Ingredients and Measurements

• 3–4 pound chuck roast, trimmed of excess fat
• 3 tablespoons olive oil
• 1 yellow onion, sliced into 1/2” rings
• 6 cloves garlic, smashed
• 2 tablespoons tomato paste
• 2 teaspoons brown sugar
• 2 teaspoons Italian seasoning
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon chili powder
• 2 teaspoons Worcestershire sauce
• 32 ounces beef stock
• 2 pounds carrots, peeled and cut into 2-3” pieces
• 2 pounds baby gold potatoes, halved if large
• 4 sprigs fresh thyme
• 4 sprigs fresh rosemary
• 2 bay leaves
• 3 tablespoons cornstarch, optional (for gravy)
• Kosher salt
• Freshly cracked black pepper
• Fresh chopped parsley, for garnish

Step-by-Step Cooking Directions

1. Trim excess fat from the chuck roast and pat the roast dry.
2. Slice the yellow onion into 1/2″ rings and smash the garlic cloves; peel and cut carrots into 2–3″ pieces and halve large baby potatoes.
3. Warm olive oil in a large sauté pan over medium-high heat until shimmering.
4. Season the roast all over with kosher salt and freshly cracked black pepper and sear in the hot pan, browning each side and the edges about 4–5 minutes per side; transfer the roast to the slow cooker.
5. Reduce pan heat to medium, add the sliced onion with a couple pinches of salt and pepper and cook, stirring occasionally, about 4 minutes until soft.
6. Stir in garlic, tomato paste, brown sugar, Italian seasoning, garlic powder, onion powder, and chili powder with additional salt and pepper and cook 1 minute.
7. Pour in Worcestershire sauce and a few splashes of beef stock, scraping up browned bits to deglaze the pan.
8. Pour the onion and garlic mixture over the roast in the slow cooker; add the carrots and potatoes and pour in the remaining beef stock; season with generous pinches of salt and pepper and tuck in thyme, rosemary sprigs, and bay leaves.
9. Cover and cook on high for 5–6 hours or low for 8–10 hours, until the roast is tender enough to shred easily with forks.

10. If the vegetables become fork-tender before the roast is shreddable, remove the vegetables, let the roast finish cooking, then return the vegetables to the slow cooker to warm for 20–30 minutes.

    

11. Strain the cooking liquid into a saucepan, whisk a slurry of 3 tablespoons cornstarch and 3 tablespoons cold water into the liquid, and heat over medium, stirring frequently, until the gravy thickens; season to taste with salt and pepper.
12. Garnish the pot roast with chopped fresh parsley.

Smart Shortcuts and Tips

• Cut carrots evenly so they’re close in size to the potatoes. This helps them cook evenly and be done at the same time. I prefer baby potatoes because they need little prep.
• Use a wide sauté pan or cast iron skillet to sear the roast. This gives you plenty of surface area for a great crust and makes moving the roast to the crock pot easier—see the technique in our easy tender crockpot pot roast dinner recipe.
• Don’t skip searing or sautéing! They bring out big flavors and make the roast super juicy—just like in our Crock Pot Pork Roast and Gravy. It’s worth the few extra minutes.
• Check your slow cooker partway through. If veggies are done but the roast isn’t shredding, take veggies out and finish cooking the meat. Pop veggies back in near the end just to heat through.
• A 6-7 quart slow cooker fits this recipe perfectly. If your cooker is smaller, just cut the roast into two pieces and sear and cook them separately.

Flavor Variations and Swaps

Although chuck roast is the classic choice for a slow cooker pot roast, several other cuts work well too. Here are my favorites in order:

• Chuck roast
• Round roast (bottom round or rump roast)
• Shoulder roast
• Brisket
• Short ribs

Look for meat with good marbling—that nice streak of fat helps keep the roast juicy during the long slow cook. Slow cooking breaks down connective tissue, turning tougher cuts into tender, flavorful beef that falls apart with a fork—just like in our Slow Cooker Beef Stew.

Make-Ahead, Storage, and Reheating

• This slow cooker pot roast is a lifesaver for meal prep! I love making it on a Sunday afternoon and then having easy lunches or dinners ready all week long. If youre building a cook-once, eat-all-week menu, add a batch of Crock Pot Loaded Baked Potato Soupit reheats beautifully.
• The beef stays juicy and tender even after reheating, so leftovers dont feel dry or boring. The gravy also heats up nicely, keeping everything flavorful. For a quick veggie side to serve with reheated pot roast, try Skillet Zucchini and Mushrooms.

• STORING: Keep leftover pot roast and veggies fresh in an airtight container for up to one week. Make sure the beef stays covered in the cooking juices or gravy so it wont dry out.
• FREEZING: Freeze leftovers in an airtight container, submerged in its juices or gravy, for up to three months. Defrost overnight in the refrigerator before reheating.
• REHEATING: Warm leftovers gently on the stove over medium heat. Add the shredded beef, veggies, and some broth or gravy to a saucepan. Stir occasionally until everything is heated through. Taste and adjust salt and pepper before serving.

Common Questions and Answers

• Can I use a different beef cut? Definitely! Chuck roast is ideal for marbling and tenderness, but bottom round, shoulder roast, brisket, or short ribs all work. Just pick cuts with some fat for juicy results.
• Is searing the roast necessary? It’s not mandatory, but I highly recommend it. Searing locks in flavor and improves texture. Without it, your pot roast will still cook but won’t have as deep a flavor.
• Should I cook on high or low? Either works depending on your day—high for about 5–6 hours or low for 8–10 hours until the roast pulls apart easily. Cooking times can vary by slow cooker and size of the roast.
• When do I add the vegetables? Add carrots and potatoes at the start—just as you would in a slow cooker beef stew. If they become too soft before the roast is tender, remove them once fork-tender, let the roast finish cooking, then return veggies to warm through for the last 20-30 minutes.
• How do I adjust the gravy’s thickness? For thicker gravy, use the full cornstarch slurry (3 tbsp cornstarch + 3 tbsp cold water) and let it simmer until thickened. For thinner gravy, use less slurry or add some extra beef stock to thin it out. For a step-by-step example of simmering and thickening gravy, see Salisbury Steak with Mushroom Gravy.
• How do I store and freeze leftovers? Store in airtight containers in the fridge for up to a week, keeping meat submerged in juices or gravy to prevent drying. Freeze for up to three months in airtight containers and thaw overnight in the fridge before reheating.
• What’s the best way to reheat pot roast? Reheat on the stove over medium heat, stirring occasionally with some cooking liquids or gravy to keep the beef moist and flavorful.
• What size slow cooker do you recommend? A 6–7 quart slow cooker fits this recipe best. If your slow cooker is smaller, just cut the roast into smaller pieces and cook accordingly.
