Heat butter and olive oil in a large pot over medium heat.
Add minced garlic and sauté for about 30 seconds until fragrant.
Pour in chicken broth and heavy cream and bring to a gentle simmer.
Add uncooked pasta to the pot and stir to submerge it in the liquid.
Cook pasta while stirring occasionally until tender and the sauce begins to thicken.
Stir in grated Parmesan cheese and Italian seasoning until melted and creamy.
Season with salt, black pepper, and red pepper flakes if desired.
Continue stirring until the sauce coats the pasta evenly.
Remove from heat and garnish with chopped parsley.
Serve warm while creamy and delicious.
