Ingredients

Instructions

  1. Step 1: In a large microwave-safe mug, combine 1/3 cup elbow macaroni and 1/2 cup water. Microwave uncovered on high for 2 minutes, then stir carefully.
  2. Step 2: Continue microwaving in 2-minute increments, stirring after each, until the pasta is tender and water is mostly absorbed, approximately 6-8 minutes total.
  3. Step 3: Carefully add 1/4 cup milk, 1/3 cup shredded sharp cheddar cheese, 1/8 tsp salt, and a pinch of black pepper to the mug.
  4. Step 4: Stir well and microwave for another 30-45 seconds until the cheese melts and the sauce thickens slightly. Stir again and serve warm.
