Savory French Onion Pot Roast

Ingredients

3-4 pounds chuck roast or brisket
2 tablespoons olive oil
2 medium onions, thinly sliced
4 cloves garlic, minced
1 cup beef broth
1 cup additional beef broth
2 tablespoons soy sauce (for extra depth of flavor)
2 teaspoons dried thyme
1 teaspoon dried rosemary
1 bay leaf
Salt and pepper, to taste
1 tablespoon cornstarch (optional, for thickening)
Fresh parsley, chopped (for garnish)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat your oven to 325°F (163°C).
Heat the olive oil in a large Dutch oven or heavy pot over medium-high heat. Season the roast generously with salt and pepper.
Brown the roast on all sides, about 4-5 minutes per side, until it has a nice sear. Once browned, remove the roast from the pot and set aside.
In the same pot, add the sliced onions and cook over medium heat until they begin to soften and caramelize, about 15-20 minutes, stirring occasionally.
Add the minced garlic and cook for an additional minute until fragrant.
Pour in the beef broth, additional broth, and soy sauce, scraping up any brown bits from the bottom of the pot. Stir in the thyme, rosemary, bay leaf, and more salt and pepper to taste.
Return the browned roast to the pot, making sure it’s partially submerged in the liquid. Cover the pot with a lid and place it in the preheated oven.
Roast for 3-4 hours, or until the roast is fork-tender and easily shreds with a fork. You can check the roast’s tenderness after 3 hours and adjust cooking time as needed.
Once done, remove the roast from the pot and let it rest for 10-15 minutes before slicing or shredding.
If you prefer a thicker sauce, remove the bay leaf, and bring the liquid to a simmer on the stovetop. Mix the cornstarch with a little water to form a slurry, then whisk it into the sauce to thicken. Let it simmer for a few more minutes until the sauce reaches your desired consistency.
Serve the pot roast with the savory onion sauce and garnish with fresh parsley.
