Equipment: Nice-to-haves
- Large skillet (for searing)
- Meat thermometer
- Immersion blender or regular blender
Ingredients
- 1 pork loin (about 2 to 3 lb), trimmed of excess fat
- 1 cup pineapple chunks (fresh or canned, drained)
- 1/4 cup pineapple juice (from the can or fresh)
- 1 jalapeño, thinly sliced (remove seed for milder heat)
- 3 cloves garlic, minced
- 1/4 cup brown sugar (or packed sweetener of choice)
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 1 tablespoon rice vinegar (or apple cider vinegar)
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 1 tablespoon olive oil (for searing)
- 1 tablespoon cornstarch (for slurry)
- 2 tablespoons water (for slurry)
- 1 lime, juiced (optional finish)
- 1 tablespoon cilantro, chopped (optional garnish)
Instructions
- Pat the pork loin dry on the cutting board using paper towels so the sear behaves.
- Season the pork loin on all sides with salt, pepper, cumin, and smoked paprika so flavor gets cozy.
- Heat the large skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the pork loin in the hot skillet until the outside is a golden brown crust, turning with tongs to get all sides.
- Place the seared pork loin into the crock pot and try not to admire it too long.
- Scatter the pineapple chunks, jalapeño slices, and minced garlic around and on top of the pork loin.
- Whisk together the pineapple juice, brown sugar, soy sauce, and rice vinegar in a measuring cup, then pour the mixture over the pork loin.
- Set the crock pot to low and cover, letting the flavors take a long, relaxing nap for several hours.
- Halfway through cooking, use the wooden spoon to gently baste the pork loin with the sauce pooling in the crock pot.
- When the pork loin is close to done, check the internal temperature with the meat thermometer to ensure it reaches a safe doneness.
- Carefully remove the pork loin to a cutting board and tent it with foil so the juices redistribute.
- If you want a thicker sauce, ladle sauce into the blender or use the immersion blender until smooth and return to the crock pot.
- Create a cornstarch slurry by mixing cornstarch and water, then stir the slurry into the hot sauce to thicken, stirring with the wooden spoon.
- Slice the rested pork loin against the grain and spoon the glossy pineapple jalapeño sauce over each slice.
- Finish with lime juice squeezed over the top and a sprinkle of chopped cilantro for brightness.
Good to Know
Timing: Cook the pork loin low and slow for the juiciest results. If you’re short on time, cook on high but check the internal temperature more often.
Searing before slow cooking is optional but recommended; it adds flavor and that picture-perfect color. If you’ve got a blender, puréeing the sauce makes it silky and spoonable.
Heat level: Removing the jalapeño seeds drops the heat, but leave a few seeds if you like a gentle kick. Leftovers: Slice extra loin and use in tacos, salads, or sandwiches the next day.
Serving suggestion: Serve with rice or a simple slaw to balance the sweetness and spice. Variations: Swap pineapple for mango if you want a different tropical vibe, or use honey instead of brown sugar for a lighter sweetness.
Safety: Always check that the pork reaches a safe internal temperature before serving. Enjoy the slow-cooked magic and try not to hog all the sauce—sharing is caring, but secret second helpings are allowed.
