Why You’ll Love This Recipe

I love how this pot roast fills the house with the most incredible aroma while it slowly cooks. The onions caramelize beautifully, creating a sweet and savory base that soaks into the beef as it braises. It’s one of those meals that feels elegant and rustic at the same time. I can serve it for a Sunday dinner or make it ahead to enjoy during the week — either way, it always hits the spot.

ingredients

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

3 Tbsp extra virgin olive oil (divided)
3 lb boneless chuck roast (pot roast)
1 tsp fine sea salt
1 tsp freshly ground black pepper
3 lbs yellow onions (about 8 medium‑large)
2 cloves garlic, finely chopped
1 Tbsp pure maple syrup or brown sugar
1 Tbsp all‑purpose flour (or gluten‑free AP flour)
3½ cups beef stock
1 sprig fresh rosemary
1 bay leaf

directions

I preheat a Dutch oven over medium heat and add 1 tablespoon of olive oil. I season the pot roast with half the salt and pepper.
I brown the roast on all sides, about 10 to 12 minutes total. Once it’s nicely seared, I remove it from the pot and set it aside.
I slice the onions and add them to the pot with the remaining olive oil. I season them with the rest of the salt and pepper and cook for about 5 minutes until they turn translucent.
I reduce the heat to medium-low and let the onions caramelize slowly for around 20 minutes, stirring now and then.
I stir in the garlic and maple syrup, letting everything cook together for another 7 to 8 minutes.
I sprinkle in the flour and stir until the onions are coated. Then I slowly pour in the beef stock, scraping up any bits from the bottom.
I return the roast to the pot, making sure it’s mostly covered with the liquid. I tuck in the rosemary and bay leaf and bring the mixture to a simmer.
I cover the pot and transfer it to a 300°F oven for 3 hours, leaving it undisturbed.
After 3 hours, I flip the roast, pull it apart slightly with forks, then cover it again and bake for another 30 to 45 minutes until it’s incredibly tender.
I take it out, let it rest uncovered for a bit, and then serve it hot with mashed potatoes, buttered noodles, or creamy polenta.

Variations

When I want to change things up, I like to add a few mushrooms to the pot with the onions for extra umami. Sometimes I swap maple syrup for brown sugar depending on what I have. If I’m going gluten-free, I just use a 1:1 gluten-free flour blend to thicken the onions. And if I feel like making it more herbaceous, I’ll toss in a few thyme sprigs along with the rosemary.

storage/reheating

I let leftovers cool completely before storing them in an airtight container. They keep in the fridge for up to 4 days and reheat well on the stovetop over low heat. If the sauce thickens too much, I just add a splash of broth or water. This roast also freezes beautifully. I portion it into freezer-safe containers and thaw it overnight in the fridge before reheating — the flavors deepen even more the next day.

FAQs

What cut of beef works best for this recipe?

I always use a boneless chuck roast. It has enough marbling to stay moist during the long braise and turns fork-tender every time.

Can I prep this ahead of time?

Yes, I often make it a day in advance. The flavors get even better after sitting overnight. I just reheat it slowly on the stovetop or in the oven at 300°F.

What sides go well with this pot roast?

Mashed potatoes are my go-to, but I also love it with egg noodles, polenta, or even crusty bread to soak up the juices.

Do I have to use a Dutch oven?

A heavy oven-safe pot with a lid works just as well. I’ve also made it in a slow cooker by searing the beef and onions first, then cooking everything on low for 8–10 hours.

How do I know when the beef is ready?

I check if it shreds easily with two forks. If it still feels tough, I give it another 30 minutes in the oven — low and slow is the key.

Conclusion

This French onion pot roast is one of my favorite comfort meals to make at home. It’s deeply flavorful, incredibly tender, and so satisfying. The simple ingredients come together into something special — a dish that feels both rustic and refined. Whether I’m serving it for a family dinner or freezing it for later, it’s always a winner in my kitchen.
