• 1 teaspoon salt
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• ½ teaspoon black pepper
• ¼ to ½ teaspoon cayenne pepper (depending on desired heat level)

Equipment Needed

Before we start cooking, make sure you have these items ready:

• Large skillet (preferably cast iron for the best blackening effect)
• Cutting board and sharp knife
• Mixing bowls
• Fork or potato masher for the avocado
• Paper towels
• Serving platter

Preparation Instructions

Step 1: Prepare the Cucumber Rounds

1. Wash the cucumbers thoroughly and pat dry with paper towels.
2. Slice the cucumbers into ½-inch thick rounds. You should get about 24-30 rounds.
3. Using a small spoon or melon baller, scoop out a small depression in the center of each cucumber round, creating a little “cup” for the avocado spread. Don’t go all the way through.
4. Place the cucumber rounds on paper towels to remove excess moisture while you prepare the other components.

Step 2: Make the Avocado Spread

1. Cut the avocados in half, remove the pits, and scoop the flesh into a medium bowl.
2. Add the lime juice, diced jalapeño (if using), chopped cilantro, and garlic powder.
3. Using a fork, mash the avocado mixture until smooth but still slightly chunky.
4. Season with salt and pepper to taste. Cover tightly with plastic wrap (pressed directly onto the surface to prevent browning) and refrigerate until ready to use.

Step 3: Prepare and Cook the Blackened Shrimp

1. If making your own blackening seasoning, mix all the spices in a small bowl.
2. Pat the shrimp dry with paper towels.
3. In a bowl, toss the shrimp with olive oil, minced garlic, and lemon juice.
4. Sprinkle the blackening seasoning over the shrimp and toss until evenly coated.
5. Heat a large skillet (preferably cast iron) over medium-high heat until very hot.
6. Add the seasoned shrimp to the hot skillet in a single layer. Cook for about 2 minutes on each side until the shrimp are pink, opaque, and slightly charred.
7. Remove from heat and let cool slightly.

Step 4: Assemble the Cucumber Bites

1. Arrange the cucumber rounds on a serving platter.
2. Spoon about 1 teaspoon of the avocado spread onto each cucumber round, filling the depression.
3. Top each with a blackened shrimp.
4. Garnish with fresh dill, chopped chives, and microgreens if using.
5. Serve with lime wedges on the side.

Expert Tips for Perfect Cucumber Bites

After making these numerous times for different occasions, I’ve gathered some tips and tricks that will help you achieve the best results:

• Choose the right cucumbers: English cucumbers (also called hothouse cucumbers) work best because they have fewer seeds and a firmer texture than regular cucumbers.
• Pat the cucumbers dry: This prevents the appetizers from becoming watery.
• Don’t skip the lime juice in the avocado spread: It not only adds flavor but also helps prevent the avocado from browning.
• Temperature matters: For the best blackening effect, make sure your skillet is very hot before adding the shrimp.
• Don’t overcrowd the pan: Cook the shrimp in batches if necessary to ensure they blacken properly.
• Make-ahead strategy: Prepare the cucumber rounds and blackening seasoning up to 24 hours ahead. Cook the shrimp and make the avocado spread up to 2 hours before serving. Assemble just before serving for the freshest presentation.

The Science Behind Blackening

What makes blackened shrimp so delicious? Let me share a bit about the science behind this cooking technique:

Blackening is a cooking method popularized by Chef Paul Prudhomme in the 1980s. It involves coating protein (traditionally fish or chicken) with spices and cooking it in a very hot cast-iron skillet. The intense heat causes the spices to char quickly, creating a distinctive crust that’s packed with flavor.

The magic happens through the Maillard reaction—a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. When the seasoned shrimp hits the hot pan, this reaction creates hundreds of different flavor compounds, resulting in that complex, slightly smoky taste that’s impossible to achieve through other cooking methods.

For the best blackening results:

1. Make sure your pan is extremely hot before adding the shrimp
2. Use a heavy-bottomed pan that retains heat well (cast iron is ideal)
3. Don’t overcrowd the pan, as this lowers the temperature and results in steaming rather than blackening
4. Cook in a well-ventilated area, as blackening can produce some smoke

Frequently Asked Questions

After sharing this recipe with friends and family, these are the questions I get asked most often:

Can I make these cucumber bites ahead of time for a party? You can prepare all components ahead of time, but I recommend assembling them no more than 30 minutes before serving. The cucumbers will release moisture and the avocado may start to oxidize if they sit too long after assembly.

How spicy is the blackened shrimp? The spice level is adjustable based on your preference. As written, the recipe has a medium heat level. For milder bites, reduce the amount of cayenne in the blackening seasoning. For spicier bites, increase the cayenne or add a pinch of ground habanero.

Can I use frozen shrimp? Yes! Just make sure to thaw them completely and pat them very dry before seasoning. Excess moisture will prevent proper blackening.

What can I use instead of avocado if I have an allergy? A mixture of cream cheese (softened) with herbs works well as an alternative. You could also use hummus or a puree of edamame with similar seasonings.

How do I keep the cucumber rounds from getting soggy? After slicing the cucumbers, place them on paper towels for about 15 minutes to draw out excess moisture. You can also sprinkle them lightly with salt to help draw out more moisture, then pat dry before filling.

Can I use regular cucumbers instead of English cucumbers? Yes, but I recommend peeling them first as the skin can be bitter. Also, you may want to scoop out the seeds before slicing them into rounds, as regular cucumbers typically have more seeds than English cucumbers.

Is there a way to make this recipe vegan? Absolutely! Replace the shrimp with blackened hearts of palm or blackened tofu cubes. The rest of the recipe is already plant-based.

What can I do with leftover blackening seasoning? Store it in an airtight container and use it for blackened fish, chicken, tofu, or vegetables. It’s also delicious sprinkled on roasted potatoes or stirred into homemade salad dressings for a kick of flavor.

Special Occasion Ideas

These elegant appetizers are perfect for various gatherings. Here are some specific occasions where they would shine:

The Environmental Benefit

One aspect I love about this recipe is its sustainability potential. By making mindful choices about your ingredients, you can create a dish that’s not only delicious but also environmentally responsible:

• Choose sustainable shrimp: Look for shrimp certified by the Marine Stewardship Council (MSC) or labeled as sustainably farmed.
• Use locally grown cucumbers and herbs: This reduces the carbon footprint of your appetizer.
• Reduce food waste: The cucumber centers you scoop out can be saved for salads or added to smoothies.
• Compost scraps: Avocado pits and peels, herb stems, and garlic skins can all be composted.
