Slow Cooker Roast Beef

When chilly fall weather strikes, one of our family favorites is a pot roast dinner. Garlicky mashed potatoes, carrots, homemade dinner rolls, and a rich beef gravy – YUM! Don't forget to check out all our other fall recipes!


The easiest way to make the perfect beef roast is by using the crockpot. Throw everything in it in the morning, turn it on low, and at dinnertime, you only need a few minutes to have a delicious dinner ready to serve!

Start by seasoning your roast. I like to keep it simple and use garlic powder, onion powder, pepper, and salt, but you could use a beef rub, seasoning salt, or whatever you prefer.

Brown Roast Beef

Heat a skillet (I love cast iron) and add a couple tablespoons of your favorite oil.  My husband is partial to using either olive or peanut oil, but I like to use coconut oil when he's not looking. Sear the meat by browning on each side

Chop or slice an onion and throw it in the crockpot while you wait for the beef to brown.

Lay your roast on the onions. In your skillet, add 1 1/2 cups of red wine and deglaze the pan while simmering for about a minute.  Pour your wine glaze over the roast and onions.

Roast Beef with carrots and potatoes

Place some peeled carrots around the roast, and then peel, wash, and cut up some potatoes. Put them on top of the roast. Cover and cook on low for 6-8 hours. You can cook it on high for 4-5 hours, but I think the meat texture is better when its done slowly.

Take the potatoes out once they are cooked through and mash. I like to use butter, milk, a little cream cheese, roasted garlic (or garlic powder). Put the mashed potatoes into the fridge until the roast is done, fork tender.

Once the roast is done, transfer the juices to a skillet and simmer.  Whisk in a basic roux (I normally do a cornstarch slurry, but you can do butter & flour if you prefer) and cook until it has thickened to your desire. Season with salt & pepper, to taste. Serve the roast with carrots, mashed potatoes,  and your favorite homemade rolls!
