Make deliciously creamy homemade mac and cheese using your instant pot for quick and easy comfort food. This mac and cheese is so decadent and makes a delicious side dish or a meatless meal the entire family will love!
Add the macaroni, butter, water, and salt to the liner of an instant pot.
16 oz Macaroni Noodles, 4 tablespoon Butter, 4 cups Water, 1 teaspoon Salt
Place the lid on the instant pot and set the valve to "sealing" Cook on high pressure for 4 minutes, then perform a quick pressure release to prevent the pasta from overcooking. For most models, press the manual button, then use the + or - buttons to adjust the time for 4 minutes. When the cooking time is complete, to quick release the pressure simply turn the sealing valve to "venting."
Once the pin drops, remove the lid and add the evaporated milk, ground mustard, cayenne, black pepper, the shredded cheeses, and the sour cream. Stir until the cheeses have melted and everything is well combined.
1 cup Evaporated Milk, ¼ teaspoon Ground Mustard, pinch Ground Cayenne, ½ teaspoon Black Pepper, 8 oz Colby Jack Cheese, 8 oz Gruyere Cheese, ½ cup Sour Cream
