Ingredients

• Sourdough Crust: 6 slices sourdough bread (crusts removed), 2 tbsp unsalted butter (melted)
• Vegetables: 1 cup asparagus (trimmed and cut into 1-inch pieces), 1 cup cremini or button mushrooms (sliced), 1 small shallot (finely chopped), 2 tbsp olive oil
• Egg Mixture: 8 large eggs, 1/3 cup whole milk, 1/4 cup heavy cream, 1/2 cup grated Gruyère cheese, 1/4 cup grated Parmesan cheese, 2 tbsp fresh chives (chopped), 1/2 tsp salt, 1/4 tsp ground black pepper

Instructions

Step 1: Prepare the pan and crust

Preheat oven to 375°F (190°C). Grease a 9-inch (23 cm) springform pan or deep pie dish.

Step 2: Create the sourdough base

Arrange the sourdough slices to fully line the bottom and sides of the pan, overlapping slightly. Brush with melted butter. Bake for 8–10 minutes until just crisp. Remove and set aside.

Step 3: Sauté the vegetables

Heat olive oil in a skillet over medium heat. Sauté shallot for 1–2 minutes until fragrant. Add mushrooms and cook until softened, about 4 minutes. Add asparagus and sauté for 2–3 more minutes. Remove from heat.

Step 4: Prepare the egg mixture

In a large bowl, whisk together eggs, milk, cream, Gruyère, Parmesan, chives, salt, and pepper until well combined.

Step 5: Assemble the frittata

Spread the sautéed vegetables evenly over the sourdough crust. Pour the egg mixture over the vegetables.

Step 6: Bake to perfection

Bake for 25–30 minutes, or until the frittata is puffed and golden and the center is just set. Cool for 5 minutes before slicing.

Step 7: Serve

Serve warm or at room temperature.

Zusatztipps für die Zubereitung

For the crispiest sourdough crust, make sure to remove the crusts from your bread slices and arrange them in a single, overlapping layer that fully covers the bottom and sides of your pan. The melted butter is essential for achieving that golden, crispy texture. When sautéing the vegetables, avoid overcooking the asparagus—it should remain bright green and slightly tender, as it will continue to cook in the oven. Let the frittata cool for at least 5 minutes before slicing to allow the eggs to set fully, which makes for cleaner, more beautiful slices.

Varianten und Anpassungen

This frittata is wonderfully versatile and can be adapted to suit different dietary needs and taste preferences. For a dairy-free version, substitute plant-based milk and cheese alternatives—cashew-based cheeses work particularly well. If you'd like to add protein, cooked pancetta or smoked salmon make excellent non-vegetarian additions. You can also swap the asparagus for other seasonal vegetables like zucchini, bell peppers, or spinach. For a different flavor profile, try using fresh thyme or basil instead of chives, or experiment with different cheese combinations such as aged cheddar or fontina.

Serviervorschläge

This Asparagus and Mushroom Frittata with Sourdough Crust is excellent served with a fresh green salad dressed in a light vinaigrette to balance the richness of the eggs and cheese. For beverages, pair it with a crisp white wine such as Sauvignon Blanc or a light Pinot Grigio. It also works beautifully as part of a brunch spread alongside fresh fruit, roasted tomatoes, or a simple arugula salad. The frittata can be served warm straight from the oven or at room temperature, making it perfect for picnics, potlucks, or make-ahead meals.
