Tom's Guide's best overall and Serious Eats' best multi-fuel oven under $500: real wood or charcoal flavor, a door that holds heat, and a premium build. With solid fuel you have to tend the fire, temperatures swing, and the gas burner costs extra.

Top complaints

  • Temperature swings with wood or charcoal

    Tom's Guide had to top up fuel constantly and got a couple of oddly risen pies and some burnt crusts. Heat varied between pizzas and even during a single bake.

  • Gas burner and accessories cost extra

    Tom's Guide calls it pricey, especially once you add a peel, turning peel, thermometer and the roughly $112 gas burner. Ooni's own page is inconsistent on whether the burner is included.

  • Gap at the back, ambient-only gauge

    Serious Eats warns of a roughly 6-inch gap at the back of the oven that you can push a pizza into while turning. Tom's Guide notes the built-in gauge reads only air temperature, not the stone.

What owners love

  • Very crispy, restaurant-style pies

    Tom's Guide says it makes pies worthy of a pizzeria. Serious Eats cooked a pizza in about 1 minute 30 seconds.

  • Fast heat-up with a heat-holding door

    On charcoal and wood, the stone hit 750°F in 10-12 minutes in Tom's Guide's test. Serious Eats says its door locks in heat for back-to-back pies.

  • Premium, foldable build

    Tom's Guide found it built to last, with folding legs and a removable chimney; at about 33 lb it is one of the lightest ovens Serious Eats recommends.

Good for
  • Wood- or charcoal-fired flavor
  • Switching between wood, charcoal and (with an add-on) gas
  • Small groups of about 4-6

Scores (tap for why)

  • Pizza results4.0
    Why 4.0?Excellent, very crispy pies (Tom's Guide; Serious Eats), but solid fuel gave some unevenly risen or burnt crusts.
  • Heat-up & recovery4.0
    Why 4.0?750°F in 10-12 minutes on wood and charcoal (Tom's Guide); the door helps recovery (Serious Eats). Heat drops as fuel burns down.
  • Ease of use (turning, learning curve)3.0
    Why 3.0?Simple controls, but you must tend fuel and watch temperature (Tom's Guide), and the rear gap catches pies (Serious Eats).
  • Size & portability4.0
    Why 4.0?33.6 lb with folding legs and a removable chimney; Tom's Guide found it relatively easy to carry, though a Gozney Tread is more portable.
  • Build & durability4.0
    Why 4.0?Premium construction that feels built to last (Tom's Guide); 5-year warranty on ooni.com purchases. Tom's Guide says the stone can crack if the oven is left out in the elements.

What experts say

  • Tom's Guide: Best overall (updated Aug 2026): flexible fuels, quick assembly and fast heat; not sized for large parties, and temperature needs active attention.
  • Serious Eats: Best multi-fuel oven under $500, lighter and fast to heat; watch the gap at the back when turning.
