Choosing the Right Ingredients for Your Spinach and Mushroom Cottage Cheese Crustless Quiche
The Foundation: Cottage Cheese and Eggs
The star of this crustless quiche is high-quality cottage cheese. Look for full-fat varieties with small curds for the creamiest texture. As for eggs, farm-fresh is best, but any large, grade A eggs will work beautifully. The combination creates a protein-rich base that holds everything together without the need for a crust.
Fresh Produce Selection
When selecting spinach, choose bunches with bright, crisp leaves rather than wilted ones. For mushrooms, cremini (baby portobello) offer more flavor than white button mushrooms, but either works well. Look for firm caps without slimy spots or excessive moisture.
Flavor Enhancers
Fresh herbs elevate this spinach and mushroom crustless quiche from good to exceptional. Thyme, chives, and a touch of nutmeg complement the earthy mushrooms perfectly. Don’t skip the aromatics garlic and shallots create a flavor foundation that makes this dish memorable.
Ingredients & Prep for Spinach and Mushroom Cottage Cheese Crustless Quiche

- 6 large eggs
- 2 cups cottage cheese (small curd, 4% fat recommended)
- 1/4 cup grated Parmesan cheese
- 1/4 cup all-purpose flour (or almond flour for gluten-free)
- 1 tsp baking powder
- 1/2 tsp salt
- 1/4 tsp black pepper

- 5 oz fresh spinach (about 4 cups)

Essential Preparation Steps
Start by washing your spinach thoroughly and drying it well. For mushrooms, avoid soaking them in water simply wipe with a damp cloth to remove any dirt. This preserves their earthy flavor and prevents a watery quiche.

Pro Tips for Perfect Spinach and Mushroom Cottage Cheese Crustless Quiche
Avoiding Common Pitfalls
The key to a perfectly textured crustless quiche is managing moisture. Always pre-cook vegetables to remove excess water, especially spinach and mushrooms which contain high amounts of moisture. Pat them dry with paper towels after cooking if necessary.
Kitchen Tool Recommendations
A good quality pie dish makes all the difference ceramic or glass distributes heat evenly. Invest in a microplane for fresh nutmeg grating, which adds a subtle warmth that pre-ground cannot match.
Storage and Reheating
This crustless quiche keeps beautifully in the refrigerator for up to 4 days, making it ideal for meal prep. For freezing, cut into individual portions and wrap well. Reheat in a 325°F oven until just warm through microwave reheating can make the texture rubbery.

Add sun-dried tomatoes, olives, and a sprinkle of oregano for a Mediterranean-inspired version that pairs beautifully with a simple green salad. Try our Christmas Morning Pancakes as a sweet companion for a complete brunch spread.
Herb Explosion

Yes, but be sure to thaw it completely and squeeze out ALL excess moisture using a clean kitchen towel. Use about 1/2 cup of thawed, squeezed frozen spinach in place of the fresh.
Is this recipe suitable for meal prep?
