We analysed the Amazon.co.uk subcategory Au Gratin Dishes and kept only products with at least 200 reviews and 4.3 stars. Just five listings clear that bar, and only one of them recorded measurable sales in the period — so read this as a map of a very thin niche rather than a bestseller list.
The only entry with any recorded sales at all in the period, and the largest of the small dishes here at 20 oz — the £37.81 covers four of them, so roughly £9.45 each.

A four-piece set in matte black at 16 oz per dish — well reviewed at 4.7 stars, but its bestseller rank above 1.6 million says almost nobody buys it here.
The only single dish in this comparison and the cheapest way in at £21, from the French maker with the strongest name in this category.
A two-piece teal set at £29.41 and the most reviewed listing here with 1,541 ratings, though its price fell 32% over the observed period.
The highest rated at 4.8 stars and the outlier in intent — a seasonal Spode piece that sells around Christmas rather than a workhorse dish.

A gratin dish is defined by its surface area: the browned crust of cheese and breadcrumbs is the whole point, and a deep casserole steams the top instead of crisping it. Every dish here is under two inches deep for that reason.
These are portion dishes, quoted in ounces rather than litres — 16 oz feeds one generously, 20 oz stretches to two as a side. Work out how many you actually need at the table before buying a set of four.
Gratin dishes come out of the oven at full heat and go straight to the table. Short moulded ears are common; check they stand proud enough for oven gloves rather than fingertips, because there is no lid to grab.
Finishing a gratin usually means a few minutes under the grill, and then the dish often goes into the fridge with leftovers. Glazed stoneware handles that better than thin earthenware, but nothing here likes going from freezer to hot oven.
Nobody decants a gratin — it is served in the dish it was baked in. That makes the glaze and colour a functional choice here in a way it is not for a roasting tin, and it explains why a seasonal Spode piece sits in this top five.
Four small oval dishes take more cupboard space than one large baker and rarely nest well because of the handles. If you cook individual portions once a year, a single dish is the honest choice.
Au Gratin Dishes is a very small Amazon.co.uk subcategory, and only five listings in it reach 200 reviews and 4.3 stars. We would rather show a short, honest comparison than pad it out with products that fail our own filter.
Four of the five recorded no measurable revenue in the period, with bestseller ranks between 1.2 and 2.5 million. They are mostly US imports carried by third-party sellers. Good ratings, but very little actual UK demand behind them.
A gratin dish is shallow and usually oval, sized for one or two portions, and built so a crust browns across the whole surface. A baking or casserole dish is deeper and larger, which suits stews and bakes but works against a crisp top.
The products are ordered by estimated monthly revenue per ASIN, not by star rating and not by bestseller rank. Only products with at least 200 reviews and an average of 4.3 stars were included. In a niche this thin, revenue is what separates a listing that sells from one that merely exists.
The score is not our own hands-on test. It is calculated transparently from public Amazon data: 75% from the average star rating and 25% from the number of reviews, weighted logarithmically. The ranking order itself comes from estimated monthly revenue per ASIN. Prices, ratings and review counts were retrieved from Amazon.co.uk on 22 July 2026 and can change at any time.
