Ingredients + Tips

The magic of this French Onion Pot Roast comes from simple, classic ingredients used the right way.

Beef Roast
A chuck roast is ideal for this recipe. It has enough marbling to stay juicy and becomes fork-tender after slow cooking. Avoid lean cuts, as they can dry out.

Onions
Yellow onions work best because they caramelize beautifully and develop natural sweetness. Slice them thinly so they soften and melt into the sauce.

Beef Broth
Use a good-quality beef broth or stock. Since this forms the base of the sauce, its flavor really matters.

Garlic & Herbs
Garlic adds depth, while thyme and bay leaf bring a subtle herbal note that complements the onions and beef.

Flour or Cornstarch (Optional)
A small amount helps thicken the sauce slightly, giving it that rich, gravy-like texture.

Pro Tips

• Take your time caramelizing the onions—this step builds the signature flavor.

• Sear the beef well before slow cooking for deeper taste.

• Deglaze the pan to capture all the browned bits.

Steps

Step 1: Caramelize the Onions
Heat oil or butter in a large Dutch oven over medium heat. Add the sliced onions with a pinch of salt and cook slowly, stirring occasionally, until deeply golden and soft. This can take 20–30 minutes, but it’s worth every minute.

Step 2: Sear the Beef
Season the roast generously with salt and pepper. Remove the onions from the pot and set aside. Increase heat and sear the beef on all sides until well-browned.

Step 3: Build the Base
Add garlic to the pot and cook briefly. Pour in beef broth to deglaze the pan, scraping up any browned bits.

Step 4: Assemble & Cook
Return the onions to the pot, add herbs, and place the roast back in. Cover and cook low and slow until the beef is fork-tender.

Step 5: Finish
Remove the roast and let it rest. Simmer the sauce slightly if needed, then slice or shred the beef and serve with the onions and sauce spooned over the top.

Variations

This recipe is flexible and easy to adapt.

• Slow Cooker: After searing, transfer everything to a slow cooker and cook on low for 8 hours.

• Instant Pot: Use the sauté function for onions and beef, then pressure cook until tender.

• Cheesy Twist: Serve with melted Gruyère or Swiss cheese on top.

• Vegetable Add-Ins: Add carrots or mushrooms for extra heartiness.

• Wine-Enhanced: Deglaze with a splash of dry white wine for deeper flavor.

Storage & Reheating

Refrigeration:
Store leftovers in an airtight container for up to 4 days.

Freezing:
Freeze the beef and onions in sauce for up to 3 months.

Reheating:
Reheat gently on the stovetop or in the microwave, adding broth if the sauce thickens too much.
