Ingredients needed to make an Easy Grilled Steak Tostada

- Steak: Flank steak works great because it cooks quickly and stays flavorful; skirt or sirloin are good alternatives.
- Guacamole: Use fresh store-bought guacamole for convenience, or make your own for a brighter flavor.
- Tostada shells: Store-bought tostada shells keep things easy; you can also crisp corn tortillas in the oven or on the grill.
- Tomato: Fresh tomatoes provide acidity and texture for pico de gallo.
- Onion: White onion adds a sharp, crunchy bite to the pico.
- Jalapeño: Fresh jalapeño gives heat — remove seeds if you prefer milder salsa.
- Lime: Fresh lime juice brightens the pico and balances the richness of the steak and guacamole.
- Cotija cheese: Crumbly cotija adds a salty finish; queso fresco is an acceptable substitute.
How to make a Homemade Pico de Gallo

Homemade pico de gallo is a crisp, fresh topping that complements the smoky steak. To prepare it:
- Core and seed the tomatoes, then dice them into small pieces.
- Finely dice half a white onion and 2 jalapeños (adjust quantity and leave seeds out if you want less heat).
- Chop a handful of fresh cilantro.
- Combine tomatoes, onion, jalapeño and cilantro in a bowl, then season with salt and the juice of one lime.
- Taste and adjust salt or lime as needed before serving.
Recipe Tip
To control heat, remove the seeds and membranes from the jalapeños before dicing. For the best texture, keep pico refrigerated until ready to serve and assemble tostadas just before eating.

Seasonings to Keep On Hand
Having a favorite taco or grilling seasoning makes prep faster and consistent. Use what you enjoy to build bold flavors quickly.
How to grill Flank Steak

This method works whether you use a griddle, cast-iron pan, or a charcoal or gas grill. For quicker serving, cut the flank steak into roughly 1-inch slices, then into bite-sized cubes while still raw. Toss the pieces with a tablespoon of olive oil and about 2 tablespoons of your preferred taco or grill seasoning so they’re evenly coated.
Preheat the grill or griddle to medium-high. Arrange the steak cubes in a single layer and let them sear without moving for 1–2 minutes, then turn and continue cooking, turning every 1–2 minutes until done to your liking. Total cook time for bite-sized pieces is about 5–7 minutes, depending on heat and desired doneness. Remove from heat and let rest briefly before assembling.
Assemble the Easy Grilled Steak Tostada
Assembling is quick and flexible. Follow these steps for a balanced tostada:
- Spread a generous layer of guacamole on each tostada shell to create a creamy base and help prevent sogginess.
- Spoon a portion of the grilled steak onto the guacamole.
- Add a heaping spoonful of homemade pico de gallo.
- Finish with a drizzle of Mexican crema or sour cream and a sprinkle of cotija cheese.
- Serve immediately while the shell is still crisp.
Leftovers and Storage
Store leftover steak in an airtight container in the refrigerator for up to four days. Keep pico de gallo, guacamole and crema in separate containers to preserve freshness. Tostada shells should be kept at room temperature in their original packaging or a sealed container to maintain crunch. Assemble just before serving for the best texture.
Final Thoughts

These Easy Grilled Steak Tostadas combine crisp, fresh and smoky elements for a memorable, fuss-free meal. The bright pico and creamy guacamole temper the richness of the steak, while cotija cheese adds a salty finish. Whether you’re cooking fresh steak or using leftovers, this recipe makes a flavorful, quick dinner that’s likely to become a regular in your rotation.
Frequently Asked Questions:
Flank and skirt steaks are popular choices because they grill quickly and slice nicely. Sirloin, ribeye, or New York strip also work if you prefer a different texture or flavor.
Yes — leftover steak is an excellent shortcut. Reheat gently and add to tostadas just before serving so the shells stay crisp.
Assemble tostadas right before serving. Keep toppings in separate bowls so guests can build their own, and spread guacamole directly on the shell to create a moisture barrier.
