Ingredients

For the Shrimp:

• 1 lb large shrimp, peeled and deveined
• 2 tablespoons olive oil
• 1 teaspoon chili powder
• 1 teaspoon cumin
• ½ teaspoon smoked paprika (trust me on this one)
• ½ teaspoon garlic powder
• Salt and pepper to taste
• Juice of 1 lime

For the Creamy Avocado Sauce:

• 2 ripe avocados
• ¼ cup sour cream (or Greek yogurt for a healthier swap)
• Juice of 1 lime
• 2 tablespoons fresh cilantro, chopped
• 1 clove garlic, minced
• Salt to taste
• 2–3 tablespoons water (to thin it out)

For Assembly:

• 8 tostada shells (store-bought or homemade)
• 1 cup shredded cabbage or coleslaw mix
• ½ cup cherry tomatoes, diced
• ¼ cup red onion, thinly sliced
• Fresh cilantro for garnish
• Lime wedges for serving
• Optional: crumbled cotija cheese or feta

Instructions

Step 1: Marinate the Shrimp

In a medium bowl, toss your shrimp with olive oil, chili powder, cumin, smoked paprika, garlic powder, salt, pepper, and lime juice. Let it sit for about 5 minutes while you prep everything else. The flavors will soak right in — don’t skip the lime!

Step 2: Make That Creamy Avocado Sauce

Scoop out your avocados into a blender or food processor. Add sour cream, lime juice, cilantro, garlic, and a pinch of salt. Blend until smooth and dreamy. Add water a tablespoon at a time until you get a drizzle-able consistency. Taste it. Adjust the lime or salt if needed. This sauce is about to be your new obsession.

Step 3: Grill the Shrimp

Heat your grill or grill pan over medium-high heat. Thread the shrimp onto skewers (or just toss them directly on the grill if you’re feeling brave). Grill for 2–3 minutes per side until they’re pink, slightly charred, and cooked through. The smell? Absolutely mouthwatering. Remove and set aside.

Step 4: Prep Your Tostadas

If your tostada shells aren’t crispy enough, pop them in the oven at 350°F for 3–4 minutes. You want that satisfying crunch when you bite in.

Step 5: Assemble Your Tostadas

Now for the fun part! Spread a generous layer of that creamy avocado sauce on each tostada shell. Top with shredded cabbage, a few grilled shrimp (3–4 per tostada), diced tomatoes, red onion, and a sprinkle of fresh cilantro. Drizzle extra avocado sauce on top because why not? Add cheese if you’re feeling fancy.

Step 6: Serve Immediately

Squeeze fresh lime juice over the top and serve right away. These are best enjoyed fresh and crunchy!

Pro Tips & Variations

Make It Spicier: Add diced jalapeños to the avocado sauce or drizzle some hot sauce on top. Heat lovers, this one’s for you.

Swap the Protein: Not a shrimp fan? Use grilled chicken, fish, or even seasoned black beans for a vegetarian twist.

Meal Prep Hack: Grill extra shrimp and store them in the fridge for up to 3 days. The avocado sauce stays fresh for about 2 days if you press plastic wrap directly on the surface to prevent browning.

Bake Instead of Grill: No grill? No problem. Bake the shrimp on a sheet pan at 400°F for 8–10 minutes.

Serving Suggestions

Serve these grilled shrimp tostadas with a side of cilantro lime rice or black beans for a complete meal. They also pair beautifully with a cold beer, margarita, or sparkling lime agua fresca.
