Step‑by‑Step Instructions for Garlic Shrimp Crostini with Avocado
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This will keep the crostini from sticking and ensure even baking. While the oven warms up, prepare your workspace by gathering your ingredients to make the cooking process smoother and enjoyable.
Step 2: Crostini Prep
Slice the baguette into ½-inch thick pieces and arrange them on the prepared baking sheet. Brush each slice generously with extra virgin olive oil mixed with garlic powder, ensuring they are evenly coated. Bake the baguette slices in the oven for 10-15 minutes, or until they turn golden brown and crisp, providing the ideal base for your garlic shrimp crostini.
Step 3: Avocado Mixture
In a mixing bowl, scoop out the ripe avocado and mash it using a fork until smooth. Add in the lime juice, salt, and black pepper, mixing thoroughly to create a creamy, zesty avocado spread. Aim for a vibrant green color without any large lumps; a well-prepared avocado topping will elevate your garlic shrimp crostini’s flavor.
Step 4: Shrimp Cooking
Heat a tablespoon of olive oil in a skillet over low heat. Once the oil is warm, add thinly sliced garlic cloves and sauté for about 2 minutes until fragrant, but be careful not to let them brown. Increase the heat to medium-high, add the shrimp, smoked paprika, cumin, salt, and pepper. Cook the shrimp for about 5 minutes or until they are pink and opaque, stirring occasionally for even cooking.
Step 5: Assemble Crostini
Once the crostini have cooled slightly, spread a generous layer of the creamy avocado mixture on each slice. Carefully top each avocado layer with the sautéed garlic shrimp, ensuring each crostini is adorned with the savory flavor. Serve immediately, allowing your guests to enjoy these beautifully crafted garlic shrimp crostini with avocado while they are fresh and warm.

- Flavor Boost: Consider marinating shrimp in lime juice, smoked paprika, and cumin for 30 minutes prior to cooking for a deeper flavor profile.

Garlic Shrimp Crostini with Avocado Recipe FAQs
How do I choose the best avocados for this recipe?
Absolutely! Look for avocados that are firm yet slightly yielding when gently squeezed. A ripe avocado will have a deep green color with no dark spots or blemishes. If they’re too hard, allow them to ripen at room temperature for a couple of days. Once ripe, store them in the refrigerator to maintain their freshness.
How can I store leftover crostini?
Very good question! Store any leftover assembled garlic shrimp crostini in an airtight container and consume them within 1 hour for the best taste and texture. If you have unassembled components, keep the shrimp and the mashed avocado separately in the fridge. The shrimp can last for up to 3 days, while the avocado should ideally be eaten right after mashing to avoid browning.
Can I freeze the shrimp for this recipe?
Absolutely! To freeze your cooked shrimp, first let them cool completely. Place them in a freezer-safe bag or container and store them in the freezer for up to 3 months. When you’re ready to enjoy them, thaw the shrimp in the refrigerator overnight, then reheat them in a skillet over low heat until just warm. This ensures they remain tender and juicy!
What should I do if my shrimp are overcooked?
If your shrimp end up a bit overcooked, don’t worry! While they may have a rubbery texture, you can try making a shrimp salad by mixing them with more avocado, some mayo, or yogurt, and serving it as a dip. This way, you can still enjoy the flavors with a softer texture. For next time, remember, shrimp cook quickly—about 2 minutes per side is usually ideal!
Is this recipe suitable for those with seafood allergies?
Good thinking! Unfortunately, shrimp is not suitable for those with seafood allergies. If you want to provide an alternative, consider substituting the shrimp with grilled chicken or chickpeas—both can still offer a delicious topping that harmonizes with the creamy avocado while keeping the dish friendly for more guests.
