In your crockpot or cast iron skillet on the stove. Cut the butter into slices, add a few pieces in to start melting. Season your room temperature roast on one side with half the seasonings and 1 packets of Lipton soup mix, cut slices and stuff in garlic cloves. Place face down on top of the melting butter and let it sear until browned. Season and stuff with garlic on the other side. And flip to sear the other side.
Once your meat is done, turn crockpot to high for 4 hours or low for 8. Add your meat, gravy jar, add water to jar after and shake it up and pour in. Add mushroom soup, cover and cook!!
