Tips and tricks to make this technique work

Reheating your mac and cheese in a cast iron skillet is a straightforward food hack, but there are a few tips that can enhance the process and elevate the flavor of your dish. First, add a splash of milk to rehydrate your pasta. The cold, dry environment of your refrigerator can sap moisture from your leftovers, so a few tablespoons of milk for each cup of pasta can help restore its texture.
Next, prepare your cast iron skillet to maximize its cooking potential. Start by adding a small amount of oil with a high smoke point, such as vegetable or canola oil, and preheat the pan until the oil begins to shimmer. You want the skillet hot enough to create a delicious cheesy crust on the bottom, but not so hot that it burns the cheese upon contact. Rehydrating the pasta is crucial here, as dry pasta would simply fry and turn into a crunchy mess. The added moisture protects the pasta from burning and helps it regain its creaminess.
Finally, cover your pasta while it reheats to ensure even heat distribution. When left uncovered, the top of the pasta loses heat, which can lead to the bottom scorching before the top warms up. By covering the skillet, you trap heat inside, effectively turning it into a mini oven. This technique guarantees that your mac and cheese comes out bubbling and hot throughout.
