Low Carb Crustless Broccoli Cheddar Quiche – Easy & Best

It was 10:47 PM on a rainy Tuesday, and I had a desperate, almost irrational craving for something warm, cheesy, and deeply satisfying. The problem? My fridge was looking pretty sad. I had a head of broccoli that was starting to wilt, a block of cheddar, and a dozen eggs. No cream. No pie crust. No energy for a grocery run. Honestly, I almost just made scrambled eggs and called it a night. But then I remembered a trick I’d seen in a cooking forum years ago—using cottage cheese to add creaminess without the heavy cream. I grabbed my whisk, cracked the eggs, and started chopping. I didn’t know if it would work. I mean, a crustless quiche? It felt like a gamble. But twenty-five minutes later, I pulled this golden, puffy, bubbling dish out of the oven, and the smell—sharp cheddar, earthy broccoli—filled my tiny apartment. It was so good, I ate a slice standing over the counter, still in my pajamas. That night, this crustless broccoli cheddar quiche became my new favorite thing. Maybe you’ve been there—tired, hungry, and just needing something that feels like a hug. This is that recipe.

What makes this version different? It’s the cottage cheese. Blending it creates an ultra-smooth, custard-like texture that feels decadent without the carbs. Plus, roasting the broccoli first (yes, I’ll show you how) brings out a nutty sweetness that takes this from good to “close your eyes after the first bite” good. It’s a low-carb crustless quiche that doesn’t taste like a compromise.

What Ingredients You Will Need

This recipe relies on a handful of simple, wholesome ingredients to deliver big flavor. Most of these are kitchen staples, which makes this dish incredibly easy to throw together on a whim.

• Broccoli florets (3 cups, chopped): Fresh is best here for texture. Look for firm, bright green heads. You’ll want them chopped into small, bite-sized pieces so they cook evenly.
• Large eggs (6): The backbone of the quiche. Use room-temperature eggs for the smoothest, fluffiest texture. If you’re in a rush, place them in a bowl of warm water for 5 minutes.
• Cottage cheese (1 cup, full-fat): This is my not-so-secret weapon. Blended smooth, it replaces heavy cream and adds incredible creaminess and a protein boost. I recommend Good Culture or Daisy for their thick, clean texture.
• Sharp cheddar cheese (1.5 cups, shredded): Don’t skimp on the quality here. A sharp, aged cheddar gives the most flavor. I love Cabot or Tillamook. Shred it yourself from a block—it melts so much better than pre-shredded.
• Onion (1/2 medium, diced): Adds a savory depth. Yellow or white onion works perfectly. Sauté it first to mellow the bite.
• Garlic (2 cloves, minced): Fresh is non-negotiable here. It infuses the whole dish with a warm, aromatic flavor.
• Olive oil (1 tablespoon): For roasting the broccoli and sautéing the onion and garlic.
• Salt and black pepper (to taste): Don’t be shy. Seasoning the layers properly is key to a flavorful quiche.
• Optional: Red pepper flakes (1/4 teaspoon): For a tiny kick of heat. I add this almost every time.

Equipment Needed

You don’t need a professional kitchen to make this low-carb crustless broccoli cheddar quiche. Here’s what you’ll need:

• 9-inch pie dish or 8×8 baking dish: A standard pie dish works perfectly. If using an 8×8, the quiche will be slightly thicker and may need an extra 2-3 minutes of baking.
• Mixing bowls: One large bowl for the egg mixture and one small for the blended cottage cheese.
• Blender or food processor: For smoothing out the cottage cheese. An immersion blender works great too.
• Baking sheet: For roasting the broccoli. A rimmed sheet is best.
• Skillet: For sautéing the onion and garlic.
• Whisk: For beating the eggs. A fork works in a pinch.
• Cheese grater: Please, for the love of cheese, grate your own. It makes a world of difference.

Preparation Method

1. Preheat and Prep: Preheat your oven to 400°F (200°C). Lightly grease your pie dish with butter or cooking spray. This prevents sticking and makes cleanup a breeze.
2. Roast the Broccoli: Toss your chopped broccoli florets with 1/2 tablespoon of olive oil and a pinch of salt. Spread them in a single layer on a baking sheet. Roast for 10-12 minutes, until they are bright green and just starting to get tender. This step is crucial—it brings out a nutty, sweet flavor and removes excess moisture. You’ll notice the difference immediately.
3. Sauté the Aromatics: While the broccoli roasts, heat the remaining 1/2 tablespoon of olive oil in a small skillet over medium heat. Add the diced onion and cook for 3-4 minutes until translucent. Add the minced garlic and cook for another 30 seconds until fragrant. Be careful not to burn the garlic. Set aside to cool slightly.
4. Blend the Cottage Cheese: In your blender or food processor, add the cup of cottage cheese. Blend for about 30 seconds until it is completely smooth and creamy. It should look like thick yogurt. This is your secret weapon for that silky texture.
5. Whisk the Egg Base: In your large mixing bowl, crack the 6 eggs. Whisk them vigorously for about 1 minute until they are frothy and well-combined. Add the blended cottage cheese and whisk again until fully incorporated. The mixture should be a uniform, pale yellow color.
6. Combine the Fillings: To the egg mixture, add the roasted broccoli, sautéed onion and garlic, 1 cup of the shredded cheddar cheese (reserve 1/2 cup for the top), salt, pepper, and red pepper flakes if using. Stir gently with a spatula until everything is evenly distributed. Don’t over-mix.
7. Assemble and Top: Pour the entire mixture into your prepared pie dish. Spread it into an even layer with your spatula. Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top. This creates that irresistible golden crust.
8. Bake to Perfection: Place the dish in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the center is just set—it should jiggle slightly but not be liquid. The top should be golden brown and puffed up. A knife inserted into the center should come out clean.
9. Rest and Serve: This is the hardest part. Let the quiche rest in the dish for at least 10 minutes before slicing. This allows the eggs to finish setting and makes for clean, beautiful slices. It will deflate a bit as it cools—that’s totally normal.

