Ingredients

Scale
  • 1 cup old-fashioned rolled oats (90 g)
  • 1 cup milk of choice (240 ml) – dairy or plant-based (almond, oat, or coconut milk)
  • ½ cup Greek yogurt (120 g), plain or vanilla (can substitute with dairy-free coconut yogurt)
  • 1 tablespoon fresh lemon zest (from about one medium lemon)
  • 2 tablespoons fresh lemon juice (freshly squeezed)
  • ½ cup fresh or frozen blueberries (75 g)
  • 12 tablespoons honey or maple syrup (adjust sweetness to taste)
  • 1 tablespoon chia seeds (optional)
  • ½ teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Combine 1 cup old-fashioned rolled oats with 1 tablespoon chia seeds (if using) in a large bowl or mason jar.
  2. Add 1 cup milk of choice and ½ cup Greek yogurt. Stir gently to combine, breaking up any clumps of yogurt.
  3. Add 1 tablespoon fresh lemon zest, 2 tablespoons fresh lemon juice, 1-2 tablespoons honey or maple syrup, ½ teaspoon vanilla extract, and a pinch of salt. Mix well to distribute flavors evenly.
  4. Gently fold in ½ cup fresh or frozen blueberries.
  5. Cover the jar or bowl and refrigerate for at least 6 hours, preferably overnight.
  6. Before serving, stir the oats. If too thick, add a splash of milk to loosen. Adjust sweetness or lemon flavor if needed.
  7. Optional: Add extra blueberries or a sprinkle of sliced almonds for crunch. For a warm version, microwave for 20 seconds.

Notes

Use old-fashioned rolled oats for best texture; quick oats can become mushy. Fresh lemon juice is essential for brightness. Chia seeds help thicken the oats overnight. Adjust sweetness after soaking if needed. For creamier texture, add cottage cheese or protein powder before mixing oats. Store in airtight containers for up to 4 days. Warm briefly in microwave if preferred.
