Cook the pasta in a large pot of salted water until it is just under al dente. Reserve 1 cup of the starchy pasta water before draining.
1 pound cavatappi or cellentani pasta
In a large, deep skillet or Dutch oven, heat the olive oil over medium-high heat. Add the ground meat and cook until browned and crumbled. Drain any excess grease.
1 pound lean ground beef, 1 tablespoon olive oil
Add the diced onion to the meat and sauté for 3 to 4 minutes until translucent. Stir in the garlic, smoked paprika, and oregano. Cook for 1 minute until fragrant.
½ yellow onion, 3 cloves garlic, 1 teaspoon smoked paprika, 1 teaspoon dried oregano
Pour in the entire can of Rotel, including the juices. Scrape the bottom of the pan to release any browned bits. Let this simmer for 2 minutes to reduce slightly.
10 oz can of RoTel Original Diced Tomatoes and Green Chilies
Reduce the heat to low. Stir in the cubed cream cheese until it is completely melted and smooth. Pour in the heavy cream and half of the reserved pasta water.
4 ounces full-fat cream cheese, ½ cup heavy cream, ½ cup reserved pasta water
Add the undercooked pasta directly into the skillet. Sprinkle the shredded cheddar over the top. Toss continuously with tongs or a sturdy spoon. As the cheese melts, the pasta water and cream will create a thick, glossy sauce. If it is too thick, add more pasta water a tablespoon at a time.
2 cups sharp yellow cheddar cheese
Once the sauce is hugging the noodles and the cheese is fully melted, remove from the heat. Garnish with fresh herbs and a crack of black pepper.
Fresh cilantro or parsley for garnish
