Italian Tuna Pasta Bake: A Cheesy, Comforting Classic Reimagined

I have such fond memories of helping my grandmother make tuna casserole. While some may scoff at the dish, for me, it represents warmth, family, and a certain comforting simplicity. I can still picture her, humming softly, as she layered the creamy tuna mixture with crispy potato chips on top. This Italian Tuna Pasta Bake is my modern take on that childhood favorite, swapping the chips for a golden, cheesy crust and adding a vibrant mix of tomatoes, spinach, and herbs for a truly irresistible experience. It’s comfort food elevated, and I hope it brings you the same joy it brings me.

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 6
• Dietary Type: Dairy

Ingredients

• 2 cups fusilli (or any other kind of pasta)
• ½ onion, peeled and finely chopped
• 2 tablespoons butter
• 1 tablespoon cornflour
• ½ cup water
• 1 (14 ounce) can low-sodium tomato soup, condensed
• 1 pinch mixed herbs
• 1-2 tablespoons chopped fresh parsley
• 1 (7 ounce) can tuna, drained and flaked
• Fresh ground black pepper

White Sauce with Spinach:

• ½ onion, peeled and finely chopped
• 2 tablespoons butter
• 2 tablespoons plain flour
• 1 ¼ cups milk
• 2 cups baby spinach, chopped
• 1 cup cheddar cheese, grated, plus a little extra for the topping

Equipment Needed

• Large pot
• Saucepan
• Baking dish

Instructions

1. Preheat your oven to 350°F (175°C). It’s important to let the oven heat up completely to ensure even cooking and a beautifully golden crust.
2. Cook the pasta in salted water until al dente. This means it should be firm to the bite, not mushy. Overcooked pasta will become even softer during baking, resulting in a less appealing texture. Once cooked, drain and refresh in cold water to stop it from overcooking.
3. While the pasta is cooking, prepare the tomato sauce. Melt 2 tablespoons of butter in a saucepan over medium heat. Sauté the finely chopped onion until soft and translucent. This usually takes about 5-7 minutes.
4. In a separate small bowl, stir the cornflour into the water until completely dissolved. This prevents lumps from forming in the sauce.
5. Add the cornflour mixture to the onion pan, along with the can of tomato soup. Bring the mixture to a boil, stirring constantly to prevent sticking.
6. Once boiling, add a pinch of mixed herbs and then cook gently, stirring continuously, for 5 minutes. This allows the flavors to meld together and the sauce to thicken slightly.
7. Mix in the drained and flaked tuna. Heat through gently. Season to taste with fresh ground black pepper. Be mindful of the salt content of the tuna and tomato soup when seasoning.
8. Mix the tuna and tomato mixture into the cooked pasta, ensuring it is evenly coated.
9. Now, let’s move onto the cheese and spinach sauce. Melt 2 tablespoons of butter in a separate saucepan. Sauté the finely chopped onion until transparent, about 5 minutes.
10. Add the flour and continue stirring the mixture constantly to create a roux. Cook for about 1-2 minutes, stirring constantly, to cook out the raw flour taste.
11. Gradually pour in the milk, a little at a time, while continuing to stir vigorously. This prevents lumps from forming and ensures a smooth sauce.
12. Keep stirring until the sauce has thickened and is smooth. This may take several minutes.
13. Add the chopped spinach and stir until it has wilted. This usually takes only a minute or two.
14. Remove the saucepan from the heat and stir in 1 cup of grated Cheddar cheese until melted and fully incorporated.
15. Grease a baking dish to prevent sticking.
16. Add the tuna and tomato mixture with the pasta to the greased baking dish.
17. Pour the spinach sauce evenly over the top of the pasta mixture.
18. Sprinkle with a little extra grated Cheddar cheese for a golden, bubbly crust.
19. Bake in the preheated oven for 25 minutes, or until golden brown and bubbly.
20. Allow the bake to cool slightly before serving. This will prevent it from being too runny.

Expert Tips & Tricks

• For an extra layer of flavor, try adding a clove of minced garlic to the onions when sautéing.
• If you prefer a creamier sauce, you can substitute half-and-half or heavy cream for some of the milk.
• To prevent the top from browning too quickly, cover the baking dish with foil during the last 10 minutes of baking.
• For a crispy topping, try adding a sprinkle of breadcrumbs or crushed crackers along with the cheese.
• Don’t overcook the pasta! Aim for al dente, as it will continue to cook in the oven.

Serving & Storage Suggestions

Serve the Italian Tuna Pasta Bake warm, straight from the oven. It pairs well with a simple green salad or some crusty bread.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, or microwave in short intervals, stirring occasionally, until heated through.

This bake can also be frozen for later enjoyment. Assemble the casserole, but do not sprinkle with cheese or bake. Wrap tightly in plastic wrap and then in foil. Freeze for up to 2 months. Thaw in the refrigerator overnight before baking. Sprinkle with cheese and bake according to normal instructions.

FAQs (Frequently Asked Questions)