Cooking Tips & Techniques

Let me save you from my own mistakes. I’ve made this crustless broccoli cheddar quiche more times than I can count, and I’ve learned a few things the hard way.

The Watery Quiche Problem: The biggest issue with a crustless quiche is a watery, soggy bottom. The fix is two-fold. First, always roast your broccoli. Steaming or boiling adds too much moisture. Roasting concentrates the flavor and dries it out. Second, don’t skip the resting time after baking. It gives the eggs time to firm up completely.

Don’t Over-Bake: A quiche that’s over-baked becomes rubbery and dry. You want it to be just set in the center. The residual heat will finish the cooking process as it rests. If you’re unsure, err on the side of slightly under-done.

Room Temperature is Key: Cold eggs can shock the mixture and lead to a less fluffy texture. Let your eggs sit on the counter for 15-20 minutes before you start. It’s a small step that makes a big difference.

Multitasking Magic: While the broccoli roasts, you can sauté the onions and blend the cottage cheese. This cuts your active prep time down to almost nothing. I like to get all my ingredients measured and prepped before I even crack an egg—it makes the process feel effortless.

Variations & Adaptations

This low-carb crustless quiche is incredibly forgiving. Here are a few ways to make it your own:

• Make it Dairy-Free: Use a dairy-free shredded cheese (I like Miyoko’s cheddar style) and replace the cottage cheese with a block of silken tofu, blended smooth. It won’t be exactly the same, but it’s surprisingly creamy and delicious.
• Swap the Veggies: Not a broccoli fan? Try chopped asparagus, sautéed mushrooms, or roasted bell peppers and zucchini. Just make sure to cook them first to remove excess moisture.
• Add Protein: Make it a full meal by adding 1/2 cup of cooked, crumbled bacon, diced ham, or cooked breakfast sausage. Fold it in with the broccoli before baking.
• Change the Cheese: Sharp cheddar is classic, but this works beautifully with Gruyère, Monterey Jack, or even a smoky gouda. A mix of cheeses is always a good idea.
• Spice It Up: Add a pinch of smoked paprika, a dash of hot sauce to the egg mixture, or some chopped pickled jalapeños for a Southwestern twist.

Serving & Storage Suggestions

This crustless broccoli cheddar quiche is incredibly versatile. Here’s how to enjoy it:

Serving: Serve it warm, at room temperature, or even cold straight from the fridge (I won’t judge). It’s fantastic for breakfast with a side of fresh fruit, for lunch with a simple green salad dressed with a tangy vinaigrette, or for a light dinner. A dollop of sour cream or a sprinkle of fresh chives on top adds a nice finishing touch.

Storage: Let the quiche cool completely, then cover the dish tightly with plastic wrap or transfer slices to an airtight container. It will keep in the refrigerator for up to 4 days. The flavors actually meld and get better after a day in the fridge.

Reheating: The best way to reheat is in a 350°F (175°C) oven for about 10 minutes, or until warmed through. This helps the edges get slightly crispy again. You can microwave individual slices for 30-45 seconds in a pinch, but the texture won’t be as good.

Freezing: Yes, this freezes beautifully! Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. They’ll keep for up to 2 months. Thaw overnight in the fridge and reheat as directed above.

Frequently Asked Questions

Can I use frozen broccoli?

Yes, but you must thaw and drain it very well. Then, pat it dry with paper towels and roast it for a few minutes to remove the extra moisture. If you skip this step, you’ll end up with a watery quiche.

Why did my quiche turn out watery?

This usually happens for one of two reasons: the broccoli wasn’t roasted long enough to remove moisture, or the quiche wasn’t baked long enough. Make sure your broccoli is tender and slightly dry around the edges after roasting. Also, make sure the center of the quiche is just set before you pull it from the oven.

Can I make this crustless quiche ahead of time?

Absolutely! This is a fantastic make-ahead meal. Bake it completely, let it cool, and store it in the fridge. You can reheat individual slices or the whole thing. It’s even better the next day.

Can I use a different type of cheese?

Definitely. Sharp cheddar is my favorite for its bold flavor, but Gruyère, Monterey Jack, or a mix of your leftover cheeses will work beautifully. Just make sure it’s a cheese that melts well.

How do I know when the quiche is done?

The center should be just set and will jiggle slightly when you gently shake the dish. A knife inserted into the center should come out clean. The top should be golden brown and puffed. If the center still looks liquid, give it another 3-5 minutes.
