How these supermarkets differ for meal prep

Aldi

A short list done cheaply. Aldi carries one or two options per line rather than ten, which is a constraint when you want a specific product and an advantage when you just want the week bought quickly.

Aldi lists a dedicated Higher Protein Food & Drink category online, so protein-led products are grouped rather than scattered through the aisles.
The Slimwell range groups lower-calorie prepared products in one place.
Specially Selected is the premium own-label tier; Everyday Essentials is the value tier.

Lidl

Lidl is the discounter to pick when the plan leans on high-protein dairy, because its own-brand dairy line covers that specifically rather than incidentally.

Milbona is the own-brand dairy label, and its high-protein line is unusually broad for a discounter: High Protein Skyr, High Protein Greek Style Yoghurt, Fat Free High Protein Yoghurt and a High Protein Drink are all listed as own-brand.
Lidl groups these under a dedicated High Protein category online rather than leaving them in general dairy.
Deluxe is the premium own-label tier.

Asda

Asda is the one to choose when the whole basket has to come from the value tier, because Just Essentials reaches into fresh meat and fish rather than stopping at cupboard goods.

Just Essentials by Asda spans fresh meat, fish and poultry, bakery, frozen and cupboard staples — the value tier is not limited to ambient goods, which matters when protein is the expensive part of a plan.
Asda launched a high-protein ready-meal range in 2026 formulated to be high in protein and to carry at least 80g of fruit or vegetables per 250g meal.
Asda Rewards pays into a cashback wallet rather than discounting at the till, so it does not reduce the price of this week’s shop.

What We Are Comparing

The comparison is based on a standard one-person, one-week high-protein meal prep basket: 1 kg chicken breast, 12 eggs, 500 g 0% Greek yogurt, 1 kg rolled oats, 1 kg brown rice, 4 tins tuna in spring water, 500 g frozen broccoli, 200 g baby spinach, 300 g salmon fillets, and 500 g wholemeal bread. This basket provides approximately 5–6 days of main protein sources for 1,600–2,000 kcal/day eating.

Prices are own-brand or equivalent where possible, using in-store and online prices collected in February 2025. That is far enough back that the totals below should be read as a snapshot, not as this week’s shelf price — UK grocery prices have moved since, and they have not moved evenly across the supermarkets.

Supermarket Rankings: Cheapest To Most Expensive

Approximate total for the standard basket at each supermarket, priced in February 2025. Treat the order as the finding and the totals as indicative: the gap between the discounters and the big four has been consistent for years, whereas the absolute figures have almost certainly risen since they were collected. Check shelf prices before you plan a shop around them.

1st — Aldi: ~£28–32. Consistently the cheapest on almost every staple in the basket. The only limitation is that Aldi does not always stock fresh salmon, so this may push some shoppers to supplement elsewhere.
2nd — Lidl: ~£29–33. Very similar to Aldi and competitive on most items. Lidl's Deluxe range offers slightly better quality for a small premium. Lidl tends to have slightly better fish and seafood availability than Aldi.
3rd — Iceland: ~£30–34. Iceland's frozen protein range is its strongest suit. Frozen chicken breast and salmon are genuinely cheap, and Iceland's multi-buy deals are excellent. Fresh produce range is much more limited, which is a drawback.
4th — Asda: ~£35–40. Solid own-brand range that is cheaper than Tesco on several items. Asda Rewards (the loyalty scheme) can narrow the gap with Aldi for frequent shoppers.
5th — Tesco: ~£38–45 (or ~£34–40 with Clubcard). Tesco's Clubcard prices bring it much closer to Asda and occasionally within £5 of Aldi on a full basket. Without Clubcard, it is noticeably more expensive.
6th — Morrisons: ~£40–46. Own-brand quality is good, and the butcher and fishmonger counters offer fresh options not found elsewhere. However, it is consistently more expensive than Aldi and Lidl on staples.
7th — Sainsbury's: ~£43–50. Highest cost in the comparison. The Taste the Difference range is genuinely excellent, but for meal-prep staples, the own-brand range simply does not match the value of Aldi or Lidl.

Where Each Supermarket Stands Out

Aldi and Lidl win on price but have narrower ranges and limited online delivery. They are best for shoppers who can visit in person weekly and are comfortable with slightly less variety.

Iceland is the standout for frozen protein. Their frozen chicken breast, salmon, and prawns are exceptional value, and the quality of their frozen fish is underrated. If you are happy to meal prep entirely from frozen protein, Iceland can be cheaper than Aldi.

Tesco and Asda win on range, online service, and loyalty scheme value. For busy professionals who shop online, Tesco with Clubcard is the pragmatic choice — the price gap versus Aldi shrinks to 10–15% on a full basket with Clubcard Prices active.

Morrisons is best for shoppers who want a mix of budget staples and fresher or higher-quality items. Its Market Street butcher counter means you can buy chicken thighs and lean mince freshly prepared, which some meal preppers prefer.

The Hybrid Strategy: Maximum Savings

The most cost-effective approach for dedicated meal preppers is to use two supermarkets: Aldi or Lidl for the core staples (chicken, eggs, oats, rice, frozen veg, tinned tuna) and Tesco, Asda, or Morrisons for specific items that the discounters do not stock reliably (fresh salmon, certain vegetables, specialist health foods).

This hybrid approach typically brings the weekly total closer to the budget end while maintaining the full range of a larger supermarket when needed. Prices vary and change frequently — check current shelf prices before shopping.

Frequently Asked Questions

Which UK supermarket is cheapest for meal prep?

Aldi and Lidl are consistently the cheapest, with a standard high-protein weekly basket typically costing significantly less than the big four supermarkets. Iceland is competitive for frozen proteins. Asda is the best of the big four for budget shopping, followed by Tesco with Clubcard. Sainsbury's and Morrisons are typically the most expensive. Prices vary and change regularly — check current shelf prices.

Is Iceland good for meal prep?

Yes, especially for frozen protein. Iceland's frozen chicken breast, salmon fillets, and prawns are very competitively priced and nutritionally equivalent to fresh. The fresh produce range is limited, but for a protein-heavy meal prep strategy, Iceland is excellent value.

Should I shop at Aldi or Lidl for meal prep?

Both are excellent. Aldi tends to be marginally cheaper on chicken and oats; Lidl typically has better fish and dairy availability in many stores. Shopping at whichever is closest to you will produce near-identical results — the price difference between the two is small on a standard basket.

Do I need to shop at multiple supermarkets?

Not necessarily. A pure Aldi or Lidl shop covers most meal prep staples well. The hybrid strategy (discounters for core staples, a larger supermarket for fresh salmon or specialist items) saves a little more, but only makes sense if you pass both on your regular route.
