  • Author: Amanda
  • Total Time: 40 minutes
  • Yield: 4 1x


This simple burger recipe is made with only 5 ingredients and topped with French style caramelized onions, peppery arugula, and steamed provolone cheese. All on a brioche or whole wheat bun. YUM



For the burger patties

  • 1lb 85% lean ground beef*
  • 1/4 cup of diced yellow onion
  • 1 tsp salt
  • 1 tsp black pepper
  • 1 tsp garlic powder
  • 1 tsp black garlic (I had some on hand from Trader Joe's and it was YUM in these - but totally optional!)
  • Pinch of red pepper flakes
  • 1 tsp paprika
  • 1 tbs worchestershire sauce

Caramelized Onions

  • 1 large yellow onion, thinly sliced
  • 1 tsp coconut sugar or cane sugar
  • 1 tbs of ghee or grass-fed butter

Burger Add-Ons

  • Arugula
  • Brioche Bun or Lettuce Wrapped
  • Provolone Cheese


  1.  MIX IT -  In a large bowl, combine beef, onion, spices, and worchestershire sauce. 
  2. Form It- Form into 4 evenly sized patties and store in the fridge while you make the caramelized onions. 
  3. SAUTE - Heat a high rimmed skillet over medium high heat. Add ghee. Once it starts simmering, add the onion. Stir frequently to prevent burning. After the onions have softened (about 3-5 minutes), add the sugar. The sugar helps the caramelization process move faster. Keep sauteeing until all onions are a dark brown color. (about an additional 7-10 minutes). Discard to a paper towel lined plate and set aside.
  4. Cook- In the same skillet, add the burger patties. Cook about 2 minutes per side. About 1 minute before the burgers finish cooking, add the cheese (if using). 
  5. Steam the cheese - To get super yummy gooey cheese, put the lid on the skillet for 1 minute. And be prepared to be WOWED by the steamed provolone cheese 🤤
  6. ASSEMBLE - Build your perfect french onion style burger. To the bun add the burger, onions, and arugula. So simple yet so good! 


*Toasting the brioche buns in the oven with a little butter to get them golden brown and a little crispy on the inside is a good idea.

* You can swap the ground beef for whatever ground meat you have. Just make sure it's cooked through all the way!

** For other substitutions, see full details in my post above.
