Step 1: Cook the Pasta
First, bring a large pot of salted water to a rolling boil. Add your 12 ounces of pasta and cook according to the package instructions until it is perfectly al dente. Drain the pasta and set it aside while you prepare the sauce.

Step 2: Brown the Meat
In a large, heavy-bottomed skillet, cook the 1 pound of ground meat over medium heat. Break up the meat with a spoon as it cooks until it is fully browned through. Once cooked, be sure to drain off any excess grease from the skillet before moving to the next step.

Step 3: Add the Sauce Ingredients
Reduce the heat slightly and stir in the 10 ounce can of Rotel diced tomatoes and green chilies (undrained), 1 cup of heavy cream, 1 teaspoon of taco seasoning, 1/2 teaspoon of garlic powder, and season with salt and pepper to taste. Bring the mixture to a gentle simmer and let it cook for 5 minutes, allowing the flavors to meld and deepen.

Step 4: Combine Pasta and Sauce
Add the previously cooked and drained pasta directly into the skillet with the simmering sauce. Toss everything gently to ensure the pasta is fully coated. Finally, stir in the 1 cup of shredded cheddar cheese until it has completely melted and the sauce is wonderfully creamy and smooth.

Step 5: Garnish and Serve
Top the finished Rotel Pasta Fiesta with fresh cilantro or parsley, if desired, and serve immediately while hot.
