A Midweek Marvel That Brings Everyone to the Table
Let’s be honest—some nights call for something simple, cozy, and made with ingredients you probably already have tucked away in your kitchen. That’s where this Cheesy Tuna Pasta Bake comes to the rescue. It’s warm, filling, cheesy (hello, melty cheddar!), and the kind of meal that feels like a hug in casserole form. Plus, it’s budget-friendly, freezer-happy, and kid-approved.
Now, I have to tell you—this is one of those dishes I grew up on. My mum would make it on busy weeknights when we had a bit of leftover cheese, a couple tins of tuna, and not much else in the fridge. Somehow, it always came out tasting like a treat. And now, I get to pass it on to you—with a few tweaks to make it even more delicious!
So grab your pasta, drain those tuna tins, and let’s dive in.
What You’ll Need:
Here’s your trusty cast of characters for this bake:
-
300g pasta (penne and fusilli both work great!)
-
2 x 160g tins tuna in spring water, drained
-
1 onion, finely diced
-
2 garlic cloves, minced
-
400g tinned chopped tomatoes
-
300ml milk
-
30g butter
-
30g plain flour
-
100g cheddar cheese, grated
-
1 tsp dried oregano
-
Salt & pepper, to taste
-
50g breadcrumbs (optional, but that crunchy topping? Yum!)
Step 1: Cook the Pasta
Start by getting your pasta on. Bring a large pot of salted water to a boil and cook your pasta until it’s just al dente—about 10 minutes should do the trick. Remember, it’ll keep cooking in the oven later, so don’t overdo it! Once it’s done, drain it and set it aside.
Quick Tip: Drizzle a bit of olive oil over the drained pasta to keep it from sticking together while you prep the rest.
Step 2: Sauté the Onion & Garlic
While your pasta’s cooking, go ahead and heat a splash of oil in a large skillet over medium heat. Add in the finely diced onion and sauté for about 5 minutes, until it’s soft and translucent. Toss in the garlic and cook for another minute—your kitchen should smell amazing right about now.
Step 3: Add the Tomatoes and Tuna
Now, pour in the chopped tomatoes and sprinkle in your oregano. Let that simmer gently for about 5 minutes to let the flavors come together. Then, gently stir in your flaked tuna. You don’t want to break it up too much—those little chunks of tuna are what make this bake so satisfying.
Coming up next: that dreamy cheese sauce, how to bring it all together, and why you might want to keep a second portion just for yourself. Ready for more? Let’s keep going!
Creamy Cheese Sauce, The Ultimate Bake, and Helpful Tips
Okay, here comes the really good stuff—the creamy cheese sauce that ties this whole dish together and makes it next-level comforting. This part’s easier than you might think, and once you master it, you’ll want to pour it on everything.
Step 4: Make the Cheese Sauce
In a medium saucepan, melt 30g of butter over medium heat. Once it’s melted, stir in the 30g of plain flour. You’re making a roux here—just keep stirring for a minute or two until it forms a smooth paste. Don’t rush this part—it’s what thickens the sauce and gives it that creamy base.
Next, slowly whisk in the milk. Go gradually and keep whisking to avoid lumps. Once it’s all in, cook the sauce over medium heat until it thickens up—this usually takes about 5 minutes. You’re aiming for a smooth, velvety consistency.
Now comes the good bit: stir in half of your grated cheddar cheese until it melts into the sauce. Give it a taste and season with salt and pepper. It should be creamy, cheesy, and just a little bit addictive.
Step 5: Mix Everything Together
In a large mixing bowl—or right in your baking dish if it’s big enough—combine your cooked pasta, the tomato-tuna mixture, and your lovely cheese sauce. Stir gently until everything is well coated.
At this point, it’s already smelling pretty delicious. But we’re not done yet!
Step 6: Top and Bake
Transfer everything to a greased baking dish. Sprinkle the remaining cheddar cheese over the top, and if you’re using breadcrumbs (and I highly recommend that you do), scatter those on too. It gives the bake a beautiful golden crust that’s crispy on top and creamy underneath. Bake it in a preheated oven at 200°C (fan) for about 20–25 minutes until the top is bubbly and golden.
Pro Tip: For an extra-crispy top, switch on the grill for the last 2 minutes. Just keep an eye on it—you want golden, not burnt!
Optional Add-Ins and Variations
Want to make it your own? Here are a few ideas:
-
Add Veggies: Stir in frozen peas, sweetcorn, or even a handful of spinach for a veggie boost.
-
Go Spicy: Add a pinch of chili flakes to the tomato sauce if you like a little heat.
-
Try Different Cheeses: A mix of cheddar and mozzarella is delicious, or swap in some parmesan for a sharper finish.

Your Questions Answered + A Cozy Conclusion
Let’s tackle a few common questions that pop up when it comes to making a Tuna Pasta Bake. Whether you’re a first-timer or just looking to improve your game, these FAQs have you covered.
FAQ: Cheesy Tuna Pasta Bake
1. Can I make this ahead of time?
Absolutely! Assemble the bake, cover it, and keep it in the fridge for up to 24 hours. Just bake it when you’re ready, adding 5–10 minutes to the cooking time.
2. Can I freeze it?
Yes! Once baked and cooled, freeze it in portions for up to 3 months. Reheat from frozen or defrost overnight and reheat with a splash of milk to keep it creamy.
3. What’s the best type of pasta to use?
Penne or fusilli hold the sauce really well, but shells and rigatoni are also great options. Just avoid very small shapes like macaroni—they can get a bit lost in the sauce.
4. Can I use tuna in oil instead of spring water?
You can, but make sure to drain it well. Tuna in oil will add a richer flavor, though some people find it a bit too oily in creamy dishes like this.
5. What can I use instead of breadcrumbs?
Crushed crackers, crushed cornflakes, or even panko make great alternatives. Or skip the topping altogether—it’s still delicious!
6. Is it kid-friendly?
Yes! It’s cheesy, mild, and comforting. If your kids don’t like tuna, try mixing it with a bit more cheese or sneaking in some mashed veg to soften the flavor.
7. How do I reheat leftovers?
Microwave with a splash of milk or pop it in the oven at 180°C covered with foil until warmed through. This helps bring the creaminess back to life.
