French Onion Pot Roast

If you love French onion soup, you’ll love this French Onion Pot Roast! Caramelized onions and tender beef cook low and slow for the ultimate comfort meal.
This French Onion Pot Roast is one of my favorite comfort food dinners to make because my family absolutely loves it—especially my husband, who’s obsessed with anything with caramelized onions. Inspired by classic French onion soup, it slow-simmers with sweet onions and a rich, savory broth until the beef is fork-tender and practically falling apart. It’s meant to be a little brothy (just like French onion soup), which makes it perfect over mashed potatoes—or with cheesy Swiss toasts for dipping. And whether you want to make it in the slow cooker or in a Dutch oven, I’ve included both methods. The leftovers are just as good the next day.
- 2 tablespoons all purpose flour, or gluten-free flour mix
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- 2.5 lb boneless beef chuck roast, trimmed
- ½ tablespoon olive oil
- 4 cups onion, thinly sliced half moons (3 small or 2 medium)
- ⅓ cup sherry wine

- 1 package (1 ¼ ounces) dry onion soup mix
