Recipe Ingredients
There are four different components to this complex, but easy-to-make Chimichurri Steak Sandwich. To prepare the steak, you need 2-3 filets. I like to go with filet mignon because they provide maximum tenderness and flavor, and coat it in my Bourbon Prime Rub and canola oil.
All you need to create my favorite homemade chimichurri recipe is parsley, 3 cloves garlic, Extra-Virgin Olive Oil, Red Wine Vinegar, Red Pepper Flakes, pepper, and a pinch of salt.
I also top the steak with fried white onions coated in Kosher Salt, Garlic Powder, and Black Pepper fried in frying oil.
Finish off the sandwich with toasted ciabatta bread, provolone cheese, and horseradish aioli. If that sounds as delicious to you as it does to me, let’s get started!
How to Make Chimichurri Steak Sandwich
Begin by thinly chopping your white onions. Add them to a paper towel and squeeze out all the excess water. Set to the side to dry out. This is an important step as the water in the onion will cause popping in the oil when we go to fry them. So make sure you don’t skip this step.
Next, add all the ingredients for your chimichurri to a mixing bowl and stir. Set to the side until ready to use. This is something you could prep the night before if you know you’re looking to shorten the cook time of this Chimichurri Steak Sandwich.
Finally, season steaks with oil and generously lather with my Bourbon Prime Seasoning or your favorite steak rub. Set in the fridge until ready to cook.
Preheat a fire for medium-high heat (about 375F). Add a dutch oven or a deep skillet to the fire to preheat.
Add enough oil to the skillet to be 1” high and heat up till 350F. Carefully add your sliced onions to the oil to fry for only 2-3 minutes until golden brown. Do this in batches so as not to overcrowd the skillet. Finally, pull the fried onions out and pat dry. Season with salt, pepper and garlic. Keep warm until serving.

Grilling Steaks for our Steak Sandwich
Next, add your filets to the grill and grill steak for 3-4 minutes per side or until they are 120F internal. Once the steaks are done, place steaks on a room temperature surface and let rest for 10 minutes. Finally, slice your ciabatta bread in half and toast it up over the fire.
Once rested, slice up your filets. Next, begin building your Chimichurri Steak Sandwich with the toasted bread slathered with your favorite aioli, sliced steak, and fried onions.
Next, top with melted cheese and then the chimichurri.
Finish off with more aioli on the top bun, and close sandwich. Serve and enjoy!

What’s your recipe for your horseradish airline? I’ve seen several different ways to make it. Thanks in advance.
I have an aioli recipe as part of my Leaning Salmon with Roasted Garlic Aioli recipe (https://overthefirecooking.com/leaning-salmon-with-roasted-garlic-aioli/). You could edit that recipe a bit for horseradish. Maybe add a little less garlic and then add in horseradish.
