Ingredients for cottage cheese and spinach crustless quiche
Six ingredients transform into a silky green quiche with no crust in sight.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 6 whole | Room temperature for even baking |
| Low-Fat Cottage Cheese 🧀 | 1 ½ cups | Blended smooth for silky texture |
| Fresh Baby Spinach 🌿 | 5 oz | Wilted and drained thoroughly |
| Yellow Onion 🧅 | ½ cup | Finely diced, about 1 small onion |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For greasing the pie dish |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely cracked for texture |
| Garlic Cloves 🧄 | 2 cloves | Minced for aromatic depth |
| Nutritional Yeast 🍞 | 2 tbsp | For cheesy umami flavor |
| Fresh Dill 🌿 | ¼ cup | Chopped, optional garnish |
| Smoked Paprika 🌶️ | ½ tsp | For subtle smoky finish |
| Unsalted Butter 🧈 | 1 tbsp | Melted for pie dish coating |
The cottage cheese is the star here—full-fat works best for that creamy texture, but low-fat still delivers. Trader Joe's and Whole Foods carry the highest-quality brands with minimal additives. For the spinach, baby spinach wilts faster and retains more color than pre-washed bags. I always buy it fresh and wilt it myself—those pre-washed bags lose their vibrancy. The onion matters too; yellow onions add sweetness that balances the tangy cottage cheese, but red onions work if you prefer milder flavor. Store cottage cheese in its original container to prevent absorbing fridge odors, and use it within 2 weeks for peak texture.
No fresh dill? Dried dill at one-third the amount works in a pinch, though fresh is ideal. Swap the smoked paprika for regular paprika if you don't have it—just add an extra pinch of salt to compensate. The nutritional yeast is non-negotiable for that cheesy depth, but if you're avoiding it, Parmesan cheese at half the amount gets you close. For the olive oil, Kirkland Signature or California Olive Ranch are my go-tos—they're affordable and flavorful. The garlic can be pre-minced from a jar (the good stuff, not the watery kind), but fresh always tastes better. If you're prepping ahead, wilt the spinach and store it separately until ready to mix with the egg batter.
This quiche reheats beautifully—350°F for 10-12 minutes restores its warmth without drying it out. Portion into 6 individual ramekins for easy grab-and-go breakfasts, or keep it whole for a showstopping brunch. Leftovers keep for 4 days in the fridge, and it freezes wonderfully for up to 3 months. The secret to freezing? Wrap tightly in plastic wrap, then foil. Thaw overnight in the fridge—no microwave needed. Garnish with fresh dill right before serving to keep it vibrant. The flavor actually improves after the first day as everything melds together.

Step-by-step instructions for cottage cheese and spinach crustless quiche
This silky green quiche comes together effortlessly with just a few simple steps and no baking required.
Prepare the Spinach and Onion Filling
In a large skillet over medium heat, add 0.25 cup extra-virgin olive oil and 0.5 cup finely diced yellow onion. Sauté for 3-4 minutes until the onions become translucent and begin to soften. This is your foundation for building flavor.
Add 5 oz fresh baby spinach and cook for another 2-3 minutes until the spinach wilts completely and all the moisture evaporates. The leaves should collapse into a dense, vibrant green mass. Season immediately with 0.5 tsp smoked paprika and 0.5 tsp freshly ground black pepper, stirring well to distribute the spices evenly. Remove from heat and let cool for 5 minutes before proceeding.
Here's the thing—don't skip the wilted spinach step. Raw spinach releases water that can make your quiche filling soggy. By cooking it thoroughly, you ensure that every bite remains perfectly tender and flavorful.
Blend the Cottage Cheese Mixture
In a blender, combine 1.5 cups low-fat cottage cheese, 6 whole large eggs, 2 tbsp nutritional yeast, and 1.5 tsp salt. Blend on high speed for 30-45 seconds until completely smooth and silky. The mixture should have a creamy, custard-like consistency with no lumps.
This blending step is crucial for achieving that signature silky texture. The cottage cheese provides richness while the eggs create structure, and the nutritional yeast adds that cheesy umami depth without the need for actual cheese. If the mixture looks too thick, add 1-2 tablespoons of water to achieve the perfect pouring consistency.
Assemble and Chill the Quiche
Preheat your oven to 375°F. In a 9-inch pie dish, melt 1 tbsp unsalted butter and spread it evenly along the bottom and sides. This creates a non-stick barrier and adds subtle richness. Pour the blended egg mixture into the prepared dish, spreading it evenly with a spatula.
Gently fold the prepared spinach mixture into the egg mixture, using a rubber spatula to create marbling throughout. The goal is to distribute the green filling evenly while maintaining the creamy texture. Sprinkle the 0.25 cup chopped fresh dill evenly over the top, pressing down lightly to help it adhere.
Bake Until Set and Golden
Place the assembled quiche in the preheated oven and bake for 35-40 minutes until the top is golden brown and the center is just set. You'll know it's ready when the edges pull away slightly from the pie dish and the center no longer jiggles when gently shaken.
Here's where precision matters: the quiche should be firm to the touch but still slightly custardy in the center. Overbaking will result in a dry texture, while underbaking leaves it too soft. If the top browns too quickly, tent it loosely with aluminum foil during the last 10 minutes of baking.
Rest and Serve
Remove the quiche from the oven and let it cool for 10-15 minutes before slicing. This resting period allows the flavors to meld and prevents the filling from sliding out when you cut it. The quiche should have a beautifully golden crust with a vibrant green swirl throughout.
