Ingredients
- 1 pork loin (about 1.2–1.5 kg / 2.5–3 lbs)
- 1 packet onion soup mix
- 1 cup water
- 2 tablespoons olive oil
Step-by-Step Method
Step 1: Preheat the Oven
Preheat your oven to 180°C (350°F). This ensures even cooking and helps the pork stay juicy.
Step 2: Prepare the Pork Loin
Pat the pork loin dry with paper towels. This helps the seasoning stick better and promotes a nice outer texture.
Rub the pork loin evenly with olive oil, making sure all sides are lightly coated.
Step 3: Season Generously
Sprinkle the entire packet of onion soup mix over the pork loin.
Massage it gently into the surface so it adheres well. This mix contains dried onions, salt, and spices that will form a flavorful crust as it bakes.
