Ingredients for mississippi pork loin crock pot
Sixteen ingredients. Six hours. A Mississippi pork loin that tastes like a Sunday supper.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin Roast 🥩 | 3 lb | Bone-in preferred for flavor |
| Yellow Onions 🧅 | 2 whole | Thinly sliced for gravy |
| Celery Stalks 🥬 | 6 whole | For crowns, trimmed |
| Garlic Cloves 🧄 | 6 cloves | Minced for seasoning |
| Dried Thyme 🌿 | 1 tbsp | Or 1 tbsp fresh thyme |
| Smoked Paprika 🌶️ | 1 tbsp | For smoky depth |
| Ground Black Pepper 🌶️ | 1 ½ tsp | Freshly ground preferred |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Brown Sugar 🍯 | 2 tbsp | Light or dark |
| Apple Cider Vinegar 🍎 | 2 tbsp | For tangy balance |
| Chicken Broth 💧 | 2 cups | Low-sodium preferred |
| All-Purpose Flour 🌾 | 2 tbsp | For gravy thickening |
| Butter 🧈 | 2 tbsp | Unsalted for gravy |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
The pork loin is the star—look for a roast with good marbling at Kroger or your local butcher. Bone-in stays juicier, but boneless works too if you're in a hurry. Costco often has great deals on whole pork loins, but check the sell-by date. The celery crowns are key: pick firm stalks with no brown spots. For the gravy, low-sodium chicken broth keeps things balanced, but homemade stock works even better. I always grab extra thyme—half goes in the crock pot, half gets toasted for the celery crowns.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Short on vinegar? Lemon juice works in a pinch. The flour for gravy can be swapped for cornstarch if you're gluten-free, but trust me on the full-fat cream—it makes the gravy silky. For the celery crowns, dip in egg wash first before breading with flour. The onions? Caramelize them in a skillet first for extra sweetness, but the slow cooker will do some of that work too.
Pork stays tender for 4 days in the fridge—reheats beautifully. The celery crowns crisp up best when made fresh, but you can bake them ahead and reheat at 375°F for 5-10 minutes. Gravy can be made in advance and reheated with a splash of broth. Store everything in airtight containers. This recipe doubles easily—just scale up the pork and broth proportionally. Leftovers make amazing sandwiches the next day.
Why You'll Love This Recipe
- Set-It-Forgot-It Magic: I swear by this recipe when I’ve got better things to do than stand by the stove. Toss the pork loin, chopped onions, celery, and garlic into the crock pot with a sprinkle of thyme, add some broth, and let it slow-cook while you handle life—no hovering required. The onions caramelize just enough to give that deep, savory sweetness without any extra work.
- Southern Comfort in a Bowl: That thyme and garlic combo? It’s like a warm hug from Mississippi—earthy, familiar, and just rich enough to satisfy. The pork stays juicy with a tender bite, and the onions add this subtle caramelized depth that makes it taste like a Sunday dinner, not a weeknight meal. Honestly, I’ve had people ask if I spent hours on it, and I just laugh while I eat seconds.
- Leftovers That Don’t Suck: Between us, most slow-cooker leftovers are sad. Not this one. The pork shreds perfectly, and the flavors only get better the next day—great for sandwiches, salads, or even breakfast hash. I’ve packed this for lunches all week, and my kids still beg for it. (Yes, even on a Tuesday night.)
- Budget-Friendly Crowd-Pleaser: Pork loin is leaner than ribs but just as impressive, and this recipe stretches it across multiple meals without breaking the bank. A single roast feeds my family of four for days, and the onions and celery are the kind of cheap veggies that make frugal cooking feel generous. Plus, the thyme adds that gourmet touch without costing a fortune.
Step-by-step instructions for Mississippi pork loin crock pot recipe
This slow-cooked masterpiece delivers tender pork with crisp celery crowns and rich onion gravy—every bite packed with Southern flavor.
