Key Ingredients

  • Rolled oats. Be sure to get old-fashioned rolled oats, not quick oats or steel-cut oats, since rolled oats provide the best texture. For gluten-free preparation, make sure you purchase certified gluten-free oats, like these from Anthony’s.
  • Chia seeds. In addition to providing healthy fats, fiber, and minerals, chia also brings a pudding-like texture that really elevates these oats.
  • Milk. Dealer’s choice here. Dairy milk works well, as does almond milk, oat milk, and coconut milk. Each plant-based milk option brings a slightly different flavor so feel free to play around to find what you like best.
  •  Maple syrup. A dash of maple sweetness makes this jar of goodness so easy to eat. Out of syrup? Honey or agave nectar will work too.
  • Greek yogurt. This is truly the hidden star of this recipe. Greek yogurt brings a refreshing tang to overnight oats and provides a ton of energizing protein for your morning. If going for vegan, be sure to use plant-based Greek yogurt.

Step-by-Step Instructions

1. Mix all ingredients except blueberries in a glass container. A mason jar or glass tupperware works well for this.

2. Cover the container and place it in the fridge. Chill for a minimum of 3 hours, but 8 hours is optimal.

3. Add blueberries and top with nuts. Enjoy!

Recipe Tips, Variations, and Substitutions

  • Get the timing right. For the perfect creamy-but-not-mushy texture, aim to let your overnight oats chill for around 8 hours. Less and the oatmeal will be chewier with more liquid; more and it will be mushy.
  • Try it with other berries. Blueberries are delicious and loaded with antioxidants, but they aren’t the only berries that work with this recipe. Try it with strawberries, raspberries, or bananas (which, yes, technically are a berry!).
  • Up the protein. One addition I love to make to this recipe is to add peanut butter, almond butter, or other nut butters. This adds an extra boost of protein and makes for a more filling breakfast.
  • Add some spices. I like my oatmeal with just a touch of vanilla, but you can easily mix it up by adding cinnamon or clove.
  • Out of chia? In a pinch, you can use flax seeds in place of chia. Whole flax doesn’t quite have the same texture, but adding a teaspoon of ground flax can help recreate that gelatinous character the chia provides.
  • Go nuts. Walnuts always pair well with oatmeal but feel free to use chopped almonds, pecans, or whatever you have on hand. Or skip the nuts altogether.

Make Ahead/Storage Recommendations

While the best texture can be found around the 8-hour mark, these easy overnight oats will stay good (and plenty delicious) for up to five days in the fridge, making them meal prep friendly.

That means you can make your full week of breakfasts on Sunday evening and not have to worry about a thing.

When I make my oats a few days ahead, I like to use a little less milk during the prep process. Then, once I’m ready to eat, I add a little extra milk to get just the right texture.
