Method
- Brown the beef: Coat the beef chuck pieces in flour. Heat a drizzle of oil in a large skillet over medium-high heat and brown the beef in small batches on all sides, transferring each browned batch to the slow cooker.
- Layer the vegetables: Place the carrots and mushrooms on top of the browned beef in the slow cooker. Season with salt and pepper.
- Build the sauce: In the same skillet, add the diced onion and scrape up the browned bits from the bottom. Pour in the beef broth and red wine if using, then stir in the balsamic vinegar, Dijon mustard, and minced garlic. Pour the sauce over the contents of the slow cooker and top with the fresh rosemary sprigs.
- Slow cook: Cover and cook on LOW for 7-8 hours or HIGH for 3-4 hours, until the beef shreds easily with two forks.
- Thicken the sauce: Near the end of cooking, whisk the arrowroot powder or cornstarch with the water (or a cup of hot stock from the cooker) until smooth, then stir the slurry into the stew and let it thicken.
- Finish and serve: Stir in the frozen peas during the last 10 minutes if using. Serve hot, on its own or over mashed potatoes or cauliflower.
Notes
Beef chuck roast amount is a range (2-3 lbs) per the source article; ingredient list uses this range as text rather than an averaged number. Cook time reflects the LOW slow-cooker setting (7-8 hours, minimum entered); you can instead cook on HIGH for 3-4 hours if you're short on time, though LOW gives the most tender result. Calories are estimated at 380 kcal per serving for the regular version. Nutrition varies based on ingredients and portion size. If you skip the potatoes and use a paleo-friendly thickener like arrowroot. This recipe also works in a Dutch oven (brown beef, build sauce, then cover and bake at 300°F for about 3 hours) or on the stovetop (simmer gently for 2-3 hours in a heavy pot) or in an Instant Pot (sauté, then pressure cook about 40 minutes). Avoid lifting the lid while slow cooking — each peek adds 15-20 minutes to the total time. Leftovers keep in an airtight container in the fridge for 3-4 days, or in the freezer for up to 2 months.
