Overview
Home cooks who want air frying without a countertop gadget get it built into the convection oven of Cosmo's Lumin Collection gas range. Sealed burners under heavy cast iron grates handle the stovetop, and a fan circulates heat through the oven, which also offers a self-clean cycle.
Oven versatility leads here: convection, air fry and self clean cover a lot of cooking and cleanup in one cavity. Controls mix knobs with a touch panel. Install style is the open question, since the spec sheet lists slide-in while the category says freestanding.
Who it's for
Busy kitchens on gas where the oven gets used for roasting, baking and air frying in the same week get the most out of it. Households that need a longer warranty, or a range confirmed as freestanding, should look elsewhere.
Pros and cons
- Air fry mode built into the oven
- Self-clean oven cycle
- Convection fan for even heating
- Heavy duty cast iron grates
- Listed as slide-in, filed as freestanding
- Warranty limited to 1 year
- Burner BTU ratings not listed
- Heavy at 227 lb
Performance notes
Convection results come from the fan pushing hot air around food, which shortens cook times and evens browning, and air fry leans on that moving air to crisp food with less oil than frying. Sealed burners contain spills on the cooktop surface, and the self-clean cycle handles baked-on oven residue.
