These basic overnight oats with flaxseed are easy to make and they’re great for meal planning. They contain just five simple ingredients. This is a simple recipe for overnight oats that can be adapted to your flavor preferences. They're perfect for a make-ahead easy breakfast for school or work.
How to Make Overnight Oats with Flaxseed
Overnight oats use old-fashioned rolled oats that soak in milk to soften the grain. It’s a no-cook method to enjoy a cold breakfast. Use milk for the flavor and creaminess, just let the oats soak for a couple of hours or leave them overnight to soften.
This easy breakfast usually contains chia seeds or flax seeds to soak up the milk and thicken the mixture. I like to add them to get my daily dose of omega-3 fatty acids. You can find a plethora of information on the benefits of ground flax seeds at Nutrition Facts. If you’re interested, it can also lead you down a rabbit hole of flax seed videos.
Rest assured that they will last for about 5 days, so you can make enough flaxseed overnight oats for the entire work/school week. I like the simplicity of raisins or peanut butter because they’ll last longer than using fresh fruit in overnight oats.
I’ve come to learn that some of the more fragile fresh fruits (like strawberries) are really better eaten within one to two days. Using raisins or peanut butter means I can just prep once for the whole week.
Yes, flaxseed and chia seeds can be substituted for each other in overnight oats.
- If the portion is too small then increase the oats to however much you want and increase the milk by the same amount.
- Just grab one serving out of the refrigerator, pair it with a piece of fruit and you have a healthy breakfast.
- I prefer a 1:1 ratio for oats and dairy-free milk, but if you prefer a thinner consistency then add a splash of milk before serving.
- Depending on how sweet you like your oats, try 1-2 teaspoons of maple syrup. The raisins alone may make it sweet enough for you.
- Make sure to use ground flax seeds, whole seeds may pass through you undigested, which means you won’t reap all of the benefits from them.
- You can substitute ground flax seeds for ground chia seeds.
Using Jars for Overnight Oats
They don’t have to be made in jars, use any kind of container with a lid. If your family loves peanut butter as much as we do, you probably have a few peanut butter glass jars.
The brand I buy uses a wide-mouth glass jar so it’s a little easier getting a spoon in there. Also, my frugal side feels like I just won a free gift every time I buy peanut butter in a glass jar. I keep the jar, wash it out, and remove the label. Boom, I’ve got a new storage container.
