Slow Cooked Roast with Creamy Mushroom Gravy
This smothered Slow-Cooked Roast with Creamy Mushroom Gravy is comfort food at its best. Seasoned to perfection, the chuck roast slow-braises until it’s melt-in-your-mouth tender. I like to toss in fresh baby carrots and sweet pearl onions for added flavor with minimal effort. Let it simmer all day, and by dinnertime, your meal is ready, and your kitchen smells amazing.
Ingredients to Make Slow Cooked Roast with Creamy Mushroom Gravy Recipe
Sunday roast was tradition in my family and one of my sweetest childhood memories. It’s comfort food and one that doesn’t have to be incredibly difficult to make. Using your slow cooker to make inexpensive cuts of meat like chuck roasts, puts the magic in the flavor and gives it the most tender texture. Slow cooking allows you to turn many cheaper cuts of meat into fall apart deliciousness. I make several variations of slow cooked roasts these days but this one tops my list due to its simplicity. Ingredients to make simple Pot Roast with Mushroom Gravy in a Slow Cooker: (Scroll down for the full printable recipe card.)
- Beef – Chuck roast is the perfect cut of beef for slow cooking. It results in a tender fall apart pot roast that’s smothered with mushroom gravy.
- Seasonings – Steak seasoning, salt and black pepper and garlic. Steak seasoning blend i.e. Meat Magic or Chicago Steak or Montreal Steak Seasoning.
- Simple Mushroom Sauce – One can French onion soup, one can cream of mushroom soup and Worcestershire sauce. Loads of flavor with no fuss.
- Additions – One package of frozen pearl onion and baby carrots.
What Happens if You Don’t Sear the Roast Before Cooking?
Searing the roast is an extra step in the process that gives the beef depth of flavor and enhances the taste. It helps to seal the juices, and sears the seasonings onto the beef. If time doesn’t allow, the roast will still be delicious.

If I could give this recipe 10 stars I would. This recipe couldn’t be any easier. I was having book club and I wanted a recipe I didn’t have to think about. Found this one and it was a huge hit. I think the most amazing part about it was the gravy. Honestly. It never crossed my mind to make gravy with cream of mushroom soup. And, if I’m being honest, I thought it was a little wakadoodle. But I followed the recipe and boy am I glad I did. The gravy was amazing. I also have never made mashed potatoes with my pot roast. Always dropped baby potatoes in the slow cooker. I will never do that again. Mashed potatoes are the answer with pot roast. Thank you for this amazing recipe.
I’m so happy to hear it, thanks so much!
Made this and it was great! The gravy is easy and a standout – plus makes a lot with enough for side dishes, which is a plus! Love slow cooker recipes like this which let you start dinner early and you’re not under the gun and stressed out when dinnertime comes.
I’m so happy you enjoyed it! Thanks for your kind comment.
Great roast!!
Melissa, I was wondering if I could add cubed potatoes ro this. Would you recommend? When would I add them?
You can add potatoes to this roast. You can add them about halfway through cooking as long as they aren’t too small.
Melissa,
Made this recipe this week and it was tender and tasty. The 8-10 hour cooking time on low is tricky for me. Can you adapt it for cooking on high? Want to make it for houseguests next week.
Thank you!
Typically you would adjust by half. This applies entirely to how your appliance performs. On high a range of 4-6 hours.
How much beef broth would i use if i use it instead of wine? Please answer asap. thank you! 🙂
There’s no wine in this recipe. You can use French onion soup as called for or replace it with 2 cups of beef stock.
Melissa, thank you for sharing this delicious recipe. My chuck roast was frozen so I ran it under running water to get the frost off then patted it dry and rubbed it with Montreal steak seasoning. Browned it in my cast iron pan, put it in my roaster, finished the instructions and put it in the oven covered at 320* as I don’t have a slow cooker. Turned it down to 180* after 3 hours, added the onions and left it for another hour and a half. So tender and so tasty. My husband said it is the best roast ever. Thank you again…
I love your adaptation to the oven, thank you for sharing!
Hello Melissa does this recipe work on a frozen chuck roast?? or is it suppose to be thawed??
……I will be trying this recipe tomorrow or even tonight, so I’d appeciated a feedback to my comment asap! 🙂
Thankss
You should make this with a thawed chuck roast, yes.
Thank you for this recipe. I know it’s been out for a while, but I just fixed it tonight for Sunday dinner (July 2021). It was sooooo… good! My husband was wiping the plate clean with his cornbread. Perfect recipe! Didn’t need to alter in any way.
Hi Phyllis, I make this roast ALL the time and I’m delighted to know you’re enjoying it! It’s a classic dinner for us, thank you so much for such a sweet note.
I am definitely going to try this recipe, It looks and sounds delicious.
Do you need to pour off some of the oil before adding soup? Also do you really need 1/2 cup oil to brown the roast? Thank you!
This recipe calls for 1/4 cup oil. It’s up to you if you want to adjust that amount.
Hi! Just want to say I’ve been making this roast recipe for a couple years now and it’s always a hit! So delicious!!
Hi Sara, thanks so much for taking the time to let me know, it’s much appreciated!
