Step‑by‑Step Instructions for Mexican Tostadas de Carne Asada
Step 1: Prepare the Steak Marinade
In a medium bowl, whisk together ¼ cup olive oil, ¼ cup lime juice, 3 cloves minced garlic, 1 teaspoon cumin, 1 teaspoon chili powder, and salt and pepper to taste. Place the flank steak in the marinade, ensuring it's well coated. Cover the bowl with plastic wrap and allow the steak to marinate for at least 30 minutes, or refrigerate it for up to 2 hours for maximum flavor.
Step 2: Cook the Steak
Preheat your grill or a skillet over medium-high heat. Remove the marinated flank steak from the bowl, letting any excess marinade drip off. Cook the steak for 4-6 minutes on each side, or until it reaches your desired level of doneness (look for a nice char). Once cooked, transfer the steak to a cutting board and let it rest for a few minutes before slicing thinly against the grain.
Step 3: Prepare the Fresh Salsa
While the steak is resting, in a separate bowl, combine diced tomatoes, diced red onion, diced jalapeño, a squeeze of fresh lime juice, and salt to taste. Mix everything well until combined. This fresh salsa will add a vibrant contrast to your Mexican Tostadas de Carne Asada, bringing it all together with its bright flavors.
Step 4: Assemble the Tostadas
On a serving platter, arrange the tostada shells. Start by layering the sliced carne asada evenly over each tostada, ensuring every bite has a hearty portion. Next, top each tostada with shredded lettuce, a few slices of avocado, and a generous spoonful of the fresh salsa for a beautiful, colorful presentation.
Step 5: Garnish and Serve
Finish off your Mexican Tostadas de Carne Asada by sprinkling fresh cilantro over the top for an aromatic touch. Serve lime wedges on the side, allowing everyone to squeeze fresh juice over their tostadas for an extra burst of flavor. Enjoy your homemade feast immediately for the best taste and crunch!
How to Store and Freeze Mexican Tostadas de Carne Asada
Room Temperature: Store leftover tostadas at room temperature for up to 2 hours. After that, refrigerate to maintain freshness and avoid spoilage.
Fridge: Place assembled tostadas in an airtight container and store for up to 3 days. It’s best to keep toppings separate to preserve the crispiness of the tostada shells.
Freezer: For longer storage, you can freeze the marinated flank steak for up to 3 months. Thaw in the fridge before cooking. Avoid freezing assembled tostadas, as they won’t retain their crunchy texture.
Reheating: Reheat leftover steak in a skillet over medium heat until warmed through. Reassemble tostadas right before serving to ensure they are fresh and crunchy.
Expert Tips for Mexican Tostadas de Carne Asada
• Marinating Time Matters: Allow the flank steak to marinate for at least 30 minutes, but up to 2 hours gives a stronger flavor punch that enhances your Mexican Tostadas de Carne Asada.
• Don’t Overcook: Keep a close eye on the steak while grilling. Overcooking can lead to tough meat; aim for medium-rare to preserve tenderness and juices.
• Layer Wisely: Start with meat and then balance crunchy textures with avocado and lettuce. This layering technique keeps your tostadas from becoming soggy.
• Customize the Heat: Adjust the amount of jalapeño in your salsa to control spiciness. Test a small piece beforehand to ensure it matches your desired heat level.
• Prep Ahead: For an easy dinner, prep the steak and salsa in advance. Just assemble the tostadas right before serving for a fresh experience!

Mexican Tostadas de Carne Asada Recipe FAQs
How can I select the perfect flank steak?
Absolutely! Look for flank steak that is bright red with minimal dark spots. The meat should be firm to the touch and have a bit of marbling for added flavor and tenderness. Avoid any cuts with excessive graying or a dry appearance.
What’s the best way to store leftovers?
You can store assembled tostadas in an airtight container in the refrigerator for up to 3 days. However, for the best texture, keep the toppings separate until you’re ready to serve again to maintain the crunch of the tostada shells.
Can I freeze the carne asada?
Yes, you can! To freeze the marinated flank steak, place it in a sturdy freezer bag, squeezing out as much air as possible. It can be frozen for up to 3 months. When you’re ready to use it, simply transfer it to the fridge the night before to thaw overnight.
What if my tostadas become soggy?
Very! If your tostadas are soggy, it’s likely due to wet toppings. To avoid this, add toppings just before serving. If they’re already soggy, you can toast them lightly in a preheated oven for a few minutes to restore some crunch.
Are there any dietary considerations with this recipe?
Yes! For those with gluten sensitivities, ensure your tostada shells are gluten-free. Additionally, adjust the amount of jalapeño based on your heat tolerance, and always ask guests about potential allergies to common ingredients like cilantro or avocado to keep everyone safe and happy.
How can I enhance the flavor of my carne asada?
For an extra flavor boost, consider adding additional spices to your marinade, such as smoked paprika or a splash of orange juice. Letting the steak marinate for 2 hours rather than 30 minutes intensifies the flavor even more!
