Roast Pork Loin With Creamy Dijon Sauce

My grandmother, bless her heart, wasn’t much of a risk-taker in the kitchen. Sunday dinners were always a predictable rotation of pot roast, baked chicken, and, if we were lucky, her famous pork loin. But it wasn’t just any pork loin. She had this incredible knack for creating the most luscious, creamy sauce, spiked with just the right amount of Dijon mustard. Every time I taste this dish, I’m instantly transported back to her cozy kitchen, the scent of roasted pork filling the air, and her gentle hands carefully carving each slice. It’s a memory, a feeling, and a flavor I cherish, and it’s what inspires me to share this adaptation of her recipe with you today.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 40 minutes
• Total Time: 55 minutes
• Servings: 4
• Yield: 4 servings
• Dietary Type: Gluten-Free (check wine label)

Ingredients

• 2 tablespoons olive oil
• 1 tablespoon butter
• 2 ½ lbs boneless pork loin roast, net removed and retied with kitchen string
• 1 medium onion, chopped
• ¾ cup white wine
• 2 tablespoons Dijon mustard
• ½ cup sour cream
• 1 tablespoon flour

Equipment Needed

• Pressure cooker
• Small bowl
• Whisk
• Kitchen string

Instructions

1. Begin by preparing your pressure cooker. Heat the olive oil and butter over medium heat. Ensure the butter is melted and the oil is shimmering before proceeding.

2. Add the pork loin roast to the pressure cooker. It is important to have removed the netting and retied it with kitchen string. This prevents the roast from losing its shape and allows for even browning. Brown the roast on all sides, ensuring a rich, golden color develops. This step is crucial for developing flavor and creating a beautiful crust.

3. Once the roast is nicely browned, remove it from the pressure cooker and set it aside. This prevents overcooking while you prepare the sauce base.

4. Add the chopped onion to the pressure cooker. Cook for a few minutes, until they start to soften and become translucent. Stir occasionally to prevent sticking and ensure even cooking.

5. Pour in the white wine and stir to deglaze the bottom of the pressure cooker, scraping up any browned bits. Add the Dijon mustard to the onions and wine, and stir to combine. The Dijon adds a delightful tang and depth of flavor to the sauce.

6. Place the pork loin roast back into the pressure cooker, nestled amongst the onion and wine mixture.

7. Lock the lid of the pressure cooker securely in place. Raise the temperature to high. Once the pot has reached 15psi (pounds per square inch), reduce the heat to maintain pressure and cook for 40 minutes. The precise time may vary slightly depending on your pressure cooker, so consult your manufacturer’s instructions.

8. After 40 minutes, release the pressure carefully. Once the pressure is fully released, carefully remove the pork loin roast from the pot. Cover it loosely with foil and keep in a warm place while you finish the sauce. Resting the roast allows the juices to redistribute, resulting in a more tender and flavorful final product.

9. Skim any excess fat from the liquid remaining in the pressure cooker. This step is optional but will result in a smoother and less greasy sauce.

10. Bring the liquid in the pot back to a boil over medium-high heat.

11. In a small bowl, combine the sour cream and flour, whisking until smooth and free of lumps. This mixture will act as a thickening agent for the sauce.

12. Remove the pot from the heat to prevent the sour cream from curdling. Add the sour cream mixture to the liquid, whisking continuously to form a smooth and creamy sauce. Continue whisking until the sauce thickens to your desired consistency.

13. To serve, slice the pork loin roast and generously spoon the creamy Dijon sauce over each slice. Enjoy immediately.

Expert Tips & Tricks

• Browning is key: Don’t rush the browning process. A well-browned roast will have a much richer and more complex flavor.
• Wine selection: Choose a dry white wine like Sauvignon Blanc or Pinot Grigio for the best flavor in the sauce. Avoid overly sweet wines.
• Resting the roast: Allowing the roast to rest is crucial for tenderness. Don’t skip this step!
• Sauce Consistency: If the sauce is too thick, add a tablespoon or two of water or broth to thin it out. If it’s too thin, simmer for a few more minutes to reduce it.
• Preventing Curdling: Always remove the pot from the heat before adding the sour cream to prevent curdling.

Serving & Storage Suggestions

Serve the roast pork loin hot, sliced and drizzled generously with the creamy Dijon sauce. It pairs beautifully with roasted vegetables like potatoes, carrots, and Brussels sprouts, or a simple green salad.

Leftover roast pork can be stored in an airtight container in the refrigerator for up to 3 days. The sauce should be stored separately. Reheat the pork and sauce gently in a skillet over low heat or in the microwave. You can also freeze the cooked pork loin for up to 2 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw completely in the refrigerator before reheating. The sauce is best enjoyed fresh, but can be frozen as well, though the texture may change slightly upon thawing.

FAQs (Frequently Asked Questions):

Q: Why do I need to retie the pork loin after removing the netting?
A: The netting helps the pork loin maintain its shape during cooking. Retieing it ensures the roast cooks evenly and remains compact.

Q: Can I make this without a pressure cooker?
A: Yes, you can roast the pork loin in a conventional oven at 350°F (175°C) for about 1 ½ to 2 hours, or until a meat thermometer inserted into the thickest part registers 145°F (63°C). Make the sauce on the stovetop separately.

Q: How do I know when the pork loin is cooked properly?
A: The best way to check doneness is to use a meat thermometer. Insert it into the thickest part of the roast, avoiding bone. It should read 145°F (63°C) for medium-rare.

Q: Can I use a different type of mustard?
A: While Dijon mustard is recommended for its distinct flavor, you can substitute it with other types of mustard like whole grain or yellow mustard, although the flavor profile will change slightly.

Q: Can I make the sauce ahead of time?
A: While the sauce is best made fresh, you can prepare it up to a day in advance and store it in the refrigerator. Reheat gently over low heat, whisking occasionally.
