Ingredients You’ll Need
- Gluten-Free Rolled Oats (also called old-fashioned oats): The base of this recipe, oats provide a hearty texture and fiber. I recommend Bob’s Red Mill for its certified gluten-free oats to ensure they’re safe for anyone avoiding gluten.
- Blueberries: Fresh juicy blueberries or frozen work great here! Use what you have on hand.
- Chia Seeds: These add fiber and help create a creamy, pudding-like texture.
- Maple Syrup: A natural sweetener that balances the tartness of the blueberries.
- Vanilla Extract & Cinnamon: For warmth and a hint of sweetness.
- Salt: A small pinch enhances all the flavors.
- Dairy-Free Milk: The liquid base for soaking the oats. Cashew, almond, or coconut milk works perfectly and adds creaminess without dairy. If you’re not dairy-free, feel free to use regular milk instead of non-dairy milk.
- Vanilla Protein Powder (optional): Ideal if you want to make these oats more filling. It adds a protein boost and enhances the vanilla flavor, making this a great post-workout or high-protein breakfast option.

Use extra blueberries to make blueberry banana muffins, blueberry turnovers, or blueberry baked oatmeal.
Recipe Variations
- Swap the Fruit: Try strawberries, raspberries, or ripe bananas instead of blueberries.
- Change the Milk: coconut, cashew, almond milk—You can really use any kind of milk that you like.
- Mix-Ins: Add nuts, lemon zest, hemp seeds or flax seeds, or shredded coconut is a great way to add extra texture and nutrition. Drizzle peanut butter or almond butter on top for some extra healthy fats.
- Warm It Up: If you prefer warm oats, heat a serving in the microwave for 30-60 seconds before eating.
How to Make Blueberry Overnight Oats
Step 1: Combine Ingredients. In a large bowl, stir together the oats, blueberries, chia seeds, maple syrup, vanilla extract, cinnamon, and salt. Add the dairy-free milk and a scoop of protein powder (if using).
Step 2: Mix until well combined.
Step 3: Refrigerate. Cover the mixture with plastic wrap or divide it into 4-5 individual glass jars or containers. Seal tightly and place in the fridge for at least 12 hours or overnight.
Step 4: Serve. The next morning, give the oats a good stir before serving. Enjoy straight from the jar or bowl, and feel free to add your favorite toppings.
Expert Tips
- Use Fresh or Frozen Blueberries: Frozen blueberries will thaw overnight, releasing their juices and adding natural sweetness.
- Adjust the Sweetness: Maple syrup adds just the right touch, but you can increase or decrease it based on your taste.
- Meal Prep Like a Pro: Use glass mason jars or small containers with lids to portion out servings. This makes breakfast super convenient all week long.
- Protein Power: Adding vanilla protein powder not only ups the protein but also makes the oats extra creamy.
Serving Tips
Toppings: Extra blueberries (fresh), a drizzle of almond butter, or a sprinkle of granola take these oats to the next level.
Make It a Complete Breakfast: Pair with a cup of coffee, some scramble eggs, or green smoothie for a balanced morning meal.
Quick Snack: These work just as well as a grab-and-go snack for busy afternoons or as a pre or post-workout snack.
Hassle-Free Breakfast: Try using this as a smoothie base for a quick blend-and-go breakfast or layering them with dairy free yogurt or vanilla Greek yogurt and granola for a delicious parfait in just a few minutes of prep.
Storage Tips
Keep your overnight oats fresh by storing them in an airtight container in the fridge for up to 5 days. The longer they sit, the creamier they get, making them perfect for meal prep!
If you’re adding fresh fruit, nuts, or granola, wait to add those right before eating to keep everything fresh and crunchy.
Overnight oats don’t freeze well due to the change in texture when thawed. Stick to refrigerating for the best results.
Recipe FAQs
These oats are a powerhouse of nutrition. They’re loaded with fiber from the oats and chia seeds, helping to keep you full and satisfied longer. The chia seeds and dairy-free milk also provide healthy fats, which are essential for sustained energy. Plus, blueberries are a superfood bursting with antioxidants, vitamins, and minerals, making this a breakfast that’s as nourishing as it is delicious.
Yes, oats themselves are naturally gluten-free, but they’re often processed in facilities that handle wheat, barley, or rye, leading to cross-contamination. To ensure they’re safe for a gluten-free diet, look for oats labeled as “certified gluten-free,” like those from Bob’s Red Mill or other trusted brands.
Yes! If you don’t need gluten-free oats, regular rolled oats from any brand will work perfectly. You can also use steel-cut oats but the texture will vary. Steel-cut oats are firmer and chewier, so if you prefer using them, you may need to increase the soaking time to at least 24 hours or partially cook them before mixing to achieve a softer texture.
You can skip them, but the oats will be slightly less creamy. Ground flaxseed is a great substitute.
Yes, you can leave out the sweetener altogether if you prefer. The blueberries will offer some natural sweetness to the oats.
