Why this recipe works
This baked tuna pasta recipe is the perfect dish to warm you up in those cold fall and winter months. It comes together in minutes once the pasta is cooked and then bakes for 25 minutes.
Because this dairy free tuna & pasta bake has quite a few canned items, it’s a great one to keep on hand when your fresh produce runs out and you haven’t quite made it to the store.
The flavours of this quick tuna pasta bake are what are going to keep you coming back for more. If you search tuna pasta bake ideas, you’ll likely find quite a few creamy tuna bakes. My tuna bake recipe doesn’t use that creamy aspect. Instead, it’s full of sweetcorn and tomato flavours, covered in a cheesy top. This tuna pasta bake tomato style is sure to become a quick favourite!
This was inspired by my Vegan Pasta Bake and Sausage Pasta Bake and pairs well with this amazing Three Bean Salad recipe.
Ingredients to make Tuna Pasta Bake
- Penne Pasta – I use gluten-free, but regular penne will work just fine in this tuna noodle casserole. If you have some spare try making my One Pot Pasta.
- Garlic Cloves – add a delicious flavour to the bake.
- Red Onion – is my favourite onion to use in my dinners.
- Canned Tuna – Make sure to drain the tuna from the cans. If you have some spare then also try my Canned Tuna Pasta or Tuna Pasta Salad.
- Sweetcorn – should also be drained.
- Passata – is pure tomatoes that have been pureed and strained. If you have any jars spare then try my famous Vegan Lasagne recipe.
- Dried Oregano – pairs great with tomato.
- Dried Basil – has a sweet and savoury flavour profile.
- Fresh Spinach – adds a great colour as well as nutrients to this dish.
- Grated Cheese – I use vegan cheese for this recipe to make it a dairy free pasta bake.
- Salt and Pepper – are used to finish off the flavours of this simple tuna bake.

Substitutions
- Penne Pasta – could be replaced by whatever pasta you have on hand. Macaroni, shells, fusilli or even spaghetti would work.
- Garlic Cloves – are best fresh, but can be replaced with minced or dried garlic if needed.
- Red Onion – Yellow or white onion would also work.
- Tuna – If you aren’t a tuna fan, try some canned chicken or salmon instead. But if you fancy another fish pasta recipe then try my Prawn Linguine.
- Vegetables – If you’d like to replace or add to the corn, you could try carrots, frozen peas, mushrooms, broccoli, etc.
- Passata – You can use tinned tomatoes, tomato purée or paste if you don’t have passata. You may need to adjust the amounts to produce the correct consistency.
Variations
- Spicy – add chopped jalapeno peppers or crushed red pepper flakes for a spicy tuna baked pasta.
- Deluxe – Broil this easy tuna pasta bake for the last 5 minutes or so to crisp up the cheese. You can add some extra veggies and serve up with some gluten free garlic bread for a deluxe meal.
- Kid friendly – If your kids aren’t tuna fans, swap it out for canned chicken. Crumble some potato chips on top for a fun treat!

How to make Tuna Pasta Bake
Step 1: Firstly, boil the pasta (per packet instructions).
Step 2: Next, dice the onion and crush the garlic.
Step 3: Once the pasta has cooked, drain and add to a large baking dish along with the onion, garlic, drained tuna, drained sweetcorn, passata, spinach, herbs, salt and pepper and mix together.
Step 4: Finally, top with grated cheese and bake for 25 minutes at 200C.
Hint: Broil or grill the tuna casserole for the last 5 minutes or so to crisp up the cheese nicely.
Leftovers
Store leftover tuna bake in an airtight container in the fridge for up to four days. You could also freeze it for up to three months. Make sure to reheat until piping hot throughout.
Recipe FAQs
Tuna and pasta together in a creamy sauce is something that can be found across centuries and countries. Tuna casserole itself seems to have become incredibly popular in the mid-1900s. It was a quick, cheap, easy, and delicious meal. When Cream of Mushroom soup became easily available, this dish became a staple in many homes.
It can! If you’re reheating a larger portion, I’d recommend the oven. If you’re just heating up a single-serve portion, the microwave will be great.
It depends. Some tuna bakes have a cream sauce. This can build up the calories quickly. My recipe is based on the noodles and tuna being covered in vegetables and some cheese. Definitely a healthier version of this classic recipe.
This tuna pasta bake is great with a nice green salad, Air Fryer Broccoli or your favourite veggie side.

Loved this recipe Easy to make and easy to adapt to the ingredients I had in the cupboard. Easy to adapt to a single person. I am so looking forward to other recipes
Thanks so much Ann 🙂
Excellent recipe, thanks! My kids aren’t really fussy anymore, but a Tuna Pasta Bake experience from some years ago made them wary of this one when I served it up.
Suffice to say – wariness now overcome! And a very positive endorsement from my wife too.
I used fresh basil leaves as I had some to hand – I respectfully think they lifted the flavours even more.
LOVE this, thank you Richard 🙂
Lovely recipe, my family really enjoyed it and I’ll definitely make it again, but I’d say that it’s more like 6 portions rather than 4. Thanks for the recipe!
Thank you Susie 🙂
