Quick oats vs. rolled oats vs. steel-cut oats

When it comes to making a bowl of oatmeal, there are a few different types of oats you can choose from to use. Each type of oats has its pros and cons, and you can choose whichever you like depending on your personal preference.

Quick oats

Quick oats are made by steaming them for the longest period of time, then rolling them and cutting them thin. Quick oats are the more processed type of oats, though they are still packed with nutritional benefits. Quick oats have a soft texture when cooked and cook the fastest.

Rolled oats

Rolled oats are steamed for a shorter period of time and then rolled into flakes. When cooked they have a chewier texture than quick oats and will take slightly longer to cook.

Steel-cut oats

Steel-cut oats are groats of whole oats that have been chopped into smaller pieces. They have the best nutritional profile of all the oats and are the least process. They take the longest to cook and

Peanut butter oatmeal ingredients

ingredients for peanut butter oatmeal
  • Oats: you can use quick oats, rolled oats or steel-cut oats. The recipe directions are for quick oats, so if you use a different type of oats you’ll need to adjust the cooking time. Use gluten-free certified oats if needed.
  • Milk: I use almond milk, but you can use any type of milk you like. This adds some creaminess to the oatmeal.
  • Water: if you prefer to use all milk you can use all milk. I like to use half milk and half water so the oatmeal is creamy, but not too creamy.
  • Peanut butter: creamy or crunchy both work. I use natural peanut butter. You can substitute any type of nut butter such as almond butter or cashew butter.
  • Honey: just a drizzle for some sweetness. You can also substitute with maple syrup, agave nectar or brown sugar.
  • Salt: just a pinch to bring out the flavour of the peanut butter. If your peanut butter already contains salt, leave out this ingredient.

How to make peanut butter oatmeal

Step 1

How to store oatmeal

If you prepare this oatmeal ahead of time or have extras, you can store the oatmeal in an airtight container in the fridge for up to 3 days.

Reheat the oatmeal in a small pot on medium heat or in a bowl in the microwave. The oatmeal will thicken as it sits in the fridge, so you may need to add an additional 1/4 cup of water to the oatmeal as you reheat it.

Expert tips for making peanut butter oatmeal

  • For even more flavour, toast the oats in the pot for about 1 minute before adding the rest of the ingredients. This will give the oatmeal an extra toasty flavour!
  • Stir often as you cook. This will prevent the oatmeal from sticking to the bottom of the pot and will help to create a light and fluffy oatmeal.
  • Add more liquid as needed. The longer the oats cook, the more liquid they will absorb and the thicker they will get. If your oats have become too thick, just add some more water and stir.
  • Serve immediately. Oatmeal is always best served right away after it comes off the stove.
