The Ultimate Guide to Perfectly Thickened Oatmeal

Love thick oats for breakfast and want to learn how to achieve perfectly thickened oatmeal?

As an oatmeal fanatic, I love eating oats in all forms. Whether it’s banana bread, overnight oats, granola, or baked oats, I love oats at anytime of the day.

Thicker oats are my personal favorite because they are much more hearty, satisfying, and warming compared to runnier oats.

In this guide, I’ll show you my favorite techniques and ingredients to help you with thickening oatmeal and achieving the perfect texture.

How to Thicken Oatmeal

Liquid Ratio

Use a standard 1:2 ratio of oats to liquid for a thick texture. This equates to 1 cup of oats with 2 cups of liquid. You can adjust slightly if needed, but in my experimentation, this has been the best ratio for thick oats.

Cook for longer

The best way to achieve thicker oats is with time. This slow cooking process, usually taking around 10-15 minutes, allows the oats to absorb the liquid and become creamier.

Protein Powder

I love adding in protein powders after my oatmeal is cooked to thicken up my bowl of oats.

This can include whey, casein, collagen peptides and other plant-based options, which I find significantly thickens my oatmeal.

You’ll want to make sure that you add the protein powder once the oatmeal has cooled off a little bit to avoid cooking and curdling the protein.

Protein powder is also a great addition to make healthy no-bake protein bars and strawberry protein bars.

PbFit

PbFit is essentially defatted peanut butter that is also known as peanut flour which adds a natural nuttiness and thickness to my oats.

It is a great alternative to natural peanut butter that is lower in fat and also easier to mix in. I love also ading PbFit to this easy microwave mug cake recipe for a quick dessert option.

Coconut Flour

Coconut flour is exceptionally rich in dietary fiber. This is one of the main reasons why I like using it to thicken substances like oatmeal.

The high fiber content not only helps thicken the oatmeal but also provides a feeling of fullness to promote digestive health.

Eggs/Egg Whites

When you add beaten eggs or egg whites to your oatmeal, the proteins in the eggs denature (unfold) due to the heat and create a network that thickens the oatmeal.

This network traps liquid and forms a custard-like consistency, adding creaminess and thickness to the oatmeal.

Nut Butter

Nut butters, including peanut butter, almond butter, or other seed butters are inherently creamy and add a natural creaminess to oatmeal.

This creaminess also adds depth and roasted notes to the oatmeal’s texture.

Flax Meal

Flax meal, which is derived from flax seeds, is a very nutritionally dense seed that I like to use when thickening oatmeal and also adding a subtly nutty flavor.

When flax meal comes into contact with the liquid in your oatmeal, it swells and forms a gel-like consistency. This gel traps liquid and expands, thickening the overall texture of your oatmeal.

Dairy and yogurt products

Adding dairy products including yogurt or other milk early in the cooking process of oatmeal is a great way to create a creamier texture.

You can use dairy or non-dairy yogurt depending on your preferences.

In addition to the cooking process, you can also add yogurt as a creamy topping to add more protein and creaminess.

Fruits and Vegetables

You can also use various fruits and vegetable purees, such as applesauce, pumpkin puree, mashed banana, to add thickness and flavor to oatmeal.

Mashed banana is my favorite natural thickener and sweetener. I love mashing a ripe banana and mix it into this single serving serving baked oatmeal because it mixes well to thicken the oats and also adds natural sweetness.

To use any of these purees, simply add them to your oatmeal during or after cooking, depending on your preference, and mix until well combined.

Nutritional benefits of oatmeal

Oatmeal has a wide range of nutritional benefits which makes it a nutritious and wholesome breakfast choice.

It’s notably rich in dietary fiber, which aids in digestion and weight management, and contains heart-healthy beta-glucans that can lower cholesterol levels.

Time-Saving Tips

One of the secrets to achieving a thick bowl of oatmeal is to cook the oats long enough to release all of the starches.

Here are some shortcuts and quick methods to achieve perfectly thickened oatmeal on a time crunch.

Instant Oats:

These oats are pre-rolled and partially cooked, which means they require significantly less time to prepare compared to steel-cut oats.

Instant oats can be ready in just a few minutes compared to 10-15 minutes with rolled oats.

Overnight Oats:

My favorite oatmeal recipe for busy mornings are overnight oats.

Overnight oats are my favorite way to prepare oats in a nutritious manner where they are ready to eat without any cooking required.

Soaking your oats overnight can also help with some of the breakdown with phytic acid, which can reduce mineral absorption and cause gastrointestinal discomfort.

Microwave Oats:

I actually use my microwave to cook my oatmeal 99% of the time.

It is so much easier and works just as well as using the conventional stovetop, which requires stirring and more attention.

Simply combine oats and liquid in a microwave-safe bowl, and heat in 1-minute intervals, stirring in between, until the oats are cooked to your desired thickness.

Instant Pot or Pressure Cooker:

I like using a pressure cooker like an Instant Pot to cook my oats because it cuts down the cooking time just a few minutes in a pressure cooker.

Batch Cooking/Meal Prep:

I love making a large batch of oatmeal in the beginning of the week and being able to simply reheat oatmeal on busy mornings.

Whether it’s using an instant pot, slow cooker, or with overnight oats, meal prepping is the best way to save on time.

The Best Oatmeal Toppings

Some ideas to elevate your oatmeal include a variety of fresh fruits such as strawberries, bananas, raspberries, blackberries, blueberries, peaches, and plums.

Nuts and seeds like almonds, pecans, walnuts, pumpkin seeds, and chia seeds are also great to add a satisfying crunch.

Dried fruits such as apricots, cranberries, raisins, and coconut can provide a sweet and chewy texture.
