# Instructions:
01 -
Pat your lamb tenderloin super dry with paper towels. This step is crucial for a good sear, honestly, so don’t skip it! Then, sprinkle generously all over with salt and freshly ground black pepper. Feel that beautiful, tender meat; it's going to be so succulent. I always take a moment here to really press the seasonings into the meat, ensuring every inch is ready for flavor.
02 -
Heat a tablespoon of olive oil in a large, heavy-bottomed pan (like a cast iron skillet) over medium-high heat. Once shimmering, carefully place the seasoned lamb in the hot pan. Sear it for about 2-3 minutes per side until it’s beautifully browned all over. This isn't about cooking it through, just building that incredible crust. I once skipped this, and the slow cooker lamb tenderloin was still good, but it missed that deep, rich flavor, you know? Don't be like me that day!
03 -
Remove the lamb from the pan and set aside. Reduce the heat to medium. Add the chopped onion to the pan and cook for 3-5 minutes until it starts to soften and turn translucent, scraping up any browned bits from the lamb – that's flavor gold! Then, toss in the minced garlic and cook for another minute until fragrant. Oh, the smell at this point is just heavenly, it fills the whole kitchen, truly setting the stage for your slow cooker lamb tenderloin!
04 -
Pour in the red wine (if using) and scrape up any remaining delicious browned bits from the bottom of the pan. Let it simmer for a minute or two, letting the alcohol cook off a bit. Then, add the chicken broth, rosemary sprigs, thyme sprigs, and bay leaves. Give it a gentle stir. This liquid is going to become your glorious sauce for the slow cooker lamb tenderloin, so make sure everything is happy in there and smelling wonderful.
05 -
Carefully transfer the seared lamb tenderloin to your slow cooker. Pour the onion, garlic, herb, and liquid mixture from the pan over the lamb. Make sure the lamb is nestled comfortably in the liquid. If it's not mostly submerged, just add a splash more broth. Cover your slow cooker and set it to cook on LOW for 3.5 to 4 hours. Honestly, the hardest part here is the waiting! The anticipation for this slow cooker lamb tenderloin is real.
06 -
Once the cooking time is up, the slow cooker lamb tenderloin should be incredibly tender – it'll practically fall apart with a fork. Carefully remove the lamb from the slow cooker and let it rest on a cutting board for about 10 minutes before slicing. This resting step is super important; it lets the juices redistribute. While it rests, you can skim any excess fat from the sauce in the slow cooker. Slice the lamb against the grain, and serve it with that amazing, flavorful sauce drizzled generously over top. It smells like pure comfort, hon!
# Notes:
01 -
Always pat your lamb tenderloin super dry before searing; it’s the secret to that beautiful crust.
02 -
Store any cooled slow cooker lamb tenderloin and its sauce in an airtight container for up to 3-4 days.
03 -
If you don't have fresh herbs, use 1/3 the amount of dried, but fresh truly elevates the slow cooker lamb tenderloin.
04 -
Serve this slow cooker lamb tenderloin with creamy mashed potatoes to soak up all that amazing sauce!
