Sour Cream Quiche Recipe: Flaky Crust with Creamy Custard Centers

This sour cream quiche delivers the flakiest crust and most creamy custard center you’ll ever make at home. The secret lies in blind-baking the crust to prevent sogginess and using full-fat sour cream for that signature velvety texture.

The filling comes together quickly with eggs, milk, and your choice of mix-ins, creating a rich but balanced custard. A preheated oven ensures even cooking and a golden finish that’s as beautiful as it is delicious.

What you’ll get is a quiche with a buttery, shatteringly crisp base and a center so smooth it melts on the tongue. It’s perfect for brunches, light dinners, or even meal prep.

Bake it once, and this will become your go-to recipe for impressive, foolproof results every time.

Ingredients for Sour Cream Quiche

Flaky crust meets creamy custard with these simple quality ingredients for your next brunch star.

The crust hinges on cold butter—European-style from Whole Foods gives the best flakiness. I always use King Arthur Flour for consistency, but any all-purpose works. For the sour cream, full-fat Daisy or Breakstone’s (the good stuff, not light) is non-negotiable for that velvety texture. The cheese? Gruyere at the deli counter—ask them to shred it fresh so it melts beautifully.

No Gruyere? Swiss or Emmental work great. Out of whole milk? Half-and-half at half the amount keeps it rich. Want to skip the bacon (or keep it veg)? Sautéed mushrooms or spinach at 1 cup chopped are perfect. The Dijon can be swapped for whole-grain mustard (same amount), but don’t skip it—it adds depth without overpowering.

Blind-baked crusts keep 2 days at room temp, wrapped tight. The filling? Prep it the night before and store in the fridge. Leftovers taste great cold or warmed for 3-4 days (cover with foil). Freeze slices for up to 2 months—perfect for busy mornings.

Step-by-Step Instructions for Sour Cream Quiche

Here’s how to get that flaky crust and creamy filling with every bite.

Step 1: Prepare the Flaky Pie Crust

In a large bowl, combine the 1.5 cups all-purpose flour and 0.5 tsp salt. Cut in the 0.5 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces.

Gradually add the 6 tbsp ice water, one tablespoon at a time, mixing just until the dough comes together. Don’t overwork it—you want visible butter flakes for that flaky texture. Form into a disk, wrap in plastic, and chill for 30 minutes.

Step 2: Blind Bake the Crust

Roll out the chilled dough on a lightly floured surface to fit a 9-inch pie dish. Crimp the edges, then prick the bottom all over with a fork. Freeze for 15 minutes to prevent shrinking.

Preheat oven to 375°F. Line the crust with parchment paper, fill with pie weights or dried beans, and bake for 15 minutes. Remove weights and bake 5-8 minutes more until lightly golden. Cool slightly.

Step 3: Make the Creamy Custard Filling

In a large bowl, whisk together the 4 whole large eggs, 1 cup full-fat sour cream, and 0.5 cup whole milk until smooth. Stir in the 1 tsp Dijon mustard, 0.25 tsp black pepper, and 0.125 tsp nutmeg.

Add the 1 cup shredded Gruyere cheese and 0.5 cup shredded sharp cheddar cheese, then fold in the 0.5 cup cooked crumbled bacon and 2 tbsp chopped fresh chives. This creates a rich, velvety base with perfect seasoning.

Step 4: Bake to Golden Perfection

Pour the filling into the pre-baked crust. Bake at 375°F for 35-40 minutes until the center is just set with a slight jiggle and the top is golden brown. Don’t overbake—the custard continues to set as it cools.

Let rest for 10-15 minutes before slicing. This allows the filling to firm up while staying creamy. Serve warm or at room temperature for the best texture and flavor.

Essential Equipment for Great sour cream quiche

Pie Dish Selection

I always use a 9-inch glass pie dish like Pyrex for even heat distribution and easy monitoring of the crust’s browning. Metal pans work too, but may require 2-3 minutes less baking time. Avoid dark-colored pans which can overbrown the bottom. 💡

Pastry Tools

A pastry cutter makes quick work of cutting butter into flour, but two forks work in a pinch. I love my OXO Good Grips cutter for comfort. For rolling, a marble rolling pin stays cool, preventing butter from melting prematurely.

Blind Baking Essentials

Pie weights are non-negotiable for a crisp crust. I use ceramic pie weights from RSVP International, but dried beans work too. Parchment paper prevents sticking—cut a 12-inch square for full coverage. Always preheat your oven for 15 minutes.

Mixing Bowls

A set of nested stainless steel bowls (I use Cuisinox) makes whisking the custard effortless. A large 3-quart bowl gives enough room for all ingredients. For the dough, a wide, shallow bowl helps cut in the butter evenly.

Precision Measurement

Accurate measurements matter for both crust and filling. I swear by my OXO stainless steel measuring cups and adjustable measuring spoon. For the nutmeg, a microplane grater gives the perfect fine texture. 🔥

Cooling Rack

Let your quiche cool properly on a wire rack to prevent sogginess. I use a foldable silicone-coated rack from Checkered Chef. This allows air circulation underneath, keeping the crust crisp while the filling sets.
