A friend's mother made me porridge for breakfast in her kitchen in Kingston about ten years ago.
Not oatmeal. Porridge.
She handed me a bowl of something smooth and pale orange with nutmeg grated over the top, and I ate the whole thing without saying a word.
There were no flakes in it, no lumps, nothing to chew at all.
Just warm, spiced, spoonable and slightly sweet.
She told me sweet potato was one of about six things her family made porridge from, alongside cornmeal, green banana and hominy corn.
I've been making a version of it ever since, usually on cold mornings when I want something that feels like it was made for me.
The pot takes forty minutes and most of that is the sweet potato quietly falling apart in coconut milk.
Here's the part worth knowing before you start.
This is not oatmeal with sweet potato stirred through it.
The oats get ground to a powder and disappear completely, so what you end up with is smooth and loose, without a single oat flake left to bite.
It's served hot, straight from the pot, and it settles flat in the bowl instead of holding a peak.
Give it one cold morning and it'll be in your rotation for good!
What Sweet Potato Porridge Actually Is
Porridge in the Caribbean is a whole category, not a single recipe. The base changes with what's around: cornmeal, green banana, plantain, hominy, peanut, and sweet potato.
The method stays the same across all of them.
You cook a starchy thing down in spiced milk until it thickens the pot itself.
No thickener, no cornstarch, nothing added at the end to make it hold together.
Sweet potato is a ground provision, which is the Jamaican word for the root vegetables that get boiled and served alongside almost everything.
Using one for breakfast isn't a modern health trick.
It's been breakfast for a very long time.
Porridge, Not Oatmeal
One choice decides which of these two dishes you end up with, and it happens in the first minute. Do the oats stay whole, or do they get ground?
Whole rolled oats stay chewy and visible, and what you've made is oatmeal with sweet potato in it.
Ground oats dissolve into the milk and vanish, and what you've made is porridge.
I blitz mine in a spice grinder for about fifteen seconds until it looks like coarse flour.
- The finished texture. Completely smooth, with nothing to chew.
- The consistency. Loose enough to pour off a ladle in a thick ribbon, and it settles level in the bowl.
- The temperature. HOT. This is a stovetop breakfast eaten right away, not something you chill.
- The spoon. A spoon moves through it with no resistance, because there is nothing solid left in the pot.
Want it a little more rustic? Grind half the oats and leave half whole. It's a nice middle ground.
Ingredients You Need
- Sweet potato (1 pound). Peeled and cut into 1 inch cubes so they cook down fast and evenly.
- Full fat coconut milk (one 13.5 oz can). Not the carton drink. The canned stuff is what makes this taste Caribbean instead of generic.
- Whole milk (1 ½ cups). Coconut milk alone is too heavy for a breakfast bowl.
- Rolled oats (⅓ cup). Ground to a coarse flour. This is the thickener.
- Nutmeg (1 teaspoon). Grated fresh from a whole nutmeg. This is the flavor everybody remembers and the pre-ground jar does not come close.
- Cinnamon (1 teaspoon) and ginger (¼ teaspoon). Warmth underneath the nutmeg.
- Vanilla (1 teaspoon). Stirred in at the end.
- Salt (¼ teaspoon). Small amount, big job.
- Sweetened condensed milk (⅓ cup). The traditional finish, and it does something plain sugar can't. It sweetens and enriches at the same time.
- Butter (1 tablespoon). Not traditional and I use it anyway. It gives the finished pot gloss and body.
How to Make It
Step 1: Simmer the Sweet Potato in the Milk
Put the cubed sweet potato, the coconut milk, the whole milk, the nutmeg, cinnamon, ginger and salt in a heavy saucepan.
Bring it to a gentle simmer and cook 18 to 20 minutes over low heat, stirring every few minutes, until a cube falls apart against the side of the pot.
Cooking it in the milk instead of water means nothing gets poured away.
Step 2: Add the Ground Oats
Sprinkle the ground oats in while stirring, and cook another 6 to 8 minutes.
It will thicken noticeably in the last two minutes.
Step 3: Smooth It Out
Either blitz it with an immersion blender for 20 seconds, or mash the cubes hard against the side of the pot with a wooden spoon and stir until it comes together.
