Ingredients
For the Pot Roast
3 to 4 pounds beef chuck roast
2 tablespoons olive oil
1 teaspoon salt
1 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 large onion, sliced
4 cloves garlic, minced
4 large carrots, cut into chunks
3 celery stalks, chopped
3 cups beef broth
1 tablespoon Worcestershire sauce
2 tablespoons tomato paste
2 teaspoons fresh thyme (or 1 teaspoon dried thyme)
2 bay leaves
For the Gravy
2 tablespoons butter
2 tablespoons all-purpose flour
1 to 2 cups cooking liquid from the pot roast
Salt and pepper to taste
For the Creamy Mashed Potatoes
2 pounds Yukon Gold or Russet potatoes
4 tablespoons butter
½ cup warm milk or heavy cream
½ teaspoon salt
¼ teaspoon black pepper
Optional: 2 tablespoons sour cream or cream cheese for extra creaminess
Step-by-Step Cooking Instructions
Step 1: Prepare the Beef
Start by patting the chuck roast dry with paper towels. This step helps create a better sear.
Season the roast evenly on all sides with salt, black pepper, garlic powder, and onion powder.
Step 2: Sear the Roast
Heat olive oil in a large Dutch oven or heavy pot over medium-high heat.
Place the roast in the hot oil and sear it for about 4 to 5 minutes per side until a deep brown crust forms. This process locks in flavor and enhances the richness of the dish.
Once seared, remove the roast and set it aside on a plate.
Step 3: Cook the Aromatics
In the same pot, add sliced onions and cook for about 3 minutes until softened.
Add the minced garlic and cook for another 30 seconds until fragrant.
Stir in the tomato paste and cook for one minute to deepen its flavor.
Step 4: Add the Vegetables and Liquid
Add carrots and celery to the pot.
Pour in the beef broth and Worcestershire sauce, scraping the bottom of the pot to release any browned bits. These bits add intense flavor to the gravy.
Add thyme and bay leaves.
Return the seared roast to the pot, ensuring it is partially submerged in the liquid.
Step 5: Slow Cook the Pot Roast
Cover the pot with a lid and cook using one of the following methods:
Oven Method
Cook in a preheated oven at 300°F (150°C) for about 3 to 3½ hours.
Slow Cooker Method
Transfer everything to a slow cooker and cook on low for 8 hours or high for 5 to 6 hours.
The roast is ready when it easily pulls apart with a fork.
Preparing the Creamy Mashed Potatoes
Step 1: Boil the Potatoes
Peel the potatoes and cut them into evenly sized chunks.
Place them in a large pot and cover with cold water. Add a pinch of salt.
Bring to a boil and cook for 15 to 20 minutes until the potatoes are fork-tender.
Step 2: Mash the Potatoes
Drain the potatoes and return them to the pot.
Add butter and begin mashing with a potato masher.
Slowly pour in warm milk or cream while mashing until the potatoes become smooth and creamy.
Add salt, pepper, and optional sour cream or cream cheese for extra richness.
Making the Homemade Gravy
Once the roast is finished cooking, remove the meat and vegetables from the pot.
Strain the cooking liquid and reserve about 2 cups.
In a saucepan, melt butter over medium heat.
Whisk in the flour and cook for 1 to 2 minutes to form a roux.
Gradually whisk in the reserved cooking liquid while stirring constantly.
Simmer for 3 to 5 minutes until the gravy thickens.
Season with salt and pepper to taste.
Assembling the Dish
Place a generous serving of creamy mashed potatoes on a plate.
Top with tender shredded pot roast and cooked vegetables.
Spoon warm homemade gravy over the meat and potatoes.
Serve immediately while hot.
Cooking Tips for the Best Pot Roast
Choose the Right Cut
Chuck roast works best because it contains enough fat and connective tissue to become tender during slow cooking.
Do Not Skip Searing
Searing adds deep flavor and helps build the base of the gravy.
Cook Low and Slow
The longer cooking time allows collagen in the meat to break down, making the roast tender and juicy.
Use Warm Milk for Potatoes
Cold milk can make mashed potatoes gluey.
Serving Suggestions
This hearty dish pairs well with:
Buttered green beans
Roasted Brussels sprouts
Dinner rolls
Simple garden salad
Storage and Reheating
Refrigerator
Store leftovers in an airtight container for up to 4 days.
Freezer
Pot roast and gravy can be frozen for up to 3 months.
Reheating
Warm slowly on the stovetop or microwave with a splash of broth to maintain moisture.
