Ingredients for Spinach Mushroom Cottage Cheese Quiche

Everything here is simple and easy to find at any grocery store. Here’s exactly what you’ll need:

• 6 large eggs
• 1 cup full-fat or low-fat cottage cheese
• 2 cups fresh spinach, chopped
• 2 cups mushrooms, sliced
• 1 cup shredded mozzarella cheese
• 1/4 cup grated Parmesan cheese
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 tablespoon olive oil
• 1 teaspoon Italian seasoning
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

That’s it. No fancy ingredients, no hard-to-find items. Just real, wholesome food that comes together fast. I almost always have everything on this list already sitting in my fridge or pantry, which honestly makes this recipe even easier to love.

Ingredient Notes and Substitutions

Don’t stress if you need to swap something out. This recipe is pretty flexible. Here’s what works and what to watch out for:

• Cottage cheese: Full-fat gives you the creamiest result, but low-fat works just fine too. I’ve used both and honestly can’t tell a huge difference once it’s baked.
• Mozzarella: Feel free to swap it for cheddar, Gruyere, or any cheese that melts well. Cheddar adds a sharper flavor that I actually love sometimes.
• Spinach: Fresh is best, but frozen spinach works in a pinch. Just make sure it’s fully thawed and squeezed completely dry first. Wet spinach means a watery quiche, and nobody wants that.
• Mushrooms: Cremini, white button, or portobello all work great here. Use whatever you have on hand.
• Olive oil: Butter or avocado oil are both easy swaps with no real change to the final dish.

Equipment You Will Need

Nothing special here. You probably already have everything you need:

• 9-inch pie dish or baking dish
• Large skillet
• Large mixing bowl
• Whisk
• Wooden spoon or spatula
• Knife and cutting board
• Measuring cups and spoons

How to Make Spinach Mushroom Cottage Cheese Quiche

This whole thing comes together faster than you’d think. Just a little sauteing, some whisking, and the oven does the rest. Follow these steps and you’ll have a beautiful, golden quiche on your table in under an hour.

1. Preheat your oven to 375 degrees F and grease your 9-inch pie dish or baking dish well. Don’t skip the greasing step or you’ll be fighting with stuck slices later.
2. Heat olive oil in a large skillet over medium heat. Add the diced onion and sliced mushrooms and cook for 5 to 6 minutes until softened and starting to turn golden.
3. Add the minced garlic and chopped spinach to the skillet. Stir everything together and cook for another 1 to 2 minutes until the spinach wilts down. Remove from heat and set aside.
4. In a large mixing bowl, whisk the eggs and cottage cheese together until mostly smooth. A few small curds in there are totally fine.
5. Stir in the shredded mozzarella, grated Parmesan, Italian seasoning, salt, and black pepper until everything is combined.
6. Fold the cooked vegetable mixture into the egg base gently. You want everything evenly distributed without overmixing.
7. Pour the mixture into your prepared baking dish and spread it out evenly with a spatula.
8. Bake for 35 to 40 minutes. You’re looking for a golden top and a center that doesn’t jiggle when you gently shake the dish. If it still wobbles in the middle, give it another 3 to 5 minutes. A knife inserted in the center should come out clean.
9. Let the quiche rest for 10 full minutes before slicing. I know it’s tempting to dive right in, but this cooling time is what helps everything firm up and hold together when you cut it.

Sauté the Vegetables

Heat your tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and sliced mushrooms and let them cook for 5 to 6 minutes, stirring occasionally, until they’re soft and a little golden. Then add the minced garlic and chopped spinach. Spinach wilts fast, so just 1 to 2 minutes is all it needs. Once it’s wilted, take the skillet off the heat. If the spinach looks wet, press it gently with your spatula to push out any extra liquid before it goes into the egg mixture.

Mix the Egg and Cottage Cheese Base

Crack your 6 large eggs into a large bowl and add the full cup of cottage cheese. Whisk them together until the mixture looks mostly smooth. Don’t worry about getting it perfectly lump-free. A few small cottage cheese curds in there are completely fine and actually help create that creamy texture once baked. Next, stir in the mozzarella, Parmesan, Italian seasoning, salt, and pepper. Then fold in your cooked vegetable mixture gently until everything is evenly mixed through.

Bake Your Spinach Mushroom Cottage Cheese Quiche

Pour the filling into your greased baking dish and use a spatula to spread it out into an even layer. Slide it into your preheated 375 degree F oven and bake for 35 to 40 minutes. When it’s done, the top will be golden and the center will feel set, not jiggly. Give the dish a gentle shake to check. Once it’s out of the oven, let it cool for at least 10 minutes before you slice into it. That rest time really does matter for clean, beautiful slices.

