Ingredients
For the Pot Roast:
-
3–4 lb chuck roast
-
2 tablespoons olive oil
-
Salt and black pepper, to taste
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
1 teaspoon paprika
-
1 tablespoon Worcestershire sauce
-
1 large onion, sliced
-
4 carrots, peeled and cut into chunks
-
3–4 potatoes, cut into large pieces
-
4 cloves garlic, minced
-
2 cups beef broth
-
2 tablespoons tomato paste
-
2 sprigs fresh rosemary
-
2 sprigs fresh thyme
-
2 bay leaves
For the Mashed Potatoes:
-
2½ lbs russet or Yukon gold potatoes
-
½ cup whole milk (warm)
-
4 tablespoons butter
-
Salt and black pepper to taste
-
Optional: garlic or sour cream for extra flavor
Step 1: Season and Sear the Roast
Pat the chuck roast dry with paper towels. Season generously on all sides with salt, pepper, garlic powder, onion powder, and paprika. Heat olive oil in a large skillet or Dutch oven over medium-high heat.
Sear the roast for about 3–4 minutes per side, until deeply browned. This step locks in flavor and adds rich depth to the final dish. Once browned, transfer the roast to a slow cooker.
Step 2: Prepare the Vegetables
Add sliced onions, carrots, and potatoes around the roast in the slow cooker. Scatter the minced garlic on top. These vegetables will absorb the flavorful juices as the roast cooks, becoming tender and delicious.
Step 3: Build the Flavor
In a bowl, whisk together beef broth, Worcestershire sauce, and tomato paste. Pour this mixture over the roast and vegetables. Add rosemary, thyme, and bay leaves. The liquid should come about halfway up the meat—this allows slow braising without boiling.
Step 4: Slow Cook to Perfection
Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the beef is fork-tender and easily pulls apart. Slow cooking transforms the tougher cut of beef into something incredibly soft and juicy.
Once done, remove the roast and vegetables from the slow cooker. Discard the herb stems and bay leaves.
Step 5: Make the Mashed Potatoes
While the roast finishes cooking, bring a large pot of salted water to a boil. Add the potatoes and cook until fork-tender, about 15–20 minutes. Drain well.
Mash the potatoes with butter, warm milk, salt, and pepper until smooth and creamy. Adjust seasoning to taste. For extra richness, stir in a spoonful of sour cream or roasted garlic.
Step 6: Optional Gravy
For a thicker gravy, transfer the remaining cooking liquid to a saucepan. Bring to a simmer and whisk in a slurry made from 1 tablespoon cornstarch and 2 tablespoons water. Cook until thickened, then pour over the roast and potatoes.
Step 7: Serve and Enjoy
Serve the pot roast sliced or shredded, spooning the rich gravy over the top. Add a generous scoop of mashed potatoes and a portion of tender carrots and onions on the side.
