  • ½ teaspoon kosher salt
  • 2 tablespoons salted butter (¼ stick)
  • 1 teaspoon minced garlic

  • Seal the Instant Pot and pressure cook the potatoes for 1 minute. It will take longer than 1 minute for the pot to pressurize but that is ok. Allow it to pressurize and then cook the potatoes for just 1 minute.
  • After the potatoes have cooked for 1 minute, turn off the Instant Pot and quick release the remaining pressure.

  • Grease an 8x8-inch baking pan with nonstick spray and then gently remove the potatoes from the pot and place them in the prepared pan. Try to keep as much liquid in the pot as possible.

  • Serve hot.

Notes

  • Take care to slice the potatoes into even ¼-inch thick slices; use a mandoline or food processor for easy even slices!
  • If your instant pot can't be set for less than 5 minutes, set it for the lowest amount of time available but set a separate timer so that you can turn off the pot and release the steam after 1 minute of cooking.
  • Shred your own cheese from a block for the smoothest sauce. Pre-shredded cheese is coated in starches that can cause the sauce to become grainy!
  • Add the half-and-half slowly to prevent curdling.
  • Watch the potatoes closely as you broil them to avoid burning the cheese.
Storage: Store instant pot scalloped potatoes in an airtight container in the refrigerator for up to 4 days or in the freezer for up to 3 months.
