Slow Cooker Beef Stew with Irish Stout
There’s nothing like a pot of beef stew on a cool fall day. This one starts with a quick balsamic marinade, then the beef gets seared in a seasoned cornstarch dredge before it goes into the slow cooker with stout, sun-dried tomatoes, and a little ranch seasoning. Mushrooms go in near the end, and the result is a rich, glossy gravy and beef that falls apart. Serve it with crusty bread and you’re set.
Prep time: 45 minutes (including marinating) | Cook time: 6-8 hours on low or 4-6 hours on high | Serves: up to 6

Ingredients
Beef and marinade
- 2 lbs beef roast (blade or stewing beef, something that holds up to long cooking), cut into 1-2″ pieces
- Salt, pepper, and Montreal steak spice
- Balsamic salad dressing, enough to coat (marinate at least 20 minutes)
Slow cooker base
- Olive oil, to coat the bottom
- A knob of butter
- 1 to 1½ lbs potatoes, cut into 1-2″ chunks (about 3-4 medium)
- ½ to 1 lb carrots, cut into 1-2″ chunks (about 3-4 medium)
- Garlic, diced
- 4-5 sun-dried tomatoes, diced, plus a little of their oil to taste
- 1 tbsp tomato paste
- ½ to 1 packet dried ranch seasoning
- 1/4 – 1/2 each of Dried thyme and rosemary (to your taste)
- Season with salt and pepper
- 1 cup Irish stout
Dredge and finish
- ¼ cup cornstarch
- 1 tbsp flour (leave out for GF option)
- 1/4 each Salt and pepper
- Olive oil and butter for searing
- 1 medium onion, diced
- ½ cup Irish stout
- Beef stock, enough to bring the liquid up to (but not over) the ingredients
- 1 package sliced mushrooms
Instructions
- Marinate the beef. Cut the roast into 1-2″ chunks. Season with salt, pepper, and Montreal steak spice, then toss with balsamic dressing and let sit for at least 20 minutes. Set aside.
- Prep the slow cooker. Turn it on high to preheat. Drizzle olive oil over the bottom and add a knob of butter. Add the potatoes, carrots, and garlic.
- Add the flavour. Stir in the sun-dried tomatoes and a little of their oil, the tomato paste, ranch seasoning, thyme, rosemary, salt, and pepper. Pour in 1 cup of stout and stir to combine. Cover and set aside.
- Dredge and sear. Heat a frying pan over medium (about 4-6 on the dial). Mix the cornstarch, flour, salt, and pepper, and toss the beef in it. Keep any leftover dredge. Sear the beef in olive oil and butter for 3-4 minutes per side, until golden brown, adding each batch to the slow cooker as it’s done. Don’t crowd the pan.
- Deglaze. In the same pan on medium/low heat, cook the diced onion scraping up the browned bits, 2-5 minutes. Stir in the leftover dredge, then add ½ cup of stout, then add the mixture to the slow cooker.
- Add the stock. Pour in enough beef stock to bring the liquid up to, but not over, the ingredients. You can always add more later.
- Cook. Cook on low for 6-8 hours or on high for 4-6 hours, until the beef is tender and falls apart. I like to start on high for the first 1-2 hours, until bubbles break the surface, then turn it to low for the rest.
- Add the mushrooms. About an hour before the stew is done, stir in the sliced mushrooms. Taste and adjust the seasoning before serving.
Tips
- Chuck or blade roast is best here. The connective tissue breaks down over the long cook and makes the beef tender.
- Searing the beef in the dredge is what gives you a thick, glossy gravy without a separate thickener.
- Need a thicker gravy? Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth, then stir it into the stew. Cook on high for 15-20 minutes with the lid off or slightly ajar until it thickens
- Use more or fewer vegetables depending on how meaty you like your stew.
- Serve with crusty bread or buttered biscuits to soak up the gravy.
