I love pairing the shrimp seasoning with a sprinkle of cotija cheese for an extra salty kick. When I first added this, it elevated the tostadas into an irresistible appetizer everyone wanted.
Smart Storage Tips
Store cooked shrimp and avocado topping separately in airtight containers up to 24 hours to keep flavors fresh and textures intact Reheat shrimp briefly on the grill or pan to avoid overcooking before serving again Tostada shells keep best when stored in a sealed bag at room temperature to maintain their crunch
Ingredient Variations
Swap shrimp for grilled fish like mahi-mahi or firm white fish for a different seafood twist Add diced tomatoes or pickled onions on top to introduce extra acidity and crunch Use Greek yogurt mixed with mashed avocado for a tangier creamy layer and added protein
Perfect Pairing Ideas
Serve with a fresh mango salsa for a sweet contrast Offer a chilled Mexican-style beer or a crisp white wine like Sauvignon Blanc to complement the bright flavors A side of black beans and cilantro lime rice makes this a fuller, well-rounded meal
Seasonal Makeovers
In fall swap lime for blood orange juice for a unique citrus flavor Add roasted corn kernels in summer for a naturally sweet, smoky touch In winter, add a dash of smoked paprika to the shrimp seasoning for deeper warmth

Letting these tostadas rest briefly after assembly really brings the flavors together and softens the tostada shell just enough without losing its crunch. This simple dish embodies bright, fresh cooking that satisfies hunger and celebrates flavor in every bite.
