Ingredients

• 1 pork tenderloin (about 1 to 1.25 lb)
• 1 tablespoon olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 tablespoon fresh sage, chopped
• 1 apple, cored and sliced (Honeycrisp or Fuji recommended)
• 1 small onion, thinly sliced
• 2 cloves garlic, minced
• 1/2 cup apple cider (or apple juice)
• 1/4 cup chicken broth
• 1 tablespoon Dijon mustard
• 1 tablespoon brown sugar
• 1 tablespoon cornstarch
• 1 tablespoon cold water
• 1 tablespoon butter
• 1 sprig fresh thyme or extra sage for garnish (optional)

Instructions

1. Pat the pork tenderloin dry and season all over with salt and pepper.
2. If you like neat presentation, tie the tenderloin with kitchen twine so it cooks evenly.
3. Heat the skillet over medium-high heat and add the olive oil.
4. Sear the tenderloin on all sides until the exterior is golden to build flavor.
5. Transfer the seared tenderloin to the crock pot and set aside the skillet.
6. In the same skillet, add a touch more oil if needed and sauté the onion until it softens.
7. Add the garlic and cook briefly until fragrant, stirring with the wooden spoon.
8. Toss the apple slices into the skillet and stir to warm them through.
9. Pour apple cider and chicken broth into the skillet to deglaze, scraping up browned bits with the wooden spoon.
10. Stir in the Dijon mustard, brown sugar, and chopped sage to the skillet mixture so the flavors come together.
11. Pour the apple and onion mixture over the tenderloin in the crock pot.
12. Cover and cook on low until the tenderloin reaches a safe internal temperature, or cook on high for a faster finish.
13. Use the meat thermometer to check doneness and remove the tenderloin when it reaches the target temperature.
14. Let the tenderloin rest on the cutting board while you make the sauce.
15. Spoon the cooking juices from the crock pot into the mixing bowl and skim off excess fat if desired.
16. Whisk together the cornstarch and cold water in the mixing bowl to make a slurry.
17. Bring the reserved juices to a simmer in the skillet and whisk in the slurry until the sauce thickens.
18. Swirl in the butter to add shine and a silky finish to the sauce.
19. Slice the rested tenderloin on the cutting board into medallions.
20. Arrange the sliced pork on the serving platter and drizzle the warm apple sage sauce over the top.
21. Garnish with fresh thyme or extra sage leaves and serve with your favorite sides.

What Else You Should Know

Tip: Searing the tenderloin first creates caramelized bits that make the sauce taste way better. Short sear.

Long flavor. Trust me.

Cooking time: Low in the crock pot gives the best texture.

High works if you’re in a hurry. Use the meat thermometer to aim for the recommended internal temperature for pork and then let the meat rest so juices redistribute.

Apple choice: Firm apples like Honeycrisp or Fuji hold up better in the slow cooker. But if you have a softer apple, the sauce will be sweeter and cozier.

No judgement either way. Sauce hacks: Want a silky-smooth sauce?

Use the immersion blender to puree the onions and apples before thickening. No immersion blender?

Mash a few cooked apple pieces with the back of a spoon. Variations: Swap brown sugar for a drizzle of maple syrup for a deeper flavor.

Use arrowroot instead of cornstarch to keep it gluten-free. You can also switch to a pork loin if you prefer a larger roast—adjust cooking time accordingly.

Serving suggestions: This pork shines with creamy mashed potatoes, roasted Brussels sprouts, or a wild rice blend to soak up the sauce. Add a simple green salad for brightness.

Make-ahead and storage: Sauce stores well in the fridge for a few days. Reheat gently and add a splash of broth if it’s too thick.

Leftover slices are great chilled in sandwiches or warmed for quick lunches. Fun fact: Sage loves pork like peanut butter loves jelly.

The herb cuts through richness and makes every bite feel like a small celebration. Enjoy the slow-cooked ease and the fancy taste.

You did this, and it was almost effortless. Now go impress someone—or just yourself.
