A creamy, nutritious overnight oats recipe with chia seeds and fresh or frozen berries, perfect for busy mornings and meal-prep.

Ingredients

Scale
  • 1 cup (90g) old-fashioned rolled oats
  • 2 tablespoons (20g) chia seeds
  • 1 ½ cups (360ml) milk of choice (unsweetened almond milk, oat milk, or dairy milk)
  • ½ cup (120g) plain Greek yogurt, unsweetened
  • 12 tablespoons (15-30ml) honey or maple syrup
  • 1 teaspoon (5ml) vanilla extract
  • ½ teaspoon (1.3g) cinnamon
  • 1 cup (150g) fresh or frozen mixed berries (blueberries, raspberries, strawberries, blackberries)
  • Optional toppings: sliced almonds, shredded coconut, or a dollop of nut butter

Instructions

  1. Combine 1 cup rolled oats and 2 tablespoons chia seeds in a mixing bowl or jar and stir to mix evenly.
  2. Add 1 ½ cups milk, ½ cup Greek yogurt, 1-2 tablespoons honey or maple syrup, 1 teaspoon vanilla extract, and ½ teaspoon cinnamon. Stir vigorously until smooth and creamy with no clumps.
  3. Check consistency; if too thick, add a splash more milk; if too thin, add more oats or yogurt.
  4. Spoon mixture into individual 16 oz (475ml) jars or containers, leaving room at the top.
  5. Top each jar with about ½ cup (75g) fresh or frozen mixed berries.
  6. Seal jars with lids and refrigerate for at least 6 hours or overnight.
  7. Serve cold or at room temperature; optionally warm in microwave for 30 seconds. Add optional toppings before serving.

Notes

Use old-fashioned rolled oats for best texture; quick oats get mushy. Stir well to prevent chia seed clumps. Adjust sweetness to taste. Frozen berries thaw overnight and add natural juice for marbled effect. Prep 3-5 jars ahead for the week. Do not freeze fully prepared jars to maintain texture.
