How to Make French Onion Pot Roast

Caramelize the onions. In a large Dutch oven over medium-low heat, add the sliced onions. Cook for 20-25 minutes, stirring occasionally and scraping up the browned bits from the bottom, until the onions are very soft and golden brown.
Add the garlic and cook for about 30 seconds. Set onions aside.
Season the roast. Pat the chuck roast dry and season all sides with salt and black pepper.
Sear the beef. Heat olive oil in a large Dutch oven over medium-high heat. Add the roast and sear for about 4-5 minutes per side, until deeply browned. Transfer the roast to a plate.
Deglaze with wine. Pour in the white wine. Scrape the bottom of the Dutch oven to loosen all the browned bits. Simmer for 3-4 minutes.
Build the broth. Stir in the beef broth and Worcestershire sauce. Return the chuck roast and onions to the Dutch oven. Add the fresh thyme and bay leaves.
Cover and bake. Bake at 325°F for 3-3 ½ hours, or until the roast is fork-tender and pulls apart easily. Remove the thyme stems and bay leaves. Keep covered and let the roast rest while making the Gruyère toasts.

Bake for 4 to 6 minutes, or until the bread is lightly crisp and golden around the edges. Remove the bread from the oven and sprinkle each slice with Gruyère cheese. Return the baguette slices to the oven and bake for 3 to 4 minutes, or until the cheese is melted and bubbly.

FAQ

What is the best cut of beef for French onion pot roast?

Chuck roast is the best choice because it has enough fat and connective tissue to become tender and flavorful during a long, slow braise. A 3-pound chuck roast is ideal for this recipe.

What kind of wine should I use?

Use a dry white wine such as Sauvignon Blanc, Pinot Grigio, or an unoaked Chardonnay. Avoid sweet wines because the caramelized onions already add plenty of sweetness.

Can I make French onion pot roast without wine?

Yes. Replace the white wine with an equal amount of additional beef broth. For a little acidity, you can add a small splash of balsamic vinegar.

Can I make this in the slow cooker?

Yes. Caramelize the onions and sear the chuck roast on the stovetop first, then transfer everything to the slow cooker. Cook on LOW for 8-9 hours, or
HIGH for 4-5 hours. I strongly prefer LOW for chuck roast-it tends to come out more tender.

Do I have to caramelize the onions first?

I recommend it. Slowly cooking the onions before braising develops the deep, sweet onion flavor that makes the recipe taste like French onion soup. Adding raw onions directly to the roast won’t give you quite the same flavor.

What can I serve with French onion pot roast?

The Gruyère baguette toasts are perfect for soaking up the onion broth. You can also serve the roast with mashed potatoes, roasted potatoes, egg noodles, or a simple green vegetable side.

How long do leftovers last?

Store leftover pot roast in an airtight container in the refrigerator for up to 3-4 days.
