Make your Creamy Parmesan Beef Linguine with Garlic Butter Sauce effortlessly by following these steps:

1. Cook the Linguine: Begin by boiling a large pot of salted water. Add the linguine and cook according to package instructions until al dente. Drain and set aside.
2. Brown the Beef: In a large skillet over medium-high heat, add the ground beef. Brown it until fully cooked, breaking it into smaller pieces as it cooks (about 5-7 minutes). Drain excess grease if necessary.
3. Add Garlic: Once the beef is browned, add the minced garlic to the skillet. Sauté for 1-2 minutes until fragrant but not browned.
4. Incorporate Butter and Cream: Reduce heat to medium and add the unsalted butter. Once melted, pour in the heavy cream, stirring well to combine.
5. Mix in Cheese: Gradually add the grated Parmesan cheese to the skillet, stirring until melted and the sauce is smooth. Season with salt and black pepper to taste.
6. Combine Pasta: Toss the cooked linguine into the sauce, ensuring every strand is well-coated. Heat briefly until warmed through.
7. Serve: Remove from heat, garnish with fresh parsley, and an optional sprinkle of red pepper flakes for added flavor.
