Ingredients
- 1 pork loin (about 2 to 3 pound)
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 onion, sliced
- 3 clove garlic, minced
- 1/2 cup brown sugar
- 1/3 cup Dijon mustard
- 1 tablespoon whole grain mustard
- 1 tablespoon apple cider vinegar
- 1 tablespoon soy sauce
- 1/2 cup chicken broth
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1 tablespoon cornstarch
- 1 tablespoon water
- 1 tablespoon butter
- 1 tablespoon parsley, chopped (for garnish)
Instructions
- Pat the pork loin dry on the cutting board and season all over with salt and pepper.
- Drizzle the pork with olive oil and rub it in so the seasoning sticks like it means it.
- If you want extra flavor, heat the cast iron skillet and sear the pork on all sides until browned using the pair of tongs.
- Place the sliced onion in the bottom of the slow cooker to act like a cozy flavor bed.
- Set the pork on top of the onion in the slow cooker.
- In the small bowl whisk together brown sugar, Dijon mustard, whole grain mustard, apple cider vinegar, soy sauce, garlic, smoked paprika, dried thyme, and chicken broth until smooth.
- Pour about half of the mustard mixture over the pork and reserve the rest for glazing and sauce finishing.
- Cover and cook on low until the pork reaches a safe internal texture and is fork-tender, or on high if you’re short on time.
- Check the pork with the meat thermometer toward the end to avoid overcooking; aim for the pork to be tender and juicy.
- Carefully remove the pork to the serving platter and let it rest while you make the sauce.
- Transfer the cooking liquid to the cast iron skillet and bring it to a gentle simmer on the stove.
- Whisk the cornstarch and water in the small bowl to make a slurry and stir it into the simmering sauce to thicken, using the whisk until glossy.
- Stir the butter into the sauce until melted for extra shine and richness.
- Brush the reserved mustard mixture and the reduced sauce over the pork with the silicone brush, or spoon it on if you’re improvising.
- Slice the pork against the grain on the cutting board and drizzle more sauce over the slices before plating.
- Garnish with parsley on the serving platter and serve with extra sauce on the side for dunking or dramatic swooning.
Good to Know
Tip: Searing the pork first is optional but gives a deeper flavor and a prettier color. Tip: Cooking time varies by size; slow and low makes the meat tender, but quick and high works in a pinch.
That’s why a meat thermometer is a great friend—no guesswork, just juicy results. Variation: Swap Dijon for honey mustard if you want a sweeter edge.
Variation: Add a bay leaf if you crave herbal notes, but remove it before serving. Serving suggestion: Serve with mashed potato or roasted vegetable to soak up the sauce.
Make-ahead: The pork tastes even better the next day; store sliced pork and sauce separately and reheat gently. Cleanup hack: Line the slow cooker with a removable liner or put the browned pan into warm soapy water while you eat—wise multitasking.
Final note: This recipe is beginner-friendly and delivers big flavor with small effort—so go ahead, tell people you slaved over dinner, and we won’t tell.
