Lomo saltado is Peruvian dish that combines beef stir-fry, french fries and rice. Make this paleo/whole30 version in your slow cooker or Instant Pot.
I had lomo saltado for the 1st time a few months ago and it’s been on my radar ever since. Succulent beef, french fries, delicious sauce…what’s not to like? There are tons of different versions of lomo saltado out there. What I love about this recipe is that you can put your own unique spin on it. While usually made as a stir-fry, my version is made here in the Instant Pot with instructions for slow cooker as well. Like a lot of my recipes, it’s all about the sauce. The sauce is a simple combination of coconut aminos (or low-sodium soy sauce but not compliant), vinegar and beef broth.
Aji Amarillo Paste
Aji amarillo paste is a popular ingredient in Peruvian cooking made from the aji amarillo pepper. Aji amarillo literally means “yellow chili” in Spanish which makes sense because the pepper is golden in color. It also packs heat; aji amarillo is a spicy pepper hence why only a little is used here.
You can find aji amarillo paste in specialty grocery stores and online. I was able to find it very easily and inexpensive so I used it in my recipe but I understand that might not necessarily be the case for most people. This recipe went through several rounds of recipe testing (more than I would have liked to be honest) and in round #2 I specifically used a generic habanero sauce as a aji amarillo paste substitute and guess what? It worked just fine with very minimal difference in taste.
Potatoes AND Rice
Traditionally, lomo saltado is serves with two starches – both french fries and rice. To make this version paleo and whole30 compliant, I made my own homemade air fryer french fries using potatoes (or you can use sweet potatoes) and I substituted the rice for cauliflower rice. Because of the potatoes, this recipe is not low-carb. Of course you can omit them but the fries are a big part of lomo saltado. Having said that, if you do omit the fries, you’ll still have nice ‘beef, onion, and tomatoes in Peruvian sauce over cauliflower rice’ to enjoy. If you’re not worried about this recipe being paleo or whole30, you can serve this with regular white rice instead of cauliflower rice.
I followed my air fryer fries recipe to a tee when making this recipe. If you do not have an air fryer, you can pan-fry the fries or bake them. Below are methods for both. Regardless of your method for making the french fries, I suggest you soak the cut up potatoes in water for 30 minutes prior to remove excess starch.
Pan-Fried French Fries – Place the fries in a single layer in a large skillet at least 1-inch deep (like a cast iron skillet). Add 1 cup of compliant oil of your choice (doesn’t matter to me what you use) at turn on the heat to medium. Cook potatoes 15-20 minutes, stirring occasionally. When they’re done to your liking, remove the fries and place them on a paper towel to absorb excess oil. Toss with salt and pepper.
Baked French Fries – Preheat oven to 450 degrees. Coat potatoes with 1 tbsp of oil and salt & pepper to taste. Place fries in a single layer on a baking sheet. Bake for 45 minutes in preheated oven or until crisp to your liking.
Slow Cooker Notes
While the pics you see here are from when I made this in my Instant Pot, I have made this in my slow cooker as well. There are a few things to make note of: 1) I did not brown my meat before adding it to the slow cooker. You can if you want to but I did not. 2) This isn’t a recipe that will take a long time to cook. We’re not cooking a roast here. Since the meat is sliced thin, it cooks fairly fast. Mine was done in 1.5 hours on the high setting. 3) You can use less beef broth when slow cooking. A cup of liquid is needed to pressurize the Instant Pot. All that liquid is not needed for the slow cooker. There’s nowhere for the liquid to evaporate when slow cooking so using too much can cause your dish to result in a soupy mess. I lower the broth amount to 3-4 tbsp when using the slow cooker.
