Ingredients

• 1/2 cup old-fashioned rolled oats (do not use instant oats since they get mushy overnight)
• 1/2 cup milk of your choice (dairy milk, almond milk, oat milk, or coconut milk all work great)
• 1/3 cup plain Greek yogurt (use a dairy-free yogurt to keep this vegan)
• 1 tablespoon chia seeds (these help thicken the oats and add omega-3s)
• 1 tablespoon honey or maple syrup (maple syrup is a great vegan option)
• 1 teaspoon fresh lemon zest (this is where most of the lemon flavor comes from, so do not skip it)
• 1 tablespoon fresh lemon juice (bottled lemon juice works in a pinch)
• 1/2 cup fresh or frozen blackberries (frozen blackberries are a budget-friendly option)
• 1/4 teaspoon vanilla extract (adds a lovely warmth to the flavor)
• Pinch of salt (this balances out the sweetness)

Optional toppings: extra fresh blackberries, lemon zest, granola, sliced almonds, or a drizzle of honey.

How to Make blackberry lemon overnight oats Overnight Oats

1. Grab a jar or container. A mason jar works perfectly, but any container with a lid will do. You want something that holds at least 12 ounces.
2. Add the oats and chia seeds. Pour your rolled oats and chia seeds into the bottom of the jar. Give them a quick stir to combine.
3. Mix in the wet ingredients. Add the milk, Greek yogurt, honey or maple syrup, lemon juice, lemon zest, vanilla extract, and a pinch of salt. Stir everything together really well so the oats are fully coated.
4. Add the blackberries. Gently fold in the blackberries. If you are using fresh berries, a light stir works great. If you want a swirled, jammy effect, use a fork to lightly mash a few of them before stirring.
5. Seal and refrigerate. Put the lid on your jar and place it in the refrigerator. Let it sit for at least 6 to 8 hours. Overnight works best.
6. Check the texture in the morning. Give the oats a good stir when you pull them out of the fridge. If they seem too thick, just add a splash of milk and stir again until you reach your perfect consistency.
7. Add your toppings and enjoy. Top with fresh blackberries, a sprinkle of lemon zest, or a handful of granola for some crunch. Enjoy cold straight from the jar.

Pro Tips for Perfect blackberry lemon overnight oats Overnight Oats

• Use old-fashioned rolled oats. They soak up the liquid and keep a nice chewy texture. Instant oats turn into mush, and steel-cut oats stay too firm.
• Fresh lemon zest is key. The zest has the most concentrated lemon flavor. Use a fine grater or microplane to get the best results.
• Do not skip the chia seeds. They absorb liquid and help create that thick, pudding-like texture everyone loves.
• Taste before adding sweetener. Blackberries can be sweet or tart depending on the season. Taste your berries first, then decide how much honey or maple syrup to add.
• Mash some berries for a jam-like swirl. If you want a more intense blackberry flavor throughout the oats, mash a few berries before mixing them in.
• Let it sit long enough. Six hours is the minimum, but eight to ten hours gives you the best creamy texture.
• Prep multiple jars at once. This recipe is perfect for batch cooking. Make three to five jars on Sunday and grab one each morning.

Flavor Variations

Once you fall in love with this base recipe, try one of these fun twists to keep things interesting all week long.

Blackberry Lemon Cheesecake Oats: Add two tablespoons of cream cheese or dairy-free cream cheese to the mixture. It gives the oats a rich, tangy flavor that tastes just like cheesecake. Top with a few crushed graham crackers in the morning.

Blackberry Coconut Oats: Swap the regular milk for full-fat coconut milk and add a tablespoon of toasted coconut flakes. The tropical flavor pairs beautifully with the tart blackberries.

Blackberry Lemon Protein Oats: Stir in one scoop of vanilla protein powder along with the other ingredients. This boosts the protein to around 25 to 30 grams per serving, making it perfect for post-workout mornings.

Mixed Berry Lemon Oats: Use a combination of blackberries, blueberries, and raspberries instead of just blackberries. The mix of flavors is delicious and colorful.

Storage Tips

These oats store really well, which makes them perfect for meal prepping. Keep your jar tightly sealed in the refrigerator for up to five days. The oats may thicken more as the days go on, so just stir in a little extra milk each morning to loosen them up.

It is best to add crunchy toppings like granola or nuts right before eating so they do not get soggy. Fresh berries used as a topping should also be added in the morning for the best texture.

Freezing is not recommended for this recipe. The texture of the oats and yogurt changes after freezing and thawing, and it will not be as enjoyable.

Frequently Asked Questions

Can I use frozen blackberries instead of fresh?

Yes, absolutely. Frozen blackberries work great in this recipe and are often more affordable. Just add them frozen directly to the jar. They will thaw overnight in the fridge and release their juices into the oats, creating a beautiful purple swirl throughout.

Can I make this recipe vegan?

Yes, it is very easy to make this recipe vegan. Use plant-based milk like oat milk or almond milk, swap the Greek yogurt for a dairy-free coconut or almond yogurt, and use maple syrup instead of honey. The result is just as creamy and delicious.

Do I have to use chia seeds?

Chia seeds help thicken the oats and add nutrition, but you can leave them out if you prefer. Your oats will be a bit thinner without them. You could also substitute one tablespoon of ground flaxseed for a similar thickening effect.

How long do overnight oats need to soak?

The minimum soak time is about six hours. Overnight, which is usually eight to ten hours, gives you the best creamy and thick texture. If you are in a hurry, you can let them soak for a minimum of two hours, but the oats will not be as soft.

Can I eat overnight oats warm?

Yes, you can warm them up if you prefer a hot breakfast. Transfer the oats to a microwave-safe bowl and heat in 30-second intervals, stirring between each one, until they reach your desired temperature. Add a splash of milk if they seem too thick after warming. Keep in mind that the blackberries will get softer when heated.
