Expert Tips

We recommend either the 8-ounce or 16-ounce mason jars. The 8-ounce mason jars are compact and will be packed tightly, making them easy to put in a purse or backpack. The 16-ounce jars will give you some room to stir and eat without it spilling out.
You can enjoy this delicious "overnight" oats jar immediately or put it in the refrigerator overnight. It will continue to thicken the longer it sits. If it's too thick for you, feel free to hit it with a splash of plant-based milk right before eating.
Wondering what to do with the rest of the lemon you zested? Use it to make a salad dressing, such as Tahini Lemon Sauce, Green Goddess Dressing, or Vegan Caesar Salad.

Recipe FAQs

How do I store leftovers?

Leftovers store well in an airtight container in the refrigerator for up to 3 days.

What not to add in overnight oats?

We don't recommend adding refined or brown sugar. The added sugar adds calories and no helpful micronutrients. Instead, your best bet is to use pitted dates or our Homemade Date Syrup recipe that is unrefined. Dates provide nutrients not found in other sweeteners like refined syrups and sugar. They are a great source of potassium, copper, and magnesium. They also contain fiber.

Can I use frozen blueberries in these overnight oats?

Absolutely! Frozen berries are a great solution, especially when berries are not in season.
