A simple, fresh, and fast no-cooler overnight oats recipe that soaks perfectly at room temperature, ideal for busy mornings without refrigeration.

Ingredients

Scale
  • 1/2 cup (45g) rolled oats (old-fashioned)
  • 1/2 cup (120ml) milk of choice (dairy, almond, oat, or soy milk)
  • 2 tablespoons (30g) Greek yogurt (optional)
  • 1 tablespoon (15ml) honey or maple syrup
  • 1 teaspoon (5g) chia seeds
  • 1/2 teaspoon (2.5ml) vanilla extract
  • 1/4 cup (40g) fresh fruit (berries, diced apples, or banana slices)
  • 1 tablespoon (10g) nuts or seeds (optional, e.g., slivered almonds or chopped walnuts)

Instructions

  1. Add 1/2 cup (45g) of rolled oats to your mason jar.
  2. Sprinkle 1 teaspoon (5g) of chia seeds over the oats.
  3. In a small bowl or directly in the jar, pour 1/2 cup (120ml) of your chosen milk, 2 tablespoons (30g) of Greek yogurt if using, 1 tablespoon (15ml) honey or maple syrup, and 1/2 teaspoon (2.5ml) vanilla extract. Stir well to combine.
  4. Pour the wet mix over the oats and chia seeds in the jar. Stir thoroughly to ensure even distribution.
  5. Top the mixture with 1/4 cup (40g) of fresh fruit and sprinkle 1 tablespoon (10g) of nuts or seeds if desired.
  6. Seal the jar tightly and leave it at room temperature for 6-8 hours.
  7. After soaking, stir the oats to mix the fruit through or eat as is. Add extra milk or yogurt before serving if desired.

Notes

Use old-fashioned rolled oats for best texture. Adjust soak time based on room temperature (6 hours if warm, 8 hours if cooler). Mix well before sealing to avoid clumps. Customize sweetness to taste. For vegan version, substitute Greek yogurt with coconut or almond yogurt and use maple syrup or agave instead of honey. Consume within 8-10 hours if kept at room temperature. Refrigerate leftovers up to 24 hours and add milk before eating if thickened.
