1
Thinly slice a whole red onion and add to a pot with some butter.
2
Caramelize the onions by letting them start to burn, then deglaze with a little water to lift up all that flavor.
3
Repeat the process until the onions look like this.
4
Add some hot Italian sausage, garlic, beef broth, and your dry pasta.
5
Once that's nicely cooked, add heavy cream, fresh parm, and your chili oil.
