There’s nothing that compares to a great Steak Sandwich! It’s piled high with tender seared strips of skirt steak, caramelized onions, melted provolone, baby greens, and the easiest chipotle mayonnaise on a crusty baguette. It works for lunch, weeknight dinners, gatherings, or tailgates!
A perfectly prepared steak sandwich is truly a thing of beauty.
I’ve tried many steak sandwiches in my life and this method of preparation, and ingredient combination is the one I come back to all the time.
From the caramelized onions, to the tender skirt steak, and the chipotle mayo, the flavors are just stellar.
This steak sandwich is excellent alongside a simple green salad and a pile of French fries.
Recipe Ingredients
All ingredients for this recipe are shown in the pic below and special notes are made in this bulleted list to assist you.
- Steak. My steak of choice for a steak sandwich is skirt steak because it’s super flavorful. You can often find good prices on skirt steak at Costco. You can also use flank steak, or thinner cuts of ribeye.
- Bread. I’m using a baguette for this recipe but you can easily make a steak sandwich with ciabatta rolls.
- Cheese. I’m using sliced provolone. Ask the deli clerk for “sandwich slice” thickness for easy handling. I like the bite of the provolone but you can also use Swiss.
- Chipotle. For the chipotle mayo, canned chipotles, and the adobo sauce they’re canned in will provide maximum flavor.
See the recipe card for full information on ingredients and quantities.
How to make it
- In a small bowl combine one cup of mayonnaise, 1/4 cup of sour cream, and 3 tablespoons of adobo sauce from a can of chipotle peppers. Chop 3 chipotles, add them to the mayonnaise, and mix until combined. Taste test and season with salt and pepper, if needed. Set aside. Note: chipotles can vary from mild to spicy, so it’s a good idea to taste along the way to ensure your mayo is at your preferred spice level.
- Slice 3 large red onions and add them to a large pan or pot along with 1/2 cup of water, 3 tablespoons of olive oil, and 1 teaspoon of Diamon Crystal kosher salt. Turn the heat to high, cover the pan, and cook for 12-15 minutes or until the onions are soft and most of the water has evaporated.
- Uncover the pan and turn the heat down to medium and continue to saute the onions until they’re deeply caramelized, about 30-40 minutes. Be sure to look after the onions as they cook and adjust the heat, or add a splash of water to prevent burning.
- Preheat the oven to 450f and set the rack to the middle level. Heat a large cast iron or stainless steel pan to medium-high heat. Cut 1 1/2 pounds of skirt steak in half or into thirds so it can fit in the pan, then pat dry with paper towels and distribute 2 1/2 teaspoons of Diamond Crystal kosher salt and 1/2 teaspoon of black pepper on both sides of the steak.
- Add 2 tablespoons of a neutral-flavored oil, such as avocado oil, to the pan and once smoking, add the steak.
- Sear the steak for 3 minutes per side or until well-browned.
- Place the cooked steak on a cutting board and allow it to rest, tented with foil, for at least 5 minutes. After 5 minutes, cut the steak into 4-inch pieces, then slice against the grain into 1/4-inch thick slices.
- Slice 1 large baguette lengthwise and separate the two sides. Place the bottom side of the baguette onto a foil-lined baking sheet and spread a layer of the chipotle mayonnaise, followed by the steak.
- Evenly spread the caramelized onions on top of the steak, then add a layer of provolone cheese (about 1/2 pound).
- Place the top side of the baguette onto the backing sheet and with a pastry brush, spread a thin layer of olive oil so it will toast. Place in the oven and bake for about 3-5 minutes or until the cheese has melted. Watch carefully to prevent burning.
- Remove from the oven and spread the chipotle mayo onto the top of the baguette. Distribute 1-2 cups of baby arugula on top, if using.
- Slice the baguette into 4 large sandwiches, serve, and enjoy!
Top tips
- The steak. Be sure to slice the steak against the grain. This makes it so much easier to bite the steak sandwich. A good quality slicing knife makes it so much easier to get thin slices of steak.
- Don’t skip the greens! I listed the baby arugula as optional, but I recommend you use it! It adds great color, texture, and brightness to the steak sandwich. You can also use spring mix or other greens of your choosing.
- Taste test the chipotle mayo. Chipotle peppers can range from 2,500-10,000 on the Scoville Heat Unit scale, which means some can be mild, and some can be spicier side. You really never know the heat level unless you taste for yourself. Be sure to taste test the mayo and use less or more depending on your heat tolerance.

Notes
- For a quicker sandwich, simply saute the onions for 5-10 minutes instead of using the caramelizing process. Or, prepare the onions ahead of time.
- Arugula creates a better appearance but is 100% optional.
- Leftovers can be saved in the fridge for up to 3 days and can be reheated in the oven wrapped in foil at 350f until warm.

We’re so happy you enjoyed, Dylan!
I have done several of your recipes and will definitely be making this coming up! I will use flank steak as the Costco I shop had no skirt steak. Can’t wait, it looks fabulous!
We hope you love it! Thanks for the commment!
Can you use a different type of steak such as sirloin or strip steak????
Hi Peter, you can. In the Ingredient section of the post Jim suggests flank or thinner cuts of ribeye as good alternatives.
Love the sounds of this. I have a freezer full of strip steaks, do you think they would be too lean to get a happy result here? Your thoughts would be appreciated, rather than to proceed and be disappointed! Thanks for your always “right on” recipes and advice.
Hi Den, you can definitely use strip steaks for this. Hope you enjoy!
This is a delicious sandwich and I love your easy to follow instructions.
We’re so happy you enjoyed, Frank!
