07 - 1 tbsp Dijon mustard
08 - 4-5 cloves garlic, minced

11 - Black pepper, to taste

12 - 1-2 tbsp olive oil

# Instructions:

01 - First things first, let's get that lamb ready. Pat your lamb tenderloin really, really dry with paper towels. This step is crucial for getting a good sear, which locks in all those wonderful juices. Don't skip it, even if you're in a hurry—I've made that mistake, and the lamb just sort of steams instead of searing, which isn't what we're after. Season it generously with salt and pepper all over. You want a nice even coating, almost like a crust, before it even hits the pan.
02 - Now, grab a large skillet and heat a tablespoon or two of olive oil over medium-high heat. Once it's shimmering, carefully place your seasoned lamb tenderloin in the pan. Sear it for about 2-3 minutes per side, just until it's beautifully browned all over. You're not cooking it through, just building that fantastic flavor and color. The kitchen will start to smell amazing right about now, a preview of what's to come! This is where I almost always burn myself a little, so be careful with the splatters!
03 - Time to get the slow cooker involved! Scatter your chopped potatoes, carrots, and onion evenly across the bottom of your crockpot. This creates a lovely bed for the lamb to rest on and ensures the veggies absorb all those rich flavors. I like to spread them out so they cook evenly, rather than clumping up in one spot. It’s a simple step, but it makes a difference in the final texture of your veggies.
04 - Next, in a bowl, whisk together the beef broth, Worcestershire sauce, Dijon mustard, and minced garlic. Pour this savory mixture over the vegetables in the slow cooker. Make sure everything is nicely coated. This liquid is going to transform into a delicious, rich sauce as it simmers with the lamb. It's the magic potion that makes this dish so incredibly tender and flavorful.
05 - Carefully place your seared lamb tenderloin on top of the vegetables in the crockpot. Sprinkle the dried rosemary over the lamb. Give it a gentle pat to make sure the seasoning adheres. The lamb should be nestled comfortably amongst the veggies. This setup ensures that as the lamb cooks, its juices will mingle with the broth and vegetables, creating a symphony of flavors.
06 - Cover your crockpot and set it to cook on low for 4-6 hours, or on high for 2.5-3.5 hours. The cooking time for this Crockpot Lamb Tenderloin can vary a bit depending on your slow cooker, so keep an eye on it. The lamb is done when it's fork-tender and easily pulls apart. Honestly, the smell filling your home will be the best indicator that something wonderful is happening! When it’s ready, I like to let it rest for a few minutes before slicing or shredding.

# Notes:

01 - Searing the lamb before slow cooking adds a crucial layer of flavor you won't get otherwise.
02 - Leftovers keep well in an airtight container in the fridge for 3-4 days, but reheat gently to maintain tenderness.
03 - If you don't have Dijon, a tiny splash of apple cider vinegar can give a hint of tang, but it's not a direct swap.
04 - Serving this with a side of crusty bread to soak up all that incredible sauce is an absolute must for me!
