I love making this kale and mushroom quiche because it’s a simple way to enjoy fresh veggies in a cozy, cheesy dish. It’s perfect for breakfast, lunch, or even a light dinner, and it always feels like a little treat. I hope you enjoy making it as much as I do!
Most of the ingredients in this recipe are easy to find at any grocery store. If you don’t usually keep kale or mushrooms at home, you’ll want to pick up fresh ones from the produce section. The pie crust can be store-bought to save time, but if you like baking, making your own is a fun option. Cheese and eggs are common staples, but make sure to grab your favorite kind of shredded cheese to add a personal touch.
Ingredients For Kale And Mushroom Quiche Recipe
Kale: A leafy green vegetable that adds a fresh, slightly bitter flavor and lots of nutrients.
Mushrooms: These add a savory, earthy taste and a nice texture when sautéed.
Pie crust: The base of the quiche, which can be store-bought or homemade for a flaky, buttery foundation.
Eggs: The main binder that holds everything together and gives the quiche its rich, custardy texture.
Milk: Mixed with eggs to create a smooth filling that’s not too dense.
Cheddar cheese: Adds a sharp, creamy flavor, but you can use any cheese you like.
Salt: Enhances all the flavors in the dish.
Black pepper: Adds a little bit of spice and warmth to balance the other ingredients.
Technique Tip for This Quiche
One of the most important steps in this Kale And Mushroom Quiche Recipe is sautéing the kale and mushrooms until they’re tender. Here’s how to do it so your veggies turn out just right:
- Heat a little bit of oil or butter in a skillet over medium heat. You want it warm but not smoking.
- Add the sliced mushrooms first because they take a little longer to cook. Stir them around so they don’t stick or burn.
- After a few minutes, add the chopped kale. Keep stirring so everything cooks evenly.
- Cook until the mushrooms are soft and the kale has wilted down but still looks bright green. This usually takes about 5 to 7 minutes.
Doing this step carefully makes your quiche taste way better because the vegetables get a chance to release their flavors and soften up. If you skip sautéing, the kale might stay tough and the mushrooms could make the quiche watery. Plus, sautéing helps get rid of any extra moisture so the crust stays nice and crisp.
When I first tried this, I didn’t cook the mushrooms long enough, and the quiche ended up a bit soggy. Now, I always make sure to give the veggies enough time in the pan. Also, I like to add a pinch of salt while sautéing because it helps draw out moisture and brings out the natural taste of the kale and mushrooms. It’s a small step but makes a big difference!

How To Store / Freeze This Quiche
Allow the quiche to cool completely before storing. This helps prevent condensation, which can make the crust soggy.
Wrap the quiche tightly in plastic wrap or aluminum foil. Ensure it is sealed well to maintain freshness and prevent any odors from the fridge seeping in.
For short-term storage, place the wrapped quiche in the refrigerator. It will stay fresh for up to 3-4 days.
If you plan to store the quiche for a longer period, consider freezing it. First, wrap it in plastic wrap, then in a layer of aluminum foil to protect against freezer burn.
Label the wrapped quiche with the date to keep track of its storage time. Frozen quiche can be stored for up to 2 months.
To reheat refrigerated quiche, preheat your oven to 350°F (175°C). Place the quiche on a baking sheet and cover it loosely with aluminum foil. Heat for about 15-20 minutes or until warmed through.
For reheating frozen quiche, it's best to thaw it in the refrigerator overnight. Once thawed, follow the same reheating instructions as for refrigerated quiche.
If you're in a hurry, you can reheat frozen quiche directly from the freezer. Preheat your oven to 375°F (190°C), place the quiche on a baking sheet, cover with foil, and bake for 25-30 minutes. Remove the foil for the last 10 minutes to crisp up the crust.
Avoid reheating quiche in the microwave if possible, as it can make the crust soggy. If you must use a microwave, reheat individual slices on a microwave-safe plate for 1-2 minutes, checking frequently to avoid overcooking.
