Tip: From Frozen Tender RoastCover it and put in the oven on low (I put it on at 250 degrees F). I normally put my roast in the oven at 3:00 pm and cook it until supper time at 7:00 pm. When you cook it frozen at a low temp for at least 4 hours, the roast will be the tenderest. You can cut it with a fork!

In the refrigerator, ground beef, stew meat, and steaks may thaw within a day. Bone-in parts and whole roasts may take 2 days or longer. Once the raw ground beef thaws, it will be safe in the refrigerator for 1 to 2 days. All other cuts of beef can be refrigerated safely for 3 to 5 additional days before cooking.

If your bones (and meat) are frozen, thaw them before beginning. Put the bones into a baking dish or roasting pan that is at least an inch deep. Place them, uncovered, into a 400 degree oven for 45 minutes to an hour, or until the bones are nicely browned.
Whether it's beef, chicken or pork, cooking frozen meat in a slow cooker can cause it to spend too much time at a temperature at which dangerous bacteria can grow, no matter what temperature it gets to eventually. According to the USDA, you should always thaw meat before slow cooking it.
According to their Slow Cookers and Food Safety guidelines, you should always thaw meat or poultry before putting it in a slow cooker. They recommend storing the thawed meat in the refrigerator before adding it in.
Allow 12 to 24 hours to defrost steaks, depending on thickness. Allow 4 to 7 hours per pound to defrost large roasts or thick compact pot roasts. Allow 3 to 5 hours per pound to defrost small roasts or thin pot roasts.
Place the meat in a microwave-safe dish. Rotate, break apart or turn food items during defrosting to even the thawing. Cook meat, poultry, egg casseroles, and fish immediately after defrosting in the microwave oven because some areas of the frozen food may begin to cook during the defrosting time.
Leaving Frozen Meat OutFrozen meat should not be left out for more than two hours, advises the U.S. Department of Agriculture. Meat can be cooked from frozen, although not in the slow cooker -- just increase the cooking time by about 50 percent. Alternatively, defrost the meat before cooking it.
Place the wrapped meat in a large bowl and fill with cold water. Change the water every 30 minutes as the meat continues to thaw. A 1-pound package of meat can thaw in an hour or less. Packages of 3 to 4 pounds can take more than two hours.
As long as the steak is covered, you can allow it to defrost naturally at room temperature. It will take between 6–10 hours depending on the type and thickness of the steak. Once fully defrosted and up to room temperature, you can cook as normal. If you defrost at room temperature, be extra careful when cooking.
Searing meat is an essential step if you want to make the most flavorful roasts, steaks, chops, and more. When you sear meat, you caramelize the natural sugars in the meat and brown the proteins, forming a rich brown crust on the surface of the meat that amplifies the savory flavor of the finished dish.