The blender gives you glass smooth, the spoon leaves a bit of character.
Step 4: Sweeten and Finish
Off the heat, stir in the condensed milk, the vanilla and the butter.
Pro tip: sweetener goes in at the END. Sugar added early sits on the bottom of the pot and scorches while you're not looking.
Getting the Consistency Right
Here's the test: lift a spoonful and let it fall back. It should drop in a thick unbroken ribbon and sink back into the surface within a second or two.
- Too thick? Whole milk, a splash at a time, over low heat.
- Too thin? Another two minutes of simmering, uncovered.
- Gluey? That's over blending. Twenty seconds with the immersion blender is plenty, past that the starch goes stretchy and unpleasant.
- Remember it sets. It thickens considerably in the two minutes between the pot and the table, so pull it looser than you want it.
How to Serve It
Hot, in a deep bowl, within a couple of minutes of it coming off the heat. This is not a dish that waits around.
I pour a thread of extra condensed milk over the top and let it sink in.
- Toasted coconut flakes. A small handful, for texture against all that smoothness.
- Sliced banana. Traditional and good.
- A little more grated nutmeg. Always.
- A spoon of thick yogurt. Not traditional at all, but the tang works.
Notes and Tips
- Grate the nutmeg fresh. If you buy one whole nutmeg for one recipe this year, make it this one.
- Watch the pot bottom. Milk and starch will catch. Low heat and a stir every few minutes.
- Use a heavy pan. A thin pan scorches the milk before the potato is anywhere near soft.
- Taste before you sweeten. Sweet potatoes vary a lot and the condensed milk is easy to overdo.
- Doubling works. Add about five minutes to the simmer.
Storage and Reheating
- Fridge. Three days in a sealed container.
- It sets solid. Cold, it goes firm enough to slice, which is completely normal.
- Reheating. Low heat, a good splash of milk, and a whisk. It comes back perfectly.
- Freezing. Works for a month, though the texture is slightly grainier after thawing.
Sound old fashioned? It is, and that's exactly why it's good.
Recipe
Sweet Potato Porridge
Ingredients
For the Porridge
- 1 lb sweet potatoes peeled and cut into 1 inch cubes
- 13.5 oz canned full fat coconut milk
- 1 ½ cups whole milk
- ⅓ cup rolled oats ground to a coarse flour
- 1 teaspoon nutmeg freshly grated
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground ginger
- ¼ teaspoon fine salt
To Finish
- ⅓ cup sweetened condensed milk plus more to serve
- 1 teaspoon vanilla extract
- 1 tablespoon butter
- 2 tablespoon toasted coconut flakes optional, to serve
Instructions
Simmer
- Grind the rolled oats in a spice grinder or blender for about 15 seconds until they look like coarse flour. Set aside.
- Put the cubed sweet potato, coconut milk, whole milk, nutmeg, cinnamon, ginger and salt in a heavy saucepan. Bring to a gentle simmer over low heat.
- Cook 18 to 20 minutes, stirring every few minutes and scraping the bottom, until a cube collapses easily against the side of the pot.
Thicken and Finish
- Sprinkle in the ground oats while stirring and cook another 6 to 8 minutes. The pot will thicken noticeably in the last two minutes.
- Blend with an immersion blender for about 20 seconds until completely smooth, or mash the cubes hard against the side of the pot and stir until it comes together. Do not over blend or it turns gluey.
- Off the heat, stir in the sweetened condensed milk, vanilla and butter. Taste and add more condensed milk if your sweet potatoes were mild.
- Serve hot in deep bowls, loose enough to settle level. Add a thread of condensed milk, toasted coconut and more grated nutmeg on top.
Notes
- Ground oats, not whole: ground oats dissolve and give you porridge. Whole rolled oats stay chewy and give you oatmeal with sweet potato in it.
- Fresh nutmeg: grate it from a whole nutmeg. Pre-ground is not close.
- Sweeten off the heat: condensed milk added early scorches on the bottom of the pot.
- The ribbon test: a spoonful should fall back in a thick unbroken ribbon and sink into the surface within a second or two.
- It sets as it stands: pull it looser than you want it, it thickens between the pot and the table.
- Reheating: it goes firm in the fridge. Reheat low with a splash of milk and a whisk.
