1. Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente (usually about 9-11 minutes). Reserve ½ cup of pasta water before draining.
2. While the pasta cooks, heat a large skillet over medium heat and add 1 tablespoon of olive oil.
3. Add the sausage pieces to the skillet and cook for 6-8 minutes, turning occasionally until nicely browned and cooked through. Remove the sausage from the skillet and set aside.
4. Lower the heat to medium-low and add the butter to the same skillet. Once melted, add the minced garlic and sauté for about 1 minute until fragrant but not browned. This step always reminds me of my early kitchen experiments—garlic is delicate, and getting this right makes all the difference.
5. Pour in the heavy cream and stir to combine, scraping up any browned bits from the sausage for extra flavor. Let the cream gently simmer for 3-4 minutes, allowing it to thicken slightly. Stir frequently to prevent scorching.
6. Gradually whisk in the grated Parmesan cheese until the sauce is smooth and creamy. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it up to your desired consistency.
7. Return the browned sausage bites to the skillet, stirring to coat them evenly with the sauce. Season with salt, pepper, and a pinch of red pepper flakes if using. Cook for another 2 minutes to meld the flavors.
8. Add the drained pasta to the skillet and toss everything together gently over low heat until the pasta is fully coated with the creamy sauce. If needed, add a little more pasta water to keep it saucy.
9. Remove from heat and garnish with chopped fresh parsley if you like. Serve immediately and enjoy the warmth and comfort of this hearty meal.

One tip I’ve learned over years of cooking for my family is to trust your senses. Watch the sauce as it simmers and be ready to adjust the heat or add pasta water. It’s all about balance, which reminds me of that night I spent fixing my oversalted chili—sometimes you just need to tweak as you go, and that’s okay.
