How to Make Asiago Asparagus Quiche

Prepare the Dough

In a food processor, combine all-purpose flour, whole wheat flour, and salt. Add olive oil and water, pulsing until the mixture resembles moist breadcrumbs. Turn onto a floured surface and gently knead into a ball. Wrap in plastic wrap and let rest for 1 hour at room temperature—this relaxes the gluten and makes rolling easier.

Prep the Vegetables

While the dough rests, finely dice the onion, trim and cut the asparagus, and mince the garlic. Grate Asiago cheese freshly for smooth melting. Bring the eggs to room temperature for an even custard.

Blind Bake the Crust

Preheat oven to 375°F. Roll dough into an 11-inch circle about 1/8-inch thick and transfer to a 9-inch pie dish. Fold overhanging edges and crimp. Line with parchment and fill with pie weights or dried beans. Bake 20 minutes, remove weights, and bake another 10 minutes until pale golden.

Sauté the Vegetables

Heat 1 tsp olive oil in a skillet over medium heat. Cook onions for 5 minutes until soft. Add asparagus and cook 5 minutes until tender-crisp. Add garlic and cook 1 minute more. Slightly undercooking ensures they won’t become mushy in the oven.

Assemble the Quiche

Spread sautéed vegetables evenly in the blind-baked crust. Scatter grated Asiago cheese over the top. In a bowl, whisk eggs, milk, Dijon mustard, thyme, salt, pepper, and nutmeg. Pour custard into the crust, filling about ½ inch from the rim.

Bake and Serve

Bake at 375°F for 30–35 minutes, until custard is set but slightly jiggly in the center. Golden brown on top. Let rest 15 minutes at room temperature to set the custard. Serve warm or at room temperature for the best flavor.

Tips for Success

• Rest the dough – Prevents shrinkage and makes rolling easier.
• Sauté vegetables lightly – Keeps them crisp and flavorful.
• Use room-temperature eggs – Ensures a smooth, even custard.
• Freshly grate Asiago – Melts better than pre-shredded.
• Rest quiche before slicing – Custard firms and slices cleanly.

Equipment Needed

• Food processor for the dough
• Rolling pin and floured surface
• 9-inch pie dish
• Parchment paper and pie weights or dried beans
• Skillet for sautéing vegetables
• Mixing bowls and whisk

Recipe Variations

• Cheddar and Broccoli Quiche – Substitute broccoli and cheddar for a classic flavor.
• Mushroom and Gruyère Quiche – Swap asparagus for mushrooms and Asiago for Gruyère.
• Herbed Goat Cheese Quiche – Add fresh herbs and creamy goat cheese for extra elegance.

Serving Suggestions

• Serve with a green salad or roasted vegetables.
• Pair with crusty bread or fresh fruit for brunch.
• Garnish with fresh thyme or microgreens for a beautiful presentation.

FAQs

Can I make this ahead of time?
Yes, assemble and refrigerate the quiche up to 24 hours before baking.

Can I use frozen asparagus?
Fresh is preferred, but thawed and drained frozen asparagus works. Sauté briefly to remove excess moisture.

Can I use pre-made pie crust?
Yes, for convenience, though homemade crust adds flavor and texture.

How do I know when the custard is done?
The center should be slightly jiggly but mostly set. It will firm as it cools.

Can I freeze slices?
Yes, wrap cooled slices tightly and freeze up to 2 months. Reheat gently in the oven.
