Ingredients
For the Pork Tenderloin:
- 1–1.5 lb pork tenderloin
- 2 tbsp olive oil
- 3 garlic cloves, minced
- 1 tsp dried rosemary
- 1 tsp dried thyme
- ½ tsp salt
- ½ tsp ground black pepper
- 1 tbsp Dijon mustard
For the Roasted Potatoes:
- 1 lb baby potatoes, halved
- 1 tbsp olive oil
- Salt, pepper, garlic powder (to taste)
- Fresh parsley (optional, for garnish)
Ingredient Notes & Swaps
- Fresh herbs? Go for it! Use triple the amount if subbing fresh for dried.
- No baby potatoes? Yukon Gold or red potatoes cut into chunks work just as well.
- Spice it up: Add a pinch of crushed red pepper flakes or smoked paprika.
- Want it lower carb? Swap the potatoes for chunks of roasted cauliflower or radishes.
Instructions
1. Preheat & Prep
- Preheat oven to 425°F (218°C).
- Line a rimmed baking sheet with parchment paper or foil for easy cleanup.
2. Season the Pork
- In a small bowl, mix the olive oil, garlic, rosemary, thyme, salt, pepper, and Dijon mustard.
- Rub this mixture evenly over the entire pork tenderloin.
3. Prep the Potatoes
- In a separate bowl, toss halved baby potatoes with olive oil, salt, pepper, and garlic powder.
- Spread potatoes around the pork on the sheet pan.
4. Roast
- Roast for 25–30 minutes, or until pork reaches an internal temp of 145°F (63°C) and potatoes are tender and golden.
- Let pork rest for 5–10 minutes before slicing to retain juices.
5. Serve
- Sprinkle with chopped parsley if desired.
- Serve hot with a side salad or steamed green beans.
Tips for Success
- Use a meat thermometer for perfect doneness—145°F ensures the pork stays juicy.
- Let the pork rest before slicing so juices redistribute.
- Slice potatoes evenly for consistent roasting.
- Double the garlic herb mixture and save half to brush on pork after cooking for extra flavor!
