🧄 Ingredient notes
- Blueberries - fresh blueberries are sweet, tart, full of antioxidants and low in calories. They are delicious and healthy topping or mix-in for overnight oats. Frozen wild blueberries are even better, in my opinion, though. They are already washed, which saves you time. Just throw them in the jar. Plus, they keep a long time in the freezer. You don't have to worry about using them quickly, like with fresh berries. And, when the blueberry juice thaws, it is so delicious! It flavors and sweetens the oats for you.
- Blueberry jam - Instead of sugar or maple syrup, we're going for double blueberry flavor by using a bit of blueberry jam to sweeten our oats.
- Old-fashioned rolled oats - Use old-fashioned rolled oatmeal for this recipe. Do not use quick oats for this recipe, they turn out mushy. Don't use steel cut either, since they don't get soft enough to enjoy with this method.
- Plant-based milk - any vegan milk you enjoy should work here, like almond milk (pictured), soy milk, oat milk, coconut milk, cashew milk and rice milk. You can use unsweetened or sweetened original varieties, if you like. Vanilla milk works well, too.
- Ground flaxseed - adds health benefits of added fiber, along with omega-3. Flax also thickens the oatmeal slightly.
- Plant-based yogurt - amps up the creaminess and protein. Vegan yogurts made from cashew, soy, coconut, almond and oat will all work here.
📋 Substitutions and variations
Here are some suitable substitution options for the ingredients:
- Blueberries - use frozen blueberries instead of fresh (add them the night before, so they can thaw overnight). Wild blueberries have a stronger blueberry flavor and work very well in these oats.
- Plant-based milk - Use any plant-based milk you enjoy. Unsweetened, sweetened and vanilla-flavored milks all work in this recipe.
- Blueberry jam - Instead of blueberry jam, sweeten your blueberry oats with maple syrup, agave nectar or sugar. Or omit the sweetener altogether.
- Flax - use chia seeds instead of ground flaxseed. Or, omit them (your overnight oats will be thinner if you omit one of these options).
- Nut-free - make this nut-free by using a nut-free plant milk and yogurt, such as products made using soy, rice or oat.
- WFPBNO - make this whole food plant based no oil by using plant-based milk, yogurt and jam with no added oil or refined sugar.
- SOS-free - make this salt-, sugar- and oil-free by using a plant-based milk, yogurt and jam with no added salt, sugar or oil.
Here are some variation ideas for these blueberry overnight oats:
- Blueberry Almond - add sliced or chopped almonds and a drop of almond extract to the oats
- Blueberry Pie - use premium blueberry pie filling instead of jam and fresh berries for blueberry pie overnight oats
- Mixed Berry - used frozen mixed berry or three berry blend instead of only blueberries
- Blueberry Coconut - add shredded coconut to the oats and use coconut milk as your liquid

⭐️ Expert tips
- If you want to make your overnight oats look pretty, mix them up in a separate container. Then, once mixed, spoon into a jar, glass or bowl and carefully add other toppings to create clean layers. Then, refrigerate. Or, create layers just before eating or serving.
- Use a wide canning funnel to add ingredients to jars without making a mess
- a container to hold your overnight oats that holds 1 pint (about 2 cups, 16 ounces or 550 milliliters). I recommend using wide mouth pint size mason jars.
- measuring spoons and cups
🥡 Make ahead and storage tips
Overnight oats are perfect for meal prep and batch cooking. Make them Sunday night to have breakfast ready to go all week long. Store overnight oats in the refrigerator, combined, for up to 5 days.
This recipe does not stand up well to freezing.
Yes! Add frozen blueberries to overnight oats the night before and it will thaw overnight. I prefer them to fresh blueberries because they keep for months in the freezer and when they thaw the blueberry juice flavors and sweetens your oats. So good!
