Supermarket Tortilla Taste Test: Unveiling the Best and Worst Spanish Omelettes
In a quest for egg-cellence, we embarked on a thorough taste test of supermarket tortillas, evaluating them for flavour, texture, and ingredient quality. This review highlights which options deliver a plump, gooey experience reminiscent of fresh-from-the-pan cooking and which fall short as soggy disappointments.
The Testing Process and Key Findings
All tortillas were sampled both hot and cold, with many proving more enjoyable when gently reheated in a pan. Judgments were based on taste and texture, ranging from dense, firmly set eggs to the soft, squidgy centres that define an ideal tortilla. While all products were relatively minimally processed, a lack of transparency regarding ingredient origins was noted. However, many earned extra praise for using free-range eggs. Production locations varied between the UK and Spain, but this did not always correlate with superior quality. Although supermarket tortillas cannot fully replicate a homemade experience, the top contenders come surprisingly close.
Top Picks: The Best Supermarket Tortillas
Best Overall: Sainsbury’s Taste the Difference Spanish Tortilla with Flaked Pimentón
Priced at £3.50 for 300g (£1.17 per 100g), this small, plump tortilla features beautiful caramelisation and red specks from pimentón. It boasts a marvellously gooey texture, even when cold, with large pieces of floury potato. Made with free-range eggs and packed in Spain, it earns a five-star rating for its soft-set perfection.
Best Bargain: M&S Spanish Potato & Onion Tortilla
Available for £4.50 for 600g (75p per 100g) in-store only, this pale yellow, well-caramelised tortilla is the largest in the test.

Other Notable Contenders

Mid-Range and Lower-Rated Options
Asda Tortilla
At £2.98 for 500g (60p per 100g), this pale yellow, evenly caramelised tortilla is firmly set with fluffy potatoes. Highly seasoned and oily, it uses free-range eggs and a blend of sunflower and olive oils, earning three stars.
Unearthed Spanish Chorizo Tortilla
Available for £3.25 for 250g (£1.30 per 100g) at Ocado and Tesco, this fat, small tortilla is well-caramelised with a soft set and generous chorizo distribution. Made with free-range eggs and Spanish pork, it loses a star due to unclear welfare credentials.

Morrisons Spanish-Style Potato & Onion Tortilla
At £3 for 500g (60p per 100g), this saffron-yellow option has even caramelisation and soft potato but is lightly seasoned and dry. It improves when reheated and is one of the most economical free-range egg omelettes, rated two stars.
Co-op Spanish Tortilla
Priced at £3.35 for 250g (£1.34 per 100g), this nicely formed tortilla has a light colour and high potato-to-egg ratio with fresh onion taste. Well-seasoned but less tasty than other small options, it receives two stars.
