Roast Pork Loin Recipe Ingredient Notes
Here’s what you’ll need to make this easy boneless pork loin roast recipe!
You must try the reader-favorite Slow cooker pork loin, Instant Pot Pork Loin and Air Fryer Pork Loin recipe, too!
- Pork loin: A lean, flavorful cut (different from tenderloin!) that is perfect for roasting.
- Garlic and onion powder: Provides a rich garlic flavor without burning, unlike fresh minced garlic.
- Smoked paprika: Adds a subtle smoky undertone and adds a rich color.
- Kosher salt and black pepper: Good seasoning is key!
- Light olive oil or avocado oil: A high-heat oil that helps the seasoning stick while developing a golden-brown crust.
- Fresh rosemary and thyme: Fresh is best, but dried rosemary and thyme can be used for a more concentrated flavor.
- Chicken broth: Provides moisture during roasting, preventing the pork from drying out.

For the Pan Sauce
- Unsalted butter: Adds richness and helps develop a smooth sauce.
- Onion: Finely minced to dissolve into the sauce, adding depth and sweetness.
- Flour: Thickens the sauce, creating a velvety texture.
- Chicken broth: Acts as the base for the sauce, adding savory depth.
- White wine: It brings acidity and complexity and can be replaced with more broth if preferred.
- Grainy mustard (or Dijon): Adds a tangy, slightly spicy contrast to the creamy sauce.
- Heavy cream: Lends a rich, silky texture, balancing the sharpness of the mustard.
- Soy sauce: Enhances umami and deepens the sauce’s savoriness.
- Pan drippings: The key to an ultra-flavorful sauce incorporating caramelized bits and natural juices (same with my amazing Beef Chuck Roast).
Recipe Substitutions
- Pork loin alternative: Swap with pork tenderloin for a quicker cooking time; adjust roasting time accordingly.
- Garlic: For a stronger flavor, use fresh minced garlic.
- Smoked paprika: Replace with regular or sweet paprika.
- Chicken broth: Vegetable or beef broth works for a different taste.
- White wine: Use apple cider vinegar, lemon juice, or additional broth for an alcohol-free option.
- Grainy mustard: Dijon or spicy brown mustard can be used for a smoother sauce.
- Heavy cream: Substitute with half-and-half or milk whisked with 1 1/2 tsp cornstarch.
- Soy sauce: Omit and add salt to taste
Variations of Pork Loin Roast
- Herb blend: Try sage or oregano instead of rosemary and thyme.
- Spicy kick: Add a pinch of cayenne or red pepper flakes to the seasoning mix.
- Garlic butter glaze: Mix melted butter with minced garlic and brush over the pork before roasting for added richness.
- Balsamic infused sauce: Replace part of the white wine with balsamic vinegar.
- Apple-flavored twist: Use apple cider instead of wine and broth.

