Step 1

For added flavor, toast the oats: Place the oats in a medium skillet, set over medium heat, and cook, stirring frequently to prevent burning, until the oats are fragrant and a shade darker, 3 to 5 minutes. Immediately transfer the oats to a medium bowl or large storage container to stop the cooking.

Step 2

Add the remaining muesli ingredients to the oats and stir to thoroughly combine.

Step 3

Cover and refrigerate for at least 6 hours and up to 1 week.

Step 4

To serve, top with fresh fruit, toasted nuts, and a drizzle of milk or maple syrup as desired.
