Steel cut oats cook in milk and water with apples and cinnamon while you sleep.

Ingredients

  • 2 cups steel cut oats

  • 3 cups water

  • 3 cups whole milk

  • 2 apples, peeled and diced

  • 1/4 cup pure maple syrup

  • 1 tbsp butter, for greasing and stirring

  • 1 1/2 tsp ground cinnamon

  • 1/4 tsp ground nutmeg

  • 1/2 tsp salt

  • 1 tsp vanilla extract

  • 1/2 cup raisins or chopped pecans, optional

  • Extra milk, for serving

Directions

  • Grease the slow cooker insert with half the butter. This prevents the oats sticking to the sides.
  • Add the steel cut oats, water, milk, apples, maple syrup, cinnamon, nutmeg and salt.
  • Stir well to combine.
  • Cover and cook on LOW for 7 hours. Do not use HIGH or the edges will scorch.
  • In the morning, stir the oatmeal well. It should be thick, creamy and tender with a slight chew.
  • Stir in the vanilla and the remaining butter.
  • If it seems tight, add a splash of warm milk.
  • Fold in the raisins or pecans if you like.
  • Serve warm with extra milk and maple syrup.

Notes

    Do not substitute rolled oats. A 6-quart slow cooker is too large for a smaller batch, so use a 3-quart for half the recipe. Use almond or oat milk for dairy-free. Leftovers keep 5 days and reheat in the microwave with milk. Portion into jars for grab-and-go breakfasts.

Why steel cut oats fit overnight cooking

Steel cut oats are chewy and nutty, but they take about 30 minutes on the stove and need stirring. In a slow cooker, they cook while you sleep. Seven hours on LOW turns them creamy and tender, and breakfast for the whole week is ready when you wake up.

The recipe uses a ratio of one part oats to three parts liquid, split between water and milk. Water keeps the texture from getting heavy, and milk adds richness. Apples cook down into soft pieces, and cinnamon and nutmeg make the kitchen smell like fall. One batch makes six servings, which covers most of a work week. Make a double batch only in a larger cooker, since a half-full insert cooks unevenly.

Ingredient notes

Steel cut oats: Use real steel cut oats, which are sometimes labeled Irish oats. Rolled oats and quick oats turn to mush overnight. The oats should look like small, chopped pieces of grain, not flat flakes.

Whole milk: It gives a creamy texture. Low-fat milk works, but oat milk or almond milk may separate, so stick to dairy for the long cook. A pinch of salt keeps the oatmeal from tasting flat, so do not skip it.

Apples: Peel them so the skin does not turn tough. Firm baking apples hold their shape best. Granny Smith apples stay a little tart against the sweet maple. Honeycrisp or Fuji give a sweeter, softer bite.

Maple syrup: Pure maple syrup gives real flavor. Brown sugar is a fair replacement.

Butter, cinnamon and nutmeg: Butter greases the insert, and a small amount stirred in at the end adds shine. Use fresh nutmeg if you can. A teaspoon of vanilla goes in the morning too, since heat dulls the aroma.

Tips for the best result

Grease the insert well: The most common mistake is skipping this. Oats stick and burn along the edges, and scrubbing is no fun in the morning.

Use LOW only: HIGH scorches the edges before the middle cooks. If your cooker runs hot, check at 6 hours. Cooking longer than 8 hours turns the oats gummy, so set it for 7 and let it switch to WARM.

Stir in the morning: The oats separate a bit overnight, and a good stir brings the texture together. Add warm milk to loosen if it looks tight. Taste before serving. A pinch more salt or a drizzle of maple syrup can fix a flat bowl.

Steel cut oatmeal crockpot variations

Swap the apples for diced pears, blueberries or mashed bananas. Add chopped pecans or walnuts in the morning for crunch. For a pumpkin version, replace one cup of the milk with pumpkin puree and use pumpkin pie spice. For a lighter bowl, use all water and no butter, and for a richer one swap a half cup of the water for cream.

Do not put the oatmeal on a timer that starts hours late. The oats can sit raw in the milk for too long. Start it when you go to bed.

What to serve with it

Top with extra maple syrup, a splash of cold milk and a handful of nuts. A side of scrambled eggs or crisp bacon makes it a bigger breakfast. Fresh fruit adds a bright finish. Toasted nuts or a spoonful of nut butter add protein and keep you full until lunch.

Storing and reheating

Leftover oatmeal keeps in the fridge for 5 days. Portion into jars, and add a splash of milk when reheating in the microwave for 1 to 2 minutes. It freezes well for 3 months in single-serve containers. Thaw overnight, then warm and stir.

I read the top-ranked slow cooker recipes for a dish side by side and write down what they disagree on and what they all leave out — the cut, the pot size, and both the LOW and HIGH times. I write these guides so your weeknight dinner doesn't turn into a dry roast because a recipe never said which of those four things mattered.
