Cheesy Potato & Spinach Quiche (No Crust)
If you love quiche but want something lighter and easier, this crustless version is a perfect solution. Without pastry, the focus stays on the creamy egg filling, tender potatoes, sautéed spinach, and melted cheese. It is comforting, satisfying, and naturally lower in carbohydrates than traditional quiche.
This recipe works beautifully for breakfast, brunch, or even a simple dinner with a side salad. It is also great for meal prep since it slices cleanly and reheats well. The potatoes give it heartiness, while spinach adds freshness and color.
Prep Time: 20 minutes
Cook Time: 40–45 minutes
Total Time: 60–65 minutes
Yield: 6 servings
Ingredients
For the Quiche
2 cups small gold or Yukon potatoes, peeled and diced
2 cups fresh spinach, roughly chopped
1 cup shredded cheddar or Gruyère cheese
4 large eggs
1 cup milk (whole or 2%)
1 small onion, finely chopped
2 cloves garlic, minced
1 tablespoon olive oil
Salt and black pepper, to taste
½ teaspoon dried thyme or Italian seasoning
Instructions
Preheat the oven to 375°F (190°C). Lightly grease a 9-inch pie dish or baking dish.
Bring a small pot of salted water to a boil. Add diced potatoes and cook for 8–10 minutes until just tender but not falling apart. Drain and set aside.
Heat olive oil in a skillet over medium heat.
Add chopped onion and sauté for 3–4 minutes until softened.
Stir in minced garlic and cook for 30 seconds until fragrant.
Add chopped spinach and cook until wilted, about 2 minutes. Remove from heat.
In a large bowl, whisk together eggs, milk, salt, black pepper, and dried thyme or Italian seasoning.
Spread cooked potatoes evenly in the prepared dish. Top with the spinach-onion mixture and shredded cheese.
Pour the egg mixture evenly over the vegetables and cheese.
Bake for 40–45 minutes, or until the center is set and the top is lightly golden. Let rest 10 minutes before slicing.
Tips
Cut potatoes into small, even cubes for consistent cooking.
Do not overboil potatoes; they should hold their shape.
Sautéing onions first builds deeper flavor.
Squeeze excess moisture from spinach if needed.
Use whole milk for a richer texture.
Allow the quiche to rest before slicing for cleaner cuts.
Lightly grease the dish to prevent sticking.
For extra color, sprinkle a little cheese on top before baking.
Check doneness by gently shaking the dish; the center should barely jiggle.
Store leftovers covered in the refrigerator for up to 3 days.
Variations
Add cooked bacon or ham for a heartier version.
Substitute feta for cheddar for a Mediterranean twist.
Add sautéed mushrooms for depth of flavor.
Use sweet potatoes instead of Yukon potatoes.
Stir in chopped sun-dried tomatoes for tanginess.
Add a pinch of red pepper flakes for heat.
Replace spinach with kale or Swiss chard.
Mix in fresh herbs like parsley or chives.
Use half-and-half instead of milk for extra richness.
Add roasted red peppers for color and sweetness.
