Creating Beef and Garlic Butter Pasta is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside.
2. Brown the Beef: In a large skillet over medium heat, add the ground beef. Cook until browned and cooked through, breaking it up with a spoon as it cooks. Season with salt and pepper. Drain excess fat if necessary.
3. Add Garlic Butter: In the same skillet, push the beef to one side and add the butter. Once melted, add the minced garlic and red pepper flakes. Sauté for about 1-2 minutes until fragrant.
4. Combine Ingredients: Add the cooked pasta to the skillet with the beef and garlic butter. Toss everything together until well combined, ensuring the pasta is coated with the garlic butter.
5. Incorporate Cheese: Sprinkle the grated Parmesan cheese over the pasta and toss until melted and evenly distributed.
6. Adjust Seasoning: Taste and adjust seasoning with more salt, pepper, or red pepper flakes, if desired.
7. Garnish: Remove from heat and garnish with chopped parsley and lemon zest, if using.
8. Serve: Transfer to serving plates and enjoy your delicious Beef and Garlic Butter Pasta!
