Slow Cooker Pot Roast with Potatoes and Carrots
There are some dinners that just feel like home, and slow cooker pot roast is definitely one of them. I usually make this when I want something hearty and comforting without spending the whole afternoon in the kitchen.
The beauty of this recipe is how simple it is. A well-seasoned beef roast goes into the slow cooker with potatoes, carrots, onions, garlic, and a savory cooking liquid. Then you basically let the slow cooker do all the work. Honestly, the hardest part is waiting for that amazing smell to fill the kitchen!
After several hours of slow cooking, the beef becomes incredibly tender, while the potatoes and carrots soak up all those delicious juices. The result is a classic Crock Pot pot roast that’s perfect for a Sunday dinner, a cozy weeknight meal, or feeding a hungry family.
Ingredients
For the Pot Roast
- 3–4 pounds beef chuck roast
- 1½ pounds baby potatoes or Yukon Gold potatoes, cut into large chunks
- 4–5 large carrots, peeled and cut into 2-inch pieces
- 1 medium yellow onion, sliced or cut into chunks
- 4 cloves garlic, minced
- 2 cups beef broth
- 2 tablespoons Worcestershire sauce
- 2 tablespoons olive oil
- 1 tablespoon tomato paste
- 1½ teaspoons kosher salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- ½ teaspoon paprika
Optional for the Gravy
- 2 tablespoons cornstarch
- 3 tablespoons cold water
How to Make Slow Cooker Pot Roast
1. Season the Beef
Pat the chuck roast dry with paper towels. This helps the seasoning stick and gives you a better sear.
Season all sides generously with salt, black pepper, garlic powder, onion powder, paprika, thyme, and rosemary.
I usually don’t skimp on the seasoning here because the roast is a big piece of meat, and you want the flavor to reach throughout the dish.
2. Sear the Roast
Heat the olive oil in a large skillet over medium-high heat.
Add the seasoned roast and sear it for about 3–4 minutes per side, until deeply browned.
This step isn’t absolutely required, but I highly recommend it. That browned crust adds so much flavor to the finished pot roast.
Transfer the roast to your slow cooker.
3. Prepare the Vegetables
Add the potatoes, carrots, onion, and garlic around the roast.
Try to keep the vegetables in fairly large pieces. Smaller pieces can become overly soft during the long cooking time.
4. Make the Cooking Liquid
In a bowl, combine the beef broth, Worcestershire sauce, and tomato paste.
Pour the mixture into the slow cooker around the roast.
You don’t need to completely submerge the beef. The slow cooker will trap steam and moisture as everything cooks.
5. Slow Cook
Cover the slow cooker and cook on:
- LOW for 8–9 hours, or
- HIGH for 4–5 hours
The roast is ready when it is fork-tender and pulls apart easily.
I personally prefer cooking it on LOW. It takes longer, but the beef becomes wonderfully tender and the vegetables have plenty of time to absorb the savory cooking juices.
6. Make the Gravy
Once the roast is finished, carefully transfer the beef and vegetables to a serving platter.
For a thicker gravy, pour some of the cooking liquid into a saucepan.
Mix the cornstarch with cold water to make a smooth slurry. Whisk it into the hot cooking liquid and simmer for a few minutes until thickened.
Taste and adjust the seasoning if necessary.
7. Rest and Serve
Let the roast rest for about 10–15 minutes before slicing or shredding.
Spoon plenty of the rich gravy over the beef and vegetables, then serve while everything is hot.
Cooking Tips for the Best Crockpot Pot Roast
Choose chuck roast
Beef chuck roast is my favorite cut for this recipe because it has enough marbling and connective tissue to become tender during long, slow cooking.
Don’t cut the vegetables too small
Large chunks of potatoes and carrots hold together much better during several hours of cooking.
Sear the beef first
Again, you can technically skip this, but I wouldn’t if you have the extra 10 minutes. A good sear gives the roast a much deeper, richer flavor.
Don’t lift the lid constantly
I know it’s tempting! But every time you open the slow cooker, heat escapes. I usually leave it alone until the cooking time is nearly finished.
Don’t overcook the vegetables
If you prefer firmer vegetables, you can add the carrots and potatoes partway through cooking rather than putting them in right at the beginning.
Let the roast rest
Giving the beef 10–15 minutes to rest makes it easier to slice and helps keep it juicy.
What to Serve with Pot Roast
This meal is already packed with beef, potatoes, and carrots, so you really don’t need much on the side.
If I’m serving it for a larger family dinner, I like adding:
- Warm dinner rolls
- Crusty French bread
- Green beans
- A simple green salad
- Steamed broccoli
- Buttered peas
- Creamy mashed potatoes
And honestly, don’t forget the gravy. That’s one of the best parts!
How to Store Leftover Pot Roast
Allow the leftovers to cool, then place the beef and vegetables in an airtight container.
Store in the refrigerator for up to 3–4 days.
You can reheat individual portions in the microwave, or gently warm everything in a covered skillet or saucepan with a little beef broth.
The leftovers are also fantastic shredded and tucked into sandwiches.
Can You Freeze Pot Roast?
Yes! Pot roast freezes very well.
Place cooled beef and vegetables in freezer-safe containers or bags and freeze for up to 3 months for best quality.
Thaw overnight in the refrigerator and reheat gently. The potatoes may soften a little after freezing, but the beef should still be delicious.

Frequently Asked Questions
1. What is the best cut of beef for slow cooker pot roast?
Chuck roast is generally the best choice. It has enough fat and connective tissue to become tender and flavorful during slow cooking. Brisket or bottom round can also work, although the texture will be different.
2. Should I sear the roast before putting it in the slow cooker?
You don’t have to, but I strongly recommend it. Searing creates a browned exterior and adds another layer of savory flavor to the finished pot roast.
3. Can I cook pot roast on HIGH instead of LOW?
Absolutely. Cook it on HIGH for approximately 4–5 hours instead of 8–9 hours on LOW. For the most tender texture, though, I usually choose the LOW setting.
4. Why is my pot roast tough?
If the roast is tough but otherwise cooked, it may simply need more time. Chuck roast contains connective tissue that needs enough time to break down. Continue cooking until the beef is genuinely fork-tender.
5. Can I make this pot roast without potatoes?
Yes. You can leave the potatoes out and add extra carrots, mushrooms, onions, or other sturdy vegetables. You can also serve the finished roast with mashed potatoes, rice, or crusty bread.
Final Thoughts
This slow cooker pot roast with potatoes and carrots is exactly the kind of recipe I come back to when I want something comforting without a lot of fuss. The beef turns wonderfully tender, the vegetables become flavorful and buttery, and the cooking juices make an incredible gravy.
Honestly, once everything is in the slow cooker, you can walk away and let dinner take care of itself. And when you finally lift the lid after hours of slow cooking, that rich aroma makes all the waiting worth it.
