Ingredients
- Beef Roast – I love using chuck roast, but arm, round or rump also work.
- Oil – for searing the beef.
- Butter – for sautéing the onions
- Onion – white onions are traditional, but I typically have yellow on hand.
- Seasonings – salt, pepper, garlic
- Wine – white wine is traditional, but red wine is amazing as well.
- Balsamic Vinegar – I love the acidic component it adds.
- Worcestershire Sauce – adds a bit of extra flavor.
- Gruyere Cheese – for serving
- Cornstarch – for thickening the gravy.
How to Make French Onion Pot Roast
- Season chuck roast liberally with salt and pepper. You may need to cut down the roast into smaller pieces to fit in the dutch oven to sear. I cut mine into 4 large pieces, removing extra fat.
- Add oil to a 5 quart dutch oven and heat over medium heat. Add roast and sear on all sides. Remove seared meat from dutch oven and set aside for later.
- Preheat oven to 325.
- Add butter to dutch oven. Once hot and melted, add the onions, salt and pepper, and allow them to cook down and deeply caramelize for about 20 to 25 minutes, stirring frequently, until the onions become very dark, soft and jammy.
- Add in the garlic and thyme, wine, balsamic, Worcestershire, and allow it to bubble up and reduce for about 30 seconds. Then pour in the beef stock and whisk or vigorously stir to blend in and combine until smooth. Allow the French onion sauce to simmer to 5 minutes.
- Nestle the seared roast into the onion sauce, spooning onion mixture on top of roast.
- Place into oven and bake for 3-4 hours.
- Remove roast from oven and pull apart meat with two forks.
- In a small bowl combine cornstarch with 1 tbsp water and pour into roast mixture to thicken the sauce.
- Serve mixture over mashed potatoes and a sprinkle of shredded gruyere cheese.
