I didn't expect that it would become a staple, filling the house with the most incredible sweet and savory aroma. It’s a hug in a bowl, every single time.

I remember the first time I made this Slow Cooker Apple Butter Lamb Tenderloin, I accidentally added a bit too much apple butter oops!

Slow Cooker Apple Butter Lamb Tenderloin - Ingredients

Lamb &, Aromatics

  • Lamb Tenderloin: This cut is so tender, it practically melts! Use good quality lamb, honestly, it makes all the difference. I usually grab two smaller ones, about 1-1.5 lbs each.
  • onion: A trusty base for any slow cooker dish. It mellows out and adds a lovely sweetness. I usually go for a yellow onion, roughly chopped.
  • garlic: You can never have too much garlic, in my opinion! Freshly minced is key here, don't even think about the jarred stuff.

Sweet &, Savory Sauce

  • Apple Butter: The star of the show for this Slow Cooker Apple Butter Lamb Tenderloin! It brings that deep, sweet, spiced fruit flavor. I've tried making my own, but store-bought is perfectly fine.
  • Dijon Mustard: This adds a little tang and cuts through the richness of the lamb and sweetness of the apple butter. I once used yellow mustard by mistake... it was a learning experience.
  • Apple Cider Vinegar: Just a splash brightens everything up. It's a non-negotiable for balancing the flavors.

Flavor Enhancers

  • Chicken Broth: Needed to create that luscious sauce. Low sodium is my preference so I can control the salt myself.
  • fresh rosemary: Its earthy, piney notes are just magical with lamb. Don't skimp on this! I love the smell of it as it steeps in the sauce.
  • Salt and Black Pepper: Seasoning is everything, folks! Season the lamb well before it goes into the slow cooker.

Garnish &, Serve

  • Fresh Parsley: A sprinkle at the end for freshness and a pop of color.

Making Slow Cooker Apple Butter Lamb Tenderloin

Sear the Lamb:
First things first, get those lamb tenderloins browned. Pat them super dry with paper towels this is crucial for a good sear! Heat a tablespoon of olive oil in a heavy skillet over medium-high heat until it’s shimmering. Sear the lamb for 2-3 minutes per side until it's beautifully golden brown. This step, while optional, truly locks in flavor and texture, don't skip it, I promise you won't regret it. It smells amazing already, trust me!
Build the Base:
Once the lamb is seared, remove it from the skillet and set aside. Toss in your chopped onion and let it soften for a few minutes, scraping up any browned bits from the bottom of the pan that’s flavor right there! Then, add the minced garlic and cook for another minute until fragrant. This is where the kitchen starts to smell absolutely divine, honestly. I've definitely burned the garlic once or twice getting distracted, so keep an eye on it!
Whisk the Sauce:
In a bowl, whisk together the apple butter, Dijon mustard, apple cider vinegar, and chicken broth. Make sure it's all smooth and well combined. This is the liquid gold that will transform your lamb into the most tender, flavorful Slow Cooker Apple Butter Lamb Tenderloin. I usually give it a little taste test here a tiny bit, just to make sure it's hitting all the right notes!
Slow Cooker Assembly:
Place the seared lamb tenderloins into your slow cooker. Sprinkle with fresh rosemary, a good pinch of salt, and a generous crack of black pepper. Pour the whisked apple butter sauce mixture over the lamb. Make sure the lamb is mostly submerged or at least well coated. This step is super straightforward, no real room for error, which I appreciate on busy days.
Set It and Forget It:
Cover your slow cooker and cook on low for 4-6 hours, or on high for 2-3 hours. The cooking time for Slow Cooker Apple Butter Lamb Tenderloin can vary depending on your slow cooker and the thickness of your lamb. The lamb should be fork-tender and practically falling apart. Don't peek too much, every time you lift the lid, heat escapes and slows down the cooking process. I learned that the hard way, thinking I was helping!
Rest and Serve:
Once cooked, carefully remove the lamb from the slow cooker and let it rest on a cutting board for about 10 minutes before slicing or shredding. This allows the juices to redistribute, keeping the lamb moist and tender. Give the sauce a good stir, it might have thickened up beautifully. Garnish with fresh parsley before serving. The aroma by now is just intoxicating, signaling a truly delicious Slow Cooker Apple Butter Lamb Tenderloin is ready!

Making this Slow Cooker Apple Butter Lamb Tenderloin always brings a sense of calm to my kitchen, even amidst the usual flour dust and stray herb bits.

Slow Cooker Apple Butter Lamb Tenderloin Storage Tips

This Slow Cooker Apple Butter Lamb Tenderloin is fantastic for leftovers, maybe even better the next day! Once cooled, transfer the lamb and its sauce to an airtight container. It’ll keep beautifully in the fridge for 3-4 days. I've reheated it gently on the stovetop or in the microwave, just be careful not to overcook the lamb, or it can get a bit tough. I microwaved it once on high, and the sauce separated a little so don't do that, lol. If freezing, make sure the lamb is completely cooled, then portion it out with plenty of sauce into freezer-safe bags or containers. It’ll last for up to 3 months. Thaw overnight in the fridge before reheating. It's a meal-prep dream, honestly.

Slow Cooker Apple Butter Lamb Tenderloin Substitutions

Life happens, and sometimes you don't have exactly what the recipe calls for. For the lamb tenderloin, if you can't find it, pork tenderloin is a really good swap I've tried it, and it works wonderfully, just adjust cooking time slightly. No apple butter? You could use applesauce mixed with a teaspoon of pumpkin pie spice and a tablespoon of brown sugar, but it won't have the same depth, I tried it once, and it worked... kinda, but apple butter is truly the star. If fresh rosemary isn't available, a teaspoon of dried rosemary will do, but fresh really makes this Slow Cooker Apple Butter Lamb Tenderloin sing. Don't have apple cider vinegar? White wine vinegar or even a squeeze of lemon can offer that needed tang.

Frequently Asked Questions

→ Can I use a different cut of lamb for this Slow Cooker Apple Butter Lamb Tenderloin?

You totally can! While tenderloin is my go-to for its melt-in-your-mouth texture, lamb shoulder or even a boneless leg of lamb cut into chunks would work. Just be prepared for a longer cooking time to get that fork-tender result. I've used shoulder for a heartier stew, and it's delicious!

→ What if I don't have apple butter on hand?

If you're in a pinch, you can try combining applesauce with some brown sugar, cinnamon, and a tiny bit of allspice. It won't have the same concentrated depth as true apple butter, but it'll get you in the ballpark. I've done it, and it works, but the real deal is always better for this Slow Cooker Apple Butter Lamb Tenderloin.

→ My sauce seems too thin after cooking, what happened?

Sometimes slow cooker sauces can be a bit thin because there's no evaporation. Don't fret! Just carefully transfer the sauce to a saucepan on the stovetop and simmer it over medium-high heat for 10-15 minutes, stirring occasionally, until it reduces and thickens to your liking. I've had to do this many times!

→ How long can I keep leftovers of this Slow Cooker Apple Butter Lamb Tenderloin?

Leftovers are a gift! Store any remaining lamb and sauce in an airtight container in the fridge for up to 3-4 days. It tastes even better the next day as the flavors really meld. I've definitely forgotten about it once and found it still delicious on day 4, but stick to the guidelines for safety!

→ Can I add vegetables directly to the slow cooker with the lamb?

Absolutely! Heartier vegetables like carrots, potatoes, or parsnips would be fantastic. Add them about 2-3 hours before the end of the cooking time so they don't turn to mush. I often throw in some baby carrots, and they soak up all that amazing sauce!
