Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Shrimp
Shrimp are the star of this dish, offering a naturally sweet and tender base. Medium to large shrimp work best, as they provide a satisfying bite and are easy to cook quickly without becoming rubbery.

Garlic
Fresh garlic adds depth and aroma to the shrimp. I strongly recommend using freshly minced garlic rather than pre-packaged versions, as it delivers a more vibrant and authentic flavor.

Olive Oil
Olive oil helps sauté the shrimp evenly while adding subtle richness. A good-quality olive oil enhances the overall taste without overpowering the other ingredients.

Butter
Butter brings a silky finish to the shrimp and balances the sharpness of the garlic. Using a small amount is enough to elevate the dish.

Red Pepper Flakes
Red pepper flakes add a gentle heat that complements the sweetness of the shrimp. You can adjust the quantity depending on your spice tolerance.

Salt
Salt is essential for seasoning the shrimp and enhancing all the flavors. Season lightly at first and adjust after cooking.

Black Pepper
Freshly ground black pepper provides warmth and a subtle bite that pairs well with garlic and shrimp.

Lemon Juice
Lemon juice brightens the dish and cuts through the richness of the butter and avocado. Freshly squeezed lemon juice is always preferable.

Avocado
Avocado adds creaminess and a mild, buttery flavor. Choose ripe but firm avocados to ensure a smooth yet structured topping.

Bread
A crusty baguette or similar bread is ideal for crostini. Sliced and toasted, it provides the necessary crunch and structure.

Fresh Parsley
Parsley adds a fresh, herbaceous finish and a pop of color that makes the crostini visually appealing.

Directions

Start by preparing the crostini. Slice the bread into even pieces and lightly brush each slice with olive oil. Toast them in the oven at 375°F (190°C) for about 8 to 10 minutes, or until golden and crisp. Set aside to cool slightly.

Next, heat olive oil and butter in a skillet over medium heat. Once the butter has melted, add the minced garlic and red pepper flakes. Sauté briefly until fragrant, taking care not to brown the garlic. Add the shrimp in a single layer and season with salt and black pepper. Cook for 2 to 3 minutes per side, until the shrimp turn pink and opaque. Remove from heat and finish with fresh lemon juice.

Mash the avocado lightly with a pinch of salt and a splash of lemon juice. Spread a generous layer of avocado onto each crostini. Top with the garlic shrimp and spoon a little of the pan juices over each piece. Garnish with fresh parsley and serve immediately.

Storage/reheating

Crostini are best enjoyed fresh. If needed, store shrimp and avocado separately in airtight containers in the refrigerator for up to one day. Reheat shrimp gently in a skillet and assemble just before serving.

Variations and Customizations

This recipe is highly adaptable, making it easy to tailor to your preferences. For a Mediterranean twist, add chopped sun-dried tomatoes or olives to the avocado mixture. If you enjoy smoky flavors, a pinch of smoked paprika added to the shrimp works beautifully. I also tried this recipe with whole-grain bread, which added a nutty undertone and extra texture. For a dairy-free option, simply omit the butter and use additional olive oil. You can also substitute shrimp with sautéed mushrooms or grilled vegetables for a vegetarian version. Each variation maintains the core balance of creamy, savory, and crisp elements.
