How to keep oatmeal from boiling over in microwave

The best way to prevent oatmeal from spilling over in the microwave is to use a deep enough bowl. The walls of the bowl should be at least 3 inches taller than the oatmeal before it is cooked.

If you are using a shallow bowl, microwave the oatmeal in 30 second increments, and keep a close eye until it is finished cooking.

Storage

If you have leftover cooked oatmeal, you can store it in an airtight container in the fridge for up to three days.

Reheat oatmeal in the microwave in a microwave safe bowl for 1 minute, or until warmed all the way through. Add a splash of milk if the oatmeal is too thick and tough.

Questions about oats and oatmeal

Are rolled oats the same as old fashioned rolled oats?

Yes, rolled oats are the same thing as old fashioned oats. The names are used interchangeably.

Rolled oats vs quick oats

Quick oats, also called instant oats, are more processed than old fashioned rolled oats. Quick oats are pre-cooked and pressed quite thin, and cut into smaller pieces than rolled oats. Quick oats cook faster than rolled oats. They have a softer, mushier texture when cooked, as they don’t retain their shape well.

Is oatmeal gluten free?

Gluten is a protein found in a number of grains, including wheat, barley, and rye. All oats are naturally free of gluten. However, oats can become contaminated with grains that do contain gluten during processing.

Additionally, oats may become cross-contaminated with gluten-containing grains prior to processing, because oats are often grown near fields of gluten-containing grains.

If you have celiac disease, I recommend using certified gluten free rolled oats, which are manufactured in a dedicated gluten free facility and tested for gluten levels.

Oatmeal nutrition & health benefits

Oatmeal is affordable, easy to prepare, and highly nutritious. It’s a great food to include regularly in your diet, especially if you follow a plant-based diet because its protein and iron content.

One cup of cooked oatmeal (about 1/2 cup uncooked) provides:

  • 4 grams of fiber (15% of your daily needs)
  • 5.3 grams of plant-based protein
  • 1.7 mg iron (9% of your daily needs)
  • 0.186 mg thiamin (16% of your daily needs)
  • 55.89 mg magnesium (13% of your daily needs)

Oatmeal is one of the best food sources of soluble fiber, which can help lower “bad” LDL cholesterol levels. The main type of soluble fiber in oats is beta-glucan. This type of fiber is linked to health benefits including reduced cholesterol levels and supporting gut health.

Chia seeds nutrition & health benefits

I love to add chia seeds to microwave oatmeal. They make oatmeal, which is already nutritious, even more packed with fiber and micronutrients! Two tablespoons of chia seeds provides:

  • 5.5 grams of dietary fiber, primarily from soluble fiber (20% of your daily needs)
  • 3.7 grams of plant-based protein
  • 0.330 mg thiamin (28% of your daily needs)
  • 78.79 mg magnesium (20% of your daily needs)
  • 0.25 mg copper (28% of your daily needs)
  • 129.04 mg phosphorus (18% of your daily needs)
  • Small amounts of several other essential minerals, including calcium, zinc, selenium, potassium, and iron

In addition, a majority of the fat in chia seeds comes from omega-3 essential fatty acids. This type of fat is essential in our diet because our bodies cannot produce it. Omega-3 fatty acids have heart health benefits, as they can decrease inflammation and help lower cholesterol levels.
