Beef chuck is the part of the steer that extends from the neck area down to the fifth rib, including the shoulder and arm. Though considered to be tough and chewy, beef chuck can be quite delicious if cooked properly. The trick to cooking a beef chuck is doing it slowly so the meat has time to become tender and moist, which will allow for all the flavors to present themselves. Beef chuck is a relatively inexpensive cut of meat that can be braised or used for stews or roasts.
Select a beef chuck roast that has some grains of fat running through it. The more fat that runs through a piece of beef, the more tender it will be when cooked. If a piece of beef is leaner, you run the chance of it being a bit tougher.
Wash your vegetables to prepare them for cooking. You can use any vegetable you like in this recipe, as the above are only suggestions. The vegetables will soak up the juices from the cooking roast and will become more flavorful.
Place your baking bag inside of a large baking dish and place your chuck roast in the center of the bag. Baking bags come in sizes ranging from small to turkey-size. How many vegetables you'll be cooking with the roast will determine which size you should use. If you plan on cooking a bunch of veggies with the roast, you might want to use the turkey-size bag.
Arrange your washed vegetables around the outside of the roast inside of the baking bag. Try to lay your vegetables against the bottom of the bag and don't pile them too high on top of each other. The vegetables on top might not soak up all the juices as they cook.
Sprinkle a package of onion soup mix on top of the roast and the vegetables. Sprinkle some garlic powder and black pepper on top of everything inside of the bag. The soup mix has salt in it, so you won't need to add an additional amount to the meat and veggies. Add approximately 2 cups of water to the inside of the bag.
Seal the bag with the tie that was included in the package. Make three slits in the top of the bag so the steam will be released as the roast is cooking. Place the baking dish inside of a preheated 350-degree oven. Allow the roast to cook for approximately 1 1/2 to 2 hours. When you poke the roast with your finger through the outside of the bag, it should feel tender and give way to the pressure. If the meat is still stiff to the touch, continue cooking the roast. Check the roast for tenderness approximately every 15 to 20 minutes.
Allow the roast to sit in the bag for approximately 15 minutes after it is done. This will allow the juices to set in the roast, making it tender to cut and eat. The meat should almost fall apart when you go to cut it. Use the juice inside of the bag as gravy to pour on your meat and veggies.
Any cut of chuck roast is suitable for this recipe.
