Fork-Tender Slow Cooker Pot Roast with Rich Gravy

This Slow Cooker Pot Roast is classic comfort food made effortless. Chuck roast is cut into large pieces, seasoned, seared, and slow cooked with onions, carrots, mushrooms and baby potatoes in a savory beef gravy until the meat is fork-tender. The cooking liquid is thickened with a simple cornstarch slurry right in the slow cooker, creating a rich, spoonable sauce that brings everything together. Instant Pot instructions are included for a faster option.

There’s something especially satisfying about a slow-cooked pot roast with gravy and chunky vegetables on a chilly evening. This slow cooker pot roast delivers deep, homey flavor while letting the slow cooker do most of the work.

The recipe begins on the stovetop to build extra flavor. Searing the chuck roast develops a caramelized crust, then mushrooms, garlic and tomato paste are cooked briefly to concentrate their taste. The pan is deglazed with beef broth, coconut aminos (or an alternative), and Dijon mustard to form a flavorful cooking liquid that seeping into the meat and vegetables as they cook.

Vegetables soften but keep their shape when cut into large pieces. After slow cooking, the pot juices are thickened into a gravy and ladled over the roast and vegetables for a complete, satisfying meal. This dish is family-friendly, makes great leftovers, and often tastes even better the next day.

Recipe ingredients

• Carrots: Cut into large chunks so they remain firm after slow cooking.
• Baby gold potatoes: Halve larger potatoes; small ones can be left whole.
• Beef broth: Forms the base of the cooking liquid and eventual gravy.
• Coconut aminos: Adds savory depth; substitute Worcestershire, tamari or soy sauce if preferred.

• Cornstarch: Mixed with cold water or stock to make a slurry for thickening the gravy.

How to make crock pot pot roast

This pot roast requires a little attention at the start to build flavor, then it cooks slowly in the crock pot. Browning the beef before slow cooking is an important step: it adds caramelized flavor that enhances the final gravy.

Instant Pot variation (optional)

If you’re short on time, use an Instant Pot. Follow these steps:

1. Use Sauté mode to sear the beef in batches, then remove it.
2. Cook the mushrooms, then add tomato paste and garlic and cook briefly.
3. Deglaze with beef stock, coconut aminos and Dijon, scraping up any browned bits.
4. Return the beef to the pot, add the vegetables, and pressure cook on HIGH for 35 minutes. Allow a 10-minute natural release.
5. Remove the beef and vegetables. If the beef isn’t quite tender, pressure cook for an additional 10 minutes.
6. Switch back to Sauté, bring the liquid to a simmer, stir in the cornstarch slurry and cook until thickened. Season to taste and serve.

Note: The slow cooker gives slightly more tender meat and a more developed gravy, while the Instant Pot is best when you need dinner sooner.

Make-ahead “dump and go” option (great for busy mornings)

Prepare through the deglazing step the night before to save time:

1. Sear the beef and cook the mushrooms with tomato paste and garlic.
2. Deglaze with beef stock, coconut aminos and Dijon, scraping up the fond.
3. Let the mixture cool, then refrigerate in an airtight container for up to 24 hours.
4. In the morning, transfer everything to the slow cooker, add the vegetables, and cook as directed.

Serving suggestions

This pot roast is hearty on its own, but here are ideas to complete the meal:

• Spoon the roast and gravy over mashed potatoes or buttered egg noodles.
• Serve with crusty bread or focaccia to soak up extra gravy.
• Balance the rich main dish with a light salad or steamed greens.

Recipe notes

• Pro tip: Browning the beef is a small step that makes a big flavor difference in the final dish.
• Make-ahead friendly: Prepping components the night before speeds up busy mornings.
• Customizations: Omit mushrooms or swap in parsnips, turnips or extra carrots according to preference.
• Storage & freezing: Refrigerate leftovers up to 4 days or freeze up to 3 months. For best texture when freezing, omit the potatoes and freeze the meat and gravy separately.

Slow Cooker Pot Roast

Servings: 6 | Prep time: 10 mins | Cook time: 4–8 hours (depending on setting)

Ingredients

• 4 lbs. chuck roast, cut into 4 large chunks
• 1.5 teaspoons sea salt
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon black pepper
• 2 tablespoons avocado oil (or other high heat oil)
• 8 ounces mushrooms, sliced (optional)
• 2 tablespoons tomato paste
• 3 cloves garlic, minced
• 2 tablespoons coconut aminos (or Worcestershire, tamari, soy)
• 1 tablespoon Dijon mustard
• 2 cups beef broth
• 1 large yellow onion, halved and sliced
• 4 large carrots, peeled and cut into 1.5″ chunks
• 1 lb. baby gold potatoes, halved if large
• 2 tablespoons cornstarch
• 2 tablespoons cold water or beef stock (for slurry)
• Salt and freshly ground black pepper, to taste

Instructions

1. Pat the chuck roast dry and season all over with sea salt, garlic powder, onion powder and black pepper.
2. Heat oil in a large skillet over medium-high heat. Sear the roast pieces in batches until browned on all sides, then transfer them to the slow cooker.
3. In the same skillet, sauté mushrooms until they release their juices and begin to brown. Add tomato paste and garlic and cook for about 30 seconds. If the pan looks like it’s burning, add a splash of water and scrape up the browned bits.
4. Pour beef broth into a measuring cup, whisk in coconut aminos and Dijon mustard, then pour into the skillet. Scrape up any fond and pour the mixture over the roast in the slow cooker. (At this point you can cool and refrigerate for up to 24 hours for the make-ahead option.)
5. Add the onion, carrots and potatoes on top of the beef. Cover and cook on LOW for 8+ hours or on HIGH for 4–6 hours, until the meat is fork-tender.
6. Use a slotted spoon to transfer the beef and vegetables to a platter and keep warm. Turn the slow cooker to HIGH and bring the remaining liquid to a simmer.
7. Whisk cornstarch with cold water or stock until smooth. Slowly add the slurry to the simmering liquid, stirring until the gravy thickens, 10–15 minutes. Season well with salt and pepper.
8. Slice or shred the beef as desired, return to the platter with the vegetables, and spoon gravy over the top. Garnish with chopped parsley if desired and serve.
