How Long to Roast a 5 - Pound Pork Butt Porchetta

Question

I am in the process of making the Fennel-Rosemary Porchetta roast for Sunday dinner.
I have a smaller Boston butt than the one called for in the recipe and am wondering how long it should roast.
The recipe called for a 7-8lb roast but mine is just 5lbs. I was thinking maybe 5-6 hours??
Please advise.
Thanks

Hi Mary - thanks for reaching out! We apologize for the delay in responding to your question and hope that your Sunday dinner came out great. The cook time adjustment here will depend on whether your Boston Butt is small because it has been cut down to size (for example, cut in half cross-wise, also called "split"), or whether it is simply a smaller, but whole, cut of meat. In the former case, the cook time shouldn't need to be adjusted, as the diameter of the pork butt isn't changed. In the latter case, where you have an entire pork butt that happens to be on the small size, you can plan for 1.15 hours per pound of meat. So, you are right that a 5 pound pork butt would require between 5-6 hours in the oven.
We would love to hear how long you ended up roasting yours for and how it came out!
