Healthy Crustless Quiche

WANT TO SAVE THIS RECIPE?

A slice of this Healthy Crustless Quiche is one of my favorite ways to ease into the day. It’s fluffy, custardy, and packed with tender broccoli and melty cheese, but it still feels light enough for a busy weekday morning. Without the pastry crust, every bite is pure eggy, veggie-filled goodness.

I love how easily this quiche slips into my routine. I can whisk everything together in minutes, bake it once, and enjoy satisfying breakfasts and quick lunches for days. It’s cozy enough for a slow Sunday brunch, but simple enough to throw together when you’re half-awake and craving something more exciting than plain scrambled eggs.

Why You’ll Love This Healthy Crustless Quiche

This crustless quiche has become a regular in my kitchen because it strikes that perfect balance of comfort and nutrition. The eggs and cheese bring protein and richness, while the broccoli adds color, texture, and a little extra veg that makes me feel good about having a second slice.

It’s naturally gluten-free, low in fuss, and endlessly flexible. Swap in whatever veggies you have, use up leftover cheese in the fridge, or add cooked bacon or ham if your family wants something heartier. It reheats beautifully, so it’s ideal for meal prep, and it fits right in next to simple brunch favorites like my air fryer egg and cheese toast for an easy, homey spread.

What Kind of Cheese Works Best in a Healthy Crustless Quiche?

I like to use a mix of sharp cheddar and a softer cheese like mozzarella or Swiss. The cheddar adds that tangy, savory bite that keeps the quiche from tasting flat, while the milder cheese melts into silky pockets throughout the custard.

If you prefer something a little more elegant, try swapping in Gruyère, or go for a bit of feta or goat cheese for extra creaminess and a salty kick. Just make sure you’re using cheese that melts well and shred it yourself if you can—bagged shredded cheese is convenient, but freshly grated cheese melts more smoothly and gives you a better texture in every forkful.

Ingredients for the Healthy Crustless Quiche

For this quiche, I reach for a short list of simple ingredients that I almost always have on hand. Each one plays a role in keeping the custard light, flavorful, and sturdy enough to slice.

• Eggs – The base of the quiche, providing structure, richness, and protein.
• Milk – Thins the eggs just enough and helps create that tender, custardy texture.
• Plain Greek yogurt or light cream – Adds creaminess and body without making the quiche heavy.
• Broccoli florets – Bring color, bite, and extra nutrients; they make the quiche feel hearty and wholesome.
• Shredded cheddar cheese – Adds sharp, savory flavor and a gooey, cheesy top.
• Shredded mozzarella or Swiss cheese – Melts smoothly and gives the quiche a soft, stretchy interior.
• Onion or green onions – A little sweetness and bite that keeps the flavor from feeling flat.
• Garlic – Adds warmth and savory depth in the background.
• Olive oil – For lightly sautéing the vegetables and adding a hint of richness.
• Salt and black pepper – Essential for bringing all the flavors to life.
• Dried Italian herbs or thyme – Adds gentle herbal notes that make the quiche taste a bit more special.
• Fresh parsley or chives – For a pop of freshness and color on top before serving.

How To Make the Healthy Crustless Quiche

Once the oven is preheating, this quiche comes together with a few easy steps. I like to prep the vegetables first, whisk the custard while they cool slightly, and then pour everything into the pan for a no-stress bake.

Step 1: Prep the pan and preheat the oven
Grease a 9-inch pie dish or similar baking dish with a little olive oil or nonstick spray. This keeps the quiche from sticking and helps you get those clean slices later. Preheat your oven to 375°F (190°C) so it’s ready when the quiche is assembled.

Step 2: Lightly cook the vegetables
In a skillet, warm a drizzle of olive oil over medium heat. Sauté the chopped onion until it’s soft and translucent, then add the broccoli florets with a pinch of salt. Cook just until the broccoli brightens in color and starts to become tender. You don’t want it mushy—it will finish cooking in the oven.

Step 3: Whisk together the egg mixture
In a large bowl, whisk the eggs until the yolks and whites are fully combined. Add the milk, Greek yogurt or light cream, salt, pepper, and dried herbs. Whisk until the mixture is smooth and slightly frothy; this helps give the quiche a lighter texture.

