Why You’ll Love This Crock Pot Pork Loin

Slow cooking transforms lean pork loin into succulent, flavorful slices everyone craves.

Budget-friendly at about $10-15 for 8 servings, it reheats beautifully for sandwiches or tacos all week.

Ingredients

Gather these basics for the best results. Scale up for larger crowds.

For the Pork and Rub:

• 4-5 lb boneless pork loin (fits most 6-quart crock pots; trim excess fat if needed)
• 3 tsp kosher salt
• 1 tsp black pepper
• 1 tsp garlic powder
• 1 tsp onion powder
• 2 tbsp avocado oil or olive oil (for optional searing)

For the Slow Cooker Base:

• 1/2 cup low-sodium chicken broth
• 1/4 cup soy sauce (use tamari for gluten-free)
• 1 large onion, sliced

For the Honey-Balsamic Sauce:

• 1/4 cup balsamic vinegar
• 3 tbsp honey
• 4 cloves garlic, minced
• 2 tbsp butter

Optional Veggie Add-Ins: 4 carrots and 4 potatoes, chunked (place at bottom for one-pot meal).

Substitutions Table

Make it work with what you have.

Ingredient	Amount	Substitute Option
Pork loin	4-5 lb	Pork shoulder (shreddable)
Balsamic vinegar	1/4 cup	Apple cider vinegar
Soy sauce	1/4 cup	Coconut aminos (low-sodium)
Honey	3 tbsp	Brown sugar or maple syrup

Step-by-Step Instructions

Prep takes 10 minutes. Follow these for foolproof tenderness.

1. Prep the Base: Add chicken broth, soy sauce, sliced onion (and veggies if using) to your crock pot. Stir to combine.
2. Make the Rub: Mix salt, pepper, garlic powder, and onion powder in a small bowl. Pat pork loin dry, then rub seasoning all over, including under any fat cap.
3. Sear for Flavor (Optional but Recommended): Heat oil in a large skillet over medium-high. Sear pork 3 minutes per side until golden. This creates a flavorful crust via the Maillard reaction.
4. Assemble and Cook: Whisk balsamic vinegar, honey, and garlic. Place pork fat-side up in crock pot. Brush with half the sauce mixture. Pour remaining sauce around it. Cover and cook on LOW 6-8 hours or HIGH 3-4 hours, until internal temp hits 145°F (use a meat thermometer in thickest part).
5. Finish the Sauce: Transfer pork to a platter; tent with foil to rest 10-15 minutes (juices redistribute for moistness). Whisk butter into crock pot liquids over stovetop (or on warm setting if removable insert). Simmer 2-3 minutes to thicken. Taste and adjust salt/pepper.

Slice against the grain. Serve with sauce spooned over top.

Cooking Time Guide

Times vary by size and model. Always verify with thermometer.

Pork Size	LOW	HIGH	Check Temp
3-4 lb	5-7 hrs	2.5-3.5 hrs	145°F
4-5 lb	6-8 hrs	3-4 hrs	145°F
Frozen	+2 hrs	Not recommended	145°F

Pro Tips for Perfection

Slow cooking breaks down collagen into gelatin for that melt-in-mouth texture. Keep lid closed to trap moisture. Fat-side up bastes the meat naturally. Resting prevents dry slices. Avoid overcooking: pork dries above 160°F. For extra veggies, layer at bottom; they absorb flavors.

Serving Suggestions

Pair with creamy mashed potatoes, roasted asparagus, or green beans. For low-carb, try cauliflower mash or zucchini noodles. Drizzle sauce over everything.

• Classic: Sliced pork + gravy + dinner rolls.
• Salad: Thin slices over greens with apple vinaigrette.
• Wraps: Shred leftovers in tortillas with coleslaw.

This recipe shines as meal prep. Store slices and sauce separately in airtight containers.

• Fridge: 3-4 days. Reheat gently in microwave or 350°F oven with broth splash.
