2 cans San marzano tomatoes, finely crushed(d.o.p certified if possible)(u can use fresh Roma tomatoes if you got em in season, just make sure to stew them first)
2 cups chicken stock
1 small onion, finely diced
2 large cloves garlic, minced (or 3 small cloves)
1 tsp crushed red pepper flakes
Big ass bunch of fresh basil and oregano, finely chopped
Thyme to taste (don't use the ♥♥♥♥♥♥ stems ♥♥♥♥♥♥♥, just the leaves/buds/whatever the ♥♥♥♥ they are)
2 Bay leaves
2 tbsp sugar (or 1/2 large carrot, for sweetness)
2 tbsp butter (more or less depending on your taste) (if you cook chicken or beef with it use the fat from that instead)
1/8 tsp cayenne pepper (more if you would like, but it's just there to add warmth, not make it hot)
Olive oil (for sautéing onion & garlic)
Salt and pepper to taste

Coat the bottom of a sauce pan in olive oil and heat on a medium high temperature. After the oil has sufficiently warmed add minced onions and sauté until fragrant and begin to sweat (approximately 1-2 min, Idk depends on the amount you use). Lower heat to medium and add the Garlic (don't burn that ♥♥♥♥ yo). After onions and garlic become fragrant add red pepper flakes for a bit then stir in the tomatoes and crush them until desired consistency is achieved. (I find San marzano tomatoes make the best sauce, even though they're canned, if ur anal about fresh tomatoes get a bunch of Roma tomatoes and stew them before hand to use as a substitute).

Add chicken stock, bay leaves, cayenne, with a bit of salt and pepper. Don't add too much salt and pepper bc we're gonna reduce the sauce down, and the more you reduce it the more concentrated the flavors get. (don't over season that ♥♥♥♥ early or else ull want to die later). If u want u can add some oregano here too.

Now take your hand off of your ♥♥♥♥ and grab a big ass wooden spoon so you can channel the spirits of every Italian grandma in history like the ♥♥♥♥♥♥♥ sauce avatar. UR gonna have to CONSTANTLY stir this ♥♥♥♥ for like a minimum of two hours or so, maybe three. It's a ♥♥♥♥♥ to do but when you ♥♥♥ after tasting the end result ull be glad u put in the effort. Once the sauce reduces to an actual sauce and not a soup, give it a taste and add sugar, salt, and pepper to your own personal taste. A good way to test the consistency is to dip the spoon ur stirring with in the sauce and running your finger along the back of the saucy part, if it leaves a clean trail ur good.

If your finger is now in the boiling sauce ur a ♥♥♥♥♥♥♥ and should have realized to take the spoon out of the pot first and let it cool before touching it (really dude?!). Once u got the consistency u want chop up that big ass bunch of basil and mix it in the sauce. Fish out the bay leaves and Bam! Ur finally ♥♥♥♥♥♥ done. Lower that heat to low and now u got sauce for whatever the ♥♥♥♥ u want really, I make food, I'm not a cop. Do what you want with it.
