Ingredients
Scale
- 1 cup (90g) rolled oats (old-fashioned oats)
- 1 cup (240ml) milk (any kind)
- ½ cup (120g) plain Greek yogurt
- 2 tablespoons (30ml) honey or maple syrup
- 1 tablespoon (12g) chia seeds (optional)
- 1 teaspoon (5ml) vanilla extract
- ⅛ teaspoon salt
- Fresh fruit for topping (e.g., berries, sliced bananas, diced apples)
- Optional mix-ins: peanut butter, cinnamon, shredded coconut, dark chocolate chips
Instructions
- In each mason jar, add ⅓ cup (30g) of rolled oats and 1 teaspoon of chia seeds (if using). Shake to distribute.
- In a small bowl or liquid measuring cup, whisk together ⅓ cup (80ml) of milk, 2 heaping tablespoons (about 30g) of Greek yogurt, 2 teaspoons (10ml) of honey or maple syrup, ¼ teaspoon of vanilla extract, and a tiny pinch of salt until smooth.
- Pour the wet mixture over the oats in the jar. Stir well, making sure all oats are submerged. Scrape down the sides.
- Screw the lid on tightly and refrigerate for at least 6 hours, preferably 8-12 hours.
- In the morning, stir the oats. If too thick, add a splash of milk. Add toppings like fresh berries, sliced banana, a drizzle of honey, or granola. Eat cold or let sit at room temperature for 10 minutes.
- Optional: Microwave (without metal lid) for 30-45 seconds if you prefer warm oats. Transfer to a microwave-safe bowl first if needed.
Notes
The ratio is key: 1 part oats to about 1.3 parts liquid (including yogurt). Don’t skip the salt—it enhances sweetness. Let oats rest at least 6 hours for best texture. Batch prep 4-5 jars on Sunday for the week. Flavors develop over time; day 2 is often better. Freezing not recommended.
