Get a pot of water boiling, heavily salt and add in spaghetti (this will only be cooking for ~3 min here so try to work quickly).
Heat up a separate pot/large pan over medium and add a good glug of olive oil. Add garlic slices for 2 minutes, red pepper flakes, optional fresh oregano and then add in your red wine.
Once wine has come to a bubble, let simmer, then transfer your very al dente spaghetti directly from the pot over to your red wine pan.
Continually stirring, let your spaghetti finish cooking in this sauce until perfectly al dente and the sauce has reduced and the alcohol has cooked out.
Option to finish with a knob of butter and a touch of pasta water to really help it all come together.
Garnish with pecorino and parsley or oregano.
