Overnight oats provide a simple and convenient alternative to traditional oatmeal. Instead of cooking oats, you let them soak in milk overnight. This way, they absorb the liquid and become soft and ready to eat without any additional effort.

I love having no-cook oats for breakfast, especially in warm weather. They’re cool, creamy, and nutritious. To enhance their flavor, I like to add fresh fruits and berries.

The best part is that you can prepare a large batch and enjoy it throughout the week. So, on those busy mornings, simply grab a jar and a spoon, and you’re all set!

Ingredients & substitutions

Ingredients for blueberry overnight oats, including rolled oats, blueberries, almond milk, maple syrup, and vanilla extract.

Here are some helpful notes about the key ingredients for this healthy breakfast:

  • Rolled oats: choose old-fashioned rolled oats for the creamiest results. If you have a gluten allergy or intolerance, opt for certified gluten-free oats. Instant, quick-cooking, and steel-cut oats won’t give you the same texture as rolled oats.
  • Almond milk: feel free to use any kind of dairy or non-dairy milk, or even yogurt. Just remember to maintain a 1:1 ratio with the oats.
  • Blueberries: while fresh blueberries are fantastic, frozen ones can work just as well, especially when fresh ones are out of season.
  • Sweetener: adjust the sweetness to your liking by using honey, maple syrup, or your preferred sweetener.

This recipe is a breeze and only takes about 2 minutes!

  1. Grab a mason jar and combine equal parts of milk and oats, along with maple syrup and vanilla extract.
