Cook the Pasta: Bring a large pot of salted water to a boil. Add the bowtie pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta water, then drain the pasta and set aside.
Sauté Garlic: In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to burn it.
Make the Creamy Sauce: Reduce the heat to low. Pour in the heavy cream and stir to combine. Gradually add the grated Parmesan cheese, Italian seasoning, salt, and pepper, mixing until the cheese melts and the sauce is smooth.
Combine Pasta and Sauce: Toss the cooked bowtie pasta in the creamy sauce. If the sauce is too thick, gradually add a bit of reserved pasta water until you reach your desired consistency.
Add Spinach and Herbs: Stir in the baby spinach and let it wilt slightly in the sauce. Then fold in the chopped parsley for a fresh flavor.
Season and Serve: Taste and adjust the seasoning with more salt, pepper, or crushed red pepper flakes if desired.
Notes
Add crushed red pepper flakes for extra heat if desired.
