Ingredients

2 1/2 lbs boneless top loin pork roast
1 1/2 cups fresh rosemary leaves
12 garlic cloves
3 tablespoons olive oil
2 tablespoons balsamic vinegar
1 teaspoon salt
2 teaspoons black pepper
2 1/2 lbs small red potatoes, cut into wedges

Equipment Needed

Food processor
Shallow roasting pan
Large bowl
Cutting board
Meat thermometer

Instructions

Preheat your oven to 450°F (232°C). This initial high heat helps to create a beautiful sear on the pork.
Prepare the flavorful rosemary-garlic paste. In a food processor, combine the fresh rosemary leaves, garlic cloves, olive oil, balsamic vinegar, salt, and black pepper. Pulse the mixture until you achieve a coarse, wet paste. The consistency should be spreadable but still have some texture from the rosemary.
Season the pork roast. Spread approximately 3/4 of the prepared paste generously on all sides of the boneless top loin pork roast. Ensure the roast is evenly coated to maximize the flavor infusion.
Sear the pork. Place the coated pork roast, fat side up, in a shallow roasting pan. Make sure the roasting pan is large enough to hold the roast with about 3 inches of space around all sides. Cook in the preheated oven for 15 minutes. This initial burst of high heat helps to develop a rich, flavorful crust.
Prepare the potatoes. While the pork is searing, in a large bowl, combine the red potato wedges with the remaining rosemary-garlic paste. Toss the potatoes thoroughly to ensure they are evenly coated with the flavorful mixture.
Reduce oven temperature and add potatoes. After the initial 15-minute sear, reduce the oven temperature to 350°F (175°C). Place the coated potatoes around the roast in the roasting pan.
Roast the pork and potatoes. Continue to cook the pork roast and potatoes for 50-60 minutes. Toss the potatoes halfway through the cooking time to ensure they brown evenly on all sides.
Check for doneness. Use a meat thermometer to check the internal temperature of the pork roast. Cook until the internal temperature reaches 150°F (65°C). If the potatoes are not fully cooked at this point, transfer the roast to a cutting board, cover loosely with foil, and continue cooking the potatoes until they are tender.
Rest and slice. Remove the pork roast from the oven and let it rest for 10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. Slice the pork roast and arrange it on a platter with the roasted potatoes.

Expert Tips & Tricks

Herb Infusion: For an even more intense rosemary flavor, consider using a mortar and pestle to grind the rosemary with the garlic and salt before adding the other ingredients to the food processor. This releases the essential oils in the rosemary, intensifying the aroma and flavor.
Browning Boost: If you want to achieve an even deeper, richer color on the pork, brush it with a little bit of honey or maple syrup during the last 15 minutes of cooking.
Potato Perfection: For extra crispy potatoes, soak the potato wedges in cold water for about 30 minutes before tossing them with the rosemary paste. This helps to remove excess starch and encourages browning.
Make-Ahead Tip: The rosemary-garlic paste can be made up to 2 days in advance and stored in an airtight container in the refrigerator. This will save you time on the day you plan to cook the pork roast.
Prevent Dryness: To ensure a moist and juicy pork roast, consider using a brine. Submerge the pork roast in a saltwater solution (approximately 1/2 cup salt per gallon of water) for several hours or overnight before cooking. This will help the pork retain moisture during the roasting process.
Gravy Option: For a delicious pan gravy, deglaze the roasting pan with a little chicken broth or red wine after removing the pork and potatoes. Scrape up any browned bits from the bottom of the pan and simmer until the gravy thickens slightly.

Serving & Storage Suggestions

Serve the Balsamic Rosemary Pork Loin immediately after slicing, accompanied by the roasted potatoes. Garnish with a sprig of fresh rosemary for an elegant presentation. This dish pairs well with a variety of sides, such as a green salad, roasted vegetables (asparagus, Brussels sprouts), or a creamy polenta.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat the pork and potatoes in the oven or microwave until warmed through. The pork is best reheated gently to prevent it from drying out.

For longer storage, the cooked pork can be frozen for up to 2-3 months. Wrap the pork tightly in plastic wrap and then in aluminum foil to prevent freezer burn. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of pork for this recipe?
A: While a boneless top loin roast is recommended, you can also use a pork tenderloin or a bone-in pork loin roast. Adjust the cooking time accordingly based on the thickness of the roast.

Q: How do I know when the pork is fully cooked?
A: The best way to ensure the pork is cooked to the correct temperature is to use a meat thermometer. Insert the thermometer into the thickest part of the roast, avoiding any bone. The internal temperature should reach 150°F (65°C) for medium-rare or 160°F (71°C) for medium.

Q: Can I cook this pork roast in a slow cooker?
A: Yes, you can adapt this recipe for a slow cooker. Sear the pork roast on all sides in a skillet before placing it in the slow cooker. Add the potatoes and rosemary-garlic paste, and cook on low for 6-8 hours or on high for 3-4 hours.

Q: What if my potatoes are not done when the pork is finished cooking?
A: If the potatoes are not fully cooked when the pork reaches the desired internal temperature, remove the pork from the oven and let it rest on a cutting board, covered loosely with foil. Continue cooking the potatoes until they are tender, checking them every 10-15 minutes.

Q: Can I prepare the pork roast ahead of time?
A: You can prepare the pork roast up to a day in advance by coating it with the rosemary-garlic paste and storing it in the refrigerator. Bring the pork to room temperature for about 30 minutes before cooking.
