Equipment: Must-haves

• Crock pot (slow cooker)
• Cutting board
• Chef’s knife
• Tongs
• Measuring spoon
• Measuring cup
• Small bowl

Equipment: Nice-to-haves

• Skillet (for searing)
• Meat thermometer
• Slotted spoon
• Basting brush

Ingredients

• 1 pork tenderloin (about 1 to 1.25 lb)
• 1 tablespoon olive oil (for searing, optional but recommended)
• 1 medium onion, thinly sliced
• 2 clove garlic, minced
• 1/2 cup whole-berry cranberry sauce (or fresh cranberries with a bit of sugar)
• 1/4 cup pure maple syrup
• 2 tablespoon Dijon mustard
• 1 tablespoon soy sauce (or tamari for gluten-free)
• 1/2 teaspoon dried thyme
• 1/4 teaspoon black pepper
• 1/2 teaspoon salt (adjust to taste)
• 1 tablespoon apple cider vinegar (brightens the sauce)
• 1 teaspoon cornstarch (optional, for thickening)
• 1 tablespoon water (for mixing cornstarch, optional)
• Fresh parsley for garnish (optional)

Instructions

1. Pat the pork tenderloin dry and season lightly with salt and pepper.
2. If you like a golden crust, heat a skillet with oil and sear the tenderloin on all sides until browned; this step is optional but tasty.
3. Place the sliced onion in the bottom of the crock pot to form a flavorful bed.
4. Set the seared or unseared tenderloin on top of the onion in the crock pot.
5. In a small bowl, whisk the maple, cranberry sauce, Dijon mustard, soy sauce, minced garlic, dried thyme, apple cider vinegar, and a pinch of pepper until smooth.
6. Pour the sauce evenly over the tenderloin and onions so everything gets cozy and covered.
7. Cover and cook on low until the tenderloin reaches the correct internal temperature, or cook on high if you’re short on time.
8. If the sauce looks thin near the end, mix cornstarch with water to make a slurry and stir it into the crock pot; let it cook briefly until the sauce thickens.
9. When the tenderloin is done, transfer it to a cutting board and let it rest so the juices settle.
10. Slice the tenderloin against the grain into medallions.
11. Spoon the cranberry-maple-onion sauce over the sliced pork and garnish with fresh parsley if you want to look fancy.
12. Serve with mashed potato, roasted vegetable, or a simple green salad to soak up that glorious sauce.

Good to Know

Tip: Searing is optional but it adds a caramelized flavor and prettier color. If you skip searing, your crock pot will still make a tender, delicious pork tenderloin.

Timing: Cook on low for several hours for the most tender results, or on high for a faster finish. Use a meat thermometer to check for the safe internal temperature; remove the pork slightly before it reaches the target temperature because it will keep cooking while resting.

Sauce notes: Whole-berry cranberry sauce creates texture and pops of tartness. If you prefer smooth, pulse the sauce with a fork or blend briefly.

Want a thicker glaze? Make a cornstarch slurry and stir it in toward the end.

Flavor swaps: Swap the Dijon for grainy mustard for extra texture, or add a splash of balsamic for depth. For a spicy kick, stir in a little red pepper flakes or a dash of hot sauce.

Serving suggestion: This dish pairs well with creamy mashed potato, buttered noodle, or roasted root vegetable. Leftovers keep well and make excellent sandwiches or salads the next day.

Storage: Refrigerate the cooled pork and sauce in an airtight container for up to four days. Reheat gently to avoid drying out the meat.

Freeze portions for longer storage. That’s why this recipe is a kitchen win: low effort, big flavor, and a crowd-pleasing combo of maple, cranberry, and onion that makes a single pork tenderloin feel like a holiday feast.

Enjoy, and try not to eat the sauce straight from the spoon (I mean, you can, but don’t blame me).
