Dear slow cooker, it has been way too long since you’ve last come out to play. I am so glad to have you back in my life. Love, Lee.

Oatmeal-Obsessed

If you love oats as much as I do, this recipe belongs in your rotation. Steel-cut oats deliver a hearty texture and nutty flavor that shine when simmered slowly. Making steel-cut oats on the stove usually requires attention and frequent stirring, but using a slow cooker transforms the process: you add the ingredients, stir once or twice, and come back hours later to perfectly cooked oatmeal that’s ready to serve.

Let’s Talk Apple Cinnamon

Apple and cinnamon are a classic pairing for a reason. The apples bring subtle sweetness and moisture while cinnamon adds warmth and depth. A small trick that makes a big difference is shredding the apples rather than dicing them. Shredded apple distributes into the oats and melts into the porridge, infusing every spoonful with apple flavor while maintaining pleasing texture.

Ingredients you’ll need:

  • 1 1/2 cups steel-cut oats
  • 3 cups plain, unsweetened almond milk
  • 3 cups water
  • 1/3 cup maple syrup (or sweetener of choice)
  • 2 teaspoons ground cinnamon
  • 1/8 teaspoon sea salt
  • 2 large apples, peeled and shredded (Gala, Honeycrisp, or your favorite)

How to Serve

This oatmeal is versatile—adjust the final texture and toppings to match your preference. If you like a looser, creamier bowl, stir in a splash of almond milk or regular milk just before serving. For added protein and richness, top with a spoonful of nut butter. Add some crunch with chopped walnuts, pecans, or a sprinkle of toasted seeds. A little extra shredded apple and a dusting of cinnamon make a simple, elegant finish.

  • Add a splash of milk for creaminess.
  • Stir in nut butter and top with shredded apple.
  • Garnish with walnuts and a pinch of cinnamon for texture.

Storage

Allow the cooked oatmeal to cool to room temperature, then transfer it to a sealed glass container and refrigerate for up to five days. Reheat single servings in the microwave or on the stovetop, adding a splash of milk or water to loosen the porridge. To freeze, portion into airtight containers and store for up to three months; thaw overnight in the refrigerator and reheat gently.

Prep: 10 mins   Cook: 6 hrs (low) / 3–4 hrs (high)   Total: 6 hrs 10 mins   Servings: 6

Ingredients

  • 1 1/2 cups steel-cut oats
