Grab These Ingredients

This sweet potato oatmeal uses ingredients you likely already have sitting in your pantry! Jump to the recipe card for exact measurements!

  • Sweet Potatoes: We’ll use these tubers to add natural sweetness and a gorgeous orange hue (oh, and a ton of vitamins A and C!).
  • Steel-Cut Oats: Steel-cut oats provide a hearty texture and a long-lasting energy boost. (They’re usually in the breakfast cereals aisle, next to rolled and quick oats.)
  • Maple Syrup: For a touch of natural sweetness and some bonus antioxidants, we’ll add pure maple syrup. You can also use agave or coconut sugar to keep your oats free of refined sugars.
  • Spice Mix: Ground cinnamon, cloves, and nutmeg add a cozy, warming flavor and come with anti-inflammatory properties, so load up!
  • Vanilla Extract: We’ll kick up the flavor with a dash of pure vanilla extract. You can also add other extracts (like almond, ginger, or hazelnut).
  • Salt: A little pinch of salt goes a long way in balancing the sweetness.

Steel Cut Or Rolled?

When it comes to deciding between steel cut and rolled oats for this recipe, steel cut oats are the clear winner for this recipe. They’re less processed and retain a better shape, providing a chewy, hearty texture. Plus, they absorb liquid gradually, making them ideal for slow cooking. The result? Perfectly thick oatmeal that doesn’t turn mushy!

Ingredients needed for sweet potato oatmeal.

Let’s Make Oats!

Making slow cooker sweet potato oatmeal is as easy as pie (and it tastes like it too)! This is a quick overview, but you can jump to the recipe card for the full printable recipe.

  1. Cook the sweet potatoes and other ingredients until tender.
  2. Mash up the sweet potato pieces.
  3. Serve warm, topped with chopped nuts and a sprinkle of brown sugar or your sweetener of choice.

Mashing Is Key

Once cooked, don’t skip mashing the potatoes! This last step releases their natural sweetness and creates a creamier texture. You can customize the creaminess level—mash them fully for smooth oats or leave some chunks for a more rustic bowl of gruel (as we like to call it in our house).

When ready, the sweet potatoes should be fork-tender and easy to mash. You can use a potato masher, a potato ricer, or a fork for this part!

Customize It!

It’s so easy to customize by adding different mix-ins or toppings. Toss in chopped apples or pears for a fruity twist, or use butternut squash instead of potato. You’ve got options!

Notes

*If cooking for the full 8 hours, I’d advise checking on it around 6 hours to ensure it has enough liquid. If your slow cooker has an auto-off or auto-warm function, set it for 6 hours to prevent scalding.
To cook this on the stove, add everything to a large pot, cover it, and let it simmer for 20 to 30 minutes, or until the oats are cooked and the sweet potato is tender.
For an extra creamy texture, add a splash of milk (regular or dairy-free) before serving or increase the water content slightly during cooking.
Add toppings (like nuts and fresh fruit) after cooking to keep them crunchy and fresh, but you can add dried fruits beforehand to soften them up.
Store any leftovers in an airtight container in the fridge for up to 4-5 days. When reheating, give the oats a good stir and add a splash of water (or milk) to get that creamy consistency back!
Freezer Storage: You can also portion out the oatmeal into freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating.

    Wonder how I could increase the fiber and protein in this recipe without adding many calories.

    1. Sarah Bond says:

      Great question! A few easy ways to boost both without adding many calories: stir in a scoop of unflavored or vanilla protein powder before serving, or swap some of the liquid for unsweetened soy milk, which has more protein than other plant milks. For fiber, try adding a tablespoon of chia seeds or ground flaxseed at the start of cooking since they blend right in without changing the texture much. Hemp seeds sprinkled on top at serving are another great option as they add both protein and fiber with just a small amount. Hope that helps!

    I don’t like steel cut oats. Can I use old fashioned oats?

    1. Sarah Bond says:

      You can use old-fashioned oats, but they will likely cook a lot quicker and need less liquid.
