How to Make French Onion Pot Roast

Preheat Oven to 300 Degrees F

Prep the Beef Roast

Pat your pound chuck roast dry with paper towels. Season generously with kosher salt, black pepper, and garlic powder.

Sear the Meat

In a large pot or Dutch oven, heat avocado oil over medium-high heat. Brown all sides of the roast until a golden crust forms. Remove and set aside.

Caramelize the Onions

Reduce to medium heat. Add butter, sliced onions, and a pinch of salt. Cook, stirring often, until deeply golden brown about 30 mins. Add garlic cloves and cook 1–2 minutes more.

Deglaze the Bottom of the Pan

Pour in red wine, scraping up all the browned bits from the bottom of the pot. Let it reduce by half.

Build the Cooking Liquid

Add beef broth, bay leaves, rosemary, and thyme. Return the roast to the pot, making sure it’s submerged about ¾ of the way.

Braise, Shred Beef, Add Cheese

Cover with the lid and braise in the 300 degree preheated oven for 3-4 hours until fork tender. Shred the beef and top with Gruyere cheese. Increase oven temp to 400 degrees, cover, place back in oven for 20-30 minutes until cheese melts.

• Pressure cooker: Cook on high pressure for about 70 minutes.
• Crockpot: Cook on low 8–9 hours.

Finish and Serve

Toast baguette slices. Garnish with chives. Serve with mashed potatoes, a green vegetable, and baguette slices to soak up the gravy.

Tips for Success

• Use a boneless beef chuck roast for the most tender pot roast — it has just the right amount of marbling and connective tissue.
• Always let the meat rest at room temperature for 20–30 minutes before searing.
• Don’t skip the deglazing step — those browned bits at the bottom of the pan are packed with flavor.
• For a thicker sauce, whisk in a cornstarch slurry (1 tbsp cornstarch + 2 tbsp water) at the end and simmer until slightly thickened.
• Store leftovers in an airtight container; the flavor gets even better the next day.
