# Expert Suggestions:

01 -
  • It's a make-ahead breakfast that feels like you're treating yourself while actually supporting your body with whole grains and protein.
  • The Greek yogurt swirl creates this creamy contrast against the tender oats that somehow feels both comforting and light.
  • Frozen blueberries release their juice as they bake, turning the whole thing into a naturally sweet masterpiece without refined sugar.
02 -
  • Frozen blueberries are actually your friend here—they release more juice as they bake than thawed ones, creating those pockets of flavor throughout.
  • Don't skip the cooling time or you'll end up with a crumbly mess instead of neat slices, and the flavors meld better once it's cooled slightly anyway.
03 -
  • Use a sharp knife dipped in hot water and wiped dry between slices to cut clean portions without dragging the soft bake around.
  • The yogurt swirl is more about visual appeal than flavor—if you prefer, you can stir it directly into the batter for a more uniform texture instead.