Step 4: Layer the fillings
Spread the cooked broccoli and onions evenly over the bottom of the prepared baking dish. Sprinkle the shredded cheeses over the vegetables, making sure they’re fairly evenly distributed so every slice gets a good mix of veggies and cheese.

Step 5: Pour and tap
Pour the egg mixture slowly over the vegetables and cheese. Gently tap the baking dish on the counter a few times to release any large air bubbles and help the custard settle into all the nooks and crannies.

Step 6: Bake until puffed and golden
Place the dish on the middle rack of the oven and bake for about 30–35 minutes, or until the quiche is set in the center and the top is lightly golden. The edges will puff up a bit as it bakes—that’s a good sign.

Step 7: Rest and garnish
Let the quiche rest for 10–15 minutes before slicing. This gives the custard time to fully set so you get clean wedges. Sprinkle with chopped fresh parsley or chives just before serving.

Serving and Storing Your Healthy Crustless Quiche

This recipe makes about 6 hearty slices, perfect for a family brunch or several grab-and-go breakfasts during the week. I love it warm right out of the oven with a side of simple greens or a little fruit on the plate.

To store leftovers, let the quiche cool completely, then cover the dish tightly or transfer slices to an airtight container. It will keep in the refrigerator for up to 4 days. You can reheat individual slices in the microwave for quick breakfasts, or warm them gently in a 325°F (165°C) oven until heated through.

For longer storage, wrap cooled slices in plastic wrap and then foil, and freeze for up to 2 months. Thaw overnight in the fridge and reheat as usual. I love pairing a reheated slice with a bowl of comforting classic baked mac and cheese on chilly evenings when I want both veggies and extra coziness.

What to Serve With Healthy Crustless Quiche?

When I’m building a full meal around this quiche, I like to keep the sides simple and complementary:

1. Fresh green salad – A light salad with mixed greens, lemon vinaigrette, and maybe a few cherry tomatoes keeps the plate bright and refreshing.
2. Crispy garlic air fryer broccoli – If you’re a serious broccoli lover, serve a side of my crispy garlic air fryer broccoli for extra crunch and flavor.
3. Healthy nut & seed energy cookies – For a brunch spread, a plate of healthy nut & seed energy cookies makes a fun, slightly sweet finish that still feels nourishing.
4. Cheeseburger French Fry Casserole – When I’m turning this into a breakfast-for-dinner night, a bubbly pan of Cheeseburger French Fry Casserole on the table makes everyone extra happy.

Frequently Asked Questions

Can I use frozen broccoli instead of fresh?
Yes, frozen broccoli works well here. Thaw it completely and pat it very dry with a clean towel or paper towels before sautéing. Excess moisture can water down the custard, so drying it well is key to keeping the quiche tender instead of soggy.

Can I make this quiche dairy-free?
You can swap the milk and Greek yogurt for your favorite unsweetened non-dairy milk (like almond or oat) and a dairy-free yogurt or a splash of coconut milk. Use a dairy-free shredded cheese that melts nicely. The texture will be slightly different, but you’ll still get a delicious, protein-packed bake.

How do I keep my crustless quiche from getting watery?
The biggest culprits are undercooked vegetables and too much liquid. Lightly sauté the broccoli and onions to cook off moisture before adding them to the dish, and measure your milk or cream accurately. If your oven runs cool, you may need a few extra minutes of baking so the center sets fully.

Can I add meat to this Healthy Crustless Quiche?
Absolutely. Cooked and crumbled bacon, diced ham, or cooked chicken sausage all work beautifully. Just make sure any meat is fully cooked and well-drained before you add it to the baking dish so it doesn’t add extra grease.

Is this recipe good for meal prep?
Yes, this quiche is perfect for meal prep. Bake it on a Sunday, let it cool, and slice it into wedges. Store the slices in individual containers so you can grab one for a quick breakfast, a light lunch, or an easy snack during the week. It’s one of my favorite savory options when I’m planning ahead.
