Cook your pasta noodles according to the directions on the package. Make sure to reserve 1-2 cups of pasta water to add to the sauce.
Heat your olive oil and butter in a large pot over low/medium heat. Add the garlic, red pepper flakes, and salt. Cook for 1-2 minutes, making sure the garlic doesn't burn.
Add the tomato paste and cook for 4-5 minutes to caramelize the tomato paste.
Add the vodka and cook for 2-3 minutes to burn off the alcohol.
Stir in the pumpkin puree, heavy cream, and honey until it's completely combined.
Add the nutmeg, sage, thyme, and bay leaves.
Stir in the pasta water about ½ cup at a time until it's smooth and glossy. I usually end up adding 1 ½ - 2 cups but it's all personal preference. I still keep whatever pasta water I have remaining in case I need to add more if it dries out while it's sitting.
Add the pasta noodles and combine.
