This make-ahead method is perfect for busy mornings and meal prep—simply portion and refrigerate for a week of ready-to-eat breakfasts.
Slow Cooker Steel Cut Oats
Steel cut oats have a chewier texture and nuttier flavor than rolled oats, but they require more cooking time on the stovetop. The slow cooker is ideal for steel cut oats because you can “set it and forget it”—a hands-off way to achieve creamy oats without constant stirring. If you prefer faster methods, steel cut oats also cook quickly in an electric pressure cooker or Instant Pot, but the slow cooker yields a reliably tender, custard-like texture with minimal effort.
Steel cut oats are also a nutritious choice. A typical 1/4 cup serving of dry steel cut oats contains about 7 grams of protein and offers more fiber than many more processed oat varieties. This makes them a satisfying and filling breakfast option when paired with nutrient-rich toppings like fruit, nuts, and nut butter.
Full-Fat Coconut Milk
Full-fat coconut milk is the secret to the ultra-creamy texture and pronounced coconut flavor in this recipe. While light coconut milk or other milks will work, the full-fat version adds richness and a silky mouthfeel that really elevates the dish. We tested both light and full-fat options and the full-fat coconut milk produced the most satisfying result.
This recipe uses a combination of milk and a can of full-fat coconut milk. At first it may look like too much liquid, but the oats absorb the liquid as they cook and the finished texture is thick and creamy. One cup of uncooked steel cut oats generally yields four servings; this recipe is scaled to serve six. You can halve or double the recipe to match your slow cooker size and household needs. Leftovers store well—refrigerate portions in airtight containers for quick breakfasts all week. Pro tip: these oats are pleasant eaten warm or cold.
Oatmeal Toppings & Serving Suggestions
Once the oats are cooked, top them with your favorite mix-ins for added flavor, texture, and nutrients. Popular combinations include:
- Dried coconut flakes or toasted coconut
- Fresh berries (strawberries, blueberries)
- Sliced banana or diced apple
- Chunks of pineapple for a tropical twist
- Sliced almonds, chopped walnuts or pecans
- A spoonful of nut butter (peanut, almond, cashew)
- Granola for crunch
- A drizzle of honey or maple syrup if you prefer extra sweetness
- A pinch of cinnamon or a splash of vanilla for warmth
Recipe: Slow Cooker Creamy Coconut Steel Cut Oats
Recipe Details
Prep: 10 mins | Cook: 6–8 hrs low (or 2–4 hrs high) | Servings: 6
Ingredients
- 1.5 cups steel cut oats
- 1 (15-oz) can full-fat coconut milk
- 4.5 cups milk (dairy or plant-based — any will work)
- 1 teaspoon vanilla extract
- Optional: 2 tablespoons maple syrup
- Pinch of salt
Instructions
- Spray or lightly grease the inside of your slow cooker with nonstick spray or a thin coat of oil.
- Combine the steel cut oats, full-fat coconut milk, milk, vanilla extract, maple syrup (if using), and a pinch of salt in the slow cooker. Stir to combine.
- Cook on low for 6–8 hours or on high for 2–4 hours. If possible, stir once or twice during cooking to prevent sticking, though it will usually be fine unattended.
- When the oats are tender and creamy, taste and adjust sweetness or salt as needed. Serve warm with desired toppings and a sprinkle of cinnamon if you like.
Tips & Notes
- Nutrition information below is based on using unsweetened vanilla almond milk and omits optional maple syrup.
- Store leftovers in airtight containers in the refrigerator for up to 5 days. Reheat gently on the stove or in the microwave with a splash of milk to loosen the texture.
- To make this dairy-free, use only plant-based milk. For extra creaminess, keep the full-fat coconut milk.
- If your slow cooker runs hot, check the oats earlier to prevent overcooking. Cooking times can vary by appliance.

Variations & Flavor Ideas
Customize this base recipe in countless ways: stir in mashed banana and cinnamon for a banana-cinnamon version; add cocoa powder and a dairy-free chocolate protein powder for a chocolate coconut oatmeal; or fold in lemon zest and fresh berries for a bright summer bowl. Add seeds like chia or flax at the end for extra fiber and omega-3s. The slow cooker method is forgiving and ideal for experimenting with flavors.
Storage and Reheating
Portion cooled oats into individual containers for quick breakfasts. Refrigerate up to 5 days. Reheat on the stovetop over low heat with a splash of milk or water, stirring until warmed through, or microwave in a covered bowl for 60–90 seconds, stirring halfway through. Add fresh fruit, nut butter, or a sprinkle of toasted coconut before serving.
