Key Ingredients in a Healthy Spinach Mushroom Quiche
This quiche is built on wholesome ingredients that work harmoniously to create a rich, creamy filling. Here’s what you’ll need:
- Fresh spinach or frozen spinach – both work, but make sure to squeeze out all the moisture if using frozen
- Mushrooms – cremini, button, or baby bella mushrooms bring that earthy flavor
- Cottage cheese – this is our star protein booster and creaminess factor
- Eggs – to bind it all together
- Onion and garlic – for added aroma and depth
- Cheese – cheddar, feta, or mozzarella (your choice!)
- Seasonings – nutmeg, salt, pepper, and optional chili flakes for a kick
- Optional crust – use a store-bought or homemade crust, or go crustless for a low-carb option
This quiche is adaptable and easily customizable, which makes it a favorite among home cooks.
How to Make a Crustless Cottage Cheese Quiche Step-by-Step
Let’s break it down into manageable steps. Even if you’re new to baking quiche, don’t worry. This one is foolproof.
1. Preheat Your Oven
Start by preheating your oven to 375°F (190°C). If you’re using a crust, blind bake it for 10 minutes to prevent sogginess.
2. Sauté Your Vegetables
In a skillet, heat a tablespoon of olive oil over medium heat. Add diced onion and sauté until translucent. Then toss in your sliced mushrooms. Let them cook until they release and evaporate their moisture. Finally, add spinach and cook until wilted. Set aside to cool slightly.
3. Prepare the Filling
In a large mixing bowl, whisk 4 large eggs. Stir in 1 cup of cottage cheese, 1/2 cup of shredded cheese (your choice), and your sautéed veggies. Season generously with salt, pepper, and a pinch of nutmeg. If you’re feeling adventurous, toss in some chili flakes or chopped fresh herbs.
4. Assemble and Bake
Pour your mixture into a prepared pie dish or quiche pan. Bake for 35-40 minutes or until the center is just set and the top is golden. Let it rest for 10 minutes before slicing.
You’ve got yourself a creamy, protein-packed, savory masterpiece.
Variations for a Vegetarian High-Protein Quiche
The beauty of this recipe is its flexibility. Feel free to tweak it based on what you have in the fridge or your dietary preferences.
- Go crustless: Skip the crust to make it gluten-free and lower in calories.
- Add protein: Crumbled bacon, cooked ham, or diced turkey sausage are perfect if you’re not vegetarian.
- Mix up the cheese: Feta adds tang, mozzarella keeps it mild, and aged cheddar gives it sharpness.
- Switch the greens: Try kale, chard, or arugula for a twist.
Experimentation is encouraged, and chances are, you’ll stumble on a new favorite combo.

Quiche-Making Mistakes to Avoid
