Pressure Cooker Apple Cinnamon Oatmeal

Many pressure cooker manuals instruct you not to cook the oats, since they can foam up and clog the pressure release mechanisms, but Instant Pot says you can cook the oats as long as the pot is no more than halfway full.

If you're using a stovetop pressure cooker, you may have more issues with scorching, as well as clogging the pressure release, since they cook at higher pressure.  Cook time for a stovetop cooker would be for ten minutes shorter and allow the pressure to release naturally and completely before opening, to avoid any risk of a bubbly mess.

  • Prep time: 5 minutes
  • Cook time: 35 minutes
  • Yield: 6 servings


For the oats:

  • 2 tablespoons unsalted butter or coconut oil
  • 1 1/2 cups steel cut oats
  • 4 1/2 cups water
  • 1 large Granny smith apple or other firm apple, peeled and diced (about 1 1/2 cups diced)
  • 1/4 cup brown sugar or maple syrup
  • 1 teaspoon ground cinnamon
  • 3/4 teaspoon salt

For serving:

  • Butter
  • Brown sugar or maple syrup
  • 3/4 cup toasted, chopped nuts (pecans or walnuts)

Special equipment:


1 Toast the oats: Select the Sauté setting on your electric pressure cooker and melt the butter. Add the oats and cook, stirring often, for about 5 minutes, until the oats are aromatic and lightly toasted.

2 Pressure cook the oats: Stir the water, apple, brown sugar or maple syrup, cinnamon, and salt into the oats, making sure all of the oats are submerged in the liquid.

Secure the lid on the pressure cooker, making sure that the pressure release is set to its sealing position. Cancel the Sauté program, then select your pressure cooker’s Manual setting and set the cooking time for 12 minutes at high pressure. (The pot will take about 10 minutes to come up to pressure before the cooking program begins.)

3 Release the pressure naturally for 10 minutes: When the cooking program ends, let the pressure release naturally for at least 10 minutes, then move the Pressure Release to Venting to release any remaining steam. Open the pot and stir the oatmeal to incorporate any extra liquid.

4 Serve the oats: Ladle the oatmeal into bowls and top with butter, brown sugar or maple syrup, and chopped nuts. If the oatmeal thickens up after sitting, thin it out with a splash of milk.

This recipe makes quite a bit and you may have leftovers. The easiest way to reheat an individual serving of oatmeal is in the microwave. Heat in a microwave-safe bowl for 2 to 3 minutes, until piping hot. The oatmeal will have thickened—stir in a splash of milk to thin it out again.
