Roast Pork Loin Recipe Ingredients
For the Roast
Pork Loin (3 lb) This main star provides a juicy and flavorful basis for your roast, essential for creating that tender result.
Garlic Powder (2 tsp) Offers a robust flavor without the risk of burning; avoid using fresh garlic as a substitute for this recipe.
Onion Powder (2 tsp) Adds depth to the seasoning blend, enhancing the overall taste.
Smoked Paprika (½ tsp) Infuses a subtle smokiness to your roast, elevating its flavor profile.
Kosher Salt (2¼ tsp) A vital seasoning that can be adjusted to suit your taste preferences.
Black Pepper (½ tsp) Adds a hint of spice; aim for about 40 cracks of a pepper mill for the right amount.
Olive Oil (2 tbsp + 1 tbsp) Used for searing the meat and added flavor; you can substitute with light olive or avocado oil.
Fresh Rosemary (1 tbsp) Enhances the roast’s flavors with its aromatic essence; dried can work, too.
Fresh Thyme (1 tbsp) Complements the rosemary beautifully; opt for fresh or 1 tsp dried.
Chicken Broth (1 cup) Keeps your roast moist while cooking; vegetable broth can be a great non-meat option.
For the Creamy Mustard Sauce
Unsalted Butter (4 tbsp) Provides richness to the sauce; olive oil can be swapped for a dairy-free alternative.
Onion (¾ cup, finely minced) Sweetens the sauce as it sautés, forming a flavorful base.
Flour (3 tbsp) Thickens your sauce perfectly; gluten-free folks can opt for cornstarch instead.
White Wine (2 tbsp) Adds a touch of acidity and depth; more broth can replace it if desired.
Grainy Mustard (1 tbsp) or Dijon Infuses a delightful tanginess into the sauce that pairs wonderfully with the pork.
Heavy Cream (½ cup) Gives the sauce its creamy richness; for a lighter option, use half-and-half or coconut milk.
Soy Sauce (1 tbsp) Boosts the umami flavor in the sauce, adding another layer of depth.
How to Make Roast Pork Loin
Prep Pork: Preheat your oven to 375°F. Once ready, pat the pork loin dry with paper towels. In a bowl, combine garlic powder, onion powder, smoked paprika, kosher salt, and black pepper; rub this mixture generously over the entire pork.
Sear Meat: In a cast iron skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering. Carefully add the pork and sear for 4 minutes on one side, then flip and sear for another 4 minutes to lock in those mouthwatering juices.
Season and Roast: Coat the pork with an additional tablespoon of olive oil, then sprinkle fresh rosemary and thyme evenly on top. Pour the chicken broth into the skillet around the pork. Roast in the oven until the internal temperature reaches 140°F, which should take about 25-35 minutes. Once done, tent the pork with foil and let it rest for 15 minutes to allow the juices to redistribute.
Make Sauce: In a saucepan, melt 4 tablespoons of unsalted butter over medium heat. Add the finely minced onion and sauté until soft and translucent. Whisk in the flour, then slowly pour in chicken broth and white wine, stirring continuously to avoid lumps. Add grainy mustard, heavy cream, soy sauce, and any reserved pan drippings, then let it simmer for 3-4 minutes until thickened.
Serve: Slice the rested pork loin and drizzle that creamy mustard sauce generously over each serving.
Optional: Garnish with fresh herbs for an elegant touch.

Roast Pork Loin Recipe FAQs
What type of pork loin should I use for this recipe?
When choosing a pork loin, go for a boneless 3 lb cut. This provides even cooking and ensures tenderness. Avoid tenderloin as it has a different texture and won’t yield the same results.
How should I store leftovers from the roast pork loin?
Store any leftovers in an airtight container in the fridge for up to 4 days. Allow the pork to cool completely before sealing to keep it juicy. If you are planning to enjoy them later, I recommend slicing the pork and freezing it with pan drippings in a freezer-safe container. It will stay delicious for up to 3 months.
Can I freeze roast pork loin, and how do I do it?
Absolutely! For optimal flavor retention, slice the roast pork loin and pack it together with any remaining pan drippings in a freezer-safe container. Ensure that it’s sealed tightly to prevent freezer burn. When you’re ready to enjoy it, thaw overnight in the fridge and then reheat at 350°F until warmed through, ideally covered with foil to keep moisture locked in.
What can I do if my pork loin turns out dry or overcooked?
If your pork loin is dry, don’t fret! You can create a quick sauce using a splash of chicken broth to revive juiciness. Simply heat the broth, add some butter, and whisk it until combined. Serve it generously over the pork slices for added flavor. To avoid this in the future, always use a meat thermometer and aim for that perfect 140°F internal temperature.
Can I customize the recipe for dietary preferences?
Yes, this roast pork loin recipe is quite versatile! For a gluten-free sauce, replace the flour with cornstarch mixed with a bit of cold water. If you re looking for a dairy-free option, swap the unsalted butter with olive oil and use coconut milk instead of heavy cream. Moreover, you can substitute the chicken broth with vegetable broth for a vegetarian-friendly version, while still keeping the flavors delightful!
Is this roast pork loin recipe safe for pets?
While plain cooked pork is typically safe for dogs in small amounts, be cautious with seasonings and sauces as they can be harmful. It s best to refrain from sharing this dish with your furry friends due to the added ingredients like onion and garlic, which can be toxic to pets.
