Notes
How To Make A Delicious Steak and Onion SandwichAre you convinced yet that this gourmet sandwich is really that simple as simple as it sounds?It totally is!A couple of extra tips:Look for the steak when it goes on sale. Make sure you buy the boneless strip steak to save you time and hassle when it comes time to slice the meat for the sandwich.I use a non-stick, non-toxic sauté pans to cook the steak and onions. It’s a set I bought at Costco last year and they are made of Granitium and the brand is Henckels.I only mention this because you may notice it’s different looking coating but you can use any non-stick pan, a ceramic coated cast iron skillet or even aluminum sauté pan.Just be sure to watch the temperature so that you adjust it to prevent burning by cooking it too fast. Different types of materials cook slightly differently.Can this Delicious Steak and Onion Sandwich Be Made ahead? Yes! Well, parts of it anyway.To prep ahead, you can slice the steak before cooking and store in an airtight container in the refrigerator until you are ready to cook it (up to a day ahead is ok).You can also slice the onions the day before and store in the refrigerator as well.Slice your buns the day before then put both halves back together so they don’t dry out and put back in the bag you purchased them in, seal and set aside until ready to prepare the sandwich.These small steps may not seem like much but even just a few minutes here and there can add up.Can You Freeze This Sandwich?Well, yes and no. You wouldn’t want to assemble it then freeze but you can freeze some of the different prepped ingredients. For example, cook the steak and store in an airtight freezer container up to three months or do the same for the onions.When ready to serve, thaw in the refrigerator the day before. Then reheat in the saute pan over medium heat to warm through. You’ll want to watch it so that you don’t over cook the steak and it becomes tough.