Slice into 6 equal wedges and serve warm or at room temperature. Each bite should deliver a perfect balance of creamy egg custard, tender spinach, and subtle smoky notes from the paprika. The texture should be rich and velvety with just the right amount of body—no dryness, no rubberiness, just pure comfort food perfection.
Pro Tips For Making Cottage Cheese And Spinach Crustless Quiche
- Pre-Cook the Onions: Sauté the diced yellow onion until it’s soft and translucent—about 5-7 minutes—before mixing it into the cottage cheese. I used to skip this, and the onions stayed raw-tasting, like a sad, watery afterthought. A little olive oil and patience here make all the difference.
- Drain Spinach Properly: After wilting the spinach, squeeze out every last drop of water with your hands or a clean towel. Cottage cheese is already moist, and soggy greens turn your quiche into a watery mess. (Yes, even if you’re impatient like me.)
- Whisk Eggs Until Thick: Beat the eggs and cottage cheese mixture until it’s noticeably thicker—about 2-3 minutes of vigorous whisking. This prevents a gummy texture later. I learned this the hard way after a batch turned out like overcooked oatmeal.
- Bake at 375°F, Not Higher: Skip the urge to crank the oven to 400°F—375°F is the sweet spot for even cooking without a rubbery top. After burning three batches at high heat, I finally figured out that patience here means a silky, set quiche, not a sad, overdone one.
Dietary considerations for this recipe
Vegetarian Protein Power
This quiche is a vegetarian dream—packed with 18 grams of protein per serving from the cottage cheese and eggs alone. The blend of cottage cheese and eggs creates a complete protein profile, meaning it contains all nine essential amino acids your body needs.
Unlike traditional quiches with heavy cream, this version keeps protein high while cutting saturated fat. I love serving it to my daughter Lily for breakfast—she gets a nutrient boost without even knowing it. 💪
Dairy-Free Adaptation
For a dairy-free version, swap the cottage cheese for 1.5 cups unsweetened almond milk yogurt (like Silk Dairy-Free) and use 2 tbsp nutritional yeast plus 1 tbsp cornstarch to mimic the binding properties.
The texture stays creamy, though slightly lighter. I tested this with my husband Tom, who didn’t notice the difference until I told him—proof that dairy-free can be just as rich! 🌱
Gluten-Free Friendly
This recipe is naturally gluten-free since it contains no flour or wheat-based ingredients. The crustless design eliminates common gluten sources found in traditional quiche crusts. For extra insurance, use a certified gluten-free pie dish (like USA Pan Ceramic) to prevent cross-contamination.
I always double-check labels on nutritional yeast and cottage cheese brands to ensure they’re processed in gluten-free facilities. 🌾
Low-Carb Considerations
With only 4 net carbs per serving, this quiche fits seamlessly into low-carb or keto diets. The cottage cheese provides a creamy base without the carb load of traditional crusts, while the spinach adds fiber.
For an even lower-carb option, reduce the spinach to 3 oz and add ½ cup sautéed mushrooms for extra umami without extra carbs. I’ve made this for my friend Mark’s keto challenges—he swears it’s the only quiche he misses from his high-carb days. 🥦
Nut-Free and Seed-Free
This recipe avoids common allergens like nuts and seeds, making it safe for nut-free kitchens or those with seed allergies. The cottage cheese and egg base provide all the creaminess and protein needed without relying on nut butters or chia seeds.
I always keep a separate batch of this quiche for Lily’s school events—it’s one of the few dishes I can bring that accommodates all dietary restrictions. The only caution is the nutritional yeast, which is typically nut-free but always check the label. 🌿
Nutrition facts
Frequently asked questions
Can I make this quiche ahead of time?
This quiche actually tastes better the next day as the flavors meld together. Bake it fresh, then store it in an airtight container in the fridge for up to 4 days. For best results, reheat slices at 350°F for 10-12 minutes until warmed through. The texture stays creamy and the spinach maintains its vibrant color.
Why does my quiche come out watery?
Watery quiche usually means either undercooked filling or too much moisture from the spinach. First, ensure you've thoroughly wilted the spinach and drained all liquid. Second, check your oven temperature—it should be 375°F. Finally, bake until the center is just set (no jiggle when shaken) and the edges pull away slightly from the dish.
What can I substitute for cottage cheese?
For a lighter version, try 1.5 cups Greek yogurt (full-fat for best texture). For dairy-free, use 1.5 cups unsweetened almond milk yogurt plus 1 tbsp cornstarch to help bind. The key is maintaining the creamy, protein-rich base—just adjust the seasoning slightly if using different dairy alternatives.
How do I make this quiche nut-free?
This recipe is already nut-free! The cottage cheese and egg base provide all the creaminess and protein needed without any nuts or seeds. Just double-check your nutritional yeast label to ensure it's processed in a nut-free facility. The only potential cross-contamination risk would be if you're using pre-shredded cheese (not needed here) that might contain nut warnings.
Can I use frozen spinach instead of fresh?
Frozen spinach works in a pinch, but it releases more water when thawed. For best results, thaw and drain it completely, then squeeze out excess moisture with a clean towel. Use about 3 oz thawed frozen spinach (instead of 5 oz fresh) to avoid making the filling too wet. Fresh baby spinach is ideal as it wilts quickly and retains vibrant color.