How to Make a Roast Pork Loin: An Easy Guide
One of the tricks to making an incredible roast pork loin is to season it beautifully and get a good crust on the outside. Follow my easy step-by-step guide to making perfect roast pork loin:
Sear the pork
Preheat oven to 375°F. Pat pork dry and add the spice rub of garlic powder, onion powder, smoked paprika, salt, and pepper.
Heat oil in a cast iron skillet over medium-high heat until shimmering. Sear pork, smooth side down, for 4 minutes, then flip and sear the other side.
Roast the pork
Rub the seared pork with olive oil, rosemary, and thyme. Pour chicken broth into the roasting pan (not over the pork).
Roast in the oven until the internal temperature reaches 140°F, about 25-35 minutes. Remove, tent with foil, and rest for 15 minutes (temp will rise to 145°F). Skim excess fat from pan drippings.
Make the pan sauce
Melt butter in a saucepan over medium heat. Sauté onion with salt until softened. Whisk in flour and cook until golden.
Slowly whisk in broth and wine, stirring to prevent lumps. Add mustard, cream, black pepper, soy sauce, and pan drippings. Simmer for 3-4 minutes until thickened. Adjust seasoning as needed.
Serve
Slice pork and drizzle with the creamy mustard pan sauce.
5 Common Mistakes When Making Roast Pork Loin
These are some of the key issues I see when roasting pork loin:
- Skipping the searing step: Searing locks in juices and creates a yummy crust. Skipping this step will give you a bland, less-textured roast.
- Not using a meat thermometer: Guessing the doneness can lead to overcooked, dry pork or undercooked, unsafe meat. Always check for an internal temperature of 145°F after resting, according to the USDA.
- Seasoning too lightly: Pork loin is lean and benefits from bold seasoning. Under-seasoning results in a bland roast, so be generous with salt, pepper, and spices.
- Pouring liquid over the pork: Adding broth to the pan is great for moisture, but pouring it directly over the roast washes off the flavorful seasoning. Pour around the pork instead.
- Skipping the resting time: Cutting into the pork too soon causes juices to escape, making it dry. Let it rest for at least 15 minutes to retain moisture and enhance flavor.
Make Ahead and Storage
Rub the pork with spices up to 24 hours ahead and refrigerate for deeper flavor. Let it sit at room temperature for 30 minutes before cooking.
How to store leftovers
Store leftover pork in an airtight container for up to 4 days. Keep the sauce separate for best texture.
Slice the pork and freeze in a sealed bag with some pan drippings for up to 3 months. Freeze the sauce separately.
How to reheat leftovers
Warm pork in a low oven (300°F) covered with foil or gently reheat slices in a skillet with a splash of broth to keep it moist. Reheat sauce over low heat, stirring occasionally.
How to Serve this Roast Pork Loin Recipe
Slice the pork and drizzle the creamy mustard sauce over the top for a rich, flavorful finish.
Serve alongside roasted or au gratin potatoes (gluten-free naturally), crispy eggplant, glazed carrots, mashed cauliflower, buttered green beans, or a green bean casserole.
Turn slices it into sandwiches with thin slices on my no-knead Dutch oven bread, toasted ciabatta or sourdough with arugula and a spread of grainy mustard or aioli.
Spoon extra sauce over fluffy basmati rice, polenta, or creamy mashed potatoes for an indulgent plate.
Pro Tips + Science-Based Secrets
As a registered dietitian and food science expert, I’ve got to share my tips and bits of info with you on this pork roast:
- Room temp before cooking: Let pork sit out for 30 minutes before searing to ensure even cooking.
- Use a meat thermometer: The best way to avoid dry pork is to pull it at 140°F and let it rest until it reaches 145°F.
- Rest for juiciness: Cutting too soon releases all the flavorful juices—wait at least 15 minutes before slicing.
- Thin vs. thick sauce: If the sauce is too thick, add broth; if it is too thin, let it simmer longer.
- Searing locks in flavor, not juices: While searing doesn’t “seal” juices in, it creates the Maillard reaction, enhancing deep, caramelized flavors.
- Resting allows redistribution: When pork rests, juices reabsorb into the muscle fibers instead of spilling out when sliced.
- Acid and fat balance flavor: The white wine and mustard add acidity, cutting through richness, while cream and butter create a velvety mouthfeel.
FAQs About Roast Pork Loin
Just skimming through? Here are some key takeaways from this article:
Pork loin is a larger, wider cut with a fat cap, making it great for roasting. Pork tenderloin is smaller, leaner, and cooks much faster. They are not interchangeable in recipes.
Use a meat thermometer and remove the pork at 140°F, letting it rest until it reaches 145°F. Also, sear it first and cook it with a bit of broth to lock in that moisture.
Yes! This recipe works for both. Bone-in pork loin may take slightly longer to cook but can add extra flavor.
Yes! Sear the pork first, then cook on LOW for 6-8 hours with broth and seasonings for a tender, pull-apart texture.
Yes! Swap the butter for olive oil, the cream for coconut milk, and leave out the butter in the sauce for a dairy-free version.
Resting allows the juices to redistribute, making the pork tender and juicy instead of dry when sliced.

Delicious pork loin- perfectly moist- the pan sauce is outstanding!
This was absolutely delicious. It’s a keeper. The pork was so moist and the sauce was fantastic.
Making it over weekend.
This was fantastic. Meat is juicy paired with good mashed potatoes this is a winner
I made this and was sooo good.
The spice rub burns easily so I had to be careful when searing the roast. After searing, I transferred the pork onto a foil line cookie sheet to finish cooking, with tented foil on top to keep it from getting too dark in the oven. I served the roast with mashed potatoes and green beans. The Dijon mustard sauce is resturant quality and would go well with any meat. I used sherry instead of wine because thats what I had. Everyone loved it. This one is a keeper.
Best loin I have ever made! These cuts are so easy to screw up. Thanks for this.
Made this tonite exactly as written and all I can say is AMAZING!!! Will definitely make again.
Rich and delicious! Roast turns out super juicy and perfectly seasoned. Love this with roasted new potatoes and broccoli. The Husband loved it!
Tip: I had a 4 lb roast and had plenty of seasoning and sauce, so no need to increase for a 4 lb. roast. I ended up needing about 1.25 hours to cook, just for planning purposes.
I just made this pork loin roast and it was delicious. Juiciest pork roast.I’ve eaten in a long time. The last time I made one i didn’t use your recipe and it was terribly dry. I am definitely saving this recipe to use again. I followed your recipe exactly. Except I did not make the sauce because I am eating low carb and I avoid flour. The park roast was so juicy.I didn’t need any sauce for it. Highly recommend.
