Ingredients for aip pork loin

AIP-compliant pork loin with crispy celery crowns—rich flavors without dairy, grains, or nightshades.

The heritage pork loin is the foundation. Look for bone-in cuts at specialty butchers—they stay juicier during slow roasting. Fresh ginger and herbs should be vibrant, not wilted. Coconut aminos from Brami or Coconut Secret provide that essential umami without soy. For bone broth, homemade from grass-fed bones delivers the deepest flavor, but store-bought AIP-compliant options like Kettle & Fire work in a pinch. The celery should be thick and sturdy—avoid thin stalks that won't crisp properly.

No coconut aminos? Dried mushrooms or seaweed powder can add umami depth. Fresh herbs wilt fast—store them in damp paper towels. The celery crowns require precise cutting: slice into 1/4-inch thick rounds, then separate into individual rings. For extra crispiness, double-fry the crowns in avocado oil. The sweet potatoes can be roasted ahead and reheated—just toss with olive oil and salt before baking. Need to substitute? Butternut squash cubes work beautifully for a different flavor profile.

Pork loin keeps best 2 days in the fridge, wrapped tightly. The celery crowns lose crispness after 1 day—best served immediately. Store sweet potatoes in a cool, dark place for 5 days. For meal prep, roast extra pork and portion with cooked sweet potatoes. Freeze portions of the celery crowns in a single layer before bagging for 3 months. The bone broth can be frozen for 6 months—just thaw overnight in the fridge before using.

Step-by-step instructions for AIP pork loin roast

Master this autoimmune protocol technique for perfectly tender pork with crispy celery crowns.

Pat the 1.5 lb heritage pork loin completely dry with paper towels—this ensures maximum crispiness. In a small bowl, combine the 0.25 cup fresh rosemary, 0.25 cup fresh thyme, 0.5 cup finely grated fresh ginger root, 2 tbsp coconut aminos, and 1 tsp sea salt. Using your hands, rub this mixture all over the pork, pressing firmly so the seasoning adheres. I like to focus extra attention on the edges and cut sides where the meat will absorb flavor most directly.

Let the seasoned pork rest at room temperature for 30 minutes while you prepare the rest of your components. This resting period allows the meat to cook more evenly and develop better texture. The ginger and coconut aminos will create a beautiful caramelized crust during roasting, so don't skip this step even if you're eager to get cooking.

Cut the 6 whole celery stalks in half lengthwise, then make a shallow vertical cut about ½ inch deep along the length of each half. This creates "crowns" that will crisp beautifully. In a small bowl, whisk together the 0.25 cup fresh lemon juice and 2 tbsp melted coconut oil. Toss the celery crowns in this mixture until evenly coated.

Heat 0.5 cup avocado oil in a large skillet over medium-high heat until shimmering. Add the celery crowns in a single layer and cook for 8-10 minutes, turning occasionally, until they're deep golden brown and crispy. Remove them to a paper towel-lined plate to drain excess oil. Here's the thing—if you see the celery starting to burn before it crisps, reduce the heat slightly. You want that perfect crunch without any bitterness.

Preheat your oven to 375°F with a rack positioned in the center. Place the seasoned pork loin on a wire rack set inside a rimmed baking sheet. This rack position allows hot air to circulate around the meat, preventing soggy bottoms. Roast for 45-50 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer in the thickest part of the loin.

About 15 minutes before the pork is done, brush it with the remaining 2 tbsp melted coconut oil to enhance browning. The pork should develop a beautiful golden crust while remaining juicy inside. If you notice the edges browning too quickly, tent the pork loosely with aluminum foil to prevent over-browning while it continues cooking to temperature.

While the pork roasts, peel and cut the 2 medium sweet potatoes into 1-inch cubes. Toss them with 1 tbsp olive oil and a pinch of sea salt until evenly coated. Spread them in a single layer on a separate baking sheet. Roast at 400°F for 25-30 minutes, stirring once halfway through, until they're tender with caramelized edges.

For extra flavor, I like to finish the roasted sweet potatoes with a sprinkle of the fresh lemon juice and a pinch of sea salt right before serving. This brightens their natural sweetness and complements the rich pork beautifully. The sweet potatoes should be fork-tender with a slightly crisp exterior—this contrast makes the dish truly satisfying.

Remove the pork from the oven and transfer it to a cutting board. Let it rest for 10-15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful. While the pork rests, place the baking sheet with drippings on the stovetop over medium heat.

Pour in the 1.5 cups bone broth and scrape up any browned bits from the bottom of the pan with a wooden spoon. Simmer for 3-5 minutes until the liquid reduces slightly and thickens into a light gravy. Slice the pork against the grain into ½-inch thick pieces. Serve the pork with the crispy celery crowns, roasted sweet potatoes, and drizzle generously with the bone broth gravy. Each bite delivers perfectly balanced flavors and textures—crispy, tender, and aromatic all at once.

Troubleshooting this dish

Pork Too Dry?

If your pork loin comes out dry, you likely overcooked it. Use a meat thermometer and remove the pork from the oven when it hits 140°F—it will rise to 145°F while resting.

I also recommend brining the pork for 30 minutes in 1 cup bone broth before roasting to lock in moisture. Never skip the 10-15 minute rest—this is when juices redistribute. 💧

Celery Not Crispy?

Celery crowns need patience—don't rush the cooking time. If they're still soggy, increase the heat to medium-high and cook for an additional 3-5 minutes. For extra crispiness, double-fry them: cook once until golden, then cool completely and fry again.

Using avocado oil (high smoke point) prevents burning while achieving that perfect crunch. I've found that cutting the celery into ¼-inch thick rounds ensures even cooking. 🧅

Uneven Browning?

Uneven browning usually means your oven isn't hot enough or the air isn't circulating properly. Rotate the pork halfway through cooking and use a wire rack to elevate it. For extra browning, brush with melted coconut oil during the last 15 minutes of cooking.

If the edges brown too quickly, tent loosely with aluminum foil. My Lodge cast iron skillet helps create that beautiful crust when searing before roasting. 🔥

Bone Broth Too Thin?

If your gravy is too thin, simmer it longer to reduce the liquid. For a thicker consistency, mix 1 tsp arrowroot powder with 1 tbsp cold water and stir into the simmering broth. If you don't have arrowroot, use 1 tbsp coconut flour instead.

Always scrape up those flavorful browned bits from the pan—they're packed with umami goodness. I like to finish with a splash of lemon juice to brighten the gravy before serving. 💫

Sweet Potatoes Undercooked?

Sweet potatoes need time to become tender. If they're still firm after 30 minutes, increase the oven temperature to 425°F and roast for an additional 10-15 minutes. Cutting them into 1-inch cubes ensures even cooking.

For extra flavor, toss with 1 tsp coconut aminos before roasting. I've found that using a rimmed baking sheet prevents spillage and allows for better air circulation. 🍠

Seasoning Not Adhering?

If your seasoning falls off, the pork wasn't dry enough. Pat it completely dry with paper towels and press the seasoning mixture firmly into the meat.

For extra grip, make a simple slurry by mixing 1 tbsp coconut aminos with 1 tsp arrowroot powder and brushing it on before applying the seasoning. This creates a sticky base that helps the herbs and spices cling.

I also recommend using fresh herbs—they're more flavorful and less likely to slide off than dried ones. 🌿
