This turned out to be the best pot roast I’ve ever cooked, and a few small changes made all the difference. It had been a while since I’d made one, so I asked my sous chef (Claude) to help me tweak my plan, and the final result was amazing.
The night before, I trimmed some excess fat off a high-quality roast and seasoned it well with Terry Black’s Barbecue Beef Dry Rub. Then it went in the fridge overnight on a wire rack.
The day started with sautéed onions and a couple of heaping tablespoons of minced garlic. Then came the seared roast, and the whole house smelled amazing before I even left for school.
I seared it in cast iron on both sides until it had a deep brown crust. That step is worth the extra 15 minutes.
Three changes made this one special:
- The soup and broth slurry. I whisked cream of mushroom soup into beef broth first, then poured most of it around the vegetables in the crock, so the crust stayed above the liquid.
- Glazing the cast iron. After searing, I poured some of that slurry into the hot skillet, scraped up the browned bits, and added them to the crock.
- Potatoes on the side. I microwaved cubed baking potatoes separately and served them alongside, so they didn’t turn to mush and everyone could take as many as they wanted.
After about 8 hours on low, the roast was fork-tender and the gravy was rich and silky.
The cream of mushroom soup and beef broth combined wonderfully for a yummy gravy, that wasn’t thin and didn’t need any corn starch or other additives to make it perfect on baked potatoes. This would also be delicious to serve over brown rice or pasta.

Slow Cooker Beef Pot Roast with Mushroom Gravy
Equipment
- 1 Cast iron skillet
- 1 large crock pot
Ingredients
- 1 high-quality beef roast 4-5 pounds, excess fat trimmed
- Seasoning of your choice for the dry brine Terry Blacks Beef Rub
- Olive oil for searing
- 2 onions chopped into large pieces
- 2 heaping tablespoons minced garlic
- Carrots chopped
- Celery chopped
- 1 1/2 cups beef broth
- 1 can condensed cream of mushroom soup
- Large baking potatoes for serving
Instructions
- The night before: Trim some of the excess fat from the roast, pat it dry, and season it well. Refrigerate it uncovered overnight to dry brine.
- Sauté the aromatics: Cook the onions in a pan until softened, adding the garlic near the end. Spread them across the bottom of the slow cooker, then add the carrots and celery.
- Make the liquid: Whisk the beef broth and cream of mushroom soup together until smooth.
- Sear the roast: Brown the roast on all sides in a hot cast-iron skillet with olive oil. Set it on top of the vegetables.
- Deglaze: Pour a splash of the broth mixture into the skillet and scrape up the browned bits. Add that to the slow cooker.
- Add the liquid: Pour the broth mixture around the roast so it comes about a third to halfway up the meat. Keep the seared top above the liquid.
- Cook: Cover and cook on low for 8 to 10 hours, until a fork twists easily in the meat. Don’t lift the lid while it cooks.
- Finish: Skim any excess fat from the top and taste the gravy before adding any salt, since the soup and broth are already salty.
Potatoes (cooked separately)
Cube the baking potatoes, microwave them covered with a splash of water for 5 to 6 minutes until barely tender, then serve them alongside the roast. Everyone can add as many as they like and spoon the gravy over the top. For a one-pot version, stir the microwaved potatoes into the crock for the last hour on high.
Notes
- Dry brine overnight. I trimmed some of the excess fat off the roast, seasoned it generously with Terry Black’s Barbecue Beef Dry Rub, and left it uncovered on a wire rack in the fridge overnight.
- Sear hard. A deep brown crust on every side builds most of the flavor. Don’t skip it.
- Mix the slurry first. Whisk the beef broth and cream of mushroom soup together before pouring most of it around the vegetables. Set the roast on top so the seared crust stays above the liquid.
- Glaze the cast iron. After searing, pour a splash of the soup and broth mixture into the hot skillet, scrape up the browned bits, and add it to the crock.
- Don’t drown the roast. The liquid should come about a third to halfway up the meat. The crockpot adds moisture as it cooks.
- Cook potatoes separately. Cubed baking potatoes microwaved until just tender and served alongside kept their texture, and everyone could take as many as they wanted.
- Salt last. The rub, broth, and soup are already salty, so taste the gravy before adding any.
