Slow Cooker Pot Roast

Prep: 15 mins

The slow cooker is the optimal piece of equipment for making a pot roast since the low and slow cooking method results in a flavorful and tender piece of meat. The pot roast takes just 15 to 20 minutes of preparation before it's time to put all of the ingredients in the slow cooker; then set it and forget about it until dinner time.

The pot roast is first dusted with flour and browned in a skillet, and then placed on top of chopped onions, potatoes, and carrots in the slow cooker, and left to cook for several hours. If you like, you can make a simple gravy using the drippings with some flour once the beef is ready. This one-dish meal is perfect at the end of a busy day and comforting on a cold night.

Slow Cook the Meat and Vegetables

  1. Cut the onions in half lengthwise. Peel and cut them crosswise into 1/4-inch slices. Place the onions in the bottom of a 3 1/2-quart or larger crock pot.

  7. Cover the pot and cook on the LOW setting for 8 to 10 hours, or on the HIGH setting for about 4 1/2 to 5 1/2 hours. The roast should be almost falling apart, and the vegetables should be tender. For a shreddable roast, longer is better.

Tips

  • The best cuts for pot roast are often labeled "pot roast." For the most flavorful and succulent beef, use a lean chuck roast, bottom round, or rump roast. A bone-in 7-bone roast is another excellent option, but it is quite large, so make sure your slow cooker is big enough to accommodate it. Or you could ask the butcher to cut it in half.
  • The caramelization obtained by browning the beef first can greatly enhance the flavor, color, and texture, but it is not absolutely necessary. If you are short on time, simply season the beef and place it directly in the slow cooker without browning. (Eliminate the flour and oil.)
  • Low starch potatoes, such as red-skinned or round white, are the best choice for slow cooker dishes because they hold up well. 

Recipe Variations

  • You can use parsnips, turnip, rutabaga, or other root vegetables in this dish. If you choose a more delicate vegetable, such as frozen peas or green beans, wait until about 30 minutes before the roast is ready to add to the slow cooker.
  • For some Italian flavor, add a 14 1/2-ounce can of diced or crushed tomatoes to the roast along with 2 cloves of minced garlic and 1/2 teaspoon of dried basil.
  • Replace part of the water or beef stock with red wine for a richer flavor. Use a cabernet, merlot, or another good quality dry red wine.
