You’ll love crockpot oatmeal because you wake up to a hot bowl of oatmeal, a hearty healthy breakfast. What could be better than that? It’s comforting, warm, and filling.

Eating oatmeal can feel a little old-fashioned. Oats have been around for thousands of years. You may know oatmeal as porridge or by another name. The Scots have been eating oatmeal for centuries because growing oats is well-suited to their climate. I’m reminded of a funny episode in The Outlander series when Jamie tells the French king his digestive problems could be solved with a morning bowl of porridge.

If you have only tried instant oatmeal from the little packets, you’ll be very pleased to discover that crockpot oatmeal is so much better than that! There’s really no comparison.

What Are Steel Cut Oats?

Oat groats (the whole grain) are milled in a variety of ways. For steel cut oats, the groats are chopped into little pieces. They look like small pieces of brown rice. Steel cut oats, also known as Irish oats or Scottish oats, have a chewier texture than old-fashioned oats which are steamed first, then rolled into small flat disks. Steel cut oats require a longer cooking time.

Why You’ll Love Crockpot Oatmeal

A cinch to make! This oatmeal is so easy to stir up the night before. You only need oats, water, and a pinch of salt. And a crockpot, of course. Five minutes max!

Eliminates breakfast prep in the morning. When you’re ready for breakfast, just lift the lid off your slow cooker, spoon steaming hot oatmeal into your bowl, top with anything you like, and eat! No half-awake breakfast-making. No standing by the stove, stirring a pot while you listen to your stomach growl.

A healthy start to the day! Why is a breakfast of oatmeal a good thing? Healthline says oats are one of the healthiest grains on earth. Oats are higher in protein than many other grains so they’ll stick with you until lunchtime. Oats are gluten-free, too. (P.S. If you’re not a fan of oatmeal but want to incorporate oats into your morning routine, try my oat flour pancakes. Kids love ’em!)

Ingredient Notes

Steel Cut Oats: No substitutions here; other types of oats won’t work in this recipe. Try our baked oatmeal with rolled (old-fashioned) oats if that’s what you have on hand. Homemade granola is another recipe which uses rolled oats.
Water: A liquid is essential to hydrate the oats. I tested this recipe several different ways, including using milk instead of water, and found that the mixture with milk tends to burn on the bottom and around the edges when it cooks all night in a slow cooker.
Salt: Just a pinch of salt keeps the oats from tasting flat.
Nonstick Spray, Butter, Or Coconut Oil: A little bit of oil will make clean up easy for you.
Slow Cooker (Crockpot): You’ll need a four to six quart crockpot with a lid. If you’re looking for a faster option, you may want to try Instant Pot steel cut oats. The cooking time is shorter, about 30 minutes, and it’s all hands-off time.
Optional Toppings: Milk (either dairy or non-dairy), fruit, dried fruit, seeds, nuts, nut butters, brown sugar, honey, maple syrup, you name it, it’s good on oatmeal. Keep reading for even more topping ideas!

How To Make Crockpot Oatmeal

Prep the slow cooker. Spray the inside of the crockpot with nonstick spray or grease it with butter or coconut oil. This will prevent the oats from sticking to the sides and will be easier to clean up.

Combine and cook. Add the steel cut oats, water, and a bit of salt to the crockpot and stir. Put the lid on, set it for Low, and walk away.

In seven or eight hours, you’ll have perfectly cooked steel cut oats! Have a good night’s sleep!

Serve. In the morning, give the oats a stir and scoop up a bowlful.

Unless you’re really a purist, you’ll want to top the oatmeal with something. Here are a few ideas but don’t be limited by this list.

Topping ideas

Dairy (or non-dairy): Milk, cream, yogurt, non-dairy milk such as almond milk
Sweeteners: Brown sugar, honey, maple syrup, molasses, chocolate syrup (or chocolate chips!)
Spices: Add a sprinkle of cinnamon, nutmeg, or ginger. Pumpkin pie spice or apple pie spice are great additions to oatmeal. Try mild curry powder for something different!
Fruit: Sliced bananas, berries, peaches, and mango are good choices. Apple compote (cooked apples) is one of my favorite things to add to oatmeal. It’s great on French toast or pancakes, too!
Dried fruit: Raisins, dried cherries, dried apricots, dates, figs
Toasted nuts and seeds: Walnuts, pecans, almonds, pepitas, and sunflower seeds. Toasting the nuts first adds extra flavor and it’s easy to do. For an extra special breakfast, garnish the oatmeal with spiced pecans.
Nutrition boosters: Try ground flaxseed, chia seeds, wheat germ, and nut butters.
Eggs: Add a fried egg to your bowl of oatmeal for a more savory treat.

Do You Soak Steel Cut Oats?

This is a common question. Soaking steel cut oats can speed up the cooking time if you are cooking them on the stove. With this crockpot method, it isn’t necessary to soak the oats first because they’ll be cooking all night. By the way, you don’t have to rinse steel cut oats before cooking them, either, unless the package instructs you to do so.

Rather Have Oatmeal Cookies?

I get that! Try these crispy coconut oatmeal cookies, soft and chewy iced oatmeal cookies, or whole wheat oatmeal raisin cookies. We really love breakfast cookies made with whole wheat flour and oats for breakfast on-the-go or a healthy snack. Energy balls are high in protein and are usually made with oats, too. Try cranberry oatmeal energy balls or apple cinnamon energy bites.

If you’re loving the idea of crockpot oatmeal, be sure to try carrot cake slow cooker oatmeal or pumpkin pie slow cooker oatmeal.

Make Ahead Ideas

Crockpot oatmeal is a great make ahead recipe because cooked oatmeal can be refrigerated or frozen for a quick and easy breakfast later in the week. Double the recipe if you like! Keep reading for how to freeze and reheat serving size portions.

Storage Tips

Refrigerate: Cooked oatmeal can be stored in a covered container in the refrigerator for up to five days.

Freeze: For serving size portions, freeze the cooked oatmeal in muffin tins sprayed lightly with cooking spray or greased (silicone muffin tins or souper cubes work great for this). Once it’s frozen, pop the oatmeal out of the tins and put the disks into freezer bags. It will keep for up to six months. To reheat, put one into a microwave safe bowl and heat for 1 to 2 minutes. Bingo, breakfast is ready!

How to store uncooked oats: Oats should be kept in an airtight container in a cool dark place. They’ll keep for at least 12 months or even longer.
