Why you’ll love it
Meal prep – If you like to meal prep your breakfast or snacks for the week, overnight oats are a great option. They’ll keep in the fridge for up to 4 days.
Healthy breakfast or snack – Oats are a great source of fiber, protein, antioxidants, and contain a variety of vitamins and minerals. They also have a low GI score, meaning they’re less likely to cause blood sugar spikes and crashes.
High protein – Oatmeal isn’t usually categorized as a high protein breakfast or snack, but thanks to Greek yogurt, protein powder, and the protein naturally found in oats, there’s 27 grams of protein per serving.
- Greek yogurt – Plain Greek yogurt adds creaminess and protein.
- Milk – I like to use unsweetened vanilla almond milk, but any type of milk, dairy or non-dairy can be used.
- Vanilla protein powder – Protein powder is a great way to boost the protein in overnight oats. If you use a sweetened protein powder you won’t need to add additional sweetener.
- Vanilla extract – Vanilla enhances the lemon flavor.
- Lemon zest – The zest adds the perfect amount of lemon flavor without the tartness that the juice would give off.
- Rolled oats – Also called old fashioned oats. Don’t use quick oats for this recipe.
- Chia seeds – Another good source of protein. They also thicken the overnight oats.
- Salt – A pinch of salt balances the sweet flavors and enhances the flavor of the oats.
How to make blueberry lemon overnight oats
In a bowl whisk together the milk, yogurt, vanilla, and lemon zest.
Once it’s combined add in the chia seeds, protein powder, and a pinch of salt. Stir in the oats and taste to see if it’s sweet enough for your liking.
Cover the bowl with plastic or a lid and refrigerate it overnight or divide the oats into 2 jars. I like to use 8 ounce mason jars.
Once the oats have been refrigerated for at least 3 hours or overnight they’re ready to eat. Top them with blueberries or layer them in like I’ve done in the photos.
Once you’ve made the overnight oat mixture, store it in a covered bowl or jars with lids in the refrigerator. The oats will keep for up to 4 days.
If you’re unsure if they’re still safe to eat, just smell them. They shouldn’t smell sour.
Overnight oats FAQs
Can frozen blueberries be used for overnight oats?
Yes. Let the blueberries defrost and then add them into the overnights when you’re ready to eat them. If meal prepping you can add them into individual jars, but be aware that the oats will be discolored.
Can overnight oats be eaten warm?
Yes. You can heat them in the microwave for 30 second intervals until warm. You may need to add a little milk depending on how thick or thin you like your oatmeal.
Can quick oats be used to make overnight oats?
Yes, but personally I don’t like the consistency. It will be more mushy, similar in consistency to that of porridge.
What can protein powder be replaced with?
If you don’t want to use protein powder, omit it and replace with 2 tablespoons or to taste of honey or maple syrup.
Can I make the overnight oats without chia seeds?
Yes. If you don’t like the texture of chia seeds, omit them and replace with an additional tablespoon of oats.
What is the consistency of overnight oats?
I prefer my overnight oats to be super thick and creamy, almost the consistency of pudding. If you want the oats to be thinner in consistency, add additional milk after they’ve sat overnight.
