Begin by bringing a large pot of salted water to a boil. Add the 8 oz of fettuccine to the boiling water and cook according to the package instructions until al dente. Once cooked, drain the pasta in a colander and set aside.
In a large skillet, melt the ½ cup of unsalted butter over medium heat. Once melted, add the 4 minced garlic cloves and sauté for about 1 minute until fragrant.
Add 1 tsp of salt, ½ tsp of black pepper, and 1 tsp of Worcestershire sauce to the skillet. Stir well to combine, allowing the flavors to meld together.
Add the 4 oz of cubed cream cheese to the skillet. Stir continuously until the cream cheese is melted and fully combined with the butter and garlic mixture.
Pour in the ½ cup of heavy cream and continue to stir until the mixture is smooth. Gradually add the 1 cup of shredded cheddar cheese, stirring constantly until the cheese is melted and the sauce is creamy.
Remove the skillet from heat and stir in the ½ cup of sour cream and ½ tsp of smoked paprika. Mix until fully incorporated.
Add the drained fettuccine back into the skillet with the creamy sauce. Toss gently to ensure each strand of pasta is coated in the luscious sauce.
Spoon the Noodles Romanoff onto plates or into bowls. You can garnish with additional cheddar cheese or a sprinkle of smoked paprika for an extra touch. Serve warm and enjoy the comforting flavors!
