Why You’ll Love This Recipe

I’m a huge fan of meals that warm both the kitchen and the soul — and this French Onion Pot Roast does exactly that. The onions caramelize low and slow until they’re sweet and jammy, creating a deeply flavorful base. From there, the roast braises until melt-in-your-mouth tender, and I like to finish it with bubbling cheese under the broiler. Whether I’m making this for a weekend dinner or prepping it ahead for a special gathering, it always delivers. Plus, it smells amazing as it cooks.

ingredients

(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)

3 pounds chuck roast
Fine sea salt, to taste
Fresh ground black pepper, to taste
2 tablespoons avocado oil (or other neutral cooking oil)
2 tablespoons unsalted butter
3 large yellow onions, thinly sliced (about 6–7 cups)
4 cloves garlic, minced
3 cups beef broth (low sodium or beef stock)
2 tablespoons Worcestershire sauce
2 bay leaves
2 teaspoons dried thyme
1 teaspoon dried oregano
2 tablespoons cornstarch
4 tablespoons water (for slurry)
Optional Cheese Topping: 2 cups provolone or Gruyère, shredded
Serve With: fresh parsley, chopped; thick slices of baguette or crusty French bread, toasted

directions

I start by patting the chuck roast dry with paper towels, then seasoning it generously with salt and pepper on all sides.
In a Dutch oven over medium-high heat, I heat the avocado oil and sear the roast on all sides for about 4–5 minutes per side, until it’s nicely browned. Then I remove it and set it aside.
I reduce the heat to medium-low, add butter, and once it melts, I add the sliced onions. I cook them slowly, stirring occasionally, for at least 30–45 minutes until they’re caramelized and soft.
In the last 30 seconds of the onion cooking, I stir in the garlic until it’s fragrant.
I raise the heat to medium-high and add beef broth, Worcestershire sauce, bay leaves, thyme, and oregano. I bring it all to a simmer, then taste and adjust the seasoning.
I return the roast and any juices to the pot and bring it back to a gentle simmer.
Then I reduce the heat to low, cover the pot, and let it simmer gently on the stovetop — or I transfer it to a 300°F oven — for 3½ to 4 hours, until the beef is fork-tender. If the liquid reduces too much, I add a splash of broth or water.
Once the beef is tender, I remove the roast and discard the bay leaves. I whisk the cornstarch and water together, then whisk it slowly into the liquid to thicken it over 1–2 minutes.
I return the roast to the pot and use two forks to shred the beef into the sauce, stirring gently to mix it all together.
For the finishing touch, I sprinkle the shredded cheese on top and place it under the broiler for 2–5 minutes, watching closely until the cheese is melted and bubbly.
I garnish with chopped parsley and serve it hot with toasted baguette slices.

Variations

I like switching things up from time to time. Here are a few tweaks I make depending on what I have on hand:

I sometimes swap out part of the beef broth for red wine to add richness and depth.
For the cheese, I use Gruyère when I want that classic French onion flavor or provolone for a smooth melt. Mixing cheeses also works beautifully.
When I want a lower-carb option, I skip the bread and serve it with roasted vegetables instead.
I’ve also made it in a slow cooker — after caramelizing the onions, everything goes into the cooker on low for 8 hours.

storage/reheating

Leftovers keep beautifully. I refrigerate them in an airtight container for up to 4 days and reheat gently on the stovetop or in the microwave.

If I want to freeze it, I let the pot roast cool completely (without adding cheese) and store it in a freezer-safe container for up to 3 months. I thaw it overnight in the fridge before reheating, and then I add the cheese topping fresh before serving.

To reheat with cheese, I sometimes place it back under the broiler just like the first time.

FAQs

How do I know when the onions are properly caramelized?

I look for a deep golden-brown color and soft, jammy texture. It usually takes 30–45 minutes over low heat, and I stir often to prevent burning.

Can I make this in a slow cooker?

Yes, after searing the meat and caramelizing the onions, I transfer everything to a slow cooker and cook on low for 8–9 hours or until the meat is tender.

What’s the best cut of meat for this recipe?

Chuck roast works best — it becomes incredibly tender after long, slow cooking and has enough fat to stay juicy and flavorful.

Can I skip the cheese topping?

Absolutely. I like the cheesy finish, but the roast is still full of flavor without it. If I’m watching calories or keeping it dairy-free, I leave it off.

What can I serve with this pot roast?

Toasted baguette slices are my favorite, but I also serve it with mashed potatoes, polenta, or even over egg noodles for a hearty meal.

This French Onion Pot Roast is a true comfort food classic — deeply savory, rich, and incredibly satisfying. Whether I’m hosting guests or just feeding the family, it never fails to impress.
