Ingredients Notes

The beauty of this Cheesy Tuna Mornay lies in its simple, everyday ingredients that combine to make something truly special. Each one is essential for building the layers of flavor that make this dish unforgettable.

• Canned Tuna: Use good-quality tuna in spring water or oil for the best flavor. I prefer chunk-style tuna, as it holds up better in the sauce compared to flaked varieties. Drain it well before adding it to the dish.
• Pasta: Elbow macaroni or small shells work beautifully, but feel free to experiment with any short pasta shape you have on hand. Make sure to cook the pasta just until al dente, as it will continue to soften in the oven.
• Cheese: Sharp cheddar cheese is my go-to for a rich and tangy flavor. For an extra creamy sauce, add a handful of grated Parmesan or mozzarella. Pro tip: Always shred your cheese from a block for the smoothest sauce.
• Milk and Cream: A combination of whole milk and heavy cream creates a luscious sauce that coats the pasta perfectly. If you’re watching your fat intake, you can use low-fat milk, but the sauce won’t be as rich.
• Vegetables: Frozen peas or sweet corn kernels are classic additions, adding color and a touch of sweetness. Feel free to experiment with other veggies like diced carrots or chopped spinach for extra nutrition.
• Breadcrumbs: Topping the casserole with buttery breadcrumbs adds a delicious crunch that contrasts with the creamy filling. You can use panko or traditional breadcrumbs, whichever you have on hand.

Finally, you’ll need a large saucepan for the sauce and a 9x13-inch baking dish to bake everything to bubbly, golden perfection.

How To Make This Cheesy Tuna Mornay

Creating this creamy, cheesy comfort dish is easier than you might think. Follow these simple steps, and you’ll have dinner ready in no time!

1. Cook the pasta: Start by bringing a large pot of salted water to a boil. Add your pasta and cook until al dente, about 1-2 minutes less than the package instructions. Drain and set aside. The pasta will finish cooking in the oven, so don’t overcook it!
2. Make the cheesy sauce: In a large saucepan over medium heat, melt some butter until it starts to foam. Whisk in the flour and cook for about 1-2 minutes, forming a light roux. Slowly add the milk and cream, whisking continuously to prevent lumps. Keep stirring until the sauce thickens, about 5-7 minutes.
3. Add cheese and seasonings: Once the sauce has thickened, remove it from heat and stir in the shredded cheddar cheese. Mix until the cheese melts smoothly into the sauce. Season generously with salt, pepper, and a pinch of nutmeg for extra depth of flavor.
4. Assemble the dish: Gently fold in the cooked pasta, drained tuna, and any vegetables you’re using, like peas or corn. Make sure everything is well coated in the cheesy sauce. Pour the mixture into your prepared baking dish and smooth out the top.
5. Top with breadcrumbs: In a small bowl, mix the breadcrumbs with melted butter. Sprinkle this mixture evenly over the casserole for a golden, crispy finish. You can also add a little extra cheese on top if you’re feeling indulgent!
6. Bake to perfection: Preheat your oven to 375°F (190°C). Bake the Tuna Mornay for 20-25 minutes, or until the top is bubbly and golden brown. Let it rest for 5 minutes before serving – trust me, it’s worth the wait.

In about 45 minutes, you’ll have a Cheesy Tuna Mornay that’s perfectly creamy and comforting. Serve it with a simple green salad or crusty bread for a complete meal.

Storage Options

Have leftovers? This dish is just as tasty the next day, and it stores beautifully. Here’s how to make the most of your Cheesy Tuna Mornay:

• Refrigerate: Store any leftovers in an airtight container in the fridge for up to 3 days. The flavors will deepen as it sits, making for an even more delicious meal later.
• Freeze: You can freeze Tuna Mornay for up to 3 months. To freeze, let the dish cool completely, then transfer it to a freezer-safe container. For best results, thaw in the refrigerator overnight before reheating.
• Reheat: Warm leftovers in a 350°F (175°C) oven for 15-20 minutes, or until heated through. If the sauce seems too thick, stir in a splash of milk before reheating to bring back the creaminess.

Variations and Substitutions

The best part about Cheesy Tuna Mornay is how adaptable it is. Here are some ideas to change it up:

• Switch up the protein: If tuna isn’t your favorite, try using cooked shredded chicken, salmon, or even leftover rotisserie chicken. It’s a great way to use up what you have.
• Add extra vegetables: Boost the nutrition by adding more veggies like diced bell peppers, chopped broccoli, or sautéed mushrooms. Just be sure to sauté or steam them before mixing into the sauce.
• Go gluten-free: Swap out regular pasta for your favorite gluten-free variety. Use gluten-free breadcrumbs or crushed rice crackers for the topping.
• Make it spicy: For a little heat, add chopped jalapeños or a pinch of chili flakes to the sauce. You can also stir in hot sauce to taste.
• Herby twist: Fresh herbs like chopped parsley or dill brighten up the dish and add a burst of freshness. You can also sprinkle dried Italian herbs into the sauce for more flavor.

No matter how you choose to customize it, this Cheesy Tuna Mornay is a forgiving and flavorful recipe. Don’t be afraid to make it your own – it’s all about using what you love and what you have on hand!
