Ingredients
- 1 (3–4 lb or 1.3–1.8 kg) beef chuck roast
- 1 packet (1 oz or 28 g) dry Ranch seasoning mix
- 1 packet (0.7 oz or 20 g) dry Italian dressing mix
- 1 packet (0.87 oz or 25 g) dry brown gravy mix (or dry beefy onion soup mix)
- 1 cup (240 ml) low-sodium beef broth or water
- 2 large potatoes (Russet or Yukon Gold), cut into 1 1/2-inch chunks (about 1.5 lbs or 680 g)
- 1 lb (450 g) carrots, peeled and cut into 2-inch chunks
Optional for Flavor & Texture
- 1 tbsp (15 ml) olive oil (for searing)
- 2 tbsp cornstarch + 3 tbsp cold water (for final gravy thickening)
- 1/2 cup chopped yellow onion (add with vegetables)
Equipment
- 6-quart or larger slow cooker (Crock-Pot)
- Whisk
- Small skillet (optional, for searing)
- Small saucepan (optional, for gravy)

Step-by-Step Instructions
- Prep the Slow Cooker: Lightly grease the slow cooker basin or line it with a slow cooker liner for easiest cleanup.
- Prep Vegetables (The Bed): Place the chunky potatoes and carrots (and optional onion) evenly on the bottom of the slow cooker. This prevents the beef from sticking to the bottom and allows the vegetables to soak up the juices.
- Sear the Beef (Optional but Recommended): Pat the chuck roast dry with paper towels. In a small skillet over high heat, heat the olive oil until shimmering. Sear the roast for about 2 minutes per side until a deep brown crust forms. Transfer the seared roast directly onto the bed of vegetables in the slow cooker.
- Mix and Pour Sauce: In a bowl, whisk together the Ranch seasoning mix, Italian dressing mix, brown gravy mix, and the beef broth (or water) until the powders are dissolved.
- Cook Low and Slow: Pour the seasoning mixture evenly over the roast and vegetables. Cover the slow cooker with the lid. Cook on LOW setting for 8 to 10 hours or on HIGH setting for 4 to 5 hours. The beef is done when it is fork-tender and shreds easily.
- Make Gravy (Optional): Once the roast is done, use a ladle to transfer about 2 cups of the cooking liquid into a small saucepan. Bring to a boil over medium-high heat. Whisk the cornstarch and cold water together in a small bowl to form a slurry. Slowly whisk the slurry into the boiling liquid and simmer for 1–2 minutes until the gravy thickens to your liking.
- Serve: Remove the beef to a cutting board and let it rest for 5 minutes. Shred the beef with two forks and return it to the pot, tossing it with the vegetables and gravy. Serve immediately.
Substitutions and Variations
- Gravy Mix Alternative: Substitute the three packets with 1 can of condensed cream of mushroom soup, 1 packet of dry onion soup mix, and 1/2 cup water/broth.
- Vegetables: Add frozen peas or mushrooms during the last hour of cooking, as they cook much faster than the root vegetables.
- Acidity: For a brighter flavor, replace 1/4 cup of the beef broth with dry red wine or apple cider vinegar when mixing the sauce.
- Oven Method: To cook in the oven, preheat to 325°F (160°C). Place the assembled roast and liquid in a heavy Dutch oven, cover tightly, and bake for 3.5–4.5 hours, or until fork-tender.
Pro Tips and Common Mistakes to Avoid
- Low and Slow is Best: While the high setting is fast, cooking on the LOW setting allows the collagen in the tough chuck roast to break down gradually, resulting in the most tender, moist, and flavorful meat.
- Do Not Open the Lid: Every time you lift the slow cooker lid, you lose about 30 minutes of cooking time. Resist the urge to check on it until the final hours.
- Use Chuck Roast: Chuck roast (or shoulder roast) is the best cut for pot roast because its high fat and connective tissue content melts over time, keeping the meat moist and giving the gravy a rich texture.
- Add the Slurry Slowly: If you opt to thicken the gravy with the cornstarch slurry, add it slowly and whisk constantly. This prevents lumps and allows you to stop thickening when the gravy is just right.
Storage, Make-Ahead, and Reheating
- Make-Ahead (Uncooked): You can assemble the entire hot roast (meat, vegetables, and sauce) in the slow cooker insert, cover it, and store it in the refrigerator for up to 24 hours. When ready, place the insert in the slow cooker base and cook as directed.
- Storage (Leftovers): Store leftover roast, vegetables, and gravy together in an airtight container in the refrigerator for up to 4 days.
- Freezing: This dish is excellent for freezing. Freeze the shredded meat and gravy together in a freezer-safe container for up to 3 months. The root vegetables may become slightly soft upon thawing.
- Reheating: Reheat gently on the stovetop or in the oven at 350°F (175°C) until warm. If reheating in the microwave, add a spoonful of gravy to the meat first to keep it moist.
Serving Suggestions
Serve the shredded beef and tender vegetables over a bed of creamy mashed potatoes, egg noodles, or white rice to soak up all the rich gravy. A side of crusty sourdough bread or simple steamed green beans completes the ultimate comfort meal.

FAQs
Q: Why do I need to sear the meat first?
A: Searing the meat is optional but highly recommended. It creates a dark, flavorful crust (the Maillard reaction) that adds a tremendous amount of depth and savory flavor to the final gravy.
Q: Can I use different vegetables?
A: Yes! You can substitute the carrots and potatoes with turnips, parsnips, celery, or mushrooms. Just be sure to add any quick-cooking vegetables (like peas or mushrooms) only during the last hour of cooking so they don’t overcook.
Q: How do I know when the roast is done?
A: The roast is done when it is fork-tender. The internal temperature will be far past the safe temperature (145°F), usually reaching around 200°F (93°C), which is the point where the tough connective tissue has completely broken down into tender gelatin.
Q: Can I skip the liquid entirely?
A: Most slow cooker recipes recommend at least 1/2 cup to 1 cup of liquid to prevent the seasoning mix from scorching on the bottom of the pot. The meat will release a lot of its own liquid, but the initial broth ensures the seasoning mixes properly and doesn’t burn.
Q: What cut of beef is best for pot roast?
A: Chuck roast (or shoulder roast) is the best choice. It is marbled with fat and connective tissue (collagen) which melts over the long, slow cooking time, keeping the meat moist and resulting in that prized fork-tender texture.
