Yes, you sure can! First, sear the meat in a skillet. Once that's done, add the cooked meat and vegetables into the slow cooker, and pour all the broth and aromatic ingredients on top (minus the flour). Let this cook on low for about 7 to 8 hours or on high for 4 to 5 hours. Lastly, mix the flour with some water and mix it into the slow cooker until the sauce thickens up a bit.
