Bacon, Swiss Cheese, and Spinach Quiche Recipe: Flaky Crust With Melty Triple Layers

This bacon Swiss cheese quiche recipe delivers the perfect balance of crispy crust, smoky bacon, and melty triple layers of Swiss and spinach—transforming breakfast into a satisfying meal.

The secret lies in a buttery, flaky crust that holds its shape while the filling bakes to golden perfection, creating a harmonious blend of textures and flavors that'll have everyone asking for seconds.

What sets this quiche apart is the bacon-Swiss cheese combo, which adds a rich, savory depth that pairs beautifully with the earthy spinach. The Swiss melts into creamy ribbons, while the bacon renders its fat into the custard, infusing every bite with smoky flavor.

Unlike traditional quiches, this version stays cohesive as a standalone dish, making it ideal for brunch or a hearty lunch.

With a flaky crust that's both sturdy and delicate, this quiche bakes up with a golden-brown top and tender filling—no soggy bottoms here. The spinach wilts just enough to release its flavor without losing texture, while the eggs set into a velvety custard that holds together beautifully.

It's the kind of dish that feels indulgent yet balanced, perfect for feeding a crowd or enjoying as a solo meal.

Ready in about 50 minutes, this quiche requires minimal prep but delivers restaurant-quality results. The filling comes together in one bowl, and the crust is simple to assemble, making it a foolproof recipe even for beginners.

Serve it warm with a side salad or crusty bread for the full experience.

Ingredients for bacon swiss cheese quiche

Six ingredients for the crust, seven for the filling—simple buttery layers deliver restaurant-quality quiche.

The crust starts with cold butter and ice water—never skip this. Kirkland Signature flour from Costco gives the best texture, but any all-purpose works. For the butter, Land O'Lakes unsalted is my go-to since it's consistently cold from the store. Preheat your oven to 375°F before mixing anything—cold ingredients are key to that flaky result. The Swiss cheese? Huber brand melts the best without turning rubbery, but any good-quality shredded will do. Just don't use the pre-shredded kind with anti-caking agents—it burns easily.

No heavy cream? Full-fat Greek yogurt thinned with milk works in a pinch, though the texture won't be identical. Fresh spinach is ideal, but frozen chopped spinach thawed and drained saves time—just squeeze out all the moisture. The bacon should be cooked until crispy, then crumbled while still warm so it releases more fat into the filling. Applegate or Oscar Mayer nitrite-free bacon has the best flavor without overpowering. For the nutmeg, Penzeys brand is worth the splurge—it's the only way to get freshly grated. If you're out, half the amount of ground nutmeg will work, but it won't have the same depth.

The crust dough keeps 2 hours wrapped in plastic in the fridge, or you can freeze it for up to 3 days before baking. For the filling, mix everything in one bowl—it's ready when it looks like thick custard. Assemble the quiche and refrigerate 30 minutes before baking to prevent a soggy crust. Leftovers reheat beautifully—cover with foil and warm at 350°F for 10-12 minutes. Store filling components separately in the fridge for up to 2 days before assembling.

Step-by-step instructions for bacon, Swiss cheese, and spinach quiche

Mastering this quiche comes down to two key techniques: a perfectly flaky crust and a creamy, well-set filling.

In a large bowl, combine the 2.5 cups all-purpose flour with the 1.5 tsp salt and 0.25 tsp nutmeg. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for achieving that signature flaky texture.

Gradually add the 0.5 cup ice water, one tablespoon at a time, mixing just until the dough begins to come together. Be careful not to overwork it—handle only until the dough forms a rough ball. The cold butter and ice water work together to create steam pockets during baking, which is what gives you that perfect flakiness.

Turn the dough onto a lightly floured surface and gently shape it into a disk about 12 inches in diameter. Roll it out to fit a 9-inch pie dish, keeping the edges slightly thicker than the center. Transfer the crust to your pie dish and press it gently into the bottom and up the sides.

