Ingredients You’ll Need
- 10 oz. box frozen chopped spinach: A convenient option; just thaw and squeeze out excess moisture. You can substitute with fresh spinach, but the cooking time will increase.
- 8 oz. mushrooms: Button, cremini, or portabello work beautifully; they add earthy depth and a lovely texture.
- 1 garlic clove (minced): Fresh garlic infuses wonderful flavor; feel free to use garlic powder if you’re in a pinch.
- ⅛ tsp salt: A touch to enhance the natural flavors of the other ingredients.
- 1 tbsp cooking oil (divided): Any neutral oil works; it helps to sauté the mushrooms and coat the pie dish.
- 2 oz. feta cheese: Creamy and tangy, feta adds character. Swap it with goat cheese for a different flavor profile.
- 4 large eggs: They bind everything together and provide richness; room temperature eggs work best in this recipe.
- ¼ cup parmesan cheese (grated): This hard cheese adds a wonderful sharpness; you can replace it with pecorino or nutritional yeast for a vegan twist.
- ¼ tsp black pepper (freshly cracked): Choose freshly cracked for the most flavor; it uplifts the dish.
- 1 cup milk: Whole milk is preferred for creaminess, but you can swap it with almond milk or a dairy-free alternative for a lighter version.
- ½ cup mozzarella cheese (shredded): Melty and stretchy, mozzarella adds a delightful finish; consider using an Italian blend for an extra twist.
How to Make Crustless Quiche
- Preheat the Oven: Set your oven to 350ºF to ensure it’s hot and ready to help your quiche rise perfectly.
- Prepare the Spinach: Thaw the 10 oz. box of frozen chopped spinach. Squeeze out as much moisture as you can; this prevents a soggy quiche.
- Slice the Mushrooms: Rinse any dirt off the 8 oz. mushrooms and slice them thinly. Mince the garlic clove, making sure to distribute the flavors throughout the dish.
- Sauté the Vegetables: In a skillet, add the mushrooms, minced garlic, ⅛ tsp salt, and ½ tbsp cooking oil. Sauté over medium heat until the mushrooms release all their moisture. The skillet should be dry when they’re done.
- Prepare the Pie Plate: Coat a 9-inch pie plate with the remaining ½ tbsp cooking oil. This keeps your quiche from sticking and allows for easy serving.
- Layer the Filling: Spread the sautéed mushrooms, squeezed spinach, and crumbled feta cheese evenly in the pie plate. This combination forms the savory base.
- Mix the Egg Mixture: In a large bowl, whisk together the 4 large eggs, ¼ cup grated Parmesan, ¼ tsp black pepper, and 1 cup milk. Ensure everything is mixed smoothly.
- Pour and Top: Carefully pour the egg mixture over the layered veggies and cheese. Finally, sprinkle the ½ cup shredded mozzarella on top.
- Bake: Place the pie plate in the preheated oven and bake for about 50 minutes. You’ll know it’s ready when the top becomes golden brown and the internal temperature reaches 160ºF.
- Slice and Serve: Allow the quiche to cool slightly before slicing. Enjoy it warm or chilled — it’s delicious either way!
Storing & Reheating
To store your crustless quiche, let it cool completely, then cover it with plastic wrap or transfer it to an airtight container. Refrigerate for up to 4 days. If you’d like to keep it longer, freeze individual slices for up to 3 months. To reheat, simply pop it in a preheated oven at 350ºF for about 15-20 minutes, or until warmed through. Keep in mind that freezing may slightly alter the texture, but a quick reheat will bring back some of its charm!
