Decision guide
How to decide
Proofing, slow cooking and dehydration point to the BOV900. When two-level family meals are why you want a countertop oven at all, the Ninja DT501 is attractive.
Start from what you cook repeatedly
Neither is a small oven. Breville spreads a wide recipe range across thirteen modes, and Ninja puts its weight on food on two levels inside the Smart Surround Convection cavity.
Tie the modes to your menu
Prefer Breville if proofing or slow cooking is a routine of yours. Tallying up functions without thinking about your food can hide the fact that plenty of meals need only Bake or Roast.
Even with two racks, there is one cavity
Different foods do not get independently controlled chambers in either oven. When two trays cook together, they share one oven temperature and have to follow the rack guidance.
What this page can’t tell you
- For this comparison, equipment and capacity rely on manufacturer specifications, and cooking or preparation outcomes have had no independent testing.
