Bring a large pot of salted water to a boil. Cook the pasta according to the package directions until al dente. Reserve about 1/2 cup of pasta water, then drain.

Heat the olive oil in a large skillet over medium heat. Add the beef sausage pieces and cook, turning occasionally, until browned and cooked through. Transfer the sausage to a plate and set aside.

Reduce the heat to medium-low. Add the butter to the same skillet and allow it to melt.

Add the minced garlic and sauté for about 30 seconds, stirring constantly, until fragrant. Avoid letting the garlic brown.

Pour in the heavy cream and stir well, scraping up the flavorful browned bits from the bottom of the skillet.

Let the cream gently simmer for 2–3 minutes. Reduce the heat to low and gradually stir in the Parmesan cheese until melted and smooth.

Season the creamy garlic pasta sauce with salt and black pepper. If the sauce is too thick, stir in a small amount of the reserved pasta water until it reaches your preferred consistency.

Add the cooked pasta and sausage back to the skillet. Toss gently until everything is evenly coated in the sauce.

Let the Garlic Butter Sausage Bites with Creamy Parmesan Pasta warm together for another 1–2 minutes.

Garnish with fresh parsley and serve warm.
