My reliable Overnight Steel Cut Oats

Oats are one of my all-time favorite breakfasts. I ate overnight oatmeal almost every morning throughout my four years of college, and it’s still a breakfast I come back to often (although I do love a good acai or yogurt bowl in the warmer months!).

For me, the best bowl of oats has to be ultra creamy (I can’t do thick, stodgy oats!), evenly sweetened on its own without relying on toppings, and loaded with all the good stuff. I’m talking creamy nut butter, fresh fruit, a drizzle of something sweet, and a handful of chopped nuts for crunch!

These oats check every box! They’re sweet enough to enjoy plain, have the BEST creamy texture (as long as you don’t overcook them!), and couldn’t be easier to make. They’re reliable for feeding a crowd or meal prepping breakfast for the week.

One thing to know: They thicken as they sit, so I always keep some milk on hand to loosen them up as needed, especially when reheating.

All the ingredients in this recipe prepped out for straightforward assembly including the apples, oats, coconut milk, water, brown sugar, maple syrup, cinnamon, salt, and vanilla.

Ingredients

IngredientLet’s Chat About It
ApplesHoneycrisp are a reliable! Peel and core them before adding. They soften enough to mash evenly right into the oats.
Steel-cut oatsUse regular steel-cut oats, not quick-cooking or instant. The wrong type of oats will become mushy during the long cooking time.
Coconut milk & waterUse canned, full-fat coconut milk, not refrigerated coconut milk. Stir well to distribute everything evenly.
Brown sugar & maple syrupStart with the amounts listed, then taste after cooking. The apples add natural sweetness, too!
Cinnamon, salt & vanillaAdd cinnamon & salt before cooking, but save the vanilla for the end for the best flavor.

Storage

How To Meal Prep This Overnight Steel Cut Oats Recipe

  • To store: Refrigerate cooled oats in airtight containers for up to 4 days. It is satisfying to using these containers to prep out several for breakfasts throughout the week.
  • To reheat: Microwave with a splash of milk, stirring until warm & creamy.
  • To freeze: Freeze individual portions for up to 2 months. Thaw overnight in the fridge before reheating.

My tip: Store toppings separately so fruit stays fresh, nuts stay crunchy and you can switch things up each morning!
