Ingredients for Cast Iron Pork Loin

Gathering your ingredients is the first step to this simple yet impressive meal. You’ll need a good quality pork loin, about 1 pound. For the perfect cast iron pork loin seasoning, we’ll mix together 1 teaspoon each of garlic powder, salt, dried rosemary, and dried thyme, plus 1/2 teaspoon of cracked black pepper. This blend creates a savory crust that’s simply irresistible. For searing and cooking, we’ll use 2 tablespoons of avocado oil, which has a high smoke point. You’ll also need 4 tablespoons of butter for the sauce, 1 medium shallot (finely minced), 1 tablespoon of apple cider vinegar for a touch of acidity, 2 tablespoons of stone ground mustard for a tangy kick, 1 cup of heavy cream for richness, and 1 cup of chicken stock to form the base of our delicious pan sauce.

How to Make Cast Iron Pork Loin

Ready to master this fantastic dish? Let’s walk through exactly how to cook pork loin in cast iron for that perfect sear and roast.

Step 1: First things first, preheat your oven to a nice, hot 400°F (200°C). This ensures it’s ready to go when your pork is perfectly seared.
Step 2: In a small bowl, combine all your dried herbs and spices. I like to mix my garlic powder, salt, rosemary, thyme, and pepper together until they’re well blended. This is your essential cast iron pork loin seasoning.
Step 3: Take your pork loin and pat it really dry with paper towels. This step is crucial for getting a great sear. Then, coat the entire loin generously with that herb and spice mixture. You want every surface to have that delicious flavor.
Step 4: Place your cast iron skillet over medium heat and add the avocado oil. Once the oil is shimmering – you’ll see it start to ripple slightly – carefully place the seasoned pork loin into the hot skillet. Sear it on all sides for about 2-3 minutes per side. You’re looking for a beautiful, golden-brown crust, which is the start of that amazing cast iron pork loin browning.
Step 5: Now, carefully transfer the entire skillet, pork loin and all, into your preheated oven.
Step 6: Let it roast for approximately 25 minutes. The best way to know it’s done is by using a meat thermometer. You’re aiming for an internal temperature of 150°F (65°C) in the thickest part of the loin.
Step 7: Once it hits that perfect temperature, remove the skillet from the oven. Transfer the pork loin to a clean plate or cutting board and tent it loosely with foil. Let it rest for at least 10 minutes. This resting period is key to a juicy result!
Step 8: While the pork rests, return the cast iron skillet to the stovetop over medium-low heat. Carefully pour out any excess oil, leaving behind the flavorful bits. Melt the butter in the skillet; it smells amazing as it sizzles!
Step 9: Add your finely minced shallots to the melted butter and sauté them until they become nice and translucent, about 2-3 minutes. Then, pour in the apple cider vinegar and let it bubble and cook down for about a minute, scraping up any browned bits from the bottom of the pan.
Step 10: Whisk in the heavy cream, chicken stock, and stone ground mustard. Keep whisking until everything is smooth and well combined.
Step 11: Let the sauce simmer gently for 2-3 minutes, stirring occasionally, until it thickens slightly. It should coat the back of a spoon nicely.
Step 12: Slice your rested pork loin and serve it with that luscious shallot cream sauce drizzled generously over the top. Enjoy your perfectly cooked cast iron pork loin!
