Ingredients Notes

The beauty of Cheesy Tuna Mornay lies in its simple ingredients, each working together to create the perfect harmony of flavors and textures. Here's what you’ll need:

• Canned Tuna: Opt for tuna in spring water or brine for the best flavor. Drain it well to avoid excess moisture in your sauce.
• Pasta: Short pasta like penne, elbow macaroni, or shells works best, as their shape holds onto the creamy sauce beautifully.
• Cheese: A mix of shredded cheddar and Parmesan creates the ultimate cheesy topping. For added depth, a sprinkle of mozzarella is a great addition.
• Milk: Whole milk is ideal for a rich, creamy white sauce. You can substitute with low-fat milk if you prefer, but the sauce will be slightly less indulgent.
• Butter and Flour: These create the roux, which is the base of the creamy white sauce. Don’t skip this step!
• Vegetables: Frozen peas and corn are classics, but you can also add diced carrots, broccoli, or even spinach for extra nutrients.

You'll also need a large pot for boiling pasta, a skillet for the sauce, and a casserole dish for baking.

How to Make This Cheesy Tuna Mornay

Creating this comforting Cheesy Tuna Mornay is easier than you think. Follow these steps, and you'll have a satisfying meal in no time.

Start by preheating your oven to 375°F (190°C). While the oven heats, bring a large pot of salted water to a boil. Cook your pasta according to package directions until al dente, then drain and set aside.

In a medium saucepan, melt butter over medium heat. Once melted, whisk in flour to form a smooth paste. Cook the roux for 1-2 minutes, stirring constantly, until it’s lightly golden. Gradually add milk, whisking continuously to avoid lumps. Cook until the sauce thickens and coats the back of a spoon.

Remove the sauce from the heat and stir in half the cheddar cheese, along with the Parmesan. Season with salt, pepper, and a pinch of nutmeg if desired.

In a large bowl, combine the cooked pasta, drained tuna, vegetables, and cheese sauce. Mix well, ensuring everything is evenly coated. Transfer the mixture to a greased casserole dish and sprinkle the remaining cheese on top.

Bake for 20-25 minutes, or until the top is golden and bubbling. For an extra-crispy topping, switch to the broiler for the last 2-3 minutes. Let the dish rest for a few minutes before serving.

Storage Options

This dish is perfect for make-ahead meals or storing leftovers. Here’s how to keep it fresh:

• Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Freeze: Portion the casserole into freezer-safe containers, ensuring it’s fully cooled before freezing. It will keep well for up to 3 months.
• Reheating: For best results, reheat in the oven at 350°F (175°C) until warmed through. If reheating from frozen, thaw in the refrigerator overnight first.

Variations and Substitutions

One of the best things about Cheesy Tuna Mornay is its versatility. Here are some ideas to make it your own:

• Add a crunchy topping: Sprinkle breadcrumbs mixed with melted butter and parsley over the top before baking for extra texture.
• Use different proteins: Swap the tuna for cooked chicken, canned salmon, or even leftover ham.
• Go gluten-free: Use gluten-free pasta and substitute gluten-free flour for the roux.
• Spice it up: Add a pinch of chili flakes or a dash of hot sauce for a bit of heat.
• Make it vegetarian: Skip the tuna and double up on the veggies for a hearty, meat-free version.

With so many ways to customize, this dish never gets old. Get creative and let your family’s tastes guide you.

Cheesy Tuna Mornay is the kind of recipe that feels like a warm hug on a plate. Whether you’re whipping it up for a quick family dinner or meal-prepping for the week, it’s a dish that delivers on flavor, comfort, and convenience every time. Enjoy!
