Equipment: Nice-to-haves

Ingredients
- 1 pork loin (about 2–3 lb), trimmed of excess fat
- 2 tablespoons Dijon mustard
- 2 tablespoons whole-grain mustard
- 2 tablespoons honey
- 1 tablespoon olive oil
- 3 cloves garlic, minced
- 1 small onion, thinly sliced
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1/2 teaspoon dried sage
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup low-sodium chicken broth
- 1 tablespoon apple cider vinegar
- 1 tablespoon cornstarch (for thickening)
- 1 tablespoon cold water (for slurry)
- 1 sprig fresh rosemary (for garnish, optional)
- 1 tablespoon chopped fresh parsley (for garnish, optional)
Instructions
- Pat the pork loin dry and season it all over with salt and pepper; treat it like it’s getting ready for its close-up.
- If you’re using kitchen twine, tie the pork loin at intervals so it cooks evenly and looks like it went to charm school.
- Heat a skillet over medium-high heat with olive oil and sear the pork loin on all sides until golden; this step is optional but gives you extra flavor and respectable browning.
- Place the sliced onion in the bottom of the crock pot and set a wire rack on top if you have one, otherwise nestle the pork directly on the onion bed.
- Whisk together the Dijon mustard, whole-grain mustard, honey, minced garlic, dried thyme, dried rosemary, dried sage, and apple cider vinegar in a mixing bowl to make the mustard herb glaze.
- Pour the chicken broth into the crock pot around the pork, not over it, so the glaze stays glorious and not drowned.
- Spoon most of the mustard herb glaze over the pork loin, reserving a bit for finishing and basting later.
- Cover and cook on low until the pork reaches a safe internal temperature as read by the meat thermometer; this is when patience pays off in juicy rewards.
- If you’re short on time, cook on high until done, but low gives you the gold-standard tenderness.
- About 20 minutes before the end of cooking, uncover and brush the reserved glaze over the pork so it gets sticky and beautiful.
- Remove the pork loin from the crock pot and let it rest on a cutting board; resting keeps the juices where they belong — inside the meat.
- Strain the cooking liquid into a saucepan, skim off any excess fat, and bring it to a simmer.
- Mix the cornstarch with cold water to make a slurry, then whisk it into the simmering liquid until it thickens into a glossy sauce.
- Slice the pork loin against the grain into medallions and arrange on a serving platter.
- Drizzle the thickened sauce over the sliced pork and garnish with fresh rosemary and parsley for a pop of color and credibility.
- Serve with your favorite sides and bask in the compliments while pretending you didn’t have to babysit the oven.
Good to Know
Timing tip: Cooking times vary by crock pot. Low setting usually takes several hours, so plan accordingly.
That’s why using a meat thermometer is non-negotiable — aim for a safe but juicy internal temperature. Flavor hack: Searing is optional but recommended; it builds flavor and gives the pork a pretty color.
Make-ahead: The pork reheats beautifully and the sauce thickens overnight; leftovers are excellent for sandwiches. Variation: Swap honey for maple syrup for a deeper sweetness, or add a splash of soy sauce for umami.
Serving suggestion: Pair with mashed root vegetable, roasted green vegetable, or a simple grain — carbs are your friend here. Diet notes: This recipe is gluten-free if you use gluten-free cornstarch and broth.
One last joke: If someone asks for the recipe, tell them it’s a family secret — then send them this post. Everyone wins.
