Recipe FAQ

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

Use a meat thermometer to check the internal temperature. It should reach 145°F (63°C) for safe consumption.

Can I substitute the pork tenderloin with another protein?

Yes, chicken breast can be used instead but adjust the cooking time to ensure it cooks through without drying out.

What vegetables work best for roasting with pork?

Root vegetables like carrots and starchy vegetables like bell peppers, zucchini, and onions roast well and complement the pork’s flavors.

Is it important to let the pork rest after roasting?

Resting allows the juices to redistribute, resulting in a moist and tender texture when sliced.

Can I prepare the dish ahead of time?

You can marinate the pork and chop the vegetables ahead, then roast just before serving for best freshness.