Preheat your oven to 375°F. Line the crust with parchment paper and fill it with pie weights or dried beans. Bake for 15 minutes until the edges begin to set. Remove the weights and bake for another 5 minutes until the crust is lightly golden. This pre-baking step prevents a soggy bottom and ensures your crust holds its shape when the filling goes in.

In a large bowl, whisk together the 4 whole large eggs, 1 cup heavy whipping cream, 1 cup whole milk, 0.5 tsp ground black pepper, and 1.5 tsp salt. The mixture should be smooth and well combined. In a separate bowl, combine the 2 cups shredded Swiss cheese, 8 oz cooked bacon, 5 oz chopped fresh spinach, and 2 cloves minced garlic. Gently mix these ingredients together, being careful not to overwork the spinach.

Here's where the magic happens: fold the cheese mixture into the egg mixture until just combined. You want to maintain some texture in the spinach and bacon while still distributing them evenly throughout the custard. The Swiss cheese should melt beautifully during baking, creating those signature gooey pockets.

Carefully pour the filling mixture into the pre-baked crust. Sprinkle any remaining shredded Swiss cheese on top for an extra melty layer. Place the quiche on a baking sheet to catch any potential drips and transfer it to the oven. Bake at 350°F for 40-45 minutes, until the center is just set and the edges are golden brown.

To check doneness, insert a knife near the center—it should come out clean but slightly moist. The quiche will continue to set as it cools, so don't worry if it looks slightly underdone at this point. Let it rest for 10-15 minutes before slicing. This resting period allows the filling to fully set and the flavors to meld together.

Slice the quiche into 6 equal wedges, serving immediately or allowing it to cool slightly for easier handling. The crust should be golden and flaky, the filling creamy yet set, and the Swiss cheese should be melted throughout with visible pockets of gooey goodness. Each bite should deliver a perfect balance of smoky bacon, earthy spinach, and rich, nutmeg-infused Swiss cheese.

For best results, serve at room temperature. The quiche keeps well in the refrigerator for up to 3 days, though I find it's best enjoyed fresh. Pair with a simple green salad and crusty bread for a complete meal that's sure to impress.

Dietary considerations for this dish

Gluten-Free Adaptation

For a gluten-free version, swap the all-purpose flour crust for a 1:1 gluten-free flour blend like Bob's Red Mill or King Arthur. I recommend adding 1 extra tablespoon of cold butter to compensate for the blend's lower fat absorption.

Press the crust firmly into the pie dish and blind-bake for 5 extra minutes—gluten-free crusts need longer to set. The filling remains unchanged, so you'll still get that rich Swiss-cheese and bacon flavor without the gluten. 🌾

Dairy-Free Options

To make this quiche dairy-free, replace the Swiss cheese with 2 cups of dairy-free shredded cheddar (like Violife or Daiya) and use unsweetened almond milk instead of whole milk. For the heavy cream, I recommend full-fat coconut cream—it adds richness without dairy.

The crust stays the same, but the filling will have a slightly lighter texture. Trust me, it still tastes amazing with these swaps!

Lower-Carb Version

Cut carbs significantly by using a cauliflower crust (pre-made or homemade) and reducing the filling's dairy. Replace the heavy cream with unsweetened almond milk and the Swiss cheese with 2 cups of crumbled feta (for a tangy twist).

Keep the bacon and spinach as-is—they add flavor without many carbs. This version clocks in at around 8 net carbs per serving, perfect for keto diets. 🥦

Vegetarian Swap

Skip the bacon and use smoked paprika (½ tsp) in the egg mixture for depth. Add ½ cup of sautéed mushrooms and ¼ cup of sun-dried tomatoes to the filling for umami.

The Swiss cheese remains the star, but this vegetarian version still delivers that satisfying, savory bite. It’s a great way to keep the quiche’s signature richness without meat. 🍄

Nut-Free Considerations

This recipe is naturally nut-free, but always double-check your ingredients. The crust uses only flour, butter, and water, while the filling contains eggs, dairy, and bacon.

If you're avoiding nuts elsewhere in your meal, pair this quiche with a fruit salad or roasted vegetable medley to keep everything safe and delicious. No worries here—this dish is already nut-free by design! 🍎
