Ingredients
- 1 (2–2.5 lb) boneless pork loin
- 1 packet dry onion soup mix
- 2 tbsp olive oil or melted butter
- ½ cup water or low-sodium chicken broth
- Optional: Fresh thyme or rosemary
Helpful Tips
- Dry the pork before seasoning to help create a golden crust.
- Regular onion soup mix gives the richest flavor; adjust seasoning if using low-sodium.
- Adding liquid to the pan keeps the meat juicy and prevents burning.
Instructions
1. Preheat & Prep
Preheat your oven to 375°F (190°C). Pat the pork loin dry with paper towels.
2. Season
Mix the onion soup mix with olive oil to form a paste. Rub it evenly over the pork.
3. Roast
Place the pork in a baking dish or oven-safe pan. Pour the water or broth into the bottom of the dish (not over the meat).
Add herbs if using. Roast for 30–40 minutes, until the internal temperature reaches 145°F (63°C).
For a deeper golden finish, broil for 2–3 minutes at the end.
4. Rest & Serve
Let the pork rest for 10 minutes before slicing. Cut into medallions and spoon the pan juices over the top.
