Here's my favorite slow cooker recipe. It's from Nom Nom Paleo, and it changed the way I think about slow cookers. (I always thought of them as big bathtubs of food, very liquid-forward.)
Ingredients: beef brisket, kosher salt and smoked paprika
Lay beef brisket in the slow cooker. Season liberally with salt and smoked paprika. (Smoked paprika is a staple in my house, if I didn't have it, I think I'd sub chili powder and cumin to try to get a smoky taste.)
Cook on slow for 8 hours or so.
NO LIQUID! You get brisket cooked to a deliciously ropey, falling-apart texture. Miraculously, it is not dry. The hardest part of this recipe is going to the store and getting a brisket. I find that challenging sometimes.
