Ingredients
For the Pork and Potatoes
- 1 (about 3 lb) boneless pork loin roast, tied with butcher's twine
- 2 Tbsp olive oil, divided
- 2 lbs baby potatoes (Yukon gold or red), halved or quartered
- 4 cloves garlic, minced
- 2 Tbsp fresh rosemary, chopped
- 1 Tbsp fresh thyme, chopped
- 1 tsp salt, divided
- 1/2 tsp black pepper, divided
For the Pan Gravy
- 1 Tbsp all-purpose flour
- 1 cup chicken broth
- 1 Tbsp balsamic vinegar (optional, for depth)
- 1 Tbsp butter, cold
Directions
- Prep the Roast: Pat the pork loin roast dry. Rub it all over with 1 tablespoon of olive oil, 1/2 teaspoon of salt, 1/4 teaspoon of pepper, and half of the chopped rosemary and thyme.
- Prep Potatoes: In a large bowl, toss the potatoes with the remaining 1 tablespoon of olive oil, the minced garlic, the remaining rosemary and thyme, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper.
- Sear the Pork (Stovetop): Place your All-Clad D3 Stainless 3-ply Bonded Cookware, Mother of All Pans with lid, 6 quart over medium-high heat. Add a thin layer of cooking oil (or use the oil already on the roast). Sear the pork loin for 2–3 minutes on all sides until a deep golden brown crust forms. Remove the pork and set it aside.
- Assemble for Roasting: Lower the heat slightly. Arrange the seasoned potatoes in a single layer across the bottom of the pan. Nestle the seared pork loin roast into the center of the potatoes.
- Roast (Oven): Transfer the pan to a preheated oven at 400∘F (200∘C). Roast for 45–55 minutes, turning the potatoes once halfway through. The roast is done when a meat thermometer inserted into the thickest part reads 145∘F.
- Rest: Transfer the pork loin to a cutting board, tent it loosely with foil, and let it rest for 10–15 minutes. Leave the potatoes in the pan (or remove them and keep them warm).
- Make the Gravy (Stovetop): Place the pan back on the stovetop over medium heat. Scrape up any caramelized bits (the fond) from the bottom of the pan with a wooden spoon or spatula—this is where the flavor is! Sprinkle the flour into the pan drippings and whisk continuously for 1 minute to form a light roux.
- Thicken and Finish: Slowly whisk in the chicken broth and balsamic vinegar (if using). Bring the mixture to a simmer, whisking occasionally until the gravy thickens slightly, about 3 minutes. Remove the pan from the heat and swirl in the cold butter for richness and shine. Taste and adjust salt and pepper if needed.
- Serve: Slice the pork loin roast and serve immediately with the roasted potatoes, drizzling the fresh pan gravy generously over the top.
