Ingredients You’ll Need
The magic of this Cheese & Caramelized Onion Quiche Recipe lies in the simplicity and quality of its ingredients. Each one adds a special note — from the silky caramelized onions that provide natural sweetness, to the flaky phyllo crust that gives a delightful crunch, and the creamy blend of eggs, milk, and cheese that pulls everything together in a creamy, dreamy filling.
- 1 large onion (chopped, about 1½ cups): The star for those deep, sweet caramelized flavors that make this quiche unforgettable.
- 1 tablespoon unsalted butter or ghee: For perfectly soft and golden onions with a hint of richness.
- 1 tablespoon olive oil: Balances out the butter and helps cook the onions slowly and evenly.
- 1/4 teaspoon kosher salt: Enhances the natural flavors, especially in the onions and filling.
- 8 sheets phyllo dough: This thin pastry creates a crisp, flaky crust with beautiful layers; remember to keep it covered to maintain moisture.
- ¼ cup melted ghee or clarified butter: Brushing the phyllo ensures a crispy, golden crust that you’ll love biting into.
- 6 large eggs: The essential ingredient that sets the quiche filling, creating that classic, creamy texture.
- ¾ cup whole milk: Adds smoothness and richness to the custard without overpowering it.
- ½ cup heavy cream: For that indulgent creaminess that elevates every forkful.
- ½ cup crème fraîche: Offers a subtle tang and lusciousness that perfectly balances the sweetness of the onions.
- ½ teaspoon kosher salt: To season the filling just right.
- ¼ teaspoon freshly ground black pepper: Adds a gentle kick that brings the flavors alive.
- ¼ teaspoon freshly ground nutmeg: A warm spice that gives the filling subtle complexity and depth.
- 4½ oz cheese of your choice (shredded, about 1½ cups): Melts beautifully into the filling; choose a cheese you love like Gruyère, sharp cheddar, or a blend for strong flavor.
How to Make Cheese & Caramelized Onion Quiche Recipe
Step 1: Caramelize the Onions
Start by melting the butter and olive oil in a large skillet over medium-low heat. Toss in the chopped onions with a pinch of kosher salt and patiently cook them low and slow for 40 to 50 minutes. It’s worth the wait for those golden, tender onions bursting with sweet flavor. If you rush this, you’ll miss the magic, so keep the heat low and stir occasionally until they reach that perfect light brown caramelization.
Step 2: Prepare Your Oven and Phyllo Crust
Position your oven rack low, about the bottom third, and preheat to 375°F with a baking stone or sheet inside to get nice and hot. Lightly brush melted ghee onto a deep-dish 10-inch pie pan, and gently layer in one phyllo sheet at a time, brushing each with more melted ghee. Rotate the sheets as you layer to ensure the crust is evenly covered on all sides. Keep your phyllo covered with a damp towel while working so it doesn’t dry out, then fold the edges neatly and brush with more ghee to set the crust up for a beautiful crisp bake.
Step 3: Blind Bake the Phyllo Crust
Place a light weight – like a small pie pan or parchment with pie weights – inside your crust to keep it from puffing up, then bake on the preheated stone for about 10 minutes, until the edges are just starting to turn golden. Remove the weight and bake a few minutes longer to dry out the bottom, ensuring your quiche stays crisp and flaky to the last bite.
Step 4: Mix the Creamy Filling
Lower the oven temperature to 350°F. In a blender or large bowl, combine the eggs, whole milk, heavy cream, and crème fraîche along with salt, pepper, and nutmeg. Blend or whisk gently until everything is smooth and just combined. This rich custard-like mixture is the heart of your quiche, wonderfully creamy and full of flavor.
Step 5: Assemble and Bake the Quiche
Scatter your caramelized onions evenly across the par-baked phyllo crust, then sprinkle about two-thirds of the shredded cheese over the top. Slowly pour the egg mixture in, followed by the remaining cheese. Bake for 45 to 55 minutes until the edges are puffed and golden, and the center is just set but slightly jiggly. If the crust browns too fast, shield the edges with foil to keep everything perfect.
Step 6: Cool and Set
Remove your quiche to a wire rack and let it cool to room temperature completely, which takes about 1 to 2 hours. For the best results, cover and refrigerate it for a few hours or overnight to allow the filling to fully set. This step makes slicing neat and the flavors even more harmonious.
Step 7: Reheat Before Serving
When ready to enjoy, warm individual slices on a baking sheet at 350°F for 5 to 10 minutes until heated through and the crust regains its crispness. This quiche is just as delightful served fresh or warmed up again, making it wonderfully versatile.

Garnishes
A sprinkle of fresh chopped herbs like thyme, chives, or parsley makes a perfect finishing touch, adding a pop of vibrant color and a fresh contrast to the rich filling. A light drizzle of good olive oil or a few cracks of fresh black pepper can also elevate every bite.
Side Dishes
This quiche pairs beautifully with crisp green salads tossed with lemon vinaigrette or a simple arugula salad to cut through the richness. For heartier options, roasted seasonal vegetables or a bowl of soup complement it perfectly for a complete, satisfying meal.
Creative Ways to Present
Consider serving this Cheese & Caramelized Onion Quiche Recipe as individual mini-quiches in muffin tins for a charming brunch spread or picnic treat. Another fun idea is to slice it into wedges and serve it alongside a cheese platter with olives, nuts, and fruits for an elegant appetizer display.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your quiche tightly with plastic wrap or keep it in an airtight container and store it in the refrigerator. It will stay fresh for up to 3 days, making it an ideal make-ahead dish for busy weeks or unexpected guests.
