- Measuring cups and spoons
- Small bowl
- Whisk or fork
- Tongs

Equipment: Nice-to-haves
- Cast-iron skillet (for searing, optional)
- Instant-read thermometer (very useful)
- Silicone brush (for basting, optional)
- Sauté pan (for caramelizing onion, optional)

Ingredients
- 1 pork tenderloin (about 1 to 1¼ pound)
- 1/2 cup apple butter
- 2 tablespoons Dijon mustard
- 1 tablespoon soy sauce
- 1 tablespoon brown sugar (optional, for extra caramel)
- 1 tablespoon fresh sage, chopped
- 3 cloves garlic, minced
- 1 small onion, thinly sliced
- 1/4 cup chicken broth
- 1 tablespoon apple cider vinegar
- 1 tablespoon olive oil
- Salt to taste
- Black pepper to taste
- Fresh sage leaf for garnish (optional)
- Note: Use a low-sugar apple butter if you prefer less sweetness, and fresh sage for the brightest flavor.

Instructions
- Pat the pork tenderloin dry on the cutting board and trim any silver skin with the knife.
- Season the tenderloin all over with salt and black pepper.
- If you like a browned exterior, heat the cast-iron skillet with olive oil and sear the tenderloin on all sides until golden using tongs.
- Place the sliced onion in the bottom of the Crock Pot to form a flavorful bed for the tenderloin.
- Whisk apple butter, Dijon mustard, soy sauce, brown sugar, minced garlic, chopped sage, apple cider vinegar, and chicken broth together in the small bowl.
- Pour half of the sauce into the Crock Pot over the onions, reserving the rest for basting and finishing.
- Nestle the tenderloin on top of the onions in the Crock Pot.
- Pour the remaining sauce over the tenderloin so it gets cozy in all that flavor.
- Cover the Crock Pot and cook on low or high depending on your schedule; choose the slow option for more tenderness and time for flavors to mingle.
- About halfway through cooking, open the Crock Pot and baste the tenderloin with the reserved sauce using the silicone brush or a spoon.
- If you caramelized onions separately in the sauté pan, add them back to the Crock Pot now to soak up the sauce.
- Use the instant-read thermometer to check the internal temperature of the tenderloin for doneness.
- When the tenderloin reaches a safe and juicy temperature, remove it from the Crock Pot and let it rest covered on the cutting board.
- Slice the pork against the grain on the cutting board and spoon warm sauce and onions over the slices.
- Garnish with a fresh sage leaf and serve with your favorite sides or a simple grain to soak up the sauce.

What Else You Should Know
Tips for success:
Letting the pork rest after cooking is non-negotiable — that short pause keeps the meat juicy and avoids sad, dry slices. If you sear the tenderloin, you’ll lock in flavor and create a nice color contrast — it’s optional, but worth the tiny bit of effort.
Timing note: Cook low for a relaxed schedule so the flavors marry and the pork becomes tender, or cook high if you’re short on time; both work but low is more forgiving. Variations you’ll love:
Swap the soy sauce for tamari or leave it out for a gluten-free version, and try adding a splash of apple brandy to the sauce for a grown-up twist.
If you want a herb-forward profile, stir a little rosemary into the sauce, but don’t steal the spotlight from the apple butter and sage — they’re the stars. Serving suggestions:
Serve sliced tenderloin with roasted root vegetables, creamy mashed potato, or a warm grain like farro for a modern, comforting plate.
For a lighter plate, pair with a crisp green salad dressed in lemon and olive oil to cut the sweetness. Make-ahead and storage:
You can assemble the sauce and slice the onion ahead of time and refrigerate them separately for a day; add to the Crock Pot when ready to cook.
Store leftovers in an airtight container in the fridge for up to three days and reheat gently to avoid drying out the pork. Leftovers make a fabulous sandwich or salad topper — the sauce plays well with everything.
Health and trend notes:
This recipe nods to current trends of time-saving slow-cooker cooking and balanced sweetness instead of sugar-overload; using moderate-sugar apple butter keeps it modern and mindful. Final quip: You’re essentially cheating at dinner in the best possible way — set it, forget it, and then impress everyone with minimal drama.
