Contents
Equipment: Must-haves
- Slow cooker (crock pot)
- Skillet (for searing)
- Cutting board
- Chef’s knife
- Measuring spoons and measuring cup
- Small bowl (for sauce mix)
- Tongs or spatula
- Wooden spoon or whisk

Equipment: Nice-to-haves
- Meat thermometer (to check doneness)
- Kitchen twine (to keep the tenderloin neat)
- Immersion blender or blender (to smooth the sauce)

Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb)
- 1 apple, cored and sliced thin
- 1 small onion, thinly sliced
- 1 clove garlic, minced
- 1/4 cup apple juice
- 1/4 cup pure maple syrup
- 1 tbsp Dijon mustard
- 1 tbsp olive oil
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp dried thyme or 1 tsp fresh thyme, chopped
- 1 bay leaf
- 1 tbsp cornstarch
- 2 tbsp cold water (for slurry)
- 1 tbsp unsalted butter (optional, for glossy sauce)
- Fresh parsley, chopped (for garnish)

Instructions
- Pat the pork tenderloin dry and season it lightly with salt and pepper on all sides.
- Heat the skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the pork on all sides until golden brown to lock in juices, then transfer it to the plate.
- Place the sliced apple and onion in the bottom of the slow cooker to make a cozy bed for the meat.
- Nestle the seared pork on top of the apple and onion so it soaks up that flavor.
- In the small bowl, whisk together the apple juice, maple syrup, Dijon mustard, minced garlic, thyme, salt, pepper, and the bay leaf.
- Pour the apple-maple mixture over the pork and apples, making sure the sauce reaches the meat.
- Cover the slow cooker and cook on low until the pork is tender and reaches a safe internal temperature.
- Check the pork with the meat thermometer near the thickest part; when it reads done, remove the pork to a plate and let it rest.
- Strain the cooking liquid into the skillet or a saucepan, discarding the bay leaf and any large bits you don’t want in the sauce.
- Bring the sauce to a gentle simmer and whisk in the cornstarch slurry until it thickens to a glossy consistency.
- If you want a super-smooth sauce, use the immersion blender carefully or transfer to a blender and pulse until smooth.
- Swirl in butter at the end for extra gloss and richness if desired.
- Slice the rested pork into medallions and spoon the warm apple-maple herb sauce over the top.
- Garnish with fresh parsley and serve with your favorite side, making sure to spoon extra sauce on each plate.

What Else You Should Know
Tips: Searing the pork first gives you a better crust and more flavor, even though the slow cooker does the long work. Timing: Cook time varies by slow cooker and tenderloin size; aim for low and slow until tender rather than guessing.
Using a meat thermometer helps avoid overcooking. Sauce notes: If the sauce seems thin, simmer it a bit longer uncovered to reduce, or thicken with the cornstarch slurry.
For a smoother finish, blend the sauce and add a small knob of butter for shine. Variations: Swap the apple for pear if you like a different sweetness.
Add a splash of apple cider vinegar for brightness. For a savory boost, stir in a spoonful of soy sauce or Worcestershire sauce to the glaze.
Serving suggestions: Serve the sliced pork with mashed potatoes, roasted vegetables, or a simple grain. A green salad with a tangy vinaigrette cuts through the sweetness nicely.
Make-ahead: You can cook the tenderloin, cool it, and refrigerate the meat and sauce separately for up to two days. Reheat gently and spoon warmed sauce over slices.
Health note: Pork tenderloin is a lean cut and pairs well with fruit-forward glazes that keep dishes bright without extra fat. Using pure maple syrup gives a real maple flavor without processed syrups.
Final thought: This is a hands-off dinner that still looks like you spent effort. That’s why busy weeknights and casual dinner guests will both be impressed.
