Pan Seared Onion Burger

Jump to Recipe

One of the juiciest, most flavorful gourmet cheese burger you will ever eat. This is a very quick and simple recipe that can be whipped up for a quick weeknight meal or a gourmet weekend dinner. I used to love (still do) using fresh onions in hamburgers, but years ago on a lazy day, I took the easy way out – that’s where the Lipton onion soup mix came in. A very similar recipe is on the back of the soup mix package. The first time I made the burger patties exactly the way the package suggested and it was good. Subsequent recipes I added fresh garlic and fresh thyme. I have since excluded the garlic as the soup mix is very well seasoned. The thyme add a freshness and now I use less mayonnaise. This current recipe is my favorite by far. The layers of romaine, avocados, eggs and tomatoes added a dramatic flair with a more complex flavor.

  • 2 pounds grass fed ground beef
  • 1 package Liption Onion Soup Mix
  • 1/4 cup mayonnaise
  • 1 tablespoon fresh thyme finely chopped
  • 1 tablespoon extra virgin olive oil
  • 8 slices of cheddar cheese
  • 8 slices of organic vine ripen tomatoes
  • organic romaine lettuce
  • 8 eggs cooked sunnyside or over-easy
  • several slices of avocados (Slice the avocados when you are ready to assemble the burger)
  • 6 to 8 Hamburger Buns


  • 1/2 cup mayonnaise
  • 1 tablespoon freshly squeezed lemon juice
  • 1 garlic clove minced
  • 1 teaspoon cayenne pepper
  • salt and pepper to taste


  1. In a medium bowl, add the ground meat, onion soup mix, mayonnaise and thyme. Mix thoroughly to combine.

    Note: Do not overmix as it will cause the burgers to be tough.

  2. Portion out the seasoned meat into 8 equal portions. In the palm of your hand form a meatball (round) and then create the burger pattie. To do this, place each round in one palm and use the other palm to flatten out to about 1/4 inch thickness. (Alternatively you can place the meatballs on parchment paper and flatten with your palm.) Use your thumb to create a slight indentation in the middle of each pattie. (This will prevent the pattie from puffing up in the middle when it's cooking, hence it will cook evenly).

  3. Heat a large non-stick frying pan over high heat. Add one tablespoon olive oil (Twirl it around to coat the pan).

  4. Depending on how large your pan is, add 3 to 4 burgers at a time and sear each side 3 to 4 minutes – total of 6 to 8 minutes. During the last 2 minutes add a slice of cheese to each burger pattie. Allow the cheese to melt. Remove the burger patties to a plate. Cook the remaining burgers.

    Notes: OPTIONAL: During the last minute after the cheese has been placed on the beef patties, cover the pan with a tight lid to completely melt the cheese.


  1. In a small bowl, add all the alioli ingredients and add salt and pepper to taste. Use a small spatula or spoon to mix thoroughly.

    Notes: This can be made earlier in the day or a day in advance. Refrigerate until ready to use.


  1. Spread some aioli on both halves of the buns. On one half of the hamburger bun, add a piece of lettuce. Add a few slices of avocados. add 1 burger pattie. Add another piece of lettuce. Add egg. Add another burger. Top with 1 or 2 slices of tomatoes. Top with the other half of the bun.

    Plate. Serve. Enjoy.
