Why this recipe works for budget families
The key to saving money on meals is buying own-brand ingredients, using leftovers creatively, and keeping things simple. This recipe costs around £1.80 per serving (for a family of four) if you use store-brand tuna, pasta, and milk. It’s also foolproof—no fancy techniques, just a few key steps that even a busy parent can follow. Plus, it’s flexible: swap the veg for whatever’s in the fridge, or add extra protein like beans or lentils if you’re watching calories.
The best part? It’s easy to double or triple for leftovers, which means you’ll have a meal ready for lunches or a quick dinner the next day. Just remember the Food Standards Agency’s rules on reheating and storing leftovers to avoid food waste.

Step-by-step instructions
- Prep the veggies first – Chop the onion and mince the garlic (or skip the garlic if you’re in a hurry). Heat a little oil in a pan over medium heat and cook the onion for 3–4 minutes until soft. Add the garlic and cook for another 30 seconds until fragrant. Set aside.
- Cook the pasta – Boil a large pot of salted water (use about 1 litre for 500g pasta). Cook the penne for 8–10 minutes until al dente (check the packet for timing). Drain, reserving ½ cup of pasta water.
- Mix the sauce – In a bowl, whisk together the plain pasta sauce, milk, and a splash of pasta water until smooth. Stir in the drained tuna, peas, and cooked onion/garlic. Season with salt and pepper to taste.
- Assemble the bake – Preheat the oven to 180°C (160°C fan). Grease a 23cm (9-inch) baking dish or use a greased baking tray. Spread the pasta sauce mixture evenly over the bottom. Top with the cooked pasta, then pour over any leftover pasta water to help it stick.
- Bake for 20–25 minutes – Cover with foil and bake for 15 minutes. Then remove the foil and bake for another 5–10 minutes until golden and bubbling. Let it rest for 5 minutes before serving.
- Serve warm – Cut into portions and enjoy with a side of steamed green beans (£0.50 for 200g) or a simple salad (£0.30 for a bag of mixed greens).

> Tip: How to save even more money
- Use leftover pasta – If you’ve already cooked pasta for another meal, save the drained pasta and mix it into the bake instead of buying fresh.
- Skip the garlic – If you’re short on time, just cook the onion and set it aside—it’ll still add flavour.
- Buy frozen veggies – Frozen peas and mixed veg are just as nutritious and often cheaper than fresh.
- Stretch it with beans – Add 100g of canned chickpeas (£0.30) for extra protein and bulk.

How to make this meal even cheaper
If you’re on a tight budget, here’s how to cut costs further without sacrificing taste:
Worked example: £1.50 meal for four
- Pasta: 500g own-brand pasta (£0.50) → £0.13 per serving
- Tuna: 200g own-brand tuna (£0.80) → £0.20 per serving
- Sauce & milk: 400ml own-brand pasta sauce + 200ml milk (£0.50) → £0.13 per serving
- Veggies: 1 onion (£0.20) + frozen peas (£0.20) → £0.05 per serving
- Total: £1.50 for four (or £0.38 per person).
How?
- Use cheaper cut tuna (e.g., tinned tuna in oil is slightly more expensive, so stick to water).
- Skip the sauce – Mix the tuna, pasta, and milk directly, then add a splash of pasta water to loosen.
- Use store-brand milk – It’s just as good and often cheaper.

Serving ideas for leftovers
This bake is perfect for meal prep—it reheats well and holds its shape. Here’s how to use up leftovers:
- Lunchbox meal – Serve with a side of wholemeal bread (£0.40 for a loaf) and a cucumber salad (£0.30 for a cucumber).
- Quick dinner – Add a sprinkle of grated cheese (£0.50 for 100g) and a handful of cherry tomatoes (£0.60 for 200g).
- Breakfast-for-dinner – Top with a fried egg (£0.30 each) and serve with toast.
> Tip: Store leftovers properly
- Cool quickly – Spread leftovers in a single layer on a tray to cool before storing in the fridge.
- Refrigerate within 1–2 hours – Follow the Food Standards Agency’s rules to avoid food poisoning.
- Eat within 48 hours – If reheating, ensure it’s steaming hot throughout before serving.

Freezing and reheating leftovers
If you’re not eating the bake within 48 hours, freeze it instead:
- Cool completely – Let it sit at room temperature for 1 hour before freezing.
- Portion into containers – Use airtight containers to prevent freezer burn.
- Freeze for up to 3 months – Label with the date.
- Reheat in the microwave – Thaw overnight in the fridge, then heat in a microwave-safe dish for 2–3 minutes, stirring halfway.
> Mistake to avoid ❌ Freezing while hot – This can cause ice crystals and make reheating messy. ✅ Freezing after cooling – Ensures even reheating and better texture.

Frequently asked questions
### How do I make this tuna pasta bake healthier?
To make it lower in calories, reduce the amount of milk (use just 100ml instead of 200ml) and skip the cheese. For more veggies, add grated carrot (£0.30 for 100g) or spinach (£0.50 for a handful). If you’re watching fat, use light pasta sauce (just add a splash of milk to thin it).
### Can I use frozen tuna instead of canned?
Yes! Frozen tuna in oil or water works fine, but drain it well and squeeze out excess liquid before mixing into the sauce. Frozen tuna is often cheaper than fresh and lasts longer in the freezer.
### What if my kids won’t eat tuna?
No problem! Swap the tuna for canned chicken (£0.80 for 200g) or chickpeas (£0.30 for 200g). For a vegetarian version, add grated zucchini (£0.40 for 100g) or mushrooms (£0.50 for 100g). The sauce will still hold together.
### How long does this bake last in the fridge?
According to the Food Standards Agency, cooked pasta bake should be eaten within 48 hours (2 days) if stored in the fridge. If you don’t finish it, freeze it instead—it’ll keep for up to 3 months and reheats just as well.
