Steakhouse Sandwich

We are true carnivores and love a good steak sandwich. When it comes to steak sandwiches, I think it’s all about the marinade used for the steak as well as the sauce put on the bread. In this recipe for a Steakhouse Sandwich, I am giving you both a marinade and a sauce that will definitely check both boxes!

Marinating steak is really important when you plan to use it on a sandwich. You want the meat to be extra tender so that when you bite into it you don’t just pull the whole piece of steak. I usually try to get the steak marinating the night before, but you can also do it in the morning before work or even on your lunch break. The longer you have for the meat to absorb the flavor as well as the oil, the better.

The horseradish mayo is what makes this steak sandwich a Steakhouse sandwich. If you haven’t had the pleasure of having a creamy horseradish with your steak, you are missing out. While horseradish does pack a heat punch, when you mix it with the mayonnaise and fresh chive, you get a cooling effect that just highlights the flavor. If you cannot stand the spice level of using horseradish, you can sub it out for a spicy mustard or a dijon mustard. If you have powdered horseradish, you can substitute that, however I am not sure what the proper ratio would be, so be sure to check that with the product maker.

I like to use a really hefty hearty bread for a sandwich like this. My grocery bakery has these “bake-at-home” multi-grain loaves. I can get two sandwiches out of each of them. Since they have to be baked, I get a nice warm bread for the sandwiches. You want something with a nice crusty outside but soft and chewy on the inside. For some sandwiches, the bread is just an edible napkin, but for others it’s an integral part of the whole experience.

As with any entree sandwich – a potato side is usually a great idea. My family loves the Salt & Pepper Crinkle Cut by Kettle to go with sandwiches like this. You can also do any cut of french fry, or tater tots. Since you have the spinach on the top, a side salad may be too much ruffage, but you could certainly do a small green salad.
