How to Cook Oat Groats
Learn how to cook oat groats using the stovetop, Instant Pot, slow cooker, or rice cooker. This guide includes water ratios, cook times, and tips for making tender oat groats for sweet breakfasts, savory grain bowls, or simple side dishes.
Servings: 4 servings
Ingredients
- 3 cups water
- 1 cup whole oat groats rinsed
- 1 teaspoon salt
Instructions
Stovetop Directions
- Add the water, oat groats, and salt to a medium-sized saucepan. Bring the pot to a boil, then reduce the heat to medium and place the lid on the pot.
- Cook for 45 minutes for a slightly chewy texture or 60 to 70 minutes for a soft, creamy texture.
- If there is any liquid left in the pot, drain it off. See notes for topping ideas.
Instant Pot Directions
- Add 2½ cups water, oat groats, and salt to the Instant Pot. Close the lid and set the valve to seal.
- Cook on high pressure for 15 minutes for a slightly chewy texture or 22 minutes for a softer texture.
- Let the Instant Pot do a natural pressure release for 10 minutes. Taste-test the oats to determine if you like the texture. If you prefer a softer texture, replace the lid and cook for an additional 5 to 10 minutes (make a note of your desired cook time for the next time you make oat groats in the Instant Pot).
- If there is any liquid left, pour it out.
Slow Cooker Directions
- Place the water, oat groats, and salt in a slow cooker.
- Cover the pot and cook on low for 4 to 6 hours or on high for 2 to 3 hours. Slow cookers vary in temperature and timing. Check the doneness of the oats and adjust the cooking time according to your slow cooker.
Oat Groats in the Rice Cooker
- If you have a smaller rice cooker, some of the liquid may foam up and bubble over as it cooks. Place the rice cooker on a plate or tray to catch any liquid that may bubble over.
- Add the water, oat groats, and salt to the rice cooker.
- Place the lid on the rice cooker and push the tab down to start the cooking. The tab will pop up when the oat groats are finished cooking. If your rice cooker has a timer, set the timer for 45 minutes.
- Taste-test the oats. If you prefer a softer texture, add 1/2 cup of liquid and push the tab down to cook more.
Notes
Use 3 cups of liquid for the stovetop, slow cooker, and most rice cookers. Use 2½ cups for the Instant Pot.
Chicken or beef broth makes a good substitute for water when serving oat groats as a savory side dish or grain bowl.
Storage: Store cooked oat groats in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months. Reheat with a splash of water, milk, or broth to loosen the grains.
