Ingredients

For the Pot Roast:
3 lb (1.4 kg) beef chuck roast
4 cups (1 L) low-sodium beef broth
1.5 lbs (680 g) baby potatoes, whole (yellow or red)
1 lb (450 g) baby carrots, or large carrots cut into 2-inch pieces
1 large yellow onion, sliced
4 garlic cloves, minced
2 tbsp (30 ml) tomato paste
2 tbsp (30 ml) Worcestershire sauce
2 tbsp (30 ml) olive oil
1 tsp (2 g) dried thyme
1 tsp (2 g) dried rosemary, crushed
1 tsp (2 g) dried parsley (plus extra for garnish)
1 bay leaf
Salt and black pepper, to taste
Optional For Thickening the Gravy:
2 tbsp (16 g) cornstarch
2 tbsp (30 ml) cold water

Substitutions

If beef chuck roast isn’t available, brisket or bottom round roast can be used. These cuts become wonderfully tender with slow cooking.
Vegetable broth may be substituted for beef broth to reduce sodium or for a lighter flavor.
Red potatoes and Yukon gold potatoes both work well; if using larger potatoes, cut them into 2-inch chunks.
Baby carrots provide convenience, but whole carrots, peeled and cut, have a sweeter flavor.
For a gluten-free version, verify that your Worcestershire sauce is certified gluten-free and thicken with cornstarch in place of flour.
A splash of red wine can be used to deepen the flavor—add 1/2 cup (120 ml) wine and reduce the beef broth by the same amount.
Herbed seasonings can be swapped for Italian seasoning mix if you’re short on spices.

Equipment

Large slow cooker (at least 6-quart/5.7 L capacity)
Large skillet (for optional browning of the beef)
Tongs
Cutting board and knife
Measuring cups and spoons
Mixing bowl

Preparation

Begin by removing the beef roast from the refrigerator and allowing it to sit at room temperature for about 20-30 minutes for even cooking. Scrub the potatoes clean, and rinse the carrots if using them whole. Peel and slice the onion, and mince the garlic. Measure out your seasonings and liquids. If you prefer, pat the beef dry and season generously with salt and pepper for the most flavorful sear. If you wish to brown the roast for extra flavor, heat oil in a skillet and sear the beef on all sides for 3-4 minutes before adding to the slow cooker. Otherwise, you can place it directly into the slow cooker.

Step-by-Step Instructions

Brown the Beef (Optional but Recommended): Heat the olive oil in a large skillet over medium-high heat. Sear the beef chuck roast on all sides until deep golden brown—about 3 to 4 minutes per side. Transfer the roast to the slow cooker.
Add the Vegetables: Layer the sliced onions, whole baby potatoes, and baby carrots around and under the roast in the slow cooker.
Mix the Cooking Liquid: In a mixing bowl or measuring cup, combine the beef broth, tomato paste, Worcestershire sauce, minced garlic, dried thyme, rosemary, parsley, and bay leaf. Whisk to blend well.
Pour Over the Roast: Pour the broth mixture evenly over the roast and vegetables in the slow cooker. Gently toss the vegetables to coat with the liquid and seasonings. If you did not brown the beef, add the olive oil to the liquid now.
Cook Low and Slow: Cover the slow cooker with the lid and set to low for 8 hours, or high for 5 to 6 hours. For best results, use the low setting for the most tender meat. Avoid lifting the lid during cooking to retain heat and moisture.
Check for Doneness: After 8 hours, check that the beef shreds easily with a fork and the potatoes and carrots are fork-tender. If the roast is still tough, cook for an additional 30-60 minutes on low and recheck.
Optional Step – Thicken the Gravy: Remove 2 cups (480 ml) of cooking liquid and transfer to a small saucepan. Stir together 2 tbsp (16 g) cornstarch and 2 tbsp (30 ml) cold water in a bowl. Bring the liquid to a simmer over medium heat, then slowly whisk in the cornstarch slurry. Simmer until thickened. Pour back into the slow cooker and stir gently.
Shred and Serve: Remove the bay leaf. Using two forks, shred the pot roast into large chunks directly in the slow cooker, or transfer to a platter before shredding. Gently mix to combine beef with vegetables and gravy.
Garnish and Serve: Sprinkle with additional chopped parsley for a fresh finish. Serve hot directly from the slow cooker or transfer to a serving platter with a ladle of gravy on top.

