French Onion Beef Stew is a hearty, flavorful twist on classic French onion soup, with tender beef, caramelized onions, and a rich savory broth. It's perfect for an easy, comforting meal.
Thinly slice the onions using a sharp knife or mandoline.
Add the onions and garlic cloves to an oven-safe cast iron dutch oven. Pour 4 tablespoons olive oil over the onions, sprinkle with the salt, then toss to coat.
Cover and bake for 1 hour. Remove from the oven and turn the heat on the oven down to 350°F.
Remove the onions and garlic from the dutch oven and place them on a rimmed plate or a cutting board with grooves, as liquid will come out of the onions and garlic.
Place the dutch oven on the stove over high heat.
Toss the cubed beef with the french onion seasoning.
Heat 2 tablespoons olive oil in the dutch oven. Once the oil is hot, add the chuck roast and sear the pieces for about 4-6 minutes, or until browned on all sides. Use a slotted spoon to remove the beef from the pot and set it aside with the onions and garlic.
Pour ¼ cup beef stock into the pot and stir to deglaze the bottom of the pot and scrape up any browned bits.
Sprinkle the flour evenly over everything in the pot, stir to combine, and cook for 1 minute.
Add the remaining 7 ¾ cups beef stock and 2 tablespoons Worcestershire sauce to the pot. Stir to combine everything, turn the heat on the stove up to high, and bring the stock to a boil.
Add the seared pieces of beef back to the pot, along with the onions and garlic. Add the potatoes, fresh thyme, and bay leaves.
Cover the pot with a lid, or tightly with a piece of aluminum foil, and transfer it to the oven for 2 hours.
Remove the soup from the oven and use tongs to remove and discard the bay leaves and thyme sprigs.
Optional way to serve the soup
Heat the oven to broil on high and arrange a rack in the middle of the oven.
Slice a half loaf of french bread, then place the slices on a baking sheet and spray with cooking spray, or brush with melted butter. Place under the broiler for 1-2 minutes, or until lightly toasted. Remove the bread from the oven.
Ladle the soup into oven-safe bowls and top each bowl with a slice of toast and shredded gruyere cheese. Place on a baking sheet and under the broiler in the oven for 1-2 minutes, or until the cheese is melted and bubbling.
Notes
You can make this recipe ahead of time. After cooking the beef stew for 2 hours at 350°F, simply turn the oven to warm and leave the stew, covered in the oven, for up to 2 hours. You can also transfer it to a slow cooker set to warm.
You can cook the beef stew on the stove, instead of the oven, if you prefer. Simply cover the pot, set the stovetop temperature to medium-low heat and allow the stew to simmer for 2 hours on the stove.
To make this recipe gluten free, use cornstarch instead of flour to thicken the broth. Cornstarch is a stronger thickening agent than flour, so you’ll only need 2 tablespoons of cornstarch.
If you would like to add another layer of flavor to this french onion beef stew, you can replace one cup of the beef broth with dry red wine, like a cabernet sauvignon.
Store leftover beef stew in an airtight container in the fridge for up to 5 days. To reheat the stew, add it to a pot on the stove over medium-high heat. Bring it to a simmer, then stir the stew occasionally for 5-7 minutes on the stovetop. You can also reheat one portion of the stew in a microwave-safe bowl, covered in the microwave for 2-3 minutes.
You can also store prepared beef stew in the freezer for up to 6 months. You’ll want to let the stew cool down to room temperature, then transfer it to a freezer-safe storage container. Freeze the stew for up to 6 months. To defrost, I recommend transferring the stew from the freezer to the refrigerator for 24 hours. You can then reheat the stew in a large pot on the stove over medium-high heat for 15-20 minutes.
