🥩 Only 4 ingredients—pantry staples!
⏱️ 10 minutes prep, 30–40 minutes roast
💛 One roasting pan = easy cleanup
💸 Costs under $10—feeds 4–6 generously
🌾 Naturally nut-free & gluten-free (use GF soup mix)
Ingredients You’ll Need
1 (2–2.5 lb) boneless pork loin roast
1 (1 oz) packet dry onion soup mix (like Lipton)
2 tbsp olive oil or melted butter
½ cup water or low-sodium chicken broth
Optional: Fresh thyme or rosemary sprigs
💡 Pro Tips:
Pat pork dry before seasoning—ensures a golden crust.
Use full-fat onion soup mix—low-sodium versions work but may need extra seasoning.
Don’t skip the water/broth—it creates steam for tenderness and prevents burning.
Step-by-Step Instructions (Juicy, Golden, Foolproof)
1. Prep & Preheat
Preheat oven to 375°F (190°C).
Pat pork loin dry with paper towels.
2. Season the Pork
In a small bowl, mix onion soup mix and olive oil to form a paste.
Rub evenly over entire surface of pork loin.
3. Roast to Perfection
Place pork in a rimmed baking dish or oven-safe skillet.
Pour water or broth into the bottom of the dish (not over the pork).
Optional: Tuck fresh herb sprigs around the roast.
Roast 30–40 minutes, until internal temperature reaches 145°F (63°C).
For deeper color, broil 2–3 minutes at the end (watch closely!).
4. Rest Before Slicing
Let rest 10 minutes—this locks in juices and ensures tenderness.
Slice into ½-inch medallions; spoon pan juices over top.
