How often do you use your slow cooker?  I have been relying on mine at least once a week.  I thought you might enjoy a few of these easy recipes, like this Crock Pot Roast with Caramelized Onions to get dinner on the table with very little effort.

How To Make Pot Roast with Caramelized Onions

  • I do recommend brown the pot roast before you stick it in the crock pot.  It does take about 15 minutes but the results are totally worth while.
  • Cook onions and garlic until caramelized and and place over the browned pot roast.
  • Add in the liquid mixture and let your slow cooker work it’s magic!
  • You will get a rich and delicious gravy that will be wonderful over mashed potatoes!Beef pot roast in slow cooker topped with caramelized onions

When it comes to comfort food, pot roast is hard to beat and if you have leftovers it makes amazing sandwiches especially with homemade Horseradish Sauce!

My Beer Braised Pot Roast is also a Sunday favorite and is totally adaptable for the slow cooker as well. If you are into grilling, we love this Grilled Chuck Roast that makes the most incredible sandwiches.

I absolutely loved the savory gravy that this roast made.  I used a mix of vegetable juice and coffee for the cooking liquid and I know that sounds a little crazy but it totally worked.

You get all of that great vegetable flavor minus the mushy vegetables.  It’s not my mother-in-law’s gravy (which is the over the top amazing) but it was great.  To get that great gravy you HAVE to brown the roast, don’t skip it!

  1. I love pot roast. I feel kind of boring because I have the urge to cook it all the time. I don’t, but I want to.
    But this is still yummy traditional with a change up zing to it. Yes, I have an excuse to fix pot roast!!!!

    1. Hi Karen, If you cook it to 170 degrees it will be cooked through and sliceable. If you cook it for about another hour it should become a little more tender. I hope this is helpful.

    Hey, I am planning to prepare this next week for my husband birthday. But I am wondering if I can use roasted peking duck as my meat, peking duck from Mott 32 (http://mott32.com/) is his favorite and I just want to give it a new taste. Maybe caramelizing it with onions will make it uniquely the best.

  3. Wow! Just make sure you look at the full post for directions for Roast and Onionsprep! The printed recipe only has directions for the Gravy! Haha.
