Cheese Stuffed Onions:

  • 2-3 Whole Yellow Onions
  • 1 cup Swiss Cheese cubed
  • Kosher Salt to taste
  • Olive Oil as needed

Garlic Herb Infused Oil:

  • 1.5 cups Olive Oil
  • 4-5 Garlic Cloves crushed
  • 2-3 Rosemary Sprigs
  • 2-3 Thyme Sprigs


Steak & Oil:

  • Slather your steak with oil and generously season with my Gaucho Steakhouse Rub or your favorite steak rub. Set to the side until ready to cook.
  • Preheat your grill to medium high heat (about 350F) for direct cooking.
  • Add a cast iron skillet with all the ingredients for the garlic infused oil. Once the herbs are simmering, cook over the heat for 10 minutes making sure to stir around occasionally. Once done, pull off and let cool.
  • Add your steaks to the heat and cook for 12-15 minutes or until they are 125F internal.
  • Make sure to baste the outside of the steaks with the infused oil when flipping for added flavor.
  • Once done, pull off and let cool for 10 minutes.
  • Slice up the steak and serve with the Cheese Stuffed Onions.


  • Placing the root of the onion on the cutting board, slice off the top of the other side.
  • Carefully using your knife or a spoon, core out the middle until you are left with a cup shape.
  • Preheat your grill to medium heat (about 300F) for direct cooking.
  • Add your onions with the cup side facing down towards the heat. Let cook for 2-3 minutes until the edges are caramelized.
  • Next, flip the onions over and add a little olive oil into the cup along with the cubed swiss cheese.
  • Let cook for 10 minutes uncovered.
  • Next, cover the onion tops with foil or a fire resistant pan.
  • Add some cooler charcoal (ashy coals) to the top and let cook for another 10 minutes or until the cheese is melted and the onions are soft.
  • When done, pull off and let cool for 2-3 minutes.
  • Slice and serve up with your steak!
