The Unexpected Delight: Avocado and Mushroom Quiche

My grandmother, a woman who approached cooking with a delightful blend of intuition and daring, used to say that the best dishes are often born from unexpected pairings. I remember one rainy afternoon, she threw together a frittata using leftover roasted mushrooms and a perfectly ripe avocado. The result was an epiphany – the earthy mushrooms dancing with the creamy avocado, all held together by the richness of the eggs. This avocado and mushroom quiche, a tribute to that serendipitous creation, captures the same harmonious blend of flavors, offering a comforting and surprisingly elegant dish perfect for any occasion.

Total Time: 40 minutes
Servings: 4
Yield: 1 Quiche
Dietary Type: Vegetarian

Ingredients

6 ounces portabella mushrooms
1 1/2 ounces butter
1-2 teaspoons curry powder, dependent on taste and heat of powder
Salt, to season
1 (8 ounce) avocado
3 tablespoons finely chopped green onions (spring)
3 eggs
3/4 cup heavy cream
1/4 teaspoon salt, extra
White pepper, to taste
3 tablespoons dry white wine
1 tablespoon tomato ketchup

Equipment Needed

8-9″ diameter china quiche dish or shallow round ovenproof dish
Skillet
Whisk

Instructions

Begin by preheating your oven to 350°F (175°C). This ensures even cooking and prevents the quiche from becoming soggy.
Next, prepare your baking dish. Generously butter an 8-9″ diameter china quiche dish or shallow round ovenproof dish. This will prevent the quiche from sticking and make serving a breeze.
Prepare the mushrooms. Wipe the portabella mushrooms clean with a damp cloth, if necessary. Then, slice them thickly. The thickness will allow them to retain some texture during cooking.
Sauté the mushrooms. Melt the butter in a skillet over high heat. Add the sliced mushrooms and cook, stirring constantly, until they have just softened – this should take about a minute. Avoid overcrowding the pan; cook in batches if needed to ensure they brown properly.
Introduce the curry. Add the curry powder to the skillet and sauté for a few seconds longer, allowing the spices to bloom and release their aroma. Season with a pinch of salt. The amount of curry powder should be adjusted to your preference, keeping in mind the heat level of your chosen curry powder.
Assemble the base. Transfer the sautéed mushrooms to the prepared dish and spread them evenly over the base. This forms the delicious foundation of your quiche.
Add the avocado. Peel the avocado, remove the pit, and cut it into slices. Arrange the avocado slices attractively over the mushrooms. The creamy avocado provides a wonderful contrast to the earthy mushrooms.
Scatter the green onions. Sprinkle the finely chopped green onions evenly over the mushrooms and avocado. These add a touch of freshness and a subtle bite.
Prepare the egg mixture. In a bowl, combine the eggs, heavy cream, extra salt, white pepper, dry white wine, and tomato ketchup. Beat vigorously with a whisk until well combined and slightly frothy. The wine adds complexity, and the ketchup provides a hint of sweetness and color.
Pour and bake. Gently pour the egg mixture over the top of the avocado and mushrooms, ensuring it evenly distributes. Place the dish in the preheated oven.
Bake. Cook for approximately 25 minutes, or until the quiche has lightly set in the middle. A slight jiggle is okay; it will continue to set as it cools.
Cool and serve. Remove from the oven and let the quiche stand for 5 minutes before cutting into wedges and serving. This allows the quiche to settle and makes slicing easier.

Expert Tips & Tricks

Spice Level: If you prefer a spicier quiche, add a pinch of cayenne pepper to the egg mixture or use a hotter curry powder.
Mushroom Prep: Don’t wash mushrooms directly under running water, as they will absorb the water and become soggy. Instead, wipe them clean with a damp paper towel.
Even Cooking: To ensure even cooking, rotate the quiche halfway through the baking time.
Preventing a Soggy Bottom: While this is a crustless quiche, you can still prevent a soggy bottom by preheating the baking dish in the oven for a few minutes before adding the filling.
Make-Ahead Tip: You can prepare the mushroom mixture and slice the avocado ahead of time. Store them separately in the refrigerator until ready to assemble the quiche.

Serving & Storage Suggestions

Serve the avocado and mushroom quiche warm or at room temperature. It pairs beautifully with a light salad or a side of roasted vegetables. For a brunch setting, consider serving it with fresh fruit and a mimosa.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. While it can be served cold, its best within the first 1-2 days. Freezing is not recommended, as the texture may change upon thawing.
