Step 1

Turn an Instant Pot onto the “sauté” setting. Add butter, salt, pepper, and 1 tablespoon of the thyme; cook until starting to foam, about 2 minutes. Add sliced potatoes in an even layer, and cook until browned on both sides, about 5 minutes per side (the butter will start to brown). Remove potatoes from Instant Pot, and set aside.

Step 2

Add garlic to the Instant Pot. Place the grate insert (or a trivet or steamer basket) inside Instant Pot. Lay potatoes on grate, and pour chicken stock over potatoes. Cover Instant Pot, and set to 1 minute on High pressure, making sure steaming valve is closed (this will take about 10 minutes to come up to pressure). When done, carefully open steaming valve, and allow steam to fully escape from Instant Pot, about 2 minutes. Remove grate and potatoes from pot, and set aside, leaving liquid in pot.

Step 3

Return Instant Pot to “sauté” setting, and cook butter and chicken stock until slightly reduced, about 2 minutes; remove garlic. Add potatoes back to pot in a single layer, and cook again until browned on both sides, about 3 minutes per side. Remove from Instant Pot, and sprinkle with flaky sea salt and remaining thyme. Serve immediately.
