Ingredients & Variations

OATMEAL: Steel-cut oats hold up better in an overnight recipe than instant versions do, and also have the highest amount of fiber, B-vitamins, and antioxidants. Quinoa, farro, and bulgar wheat are excellent healthy hot cereals that will also stay firm overnight, but first need to be cooked as directed. Chia seeds help thicken the oatmeal and work well with any of these grains.

MILK: Any milk will do! Almond milk has a mild flavor as does soy and coconut milk, but oat milk is closest to dairy milk for its milk flavor and creamy texture. If choosing plain or flavored yogurt, be sure it’s thoroughly mixed into the oatmeal/chia seed mixture. And be aware that more yogurt may be needed to achieve the right consistency. Evaporated or sweetened condensed milk are not recommended for this recipe.

SEASONINGS: A dash of vanilla, cinnamon, and maple syrup or honey give overnight oats its sweet and savory flavor. Or try this DIY Pumpkin Spice blend for a fun seasonal mix that is also delicious.

ADD-INS: Choose any healthy add-ins like strawberries, bananas, or blueberries. Serve overnight oats plain, or swirl in a spoonful of fruit preserves, or a handful of raisins or dried cranberries. Even the addition of a little chocolate syrup or peanut butter makes a new dish every time! Or add some healthy fats, with a bit of crunch, with chopped pecans, walnuts, pepitas, or slivered almonds.

Tips for the Best Overnight Oats

  • For best results, mix the oats and chia seeds together first. Then use a knife or spoon to thoroughly mix the overnight oats in the jar before refrigerating. This helps the oats and chia seeds soak up the milk.
  • Be sure to use microwave safe containers if heating overnight oats.
  • There is no need to thaw frozen fruit before adding to overnight oats since it will thaw in the mixture overnight.

  • Measure and add to each of four 1 cup mason jars (or other containers)*:
  • ¼ cup steel cut oats
    ⅓ cup almond milk, or milk of your choice
    ¼ teaspoon vanilla
    ½ teaspoon chia seeds
    1 teaspoon maple syrup (or honey)
    ⅛ - ¼ teaspoon cinnamon
    pinch kosher salt
  • Stir the mixture with a spoon or knife and cover with a lid.
  • Refrigerate overnight. Enjoy cold or heat in the microwave if you prefer it warm.


  • *For this recipe, I find it easiest to measure into each jar as I go, however you can also mix it all together and divide into 4 jars.
  • Mix everything together well so the oats and chia seeds can soak up the milk.
  • Add frozen fruit as is because it will thaw overnight.
  • Lasts 5-7 days in the refrigerator.

  1. 5 stars
    I followed the recipe exactly and added fresh blueberries and sliced strawberries in the morning! It was delicious! Definitely making it again tonight 🙂

  2. Is the mixture supposed to look the same as when it when in the fridge? It’s crunchy and maybe a little thicker but not by much.

    1. The oats should be softened, and it will be come thicker as it sits. Oats may vary, so perhaps yours need to sit a little longer to soften. I have made this many times and sometimes it takes a little longer. Hope you enjoy them Wendy!
