French Onion Soup Burgers

🍔🧅 French Onion Soup Burgers 🍔🧅

I have finally found a burger that I just want to eat all the time. And I’m not normally a big burger person! These French Onion Soup Burgers are everything a burger shoul

They’re juicy and super flavorful and can I just say Caramelized Onions and melty Provolone or Gruyere and an Onion Bun just to drive those flavors home? Do I even need to say anything else?

Prep Time: 20 minutes

Cooking Time: 30 minutes

Total Time: 50 minutes


  1. 1 1/2 pounds ground beef
  2. 1 packet or about 4 to 6 tablespoons Lipton Onion Soup Mix
  3. 2 1/2 tablespoons butter
  4. 2 large onions, thinly sliced
  5. a pinch of thyme
  6. water as needed, about a 3/4 cup
  7. 1 tablespoon brandy or Sherry (optional, but recommended)
  8. 4 to 8 ounces Swiss or Provolone cheese
  9. 4 buns and a little butter or oil to brush them with


  • Mix ground beef with onion soup mix; set aside to rest as the onions are caramelized.
  • Add the butter to a skillet, when hot, add the onions and thyme and about 1/4 cup of water. Add lid and allow to simmer for three or four minutes until onions are tender are the water is nearly evaporated.
  • (Check during cooking time to make sure all the water hasn’t evaporated early.) Remove lid and continue to cook, stirring often and adding a splash of water now and then if the onions are beginning to darken unevenly and stick to the pan. When onions are soft and beautifully browned, add dash of the brandy or Sherry and remove from heat.
  • Place a dent in the top of each burger so they’ll cook up flat and not rounded. Cook on the stovetop in a medium-hot pan or on the grill over medium-high heat, turning once, for about three minutes on the first side. Turn and add a spoonful of caramelized onions and a slice or two of cheese to the top of each burger, lower the heat to medium and continue to cook until burger is desired doneness, two to four minutes longer. Cover if needed, for a minute or two to get the cheese to melt.
  • In the meantime, brush the cut side of the buns with butter or oil and toast in a hot pan or on the grill.

Notes on temperature:

We like ours at 143 degrees F. which is just slightly pink in the middle.

  • rare: 125 degrees (dark purple-red, just warm, tender)
  • medium rare: 135 degrees (bright purple-red, warm, tender, very juicy)
  • medium: 145 degrees (rich pink, yielding, slightly tender, juicy)
  • medium well: 155 degrees (tan with slight pink, firm, some juice)
  • well: 160 (tan to brown, no pink, chewy, little if any juice)

If you need more or less than four burgers, for each burger:

For each burger:

  • 6 ounces ground beef
  • 1 to 1 1/2 tablespoons onion soup mix
  • 2 teaspoons butter
  • 1/2 large onion, thinly sliced
  • a small pinch of thyme
  • water as needed
  • 1/2 teaspoon brandy or Sherry (optional, but recommended)
  • 1 to 2 ounces Gruyere (Swiss) or Provolone cheese (one or two slices)
  • 1 bun and a little butter or oil to brush it with

Air Fryer Method;

  1. Line the air fryer basket with foil or parchment and spray with olive oil spray.
  2. Place the patties evenly in the basket.
  3. Air Fry for 5 minutes at 375 Degrees.
  4. Carefully open and turn and cook an additional 5 minutes at 375 degrees.
  5. Open up the air fryer and see if they are to your desired doneness or at least 165 degrees.
  6. If they need additional time, add an additional 2 minutes to the cook time.
