Step-by-Step Instructions
Prepare the Potatoes
Preheat the oven to 375°F (190°C).
Peel the potatoes and slice them into rounds approximately ¼-inch thick.
Bring a large pot of lightly salted water to a gentle boil.
Add the potato slices and cook for approximately 5–7 minutes, or until they are just fork-tender.
Do not overcook them because they will continue cooking in the oven.
Drain the potatoes carefully and set them aside.
Cook the Spinach
Heat the butter or olive oil in a large skillet over medium heat.
Add the minced garlic and cook for approximately 30 seconds, until fragrant.
Add the fresh spinach.
Cook for 1–2 minutes, stirring frequently, until the spinach has wilted.
Remove from the heat.
Allow the spinach to cool slightly, then squeeze out as much excess moisture as possible using a clean kitchen towel or paper towels.
This step is important because excess water can make the quiche soggy.
Prepare the Egg Custard
Crack the eggs into a large mixing bowl.
Add the heavy cream, salt, black pepper, and dried herbs.
Whisk until the mixture is smooth and evenly combined.
Do not over-whisk because incorporating too much air can cause the custard to puff excessively and then collapse.
Assemble the Quiche
Grease a 9-inch round baking dish, cake pan, or oven-safe skillet with butter or cooking spray.
Arrange a layer of potato slices across the bottom.
Add a portion of the garlic spinach.
Sprinkle with some of the shredded cheese.
Repeat the layers with the remaining potatoes, spinach, and cheese.
Slowly pour the egg custard over the entire dish.
Gently shake the pan or use a spatula to help the custard move between the potato and spinach layers.
Finish with the remaining shredded cheese.
Bake
Place the baking dish in the preheated oven.
Bake at 375°F (190°C) for 35–45 minutes.
The quiche is ready when the center is set and no longer visibly liquid or jiggly.
The top should be melted, bubbling, and lightly golden.
If the top is browning too quickly while the center still needs time, loosely cover the dish with aluminum foil and continue baking.
Cool and Serve
Remove the quiche from the oven.
Allow it to rest for 10–15 minutes before slicing.
This cooling period helps the egg custard firm up and makes it easier to cut clean wedges.
Garnish with fresh parsley if desired.
Serve warm or at room temperature.
Best Tips
Use Yukon Gold potatoes because they have a naturally creamy texture and hold their shape well during baking.
Slice the potatoes evenly so every layer cooks at the same rate.
Do not skip squeezing the spinach. Removing excess moisture is one of the most important steps for achieving a firm quiche.
Avoid overcooking the potatoes before baking. They only need to become fork-tender.
For a richer quiche, use heavy cream. For a lighter version, use half-and-half or milk.
Let the quiche rest before slicing. Cutting it immediately can cause the custard to spread.
Best Ingredient Options
Yukon Gold potatoes are ideal, but red potatoes can also work well.
Cheddar gives the quiche a stronger savory flavor, while mozzarella creates a softer, stretchier cheese layer.
For extra flavor, use a combination of cheddar, mozzarella, and Parmesan.
Fresh baby spinach is convenient, but frozen spinach can also be used. Thaw it completely and squeeze out as much water as possible before adding it.
Heavy cream creates the richest custard, while half-and-half provides a lighter result.
Fresh herbs can be used instead of dried herbs for a brighter flavor.
Recipe Variations
Spinach and Feta Quiche
Replace part of the shredded cheese with ½ cup crumbled feta for a salty, tangy flavor.
Mushroom and Spinach Quiche
Sauté 1 cup sliced mushrooms with the garlic before adding the spinach.
Cook until the mushrooms release their moisture and become lightly browned.
Tomato and Spinach Quiche
Add ½ cup halved cherry tomatoes for a fresh, colorful variation.
Pat the tomatoes dry before adding them to prevent excess moisture.
Bacon and Spinach Quiche
Add ½ cup cooked and crumbled bacon between the potato layers.
For a pork-free alternative, use cooked turkey bacon or seasoned chicken pieces.
Broccoli and Cheese Quiche
Replace some of the spinach with lightly steamed broccoli florets.
Cheddar and broccoli make an especially delicious combination.
Mediterranean Version
Add spinach, feta, roasted red peppers, olives, oregano, and mozzarella for a Mediterranean-inspired variation.
What to Serve With
Serve a slice of this potato and spinach quiche with a simple green salad for a balanced meal.
Fresh fruit makes an excellent side for breakfast or brunch.
Roasted tomatoes, avocado, or cucumber salad also pair beautifully with the creamy quiche.
For a heartier dinner, serve it with roasted vegetables and crusty bread.
Make-Ahead Instructions
This quiche is excellent for meal preparation.
You can bake the entire quiche up to 1 day ahead.
Allow it to cool completely before covering and refrigerating.
When ready to serve, reheat it gently in the oven until warmed through.
You can also prepare the spinach and potatoes ahead of time and store them separately in the refrigerator.
Storage
Allow leftovers to cool completely.
Place individual slices in airtight containers or cover the entire baking dish tightly.
Store in the refrigerator for 3–4 days.
Keep refrigerated at 40°F (4°C) or below.
Reheating
For the best texture, reheat individual slices in a 350°F (175°C) oven for approximately 10–15 minutes.
You can also microwave a slice for approximately 60–90 seconds, depending on your microwave.
Avoid overheating because the eggs can become rubbery.
Freezing
The baked quiche can be frozen.
Allow it to cool completely, then cut it into individual portions.
Wrap each slice tightly and place the portions in a freezer-safe container or bag.
Freeze for up to 2 months for the best quality.
Thaw overnight in the refrigerator before reheating.
For the best texture, reheat thawed slices in a 350°F (175°C) oven.
Common Mistakes to Avoid
Do not add wet spinach directly to the quiche. Excess moisture can prevent the custard from setting properly.
Avoid cutting the potatoes too thick because they may remain firm in the center.
Do not overcook the potatoes during the pre-cooking stage.
Avoid adding too much cheese because excessive cheese can release oil and make the quiche greasy.
Do not remove the quiche from the oven while the center is still liquid.
Avoid slicing immediately after baking. Give the quiche at least 10 minutes to set.