Season and Sear the Pork Loin
Pat the 3 lb pork loin roast completely dry with paper towels. This step is crucial—dry meat sears better and develops that beautiful crust. In a large skillet over medium-high heat, add 2 tablespoons butter and let it melt completely, then add the pork and sear on all sides for 3-4 minutes per side until you see a deep golden-brown color.
While the pork sears, mix together 1.5 teaspoons kosher salt, 1.5 teaspoons ground black pepper, 1 tablespoon smoked paprika, 1 tablespoon dried thyme, and 2 tablespoons brown sugar in a small bowl. Once the pork is browned, remove it from the skillet and rub the spice mixture all over, pressing it into the surface. Let it cool for 5 minutes before transferring to your crock pot.
Prepare the Celery Crowns and Onions
Trim the 6 whole celery stalks by cutting off the leafy tops and the bottoms, leaving about 3 inches of stalk. Slice each stalk into ¼-inch thick rounds—these will become the crispy celery crowns. Thinly slice the 2 whole yellow onions, keeping the layers intact for the gravy. Set both aside for now.
In the same skillet you seared the pork, add 6 minced garlic cloves and sauté for 30 seconds until fragrant. Then pour in 2 tablespoons apple cider vinegar and scrape up any browned bits from the bottom of the pan. This flavorful mixture will deepen the taste of your pork and gravy.
Slow Cook the Pork
Place the seasoned pork loin into the crock pot and surround it with the sliced onions and celery crowns. Pour in 2 cups chicken broth and bring the mixture to a boil over high heat on the stovetop for 2 minutes to deglaze the pot. Then reduce the heat to low and cover the crock pot.
Cook the pork for 6-7 hours on low heat, or until the internal temperature reaches 145°F and the meat is fork-tender. The celery crowns will soften slightly but retain their shape. Here's the thing—don't peek or lift the lid during cooking. Every time you open it, you release heat and moisture, which can turn your tender pork into dry meat.
Make the Sweet Onion Gravy
Once the pork is done, carefully remove it from the crock pot and place it on a cutting board to rest for 10 minutes. In a saucepan over medium heat, melt 2 tablespoons butter and whisk in 2 tablespoons all-purpose flour to form a roux. Cook for 1-2 minutes until the mixture bubbles and turns golden brown.
Gradually whisk in the cooking juices from the crock pot, about 1 cup at a time, until smooth. Add 0.5 cup heavy cream and stir until the gravy thickens to your desired consistency. Taste and adjust seasoning with additional salt and pepper if needed. The gravy should coat the back of a spoon and be rich but not gluey.
Serve with Crispy Celery Crowns
Slice the pork loin into ½-inch thick slices against the grain for maximum tenderness. Arrange the slices on a platter and ladle the sweet onion gravy over the top. The celery crowns should be lightly crisped in a separate skillet with a bit of butter for 2-3 minutes until golden brown before serving alongside the pork.
This dish is best served immediately while the pork is still juicy and the celery crowns are crisp. Each bite delivers a perfect balance of smoky, sweet, and savory flavors that make this Mississippi classic unforgettable. Don't forget to save some gravy for leftovers—it reheats beautifully and tastes even better the next day!
Pro Tips For Making Mississippi Pork Loin Crock Pot
- SEAR THE PORK FIRST: That crock pot sauce needs something to cling to, and raw pork absorbs liquid like a sponge. Hit the pork with a quick 3-minute sear in a hot skillet—just until golden—before dumping it in. The crust makes all the difference when you slice into tender, flavor-packed meat later.
- CHOP ONIONS COARSE: Tiny diced onions turn to mush in a long cook. For this recipe, cut them into ½-inch chunks—they’ll soften but stay identifiable, adding real texture to each bite. Same goes for celery: bigger pieces mean better mouthfeel.
- DON’T OVERFILL THE POT: I learned this the hard way—packing the crock too tight means uneven cooking and a sad, watery pork loin. Fill it no more than halfway with veggies and broth, then let the meat sit loose. The liquid will rise, but the pork won’t steam in its own juices.
