Ingredients You’ll Need

You don’t need a laundry list for a great quiche—the beauty of Secret Ingredient Ham & Swiss Quiche is how each ingredient shines and adds its own magic. From the savory punch of ham to the creamy richness of eggs and cream, every component brings something special to the party.

Pie Crust: A 9-inch deep dish frozen or refrigerated pie shell saves time and creates that classic, flaky base for your quiche.
Eggs: Six large eggs form the foundation of the custard, making the filling fluffy and rich.
Heavy Cream: For decadent creaminess, heavy cream can’t be beat—it’s what gives the quiche its signature, velvety texture.
Mayonnaise (the secret ingredient!): Just two tablespoons provide subtle tang and mellow creaminess—don’t skip it!
Dried Mustard Powder: Adds a gentle, earthy bite that lifts the whole dish.
Worcestershire Sauce: A splash brings an extra dimension of savory flavor that’s hard to pinpoint, but you’ll miss it if it’s gone.
Salt: Just enough to intensify all those complex flavors.
Coarse Ground Black Pepper: For that signature touch of warmth and spice.
Red Pepper Flakes: A pinch wakes up your palate with a hint of heat.
Diced Ham: 1 to 1.5 cups of salty, meaty ham infuses the whole quiche with heartiness and depth.
Shredded Swiss Cheese: Two cups add nuttiness and melt beautifully into the custard.
Chopped Green Onion: Brightens every bite with freshness and a pop of color.

How to Make Secret Ingredient Ham & Swiss Quiche

Step 1: Blind Bake the Crust

Start by preheating your oven to 350° Fahrenheit. Take your pie shell out of the freezer (or fridge) and let it sit for a few minutes so it’s easy to handle. Using a fork, poke holes in the bottom—this is key to let steam escape and avoid a soggy base. Blind bake the crust for 10 minutes; it should look slightly golden and set, but not fully browned. This step ensures the crust stays flaky even after you add the creamy custard.

Step 2: Prep the Filling

While the crust does its thing in the oven, gather and prep your ingredients. Dice the ham, shred the Swiss cheese, and chop the green onion so everything is ready to layer. In a large mixing bowl, whisk together eggs, heavy cream, mayo (the secret ingredient!), dried mustard powder, Worcestershire sauce, salt, black pepper, and pepper flakes. Don’t rush this step—whisk until the cream and eggs look nice and frothy. This extra air translates into a luxuriously light quiche later!

Step 3: Assemble the Quiche

Once your crust is blind baked, it’s time to build the layers of flavor. Scatter the diced ham evenly across the bottom of the crust, followed by the shredded Swiss cheese, then toss over the chopped green onion. Pour the egg and cream mixture gently over the top. Be careful not to overfill the crust—leave a bit of space so it doesn’t overflow as it bakes. Tent the quiche loosely with foil to prevent the top from browning too fast, and pop it into your preheated oven for 30 minutes.

Step 4: Bake to Perfection

After the first half hour, carefully remove the foil from the top of your Secret Ingredient Ham & Swiss Quiche so the crown can take on a gorgeous golden color. Continue baking for another 20 to 25 minutes. You’re aiming for a quiche that’s just set—look for a barely-there jiggle in the center. This guarantees creamy slices that hold together perfectly. Remove the quiche from the oven and let it cool for about 15 minutes; it finishes setting during this time and is easier to slice.

Step 5: Finish and Serve

Before serving, top with some snipped fresh chives if you have them—they add a brilliant burst of flavor and stunning color. Serve warm, at room temperature, or even cold straight from the fridge. Each slice showcases those beautiful layers, and the aroma is pure comfort.

How to Serve Secret Ingredient Ham & Swiss Quiche

Garnishes

Add a sprinkle of freshly chopped chives or extra green onion on top just before serving for extra flair. Cracked black pepper or even a few shavings of Swiss cheese can take your Secret Ingredient Ham & Swiss Quiche from casual to celebration-worthy in seconds.

Side Dishes

Pair your quiche with a crisp green salad tossed in lemony vinaigrette, or a bowl of fresh seasonal fruit for a bright contrast to the rich custard. Roasted asparagus or simply dressed baby arugula are also fabulous company for Secret Ingredient Ham & Swiss Quiche, making your meal both satisfying and well-rounded.

Make Ahead and Storage

Storing Leftovers

To save leftovers, let your quiche cool completely, then cover tightly with foil or plastic wrap and keep in the fridge. It will remain delicious for up to 4 days and makes an unbeatable quick breakfast or late-night snack.

Freezing

Secret Ingredient Ham & Swiss Quiche freezes beautifully. For best results, wrap slices individually in plastic wrap, then place in a freezer-safe bag or container. It will keep well for up to two months—just thaw overnight in the fridge when you’re ready to enjoy again.

Reheating

Warm individual slices of quiche in the oven at 325° Fahrenheit for 10-15 minutes, or microwave on medium power in short bursts until heated through. The key is not to rush—gentle reheating preserves that creamy, custardy center and flaky crust.

FAQs

Can I use a different kind of cheese?

Absolutely! While Swiss offers a nutty, melty quality that’s classic in quiche, Gruyère, sharp cheddar, or even creamy fontina are all fantastic choices to put your personal spin on Secret Ingredient Ham & Swiss Quiche.

What if I don’t have dried mustard powder?

No problem—swap in a teaspoon of Dijon mustard. It’ll give you a similar tangy pop and enhance the flavor of the ham and cheese in the quiche beautifully.

Can I make Secret Ingredient Ham & Swiss Quiche ahead of time?

Yes! You can fully bake the quiche the day before, let it cool, and then store it in the fridge. It tastes amazing reheated or even served cold, so it’s perfect for prepping ahead for holidays or gatherings.

How do I know my quiche is done baking?

Give the pan a gentle shake; if the middle just barely jiggles and the edges look set, it’s ready. Overbaking can cause a rubbery texture, so start checking in the last 5 minutes of baking for perfect results.
