Kale and Onion Quiche: A Savory Slice of Sunshine

The scent of a warm quiche baking in the oven has a special place in my heart. It takes me back to weekend mornings spent at my grandmother’s farmhouse. She’d always have a quiche ready, filled with whatever vegetables were in season – zucchini, tomatoes, and, of course, plenty of onions. The slightly caramelized onions mixed with the creamy custard and flaky crust was pure comfort food, and I can still almost feel the warmth of the sun streaming through the kitchen window as we shared slices around her worn wooden table. This kale and onion quiche is my take on that classic, a little heartier and packed with nutrients but still capturing that same feeling of simple, delicious contentment.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 45-55 minutes
Total Time: 1 hour 5 minutes – 1 hour 15 minutes
Servings: 6
Yield: 1 pie
Dietary Type: Vegetarian

Ingredients

1 prepared 9 inch pie shell

For the Filling:

3 eggs
¾ cup half-and-half
¾ cup milk
½ teaspoon salt
½ teaspoon red pepper flakes (optional)
Black pepper to taste
1 tablespoon vegetable oil
1 tablespoon butter
5 green onions, minced
3 garlic cloves, chopped
2 cups kale, chopped
½ cup cheddar cheese, grated

Equipment Needed

9-inch pie dish
Aluminum foil
Dried beans or pie weights
Large bowl
Whisk
Skillet
Measuring cups and spoons

Instructions

Preheat your oven to 425-degrees F (220-degrees C). This initial high heat helps to set the crust and prevent it from becoming soggy.
Prepare the crust for blind baking. Tear off a piece of foil large enough to fit inside of the pie crust. Gently press the foil into the pie crust, ensuring it covers the bottom and sides completely. Fill the foil-lined crust with dried beans or pie weights. This will prevent the crust from puffing up during baking.
Bake the crust for 10-15 minutes. This partial baking is crucial for a crisp crust.
Remove the crust from the oven. Carefully discard the foil and dried beans (you can save the beans for future blind baking). Set the crust aside to cool slightly while you prepare the filling.
In a large bowl, whisk together the eggs, half-and-half, milk, salt, red pepper flakes (if using), and a generous grind of black pepper. Whisk until the ingredients are well combined and the mixture is slightly frothy. Set aside.
Prepare the kale and onion mixture. In a skillet, heat the vegetable oil and butter over medium-high heat. The combination of oil and butter adds flavor and helps prevent burning.
Add the minced green onions and chopped garlic to the skillet. Cook, stirring frequently, until the onions are softened and translucent and the garlic is fragrant, about 3-5 minutes. Be careful not to burn the garlic.
Add the chopped kale to the skillet. Cook, stirring occasionally, until the kale is wilted and tender, about 5 minutes. The kale should reduce in volume significantly.
Spoon the kale and onion mixture evenly into the partially baked pie crust.
Sprinkle the grated cheddar cheese evenly over the vegetables in the crust.
Gently pour the egg/milk mixture over the vegetables and cheese in the crust. Be careful not to overfill the crust.
Bake the quiche in the preheated oven for 30-40 minutes, or until the filling is set and the crust is golden brown. The quiche is done when the center is no longer jiggly and a knife inserted into the center comes out clean.
Let the quiche cool slightly before slicing and serving. This allows the filling to set further, making it easier to cut.

Expert Tips & Tricks

Prevent a Soggy Bottom: Blind baking the crust is essential for preventing a soggy bottom. Also, make sure the kale mixture isn’t too wet before adding it to the crust. You can squeeze out any excess moisture with a paper towel.
Customize Your Cheese: Feel free to experiment with different cheeses. Gruyere, Swiss, or even a sharp provolone would all work well in this quiche.
Spice It Up: For extra heat, add a pinch of cayenne pepper to the egg mixture along with the red pepper flakes.
Make Ahead: You can prepare the kale and onion mixture a day ahead and store it in the refrigerator. This will save you time on the day you plan to bake the quiche.
Even Baking: If your crust is browning too quickly, you can loosely cover the edges with foil during the last 15 minutes of baking.

Serving & Storage Suggestions

Serve the kale and onion quiche warm or at room temperature. It’s delicious on its own or as part of a brunch spread with a side salad.

To store leftovers, allow the quiche to cool completely before wrapping it tightly in plastic wrap or placing it in an airtight container. It will keep in the refrigerator for up to 3 days.

To reheat, you can warm individual slices in the microwave or bake the entire quiche in a preheated oven at 350-degrees F (175-degrees C) until heated through.

Freezing is possible, but the texture may change slightly. Wrap tightly in plastic wrap and then foil. Reheat from frozen in a low oven.
