Instructions
- Wash, peel and thinly slice sweet potatoes. Place them in a large bowl and add salt, pepper and dried garlic. Mix until the slices are coated in seasoning.
- To make the creamy sauce: heat the oil in a small-medium sauce pan. Add flour and whisk until well combined. Cook for about a minute. Now add the cream while constantly stirring. Bring this to a boil (while stirring) and turn off the heat. Stir in grated cheese and butter (optional).
- Cover the bottom of your springform pan with 2-3 layers of sweet potato slices, spread about 3 tablespoons white sauce over. Continue until you have used up all your sweet potato slices and white sauce. Finally top with a generous amount of grated cheese.
- Cover the pan with tin foil. Place steam rack (with handles) in your instant pot. Add the water and place the pan inside. Cover with lid and lock.
- Turn the steam release to “SEALING”. Press “MANUAL” and set the timer to 30 minutes.
- When the cooking cycle is finished, wait until the steam is released naturally (until the pin drops down). Take the pan out, let it cool down a bit and serve.
Notes
- This recipe was made in a 6 quart/6 liter Instant Pot.
- Springform pan size: 7 inch/18cm wide and 3.5 inch/9cm deep.
- The cooking time does not include time needed for the pot to come to pressure and also time needed to release the pressure.
- If you serve this immediately, the sauce will be runny and cheese nicely melted. However, the gratin will not hold its shape.
- If you want to divide into individual portions and slice it nicely, wait until it’s cooled down.
- This gratin can be made ahead and reheated, if needed.
- If you don’t have a pressure cooker, follow the same instructions but place it in the oven instead of Instant Pot. The baking time will be somewhere between 80-90 minutes.
