Best Oatmeal Cooking Methods

Cooking oatmeal is as easy as pouring love into a bowl. Let’s keep it simple and delightful. Here are 5 ways to cook oatmeal using the most common types of oatmeal.

How To Cook Oatmeal In Microwave

Cooking oats in the microwave is a convenient and quick way to prepare a healthy breakfast. Here’s a simple guide to cooking both quick oats and old-fashioned oats with water in the microwave.

Quick Oats

Ingredients:

  • 1/2 cup quick oats
  • 1 cup water
  • A pinch of salt (optional)
Cooking quick oats in the microwave.

Instructions:

  1. Combine Ingredients: In a microwave-safe bowl, combine 1/2 cup of quick oats, 1 cup of water, and a pinch of salt if desired.
  2. Microwave: Place the bowl in the microwave and cook on high for 1-2 minutes. Start with 1 minute, then check the consistency. If the oats are too watery or undercooked for your liking, continue to cook in 15-30 second intervals until the oats are tender and the water is absorbed.
  3. Stir and Rest: Stir the oats well after cooking to ensure even consistency, then let them sit for about 1 minute to thicken slightly.
  4. Serve: Enjoy your oatmeal plain or with added milk and your favorite toppings like fruit, nuts, or sweeteners.

Old-Fashioned Rolled Oats

Ingredients:

  • 1/2 cup old-fashioned oats
  • 1 cup water
  • A pinch of salt (optional)
Cooking old fashion rolled oats in the microwave.

Instructions:

  1. Combine Ingredients: In a microwave-safe bowl, combine 1/2 cup of old-fashioned oats, 1 cup of water, and a pinch of salt if desired.
  2. Microwave: Place the bowl in the microwave and cook on high for 2.5 to 3 minutes. Start with 2.5 minutes and check the texture. If the oats need more cooking, continue in 15-30 second intervals until they reach your desired consistency.
  3. Stir and Rest: Stir the oats thoroughly after cooking and let them sit for 1 minute. This allows the oats to absorb any remaining water and thicken up.
  4. Serve: Serve your oatmeal hot, plain, added milk or any desired toppings, such as fresh berries, honey, or a sprinkle of cinnamon.

Tips for Cooking Microwave Oatmeal

  • Adjust Cooking Time: Microwave wattages vary, so you may need to adjust the cooking time slightly based on your microwave. Keep an eye on your oats as they cook to avoid overflows.
  • Use a Large Microwave-Safe Bowl: Oats can bubble up as they cook, so use a bowl that’s large enough to prevent overflow.

Cooking Oatmeal On Stovetop

Prepping Overnight Oats

Overnight oats are a simple, no-cook breakfast option that’s perfect for busy mornings. By soaking oats in liquid overnight, they soften and absorb the flavors, resulting in a creamy, delicious meal that’s ready to eat when you wake up. Here’s a basic guide on how to prepare overnight oats.

Basic Overnight Oats Recipe

Ingredients:

  • 1/2 cup old-fashioned rolled oats
  • 1/2 cup milk (dairy or non-dairy, such as almond, oat, soy, or coconut milk)
  • 1 tablespoon chia seeds (optional, for extra thickness and nutrition)
  • 1 tablespoon sweetener (such as honey, maple syrup, or agave, optional)
  • 1/2 teaspoon vanilla extract (optional, for flavor)
  • A pinch of salt (optional)

Instructions:

  1. Combine Ingredients: In a mason jar, bowl, or container with a lid, combine the 1/2 cup of old-fashioned rolled oats, 1/2 cup of milk, 1 tablespoon of chia seeds (if using), 1 tablespoon of sweetener (if using), 1/2 teaspoon of vanilla extract (if using), and a pinch of salt.
  2. Mix Well: Stir all the ingredients together until the oats are fully coated and well combined with the liquid.
  3. Cover and Refrigerate: Cover the jar or container with a lid or plastic wrap and place it in the refrigerator. Let the oats soak overnight. This soaking time allows the oats to absorb the liquid and soften.
  4. Serve: In the morning, give the oats a good stir. If they are too thick for your liking, add a splash of milk to loosen them up. Top with your favorite fruits, nuts, seeds, or any other toppings you enjoy.
  5. Enjoy: Overnight oats are typically enjoyed cold, but you can let them sit at room temperature for a few minutes if you prefer them slightly warmer.

How to Cook Oatmeal In Instant Pot

Steel-cut oats are a hearty and nutritious breakfast option that offers a chewy texture and nutty flavor. Cooking them can take some time on the stovetop, but an Instant Pot can speed up the process significantly.

Instant Pot Steel-Cut Oatmeal

Ingredients:

  • 1 cup steel-cut oats
  • 3 cups water
  • A pinch of salt (optional)
Cooking steel cut oats in an instant pot.

Instructions:

  1. Prepare the Instant Pot: Add 1 cup of steel-cut oats, 3 cups of water, and a pinch of salt (if using) to the Instant Pot.
  2. Seal the Lid: Secure the lid on the Instant Pot and set the valve to the sealing position.
  3. Set Cooking Time: Select the “Pressure Cook” or “Manual” button and set the timer for 4 minutes on high pressure.
  4. Natural Release: Once the cooking time is up, allow the pressure to release naturally for about 10 minutes. This helps the oats finish cooking and prevents any splattering if the steam is released too quickly.
  5. Release Remaining Pressure: After 10 minutes, carefully turn the valve to the venting position to release any remaining pressure. Remove the lid once the pin drops.
  6. Stir and Serve: Give the oatmeal a good stir to combine and thicken. Serve hot with your favorite toppings like fresh berries, nuts, sweeteners, or spices.

  1. I don’t know why people say to add the oats after the water is boiling. Add the oats to the water at the start and as it comes to a boil the oats will be done much more quickly!

  2. I almost died eating this. I love this so much. It sent me to the ER. My child who is fatherless was almost scared to death like me. But thankfully I eat more so I didn’t need to take care of him anymore. He lives with this Grandparents who are supportive and very good. Thank you for everything Oatmeal Recipe. 10/10
