1medium yellow onion , chopped - I like to cut mine in half moons slices but if you prefer you can chop it finely
4largecloves of garlic , chopped finely
900g / about 5 heaping cupsbaby potatoes , regular potatoes are ok too but the waxier varieties are best because they remain firmer. Floury potatoes might fall apart a bit. Cut any larger ones into chunky bite sized pieces. No need to peel them unless you prefer to.
2tablespoonscurry powder or curry paste, be sure to use a good flavorful brand
500mls / around 2 cups water
400g / 2 heaping cupsfresh green beans , chopped into bite sized pieces. You can also use frozen beans, no need to defrost first. Frozen peas also work well as a sub.
INSTANT POT INSTRUCTIONS (My Instant Pot is a 6 quart. If yours is a different size you will need to scale the recipe up or down accordingly).
Set your instant pot to saute. Once hot, add a few drops of water (or oil) and cook the onions until translucent, then add the garlic and cook for one minute longer. Press the KEEP WARM/CANCEL button.(This sautéing step adds a little more flavour but you can skip it if you are short on time.)
Add everything else to the Instant Pot except the green beans and arrowroot/cornstarch.
Set the Instant Pot to 20 minutes on MANUAL high pressure and allow the pressure to release naturally after this time.
Press KEEP WARM/CANCEL, remove the lid and press SAUTE. Put the arrowroot/cornstarch into a small bowl or cup and mix into it a few tablespoons of water to make a thickish but pourable slurry. Pour it into the Instant Pot stirring as you go.
Add salt and pepper to taste then add the green beans and cook for about 5 minutes until they are tender and the gravy has thickened.
If you don't have an Instant Pot you can cook it on the stove top instead. See these instructions.Cooking time includes the natural pressure release time but this can vary a bit each time so allow for it taking a few minutes more or less.If you like bit of heat in your curry feel free to add some chili flakes or a fresh chopped chili when you add the other vegetables.Leftovers reheat well and will keep in the fridge for up to 4 days.
