Recipe FAQs

How do I know when the pork tenderloin is fully cooked?

Use a meat thermometer to ensure the internal temperature reaches 145°F (63°C) for safe consumption while keeping the pork juicy.

Can I substitute other vegetables for the ones listed?

Yes, root vegetables like potatoes or sweet potatoes can be added to enhance heartiness, or you can choose seasonal vegetables you prefer.

What can I use instead of fresh herbs if I don't have them?

Dried rosemary and thyme work well in the marinade; use about one-third of the fresh herb quantity to maintain balance.

How should I prepare the garlic for this dish?

Mince the garlic finely to allow its aroma and flavor to infuse the pork and vegetables evenly during roasting.

What is a good beverage pairing for this meal?

A dry white wine such as Sauvignon Blanc complements the garlic and herb flavors and balances the dish's richness.