- ADD THYME LATE: Dried thyme loses its punch when simmered too long. Tuck a sprig or two into the pork after the first 2 hours of cooking, then remove it before serving. Fresh thyme works even better—just add it in the last 30 minutes.
Make-ahead tips for this dish
Prep Ahead Strategy
Start by fully prepping the celery crowns and onions the night before—slice them and store in airtight containers in the fridge. This saves you 30 minutes of prep day-of.
I always do this because handling celery can be tedious, and prepping it early means you can focus on searing the pork fresh. 🥬
Slow-Cooker Prep
Season the pork loin and sear it up to 2 days ahead—store it in the fridge in an airtight container with the spices clinging to the surface. When ready to cook, transfer it directly to the crock pot without thawing.
This method works because the pork will still develop flavor beautifully during the slow cook. The key is to keep it covered until cooking time.
Gravy Prep Shortcut
Make the gravy 24 hours ahead and store it in a sealed jar in the fridge. When reheating, add a splash of chicken broth to loosen it up—it thickens as it cools. I like to keep a jar of gravy on hand for last-minute meals because it’s the easiest part to prep in advance. Just
Celery Crown Make-Ahead
For the crispy celery crowns, you can bake them ahead and reheat before serving. Toss the sliced celery in 1 tbsp flour, then bake at 375°F for 15 minutes until golden. Store in an airtight container and reheat in a skillet with 1 tbsp butter for 2-3 minutes to restore crispness. This is my go-to trick for busy weeknights.
Full Meal Prep
This recipe preps like a dream for meal prep. Cook the pork and gravy as directed, then portion everything into glass containers with airtight lids. The pork stays tender for 4 days, and the gravy reheats perfectly.
To serve, simply reheat the pork and gravy together, then crisp the celery crowns fresh. It’s a game-changer for family dinners. ⏰
Freezer-Friendly
Freeze the cooked pork loin in portions for up to 3 months. Thaw overnight in the fridge before reheating. The gravy can also be frozen—just add a splash of broth when reheating to restore its silky texture.
I always freeze half the batch because it’s too good to waste, and reheating it later feels like a cozy treat. 🧊

Frequently asked questions
Can I use boneless pork loin instead of bone-in?
Yes, you can absolutely use boneless pork loin! The recipe will still turn out tender and flavorful. Just keep in mind that boneless cuts may cook slightly faster, so check the internal temperature after 5-6 hours on low. The key is to avoid overcooking—boneless pork is more prone to drying out if left too long.
What's the best way to crisp the celery crowns?
For perfect crispy celery crowns, toss the sliced rounds in 1 tablespoon flour first, then pan-fry in 2 tablespoons butter over medium-high heat for 2-3 minutes until golden. The flour creates a light crust, while the butter adds richness. Pro tip: Don't overcrowd the pan or they'll steam instead of crisp!
Can I make this recipe in an Instant Pot?
Use the Sauté function to sear the pork, then cook on Low (200°F) for 60 minutes with 15 minutes natural release. The celery crowns will soften faster, so crisp them fresh in a skillet before serving. The gravy method remains the same—just use the cooking juices from the Instant Pot for the roux.
Why does my gravy turn out too thick?
Gravy thickens as it cools, so always stir in a splash of chicken broth when reheating. If it's still too thick, thin it gradually with more broth, 1 tablespoon at a time. The recipe calls for a roux, which naturally thickens the gravy—just remember that it will continue thickening as it sits, so start with a slightly looser consistency.
What are good side dishes to serve with this?
This Mississippi-style pork loin pairs perfectly with classic Southern sides like creamy mac and cheese, buttery cornbread, or sautéed collard greens. For a lighter option, try a fresh cucumber salad or roasted sweet potatoes. The sweet onion gravy complements all of these beautifully!
