Stuffed Mushroom Prawn Cups with Avocado

An elegant cold appetizer featuring tender mushroom caps hollowed and filled with creamy avocado mixture, topped with succulent prawns. This dish combines clean, fresh flavors with a sophisticated presentation perfect for entertaining. The avocado provides buttery richness while the prawns add briny sweetness and protein. Tangy yogurt-Worcestershire sauce ties everything together with umami depth. Red chili brings gentle heat, and crisp lettuce adds textural contrast.

The version here skips heavy mayonnaise bases common in retro versions, letting quality ingredients shine through with a fresher, modern approach suitable for contemporary palates.

Tips
Use uniform mushroom sizes so cavities fill evenly and caps sit level on the platter. Trim thick stalks completely but keep cap structure intact for structural support.
Prepare components separately up to two hours ahead: mashed avocado (cover directly with plastic to prevent browning), sauce in a bowl, and mushrooms cleaned and dried. Assemble only minutes before serving to prevent soggy mushrooms.
Drizzle sauce on the platter beneath mushrooms rather than directly on top, which keeps caps crisp and allows guests to control sauce intensity while eating.
Good to Know
Refrigerate component parts separately for up to 8 hours. Avocado mixture must be covered directly with plastic wrap to prevent oxidation. Assembled mushrooms do not store well due to moisture absorption.
Prepare avocado mixture, yoghurt sauce, and shredded lettuce up to 2 hours ahead. Keep avocado covered with plastic touching surface. Clean and hollow mushrooms earlier in day. Assemble and top with prawns only within 15 minutes of serving.
Arrange on a chilled platter. Serve immediately as a passed appetizer or seated first course. Pairs with crisp white wine, champagne, or a light seafood-friendly rosé.
Common Mistakes
Use mushrooms that are too small or select varying sizes to avoid uneven cavities and unstable presentation
Skip lemon juice on avocado to avoid rapid browning and oxidation; acid is essential even if not immediately noticeable
Assemble too far ahead to avoid soggy caps from lettuce and mushroom moisture release

FAQ
Can I make these ahead for a party?
Prepare all components separately up to 2 hours prior: avocado mixture (covered), sauce chilled, lettuce shredded, and mushrooms cleaned. Assemble and top with prawns within 15 minutes of serving to prevent caps from becoming soggy and soft.
What if I don't have Greek yoghurt?
Sour cream works 1:1 with slightly thinner consistency and tangier bite. Cashew cream offers a vegan option at 0.75:1 ratio but requires advance soaking. Mayo-based sauces alter the fresh profile this recipe emphasizes.
Can I freeze leftover stuffed mushrooms?
Not recommended. Mushrooms become mushy and watery when thawed, prawns toughen, and avocado oxidizes and separates. Store components separately and consume within hours of assembly for best texture and flavor.
