This slow cooker pot roast is LOADED with garlic and onion flavor.

Do you love cooking with onions and garlic? I do too. Whoever I am talking to after eating them may not love them as much as I do. That’s why it’s important to always get your friends and family to eat as much stinky food as you do so you can’t smell each other. That’s my lesson for the day.
This pot roast is heavy on the onion and garlic. Whole cloves of garlic are stuffed into the meat, and then it’s smothered with onions and cooked all day. It’s kind of like french onion soup, except with a lot more beef.

You may remember that I said we were eating less beef, and that’s totally true. This particular roast was in the clearance section for 50% off though, and I’m not going to pass up that kind of deal. Under $10 for a big, beautiful beef roast? Don’t mind if I do!

I served this roast over rice with its juices straight out of the crockpot, but you could make a thicker gravy if you prefer. To do this, make a roux with a tablespoon of butter and a tablespoon of flour. Then, slowly whisk in 1-1/2 to 2 cups of cooking juices and simmer until thickened. Season with salt and pepper to taste, but the juices are already pretty flavorful. This is just a quick description of the process, but you can see a full video of how to make gravy here.

What side dish will you serve with your roast? We had simple green beans with butter, salt, and pepper. If you wanted to get fancy, you could serve up healthy creamed spinach or green bean casserole.

I am seriously obsessed with garlic, and I always tend to over-garlic like everything I make…if there is such a thing as “over-garlicking.” I would totally be in love with this pot roast. Looks so comforting!
Andi Gleeson says
You would like this one for sure then, Justine. Thank you!!
Shaye says
Would this work in my 4 qt crockpot?
Andi Gleeson says
Hi, Shaye! It should work fine. I would just keep your size crockpot in mind when choosing your cut of meat to pick something that will fit. I hope you like it!
