Marinated London Broil Slow Cooker - If you would like to marinate beforehand (suggested to do the night before) add the following ingredients above into a gallon freezer bag. Add meat, seal, lay flat in fridge for 2 hours to overnight. Then follow steps below after taking meat out of bag.
Add beef to slow cooker. Add broth around the meat. Spread oregano, basil, salt and pepper on top of the meat. Sprinkle minced garlic on top of spices.
Pour condensed soup on top of the meat, spread out over the top to cover and keep moist. Cover the slow cooker and heat on low for 6 hours. (timing will depend on thickness of your meat but you want it to be medium-rare at 130F in the thickest part)
Remove and slice AGAINST the grain for tender slices. Serve with gravy from pot poured over the top.
