Step‑by‑Step Instructions for Tarragon Chicken Salad Crostini
Step 1: Infuse the Oil
Start by grinding dried tarragon into a fine powder using a spice grinder or mortar and pestle. Combine the powdered tarragon with avocado oil and sunflower lecithin in an infusion machine. Set the machine to heat at 160℉ for one hour. Once done, strain the oil through a fine mesh sieve to remove the tarragon, and set the infused oil aside for later use.
Step 2: Prepare the Mayonnaise
In a mixing bowl, whisk together the egg yolk and fresh lemon juice until frothy and slightly thickened, about 1-2 minutes. Gradually drizzle in the tarragon-infused oil while continuously whisking to create a smooth emulsion. Continue whisking until soft peaks form, indicating the mayonnaise is thick and creamy. Adjust with salt to taste for the best flavor in your tarragon chicken salad.
Step 3: Combine the Chicken Salad
Now, fold the cooked chicken into your freshly made mayonnaise in a large mixing bowl. Add in the stone ground mustard, salt, and pepper, gently mixing until all ingredients are fully incorporated. Ensure the chicken is evenly coated with the creamy mayo mixture. Taste and adjust any seasoning as needed before moving on to assemble your crostini.
Step 4: Toast the Baguette
Preheat your oven’s broiler to high. While it heats up, slice the baguette into ½-inch thick pieces. Brush each slice generously with the reserved tarragon-infused oil, ensuring a nice coating. Once the broiler is ready, place the baguette slices on a baking sheet and toast them for about 6-8 minutes, flipping halfway through until they are golden brown and crispy.
Step 5: Assemble the Crostini
Remove the toasted baguette slices from the oven and let them cool slightly. Spoon a generous portion of the tarragon chicken salad onto each slice, ensuring it’s heaped high for an impressive presentation. Garnish each crostini with vibrant rainbow microgreens for a fresh touch. Serve immediately to enjoy the perfect blend of textures and flavors in this elegant appetizer.

How to Store and Freeze Tarragon Chicken Salad

Assemble Later: Keep crostini and chicken salad separate until serving to maintain the baguette’s crispiness. Assemble just before serving for the best texture and flavor.

Tarragon Chicken Salad Crostini Recipe FAQs
What type of tarragon should I use?
You can use either dried or fresh tarragon for your salad. Dried tarragon is easily available and infuses a wonderful flavor, but fresh tarragon brings a brighter, more aromatic punch. If you’re using fresh, simply use about three times the amount since it’s less potent than dried.
How long can I store leftover chicken salad?
Store any leftover tarragon chicken salad in an airtight container in the fridge for up to 3 days. This keeps it fresh and ready for quick snacks or meals. Just be sure not to mix it with the crostini until you’re ready to serve, as this will keep the bread crispy and delicious!
Can I freeze the chicken salad?
Absolutely! You can freeze the tarragon chicken salad for up to 2 months. Just be sure to place it in a well-sealed container to avoid freezer burn. When you’re ready to enjoy, simply transfer it to the fridge for a slow thaw overnight. Note that the texture may vary slightly after freezing, but the flavor will remain delightful!
How do I prevent the mayonnaise from splitting?
Great question! To ensure your mayonnaise emulsifies perfectly, it’s essential to add the tarragon-infused oil gradually while whisking vigorously. Start by combining the egg yolk and lemon juice until frothy, then slowly drizzle in the oil. Keep whisking continuously until you achieve soft peaks. If it starts to split, adding a teaspoon of warm water while whisking can help rescue it!
Any dietary considerations for pets or allergies?
Yes, if you have allergies to eggs or mustard, consider using an egg-free mayo alternative for this tarragon chicken salad. For pet owners, keep this dish away from your furry friends, especially due to the egg content. Always double-check your ingredient labels to ensure safety if there are specific allergies in your household.
Can I make this dish vegan or vegetarian?
Certainly! You can substitute the chicken with shredded chickpeas or a plant-based protein, and use a vegan mayonnaise to keep the flavors. If you’re creating a vegetarian version, the addition of hearty vegetables like celery or bell peppers can add crunch and heartiness, making it a satisfying meal or snack.