Cooking Tips

Searing the beef before placing it in the slow cooker adds caramelization and enhances depth of flavor, but it’s not mandatory if you’re short on time.
Place potatoes and carrots at the bottom and sides, surrounding the roast, to ensure even cooking.
If your roast is too large for the slow cooker, cut it into big chunks for easier handling and even cooking.
Adjust the salt at the end of cooking, as some broths and Worcestershire sauces vary in sodium.
If you prefer a less soupy texture, remove the lid for the final 30 minutes of cooking on high to allow some liquid to evaporate and the gravy to thicken naturally.

Mistakes to Avoid

Do not use too lean a cut of meat. Chuck roast is ideal, as it breaks down into tender, flavorful shreds. Leaner cuts may turn out dry.
Avoid overfilling the slow cooker. Ingredients should not go above two-thirds full, or you risk uneven cooking.
Don’t lift the lid too often—each peek lets out heat and can increase the cooking time by up to 30 minutes.
Do not add potatoes in very small pieces, as they may become mushy. Keep them whole or in large chunks.
Don’t oversalt at the start; taste and adjust at the end since flavors concentrate as they cook.

Variations

Try adding parsnips, rutabaga, or celery with the carrots for extra root veggie flavor.
For a richer taste, add a splash of red wine or a tablespoon of balsamic vinegar to the broth mixture.
Use sweet potatoes in place of baby potatoes for a subtly sweet, earthy twist.
Toss in a handful of frozen peas 15 minutes before serving for a pop of color and texture.

Serving Suggestions

Serve this pot roast directly from the slow cooker alongside a crusty artisan bread or dinner rolls, perfect for soaking up the flavorful juices. Pair with a crisp green salad dressed simply with vinaigrette to balance the hearty meal. For drinks, a robust red wine or a warming mug of herbal tea complements the meal nicely. If you wish, finish with a light fruit dessert to round things out.

Storage

Cool leftovers to room temperature and transfer to airtight containers. Store in the refrigerator for up to 4 days. The flavors will deepen as it rests, making leftovers delicious. For longer storage, freeze cooled pot roast with veggies in freezer-safe containers for up to 3 months.

Reheating

Reheat pot roast and vegetables gently in a covered saucepan with a splash of broth over low heat, or in the microwave using a microwave-safe container. If reheating from frozen, thaw overnight in the fridge and proceed as above to retain tenderness and juiciness.

Make-Ahead Tips

All ingredients can be prepped the night before—trim and season the roast, chop onions, and prepare vegetables. Combine liquids and seasonings and refrigerate. In the morning, simply assemble everything in the slow cooker and start cooking. You can even sear the beef the night before for added flavor and convenience.

FAQ

Can I cook this pot roast on high?

Yes, you can cook on high for 5-6 hours, though low for 8 hours produces the most tender results. If time is short, high works in a pinch.

Should I peel the potatoes?

It’s not necessary if you’re using baby or thin-skinned potatoes. Just rinse them well. If using larger or thick-skinned potatoes, peeling is a good option for a softer texture.

Is it possible to make this with a different protein?

Yes, pork shoulder or chicken thighs also become tender in the slow cooker. Adjust cooking times as pork and chicken may require slightly less time.

How do I prevent my vegetables from becoming mushy?

Keep potatoes and carrots in large pieces and avoid overcooking. Placing them under or around the roast prevents them from getting too soft in the liquid.

What do I do if the gravy is too thin at the end?

Mix 2 tbsp (16 g) cornstarch with 2 tbsp (30 ml) cold water, whisk into simmering liquid on the stove to thicken, and then stir back into the pot roast in the slow cooker.

Can I double this recipe?

You can double the ingredients if your slow cooker is large enough (at least 8 quarts). Ensure the meat and vegetables are covered with liquid and check for doneness—larger quantities may need extra cooking time.

This classic pot roast is pure comfort food, perfect for feeding a family or having leftovers for busy nights.
