OXO Obsidian Carbon Steel Roaster Pan with Rack
Lower PFAS concern, carbon steel roaster pans typically carry minimal fluorochemical risk.
OXO's carbon steel roaster pan uses bare or seasoned carbon steel with no nonstick coating, meaning no Teflon-type coating or Teflon-family coating are expected. OXO does not publicly disclose PFAS use on this product, but the material itself, uncoated carbon steel, presents lower concern than coated nonstick cookware.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
This roaster is carbon steel, an iron-carbon alloy with no synthetic polymer coatings or ceramic glazes that typically introduce leaching hazards. Carbon steel does not contain Teflon-type coating, silicone, or enamel finishes that can degrade under high heat or prolonged use. The material is chemically inert across normal cooking temperatures and does not off-gas volatile compounds. Seasoning (oil polymerization on the surface) is the primary finish, which is food-safe once established.
The brand's record and disclosure
OXO has not published detailed safety certifications or third-party testing results for this specific roaster pan. The brand does not maintain a public PFAS reduction commitment or disclosure statement, which is typical for cookware manufacturers outside the premium/direct-to-consumer segment. No recalls or documented safety complaints appear in CPSC or FDA databases for this model. The manufacturer is headquartered in the US and subject to standard FDA cookware regulations.
How it compares in its category
Carbon steel roasters are among the lowest-chemical-risk options compared to non-stick coated pans (which carry Teflon-type coating and fluorochemical risk), enameled cast iron (glaze contamination with lead/cadmium is possible though rare in US brands), or aluminum roasters (marginal leaching risk, especially acidic foods). This OXO model sits in the middle price tier and avoids both budget bare-steel rust management and premium enamel or ceramic finishes. Stainless steel roasters are chemically equivalent but typically heavier and less heat-responsive.
If you buy it
Season the pan before first use by applying a thin layer of high-smoke-point oil (vegetable, grapeseed, or avocado) and baking it at 450°F for 15 minutes; repeat 3-4 times. Hand-wash only; dishwashers will strip seasoning. Dry immediately after washing to prevent rust. Use oven temperatures up to 500°F safely; the rack's handles should not exceed stovetop temperatures. Re-season occasionally if cooking acidic foods (tomatoes, wine) which erode the protective oil layer. Replace if rust develops in pitting patterns that cannot be scoured clean.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Iron leaching
Carbon steel can leach small amounts of iron into acidic foods (citrus, vinegar, tomato-based dishes) over time. This is not a toxicological hazard for most people but may affect taste and iron-sensitive individuals should verify tolerance. Proper seasoning reduces leaching significantly.
Rust formation if maintenance is poor
Unseasonded or poorly dried carbon steel develops surface rust quickly in humid environments. Rust itself is not acutely toxic but can flake into food and degrades the cooking surface. This is a maintenance issue, not an inherent material hazard, and is easily prevented with proper care.
Lead or cadmium in glaze (N/A for this product)
This product is bare carbon steel with no ceramic or enamel coating, so glaze contamination is not a concern. The seasoning is oil-based and contains no pigments or colorants.
Teflon-type coating or fluorochemical non-stick coatings
Carbon steel roasters do not use Teflon-type coating, silicone, or fluorinated non-stick finishes. This eliminates fume risk from overheating coatings and rules out per- and polyfluoroalkyl substance (PFAS) leaching from the pan surface itself.
Aluminum leaching (N/A for this product)
This roaster is carbon steel, not aluminum, so aluminum-specific leaching concerns do not apply. The rack (if aluminum) poses minimal risk from passive contact with food.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
