Ingredients for 5 lb pork loin crock pot
Professional-grade ingredients for restaurant-quality pork loin that transforms tough cuts into melt-in-your-mouth perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin 🥩 | 5 lb | Center-cut, 1.5-inch thickness |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Coarse grind preferred |
| Garlic Powder 🧄 | 1 tbsp | Freshly toasted for depth |
| Onion Powder 🧅 | 1 tbsp | No added MSG |
| Apple Cider Vinegar 🍎 | ¼ cup | Unfiltered for tang |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Low-Sodium Chicken Broth 🥄 | 1 cup | Homemade preferred |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only |
| Honey 🍯 | 1 tbsp | Wildflower preferred |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for searing |
The bone-in pork loin is non-negotiable for this recipe—center-cut, 1.5-inch thickness ensures even cooking and maximum tenderness. Whole Foods or your local butcher shop are ideal sources, where you can verify the cut's quality. Look for good marbling and a firm, pale pink color—avoid any meat with grayish hues or excessive fat. The 5 lb size is perfect for a crowd, but if you're cooking for fewer people, reduce proportionally while maintaining the same thickness. For the best results, pat the meat dry with paper towels before seasoning to promote a better crust during searing.
No apple cider vinegar? Red wine vinegar works in a pinch, though it lacks the subtle sweetness that complements the pork. Fresh herbs elevate this dish, but dried rosemary and thyme at one-third the amount will suffice if needed. The honey adds a delicate sweetness that balances the savory notes—substitute maple syrup if you're avoiding refined sugars. For the butter, European-style cultured butter like Plugrá provides superior flavor, though any unsalted butter will work. The olive oil should be extra-virgin—cheap oils can impart a bitter taste when heated.
This recipe reheats beautifully—store in an airtight container for up to 5 days in the fridge or 3 months in the freezer. For long-term storage, portion into individual servings before freezing to maintain texture. The pork loin should rest at room temperature for 30 minutes before slicing to ensure clean cuts. Leftovers make excellent sandwiches or can be shredded for tacos. The broth and vinegar mixture can be prepped ahead and stored separately for 1 week in the refrigerator.
Why You'll Love This Recipe
- Hands-Off Magic: I swear by this—just toss the bone-in pork loin in the crock pot with salt, pepper, and those two powders (garlic and onion), then walk away. No basting, no basting, no hovering over the stove. The bone renders down into the meat, turning it unreal—crispy edges, juicy center—while I’m free to do something that doesn’t involve standing in the kitchen.

A generous shake of kosher salt and black pepper on that pork loin, plus a dusting of garlic and onion powder, lets the meat shine. The bone-in piece? That’s where the flavor really lives—it infuses the meat with a depth that’s hard to beat, and the crust? Oh, it’s golden and addictive.

