Ingredients You’ll Need
- Gluten-Free Rolled Oats: These provide the hearty base and fiber. Look for certified gluten-free oats like Bob’s Red Mill.
- Blueberries: Fresh or frozen both work. Frozen blueberries thaw overnight and make the oats extra sweet.
- Chia Seeds: Help thicken the oats and add fiber and healthy fats.
- Maple Syrup: Adds natural sweetness. Adjust to taste.
- Vanilla Extract + Cinnamon: Adds warmth and depth.
- Salt: Just a pinch to balance the sweetness.
- Non-Dairy Milk: Almond, oat, or coconut milk all work beautifully. If you’re not dairy-free, regular milk is fine too.
- Vanilla Protein Powder (optional): Adds extra protein and makes the oats extra creamy.
Use extra blueberries to make blueberry banana muffins, blueberry turnovers, or blueberry baked oatmeal.
How to Make Blueberry Overnight Oats
Step 1: Mix Ingredients. In a large bowl, stir together oats, blueberries, chia seeds, maple syrup, vanilla, cinnamon, and salt. Add in your choice of milk and a scoop of protein powder if using.
Step 2: Mix until well combined.
Step 3: Refrigerate. Cover with plastic wrap or divide into large mason jars or small airtight containers. Refrigerate for at least 12 hours or overnight.
Step 4: Serve. Give the oats a good stir the next morning. Enjoy them cold, or warm gently in the microwave. Top with your favorite mix-ins or more sweet blueberries.
Expert Tips
- Frozen Blueberries: No need to thaw! They soften overnight and release juices for added flavor.
- Adjust Sweetness: Start with less maple syrup and add more if needed.
- Meal Prep Like a Pro: Portion into airtight mason jars so you can grab and go all week.
- Boost Protein: Stir in vanilla protein powder or top with nut butter for more staying power.
Serving Ideas & Variations
- Toppings: Try peanut butter, almond butter, chopped nuts, or a sprinkle of granola.
- Fruit Swaps: Sub blueberries for strawberries, raspberries, or diced banana.
- Milk Options: Use oat milk, soy milk, or coconut milk depending on preference.
- Add-Ins: Try lemon zest, shredded coconut, or flaxseed for added nutrition.
- Warm It Up: Microwave 30–60 seconds if you prefer warm oats.
- Make It a Complete Breakfast: Pair with a cup of coffee, some scrambled eggs, or green smoothie for a balanced morning meal.
Storage Tips
- Refrigerate: Store in an airtight container in the fridge for up to 5 days. The oats get creamier the longer they sit!
- Keep Toppings Separate: Add granola or fresh fruit right before eating to maintain crunch and freshness.
- Freezing Not Recommended: Freezing changes the texture—refrigeration works best.

Delicious! I forgot to spray the bottom so the bottom of it got a bit stuck, but the taste was still there. I opted to melt the butter in a pan before pouring it in and I wonder if it makes a difference whether or not I pour the butter in while hot or a little cooled down. All in all, would make again!
