Lomo saltado is a Peruvian beef stir fry that combines Latin and Chinese elements for one delicious dinner! This lightened up version is packed with flavor, with tender sirloin and veggies served alongside crispy baked fries.

Lomo Saltado is one of Peru’s most beloved dishes. It’s a quick stir-fry of tender sirloin, juicy tomatoes, red onion, and a savory soy sauce, all tossed with golden fries. It might sound like an unexpected combo, but it absolutely works. My lighter take skips the deep fryer and uses baked fries instead, keeping all the flavor with less fat. In Peru, they also serve this stir fry dish with rice, but I personally find it filling with just the potatoes and a slice of avocado on the side.
What You’ll Need
Below you’ll find the ingredients for my lightened up lomo saltado. Scroll down to the recipe card below for exact measurements.
For the Baked Fries:
- Canola cooking spray – Or your preferred cooking spray.
- Potato – I use russet or Yukon gold.
- Olive oil – This is what crisps up the fries.
- Seasonings – Garlic powder, kosher salt and black pepper.
For the Beef:
- Lean sirloin – Cut this into thin strips.
- Seasonings – Kosher salt, cumin, and black pepper.
- Olive oil – For cooking the stir fry.
- Red onion – Slice the onion into thick strips.
- Yellow bell pepper and jalapeño – In Peru they use a yellow pepper called aji amarillo, but it’s not commonly found here in the states. So I subbed it with a jalapeño and added mini yellow peppers in their place.
- Garlic – Fresh garlic adds lots of flavor.
- Tomato – Slice this into wedges.
- Low-sodium soy sauce – Use tamari for gluten-free and coconut aminos for whole30.
- Apple cider vinegar – This adds a nice pop of bright flavor.
- Cilantro – For garnish. If you don’t like cilantro, you can leave it out or swap in parsley.
How to Make Lomo Saltado
While the fries cook, get all the ingredients ready for the stir fry. Stir-fries move fast, so it’s important to start with everything ready! See the recipe card below for printable instructions.
- Prepare. Preheat your oven to 400°F and lightly coat a baking sheet with cooking spray.
- Season the potatoes. Cut the potato into fries, toss the fries with the oil, and add the seasonings. Spread into an even layer on a baking sheet.
- Bake. Place the baking sheet in the oven and bake for about 25 minutes, until the fries are crisp and golden.
- Season the meat. Toss the meat with salt, pepper, and cumin.
- Make the stir fry. Add the oil to a hot wok over high heat. Cook the steak for 2 minutes, until browned, then add the onions, bell pepper, jalapeño, and garlic. Cook for 2 minutes, then add the tomato, soy sauce, and vinegar and cook 1 minute more. Season with salt to taste and garnish with cilantro.
- Serve. Plate the lomo saltado with the fries and serve.
Tips & Variations
- Make sure the veggies and fries are uniform in size. If you have some pieces that are thicker and some that are thinner, they won’t all finish cooking at the same time.
- Don’t overcook the veggies. The vegetables in lomo saltado should be tender-crisp to provide a nice contrast to the beef. Cook them quickly at high heat for the best results.
- Try aji amarillo paste. If you’re able to find aji amarillo paste at your local grocery store or online, you can use a small amount in place of the jalapeño for a more authentic flavor.
How to Store & Reheat
- Refrigerator: Store leftover lomo saltado in an airtight container, with the stir fry on one side and the fries on the other. (Or just use two containers and put the fries in one and the stir fry in another.) Refrigerate for up to 3 days.
- Freezer: Although I think this is best eaten the day you make it, you can freeze this dish by storing it in an airtight container or freezer-safe bag. It will keep for up to 3 months. Thaw in the fridge before reheating.
- To reheat: Heat leftover lomo saltado stir fry in a pan over medium heat until warmed through and warm up the fries in a 400ºF oven. You can also reheat this dish in the microwave, but the fries won’t be as crispy.
