First things first, pat your chuck roast cubes super dry with paper towels. This is crucial for a good sear, trust me on this! Heat a couple tablespoons of olive oil in a large skillet over medium-high heat until shimmering. Add the beef in batches, don't overcrowd the pan, or it'll steam instead of sear. Brown each side until it's lovely and golden-brown, about 2-3 minutes per side. You want that gorgeous crust; it adds so much flavor to your Slow Cooker Garlic Butter Beef. Transfer the seared beef to your slow cooker.

In the same skillet (don't clean it, those browned bits are flavor gold!), melt the unsalted butter over medium heat. Add your minced fresh garlic and sauté it for about 1 minute until it's fragrant and just starting to turn golden. Oh, the smell, honestly, it's intoxicating! This is where the magic really starts for your Slow Cooker Garlic Butter Beef. Pour in the beef broth and Worcestershire sauce, scraping up all those delicious brown bits from the bottom of the pan. Let it simmer for a minute, then pour this amazing liquid over the seared beef in the slow cooker.

Now for the seasonings! Sprinkle the dried thyme, salt, and black pepper over the beef and liquid in the slow cooker. Give it a gentle stir to combine everything. Pop the lid on, set it to low for 6-8 hours or high for 3-4 hours. I usually go for low if I'm leaving the house; it just makes the beef extra tender and gives the flavors more time to meld. The house will smell incredible as this Slow Cooker Garlic Butter Beef cooks, I promise!

Once the beef is fall-apart tender, carefully remove it from the slow cooker and set it aside. In a small bowl, whisk together the cornstarch with a few tablespoons of cold water until you have a smooth slurry. Pour this slurry into the liquid remaining in the slow cooker. Stir it in well, then turn the slow cooker to high (or even the "sauté" function if yours has it) and let the sauce simmer, stirring occasionally, until it thickens to your desired consistency. This usually takes about 10-15 minutes. It should coat the back of a spoon beautifully!

Once the sauce is thick and glossy, return the tender beef back to the slow cooker. Give it a gentle stir to coat all those glorious pieces of Slow Cooker Garlic Butter Beef in the rich sauce. Taste and adjust any seasonings if needed. Sometimes I add a tiny pinch more salt or pepper here. I've been known to sneak a little taste (or two!) at this point, it's just so good. This step just brings everything together, making sure every bite is infused with that incredible garlic butter flavor.

Ladle generous portions of your Slow Cooker Garlic Butter Beef onto plates. Before serving, sprinkle generously with fresh chopped parsley. That little bit of green and fresh herb really brightens up the dish and adds a lovely contrast. It just makes it feel a bit fancy, even though it was so easy! Serve it hot with your favorite sides. The beef should be so tender you can cut it with a fork. Honestly, it's a showstopper without the effort!
