Sausage, Onion, and Portabella Mushroom Quiche

I still remember the first time I tasted quiche. I was a wide-eyed culinary student, and a guest chef, renowned for his elegant Parisian cuisine, had prepared a classic quiche Lorraine for our class. The creamy custard, the smoky bacon, and the buttery crust – it was a revelation! But it wasn’t just the flavors; it was the feeling of sophistication and simple elegance that the dish evoked. Since then, I’ve been experimenting with quiche recipes, eager to capture that magic while adding my own creative touch. This Sausage, Onion, and Portabella Mushroom Quiche is a testament to those experiments, a hearty and flavorful take on a classic that’s perfect for any occasion.

Recipe Overview

• Prep Time: 25 minutes
• Cook Time: 40 minutes
• Total Time: 1 hour 5 minutes
• Servings: 6
• Yield: 1 pie
• Dietary Type: Not Gluten-Free

Ingredients

• For the Crust:

  • 3/4 cup corn flake crumbs
  • 1 tablespoon butter, melted

• For the Filling:

  • 1 cup sweet Italian sausage, ground (will cook down to about 3/4 cup)
  • 1/2 cup sweet onion, finely diced
  • 3/4 cup portabella mushroom cap, sliced 1/4-inch thick, then chopped
  • 1 cup Swiss cheese, shredded
  • 5 eggs, beaten
  • 1 cup half-and-half cream
  • 1/4 teaspoon dried whole thyme
  • 1/4 teaspoon salt
  • 1/2 teaspoon fresh ground black pepper
  • 2 tablespoons chives, chopped

Equipment Needed

• 9-inch deep dish pie plate
• Non-stick skillet
• Mixing bowls
• Whisk
• Measuring cups and spoons
• Paper towels

Instructions

1. Preheat your oven to 350°F (175°C). Lightly spray a 9-inch deep dish pie plate with cooking oil and set aside.

2. Prepare the crust: In a small bowl, mix the corn flake crumbs with the melted butter. Using the back of a spoon, firmly press the mixture into the bottom (not the sides) of the pie plate. This creates a simple, slightly sweet base for the savory filling. Bake the crust for 5 minutes. This brief baking helps to set the crust and prevent it from becoming soggy. Remove from the oven and set aside.

3. Cook the sausage: In a medium-sized non-stick skillet, fry the ground sweet Italian sausage over medium heat until it is cooked through and browned. Use a fork to mash the sausage while cooking, breaking it into small crumbles. This ensures even distribution throughout the quiche. Once cooked, drain the sausage on several paper towels to remove excess grease. Set aside. You should have approximately 3/4 cup of cooked sausage.

4. Sauté the vegetables: Wipe the skillet dry using paper towels to remove any remaining sausage grease. Add the chopped portabella mushrooms and finely diced sweet onion to the skillet. Fry over medium heat until the onions begin to soften. Dry frying (cooking without added oil) will intensify the natural flavors of both the onions and the mushrooms, resulting in a more robust and flavorful quiche.

5. Assemble the filling: In the pre-baked corn flake crust, toss 3/4 cup of the cooked sausage with the sautéed mushrooms and onions, distributing evenly across the bottom of the crust. Sprinkle the shredded Swiss cheese over the sausage and vegetable mixture.

6. Prepare the custard: In a separate mixing bowl, whisk together the beaten eggs, half-and-half cream, dried thyme, salt, and fresh ground black pepper. Ensure the mixture is well combined. The thyme adds a subtle herbaceous note that complements the sausage and mushrooms beautifully.

7. Pour and bake: Carefully pour the egg and cream mixture into the pie plate, ensuring it evenly covers the sausage, vegetable, and cheese layers. Be careful not to disturb the crust while pouring. Sprinkle the chopped chives evenly over the top of the quiche.

8. Bake: Place the quiche in the preheated oven and bake at 350°F (175°C) for 35 minutes, or until the quiche is set and beginning to brown around the edges. The center should be slightly firm to the touch, with only a slight wobble.

9. Cool and serve: Remove the quiche from the oven and let it cool for at least 5 minutes before cutting and serving. This allows the quiche to set further and makes it easier to slice.

Expert Tips & Tricks

• Blind Baking Boost: For an even crispier crust, consider blind baking the corn flake crust before adding the filling. Place parchment paper and pie weights (or dried beans) in the crust during the initial baking for 10 minutes, then remove the paper and weights and bake for the final 5 minutes as directed.
• Sausage Swap: If you prefer a spicier quiche, substitute the sweet Italian sausage with hot Italian sausage, or even chorizo.
• Vegetable Variety: Feel free to experiment with other vegetables. Spinach, asparagus, or bell peppers would all be delicious additions. Just be sure to pre-cook any vegetables with high water content to prevent a soggy quiche.
• Cheese Please: Gruyere or provolone cheese can be substituted for the Swiss cheese. Each cheese will add a unique flavor profile to the quiche.
• Even Cooking is Key: Rotate the quiche halfway through baking to ensure even browning and cooking.
• Prevent a Soggy Bottom: To avoid a soggy crust, ensure that your cooked sausage and vegetables are well-drained before adding them to the pie shell. Any excess moisture can seep into the crust and make it soggy.

Serving & Storage Suggestions

This Sausage, Onion, and Portabella Mushroom Quiche is delicious served warm or at room temperature. It’s a perfect brunch dish, a satisfying lunch, or a light dinner. Garnish with a few extra chopped chives for a pop of color.

To store leftovers, allow the quiche to cool completely, then wrap it tightly in plastic wrap or store it in an airtight container. It will keep in the refrigerator for up to 3 days. To reheat, warm it in the oven at 350°F (175°C) for about 10-15 minutes, or until heated through. You can also reheat individual slices in the microwave, but the crust may become slightly less crisp.

The quiche can also be frozen for longer storage. Wrap individual slices tightly in plastic wrap and then place them in a freezer bag. Frozen quiche will keep for up to 2 months. To reheat, thaw it in the refrigerator overnight, then bake it in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through.

Variations & Substitutions

• Gluten-Free Crust: For a gluten-free option, use a gluten-free pie crust recipe or purchase a pre-made gluten-free pie crust.
• Crustless Quiche: For a lighter option, skip the crust altogether and bake the filling in a greased pie plate. Reduce the baking time by about 5-10 minutes.
• Dairy-Free: Substitute the half-and-half cream with a plant-based milk alternative, such as almond or soy milk. The texture may be slightly different. You can also use dairy-free cheese.
• Vegetarian: Omit the sausage and add more vegetables, such as spinach, bell peppers, or zucchini.
• Seasonal Variations: Adapt the recipe to the seasons by using seasonal vegetables. Asparagus in the spring, tomatoes in the summer, and butternut squash in the fall would all be delicious.
