Diana’s Easy Crock Pot Pork Loin

The aroma of slow-cooked pork, simmering gently with onions and herbs, always brings me back to Sunday dinners at my grandmother’s house. She had a way of making simple, comforting food feel like a celebration.

Instructions

Begin by ensuring your pork loin is completely dry. Pat it down thoroughly with paper towels. This is crucial for achieving a good sear.
Add 2 tablespoons of vegetable oil to your frying pan and set the stove to high heat. We want that pan nice and hot!
Coat the pork loin with the remaining 1 tablespoon of vegetable oil and season generously with salt and pepper on all sides. Don’t be shy – this is where a lot of the flavor comes from.
Once the oil is shimmering and hot (test by flicking a drop or two of water into the pan; it should dance), carefully add the pork loin to the skillet.
Brown the pork loin on all sides, including the ends. Resist the urge to move the meat too soon! Allow it to sear for 3-5 minutes on each side to develop a beautiful crust. The exact time will depend on your stove and pan’s heat.
Once the pork loin is beautifully browned, remove it from the frying pan and transfer it to your crock pot.
Cover the pork loin with the sliced onions, then sprinkle the onion soup mix evenly over the top.
Now, for the sauce. In a separate bowl, combine the beef broth, bay leaf, Worcestershire sauce, and minced garlic.
Deglaze the skillet you used to brown the pork. Pour the beef broth mixture into the hot skillet and use a spatula to scrape up any browned bits stuck to the bottom of the pan. These browned bits are packed with flavor and will add depth to your sauce.
Turn off the heat and pour this flavorful sauce over the pork loin in the crock pot.
Cover the crock pot with the lid and cook on low for 6-8 hours or on high for 4-6 hours. The cooking time will vary depending on your crock pot, so check for doneness periodically.
The pork loin is done when it is tender and easily pulled apart with a fork.
Once the pork loin is cooked through, remove it from the crock pot and transfer it to a serving platter.
Now, let’s make the gravy. In a small bowl, whisk together 2 tablespoons of cold water and 2 tablespoons of all-purpose flour until smooth. This is a slurry, and using cold water helps prevent lumps from forming when you add it to the hot juices.
Pour the remaining juices from the crock pot into the skillet.
Add the flour slurry to the skillet with the pork juices.
Heat the mixture to a boil over medium heat, stirring constantly with a whisk. Continue to cook until the gravy has thickened to your desired consistency.
If the gravy is too thick, add a little more beef broth or water to thin it out. If it’s too thin, continue cooking it until it reduces and thickens.
The general rule for flour to liquid ratio is 2 tablespoons of flour per 1 cup of liquid. So if you have more than 1 cup of liquid make sure to adjust your flour, still making sure to use the cold water mixing to stop lumping.
Slice the pork loin and serve it with the homemade gravy.

Expert Tips & Tricks

For extra flavor, consider adding a sprig of fresh rosemary or thyme to the crock pot along with the bay leaf.
If you don’t have beef broth on hand, you can use chicken broth or vegetable broth as a substitute.
To prevent the pork from drying out, make sure to keep the lid on the crock pot during cooking.
If you want a thicker gravy, you can add a little more flour to the slurry. Just be sure to whisk it in well to avoid lumps.
Browning the pork loin is a critical step for flavor development. Don’t skip it! The Maillard reaction creates complex flavors that simply can’t be replicated by slow cooking alone.

Serving & Storage Suggestions

Serve the sliced pork loin immediately, drizzled generously with the homemade gravy. It’s delicious with classic sides like mashed potatoes, roasted vegetables, or even just a simple green salad. Homemade garlic toast or crusty french bread is also a welcome addition to soak up all that delicious gravy.

Leftover pork loin can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave or oven until warmed through. The gravy can also be stored separately in the refrigerator for the same amount of time.

For longer storage, you can freeze the cooked pork loin and gravy separately. Wrap the pork tightly in plastic wrap or freezer paper before freezing. The gravy can be frozen in a freezer-safe container. Both will keep well in the freezer for up to 2-3 months. To reheat, thaw overnight in the refrigerator and then reheat gently as described above.

FAQs (Frequently Asked Questions)

Q: Can I use a frozen pork loin for this recipe?
A: It’s best to thaw the pork loin completely before cooking it in the crock pot. Cooking frozen meat in a slow cooker can lead to uneven cooking and may not reach a safe internal temperature.

Q: How do I prevent the pork loin from drying out?
A: Don’t overcook it! Use a meat thermometer to ensure the pork reaches an internal temperature of 145°F (63°C). Also, make sure the lid is tightly sealed on the crock pot.

Q: Can I make this recipe ahead of time?
A: Yes, you can brown the pork loin and prepare the sauce a day in advance. Store them separately in the refrigerator and then combine them in the crock pot the next day.

Q: What if my gravy is too thin?
A: Continue cooking the gravy in the skillet over medium heat, stirring constantly, until it reduces and thickens. You can also add a little more flour slurry if needed.

Q: Can I use a different cut of pork for this recipe?
A: While pork loin is ideal, you could also use a pork shoulder or pork butt roast. However, these cuts are fattier and require longer cooking times.
