Ingredients

Here’s what you’ll need to bring this hearty pot roast to life:

For the Roast:

• 3 tablespoons extra virgin olive oil, divided
• 3 lb boneless pot roast (chuck)
• 1 teaspoon fine sea salt
• 1 teaspoon freshly ground black pepper

For the Onions and Gravy:

• 3 lbs yellow onions, thinly sliced (about 8 medium-large)
• 2 cloves garlic, finely chopped
• 1 tablespoon pure maple syrup (or substitute brown sugar)
• 1 tablespoon all-purpose flour (or gluten-free AP flour)
• 1 cup red wine (or substitute with additional beef stock)
• 2 1/2 cups beef stock
• 1 sprig fresh rosemary
• 1 bay leaf

Step-by-Step Instructions

Step 1: Prepare the Pot Roast

Start by patting your pot roast dry with paper towels—this helps it sear better. Season all over with salt and pepper.

Heat 2 tablespoons olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Once the oil is hot and shimmering, sear the roast for 4–5 minutes per side until deeply browned. This step builds foundational flavor in the final dish.

Transfer the roast to a plate and set aside.

Step 2: Caramelize the Onions

Reduce heat to medium and add the remaining 1 tablespoon olive oil to the pot. Add the sliced onions and stir to coat them in the oil and leftover beef drippings.

Continue cooking the onions, stirring occasionally, for about 25–30 minutes, or until they become deep golden brown. Don’t rush this step—slow caramelization brings out their natural sweetness.

About halfway through cooking, add the maple syrup or brown sugar to help enhance the color and sweetness.

Step 3: Build the Flavor Base

Once the onions are beautifully caramelized, add the chopped garlic and cook for 1–2 minutes until fragrant.

Sprinkle in the flour, stirring well to coat the onions. Cook for another minute to remove the raw flour taste—this will help thicken the sauce.

Slowly pour in the red wine, scraping up any browned bits from the bottom of the pan with a wooden spoon. Let it simmer for 2–3 minutes to reduce slightly.

Step 4: Add Broth and Herbs

Pour in the beef stock, and return the seared roast to the pot. Nestle the rosemary sprig and bay leaf in the broth.

Bring the liquid to a gentle simmer, then cover the pot with a tight-fitting lid.

Step 5: Slow Cook Until Tender

Transfer the covered pot to a preheated oven at 325°F (165°C) and let it cook for 3–3.5 hours, or until the roast is fork-tender and the onions have melded into a rich, savory sauce.

Halfway through the cooking time, you can flip the roast if you like, although it’s not necessary.

Step 6: Finish and Serve

Remove the pot from the oven and discard the rosemary and bay leaf. Taste the gravy and adjust seasoning with salt and pepper if needed.

Slice or shred the beef, then spoon the luscious French onion gravy over the top.

Serve with creamy mashed potatoes, crusty bread, buttered noodles, or roasted root vegetables for the ultimate comforting plate.

Pro Tips for Perfect French Onion Pot Roast

• Use a Dutch oven: A heavy, oven-safe pot retains heat evenly and creates the ideal environment for long braising.
• Sear thoroughly: Don’t skip or rush the browning stage—it locks in juices and creates complex flavor.
• Take your time with the onions: True caramelization takes at least 25 minutes. Stir occasionally, and if they start sticking too much, add a splash of water to deglaze the pan.
• Deglaze with wine: Red wine adds depth and body to the sauce. A dry wine like cabernet sauvignon or merlot works beautifully.
• Make it ahead: This pot roast actually tastes better the next day as the flavors develop further. It’s a great make-ahead option for entertaining or meal prep.

Variations

• Make it gluten-free: Swap all-purpose flour for a 1:1 gluten-free flour blend.
• Try it in a slow cooker: After caramelizing the onions on the stove, add everything to a slow cooker and cook on low for 8 hours or high for 4–5 hours.
• Pressure cooker shortcut: Use an Instant Pot to cut the total time down. After searing and sautéing the onions, pressure cook everything on high for 60–70 minutes, followed by a natural release.
• Add mushrooms: Stir in sliced mushrooms during the last hour of cooking for an earthy twist.
• Low-carb side ideas: Serve with mashed cauliflower or roasted broccoli for a lighter take.

Frequently Asked Questions

Can I use a different cut of beef?

Yes. While chuck roast is ideal for its marbling and tenderness after braising, you can also use brisket, bottom round, or shoulder roast. Just make sure to cook long enough to become fork-tender.

I don’t have red wine. What can I use instead?

You can substitute the wine with more beef stock and add a splash of balsamic vinegar or Worcestershire sauce for a hint of acidity and depth.

Can I cook this on the stovetop instead of the oven?

Absolutely. Keep it on a low simmer, covered, for about 3 hours, checking periodically to ensure the bottom doesn’t burn. Stir occasionally.

Can I make this dish in advance?

Yes, and it actually tastes even better the next day! The flavors deepen overnight, and the roast is easier to slice once chilled.

How should I store leftovers?

Store leftovers in an airtight container in the refrigerator for up to 4 days. You can also freeze portions for up to 3 months.

What sides go best with French onion pot roast?

Mashed potatoes, crusty bread, egg noodles, polenta, or roasted vegetables make excellent pairings. Don’t forget a green salad or steamed green beans to balance the richness.
