Slow Roasted Pork Loin Filled With Roasted Garlic

The aroma of roasting garlic always takes me back to my grandmother’s kitchen. She wasn’t a fancy cook, but her Sunday suppers were legendary. One year, for a holiday feast, she decided to try something new: a pork loin stuffed with cloves of sweet, mellow roasted garlic. The flavor was incredible – the pork so tender it practically melted, infused with the subtle, savory sweetness of the garlic. It was a dish that felt both comforting and special, and it remains one of my most cherished food memories.

Ingredients

5-6 lbs boneless pork loin
20 cloves roasted garlic

Oil Rub:

2 tablespoons olive oil
1⁄4 teaspoon garlic powder
1⁄4 teaspoon black pepper
1⁄2 teaspoon pink peppercorns, crushed
1⁄4 teaspoon salt
1⁄4 teaspoon brown sugar
1⁄2 teaspoon dried onion flakes
1⁄2 teaspoon fresh thyme, destemmed
1 teaspoon fresh rosemary

Equipment Needed

Roasting pan
Foil
Rack
Kitchen twine or silicone bands
Paper towels

Instructions

Preheat your oven to 475 degrees Fahrenheit.
Line your roasting pan with foil for easy cleanup. Place the rack inside the foil-lined pan. The rack elevates the pork, allowing for even cooking.
Trim any excess fat from the pork loin, leaving a thin layer on top. This layer will render during roasting, adding flavor and moisture.
Cut the pork loin in half lengthwise to reduce its length. This makes it easier to manage during stuffing and roasting.
Rinse the pork loin halves under cold water and pat them dry thoroughly with paper towels. Excess moisture will hinder browning.
Prepare the oil rub by combining the olive oil, garlic powder, black pepper, pink peppercorns, salt, brown sugar, dried onion flakes, fresh thyme, and fresh rosemary in a small bowl. Mix well to combine. The pink peppercorns add a unique subtle sweetness and visual appeal, but regular black peppercorns can be substituted.
Lay one half of the pork loin on a work surface, fat side down. Rub some of the prepared oil rub on the inside surface of this half.
Arrange the roasted garlic cloves evenly over the rubbed surface of the first pork loin half. Make sure the garlic is well-distributed so every slice gets a taste.
Top the garlic-covered half with the remaining pork loin half, placing it fat side up. This positioning ensures the fat bastes the meat as it cooks.
Secure the stuffed pork loin with kitchen twine or silicone bands in approximately 4 spots along its length. This prevents the loin from falling apart during roasting. Tighten the twine firmly but not so tight that it cuts into the meat.
Rub the remaining seasoned oil rub generously over the entire surface of the roast, ensuring it’s evenly coated. This creates a flavorful crust.
Place the prepared pork loin on the rack in the roasting pan, fat side up.
Roast the pork loin uncovered at 475 degrees Fahrenheit for 10 minutes. This initial blast of high heat helps to sear the outside of the roast.
Reduce the oven temperature to 250 degrees Fahrenheit and continue roasting until the internal temperature reaches 150 to 155 degrees Fahrenheit. This slow roasting process typically takes around 3 to 4 hours, but use a meat thermometer to ensure accuracy. The exact time will depend on the thickness of the loin.
Once the internal temperature reaches the desired level, remove the pork loin from the oven and tent it loosely with foil. Let it rest for 20 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast. The internal temperature will continue to rise slightly during this time.
Remove the twine or silicone bands before slicing. Slice the pork loin thinly against the grain for maximum tenderness.

Expert Tips & Tricks

To ensure even cooking, let the pork loin sit at room temperature for about 30 minutes before roasting.
If the top of the roast starts to brown too quickly, tent it with foil during the final hour of cooking.
For a richer flavor, consider adding a splash of dry sherry or white wine to the bottom of the roasting pan before cooking. This will create flavorful steam that infuses the pork.
You can prepare the oil rub and roast the garlic a day in advance to save time on the day of cooking.
Don’t discard the pan drippings! They make a delicious jus that can be spooned over the sliced pork. Skim off any excess fat before serving.
If you want to add some color, add 1 cup of chopped onions and carrots in the roasting pan during the last hour of cooking.

Serving & Storage Suggestions

Serve the slow-roasted pork loin warm, sliced thinly. It pairs beautifully with roasted vegetables, mashed potatoes, or a simple green salad. The sweet garlic cloves inside are already a fantastic accompaniment to the pork.

Leftover pork loin should be stored in an airtight container in the refrigerator. It will keep for up to 3-4 days. You can also freeze sliced or whole portions of the pork loin for longer storage (up to 2-3 months). Thaw frozen pork loin in the refrigerator overnight before reheating.

To reheat leftover pork loin, you can gently warm it in a low oven (around 250 degrees Fahrenheit) with a splash of broth to prevent drying out. You can also microwave individual slices for a quick lunch or snack. Sliced cold pork loin is also excellent in sandwiches or salads.

Variations & Substitutions

For a spicier version, add a pinch of red pepper flakes to the oil rub.
Instead of fresh thyme and rosemary, you can use dried herbs. Use about 1 teaspoon of each.
Try stuffing the pork loin with other ingredients, such as sun-dried tomatoes, spinach, or mozzarella cheese.
If you don’t have pink peppercorns, you can substitute with regular black peppercorns or omit them altogether.
For a different flavor profile, experiment with other herbs and spices in the oil rub, such as oregano, paprika, or cumin.
To make this recipe gluten-free, ensure all ingredients, especially the oil rub components, are gluten-free.
For a richer sauce, deglaze the roasting pan with red wine after removing the pork and simmer to reduce.

FAQs (Frequently Asked Questions)

Q: Can I use pork tenderloin instead of pork loin for this recipe?
A: While you could use pork tenderloin, it’s much leaner and will cook much faster. You’ll need to reduce the cooking time significantly and watch it closely to prevent it from drying out. Pork loin is a better choice for slow roasting.

Q: How do I roast the garlic?
A: To roast the garlic, cut the top off a head of garlic, drizzle with olive oil, wrap in foil, and bake at 400 degrees Fahrenheit for about 45 minutes, or until soft and caramelized. Let cool slightly before squeezing out the cloves.

Q: What is the best way to check the internal temperature of the pork loin?
A: Use a reliable meat thermometer. Insert it into the thickest part of the pork loin, avoiding any bone (if there was any). The internal temperature should reach 150 to 155 degrees Fahrenheit.

Q: Can I make this recipe ahead of time?
A: You can assemble the pork loin ahead of time and store it in the refrigerator for up to 24 hours before roasting. However, it’s best to roast it on the day you plan to serve it for optimal flavor and texture.

Q: What are some good side dishes to serve with this pork loin?
A: Roasted vegetables like carrots, potatoes, and Brussels sprouts are excellent choices. Creamy mashed potatoes, a green bean casserole, or a simple salad would also complement the dish nicely.
