Buttered noodles were the ultimate comfort food growing up, and this version might be even better than the original. It's rich, garlicky, and a little bright from the lemon, with a protein boost that means it can actually hold its own as a full meal instead of just a side dish!
The trick here is cooking the pasta directly in bone broth instead of plain water. It absorbs all that savory depth as it cooks, so by the time you stir in the butter and parmesan, you barely need to season anything else.
