Slow Cooker Onion Lover’s Pork Loin

August 14, 2025 By Grumpy

Servings: 3–4 | Cook Time: 4–6 hours (low) or 2.5–3.5 hours (high)

Ingredients

  • 1 lb pork loin

  • 1 Tbsp olive oil (optional for searing)

  • 1/4 cup Onion Soup Mix (or one packet of store brand equivalent)

  • 1 medium yellow onion, thinly sliced

  • 1 cup beef broth (or chicken broth for milder flavor)

  • 1 tsp garlic powder

  • ½ tsp black pepper

  • 1 Tbsp Worcestershire sauce

  • 1 Tbsp butter

  • Optional: ½ cup sliced mushrooms for extra savory flavor


Instructions

  1. Optional Sear: Heat olive oil in a skillet over medium-high heat. Sear the pork loin for 2–3 minutes per side until golden brown. This deepens the flavor.

  2. Layer the Onions: Place sliced onions in the bottom of your slow cooker.

  3. Season & Arrange: Place pork loin on top of onions. Sprinkle garlic powder, pepper, and the entire packet of onion soup mix over the pork.

  4. Add Liquids: Pour broth and Worcestershire sauce around (not over) the pork to keep seasoning in place.

  5. Butter Boost: Place the butter on top of the pork.

  6. Cook:

    • Low: 4–6 hours (juiciest)

    • High: 2.5–3.5 hours
      Pork is done when it reaches 145 °F internal temp, then rest 5–10 minutes before slicing.

  7. Serve: Spoon the onion-rich juices over the sliced pork. Excellent with mashed potatoes or crusty bread to soak up the sauce.


Extra Onion Flavor Boost (Optional)

  • Add 1–2 tsp onion powder along with the soup mix.

  • Use two onions instead of one.

  • Replace ½ cup of the broth with French onion soup for a deeper, sweeter onion note.
