What You’ll Need: The Ingredient Lineup

• 250g (9oz) Penne Pasta: We’re using penne for its ability to hold onto the creamy sauce, but feel free to substitute with your favorite short pasta shape like fusilli or rotini.
• 400g (14oz) Canned Tuna in Water, Drained: Opt for tuna packed in water for a lighter bake. Make sure to drain it well to avoid a watery sauce. Chunk light tuna works beautifully, but albacore is also a great choice for a more robust flavor.
• 300ml (1 ¼ cup) Whole Milk: Whole milk provides the necessary richness for our creamy sauce. You can use semi-skimmed, but the sauce won’t be quite as luxurious.
• 150ml (⅔ cup) Heavy Cream: This is the secret ingredient for an extra decadent sauce! Don’t skimp on the heavy cream – it makes all the difference.
• 30g (2 Tbsp) Unsalted Butter: Butter forms the base of our roux, adding flavor and helping to thicken the sauce.
• 30g (2 Tbsp) All-Purpose Flour: The flour combines with the butter to create a roux, which is essential for a smooth and creamy sauce.
• 150g (5oz) Grated Mozzarella Cheese: Mozzarella is a classic melting cheese, providing that gooey, stretchy texture we all crave in a pasta bake.
• 50g (1 ½ oz) Grated Sharp Cheddar Cheese: A touch of sharp cheddar adds a lovely depth of flavor and complements the mozzarella perfectly.
• 1 Small Onion, Finely Chopped (≈80g / 3oz): The foundation of our flavor base, the onion adds a subtle sweetness and aromatic depth.
• 2 Cloves Garlic, Minced: Garlic is a must-have for any savory dish! It adds a pungent aroma and delicious flavor.
• 1 tsp (5ml) Dijon Mustard: A small amount of Dijon mustard adds a subtle tang that balances the richness of the sauce.
• 1 tsp (5ml) Lemon Zest: Brightens up the flavors and adds a fresh, zesty note.
• 1 tsp (5ml) Smoked Paprika: This is where the magic happens! Smoked paprika adds a wonderful smoky flavor that elevates the entire dish.
• ½ tsp (2.5ml) Chili Flakes: For a touch of heat! Adjust the amount to your preference.
• 150g (5oz) Frozen Peas, Thawed: Adds a pop of color and a touch of sweetness.
• 2 Tbsp (30ml) Olive Oil: Used for sautéing the onion and garlic, providing a flavorful base for the sauce.
• Salt and Freshly Ground Black Pepper to Taste: Essential for seasoning and enhancing all the flavors.
• 30g (¼ cup) Panko Breadcrumbs: Panko breadcrumbs create a wonderfully crunchy topping.
• 1 Tbsp (15ml) Melted Butter (for Breadcrumbs): Helps the panko breadcrumbs turn golden brown and crispy.
• Fresh Flat-Leaf Parsley, Chopped: For a fresh, vibrant garnish.
• 1 Tbsp (15ml) Lemon-Infused Olive Oil: A finishing drizzle that adds a bright, citrusy aroma and flavor.

Let’s Build Your Dreamy Creamy Tuna Pasta Bake: Step-by-Step Instructions

1. Preheat & Prep: Begin by preheating your oven to 180°C (350°F). This ensures even cooking and a beautifully browned top. While the oven heats, lightly grease a 22 x 33 cm (9 x 13 in) baking dish. Using a ceramic dish helps distribute heat evenly, but any oven-safe dish will work.
2. Cook the Pasta: Bring a large pot of salted water to a rolling boil. Add the penne pasta and cook for 2 minutes less than the package directions – usually around 8 minutes. This is crucial! The pasta will continue to cook in the sauce, and we want it al dente, not mushy. Drain the pasta thoroughly and set it aside.
3. Sauté Aromatics: In a large skillet, heat the olive oil over medium heat. Add the finely chopped onion and sauté for 3-4 minutes, until it becomes translucent and softened. This builds the flavor base of the sauce. Then, add the minced garlic and cook for just 30 seconds more – you want it fragrant, but not browned, as burnt garlic can become bitter.
4. Create the Roux: Sprinkle the all-purpose flour over the sautéed onions and garlic. Whisk constantly for 1 minute to create a roux. This is the foundation of our creamy sauce, and whisking prevents lumps.
5. Build the Creamy Sauce: Slowly whisk in the milk and heavy cream, continuing to whisk constantly to prevent lumps from forming. Start with a small amount of liquid and gradually add more as it thickens. Simmer for 4-5 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon. This indicates it’s ready to receive the other flavors.
6. Season & Melt Cheese: Remove the skillet from the heat. Season the sauce generously with salt, freshly ground black pepper, Dijon mustard, lemon zest, smoked paprika, and chili flakes. The Dijon adds a subtle tang, the lemon zest brightens the flavors, the smoked paprika provides a smoky depth, and the chili flakes offer a gentle warmth. Stir in the grated mozzarella and cheddar cheese until they are completely melted and the sauce is smooth and creamy.
7. Combine & Transfer: Gently fold the cooked penne pasta, drained tuna, and thawed peas into the creamy cheese sauce. Be careful not to overmix, as you want to keep the pasta intact. Transfer the entire mixture to the prepared baking dish, spreading it out evenly.
8. Prepare the Crunchy Topping: In a small bowl, combine the panko breadcrumbs with the melted butter and a pinch of smoked paprika. This creates a golden, flavorful crust. Sprinkle the breadcrumb mixture evenly over the top of the pasta bake.
9. Bake to Golden Perfection: Bake uncovered in the preheated oven for 25-30 minutes, or until the breadcrumb crust is golden brown and the sauce is bubbling around the edges. The bubbling sauce indicates that the bake is heated through and the flavors have melded together.
10. Rest & Serve: Remove the pasta bake from the oven and let it rest for 5 minutes before serving. This allows the bake to set slightly, making it easier to slice and serve.

Why This Tuna Pasta Bake Works: The Science of Creaminess

The secret to a truly creamy tuna pasta bake lies in the roux. This classic French technique – cooking flour in butter – creates a thickening agent that allows the milk and cream to emulsify, resulting in a smooth, velvety sauce. The cheese adds richness and flavor, while the Dijon mustard and lemon zest provide a balanced acidity that cuts through the richness. The smoked paprika and chili flakes add complexity and a subtle kick, elevating the dish beyond a simple comfort food.

Tips for the Perfect Tuna Selection

When choosing your canned tuna, opt for tuna packed in water rather than oil. This allows you to control the amount of fat in the dish. Flake the tuna gently with a fork before adding it to the sauce to ensure it’s evenly distributed. High-quality tuna will have a milder flavor and a firmer texture.

Customizing Your Bake: Variations & Additions

Feel free to get creative with this recipe! Add other vegetables like chopped bell peppers, mushrooms, or spinach. A sprinkle of Parmesan cheese on top of the breadcrumbs adds extra flavor. For a spicier kick, increase the amount of chili flakes or add a dash of hot sauce. You can also substitute different types of pasta, such as rotini or fusilli.
