The £20 Weekly Meal Plan for a Family of Four

Quick Summary

£20 feeds a family of four for 7 days — breakfast, lunch, and dinner

Complete shopping list with every item costed from Aldi/Lidl

Batch cooking on Sunday (45 mins) covers most of the week

1,800-2,000 calories per adult with 65-80g protein per day

Short Answer: A £20 weekly meal plan for a family of four is achievable by shopping at Aldi or Lidl, using budget proteins (chicken thighs, eggs, lentils, chickpeas), batch cooking on Sunday, and using every leftover. It's tight but balanced — roughly 1,800-2,000 calories and 65-80g protein per adult per day.

Yes, £20. Seriously.

Before you scroll away thinking this is going to be beans on toast for seven days — it's not. This is a proper meal plan with variety, nutrition, and meals your kids will actually eat.

The trick isn't buying less food. It's buying the right food, from the right places, and using everything you buy.

All prices are based on Aldi and Lidl UK prices as of early 2026.

How This Works

Batch cooking is essential. You're not cooking from scratch three times a day — that would take forever. Here's the prep schedule:

Sunday evening (45 minutes):

Roast all the chicken thighs on one tray
Cook a big pot of brown rice
Boil 6 eggs
Make the red lentil dhal (double batch — lunch on Wednesday sorted)

Wednesday evening (20 minutes):

Cook the pasta in bulk (use half for dinner, save half for Thursday lunch)
Blend leftover dhal into soup

That's it. Everything else is quick assembly — wraps, toast, reheating.

Tips to Stay Under £20

Buy frozen veg, not fresh. It's cheaper, lasts longer, and is actually picked and frozen at peak nutrition
Chicken thighs, not breasts. Thighs are half the price and taste better (more fat = more flavour)
Dried lentils, not tinned. 500g of dried lentils makes about 1.2kg cooked. A tin gives you 240g for the same price
Don't waste anything. Chicken bones make stock. Broccoli stalks go in soup. Stale bread becomes French toast
Check the reduced section. Go to Aldi or Lidl after 6pm for yellow-sticker bargains — especially meat and bread

Nutrition Check

This plan gives each adult approximately:

Calories: 1,800-2,000 per day
Protein: 65-80g per day
Fibre: 25-30g per day

Kids (age 5-10) will eat smaller portions and hit roughly 1,200-1,500 calories, which is about right.

It's not a bodybuilder diet. But it's balanced, varied, and miles better than living on chicken nuggets and takeaways.

What If You Have a Bit More to Spend?

If you can stretch to £25-30, add:

A bag of frozen berries for porridge (£1.50)
Tinned tuna for extra protein (£1.00)
A block of peanut butter (£1.50) — lasts weeks and adds protein to breakfasts
Extra fruit for snacking (£1-2)

Every extra pound makes a difference, but the base plan at £20 gives you everything you need.

Frequently Asked Questions

Is £20 a week enough food for a family of four?

Yes, but it's tight. You'll be cooking everything from scratch, using budget proteins (lentils, eggs, chicken thighs), and batch cooking to avoid waste. The nutrition breakdown gives each adult 1,800-2,000 calories and 65-80g protein per day.

What supermarket is cheapest for a £20 weekly shop?

Aldi and Lidl are consistently the cheapest for this type of shop. This plan is costed entirely from their prices. Asda Smart Price ranges are a decent alternative if there's no Aldi or Lidl nearby.

Can I do this without batch cooking?

You can, but it's harder. Batch cooking on Sunday takes 45 minutes and saves you 2-3 hours of cooking during the week. Without it, you'd need to cook from scratch every day, which isn't realistic for most working families.

What if I have more to spend?

At £25-30, add frozen berries for porridge, tinned tuna for extra protein, peanut butter (lasts weeks), and more fruit for snacking. Check our £30 meal plan for the upgraded version.
