The gooey, bubbly gruyere cheese melted over French Onion soup is the best part. Yes, we all love the beefy broth and caramelized onions, but that cheesy toast is where it’s at. If you want to keep French Onion Pot Roast budget friendly, swap the gruyere for a less expensive Swiss or provolone. Check out the deli case too, sometimes they will have fancy cheeses, like gruyere or Emmental, for a fraction of the cost in portions just big enough for this recipe!



French Onion Pot Roast is hearty, more like a stew than a soup or a pot roast. The beef becomes so tender while cooking so you can break it apart easily before toasting the bread and cheese. If you are serving a small group, set half of your French Onion Pot Roast aside for leftovers the next day. Add the sliced baguette and gruyere right before serving so it stays crisp.

You will want to serve French Onion Pot Roast over Mashed Potatoes to soak up the beefy broth, along with some Dinner Rolls on the side so you don’t miss a drop. For a simple and French-inspired full course holiday meal, try French Bread Rolls, Green Bean Almondine, and Spinach Gratin.

  • Onions: Try white onions for a more traditional French Onion soup or use Vidalia Onions for a less potent, slightly sweet onion flavor. For a spicier, sharper onion flavor, use a mixture of half red onions and half yellow onions. 
  • Veggies: Turn this soup into a stew by adding large chunks of carrots, sweet potatoes, or red potatoes to the broth before placing in the oven. You can also stir in kale, broccoli, cabbage, or spinach during the last 30 minutes of cooking.
  • Cheese: Use other fancy, but easier to find, cheese that melt easily like Swiss cheese, provolone cheese, Havarti cheese, or Muenster cheese to save money and still get flavor!
  • Wine: Add up to 1 cup dry red wine, dry white wine, sherry, or brandy with the broth to add more traditional French flavors. For red wine, try a Pinot Noir or Merlot. For white wine, use Sauvignon Blanc or Pinot Gris.

Slow Cooker French Onion Pot Roast

  • Season the roast with salt, pepper, and thyme. Rest while you gather the rest of your ingredients.
  • In a large skillet over medium heat, heat the oil until shimmering. Add the beef and brown deeply 3-4 minutes each side.
  • Place roast and remaining ingredients, except baguette slices and cheese, in the slow cooker.
  • Cover with lid and cook for 7-8 hours on low, or on high heat for 3-4 hours, until meat is fork tender.
  • Turn oven to broil. Arrange baguette slices on a baking sheet and top with cheese. 
  • Broil bread until edges are browned and cheese is melted.
  • Serve French Onion Pot Roast with cheesy baguette toasts.

Instant Pot French Onion Pot Roast

  • Season beef on both sides and allow to rest at room temperature.
  • Heat oil in Instant Pot on Saute Function. Once oil is hot, add beef and brown on both sides for 3-4 minutes each.
  • Remove roast and set aside. Deglaze Instant Pot with 1 cup broth, scraping off any brown bits.
  • Return beef to pot and add the remaining ingredients, except bread and cheese.
  • Close and secure lid and seal pressure valve. Cook on Manual High Pressure for 15 minutes per pound (45-60 minutes).

  • While pressure is releasing, broil cheese on baguette slices until browned and bubbly.
  • Serve pot roast topped with toasted cheesy baguette slices.



  • Serve: French Onion Pot Roast is best served as soon as you toast the bread so it doesn’t get soggy. You can keep this pot roast at room temperature for up to 2 hours.
  • Store: Store the cheese toast and French Onion Pot Roast separately. Keep the pot roast in an airtight container in the refrigerator for up to 3 days. The cheese toast is good for about 2 days in a plastic storage bag in the refrigerator.

  1. Loved the roast! The cheese was definitely NOT my favorite so we will be making this again and leaving the cheese out. The roast came out super tender.

  2. Super easy and incredibly delicious. I did deglaze the Dutch oven with red wine before adding the onions and broth. The cheese toast was amazing too. Try this one!

  3. Wow! Dare I say the leftovers the next day we’re even better. Make sure to get good cheese because it really makes this dish.

  4. Delicious!!! Everyone RAVED about the fabulous taste! Just like French Onion Soup with meat. The flavor only increases day by day! Couldn’t find the thyme sprigs at the store, so just added 1/2 teaspoon dried thyme to the salt and pepper, and rubbed it into the meat.
