1 pound macaroni pasta
4 cups water
4 tablespoons butter
1 teaspoon kosher salt
1 teaspoon ground mustard
1/2 teaspoon garlic salt (optional)
1 (5 ounce) can evaporated milk
4 cups shredded sharp Cheddar cheese
2 cups shredded cheese that melts well (Swiss, Gouda, Fontina or Monterey Jack)
To the Instant Pot, add the macaroni, water, butter, kosher salt, ground mustard and garlic salt. Cook in the pressure cooker for 5 minutes on high, then quick release. Add the evaporated milk and half of the cheeses and use a wooden spoon to vigorously stir until the cheeses have melted. Add the rest of the cheese, stirring until the sauce is creamy. Add any additional toppings or mix-ins below at this time.
Note: The creamy texture comes from the evaporated milk and the Swiss-like cheese. Using regular milk and only Cheddar will not yield the same results.
Pesto Mac & Cheese: To each single serving, add pesto sauce (about one tablespoon?), some toasted pine nuts plus chopped sun-dried tomatoes or roasted red bell peppers.
Veggie & Crispy Fried Sage: To the instant pot, stir in cooked butternut squash, steamed broccoli or roasted cauliflower. To make the crispy fried sage, add 1-2 tablespoons of olive oil to a fry pan over medium-high heat. When hot, add the sage leaves and cook for 15-30 seconds, flip, and cook for another 20 seconds or so. Transfer to a paper-towel lined plate and sprinkle with kosher salt to top the mac and cheese.
