Ingredients

• 3 lbs beef chuck roast
• 3 large yellow onion
• 4 medium garlic cloves
• 3 tbsp olive oil
• 2 cups beef broth
• 2 tbsp unsalted butter
• 1 tsp dried thyme
• 1 tsp dried rosemary
• 1.5 tsp salt
• 1 tsp black pepper
• 1 tbsp cornstarch
• 2 tbsp water

Directions

Step 1

Preheat your oven to 325°F (160°C).

Step 2

Season the beef chuck roast generously on all sides with 1 tsp of salt and 1 tsp of black pepper.

Step 3

In a large oven-safe pot or Dutch oven, heat 2 tbsp of olive oil over medium-high heat until shimmering.

Step 4

Sear the beef roast in the pot for 3-4 minutes per side until a deep brown crust forms. Remove the beef and set it aside.

Step 5

Add the remaining 1 tbsp of olive oil and unsalted butter to the pot. Once the butter is melted, add the thinly sliced yellow onions and cook for 8-10 minutes over medium heat, stirring frequently, until the onions are golden and caramelized.

Step 6

Mince the garlic cloves and add them to the pot with the onions. Cook for 1 minute until fragrant.

Step 7

Deglaze the pot by pouring in 1/2 cup of beef broth and scraping up any browned bits at the bottom of the pot.

Step 8

Place the beef roast back into the pot with the onions. Sprinkle the dried thyme and rosemary on the beef.

Step 9

Pour the remaining 1.5 cups of beef broth around the roast. Cover the pot with a tight-fitting lid or aluminum foil.

Step 10

Transfer the pot to the preheated oven and roast for 2.5 to 3 hours, or until the beef is tender and easily shreds with a fork.

Step 11

Remove the pot from the oven and transfer the beef to a serving platter. Allow it to rest for 10 minutes.

Step 12

Strain the cooking liquid into a medium saucepan, discarding the solids. Heat the liquid over medium heat.

Step 13

In a small bowl, mix the cornstarch with 2 tbsp of water to create a slurry. Slowly whisk the slurry into the hot cooking liquid to thicken it into a gravy.

Step 14

Slice or shred the beef roast and serve it with the onion gravy drizzled generously over the top. Enjoy!
