This Peruvian beef stir fry (also know as Lomo Saltado), is one of my new favorite steak dishes.  Traditionally, a combination of steak, onions, tomatoes, and French fries, this dish is full of flavor, savoriness and pure deliciousness.  Not only is it fast and easy to make but it takes the steak and potato meaning to a whole other level!

Step 1: Season and sear the beef

The Peruvian Beef stir fry or Lomo Saltado is made in a cast iron therefore choose a cut of beef that is lean with little marbling.  I went with 3 beautiful filet mignon’s. 

Seasoned filet mignon

Season all sides with Dad’s Steak seasoning.  Preheat the grill to a high heat over direct heat.  Place the steak’s on the grates and only sear them off.  Cook about 1 minute per side or until all sides are nicely browned up.  Yes the steak will be raw on the inside, but we will cook it down further once in the skillet later in the recipe.

Remove the steaks off the grill and let the meat rest.

Cook a handful of steak cut fries in the airfryer or oven.  Allow them to get brown and crispy without burning them.  This will help create a strong barrier and prevent them from getting soggy.

Recipe Tip

  • Use a filet mignon.  It’s the most tender cut of beef.

Dad’s Seasonings

Must have grillin seasonings!

Step 2: Sauté veggies

Sautéed veggies over grill

For this recipe all you need is a red onion, roma tomatoes and some fresh garlic. Slice the onion into thicker slices.  Repeat the same on the tomatoes and also remove the inside and seeds.

Place a cast iron skillet on the grates and add some olive oil.  Toss the sliced veggies in the skillet and let them sauté over the direct fire.  Season the veggies with more of Dad’s Steak seasoning for additional flavor.  Once the onion and tomatoes are soft, throw in the sliced garlic cloves and continue sautéing. 

For the sauce, in a mixing bowl add equal parts soy sauce and apple cider vinegar, sriracha or hot sauce of your choice and corn starch. Whisk the ingredients together and pour it over the sautéed veggies.

Recipe Tip

  • Remove the inside including the seeds from the tomato to avoid a watery dish.
  • Use large crispy fries to avoid sogginess when mixed in with the cooked ingredients.

Step 3: Final cook

Peruvian Stir Fry

While the veggies are being sautéed and the steak has rested, it’s time to slice it up and throw it back on the grill.

When slicing any but of beef, always cut across the grain.  This helps keep each bite tender.  Don’t be alarmed if the inside is still raw.  It’s supposed to be.  Cut thin, 1/2 inch slices of steak and then halve those.  Throw them into the cast iron and mix it in with the veggies and sauce.  

Remove it from the grill and add in the crispy fries.  Fold them into the rest of the dish and enjoy this delicious Peruvian Beef Stir Fry.

Frequently Asked Questions:

Can I make this in the oven or stove top?

All my recipes can be replicated in the oven, stove top or gas grill. You do not need a big green egg or weber grill to replicate any of my recipes.

What cut of steak should I use?

Type of steak depends on what you are trying to grill up. For hot and fast look for cuts with good marbling like a ribeye or NY strip. If you are cooking a roast or stew, look for cuts that are cheaper and meatier like a chuck roast.
