How to make a Steak Sandwich with Caramelized Onion

One of my favorites, join me for this delicious recipe if you don’t like caramelized onion – that is not an issue ignore the onion preparation part and focus only on steak sandwich which is fantastic on its own. Make sure you select a good piece of steak to enjoy your sandwich, the better the steak the more you will enjoy your sandwich!


  • Medium beef steaks (2)
  • One yellow onion (sliced)
  • Ciabatta Bun (2)
  • Balsamic Vinegar (2 tbsp)
  • Garlic clove (2)
  • Mayonnaise (4 tbsp)
  • Sugar (1 tsp)
  • Olive oil
  • Salt and Pepper


  1. Large mixing bowl
  2. Garlic press
  3. Large non-stick pan
  4. Measuring Spoons
  5. Grill pan


1.Caramelize Onions 

Heat a large non-stick pan over medium heat. Add 1 tbsp olive oil and onions. Cook, stirring occasionally until softened, about 4 min. Add 1tsp sugar and season with salt to taste. Continue to cook stirring occasionally, until onions are golden-brown, about 10 min. When onions are done, remove the pan from heat. Add 2 tbsp balsamic vinegar. Stir together 1 min. Transfer caramelized onions into a small bowl and set aside.

2. Cook the Steak

Same as for the previous steap start by heating a large non-stick pan over medium-high heat. You can use the same pan just wipe carefully with a paper tower. When the pan is hot, add 1tbsp olive oil, then steak and 1 fresh garlic clove cut in half. You can also add rosemary for more flavor. Cook the steak for about 5 minutes per side, turning it every 1 min. When steak is done, remove and transfer to a wooden cut board, let rest for 3-4 min.

3. Prepare the dressing  

Meanwhile, peel, then mince 1 garlic clove. In a small bowl stir together minced garlic and 4 tbsp mayonnaise. Save for later.

4. Toast Ciabatta

Halve ciabatta buns. Grill on one side using a grill pan over medium heat. Toast until golden-brown, about 3 minutes.

5. Finish and Serve

Thinly slice steak. Spread garlic and mayonnaise dressing over ciabatta halves, then top with steak and caramelized onions. Enjoy! Don’t forget to add a side to your sandwich, a healthy salad would do the deal, I would recommend Caprese Salad or Greek Salad.
