How to Make Spicy Balsamic Crockpot Pork Loin Recipe
Step 1: Prepare the Sauce
Start by mixing the chicken broth, balsamic vinegar, soy sauce, garlic powder, brown sugar, and one teaspoon of crushed red pepper flakes in a small bowl. This combination creates a sauce that’s tangy, sweet, and spicy—a perfect marinade and cooking liquid to infuse the pork loin with incredible flavor.
Step 2: Slice the Onions
Slice the two small yellow onions into large rings or chunks. These will layer alongside and on top of your pork loin in the crockpot, slowly softening and adding a natural sweetness that complements the spicy balsamic sauce.
Step 3: Assemble in the Crockpot
Place the pork loin in the bottom of your crockpot. Arrange the sliced onions around and on top of the meat. Pour the prepared sauce evenly over everything, ensuring the pork and onions are well coated. Finally, sprinkle the remaining teaspoon of crushed red pepper flakes over the onions for an extra pop of heat as the dish cooks.
Step 4: Slow Cook to Perfection
Set your crockpot to high and cook for 4 hours or switch to low and let it cook for 7-8 hours if you prefer a longer, slower braise. Either way, this slow cooking melts the pork into tender, juicy perfection, allowing the sauce to reduce and intensify in flavor.
Step 5: Shred and Finish Cooking
In the last 30 minutes of cooking, carefully remove the pork from the crockpot to a plate and shred it into bite-sized chunks using two forks. Return the shredded pork to the crockpot and stir it gently into the sauce and onions. This step ensures every forkful is soaking up that spicy balsamic goodness as it finishes cooking.
Step 6: Serve and Enjoy
Once the final 30 minutes are up, your Spicy Balsamic Crockpot Pork Loin Recipe is ready to be savored. Serve hot, straight from the crockpot, and enjoy the burst of flavors that only slow cooking can deliver.

Side Dishes
This pork dish pairs wonderfully with creamy mashed potatoes to soak up the flavorful sauce, or steamed green beans and roasted carrots for a fresh, light balance. For a low-carb option, try serving it over cauliflower rice or alongside sautéed kale or spinach.
Creative Ways to Present
Want to impress guests? Serve the shredded pork piled high on soft slider buns with a few slices of pickled onions, or spoon it over a bed of warm polenta. Another fun option is to toss the shredded pork into tacos with fresh avocado and crunchy slaw, showcasing the versatility of this Spicy Balsamic Crockpot Pork Loin Recipe.
Make Ahead and Storage
Storing Leftovers
Leftover pork loin should be stored in an airtight container in the refrigerator and will stay fresh for up to 3 days. The sauce helps keep the pork moist even after reheating, so you won’t lose any of that fantastically spicy balsamic flavor.
Freezing
You can freeze leftover pork in freezer-safe bags or containers for up to 3 months. Be sure to separate pork and sauce if you want to thaw only a portion. Thaw in the refrigerator overnight before reheating to maintain the best texture and taste.
Reheating
Reheat your Spicy Balsamic Crockpot Pork Loin Recipe slowly over low heat on the stovetop or in the microwave until warmed through. Adding a splash of chicken broth can help retain moisture. Stir occasionally to prevent sticking and ensure even heating.
FAQs
Can I use a different cut of pork for this recipe?
Absolutely! While pork loin is ideal for its tenderness and leanness, you can use pork shoulder for a fattier, more shred-worthy texture. Just increase the cooking time slightly to ensure it becomes tender.
How spicy is this Spicy Balsamic Crockpot Pork Loin Recipe?
The crushed red pepper flakes give the dish a noticeable but balanced heat. If you prefer less spice, simply reduce the amount or omit the extra sprinkle added during cooking. For more punch, increase the red pepper flakes or add a dash of hot sauce at serving.
Can I make this recipe without the crockpot?
Yes! You can prepare this dish in an oven-safe pot or Dutch oven. Cook at 325°F covered for about 2 to 2.5 hours, or until the pork is tender, turning the pork occasionally and basting with the sauce.
Is this recipe gluten-free?
It can be made gluten-free if you use tamari or a gluten-free soy sauce alternative instead of regular soy sauce. All other ingredients are naturally gluten-free.
What can I do with the leftover sauce?
The sauce is incredibly flavorful and can be drizzled over roasted vegetables, used as a dipping sauce for bread, or even tossed with pasta to extend your meal in delicious ways.
