  • Total Time: 30 minutes
  • Yield: 6 servings

Ingredients

Potatoes and Stock

  • 2 pounds (900g) white potatoes, peeled and sliced
  • 1 cup (237ml) vegetable stock

Seasonings and Aromatics

  • 2 cloves garlic, minced
  • 2 tbsp thyme, chopped
  • 2 tbsp butter

Dairy and Cheese

  • 1 cup (237ml) heavy cream
  • 9 oz (255g) cheddar cheese, grated

Instructions

  1. Prepare the Potatoes: Peel and thinly slice the white potatoes to ensure even cooking and a creamy texture. Set them aside while you prepare the other ingredients.
  2. Sauté Aromatics: Turn the Instant Pot to sauté mode. Add butter and minced garlic to the pot, cooking until fragrant and lightly golden, about 1-2 minutes. This step enhances the dish with a rich garlic flavor.
  3. Add Potatoes and Herbs: Layer the sliced potatoes into the Instant Pot. Sprinkle the chopped thyme evenly over the potatoes to infuse a fresh herbal aroma.
  4. Pour in Vegetable Stock: Carefully add 1 cup of vegetable stock, ensuring it covers the potatoes partially to prevent burning and promote steaming during pressure cooking.
  5. Pressure Cook: Seal the Instant Pot lid and set it to manual high pressure for 8 minutes. This cooks the potatoes until tender but not mushy.
  6. Quick Release Pressure: Once cooking is complete, perform a quick release of the pressure by carefully turning the valve to vent. Open the lid once the pressure is fully released.
  7. Add Cream and Cheese: Stir in 1 cup of heavy cream and the grated cheddar cheese directly into the potatoes. Mix gently to combine, allowing the cheese to melt and create a creamy sauce.
  8. Warm and Thicken: Set the Instant Pot to sauté again at low heat, and stir continuously for 2-3 minutes until the sauce thickens to your desired consistency without boiling over.
  9. Serve: Once thickened, turn off the Instant Pot and serve the scalloped potatoes hot as a delicious side dish or a comforting vegetarian main.

Notes

  • For extra flavor, sprinkle some freshly ground black pepper or paprika on top before serving.
  • You can substitute heavy cream with half-and-half for a lighter version, but the dish may be less creamy.
  • If you prefer sharper cheese, use aged cheddar or mix with Gruyère for a richer taste.
  • Make sure to slice potatoes evenly to ensure even cooking in the Instant Pot.
  • This recipe is vegetarian but not vegan due to dairy ingredients.
