I have a fun recipe for you this week- Slow Cooker Roasted Garlic Beef Sandwiches. I joined a fun group where we all get assigned to try a recipe from a fellow blogger, and it is all kept secret until today. I got to pick a recipe from Aunt Bee’s Recipes. Brandi from Aunt Bee’s Recipes is a dear friend, and she also loves her crockpot as much as I do!

How could you go wrong with beef, roasted garlic and beer? There is a small amount of prep work with roasting the garlic but it really is simple once you get started.

How to roast a head of garlic:

  • Preheat the oven to 350 degrees
  • Cut the top of the garlic off, exposing the cloves.
  • Drizzle over a touch of oil.

  • Cover tightly with foil. Place in oven, I put it right on the rack.
  • Let the garlic roast for 1 hour.
  • Remove and let cool for about 20 minutes before handling.

How to make Roasted Garlic Roast Beef Sandwiches:

  • Add a chuck roast to the slow cooker.
  • Press brown sugar onto the roast.
  • Sprinkle with salt, pepper and onion powder.
  • Pour liquid smoke and beer around the roast.
  • Squeeze the garlic bulbs out of the head of garlic on to the roast.

How long do I cook?

  • Place the lid on the slow cooker.
  • Cook on LOW for 8-10 hours without opening the lid during the cooking time.

How do I serve these sandwiches?

  • Shred the beef with 2 forks right in the slow cooker.
  • Pile the meat on buns and add a slice of cheese, swiss or white cheddar is great!
