Instructions

  1. Step 1: In a large saucepan, combine 8 oz uncooked penne pasta, 1 1/2 cups whole milk, 1 cup marinara sauce, and 1 cup water. Stir gently until ingredients are evenly distributed.
  2. Step 2: Place the saucepan over medium heat and bring the mixture to a gentle simmer, stirring occasionally to prevent sticking. Cook uncovered for 12-15 minutes until the pasta is tender and most of the liquid is absorbed.
  3. Step 3: Remove the saucepan from heat and stir in 1 cup shredded mozzarella cheese, 1 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper until the cheese melts and the sauce becomes creamy and coats the pasta evenly.
