Ingredients you’ll need

Old-fashioned rolled oats give the best creamy-yet-chewy texture; avoid instant oats, which get mushy.

• 1/2 cup milk of choice
• 1/4 cup Greek yogurt
• 1 tablespoon chia seeds
• 1 teaspoon maple syrup or honey
• 1/2 teaspoon vanilla extract
• Pinch of salt
• Toppings: fruit, nut butter, granola

How to make overnight oats (step by step)

1. Add the oats, milk, Greek yogurt, chia seeds, sweetener, vanilla, and salt to a jar or container.
2. Stir well until everything is combined and the chia seeds are evenly distributed.
3. Seal and refrigerate for at least 4 hours, or overnight.
4. In the morning, stir and add a splash more milk if you like it looser.
5. Top with fruit, nut butter, or granola and enjoy cold, or warm it briefly if you prefer.

Tips for the best results

• Use rolled oats, not instant, so they hold their texture.
• Chia seeds thicken the oats and add fiber and omega-3s.
• Make several jars at once for the whole week.

Variations & substitutions

• Peanut butter banana: add a spoonful of peanut butter and sliced banana.
• Berry: stir in mixed berries and a little extra maple.
• Chocolate: add a teaspoon of cocoa powder and a few chocolate chips.

Storage & make-ahead

Overnight oats keep in the fridge for up to 5 days, making them perfect for weekly meal prep. Add fresh fruit just before eating.
