What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1For the best texture, use old-fashioned rolled oats. Instant oats will become mushy, and steel-cut oats will not cook through properly in this time.
- 2Avoid overmixing the batter. Stirring just until the ingredients are combined prevents the oatmeal from becoming tough or dense.
- 3For easy removal and cleanup, line the baking dish with parchment paper, leaving an overhang on two sides to use as handles.
- 4Let the baked oatmeal cool for at least 10 minutes before slicing. This allows it to firm up and hold its shape.
- 5This recipe is excellent for meal prep. Store leftovers in an airtight container in the refrigerator for up to 5 days.
- 6To reheat, microwave a slice for 30-60 seconds or warm it in a toaster oven. It's also delicious cold!
