Seitan Lomo Saltado Recipe
Introduction
Seitan Lomo Saltado is a vibrant vegan take on the classic Peruvian stir-fry, blending tender strips of seitan with fresh vegetables and tangy sauces. This dish combines bold flavors and satisfying textures, perfect for a quick weeknight meal.

Ingredients
- 2 tbsp. vegetable oil, plus more if needed
- 1 lb. seitan, cut in strips
- 1 medium red onion, sliced
- 2 aji amarillo or fresno chiles, seeded and sliced
- 2 roma tomatoes, cored and sliced
- 3 cloves garlic, minced
- Kosher salt
- Freshly ground black pepper
- 1/4 cup soy sauce
- 3 tbsp. apple cider vinegar
- French fries
- 2 tbsp. cilantro, chopped
Instructions
- Step 1: Heat 2 tablespoons of vegetable oil in a skillet over high heat until it just starts to smoke. Add the seitan strips and sear, stirring occasionally, for 4 to 5 minutes until they begin to caramelize.
- Step 2: If there is no visible oil in the pan, add about a tablespoon more. Then add the sliced red onion and aji amarillo or fresno chiles. Cook, tossing constantly, for 3 minutes until the onions start to soften.
- Step 3: Add the sliced tomatoes and cook for an additional 2 to 3 minutes, tossing with the other ingredients. Ensure the tomatoes retain some bite and haven’t fully cooked down.
- Step 4: Stir in the minced garlic, a good pinch of kosher salt, and a couple of cracks of black pepper. Let cook for another minute to combine the flavors.
- Step 5: Reduce the heat to medium and add the soy sauce and apple cider vinegar. Stir well until the seitan and vegetables are fully coated with the sauce. Let the sauce reduce and thicken slightly for 1 to 1 ½ minutes.
- Step 6: Remove the skillet from heat and fold in the French fries, tossing until they are fully incorporated into the mixture.
- Step 7: Garnish with chopped cilantro and serve immediately for the best texture and flavor.
Tips & Variations
- For a spicier kick, include the seeds from the chiles or add a pinch of cayenne pepper.
- Use sweet potato fries instead of traditional French fries for a slightly sweeter contrast.
- To add extra depth, you can marinate the seitan briefly in soy sauce and garlic before cooking.
- If you can’t find aji amarillo, a mix of yellow bell pepper and serrano chile works as a mild substitute.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat to preserve the texture of the seitan and fries. Avoid microwaving directly to prevent sogginess.

Ingredients
Main Ingredients
- 2 tbsp vegetable oil, plus more if needed
- 1 lb seitan, cut in strips
- 1 medium red onion, sliced
- 2 aji amarillo or fresno chiles, seeded and sliced
- 2 roma tomatoes, cored and sliced
- 3 cloves garlic, minced
- Kosher salt, to taste
- Freshly ground black pepper, to taste
- 1/4 cup soy sauce
- 3 tbsp apple cider vinegar
- French fries, cooked and ready
- 2 tbsp cilantro, chopped
Instructions
- Heat the Oil and Sear Seitan: In a skillet over high heat, heat 2 tablespoons of vegetable oil until it just starts to smoke. Add the seitan strips and sear them, stirring occasionally for 4 to 5 minutes, until they begin to caramelize and develop a golden crust.
- Sauté Onions, Chiles, and Tomatoes: If the pan looks dry, add about a tablespoon more oil before adding sliced red onions and aji amarillo (or fresno) chiles. Cook while tossing constantly for 3 minutes until onions start to soften. Add sliced tomatoes and cook for 2 to 3 additional minutes, stirring gently, until the tomatoes retain some bite and haven’t fully broken down.
- Add Garlic and Seasonings: Stir in the minced garlic along with a good pinch of kosher salt and several cracks of freshly ground black pepper. Let everything cook together for about 1 minute to meld the flavors.
- Add Soy Sauce and Vinegar: Reduce the heat to medium and pour in the soy sauce and apple cider vinegar. Stir well to coat the seitan and vegetables evenly. Allow the sauce to reduce and thicken slightly by cooking for 1 to 1½ minutes, stirring occasionally.
- Toss with French Fries and Finish: Remove the skillet from heat and add the cooked French fries to the pan. Toss gently to incorporate the fries fully with the saucy seitan and vegetables. Finally, sprinkle with chopped fresh cilantro and serve immediately for a delicious, hearty meal.
Notes
- Use firm, prepared seitan to ensure it holds up well during searing and stir-frying.
- Aji amarillo peppers are traditional and add authentic flavor, but fresno chiles are a suitable spicy substitute.
- For best texture, use freshly cooked crispy French fries or reheat leftover fries in an air fryer or oven before adding to the dish.
- Adjust vinegar and soy sauce quantities to taste for acidity and saltiness balance.
- Serve immediately as the fries can become soggy if left to sit.
- Can be paired with steamed rice or served as a stand-alone entree.
