Ingredients
- Fresh shrimp: Brings protein and a briny sweetness. Pick medium to large shrimp that are peeled and deveined for easy prep.
- Olive oil: Helps the spices cling and boosts browning. Go for extra virgin for fresh flavor.
- Chili powder: Provides the signature warmth. Look for a deep red blend with a hint of smokiness.
- Ground cumin: Infuses earthy notes that complement the shrimp.
- Garlic powder: Adds mellow savor without overpowering, but feel free to use fresh minced garlic for extra bite.
- Tostada shells: Create crisp structure. Choose ones with a deep golden color and no off smells.
- Avocados: Give the spread its luscious creamy base. Pick avocados that yield slightly to gentle pressure but are not mushy.
- Lime juice: Brightens the whole dish. Use freshly squeezed for the purest flavor.
- Fresh cilantro: Adds brightness and herby lift. Rinse and chop just before using for best results.
- Jalapeño: Brings optional heat. For mild flavor remove seeds and white ribs or skip for sensitive palates.
- Fine sea salt and freshly cracked black pepper: Tie it all together. Taste avocado mixture and adjust as needed.
Step-by-Step Instructions
- Marinate the Shrimp:
- In a large bowl combine the peeled shrimp with olive oil, chili powder, cumin, garlic powder, salt, and pepper. Toss well by hand or spatula to evenly coat every shrimp in the spices. Let this sit while you prep the avocado so the flavors can infuse.
- Grill the Shrimp:
- Heat a skillet or grill pan on medium until hot but not smoking. Lay the shrimp out in a single layer and cook for about two to three minutes per side. Use tongs to flip each shrimp once halfway through. When the shrimp turns pink and opaque on both sides, remove from the pan immediately to avoid overcooking.
- Make the Creamy Avocado Base:
- In a separate bowl, scoop out the ripe avocados and mash them with a fork until mostly smooth. Add the lime juice, fresh cilantro, jalapeño (if using), and a pinch of salt. Mix until creamy but still a little chunky for texture. Taste and adjust seasoning.
- Assemble the Tostadas:
- Lay out the tostada shells on a plate or board. Spread each one with a thick layer of the avocado mixture, making sure to cover edge to edge for a sturdy base.
- Add the Shrimp and Finish:
- Top each tostada with a generous pile of grilled shrimp. Scatter extra chopped cilantro on top and serve at once with wedges of lime and any other toppings you love.

I never get tired of the avocado in this dish It is creamy enough to feel indulgent but still light and brings everything together My younger brother always asks for a double avocado layer and it is the ultimate treat when we gather for summer dinners
