Ingredients for budget creamy tuna pasta bake
- Pasta – Short pasta like penne, spirals, or shells works best as it holds the sauce well.
- Tinned tuna – Cheap, convenient, and adds protein. Use tuna in springwater or oil, drained.
- Milk – Forms the base of the creamy sauce without needing cream.
- Butter – Adds richness and helps create the sauce.
- Flour – Thickens the sauce and gives it a smooth texture.
- Cheese – Adds flavour and helps create a golden top when baked.
- Garlic – Adds depth to the sauce. Fresh is best.
TIP: Frozen peas or corn are a great low cost way to bulk this out.
How to make budget creamy tuna pasta bake
- Preheat your oven to 180°C. Cook the pasta in salted boiling water until just al dente, then drain and set aside.
- In a large pan, melt the butter over medium heat. Add the garlic and cook for 30 seconds until fragrant.
- Add the flour and cook for 1 minute, stirring, to form a paste. Slowly pour in the milk, whisking as you go to keep the sauce smooth.
- Cook the sauce for 3 to 5 minutes, stirring, until it thickens. Stir through half of the cheese.
- Add the drained tuna and cooked pasta to the sauce. Mix well until everything is coated.
- Transfer to a baking dish, sprinkle over the remaining cheese, and bake for 15 to 20 minutes until hot and golden on top.
Tips
- Don’t overcook the pasta. Keep it just al dente so it doesn’t go soft in the oven.
- Add the milk slowly. This keeps the sauce smooth and lump free.
- Stir the sauce constantly. Prevents sticking and gives a better texture.
- Drain the tuna well. Stops the bake from becoming watery.
- Use a mix of cheeses if you have it. Adds more flavour.
- Grill for the last few minutes if you want a more golden top.
Ideas to bulk it out
- Stir through frozen peas, corn, or mixed vegetables
- Mix in sautéed mushrooms or spinach
- Top with breadcrumbs for extra texture
- Swap tuna for leftover chicken if preferred
Serving suggestions
Serve with a simple side salad or steamed vegetables to balance the richness. A slice of toast or garlic bread works well if you want to make it go further. Sprinkle over fresh herbs like parsley or chives if you have some in the fridge for a fresh finish.
Storage
Fridge: Store in an airtight container for up to 3 days.
Reheat: Reheat in the oven at 180°C until hot, or microwave in portions. Add a splash of milk if it looks dry.

Budget Creamy Tuna Pasta Bake
Ingredients
- 500g dried pasta, such as penne or spirals
- 50g butter
- 2 teaspoons crushed garlic
- ⅓ cup plain flour
- 2 ½ cups milk
- 1 ½ cups grated cheese
- 425g can tuna, drained
You will also need
- Salt and pepper, to taste
Instructions
- Preheat oven to 200°C (180℃ fan forced). Cook the pasta in well salted boiling water until just al dente. It will continue cooking in the oven, so don’t overcook. Drain and set aside.
- In a large pan, melt the butter over medium heat. Add the crushed garlic and cook for 20 to 30 seconds, stirring, until fragrant. Keep the heat moderate so it doesn’t burn.
- Add the flour and stir constantly for 1 minute to form a smooth paste. This removes the raw flour taste and helps create a thick, creamy sauce.
- Gradually pour in the milk, whisking as you go to keep the sauce smooth and lump free. Continue stirring for 3 to 5 minutes until the sauce thickens enough to coat the back of a spoon. Season with salt and pepper.
- Stir through about half of the cheese until melted. Add the drained tuna and cooked pasta, then mix well so everything is evenly coated in the sauce.
- Transfer to a baking dish and spread out evenly. Sprinkle over the remaining cheese, then bake for 12 to 15 minutes until hot and lightly golden on top.
Notes
- Measurements: We use Australian tablespoons and cups: 1 teaspoon = 5 ml, 1 tablespoon = 20 ml & 1 cup = 250 ml.
- Add fresh herbs if you have them: Parsley, chives, or even a bit of basil stirred through at the end or to garnish with lifts the flavour.
- Use whatever cheese you have: Tasty, cheddar, or a mix all work. Pre-grated is fine for budget cooking.
- Add a crunchy topping: Sprinkle breadcrumbs, crushed crackers or crushed corn chips over the top before baking for extra texture.
- Make it ahead: Assemble the bake, cover, and refrigerate. Bake when ready to eat. Add a few extra minutes to the cooking time.
- Balance the richness: A squeeze of lemon juice before serving helps cut through the creaminess.
- Use up leftovers: This is a great base for using small amounts of veg sitting in the fridge.
