Beef mashed potatoes and carrots on a white plate

Pot roast is one of my favorite things to make on Sundays or for big family gatherings. It makes the house smell amazing as it cooks away and really is a comfort food! I have made this pot roast dozens of times and it has become kind of famous among-st my friends and family! I love this recipe because it is basically fool-proof, and the meat turns out melt-in-your-mouth tender every time.

The gravy is also full of flavor! If you are nervous about porcini mushrooms or don’t think you like them, don’t worry. They get pureed up into the gravy and give the sauce a wonderful depth of flavor. Nobody can ever guess they are the secret ingredient! I like porcini mushrooms best, but you can use any kind of dried mushrooms you can find. This trick would also work great for this frozen roast in the instant pot.

I often add yukon gold potatoes and chopped carrots to this about 1 1/2 hours before it’s done cooking. I just add them right on top of the meat. Then when the meat is done, you have an entire meal! This is also delicious over mashed potatoes, polenta, or buttered noodles. This pot roast makes a great holiday meal!

Slow-Cooker Pot Roast with Porcini Mushroom Gravy {Gluten-Free}

Prep Time 30 mins
Cook Time 6 hrs
Total Time 6 hrs 30 mins
Servings 8 servings
A rich pot roast that's full of great flavors


  • 1 4- pound boneless chuck roast
  • 1 yellow onion chopped
  • 3 carrots chopped
  • 1 stalk celery chopped
  • 4 cloves garlic smashed and peeled
  • 1 sprig fresh rosemary or 1/2 teaspoon dry rosemary
  • 2 sprigs fresh thyme or 1/2 teaspoon dry thyme
  • 1 cup red wine
  • 1/2 ounce dry porcini mushrooms rinsed very well
  • 2 teaspoons Worcestershire sauce
  • 2 bay leaves
  • 1-2 cups beef stock or broth


  • 2 pounds small yukon gold potaoes left whole
  • 1 pound carrot cut into 2-inch pieces


  • Pat the beef dry with paper towels and season with salt and pepper.
  • Heat 2 tablespoons of olive oil in a large dutch oven or heavy-bottomed pan over medium-high heat. Add the beef and cook until browned on all sides, about 10-15 minutes.
  • Remove the beef from the dutch oven and place it in the slow-cooker. Add the onions, carrots, and celery to the now empty dutch oven and cook until tender, about 6-8 minutes.
  • Add the garlic, rosemary, and thyme and cook for another 30 seconds. Pour in the wine and scrape up all the browned bits from the bottom of the pan (all the flavor!). Allow the wine to cook and reduce for 3-4 minutes.
  • Pour the wine/vegetable mixture over the beef in the slow-cooker. Add the porcicni mushrooms, worcestershire sauce, bay leaves, and 1 cup beef broth.
  • IF USING: Layer potatoes and carrots over onion layer in slow cooker, then season with salt and pepper.
  • Cook on low for 6-8 hours or on high for 3-4 hours until the roast and vegetables are tender.
  • After the roast is done cooking, remove the meat (and potatoes/carrots - the smaller chopped carrots can be blended up with the gravy) from the slow-cooker and place it on a serving platter tented with foil.
  • Remove and discard the rosemary sprigs, thyme sprigs, and bay leaves. Skim as much fat as you can off the surface of the remaining liquid. Pour the liquid, including all the vegetables, into a blender and blend until smooth.
  • Slice or shred the meat and pour over the gravy. Serve, passing the remaining gravy. Enjoy!


*I often add yukon gold potatoes potatoes and carrots chunks to this about 1 1/2 hours (or 1 hour if you're cooking it on high/in the oven) before the roast is supposed to be done cooking. Just add them right on top of everything.
*While I like porcini best, you can use any dried mushrooms you like. Trader Joe's sells a package of a mixed variety of mushrooms that will work.
*To make this in the oven, place everything in a large dutch oven and bake at 350 for about 3 hours. Then proceed with making the gravy.

  1. I made this recipe for my book club last fall and it was a huge hit!! I was kicking myself because I couldn’t find the recipe last night and I really wanted to make it again. Luckily, I went all the way back in to my search history and was able to pull it up. But THAT’S how good it was! Simple, healthy, and delicious. Thank you!

  2. I made this yesterday for friends and it was a huge hit. Dried mushrooms are not available where I live, so I used a can of mushrooms, drained, and added them 2 hours before the end of cooking.
    The gravy is so flavourful, the beef so tender. This has now become my go to recipe for doing roast beef.


  3. This was SO good. Made it along with the Gluten Free Peach & Blueberry Cobbler tonight. Such a fantastic Sunday Dinner. Both were easy recipes to follow and turned out beautiful.

  4. I’ve never reviewed a recipe before but this one was so good that I just wanted to thank you. This recipe was so easy to prepare and my family just loved it. I love the fact that the gravy was naturally thickened just by sticking it in the blender. I didn’t have a 4lb roast as was suggested. I had a 2lb chuck so I just cooked it on low for a little under 8 hours. Once again thanks for a great recipe.

  5. I found this recipe on Foodgawker and it fit the bill — simple, slow-cooker pot roast — and I made it tonight. Outstanding!! Excellent taste and very easy to make. I used a 4lb grass fed chuck roast from a local ranch. I’ll be checking back into your website for more ideas.
