Equipment

  • mason jar or airtight container
  • Spoon

Ingredients

  • 1/2 cup old-fashioned rolled oats
  • 1/2 cup milk (dairy or non-dairy)
  • 1 tbsp chia seeds (optional)
  • 1-2 tsp maple syrup or honey (optional)

Instructions

  • Add rolled oats to a mason jar or airtight container.
  • Pour in milk and stir well to combine.
  • Stir in chia seeds and sweetener if using.
  • Seal the jar and refrigerate for at least 4 hours or overnight.
  • Stir before serving. Add fresh fruit, nut butter, or protein add-ins as desired.

Notes

Use old-fashioned rolled oats for best texture. Refrigerate at least 4 hours, ideally overnight. If too thick, stir in 1–2 tablespoons milk before serving. If too thin, add 1 teaspoon chia seeds and chill 30 minutes. Add fresh fruit just before serving for best texture. Store up to 5 days in an airtight jar.
