• 1 teaspoon dried thyme
• 1 teaspoon salt
• ½ teaspoon freshly ground black pepper
• 1 teaspoon Dijon mustard

For the Golden Potatoes & Carrots

• 1½ pounds (680 g) baby golden potatoes
• 3 cups baby carrots
• 1 large onion, diced
• 3 garlic cloves, minced
• 1 teaspoon Italian seasoning
• ½ teaspoon dried rosemary

For the Rich Mushroom Gravy

• 8 ounces (225 g) cremini or button mushrooms, sliced
• 3 tablespoons unsalted butter, divided
• 1½ cups beef broth, without added wine
• 2 garlic cloves, minced
• 1 tablespoon tomato paste
• 1 teaspoon Dijon mustard

For Garnishing

• 2 tablespoons fresh parsley, finely chopped

Instructions

Step 1: Prepare and Season the Beef

Start by patting the chuck roast dry with paper towels. If there are any large pieces of excess surface fat, trim them away, but leave the natural marbling that helps keep the beef tender.

In a small bowl, combine the garlic powder, onion powder, smoked paprika, dried thyme, salt, and black pepper.

Rub the seasonings all over the roast, then spread the Dijon mustard lightly across its surface.

Already, the combination of garlic, herbs, and spices gives the beef a wonderful savory aroma.

Step 2: Sear Until Beautifully Golden

Heat the olive oil in a large skillet over medium-high heat.

Carefully place the seasoned beef in the skillet and sear for approximately 3–4 minutes per side, until a deep golden-brown crust forms.

Let the meat develop its color without moving it too frequently.

This quick step adds a rich, roasted flavor that makes a noticeable difference in the finished dish.

Once browned, transfer the beef to a plate.

Step 3: Prepare the Vegetables

Wash the baby potatoes, cutting larger ones in half so they cook evenly.

Place the potatoes, baby carrots, diced onion, and 3 minced garlic cloves into the bottom of a 6-quart slow cooker.

Sprinkle with Italian seasoning, dried rosemary, salt, and black pepper.

Gently toss everything together.

As the vegetables cook, they’ll slowly absorb the delicious beef juices and garlic butter broth.

Step 4: Brown the Mushrooms in Butter

Return to the skillet used for the beef and reduce the heat to medium.

Melt 2 tablespoons of butter, then add the sliced mushrooms.

Cook for approximately 5–6 minutes, stirring occasionally, until the mushrooms become lightly golden and tender.

Once they develop those lovely browned edges, add the remaining 2 minced garlic cloves.

Cook for another 30 seconds, just until the garlic becomes fragrant.

The smell of buttery mushrooms and garlic is absolutely wonderful!

Remove the skillet from the heat.

Step 5: Mix the Savory Gravy Base

In a bowl, whisk together the beef broth, tomato paste, Dijon mustard, dried thyme, and optional balsamic vinegar.

The tomato paste adds richness and depth, while the mustard brings a subtle tangy note.

This simple mixture will slowly blend with the beef juices to create a delicious homemade gravy.

Step 6: Assemble the Slow Cooker

Place the seared beef roast over the seasoned potatoes and carrots.

Spoon the sautéed mushrooms and garlic over the beef, allowing some to fall around the vegetables.

Carefully pour the prepared broth mixture around the roast.

Cut the remaining tablespoon of butter into small pieces and scatter them over everything.

There’s no need to completely cover the beef with liquid. The ingredients will release additional moisture as they cook.

Step 7: Slow Cook Until Fork-Tender

Cover the slow cooker and cook on LOW for 7–8 hours or HIGH for 4–5 hours.

During this time, the chuck roast slowly becomes tender as its connective tissue softens. The potatoes develop a creamy texture, and the carrots become wonderfully sweet.

Try not to lift the lid too often.

When the cooking time is nearly finished, test the beef with a fork. It should pull apart easily.

If it still feels firm, continue cooking until tender.

Step 8: Make the Rich Mushroom Gravy

Carefully remove the cooked beef and vegetables from the slow cooker and place them on a warm serving platter.

In a small bowl, mix the cornstarch with the cold water until smooth.

Stir this mixture into the cooking liquid.

Cover and cook on HIGH for another 15–20 minutes, until the gravy thickens.

Alternatively, transfer the cooking juices to a saucepan and simmer with the cornstarch mixture until glossy and smooth.

Taste and adjust the seasoning if necessary.

Step 9: Bring Everything Together

Return the beef to the slow cooker or keep it on the serving platter.

Spoon the warm mushroom gravy generously over the roast, allowing some to settle around the potatoes and carrots.

The tender meat, buttery vegetables, and savory mushroom sauce should now look absolutely inviting.

Step 10: Garnish and Serve

Sprinkle freshly chopped parsley over the beef and vegetables.

Add a few fresh rosemary sprigs and a little cracked black pepper.

Slice the roast into generous portions or gently pull it apart with two forks.

Serve warm with plenty of mushroom gravy.

Presentation: A Beautiful Family-Style Roast

One of the best things about this meal is how naturally beautiful it looks.

For a cozy, rustic presentation, arrange the beef in the center of a large ceramic platter.

Surround it with golden baby potatoes, tender carrots, and buttery mushrooms.

Spoon the glossy garlic butter gravy over the beef, letting some flow naturally around the vegetables.

Finish with chopped parsley and a few rosemary sprigs.

For individual plates, serve a generous portion of beef alongside potatoes and carrots, then drizzle everything with warm gravy.

A fresh green salad, steamed green beans, or warm dinner rolls make lovely additions.

And don’t forget a little extra gravy on the side. It’s one of the best parts of the meal!

Little Tips for the Best Beef Roast

Choose a well-marbled chuck roast. This cut becomes wonderfully tender during slow cooking and develops a rich, comforting flavor.

Don’t skip the searing. Browning the beef before slow cooking adds a savory depth that makes the finished meal taste even better.

Brown the mushrooms first. Giving them a few minutes in butter enhances their earthy flavor before they join the roast.

Use baby golden potatoes. They hold their shape beautifully and develop a soft, buttery center.

Keep the carrots fairly large. Thick pieces hold up better during the long cooking process.

Thicken the gravy at the end. A cornstarch slurry creates a lovely smooth consistency without making the sauce overly heavy.

Try a creamy variation. Stir a tablespoon of heavy cream into the finished gravy for extra richness.

Don’t rush the beef. If the chuck roast doesn’t pull apart easily, give it more cooking time.
