Aldi vs Tesco for Meal Prep: Which Supermarket Is Better?

Price Comparison: The Staples

For the core meal-prep staples, here is how Aldi and Tesco compare on approximate 2025 own-brand prices:

• Chicken breast (1 kg): Aldi ~£3.49 vs Tesco ~£5.49 (or ~£4.49 on Clubcard). Aldi wins by a significant margin.
• Eggs (12 large, free range): Aldi ~£2.59 vs Tesco ~£2.80–£3.20. Aldi cheaper, though Tesco regularly has Clubcard deals.
• 0% Greek yogurt (500 g): Aldi ~£1.09 vs Tesco ~£1.20. Aldi marginally cheaper.
• Rolled oats (1 kg): Aldi ~£0.69 vs Tesco ~£0.85. Aldi wins.
• Frozen broccoli (1 kg): Aldi ~£0.95 vs Tesco ~£1.00. Essentially the same.
• Tinned tuna (4 × 145 g): Aldi ~£1.99 vs Tesco ~£2.50. Aldi cheaper by roughly 25%.
• Brown rice (1 kg): Aldi ~£0.89 vs Tesco ~£1.20. Aldi noticeably cheaper.
• Salmon fillets (2 × 130 g): Aldi ~£2.79 vs Tesco ~£3.50 (Clubcard). Aldi cheaper, Tesco competitive on Clubcard.

Overall Cost for a Full Meal Prep Week

A full week of high-protein meal prep groceries (for one person, approximately 1,800 kcal per day, 150 g+ protein) typically costs £35–42 at Aldi and £42–52 at Tesco (with Clubcard) — a saving of £7–10 per week at Aldi, or £350–500 per year.

Tesco's Clubcard scheme narrows the gap considerably. If you shop at Tesco with an active Clubcard, you can close the price difference on chicken, salmon, and dairy by 20–30%. For regular large shops, the Tesco Clubcard makes the price gap feel smaller in practice than the list prices suggest.

Quality and Range Comparison

Aldi's chicken breast is well-regarded — it is typically British or European sourced, with a similar quality to Tesco's mid-tier range. Taste tests between Aldi and Tesco own-brand chicken, eggs, and Greek yogurt consistently find no meaningful difference in quality for everyday cooking.

Where Tesco clearly wins is range. Tesco stocks a wider variety of lean proteins (turkey steaks, cod fillets, prawns, tofu), a larger frozen vegetable selection, more specialist items (protein yogurts, low-calorie sauces, brown rice pouches), and items that Aldi does not stock permanently. Aldi's "Specialbuys" rotation means some items are only available for a week or two — planning around Aldi requires more flexibility.

Convenience and Availability

Tesco has roughly three times as many UK stores as Aldi and offers a full online grocery service with same-day or next-day delivery. Aldi's online ordering is more limited — click-and-collect is available but home delivery has patchy coverage outside major cities. For urban shoppers, this rarely matters; for rural areas, Tesco's reach is a genuine advantage.

Both stores have strong in-store availability of the core meal-prep staples. Aldi's reduced-to-clear section (usually after 6 pm) is worth checking for heavily discounted fresh chicken, fish, and vegetables.

The Verdict: Which Should You Choose?

If minimising cost is your top priority: Aldi wins. The savings are real — especially on chicken, oats, rice, and tinned fish — and the quality is genuinely comparable to Tesco for standard meal-prep ingredients.

If you value flexibility and range: Tesco is worth the modest extra cost, especially if you use Clubcard Prices consistently. The wider protein range makes it easier to add variety, and the full online service is convenient for busy weeks.

Many experienced meal preppers use both: Aldi for staples (chicken, oats, eggs, rice, frozen veg) and Tesco (or Sainsbury's) for specific items Aldi does not stock. This hybrid approach captures most of Aldi's savings while keeping access to a full range.
