How to make oatmeal on the stove with water and/or milk – a delicious basic oatmeal recipe perfect for adapting and topping hundreds of ways! Plus, it can be made gluten-free, dairy-free, vegan!

I recently started sharing my morning breakfasts on Instagram, including several simple oatmeal recipes (like this Healthy Banana Oatmeal and Berry Oatmeal). No matter how I ‘fancify’ my oats, though, I tend to use a basic oatmeal recipe as my base, which is why I thought I’d share my method for how to make oatmeal on the stove – for creamy, delicious results every time!
I always have jumbo-sized bags of oats in my apartment; whether I’m using them for overnight oats, blueberry baked oatmeal, healthy oatmeal cookies, sprinkling them into smoothies, or using them to make this basic oatmeal (aka oat porridge), there’s definitely no lack of inspiration for oat recipes in this apartment.

Oatmeal porridge is warm, comforting, wholesome, healthy, and easily customizable – what’s not to love? In fact, oats are not only 100% whole grain, but they also contain several vitamins and minerals, are rich in antioxidants, and are full of fiber – to help keep you fuller for longer. Best of all, they’re naturally gluten-free and vegan!
When prepared correctly, a big bowl of oatmeal porridge will be thick and creamy without being mushy, gluey, or too chewy. Within this post, I’ll take you through my preferred oatmeal to water ratio, how to make oatmeal with milk and/or water, as well as several easy add-ins to the oatmeal basic recipe.

The Oatmeal Ingredients

- Rolled oats – make sure to use certified gluten-free, if necessary. Different types of oats will affect the cooking time, read the FAQs for more on that.
- Water – I use a combination of water and milk when making my basic vegan oatmeal. Feel free to use all milk or water if you want it creamier vs. lower calorie.
- Milk – I tend to use oat milk for oatmeal porridge, but feel free to swap this with your dairy free milk of choice. (i.e., homemade almond milk or simple homemade rice milk) or even dairy.
- Salt – just a pinch will really enhance the flavor of the oatmeal, so don’t omit this.
Optional Add-Ins
Obviously, there are tons of ways to adapt and top the simple oatmeal recipe. These add-ins aren’t about adding tons of flavor, instead, they are ways to adapt your ‘base’ easily and still be able to top or flavor with whatever you’d like.
- Add protein to oatmeal: it’s very easy to add protein to oatmeal with the addition of 1 Tbsp chia seeds/flaxseed or this 5-Seed DIY Vegan Protein Blend or omega seed mix. You could also add a scoop of your favorite plain (or flavored) protein powder.
- Hidden veggie: I love to add finely grated zucchini to my basic oatmeal recipe. As it cooks, it disappears into the oatmeal and is neutral enough in flavor that you can’t taste it. I suggest adding around 1/2-1 cup of the grated zucchini per 1/2 cup of oats used.
- Sweetener: use the sugar/sweetener of your choice: maple syrup, agave, cane sugar, coconut sugar, brown sugar, or the classic ‘golden syrup’ in the UK.

Simple Flavorings
- Nut butter – for flavor and protein, add 1-2 spoonfuls of your favorite nut butter recipes.
- Chopped dried fruit: dates, raisins, cranberries, apricots, etc.
- Shredded apple or other fresh fruits.
- Crushed nuts: pistachios, walnuts, pecans, almonds, etc.
- Chocolate: You can add healthy dark chocolate (paleo, vegan recipe), or your favorite chocolate of choice.
- Vanilla extract: this makes for a wonderful base for tons of toppings. I use homemade vanilla extract and just add enough, to taste.
- Spices: if I plan on topping my oats with fruits and etc, I’ll often add a little something extra to my base oats: cinnamon, nutmeg, cardamom, pumpkin spice, etc.
- Coconut: either shredded coconut, coconut flakes, or even coconut butter (for healthy fats and flavor) will add texture and a little flavor. Perfect for pairing with fruits, nut butter, chocolate, etc.
How To Make Oatmeal On The Stove
The Oatmeal To Water Ratio
The most important thing for this simple oatmeal recipe is to make sure you use the correct ratio of liquid to oats.
The standard ratio is 1:2 oats to liquid (1/2 cup oats with 1 cup water and/or milk- you can use either or both combined). This ratio makes thick and fluffy oats.

Personally, I prefer my oats to be a little ‘wetter’, so I use 1 1/4 cup liquid in total: 1 cup water and 1/4 cup milk added towards the end of the cooking process.
How To Cook Oatmeal
In a small saucepan, heat up the oats with water and salt. Bring to a boil and then let them simmer over medium heat for 3-4 minutes.
Then, add the milk to the oats mixture, stir and heat for a further 1-2 minutes.

By adding the milk at this point you don’t have to worry about it scalding in the pot and you still get wonderfully creamy results but with only a fraction of the calories. You could alternatively start the process with half water and half milk or all milk. Feel free to reduce the liquid to 1 cup in total if you prefer thicker oats.
Once it’s cooked to your desired texture, pour the oatmeal into a bowl and top with your toppings of choice (like this mixed berry compote).

How Long Does Oatmeal Last?
I prefer to cook oatmeal freshly every day. However, plain oatmeal porridge will last in an airtight container in the fridge for up to 5 days. You can also freeze it for up to 3 months! Make sure to refrigerate it within an hour or two of making it, though. Otherwise, bacteria can start to grow.
Reheat the oatmeal either in the microwave or on the stove. You may need to add an extra splash of water or milk to get it back to the creamy texture.
FAQs
This isn’t something I do often, as I prefer the texture of stovetop oatmeal.
Add all of the ingredients to a bowl, mix well, and then microwave on HIGH for between 2-3 minutes.
Use 1 cup liquid when doing this method and stop the microwave after a minute to stir and then heat for the remaining time.
It’s important to use a bowl with high sides as the water/milk will bubble up as it boils. You could also cover it with cling film with a few steam holes poked in it.
There are three main types of oats used to create oatmeal. Each of them is derived from oat groats, which are then processed into the various forms we recognize.
Steel-cut oats: this type of oat is actually the whole oat groat that’s been cut into several pieces. It looks more like grains like rice or barley than the typical soft oats we’re used to. This type of oat is the least processed. However, it also takes the longest to cook (up to 40 minutes!) and requires more liquid.
Rolled oats: also referred to as old-fashioned oats. These are the most common oats and are the oat groat steamed and rolled into thin flakes that are much faster to cook. These will cook creamy but still have some bite.
Quick-cook oats: also referred to as instant oats. These are actually basically rolled oats that have been cut down into smaller pieces, thus taking a shorter time to cook. Due to the smaller pieces, the texture will also change as it is creamier, with less ‘bite.’
No, this method is specifically for rolled oats (old-fashioned oats). Steel-cut oats usually require more liquid and a lot longer time to cook (25-30 minutes!). Let me know in the comments if you’d like me to share my steel-cut oats method.

Top Tips For Stovetop Oatmeal
- Make sure to reduce the heat to simmer as soon as it being to boil, otherwise the oatmeal can become very gummy/gluey.
- Adjust the liquid ratio according to your preference. For creamier, thinner oats use the 1 1/4 cup liquid and 1/2 cup oats, for thicker then use 1 cup liquid only. I suggest using 1 cup to begin and thinning it at the last minute of cooking if preferred.
- Don’t omit the salt – it really enhances the flavor, and you only need a pinch!
- For even quicker oatmeal, you can leave the oats and liquid in a covered saucepan the night before. Then cook it in the morning. Keep an eye on it though as it will take just a few minutes to be ready.
- If you use quick-cooked (instant) oats, then it will take just 2-3 minutes to cook.
