Small households, busy weeknights, or anyone tired of babysitting a deep fryer will appreciate the time-savings and cleanup benefits. Ready to replace several appliances with one smart unit?

Who This Is For
Parents juggling snacks and school lunches, apartment dwellers with limited counter space, and home cooks who want the crisp texture of frying without the oil will all find value here. The 24 QT cavity fits a family sheet pan or multiple racks, making it useful for meal prep, reheating leftovers, and small dinner parties.
Look for this unit if you want convection crisping, a stainless steel exterior that tolerates daily use, and accessories included so you can start cooking the same day.
Key Features & Real-World Use
- 10-in-1 functionality – Air fry, bake, roast, toast, broil, dehydrate, warm, and more, using the included presets for fast results.
- Easy one-button operation – 8 food presets plus Warm and Dehydrate simplify routines; great for busy mornings and novice cooks.
- French door design – Ergonomic access, better heat retention when checked, and less wrist strain than top-hinged doors.
- Convection airflow – Promotes even browning across racks for crisp chicken, roasted veggies, and baked goods.

- Durability and cleanup – Stainless steel exterior resists stains; accessories are designed for easy wiping and soak-cleaning to keep maintenance simple.

How to Choose
Focus on these 4 criteria when comparing similar countertop ovens.
- Capacity vs footprint – A 24 QT cavity balances sheet-pan capability with a smaller counter footprint. Trade-offs: larger units handle roasts but take more space.
- Preset versatility – Look for clear presets like air fry, bake, and dehydrate. More presets cut guesswork but avoid overly complex menus if you want fast results.
- Accessories included – Racks, pans, and a crisping basket extend use-cases. Buying extras later adds cost and clutter.
- Cleaning and safety – Removable trays, accessible crumb areas, and cool-touch handles improve daily usability and reduce maintenance time.

Quick Setup & Use
- Unpack the oven and remove protective film from the stainless steel exterior and interior panels.
- Place the racks and chosen accessory on the lowest or middle position depending on the recipe.
- Choose a preset or set convection temperature and time using the easy one-button controls.
- Slide in food on a tray or basket and close the french doors; press start.
- Use the included recipes to test timings; adjust a few minutes for personal crispness preferences.
- After cooking, allow the interior to cool slightly, then wipe the cavity and wash accessories to keep the non-stick surfaces long-lasting.
