Why This Recipe Works So Well

- Searing the meat first to lock in a rich, golden crust that infuses the entire broth as it cooks low and slow
The result is a beef roast in slow cooker that tastes like it came from a Sunday restaurant kitchen, not a weeknight home oven.
Chef's Tip: Do not skip the sear. Even if you are short on time, those 8 minutes in a hot skillet add a depth of flavor that slow cooking alone simply cannot replicate.
The Right Tools Make This Even Easier

Tender Beef Loin Crockpot Roast with Potatoes and Carrots
This fall-apart tender beef loin crockpot roast is the ultimate set-it-and-forget-it dinner, loaded with hearty potatoes, carrots, and rich savory broth. The easiest slow cooker beef roast you will ever make.
Ingredients
- 3 lb beef loin roast, trimmed of excess fat
- 1 1/2 lb baby potatoes, halved if large
- 4 carrots, peeled and cut into 2-inch chunks
- 1 yellow onion, roughly chopped
- 5 garlic cloves, smashed
- 1 cup beef broth, low sodium preferred
- 2 tbsp Worcestershire sauce
- 2 tbsp tomato paste
- 2 tbsp olive oil, for searing
- 1 tsp dried rosemary
- 1 tsp dried thyme
- 1 tsp smoked paprika
- 1 1/2 tsp kosher salt, or to taste
- 1 tsp black pepper, freshly ground
- 2 tbsp cornstarch, optional, for thickening the gravy
Instruction
Pat the beef loin roast completely dry with paper towels. In a small bowl, mix together the salt, pepper, smoked paprika, rosemary, and thyme. Rub the spice mixture all over the roast, pressing it into the surface.
Heat the olive oil in a large skillet or cast iron pan over medium-high heat until shimmering. Sear the roast for 3 to 4 minutes per side until a deep brown crust forms. Do not skip this step as it builds the foundation of flavor.
While the roast sears, place the chopped onion, smashed garlic, baby potatoes, and carrot chunks in the bottom of a 6-quart or larger slow cooker.
In a small bowl, whisk together the beef broth, Worcestershire sauce, and tomato paste. Pour the mixture over the vegetables in the slow cooker.
Nestle the seared beef loin roast on top of the vegetables. Spoon some of the liquid over the top of the roast.
Place the lid on the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the beef is fork-tender and easily pulls apart.
Once done, carefully transfer the roast and vegetables to a serving platter and tent with foil. If you would like a thicker gravy, pour the remaining liquid from the slow cooker into a small saucepan over medium heat. Whisk the cornstarch with 2 tablespoons of cold water, then stir into the liquid. Simmer for 3 to 5 minutes until thickened.
Slice or shred the beef roast and serve over the potatoes and carrots with the gravy drizzled on top.
