Recipe Guide

How do I ensure the pork stays juicy?

Rub the tenderloin thoroughly with the garlic and herb mixture and avoid overcooking; resting the meat after roasting also helps retain juices.

Can I substitute the vegetables used?

Yes, you can use root vegetables like potatoes or sweet potatoes for extra heartiness or other seasonal vegetables to suit your taste.

What is the ideal internal temperature for the pork?

Cook the pork tenderloin until it reaches 145°F (63°C) internally, ensuring it is safe and tender.

Is it important to let the pork rest after roasting?

Yes, resting the pork for about 5 minutes allows the juices to redistribute, resulting in a more flavorful and tender bite.

Can I prepare this dish ahead of time?

Marinating the pork ahead enhances flavor, and the assembled tray can be refrigerated before roasting, but cook it fresh for best results.
