Step 1. Cook the steak

Once the grill is hot place the steaks onto the grill, cook for a few minutes on high to sear in the flavor. Reduce the heat to medium heat, flip over, and add the vegetables. Continue to cook until the steak is done to your preference.

Step 2. Slice the ingredients

Let the steaks rest for about 5 to 10 minutes. Use a sharp knife to slice the steak and peppers.

Ingredient notes and substitutions

Filet Mignon – Beef filet is a highly flavorful meat. Look for a steak that is bright red in color and appears to be well-trimmed with modest marbling.

Salt and Pepper – Tender filet mignon is a cut of meat that doesn’t really need seasoning. However, I prefer to sprinkle some sea or kosher salt and crushed black peppercorns 15 to 30 minutes before cooking. This step is not mandatory, and you can use your preferred beef seasoning or skip it altogether.

Bell peppers – Any color of bell pepper will work.

How to store leftover beef filet sandwiches

Beef filet sandwiches are best when eaten just after cooking them. But in the event you do have leftovers, store the beef, and peppers in the refrigerator for up to 3 days and the rolls separately at room temperature.

Serving Suggestions

Serve these tasty sandwiches with a garden salad, potato salad or coleslaw or serve them as mini filet steak sandwiches on a charcuterie board.

Recipe Variations

Add Veggies such as lettuce or peppery arugula, sliced tomatoes, slices of large fresh California avocado and thin slices of raw onions in addition to the peppers or in place of them.

Change up the cheese and try cheddar cheese, mozzarella, provolone cheese, gruyere cheese or blue cheese.

Lower carb – if you are counting carbs, make this sandwich on open face on a slice of crusty toasted artisinal bread.

Use a different cut of beef –  London broil is a great choice for a crowd, as is flank or skirt steak.

Caramelized onions – instead of grilling onions, make caramelized onions.

Try a vegan version like this Portobello Mushroom Cheesesteak

💡Tips

  • Beef cooks best when it is at room temperature. Allow the steak to reach room temperature by removing it from the fridge for about 30 minutes before grilling.
  • Sear in the juices. Before adding the food to the grill make sure the grill is extremely hot and brush olive oil onto the grates just before adding the food.
  • Cut the peppers into halves or quarters. This will keep them from falling through the grill grates or use a grill topper for the peppers.
  • Slice onions at least a half inch thick in size. This will keep the onion slices from falling through the grates. Use a skewer to hold the layers of the onion together on the grill.
Can I make this sandwich ahead of time and reheat it?

While these sandwiches taste best when they are fresh off the grill, you can assemble them ahead of time and store them in the refrigerator. When serving them, reheat them in a preheated oven at a low temperature (275 to 300 degrees f) until they are warmed through.

Can I make a grilled filet mignon sandwich in a skillet instead of on a grill?

Yes! While grilling adds a smokey flavor, you can easily make this sandwich in a skillet. Season the meat and prepare the ingredients as per the recipe card. Heat a heavy skillet over medium-high heat and add olive oil. Add the filet steak and cook it for a few minutes on each side until it reaches your desired level of doneness. Remove it from the heat and let it rest. Add the peppers and onions and toss them in the skillet until tender. Assemble your sandwich.

  1. I came across this recipe and couldn’t resist to try it, as the name cheesesteak is very attractive, especially for a cheese lover like me. going through this recipe, I found this ingredient ‘The Spice House “Back of the Yards” butchers rub’. I have never heard of it before. Where can I find it? Or what can be its substitute?

    1. Hi Corrie. The Spice house has a website and you can buy it from there or you can substitute with a good quality steak seasoning that’s made with garlic powder, and ground pepper and herbs. It’s very similar to Montreal Steak Seasoning which would work too. I hope this helps! and I apologize for replying so late!
