Mince the garlic very finely.
In a large skillet over low heat, melt the butter until it foams.
Add the garlic to the butter along with the salt and pepper and cook on a simmer or low for about 5 minutes. You don't want to brown the garlic.
Toss the cooked pasta in with the butter and garlic sauce until all the pasta strands are coated with the sauce.
Sprinkle over fresh parmesan, chopped parsley and crushed red pepper if using. Eat immediately and enjoy!
