OXO Obsidian 12" Carbon Steel Frying Pan Review: Wirecutter's Best Pick Tested

Product Overview

The Obsidian line is OXO's entry into carbon steel cookware — a category long dominated by French brands like De Buyer and Matfer Bourgeat. The pan is stamped from carbon steel (roughly 99% iron, 1% carbon), which puts it in the same material family as cast iron but rolled thin enough to heat quickly and weigh half as much.

The 12" is the largest standard size in the line (also available in 8" and 10") and the one best suited to family cooking — it has a wide, flat cooking surface and slightly flared walls that make tossing food easy. OXO includes a removable silicone handle sleeve, a detail the brand uses to distinguish the Obsidian from bare-handled competitors.

The factory pre-seasoning is a thin baked-on layer of oil. It protects against rust in transit and lets you cook on the pan from day one — but it is a starting point, not a fully developed nonstick surface.

Performance & Real-World Use

Carbon steel heats up noticeably faster than cast iron and more evenly across the cooking surface, which rewards cooks who know how to manage temperature but can catch newcomers off guard. The pan goes from room temperature to ripping-hot in two or three minutes on medium-high. Overshooting is a common early mistake.

For searing — steaks, pork chops, chicken thighs — the Obsidian performs as well as cast iron. Heat retention isn't quite at cast iron levels, but for a home stove that's rarely a limiting factor. The flared 12" walls give you plenty of room to sear without steaming, and the pan is light enough to shake and toss without effort.

Eggs and delicate fish behave differently depending on where you are in the seasoning journey. With the factory layer, expect some sticking on the first few cooks. After four to six uses with higher-fat cooking (bacon, sautéed vegetables in oil, pan sauces), the patina builds and release improves meaningfully. Cook Culture's head-to-head comparison of the OXO vs. a Matfer Bourgeat found the OXO competitive on seasoning build-up and notably more comfortable in the hand — conclusions that line up with broader reviewer consensus.

Oven use works well. The 660°F ceiling is useful for reverse sears and finishing thick cuts, though you'll need to remove the silicone sleeve first (its limit is 428°F). The sleeve itself slides on and off quickly when the pan is cold, but becomes fiddly and hot to reattach mid-cook.