Plus, the bone adds richness without extra cost. It’s my go-to for when I need to feed the family well but keep things simple—and affordable.
Step-by-step instructions for slow-cooked pork loin
This method delivers melt-in-your-mouth pork with crispy edges and rich flavor—no risk of dryness.
Season and Sear the Pork Loin
Pat the 5 lb bone-in pork loin completely dry with paper towels. This step is crucial—moisture prevents proper browning. In a small bowl, combine all 1.5 tbsp kosher salt, 1 tbsp freshly ground black pepper, 1 tbsp garlic powder, and 1 tbsp onion powder. Rub this mixture evenly over the pork, pressing firmly so the seasoning adheres.
Heat a large oven-safe skillet over medium-high heat. Add the 2 tbsp olive oil and swirl to coat. Place the pork loin fat-side down in the skillet and sear for 5-6 minutes until the fat begins to render and the skin develops a deep golden crust. Flip the pork and sear the other side for another 4-5 minutes. The goal is to create a flavorful crust while keeping the interior tender.
Prepare the Crock Pot Base
Transfer the seared pork loin to your 6-quart crock pot. In the same skillet (don't wipe it clean—the browned bits are flavor), melt the 0.5 cup unsalted butter over medium heat. Add the 0.25 cup chopped fresh rosemary and 0.25 cup fresh thyme, stirring for 1 minute until fragrant. Pour this butter and herb mixture over the pork loin.
In a measuring cup, combine the 0.25 cup apple cider vinegar, 1 cup low-sodium chicken broth, and 1 tbsp honey. Pour this liquid mixture into the crock pot, making sure it surrounds the pork completely. The vinegar adds tang while the honey helps balance flavors and create a glossy finish.
Slow Cook to Perfect Tenderness
Cover the crock pot and cook on LOW for 8 hours. This long, slow cook time is essential for breaking down the connective tissue without drying out the meat. Real talk: Don't be tempted to rush it—patience here prevents tough, dry pork. After 6 hours, check the internal temperature using a meat thermometer. It should read 190-195°F when done.
Here's the thing—bone-in pork benefits from this extended cook time. The bone infuses flavor into the meat while the connective tissue renders down, creating a fork-tender texture. If you're short on time, you can cook on HIGH for 5-6 hours, but monitor closely to avoid overcooking.
Rest and Serve with Pan Sauce
Once the pork reaches the proper internal temperature, carefully transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for 20-30 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful.
While the pork rests, skim any fat that has risen to the surface of the crock pot liquid. Return the liquid to the crock pot and cook on HIGH for 10-15 minutes to reduce it slightly, creating a flavorful pan sauce. To serve, slice the pork loin against the grain into 1-inch thick slices. Spoon the reduced pan sauce over the top and serve immediately.
Pro Tips For Making 5 Lb Pork Loin Crock Pot
- Pat the Loin Dry: Bone-in pork loin loves a good sweat before hitting the crock pot—wipe it down with paper towels until the surface glistens. I learned this the hard way after a batch turned out bland; dry meat sears better and absorbs flavors more evenly when it’s not fighting moisture.
- Salt the Night Before: Sprinkle kosher salt generously on the pork loin and let it sit uncovered in the fridge overnight. This seasoning trick works magic for depth—no need to overdo it later, and the crust locks in better than last-minute salting.
- Low and Slow, Not Lazy: Set your crock pot to low for this 5-pound cut—high heat makes the exterior rubbery before the center hits 145°F. I used to rush it, but patience here means tender, pull-apart meat that doesn’t scream "crock pot fail."
- Skip the Overcrowding: Resist the urge to add all your veggies or sauce at once—pork loin needs room to breathe. If your crock pot is packed, cook it in batches or use a second pot. Overcrowding turns juicy into soggy, and nobody wants that.
Dietary considerations for this 5 lb pork loin crock pot
Gluten-Free Adaptations
This recipe is naturally gluten-free, but always double-check your ingredients—especially spices and broths. The garlic powder and onion powder from Penzeys are certified gluten-free, and the low-sodium chicken broth should be labeled gluten-free if you're sensitive.
The apple cider vinegar and honey are also safe, making this dish perfect for gluten-free diets without modification. 🌾
Low-Carb Modifications
For a lower-carb version, simply skip the honey and reduce the apple cider vinegar to 2 tbsp instead of ¼ cup. The pork loin itself is already a lean protein, and the butter, herbs, and broth keep it flavorful without adding carbs.
This approach keeps the dish under 5g net carbs per serving while maintaining the same rich, savory profile.
Dairy-Free Options
To make this recipe dairy-free, replace the ½ cup unsalted butter with ½ cup olive oil or vegetable oil when sautéing the herbs. The flavor won't be identical, but it still delivers a fragrant, aromatic base.
For extra richness, add 1 tbsp nutritional yeast to the crock pot liquid—it adds a cheesy depth without dairy. 🧈
Allergen-Friendly Adjustments
If you're avoiding soy, ensure your kosher salt is soy-free (some brands use anti-caking agents with soy). For nut allergies, stick to the original ingredients—no nuts are required.
The recipe is also egg-free and shellfish-free, making it safe for most common allergies. Always verify ingredient labels, especially when using store-bought broths or spices.
High-Protein Focus
This recipe is already a high-protein dish, with the 5 lb pork loin providing roughly 120g protein per serving (8 servings total). To boost protein further, add ½ cup cooked quinoa or ½ cup black beans to each serving.
Both options pair beautifully with the tender pork and complement the herby, tangy flavors without overpowering them. 💪
Meal Prep Considerations
For meal prepping, store the cooked pork loin separately from the pan sauce in airtight containers. Reheat the pork in the microwave for 2-3 minutes on 50% power, then add the sauce when serving to prevent drying.
The sauce reheats well on the stovetop over medium-low heat for 5 minutes. Portion the sauce in small containers to maintain freshness and prevent freezer burn. 📅

Frequently asked questions
Can I use a boneless pork loin instead of bone-in?
You can, but expect slightly faster cooking and less flavor infusion. Boneless pork cooks about 1 hour faster than bone-in, so reduce cook time to 6-7 hours on LOW. The bone adds depth to the flavor, but if you prefer boneless, skip the bone and increase the broth by ½ cup to compensate for lost moisture.
What if my crock pot is smaller than 6 quarts?
Use a 4-5 quart crock pot by cooking the pork on HIGH for 6-7 hours instead of LOW. The smaller capacity means more direct heat, so monitor closely after 4 hours to check for doneness. You may need to slice the pork thinner to fit comfortably in the pot.
How do I fix pork that's still tough after cooking?
If your pork is tough, it likely didn't cook long enough. Next time, extend the cook time by 2 more hours on LOW or use a meat mallet to gently pound the loin before cooking (this helps tenderize). For immediate results, slice thinly against the grain and simmer in the crock pot liquid for 30 minutes on HIGH to rehydrate.
Can I make this recipe in an Instant Pot?
Yes! Sear the pork as directed, then cook on HIGH PRESSURE for 60 minutes with 10 minutes natural release. After releasing pressure, let it rest 15 minutes before slicing. The Instant Pot version cuts cook time by about 4 hours while still delivering tender results.
What's the best way to reheat leftovers?
Reheat pork loin leftovers in the microwave for 2-3 minutes on 50% power, or in a skillet with 2 tbsp broth over medium-low heat for 5-6 minutes. To maintain moisture, add a splash of water or broth and cover with a lid while reheating.
