Healthy Blueberry Overnight Oats

Make Blueberry Overnight Oats in just 2 minutes for a healthy and delicious breakfast!

This quick and easy recipe is packed with nutrients and flavor, and it’s the perfect way to start your day feeling energized and satisfied!

Overnight oats offer a simple and convenient alternative to traditional oatmeal. Instead of cooking oats on the stove or in the microwave, you just soak them in milk overnight. By doing so, the oats absorb the liquid and become soft and ready to eat without any extra effort.

Thanks to their no-cook nature, overnight oats have become my preferred breakfast option, especially during warmer weather. They are refreshingly cool, creamy, satisfying, and packed with nutrients. To enhance the flavor, I love adding fresh, seasonal fruits and berries.

What’s even better is that you can prepare a large batch and enjoy it throughout the week. On busy mornings, simply grab a jar and a spoon, and you are good to go!

Ingredients & substitutions

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

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

How to make healthy overnight oats

This recipe is quick and easy, taking just 2 minutes to put together!

1. Grab a mason jar and combine equal parts of milk and oats, along with maple syrup and vanilla extract.
2. Next, add the blueberries, seal the jar tightly, and give it a good shake.
3. Let it rest in the refrigerator overnight for a minimum of 4 or 5 hours.
4. Then, in the morning, add a splash of milk if you prefer a thinner texture and gently stir.
5. Top your oats with fresh blueberries, a drizzle of maple syrup, and some hemp seeds and flaxseed meal.

Note: overnight oats are typically enjoyed cold, but if you prefer them heated, remove the lid and microwave them for about 1 minute.

Recipe variations

Get creative with your own combinations, or mix and match these variations to suit your taste buds and dietary needs.

• Chocolate twist: sprinkle some cocoa powder or a few dark chocolate chips onto your oats.
• Tropical paradise: add sliced bananas and shredded coconut. You could also top your oats with mango, pineapple, or papaya for a truly tropical taste.
• Autumn-inspired: incorporate diced apples, a sprinkle of cinnamon, and a touch of nutmeg.
• Fresh and dried fruit: try raspberries, strawberries, peaches, pears, apples, raisins, cranberries, goji berries, or chopped dates.
• Crunchy nuts and seeds: add sliced almonds, chopped pecans or walnuts, hemp seeds, sunflower seeds, or toasted sesame seeds. You could also add a spoonful of chia seeds or ground flaxseed for extra fiber and omega-3s.
• Spice it up: stir in cinnamon, nutmeg, turmeric, cardamom, or ginger.
• Protein-packed: boost your protein intake with a dollop of Greek yogurt, cottage cheese, or protein powder.
• Sweetness drizzle: add a swirl of honey or maple syrup for a touch of sweetness. You could also add a spoonful of your favorite jam or preserves.
• Gluten-free option: use certified gluten-free oats.
• Vegan alternative: opt for maple syrup or agave nectar as a sweetener.
• Make it sugar-free: skip the sweetener and instead add half a mashed, ripe banana.

Make-ahead & storage tips

Storage: overnight oats will keep well in the fridge for up to 5 days. However, if you’ve added fresh fruit toppings or mix-ins, it’s best to consume them within 3 days to ensure optimal freshness. Before serving, give the oats a good stir.

To freeze overnight oats, omit fresh blueberries, store individual portions in airtight containers, and freeze. Thaw overnight in the refrigerator and add fresh blueberries before serving.

To meal prep, prepare a larger batch, divide into individual portions, and store in airtight containers or mason jars. Grab and enjoy a quick and convenient breakfast throughout the week.
