- tongs
- meat thermometer

Equipment: Nice-to-haves
- skillet (for searing)
- basting brush
- kitchen twine
- serving platter

Ingredients
- 1 pork tenderloin (about 1 lb)
- 1/3 cup honey
- 1/4 cup Dijon mustard
- 2 tablespoons whole-grain mustard
- 1 small onion, thinly sliced
- 1 clove garlic, minced
- 1 tablespoon olive oil
- 1 tablespoon soy sauce
- 1 tablespoon apple cider vinegar
- 1 teaspoon smoked paprika
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon cornstarch (for slurry)
- 2 tablespoons water (for slurry)
- Fresh parsley for garnish (optional)

Instructions
- Pat the pork tenderloin dry with paper towel and season it evenly with salt, pepper, and smoked paprika on all sides using the chef knife and cutting board to trim any silver skin first.
- If you have kitchen twine, tie the tenderloin at even intervals to keep a uniform shape so it cooks evenly; if not, no drama—skip it.
- Heat the skillet with olive oil and sear the tenderloin on all sides until golden to build flavor, then transfer it to the slow cooker using the tongs.
- In the mixing bowl, whisk together honey, Dijon mustard, whole-grain mustard, minced garlic, soy sauce, apple cider vinegar, and sliced onion until shiny and smooth; that’s your glaze.
- Pour half of the glaze into the bottom of the slow cooker and nestle the seared tenderloin on top so it bathes in flavor.
- Spoon the remaining glaze over the pork to coat the top—use the basting brush if you want to look like you planned this.
- Cover and cook on low until the meat thermometer reads the safe internal temperature and the pork feels tender; that’s your cue.
- Remove the pork to the serving platter and tent it with foil to rest so juices redistribute and you don’t get sad, dry meat.
- Meanwhile, pour the cooking liquid into the skillet and bring to a simmer to reduce and concentrate the glaze flavors; mash any onion into the sauce with a spoon.
- Whisk cornstarch and water into a smooth slurry and stir it into the simmering sauce until it thickens and glazes—then taste and adjust seasoning.
- Slice the rested pork into medallions and drizzle the thickened honey mustard sauce over the top; garnish with parsley if you’re feeling fancy.
- Serve immediately with your favorite side while pretending this was effortless—because it mostly was.

Good to Know
Tip: Always use a meat thermometer to check doneness; the target is an internal temperature of 145°F followed by a short rest. That’s why your pork stays juicy and not tragic.
Variation: Swap the whole-grain mustard for extra Dijon or use maple instead of honey for a deeper, caramel flavor. But here’s the catch!
If you swap sweeteners, taste the glaze before glazing the pork so it’s not too sweet. Make-ahead: You can mix the glaze a day ahead in the mixing bowl and refrigerate it.
That saves time and gives flavors a tiny power-up. Serving suggestion: Pair slices with mashed potato or roasted vegetable and a crisp salad to balance the sticky glaze.
Leftovers reheat nicely and also make great sandwiches. Storage: Store in an airtight container in the fridge for up to three days.
Reheat gently in a skillet and add a splash of water to revive the sauce. Small chef trick: Searing in the skillet is optional but recommended—use the skillet to caramelize the outside and you’ll thank me later.
If you love convenience, skip the skillet and still get tasty results in the slow cooker.
