Sour Cream Quiche Recipe: Flaky Crust With Creamy Custard

There’s a reason this quiche stands out—it delivers a flaky crust with a creamy custard that’s both rich and balanced. Sour cream is the secret to that velvety texture.

Baking at the right temperature ensures the crust stays crisp while the filling sets perfectly. Simple ingredients, professional results every time.

Ingredients for Sour Cream Quiche

A dozen quality ingredients deliver that signature flaky crust and creamy custard everyone loves.

The butter must be cold—Land O’Lakes or Kerrygold for best results. Use King Arthur Flour if available; its consistent protein content ensures a tender, flaky crust. Sour cream is non-negotiable for that velvety texture—Daisy or Breakstone’s are reliable brands. For the Gruyère, a Whole Foods or specialty cheese counter will have the best selection. Avoid pre-shredded cheese as it contains anti-caking agents that affect melt.

No Gruyère? Emmental or Comté work well, or use all cheddar for a sharper flavor. Half-and-half can replace milk for extra richness. Fresh chives are ideal, but green onions at half the amount work in a pinch. The nutmeg adds a subtle depth—skip it if you dislike the flavor. For a lighter version, substitute low-fat sour cream, but the texture won’t be as luxurious.

The crust dough can be made 2 days ahead and refrigerated. Baked quiche keeps 3-4 days in the fridge or can be frozen for up to 2 months. Reheat slices in a toaster oven to maintain the crust’s crispness. Always bring ingredients to room temperature before assembling for even baking.

Step-by-Step Instructions for Sour Cream Quiche

Master the technique for a buttery crust and velvety custard that sets perfectly every time.

Step 1: Prepare the Flaky Pie Crust

In a food processor, pulse the 1.5 cups all-purpose flour with 0.5 tsp salt to combine. Add the 0.5 cup unsalted butter, cubed and chilled, and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces visible. This texture ensures flaky layers in your finished crust.

With the processor running, drizzle in the 0.25 cup ice water through the feed tube until the dough just begins to come together. It should hold when pressed but not be sticky. Turn the dough onto a lightly floured surface, shape into a disk, wrap in plastic, and refrigerate for 30 minutes to relax the gluten.

Step 2: Blind-Bake the Crust

On a floured surface, roll the chilled dough into a 12-inch circle and transfer it to a 9-inch pie dish. Crimp the edges decoratively, then prick the bottom all over with a fork. Freeze for 15 minutes to prevent shrinking during baking.

Line the crust with parchment paper and fill with pie weights or dried beans. Bake at 375°F for 15 minutes, then remove the weights and parchment. Continue baking for 8-10 minutes until the crust is light golden brown and completely dry to the touch. This prevents a soggy bottom.

Step 3: Make the Creamy Custard Filling

In a large bowl, whisk together the 4 whole large eggs until frothy. Add the 1.5 cups sour cream, 0.5 cup whole milk, and remaining 0.25 tsp salt, whisking until fully incorporated. The mixture should be smooth and pale yellow with no streaks of egg visible.

Stir in the 1.5 cups shredded Gruyère cheese, 0.5 cup shredded sharp cheddar cheese, 0.25 tsp ground black pepper, and 0.125 tsp ground nutmeg. The nutmeg adds a subtle warmth that complements the cheeses beautifully. Let the mixture rest for 5 minutes to allow the flavors to meld.

Step 4: Assemble and Bake the Quiche

Pour the custard filling into the pre-baked crust, spreading it evenly. Sprinkle the 0.25 cup fresh chives over the top for a pop of color and mild onion flavor. Place the quiche on a baking sheet to catch any potential spills.

Bake at 350°F for 40-45 minutes until the center is just set with a slight jiggle (it will continue cooking as it cools) and the top is golden brown. Avoid overbaking, as this can cause the custard to curdle. The quiche is done when a knife inserted in the center comes out clean.

Step 5: Cool and Serve

Let the quiche cool in the pan on a wire rack for 15 minutes before slicing. This resting period allows the custard to set fully and makes for cleaner slices. The texture should be silky and rich, with the crust maintaining its crispness.

Serve warm or at room temperature, garnished with additional fresh chives if desired. For best results, consume within 2 days—though the flavors deepen beautifully overnight. Reheat individual slices in a 300°F oven for 10 minutes to restore the crust’s crispness.

Essential Equipment for This Dish

Pie Dish Essentials

I always use a 9-inch glass pie dish—Pyrex is my go-to brand because it heats evenly and lets me monitor the crust’s browning. The transparency helps you see when the bottom is perfectly golden without lifting it. 💡

Rolling Pin Choice

A French-style tapered rolling pin gives me the most control for rolling out that buttery dough to an even ⅛-inch thickness. I prefer the J.K. Adams maple wood pin—it’s sturdy and doesn’t stick like some plastic versions.

Food Processor

For the flakiest crust, a food processor is non-negotiable. I’ve had my Cuisinart 14-cup for years—it cuts the cold butter into the flour perfectly in seconds, which keeps the dough cold and prevents tough crust.

Pie Weights

Blind-baking requires weights to prevent puffing. I use ceramic pie weights but dried beans work in a pinch. Fill the crust completely to the edges for even pressure. RSVP International makes durable stainless steel weights that last forever.

Line your crust with parchment first to make removal easy.

Whisk and Bowls

A good balloon whisk ensures your custard is silky smooth. I use OXO’s 11-inch whisk—it reaches the bowl’s edges perfectly. For mixing, a large stainless steel bowl gives plenty of room to whisk vigorously without spills. 🥄
