Here's how to make blueberry overnight oats in 3 simple steps:
Step 1: In a small bowl, stir together all ingredients except the blueberries.
Step 2: Stir in the blueberries.
Step 3: Store in an airtight container (like a jar) for at least 4 hours, preferably overnight. If preferred, add a splash more milk to thin your oats after they sit overnight for a thinner consistency.
Here's more information on the ingredients for this recipe:
- Oats: You'll want to use rolled oats for this recipe since they are thicker than instant or quick cook oats and soften better overnight than steel cut oats. I use these 'Old Fashioned' Rolled Oats.
- Almond Milk: This recipe uses almond milk but you can substitute your preferred milk alternative (like oat, soy, or coconut milk) or regular milk.
- Chia Seeds: You can use any type of chia seeds.
- Maple Syrup: use pure maple syrup or swap this out for your preferred sweetener (like honey or agave syrup).
- Blueberries: Frozen wild blueberries work best in this recipe and will turn the oats a dark blue/purple color. Frozen regular blueberries or fresh blueberries will also work but they will add less flavor to the oats.
Here are a few popular substitutions and additions to this recipe:
- Vanilla: add 1 teaspoon of vanilla to highlight all the flavors in the recipe.
- Nuts: add 2 tablespoons nuts to your oats (walnuts, pecans, almonds, etc) for crunch.
- Peanut butter: add 1 tablespoon of peanut butter (or almond butter) to your oats for some hearty, nutty flavor.
- Cinnamon: a sprinkle of cinnamon is always tasty in overnight oats.
- Hemp seeds: top your overnight oats with a sprinkle of hemp seeds for added nutrients.
- Kefir: kefir is a fermented milk drink that's rich in gut-healthy probiotics. Try adding some to your overnight oats instead of using almond milk.
Small jars are nice to have for this recipe; but if you don't have jars, you can use any airtight container.
Jars work best for this recipe because they fit a serving of oats and you can take it on-the-go in the morning for a convenient breakfast.
Store your blueberry overnight oats in an airtight container in the fridge. Properly stored, this recipe will stay good for about 5 days in the fridge.
I like to meal prep this recipe by making a big batch (4 servings) and storing it in these mason jars so that I have a serving ready for each morning. This recipe works great as a grab-and-go breakfast or healthy snack.
- Make it as meal prep: This recipe is for 1 serving of oats. You can easily 4x or 5x the recipe and make this recipe as meal prep for the week.
- Add toppings: get creative with toppings on your oats to add flavor. For example, you can add a drizzle of syrup, flax or hemp seeds, fresh blueberries, or nuts.
- Eat it warm or cold: Overnight oats are typically eaten cold, but you can also warm them up on the stovetop or in the microwave if you're craving a hot breakfast (I love to do this in the colder months)!
- Adjust the thickness: Add a splash (or two) more milk if you prefer a thinner consistency to your oats.
Frequently Asked Questions
You'll want to use rolled oats for this recipe. You can use quick cook oats in a pinch, but the texture of your oats will be mushy. Steel cut oats are also not recommended since they won't be soft enough overnight. My favorite oats to use are 'Old Fashioned' Rolled Oats.
