Place carrots in a single layer in a 5-qt. slow cooker.

The Art of Browning Browning meats and poultry before simmering in the slow cooker yields major depth of flavor plus a picture-perfect presentation, so don't be tempted to skip it. First, pat the meat dry with paper towels before seasoning. Set a heavy stainless-steel or well-seasoned cast-iron skillet (not nonstick) over medium to medium-high heat for 2 to 3 minutes or until hot enough for the oil to shimmer--the meat should hiss and sizzle as soon as it hits the pan. Be sure not to crowd the pan; doing so drops the temp, causing the meat to steam rather than form a crisp crust. Don't turn the meat until the bottom is well-browned.
