Steak Bites with Onions and Mushrooms

Delicious and juicy seared steak, meaty mushrooms and sweet onions, that is what this dish delivers every time! My family craves this recipe when we are camping, it’s quick to make which means I don’t have hangry campers asking when is dinner and you won’t either.

You can choose any cut of beef that you like, for the recipe I choose strip steak, my grocery store had a special on it. But from time to time I used, Ribeye, top sirloin, and NY Strip successfully.

Cut the steak into 1.5 inch pieces.  If they are any smaller the steak will cook too fast, if they are larger than 1.5 inches the cook time will be longer. Bite size is the way to go for a faster cook time.

Slice the mushrooms all the same size, again by doing this they will not only cook evenly but they will develop a beautiful deep brown color from the hot pan.

Wait to prep the onion until the day you are making this dish. As you know onions have a very strong smell and your RV, ice chest, or home fridge will be perfumed with their strong scent. Best to hold off.

Allow your cast iron pan enough time to pre heat before you start cooking. This can take about 10 minutes, the perfect amount of time for yo to gather all your ingredients you have prepped ahead of time.

Next, we need to assemble the marinade.  Good news you can make this well in advance! I have made and stored this flavorful marinade three days before I used it, another time saver when you are camping.
