Step 1

Place the potatoes, chicken broth, and salt together in your Instant Pot and stir until the potatoes are all wet.

Step 2

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.

Step 3

After the potatoes have cooked for 1 minute, turn off the Instant Pot and quick release the remaining pressure.

Step 4

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.

Step 5

Add the butter and minced garlic to the liquid in the Instant Pot and set the sauté function for 7 minutes, stirring frequently.

Step 6

After the pot has heated and the butter is bubbling, slowly mix in the half-and-half, stirring constantly.

Step 7

Mix in the italian seasoning and allow the sauce to cook and continue stirring until the sauce has thickened, about 2-3 minutes.

Step 8

Turn off your Instant Pot and stir in 1 cup of marbled cheddar cheese until melted and combined.

Step 9

Pour the sauce over the potatoes and gently spread it evenly over the potatoes.

Step 10

Sprinkle the remaining ½ cup of shredded cheese all over the top.

Step 11

Place the 8x8-inch baking dish in the oven and broil for 5-7 minutes, or until the potatoes are bubbling and golden brown on top.

Step 12

Serve hot.
