Spinach and Gruyere Quiche with Smoked Bacon - A Cozy, Savory Brunch Favorite

Prep Time 20 minutes minutes

Cook Time 45 minutes minutes

Total Time 1 hour hour 5 minutes minutes

Servings 8 servings

Ingredients

• 1 9-inch pie crust (store-bought or homemade), chilled
• 6 slices smoked bacon, chopped
• 1 tablespoon unsalted butter (optional, as needed for sautéing)
• 1 small yellow onion, finely diced
• 2 cups fresh spinach, roughly chopped (or 1 cup thawed frozen spinach, well-drained)
• 1 cup Gruyere cheese, freshly grated
• 4 large eggs
• 1 cup whole milk
• 1/2 cup heavy cream
• 1 teaspoon Dijon mustard
• 1/2 teaspoon kosher salt (adjust to taste)
• 1/4 teaspoon freshly ground black pepper
• 1/8 teaspoon ground nutmeg (optional but lovely with Gruyere)

Instructions

• Preheat and prep: Heat the oven to 375°F (190°C). If your pie crust is not par-baked, line it with parchment and fill with pie weights or dried beans. Bake for 12–15 minutes until lightly set. Remove weights and parchment, and let cool slightly.
• Cook the bacon: In a skillet over medium heat, cook the chopped smoked bacon until crisp, 6–8 minutes. Transfer to a paper towel-lined plate. Pour off most of the bacon fat, leaving about 1 tablespoon in the pan.
• Soften the onion: Add the diced onion to the skillet. Sauté over medium heat until translucent and lightly golden, 4–6 minutes. If the pan looks dry, add a small pat of butter.
• Wilt the spinach: Stir in the chopped fresh spinach and cook until just wilted, 1–2 minutes. If using frozen spinach, add it now and cook until any excess moisture evaporates. Set the mixture aside to cool slightly.
• Whisk the custard: In a bowl, whisk together the eggs, milk, cream, Dijon mustard, salt, pepper, and nutmeg until smooth and well combined.
• Assemble the filling: Scatter half the Gruyere over the bottom of the par-baked crust. Top with the onion-spinach mixture and the crisp bacon. Sprinkle over the remaining Gruyere.
• Pour the custard: Slowly pour the egg mixture into the crust, letting it seep into the filling evenly. Tap the pie dish gently to release any air bubbles.
• Bake: Place the quiche on a baking sheet to catch any drips. Bake for 30–40 minutes, until the center is just set with a slight wobble and the top is lightly golden.
• Rest and serve: Let the quiche rest for at least 15–20 minutes before slicing. It cuts cleaner and the texture settles. Serve warm or at room temperature.

• Balanced flavor: The nuttiness of Gruyere and smokiness of bacon play beautifully with mild, earthy spinach.
• Creamy yet sturdy texture: The custard is soft and silky, but slices cleanly and holds up well.
• Make-ahead friendly: Bake it the day before and reheat for a stress-free brunch.
• Simple ingredients: You’ll find everything at a regular grocery store—no specialty items required.
• Versatile: Works with store-bought pie crust or homemade, and it’s easy to tweak to your taste.

Common Mistakes to Avoid

• Skipping the par-bake: Without it, the crust can turn soggy. A quick par-bake keeps it crisp.
• Adding wet spinach: Excess moisture can water down the custard.Squeeze or cook off the liquid first.
• Overbaking: The custard should have a slight wobble in the center. It firms up as it cools.
• Using pre-shredded cheese only: Pre-shredded cheese often has anti-caking agents. Freshly grated Gruyere melts better and tastes richer.
• Pouring in all the bacon fat: A little adds flavor, but too much can make the quiche greasy.

Recipe Variations

• Mushroom and Leek: Swap onion for sliced leeks and add sautéed mushrooms for an earthy twist.
• Ham and Swiss: Replace bacon with chopped ham and Gruyere with Swiss for a classic combo.
• Spinach and Feta: Skip the bacon, add feta and a pinch of dried oregano for a Mediterranean feel.
• Roasted Red Pepper and Goat Cheese: Fold in chopped roasted peppers and dollops of goat cheese.
• Gluten-Free: Use a gluten-free crust or bake without crust in a greased pie dish (reduce baking time slightly).
• Lighter Option: Use half-and-half instead of milk and cream, and reduce cheese by 1/4 cup.

FAQ

Do I have to blind-bake the crust?

Yes.

Blind-baking (par-baking) helps the crust set first so it doesn’t soak up the custard and become soggy. It only takes about 12–15 minutes and makes a big difference.

Can I use a different cheese?

Absolutely. Swiss, Comté, or a mild cheddar work well.

Choose a melting cheese with good flavor, and grate it fresh for best results.

What milk and cream ratio works best?

A mix of 1 cup whole milk and 1/2 cup heavy cream gives a creamy texture without being too rich. You can use all half-and-half if that’s what you have.

How do I know when the quiche is done?

Look for a lightly golden top and a center that jiggles slightly when you nudge the pan. If it’s sloshing, keep baking; if it’s rigid, it’s overdone.

Can I make it ahead?

Yes.

Bake it, cool completely, then cover and refrigerate. Reheat in a 325°F (165°C) oven until warmed through. You can also assemble the filling and crust components the day before and bake fresh.

What should I serve with it?

A simple green salad with a lemony vinaigrette, sliced tomatoes, or fruit salad pairs nicely.

For brunch, add roasted potatoes or a light soup.

Can I use frozen spinach?

Yes. Thaw completely, then squeeze out as much moisture as possible. Measure about 1 cup after draining.

Why is my quiche watery?

Usually it’s from excess moisture in the vegetables or under-baked custard.

Make sure to cook off liquids from spinach and bake until just set.
