The first time I ate quiche Lorraine in a tiny bakery off a cobbled lane in Lyon, I understood why the French guard their egg-and-cream ratios like family recipes. This Quick Spinach Quiche borrows that same custardy confidence but folds in a mountain of spinach and nutty Gruyere so a single slice feels like a full, honest meal.

I built this version for the mornings when guests arrive in forty minutes and the fridge holds little more than eggs, a bag of greens, and a hopeful block of cheese. A store-bought crust keeps it fast, while a quick saute and a patient whisk keep it tasting slow and deliberate.
Whether you serve it warm from the oven or at room temperature on a picnic blanket, this quiche travels well, slices cleanly, and tastes like something you planned all week.
Why You'll Love This Recipe
About the Ingredients
1 refrigerated 9-inch pie crust (about 8 oz / 225 g), or 1 sheet frozen puff pastry, thawed
A deep-dish frozen crust works if you press it into your own pan. For a gluten-free swap, use a gluten-free refrigerated pie crust and blind-bake it 2 minutes longer.
2 tablespoons (28 g) unsalted butter
Salted butter works; just skip the added salt in the custard. Olive oil can replace it for a dairy-light version.
1 medium yellow onion (about 1 cup / 150 g), thinly sliced
Sweet onion or two large shallots are lovely substitutes. Buy onions that feel heavy and firm with dry, papery skins.
8 cups (about 240 g) fresh baby spinach, packed
Frozen spinach works too: thaw 10 oz (280 g), then squeeze it bone-dry in a clean towel. Baby spinach is milder than mature leaves, so buy the baby kind if you can.
3 large eggs
Use room-temperature eggs for a smoother custard. For a lighter set, swap one egg for two egg whites.
1 cup (240 ml) whole milk
Half-and-half or a 50/50 mix of milk and heavy cream gives a richer, denser slice. Oat milk makes a decent dairy-free stand-in.
4 oz (115 g) Gruyere cheese, shredded (about 1 cup)
Swiss, Jarlsberg, or sharp white cheddar all melt beautifully here. Buy a block and shred it yourself; pre-shredded cheese is coated and melts less smoothly.
1/4 teaspoon freshly grated nutmeg
A whole nutmeg grated on a Microplane beats pre-ground by a mile. Ground mace is the classic substitute.
1/2 teaspoon kosher salt
Diamond Crystal and Morton differ in saltiness, so taste your custard before pouring. Fine sea salt works in the same amount.
1/4 teaspoon freshly ground black pepper
White pepper keeps the custard pristine if you dislike black flecks. Add a pinch of cayenne for gentle warmth.
Tips & Tricks
Squeeze the spinach dry
Watery greens are the number one cause of a soggy quiche, so press the wilted spinach in a colander with the back of a spoon until no more liquid drips.
Blind-bake the crust first
Ten minutes at 375 F (190 C) with parchment and pie weights keeps the bottom crisp instead of doughy.
Pull it while the center still jiggles
The custard keeps cooking as it rests, so a slightly wobbly center means a silky, never rubbery slice.
Cool before slicing
Give the quiche 10 to 15 minutes so the custard finishes setting and the slices hold their shape.
Pro Tips
Step-by-Step Instructions
1. Heat the Oven
Preheat the oven to 375 F (190 C) and set a rack in the lower-middle position. Place your pie crust on a rimmed baking sheet so it is ready to slide in.
2. Blind-Bake the Crust
Line the crust with parchment and fill with pie weights or dried beans. Bake 10 minutes, then lift out the weights and parchment and bake 3 more minutes until the surface looks dry and barely golden.
3. Wilt the Spinach
Melt the butter in a large skillet over medium heat, add the onion, and cook 7 to 8 minutes until soft and golden. Add the spinach in handfuls, stirring until just wilted, about 3 minutes, then transfer to a colander and press out all excess liquid.
4. Whisk the Custard
In a large bowl, whisk the eggs, milk, salt, pepper, and nutmeg until completely smooth with no streaks of white. Stir in about three-quarters of the Gruyere.
5. Fill the Shell
Scatter the drained spinach mixture evenly across the warm crust, then pour the custard over the top. Sprinkle the remaining Gruyere across the surface for a golden, cheesy lid.
6. Bake Until Set
Bake at 375 F (190 C) for 30 to 35 minutes, until the edges are puffed and golden brown, the center is set with a faint jiggle, and an instant-read thermometer in the middle reads 160 F (71 C).
7. Cool and Slice
Transfer to a wire rack and cool 10 to 15 minutes before slicing. Serve warm or at room temperature.
Delicious Variations
Mushroom and Thyme Quiche
Saute 8 oz (225 g) sliced cremini mushrooms with the onion and add 1 teaspoon fresh thyme for an earthy, deeply savory version.
Ham and Cheddar Quiche
Fold 1 cup diced cooked ham and swap the Gruyere for sharp cheddar, plus a pinch of dry mustard in the custard.
Mediterranean Quiche
Add 1/2 cup crumbled feta, 1/3 cup chopped sun-dried tomatoes, and 2 tablespoons chopped kalamata olives for a briny, bright twist.
How to Store Quick Spinach Quiche
Refrigerator
Cool completely, cover tightly, and refrigerate up to 4 days. Press plastic wrap directly onto the surface to keep the custard from drying out.
Freezer
Wrap individual slices tightly in plastic and foil and freeze up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat slices at 325 F (165 C) for 10 to 12 minutes, or microwave single slices 45 to 60 seconds until just warm.
Frequently Asked Questions
Q: How do I keep my spinach quiche from getting soggy?
Squeeze every drop of water out of the cooked spinach and blind-bake the crust before filling it. Both steps stop the custard from pooling and turning the bottom crust doughy.
Q: Can I make spinach quiche ahead of time?
Yes, bake it up to 2 days ahead, cool completely, then refrigerate covered. It also freezes well for up to 2 months, so you can bake two and stash one.
Q: What is the best cheese for spinach quiche?
Gruyere is the classic choice for its nutty, melty character, but Swiss, Jarlsberg, fontina, or sharp cheddar all work. Avoid very soft cheeses like ricotta unless you are blending them into the custard.
Q: How do I know when quiche is fully baked?
The edges should be puffed and golden and the center should jiggle only slightly when you nudge the pan. An instant-read thermometer in the center should read 160 F (71 C).
Q: Can I use frozen spinach instead of fresh?
Absolutely, and it is actually faster. Thaw 10 oz (280 g) of frozen spinach, then squeeze it dry in a clean kitchen towel before folding it in.
