Bring a large pot of salted water to a boil. Add the ziti noodles and cook until al dente, following the package instructions. Be careful not to overcook, as the pasta will continue baking later. Once cooked, drain the pasta and set aside.
Step 2: Brown the Ground Beef
In a large skillet over medium-high heat, cook the ground beef, breaking it apart as it browns. Continue cooking until there is no pink remaining. Drain any excess grease to keep the dish from becoming too oily.
Step 3: Add Taco Seasoning
Return the cooked beef to the skillet. Add the taco seasoning and 1 cup of water. Stir well so the seasoning fully coats the meat. Let the mixture simmer for about 5 minutes, allowing the flavors to blend and the sauce to thicken slightly.
Step 4: Melt in the Cream Cheese
Add the cream cheese directly into the beef mixture. Stir slowly until the cream cheese melts completely, creating a creamy, cohesive sauce. Once the cream cheese has blended smoothly, remove the skillet from the heat so it doesn’t overcook.
Step 5: Assemble the Pasta
Transfer the cooked ziti to a baking dish. Add 1 cup of grated cheese and toss the pasta gently to distribute the cheese evenly. This creates a cheesy base that melts beautifully during baking.
Spoon the creamy taco beef mixture over the pasta. Toss lightly to blend some of the sauce into the noodles while still leaving visible layers of creamy beef throughout the dish.
Step 6: Add the Final Layer of Cheese
Sprinkle the remaining cheese evenly over the top. This final layer melts into a bubbly, golden topping as the dish bakes.
Step 7: Bake
Bake the assembled dish uncovered at 350°F (175°C) for 15–20 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
