These creamy blueberry overnight oats are perfect in the height of the summer when blueberry season is at it’s peak or any time of year you need a berry fix– just use frozen blueberries! (In my opinion–frozen blueberries are actually superior for this recipe–but tossing fresh berries on top is *chef's kiss).

Make these in rotation with my apple pie overnight oats, banana bread overnight oatmeal, or cinnamon roll overnight oats. All you need is a few minutes in the evening,some sweet juicy blueberries, and a couple of additions to my basic overnight oats recipe to make my favorite healthy breakfast!

Why You’ll Love This Recipe

• You only need 7 ingredients and 5 minutes to whip up one or many servings of this recipe, which makes it perfect for tossing together before bed. 
• Use fresh-picked blueberries or frozen berries to enjoy any time of year. 
• Easily double or triple this recipe for breakfast every day of the week!
• It’s packed with whole grains, and one serving has 22 grams of protein and 7 grams of fiber for a satisfying and filling breakfast. 

🛒 Key Ingredients

• Rolled oats: The base of the recipe, whole grain oats, gives this breakfast a hearty texture and adds plenty of heart-healthy soluble fiber. 
• Milk: Adds creaminess and helps the oats soften overnight. You can use dairy or plant-based milk, depending on diet preference and needs. 
• Plain Greek yogurt: Adds plenty of protein and a creamy texture. You can also use a low-sugar vanilla yogurt, which tastes amazing! 
• Blueberries: You can’t have blueberry oatmeal without the blueberries! Use either fresh or frozen (no need to thaw!) and save a few extras for tossing on top just before eating! 
• Chia seeds: Help thicken the oat mixture and add a boost of fiber and omega-3 fatty acids. 
• Maple syrup: A natural sweetener that adds the perfect touch of sweetness and really subtle maple flavor. 
• Vanilla extract: Ties everything together with a subtle hint of sweet vanilla flavor (you can skip if using vanilla flavored yogurt!).

See recipe card for quantities.

🥣 Step by Step Instructions

1. Combine all of the ingredients into a mixing bowl or mason jar. 
2. Shake or stir until well combined, then cover and refrigerate for at least 4 hours. 
3. The next morning, stir the oat mixture and eat as is or top with a handful of blueberries, a drizzle of maple syrup and a sprinkle of walnuts if desired! 

🗯 Tips and Tricks

• The texture is best if you let the oat mixture soak overnight, you can eat them after four hours in the refrigerator– that should be enough time for the oats to soften. If they seem a little thick, just add a splash of milk and stir it all together again. 
• Prep in batches. On the recipe card, use the multiplier to make 2 or 3 batches at once! You can mix everything in a large bowl and portion it out into mason jars or individual containers, or just store in one large container and scoop what you need throughout the week.
• While instant oats or steel cut oats CAN work… rolled oats (old-fashioned oats) are the best choice for this recipe. If using quick oats, you may need less milk. Steel-cut oats will need more liquid and longer soaking time, and the texture will be more chewy. 

↔️ Customize it

Use these substitutions and variations to make this easy blueberry overnight oats recipe your own! 

• Make it high protein: While this recipe has 22 grams of protein you can add extra protein by adding protein powder or a protein shake instead of milk. Add half a scoop of protein powder and whisk it into the milk before adding to the oatmeal or swap the milk with a protein shake like Core Power High Protein or Orgain Protein. 
• Make it plant-based: While this recipe uses regular dairy milk, you can make it vegan and dairy-free by using dairy-free milk like oat milk, almond milk, coconut milk, or soy milk. Swap the Greek yogurt with a plant-based creamy yogurt. 
• Make it lemon blueberry: Make it this blueberry lemon overnight oatmeal by adding a teaspoon of grated lemon zest and a quick squeeze of juice to the oat mixture. 
• Use your favorite toppings: Top with additional blueberries, mixed berries like raspberries or blackberries, granola or add a boost of healthy fats with a sprinkle of walnuts, pecans, seeds, almond butter, peanut butter, cashew butter, hemp hearts, pumpkin seeds, or flax seeds. 
• Use a different sweetener: Maple syrup adds wonderful flavor and sweetness, but you can use any sweetener you’d like. Use monk fruit, allulose, or stevia for a no added sugar version or swap the maple syrup for brown sugar, honey, or table sugar.