Tips for a Perfect Spinach Mushroom Cottage Cheese Quiche

I learned some of these the hard way, so you don’t have to. My very first attempt came out watery and sad because I tossed the spinach straight into the egg mixture without squeezing out any of the liquid. The whole thing was basically a soggy mess. Never again. These tips make all the difference:

• Squeeze the spinach. This is the big one. Press cooked or thawed spinach firmly with your spatula or a clean kitchen towel before it goes anywhere near the egg mixture. Seriously, get as much liquid out as you can.
• Don’t skip the cooling time. Ten minutes feels like forever when it smells that good, but cutting too soon means crumbling slices instead of clean ones.
• Whisk the eggs and cottage cheese well. A good whisk gives you that creamy, custardy texture throughout every bite.
• Grease your dish generously. Don’t be shy with it. A well-greased dish means your slices lift out cleanly every time.
• Check the center before pulling it out. A toothpick or thin knife inserted in the middle should come out clean with no wet batter clinging to it.

Variations to Try

Once you’ve made this once, you’ll start seeing all kinds of ways to mix it up. Here are some of my favorite twists to keep things interesting:

• Add bell peppers or zucchini. Dice them small and toss them in with the onion and mushrooms. They cook down beautifully and add great color.
• Swap the seasoning. Try smoked paprika or cumin instead of Italian seasoning for a completely different vibe.
• Use feta instead of mozzarella. It adds a salty, tangy punch that works really well with the spinach.
• Stir in sun-dried tomatoes. Just a small handful adds so much concentrated flavor.
• Make mini quiches in a muffin tin. Reduce the bake time to about 20 to 25 minutes and you’ve got perfect grab-and-go portions for the whole week.

Serving Suggestions for Spinach Mushroom Cottage Cheese Quiche

This quiche is honestly great on its own, but here are some easy ways to round out the meal:

• Simple green salad. A handful of greens with a light vinaigrette is all you need alongside a warm slice.
• Fresh fruit. Berries, melon, or sliced oranges add a bright, sweet contrast.
• Whole grain toast. Perfect for soaking up every last bit.
• Roasted potatoes. Crispy potatoes on the side make this feel like a full brunch spread.
• Coffee or tea. Obviously. It’s brunch.

And remember, this quiche works just as well cold as it does warm. Pack a slice in your lunch bag or grab one straight from the fridge on a busy weekday morning. It travels well and tastes just as good a day or two later.

Storage and Reheating

This quiche stores really well, which makes it one of my favorite things to meal prep on a Sunday. Here’s how to keep it tasting great all week:

• Fridge: Store leftover slices in an airtight container in the fridge for up to 4 days.
• Freezer: Slice the quiche first, then wrap each piece individually and freeze for up to 2 months. Slicing before freezing makes it so much easier to grab just what you need.
• Microwave: Reheat a slice for 1 to 2 minutes and it comes out perfectly warm.
• Oven: For a slightly crispier result, reheat at 350 degrees F for about 10 minutes.

The best part is that this quiche holds up really well after reheating. It doesn’t turn rubbery or dry out like some egg dishes can. It tastes almost as good as the day you made it.

Frequently Asked Questions About Spinach Mushroom Cottage Cheese Quiche

Can I make this quiche ahead of time?
Yes, absolutely. This easy quiche recipe is actually great for making ahead. Bake it the night before, let it cool completely, then cover and refrigerate. It slices beautifully the next morning and tastes just as good warm or cold.

Can I use frozen spinach instead of fresh?
You can. Just make sure it’s fully thawed and squeezed as dry as possible before adding it. Frozen spinach holds a lot of water, and that extra moisture is exactly what turns a crustless quiche watery.

Why is my crustless quiche watery?
Nine times out of ten, it’s the spinach. Wet spinach releases liquid as it bakes and throws off the whole texture. Always press out the excess moisture before it goes into the egg mixture. Overcrowding the vegetables can also be a factor.

Can I add meat to this recipe?
Definitely. This is a vegetarian quiche as written, but cooked crumbled sausage, diced ham, or crispy bacon all mix in really well. Just fold them in with the vegetables before baking.

Is this quiche low carb?
Yes. With only 5 grams of carbohydrates per slice and no crust, this low carb quiche fits really well into a lower carb eating plan. The protein is high too, which helps keep you full.
