Juicy Slow-Cooked Pork Loin

This crockpot pork loin recipe transforms an ordinary cut of meat into a memorable, succulent centerpiece with minimal effort. The slow cooking process ensures the meat stays tender and juicy while developing rich flavors that will make this dish a family favorite.

I discovered this recipe during a particularly hectic holiday season when I needed something impressive yet effortless. The aroma that filled my home as it cooked convinced me this would become a regular in my rotation, and it has never disappointed a guest yet.

Ingredients

• 3 to 5 pound pork loin roast choose a well-marbled cut for the juiciest results
• 1 tablespoon olive oil helps create a beautiful sear that locks in flavor
• 1 large onion cut into pieces adds aromatic sweetness as it breaks down
• 3 whole smashed garlic cloves infuses the meat with gentle garlic flavor without overpowering
• 1 cup chicken broth creates steam for moisture and prevents the meat from drying out
• 1 tablespoon paprika provides rich color and subtle smoky notes
• 2 teaspoons salt enhances all flavors and helps tenderize the meat
• 2 teaspoons black pepper adds classic savory warmth and slight heat

Step-by-Step Instructions

Create the Seasoning Blend

Combine paprika, salt, and black pepper in a small bowl until evenly mixed. This simple rub creates a flavorful crust that will season the entire roast as it cooks. Make sure to mix thoroughly so the spices distribute evenly.

Prepare and Sear the Pork

Pat the pork loin dry with paper towels to ensure proper browning. Apply the seasoning mixture generously over the entire surface, pressing gently to adhere. Heat olive oil in a large skillet until shimmering. Carefully place the pork loin in the hot skillet and sear for 2 to 3 minutes per side until a rich brown crust forms all around. This crucial step develops deep flavor compounds that will infuse throughout the meat during slow cooking.

Set Up the Slow Cooker

Scatter the onion pieces and smashed garlic cloves across the bottom of your slow cooker. They create a flavorful bed for the pork while protecting it from direct heat. Pour the chicken broth into the slow cooker. This liquid will generate steam and help keep the environment moist. Transfer the seared pork loin to the slow cooker, placing it on top of the onion and garlic.

Slow Cook to Perfection

Cover the slow cooker with its lid and set to LOW heat. Cook for 3 to 4 hours, depending on the size of your roast. The pork is done when a meat thermometer inserted into the thickest part reads 145°F. Avoid opening the lid during cooking as this releases accumulated heat and steam, potentially extending cooking time.

Rest and Serve

Once done, carefully remove the pork loin to a cutting board. Allow it to rest for at least 5 minutes before slicing. This resting period allows juices to redistribute throughout the meat for maximum tenderness. Slice against the grain into portions and serve with some of the cooking liquid spooned over the top if desired.

Save This

The smashed garlic cloves are my secret weapon in this recipe. Rather than mincing them, keeping them whole allows them to slowly infuse the cooking liquid without becoming bitter. My husband, who typically avoids garlic, never complains about this preparation and often reaches for seconds.

Make-Ahead Options

This pork loin can be fully prepared up to two days before serving. Complete the cooking process, then cool the meat completely before refrigerating. When ready to serve, slice the cold pork thinly and reheat gently in its reserved cooking liquid in a covered pan over low heat. This method actually enhances the flavor as the meat has time to absorb more of the seasonings.

Serving Suggestions

Transform this versatile pork loin into multiple meals throughout the week. Serve thick slices alongside roasted vegetables and mashed potatoes for a traditional dinner. The next day, thinly slice the leftovers for sandwiches with grainy mustard and pickles. For a third meal, shred any remaining pork and toss with barbecue sauce for quick pulled pork sandwiches or crisp it up in a skillet for pork carnitas tacos.

Flavor Variations

While the basic recipe creates a wonderfully flavorful roast, you can customize it to your preferences. For a sweeter profile, add 2 tablespoons of brown sugar to the rub mixture and place apple slices in the bottom of the slow cooker. For an herb-forward version, add 1 tablespoon each of dried rosemary and thyme to the seasoning blend and use white wine instead of chicken broth in the slow cooker. For a spicy kick, incorporate 1 teaspoon of cayenne pepper into the rub and add sliced jalapeños to the slow cooker.

Common Questions

→ Can I cook this pork loin on HIGH instead of LOW?

Yes, you can cook the pork loin on HIGH, but reduce the cooking time to approximately 2-3 hours. However, cooking on LOW is recommended for the most tender results. Always use a meat thermometer to ensure the internal temperature reaches 145°F (63°C) for food safety.

→ How can I tell when my pork loin is done without a meat thermometer?

While a meat thermometer is the most reliable method, without one you can check by cutting into the thickest part - the meat should be slightly pink in the center but not raw. The pork should also feel firm yet tender when pressed. Modern pork is safe with a slight pink center, which helps maintain juiciness.

→ What sides pair well with this slow-cooked pork loin?

This versatile pork loin pairs beautifully with mashed or roasted potatoes, steamed vegetables like green beans or broccoli, a fresh garden salad, or apple sauce. For a complete low-carb meal, serve with cauliflower mash and roasted Brussels sprouts.

→ Can I add other vegetables to the slow cooker with the pork?

Absolutely! Root vegetables like carrots, parsnips, or potatoes work especially well as they can withstand the long cooking time. Add them around the pork after placing it in the slow cooker. For more delicate vegetables like green beans or bell peppers, add them during the final hour of cooking to prevent them from becoming mushy.

→ How long will leftover pork loin keep in the refrigerator?

Properly stored in an airtight container, leftover pork loin will keep for 3-4 days in the refrigerator. For longer storage, you can freeze portions for up to 3 months. Thaw overnight in the refrigerator before reheating gently in the microwave or oven with a splash of broth to maintain moisture.

→ Can I use different seasonings for the rub?

Definitely! While the basic paprika, salt and pepper rub provides excellent flavor, you can customize with additional herbs and spices. Try adding garlic powder, onion powder, dried thyme, rosemary, or a touch of brown sugar for sweetness. For a smoky variation, incorporate smoked paprika or a small amount of cumin.
