Ingredients

3 to 4 pounds beef chuck roast (well-marbled for tenderness)
2 teaspoons kosher salt, plus more to taste
1 teaspoon black pepper, freshly ground
1 tablespoon garlic powder or 3 cloves garlic, minced
1 large onion, sliced or chopped
4 carrots, peeled and cut into 2-inch chunks
1 to 1.5 pounds baby potatoes (Yukon gold or red), halved if large
2 tablespoons tomato paste
1 tablespoon Worcestershire sauce
1 cup beef broth (low-sodium preferred)
1 teaspoon dried thyme or 3 sprigs fresh thyme
1 teaspoon dried rosemary or 1 sprig fresh rosemary
2 bay leaves
2 tablespoons olive oil or neutral oil, for searing
2 tablespoons cornstarch (optional, for gravy)
2 tablespoons cold water (optional, for slurry)
Fresh parsley, chopped, for garnish (optional)

How To Make This Slow Cooker Pot Roast

Season the roast: Pat the beef dry. Rub all over with salt, pepper, and garlic powder (or minced garlic). Let it sit while you prep the veggies.
Prep the slow cooker: Add the onions, carrots, and potatoes to the bottom.
This creates a bed for the roast and keeps the vegetables flavorful and intact.
Sear the beef: Heat oil in a large skillet over medium-high. Sear the roast 3–4 minutes per side until deeply browned. This step builds flavor and helps the roast stay juicy.
Build the braising liquid: Reduce skillet heat to medium.
Stir in tomato paste and cook 1 minute. Add Worcestershire sauce and beef broth, scraping up browned bits. Pour this mixture over the vegetables in the slow cooker.
Add herbs and roast: Place the seared roast on top of the vegetables.
Add thyme, rosemary, and bay leaves. Cover with the lid.
Cook low and slow: Cook on Low for 8–10 hours or High for 4–5 hours, until the beef is fork-tender and easily shreds.
Taste and adjust: Remove the herbs and bay leaves. Taste the juices and add more salt or pepper if needed.
Make a quick gravy (optional): Transfer 2 cups of the cooking liquid to a saucepan.
Bring to a simmer. Stir together cornstarch and cold water, then whisk into the liquid. Cook 1–2 minutes until thickened. Season to taste
Serve: Slice or shred the roast. Spoon over vegetables and gravy. Garnish with parsley if you like.

Storage Instructions

Refrigerate: Cool completely, then store beef, vegetables, and gravy in an airtight container for up to 4 days.
Freeze: Portion into freezer-safe containers with some gravy to prevent drying.
Freeze up to 3 months. Thaw overnight in the fridge.
Reheat: Warm gently on the stovetop or in the microwave, adding a splash of broth if needed. Avoid boiling to keep the meat tender.

Health Benefits

Balanced meal in one pot: You get protein from the beef, fiber and vitamins from potatoes and carrots, and hydration from the broth-based sauce.
Iron and B vitamins: Beef chuck provides heme iron and B12, which support energy and red blood cell health.
Potassium and beta-carotene: Potatoes offer potassium for heart health, while carrots deliver beta-carotene for vision and immune support.
Customizable sodium: Using low-sodium broth and seasoning to taste helps you manage salt without losing flavor.

Common Mistakes to Avoid

Skipping the sear: Browning the meat is key for deep flavor.
It’s worth the extra 5–7 minutes.
Too little liquid: The roast needs enough moisture to braise. Aim for at least 1 cup of liquid in the slow cooker.
Overcrowding with veggies: Too many vegetables can steam rather than braise and may turn mushy. Stick to suggested amounts.
Cooking too hot, too fast: Low and slow makes the chuck roast tender.
High heat for too short a time can leave it tough.
Lifting the lid frequently: Each peek releases heat and adds cooking time. Trust the process.

Alternatives

Different cuts: Try bottom round or brisket if you can’t find chuck. Chuck is still the most forgiving choice for tenderness.
Veggie swaps: Use parsnips, turnips, or celery in place of some carrots and potatoes.
Mushrooms add a savory boost.
Flavor boosts: Add a splash of red wine with the broth, a teaspoon of Dijon mustard with the tomato paste, or a pinch of smoked paprika for depth.
Gluten-free: This recipe is naturally gluten-free if you use gluten-free Worcestershire. Thicken with cornstarch as directed.
Dairy-free: No dairy required. If you want extra richness, finish the gravy with a pat of dairy-free butter.
No-slow-cooker method: Use a Dutch oven.
Follow the same steps, then bake covered at 300°F (150°C) for 3–4 hours, until tender.

FAQ’s For Slow Cooker Pot Roast

Can I prep this the night before?

Yes. Season and sear the roast, chop the vegetables, and mix the braising liquid. Refrigerate everything separately.

In the morning, assemble in the slow cooker and start cooking.

Do I have to sear the beef?

No, but it’s highly recommended. Searing adds a rich, savory crust and deepens the overall flavor. If you’re short on time, you can skip it and increase the tomato paste by 1 teaspoon to boost umami.

How do I keep the vegetables from getting mushy?

Cut them into large chunks and place them on the bottom.

If your slow cooker runs hot, add potatoes in the last 2–3 hours. Waxy potatoes like Yukon gold hold up better than russet.

What if my roast isn’t tender after the recommended time?

Keep cooking. Toughness usually means it needs more time.

Ensure there’s enough liquid and cook on Low for another 1–2 hours, checking for fork tenderness.

Can I use frozen beef?

It’s best to thaw first for even cooking and proper searing. If you must cook from frozen, skip the sear and expect a longer cook time. Safety-wise, thawing in the fridge overnight is the safest route.

How can I reduce the fat?

Trim visible fat from the roast before cooking.

After cooking, let the juices sit for a few minutes, then skim off any fat from the top before making gravy.

What can I serve with pot roast?

It’s great as-is, but crusty bread, buttered noodles, or a simple green salad make a nice pairing. Leftovers are perfect for sandwiches or over mashed potatoes.

Can I double the recipe?

Yes, if your slow cooker is large enough. Don’t fill it more than three-quarters full.

You may need to add 30–60 minutes to the cook time.

Is there a way to make it spicier?

Add 1 teaspoon crushed red pepper or a chopped chipotle in adobo to the braising liquid. Taste and adjust as needed.