Freezing
Cheese & Caramelized Onion Quiche Recipe freezes well if wrapped securely. Slice it into portions and freeze them individually by wrapping each piece tightly in plastic and foil before placing in a freezer bag. Frozen quiche can last up to 2 months, perfect for having wholesome meals ready when you need.
Reheating
To bring frozen or refrigerated quiche back to life, heat slices in a 350°F oven for 10-15 minutes. This method keeps the crust crisp and the filling creamy, avoiding sogginess that microwave reheating can cause.
FAQs
Can I use a different type of crust instead of phyllo?
Absolutely! While phyllo dough offers a wonderfully flaky, crisp texture, you can substitute with traditional pie pastry or even a savory tart crust based on what you have or prefer. Each gives a slightly different experience but all are delicious.
What cheeses work best in this quiche?
Gruyère, sharp white cheddar, fontina, or even a mix of your favorites are excellent choices. The key is a cheese that melts well and complements the sweetness of the caramelized onions.
Can I make the caramelized onions ahead of time?
Definitely! In fact, caramelized onions are perfect make-ahead components. Simply refrigerate them in an airtight container for up to 3 days, and they’ll still taste beautifully sweet and tender when it’s time to bake.
Is this recipe suitable for a crowd?
Yes, the Cheese & Caramelized Onion Quiche Recipe serves about 8 people, making it ideal for brunches, family dinners, or potlucks. Plus, it’s easy to double or halve depending on your needs.
How do I know when the quiche is done?
Look for golden, puffed edges and a filling that’s set but still slightly jiggly in the center. A knife inserted near the middle should come out mostly clean. If the crust edges brown too quickly, use foil to protect them while the rest finishes baking.

Ingredients
Caramelized Onions
- 1 large onion, chopped (about 1½ cups chopped)
- 1 tablespoon unsalted butter or ghee
- 1 tablespoon olive oil
- ¼ teaspoon kosher salt
Crust
- 8 sheets phyllo dough (9-by-13-inch sheets; if using 13-by-18-inch sheets, cut in half)
- ¼ cup melted ghee or clarified butter
Filling
- 6 large eggs
- ¾ cup whole milk
- ½ cup heavy cream
- ½ cup crème fraîche
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon freshly ground nutmeg
- 4½ oz cheese of choice, shredded (about 1½ cups shredded)
Instructions
- Caramelize Onions: Melt butter and olive oil in a large skillet over medium-low heat. Add chopped onions and cook, stirring occasionally, until the onions turn light golden brown, approximately 40 to 50 minutes. Adjust heat if onions brown too quickly. Once caramelized, set aside or refrigerate until ready to use.
- Preheat Oven and Prepare Baking Surface: Place an oven rack in the bottom third of the oven. Put a baking stone or metal baking sheet on the rack and preheat the oven to 375°F (190°C).
- Prepare Phyllo Crust: Lightly brush a 10-inch deep dish pie pan with melted ghee. Drape one sheet of phyllo dough into the pan and brush lightly with melted ghee, focusing on sides and edges, and a thin layer on the bottom. Keep remaining phyllo sheets covered with plastic wrap and a damp towel to prevent drying.
- Layer Phyllo Sheets: Repeat with remaining sheets, rotating each sheet’s angle to ensure even coverage over the entire pie pan.
- Finish Crust Edges: Brush the last phyllo sheet with ghee and gently fold over the edges so they align with the top rim of the pan. Brush folded edges again with ghee.
- Blind Bake Crust: Place a light weight, such as a 7-inch aluminum pie pan or pie weights, on the crust bottom. Bake on the preheated stone or sheet for 10 minutes until edges start to color. Remove weights and bake for an additional 2-3 minutes to dry the bottom. Let cool slightly.
- Reduce Oven Temperature: Lower the oven temperature to 350°F (175°C).
- Prepare Filling: In a blender, combine eggs, whole milk, heavy cream, and crème fraîche. Blend on low speed until smooth. Stir in salt, pepper, and nutmeg. Alternatively, whisk by hand until fully blended.
- Assemble Quiche: Spread caramelized onions evenly in the par-baked crust, then sprinkle about 1¼ cups of shredded cheese over the onions. Gently pour the egg mixture on top, then scatter the remaining cheese evenly over the filling.
- Bake Quiche: Bake for 45 to 55 minutes until the edges are browned, puffed, and the center is just slightly jiggly. Check at 30 to 40 minutes; if crust edges brown too fast, loosely cover with foil.
- Cool and Set: Remove the quiche from oven and place on a wire rack to cool completely to room temperature, about 1 to 2 hours. For best results, refrigerate covered for several hours or overnight to fully set before slicing.
- Reheat Before Serving: To serve warm, place slices on a baking sheet and bake at 350°F (175°C) for 5 to 10 minutes until heated through and crust is crispy.
Notes
- Caramelized onions can be prepared up to several days in advance and refrigerated.
- Keep phyllo dough covered with plastic wrap and a damp towel while working to prevent it from drying out.
- Use a light weight for blind baking, such as a smaller pie pan, parchment with weights, or pie chains to prevent crust bubbling.
- If the crust edges brown too quickly during baking, cover them with foil to avoid burning.
- Allowing the quiche to set in the refrigerator before slicing improves texture and sliceability.
- Feel free to use your preferred cheese such as Gruyère, cheddar, or Swiss for variation.
