Can I substitute other berries in this recipe?

Absolutely! You can use any berries you enjoy or have on hand. Blueberries, raspberries, blackberries, or even chopped strawberries would work wonderfully.

How long do overnight oats last in the fridge?

I usually prep mine the night before (hence, 'overnight'!). They’re good for up to 3 days stored in the refrigerator. Just make sure they’re sealed well.

Can I use non-dairy milk?

Yup! Almond milk, soy milk, oat milk – whatever floats your boat. The key is to use something that you like the taste of, as it'll affect the overall flavor.

What can I use instead of sugar to sweeten the oats?

Sure thing. Maple syrup, honey, agave, or even a sugar-free alternative are all great. Adjust the amount to your personal sweetness preference. I find a lil’ bit of maple syrup goes a long way!

Are overnight oats good for you?

Oats are a fantastic source of fiber, which helps keep you feeling full and satisfied. The berries add antioxidants and vitamins, making this a nutritious and delicious breakfast (or snack!).

What if my oats are too thick in the morning?

If you find the oats are too thick in the morning, just stir in a little extra milk until you reach your desired consistency. Easy peasy!

⏳ Yield & Time

Yield: 1 servings

Preparation Time: 5 minutes

Cook Time: 0 minutes

Total Time: 365 minutes

🍽 Ingredients

1/2 cup Rolled Oats
1 cup Milk (dairy or non-dairy)
1 tablespoon Chia Seeds
1-2 tablespoons Sweetener (maple syrup, honey, or sugar)
1/2 cup Mixed Berries (fresh or frozen)

📖 Instructions

Grab your mason jar (or any container with a lid). This is where the magic happens!
Add the rolled oats to the jar. Make sure you use *rolled oats*, not steel-cut! Steel cut won't get soft enough overnight.
Pour in the milk (dairy or non-dairy, whatever you prefer) over the oats. Ensure the oats are mostly covered; you can always add a splash more if needed.
Stir in the chia seeds. These little guys help thicken the oats and add a nutritional boost. Don't skip 'em!
Add your sweetener of choice. Start with a tablespoon of maple syrup or honey and adjust to taste. Err on the side of less; you can always add more in the morning.
Now, for the berries! Gently fold in half of your fresh or frozen berry mix into the oat mixture. This is where the 'swirl' starts to take shape.
In a separate small bowl, mash the remaining berries with a fork. This creates a vibrant berry 'swirl' that will add both flavor and visual appeal.
Drizzle the mashed berry mixture over the top of the oat and berry mixture in the jar. Don't stir it in completely; let it create beautiful swirls and pockets of berry goodness.
Seal the jar tightly with a lid. Make sure it's secure to prevent any spills or messes in the fridge.
Place the sealed jar in the refrigerator and let it sit overnight, or for at least 6 hours. This allows the oats to soften and absorb the flavors.
In the morning, give the oats a good stir. If they're too thick, add a splash of milk to reach your desired consistency.
Take a moment to appreciate the beautiful berry swirls you created! Maybe even snap a photo for Instagram? #SummerBerryOats

📝 Notes

For a thicker consistency, use less milk or add more chia seeds.
Feel free to add a sprinkle of nuts, seeds, or coconut flakes for extra texture and flavor.
If using frozen berries, they'll thaw overnight and create a slightly more 'saucy' texture.
If you don't have chia seeds, flax seeds are a good alternative.
