flavor and texture, but both work well for this Classic Tuna Noodle Casserole. Ensure it’s well-drained.
Faq 3
Can I use a different kind of pasta?
While medium egg noodles are traditional for this Tuna Noodle Casserole and absorb the creamy sauce beautifully, you can certainly experiment! Penne, rotini, or even macaroni would be good substitutes.
Faq 4
How do I prevent the casserole from being dry?
The key is to ensure your sauce is creamy and plentiful. Don’t overcook your noodles initially, as they’ll absorb more liquid in the oven. If reheating, a splash of milk or broth can help moisten this Tuna Noodle Casserole.
