Ingredients at a Glance

6 large eggs
1 cup cottage cheese (use full-fat or low-fat as you prefer)
½ cup shredded mozzarella or cheddar cheese
1 cup cooked spinach, squeezed dry and chopped
½ cup milk (dairy or plant-based works great)
¼ teaspoon garlic powder
¼ teaspoon onion powder
Salt and black pepper, to taste
Optional: ¼ cup chopped green onions, mushrooms, or red bell pepper for extra flavor

Simple Whisk and Bake Method

Preheat oven to 375°F (190°C) and grease a 9-inch pie dish or 8×8-inch baking dish with olive oil or cooking spray.
If using fresh spinach, sauté in a splash of olive oil until wilted; if using frozen spinach, thaw fully; cool slightly, squeeze out all moisture, and chop.
Sauté any optional vegetables (mushrooms, bell pepper, zucchini) until tender and squeeze out excess moisture.
Optionally blend cottage cheese and milk until smooth for a creamier custard.
In a large bowl, whisk together eggs, cottage cheese (blended or not), shredded cheese, garlic powder, onion powder, salt, and pepper until smooth and creamy.
Gently fold the well-drained spinach and any optional veggies or herbs into the egg mixture.
Pour the mixture into the prepared dish and smooth the surface.
Bake at 375°F (190°C) for 35 to 40 minutes, until the center is set and the top is lightly golden brown (a knife inserted in the center should come out clean).
Alternatively, for mini quiches, pour the mixture into a greased muffin tin and bake for 18 to 22 minutes.
Let the quiche rest for 5 to 10 minutes before slicing.

Tips for Perfect Texture

Make sure to squeeze the spinach really well. Any extra water can make your quiche watery, and nobody wants that!
Want it creamier? Use full-fat cottage cheese or swap the milk for a splash of heavy cream.
If you prefer a super smooth custard-like texture, blend the cottage cheese and milk together quickly before adding the eggs.
Don’t overbake it—take it out as soon as the center is set but still slightly jiggly because the quiche will keep firming up as it cools.
Let it rest before slicing. This helps you get neat slices and avoids any crumbly mess.

This quiche shines on its own or paired with some simple sides. Try a crisp green salad or fresh fruit for a light meal. For brunch, serve with toasted crusty bread and a dollop of sour cream or a side of salsa. It also makes great sandwich filling once cooled, rolled up with a little mayo and lettuce.

Swaps and Additions

Swap out greens: try chopped kale or Swiss chard instead of spinach. Just sauté until tender and squeeze dry.
Bring in more veggies: add sautéed mushrooms, diced bell pepper, or grated zucchini (make sure to squeeze zucchini dry to avoid sogginess).
Cheese swap ideas: feta, Gruyère, or goat cheese can add new flavor layers.
Protein boost: toss in cooked, crumbled bacon or diced ham if you’re not keeping it vegetarian.
Add fresh herbs or spices like dill, parsley, chives, or a pinch of nutmeg to give your quiche a little twist.
Make mini quiches: pour the mixture into a greased muffin tin and bake for 18 to 22 minutes for easy, individual portions perfect for snacking or lunches.

Want to mix things up? Go wild with your favorite veggies and cheeses. Add sun-dried tomatoes, roasted red peppers, or swap the spinach for kale or Swiss chard. Sprinkle in some different cheese like feta or sharp cheddar to change the flavor profile. For a heartier meal, toss in cooked sausage or bacon.

Storing, Freezing, and Reheating

Once your quiche has cooled, store it in an airtight container in the fridge for up to 4 days. If you want to freeze it, slice the quiche after it’s completely cooled, wrap each slice tightly in plastic wrap or foil, and place the slices in an airtight container or freezer bag. They’ll keep well for up to 2 months. When you’re ready to eat, reheat refrigerated slices in the microwave for 30 to 60 seconds or warm them in a 350°F (175°C) oven for 10 to 15 minutes. For frozen slices, thaw them overnight in the fridge before reheating or warm them slowly from frozen in the oven until hot all the way through.

Keep your quiche fresh by storing it in an airtight container in the kitchen fridge for up to four days. Make sure it’s completely cool before putting it away so it holds up well. If you don’t plan to eat it soon, wrap slices tightly for the freezer to avoid freezer burn—it’s a lifesaver when busy weeks hit.

This quiche is perfect for making ahead. You can assemble and bake it a day or two in advance, then simply reheat before serving. Alternatively, mix the filling the night before and keep it covered in the fridge—just add the spinach and bake fresh in the morning. This saves you precious time on hectic mornings.

Frequently Asked Questions

Can I freeze crustless quiche?
Yes! Just let it cool completely, slice it, wrap individual portions, and freeze for up to 2 months. Thaw overnight in the fridge to keep the texture just right before reheating.

Is cottage cheese good for baking?
Definitely. Cottage cheese adds creaminess, moisture, and protein. If you want a smoother mix, blend it with the milk before whisking in the eggs.

Can I use frozen spinach?
Absolutely! Just thaw it fully and squeeze out all the excess water to avoid a watery quiche.

How do I know when the quiche is done?
Look for lightly golden edges and a center that’s just set. A clean knife test in the middle should confirm it’s ready. Remember, it will continue to firm up as it cools.

Can I make this dairy-free?
You can swap in plant-based milk and dairy-free shredded cheese, but cottage cheese really contributes to the creamy texture and protein here. For a dairy-free alternative, try mashed silken tofu or thick unsweetened vegan yogurt, but keep in mind results might change a bit.
