Ingredients for Garlic Butter Slow Cooker Pot Roast with Potatoes & Carrots
1½ pounds Yukon Gold potatoes, cut into large, approximately 2-inch chunks
1 pound carrots, peeled and cut into thick pieces
6 garlic cloves, minced
1 tablespoon tomato paste
1½ cups low-sodium beef broth
1 tablespoon Worcestershire sauce
1 teaspoon dried thyme
1 teaspoon dried rosemary
2 bay leaves
4 tablespoons unsalted butter, divided
2 tablespoons chopped fresh parsley
For the optional gravy:
2 tablespoons cornstarch
2 tablespoons cold water
About 2 cups cooking liquid from the slow cooker
Instructions for Garlic Butter Slow Cooker Pot Roast with Potatoes & Carrots
1. Season the beef
Pat the chuck roast thoroughly dry with paper towels. Combine the salt, pepper, and paprika, then rub the mixture over every side of the meat.
Drying the surface helps the beef develop a brown crust when it hits the skillet.
2. Sear until deeply browned
Heat the olive oil in a large skillet over medium-high heat. Add the roast and sear for 4–5 minutes on each broad side. Brown the edges briefly with tongs.
Transfer the beef to a plate. Searing builds the savory flavor and browned appearance shown in your reference photo; the slow cooker itself will not create that crust.
3. Prepare the vegetables
Place the onion, potatoes, and carrots in the bottom of the slow cooker. Keep the vegetable pieces fairly large so they hold their shape during the long cooking time.
Set the browned roast over the vegetables.
4. Make the cooking liquid
Reduce the skillet heat to medium. If the skillet is dry, add a splash of broth. Stir in the garlic and cook for about 30 seconds, then add the tomato paste and stir for another minute.
Pour in the remaining beef broth and scrape up the browned bits with a wooden spoon. Add the Worcestershire sauce, thyme, and rosemary.
Bring to a brief simmer, then pour the mixture around the roast. Add the bay leaves and place 3 tablespoons of butter over the beef.
The liquid should pool around the vegetables and lower portion of the roast. It does not need to cover the meat.
5. Cook slowly until tender
Cover and cook on LOW for 8–10 hours or HIGH for 5–6 hours. LOW is preferable for a tender chuck roast.
Begin checking near the earlier end of the cooking range. The beef is ready when a fork enters easily and the meat separates with gentle pressure. The potatoes and carrots should also be tender.
If the roast remains firm, replace the lid and continue cooking, checking every 30–45 minutes. Cooking times vary with the thickness of the meat and the slow cooker.
6. Rest the roast
Carefully transfer the beef to a serving platter. Lift out the vegetables with a slotted spoon and arrange them around it.
Discard the bay leaves. Loosely cover the platter and let the beef rest for 10–15 minutes while you prepare the gravy.
7. Make the gravy
Skim excess fat from the cooking liquid. Measure approximately 2 cups into a small saucepan and bring to a simmer.
Mix the cornstarch with the cold water until smooth. Slowly whisk the slurry into the simmering liquid. Cook for 2–4 minutes, stirring, until lightly thickened.
Add a little more broth if the gravy becomes too thick. Taste before adding extra salt.
8. Finish and serve
Place the remaining tablespoon of butter over the warm roast and sprinkle with parsley. Slice against the grain or pull into generous pieces, depending on how tender it is.
Serve with the potatoes, carrots, and warm gravy.
Tips for the Best Pot Roast for Garlic Butter Slow Cooker Pot Roast with Potatoes & Carrots
Choose chuck roast. Its marbling and connective tissue suit long, moist cooking.
Keep the lid closed. Frequent opening releases heat and can extend cooking time.
Use large vegetable pieces. Small potato cubes and thin carrot slices can become overly soft.
Check tenderness before serving. A roast can be cooked through while still needing more time to soften.
Avoid excess broth. The beef and vegetables release moisture as they cook.
Adjust salt at the end. Broth and Worcestershire sauce contribute their own seasoning.
Variations for Garlic Butter Slow Cooker Pot Roast with Potatoes & Carrots
For a mushroom version, add 8 ounces of halved cremini mushrooms during the final 2–3 hours on LOW.
For a stronger garlic flavor, add a few peeled whole garlic cloves alongside the vegetables. They soften during cooking and can be mashed into the gravy.
For firmer vegetables, add the potatoes and carrots partway through cooking, allowing approximately 4–5 hours on LOW. Work quickly when opening the lid.

This recipe is a complete meal with beef, potatoes, and vegetables. Serve with crusty bread to soak up the gravy, or add steamed green beans or a simple green salad.
Leftover beef also works well in sandwiches. Shred it, warm it gently in a little gravy, and spoon it into soft rolls.
Storage and Reheating
Refrigerate leftovers in shallow, airtight containers within 2 hours of cooking. Store the beef with some cooking liquid to help retain moisture and use within 3–4 days.
Freeze cooled beef and gravy for up to 3 months for best quality. Potatoes may become softer after thawing.
Reheat individual portions in the microwave, covered, or warm gently in a saucepan with a splash of broth until steaming hot throughout.
Frequently Asked Questions for Garlic Butter Slow Cooker Pot Roast with Potatoes & Carrots
Can I skip searing the beef?
Yes. The roast will still cook, but searing gives the finished dish a deeper flavor and more appealing color.
Why is my pot roast tough?
Chuck roast usually needs more time when it remains firm and resistant to a fork. Continue cooking with the lid on. A very lean cut can also produce a drier result.
Can I use frozen beef?
Use fully thawed beef for this slow cooker recipe. Thaw it in the refrigerator before seasoning and searing.
Can I make it without potatoes?
Yes. Leave them out and serve the beef and carrots over freshly prepared mashed potatoes, rice, or buttered noodles.
Do I need to turn the roast during cooking?
No. Keep the lid closed and let the slow cooker maintain steady heat.
Can I prepare it the night before?
Chop and refrigerate the vegetables, and measure the seasonings in advance. Keep the raw beef separately refrigerated. Sear the beef and assemble the slow cooker when you are ready to begin cooking.
