Broccoli and Cheese Crustless Quiche Recipe: Golden Egg Custard With Hidden Veggie Power

This crustless broccoli and cheese quiche delivers all the comfort of a classic quiche without the carb-heavy crust—just rich, golden egg custard packed with tender broccoli and sharp cheddar. The secret lies in blending steamed broccoli into the egg mixture, creating a silky texture while keeping the veggie power hidden.

I developed this recipe after years of experimenting with vegetarian breakfasts that actually satisfy, and it’s become a staple in my rotation.

The beauty of this quiche is its versatility—it bakes up with a golden, fluffy top that’s crisp at the edges and custardy inside, while the broccoli adds subtle earthiness that balances the cheesy richness.

Using a mix of sharp cheddar and cream cheese ensures a perfect melt, and the addition of a touch of mustard adds depth without overpowering. It’s the kind of dish that feels indulgent yet stays light enough for breakfast or brunch.

What makes this recipe truly foolproof is the technique: pre-steaming the broccoli removes excess moisture, preventing a soggy quiche, while whipping the eggs until slightly thickened creates that signature lifted, cloud-like texture.

Baking at 350°F for 35-40 minutes guarantees a perfectly set custard without drying out. The result? A slice that’s creamy, cheesy, and packed with nutrients—no one will guess it’s secretly good for you.

Serve it warm with a side of roasted tomatoes or a simple arugula salad for a complete meal, or enjoy it cold the next day for an effortless lunch.

The recipe also adapts easily to dietary needs—swap the cheese for dairy-free alternatives or add spinach for extra greens. Ready to transform your breakfast game?

Ingredients for broccoli and cheese crustless quiche

Six eggs, two cheeses, and broccoli that disappears into golden custard—no crust needed.

The broccoli is the unsung hero here. Fresh florets from the grocery store’s produce section (not the pre-cut bags) hold up best when steamed—just 3-4 minutes until bright green and fork-tender. I grab mine from Whole Foods when I can, but the regular supermarket stuff works fine if it's crisp. The key is removing ALL moisture before blending—pat it dry with paper towels or even squeeze it gently in a clean kitchen towel. For the cheeses, sharp white cheddar is non-negotiable—it melts perfectly and adds that signature tang. The cream cheese? Philadelphia brand is my go-to, but any full-fat block works if you grate it yourself. Pre-shredded gets clumpy and adds anti-caking agents that ruin the texture.

No sharp cheddar? Pepper jack at half the amount adds heat, or Gruyère for nutty depth. Running out of cream cheese? Ricotta at the same quantity works in a pinch—just blend it longer. The mustard is crucial for that subtle tang that cuts through the richness, but if you're sensitive to strong flavors, Dijon at half the amount is a good start. For the eggs, if you're using the kind with those little cartons in the shell, room temperature makes all the difference—cold eggs won’t whip as smoothly. The nutmeg is optional but worth it—it adds a warm, earthy note that balances the cheesy sweetness. No nutmeg? Ground cinnamon at one-third the amount gives a similar vibe.

This quiche keeps beautifully—3 days in the fridge wrapped tightly in foil, or 2 months in the freezer if you portion it into slices first. Reheat gently in a 300°F oven until the center is just warm through. The best part? It reheats even better than it tastes fresh. I always make a double batch—one for breakfast, one for lunch the next day. The leftovers reheat perfectly and taste even richer once the flavors meld. For meal prep, slice it before freezing so you can grab just what you need.

Step-by-step instructions for broccoli and cheese crustless quiche

Here's how to create a rich, golden quiche with hidden broccoli and a velvety egg custard—no crust needed.

Cut the stems off the 4 cups fresh broccoli florets and divide them evenly between two microwave-safe bowls. Cover each bowl tightly with plastic wrap and pierce the wrap with a fork to allow steam to escape. Microwave on high for 3-4 minutes until the broccoli is tender when pierced with a fork—it should yield slightly but still hold its shape.

Drain the broccoli thoroughly in a colander and press out any excess moisture with a clean kitchen towel. This step is crucial because too much liquid will make your quiche custard watery. Once cooled, chop the broccoli into small, even pieces—about ½-inch in size—for even distribution in the quiche.

In a large mixing bowl, combine the 6 whole large eggs, 0.5 cup heavy whipping cream, 1 tablespoon Dijon mustard, 0.25 cup all-purpose flour, 0.25 teaspoon freshly grated nutmeg, 1 teaspoon Diamond Crystal kosher salt, and 0.5 teaspoon freshly ground black pepper. Whisk vigorously until the mixture is completely smooth and uniform in color—no streaks of flour should remain.

In a separate medium bowl, mix the 2 cups sharp white cheddar cheese and 8 ounces cream cheese together with a fork until it forms a crumbly, well-blended mixture. Gradually add this cheese mixture to the egg mixture while whisking continuously. The goal is to create a thick, velvety batter that coats the back of a spoon. If the mixture seems too thick, add 1-2 tablespoons of water to loosen it slightly.

Heat 1 tablespoon of the extra-virgin olive oil in a 9-inch oven-safe skillet over medium heat. Add the 2 minced garlic cloves and sauté for 30 seconds until fragrant—don't let them brown. Remove the skillet from heat and pour in the remaining 1 tablespoon of olive oil, swirling to coat the bottom evenly. This step ensures the quiche has a rich, flavorful foundation.

Spread half of the steamed broccoli evenly across the bottom of the skillet, creating a single layer. Pour the egg and cheese mixture over the broccoli, tilting the skillet gently to distribute it evenly. Sprinkle the remaining broccoli evenly on top, pressing down lightly to ensure it's fully submerged in the custard. This layering technique guarantees every bite has that perfect broccoli-to-cheese ratio.

Preheat your oven to 375°F. Place the skillet on the center rack and bake for 35-40 minutes until the edges are golden brown and the center is just set—it should still have a slight wobble like gelatin when gently shaken. Avoid opening the oven door during baking to prevent the quiche from sinking.

To check for doneness, insert a knife near the center—it should come out clean with no raw egg clinging to it. If the top browns too quickly but the center isn't set, tent the quiche with aluminum foil to prevent over-browning while it finishes cooking. Let the quiche rest for 10 minutes before slicing—this allows the custard to set completely and makes serving easier.

Essential equipment for perfect results

Oven-Safe Skillet

The star of this recipe is a 9-inch oven-safe skillet—I swear by All-Clad Stainless Steel for its even heat distribution and durability, but any oven-safe, non-reactive skillet (like Le Creuset or Ceramic Core) works perfectly.

Avoid non-stick coatings if possible, as they can degrade at high heat. The skillet’s size is critical: too small, and the quiche won’t bake evenly; too large, and the edges may overcook before the center sets. 🔥

Mixing Bowls

Use two medium mixing bowls—one for the egg mixture and one for the cheese—to keep things organized. I prefer stainless steel for its non-reactive properties, but glass or ceramic bowls work too.

The egg mixture needs a large bowl (like Pyrex 2-quart) to accommodate the whisking, while the cheese mixture fits comfortably in a smaller bowl (about 1.5-quart). Avoid plastic if you’re using sharp cheddar, as it can scratch.

Whisk and Spatula

A balloon whisk (like OXO Good Grips) is essential for blending the egg mixture smoothly—it incorporates air for that signature fluffy texture. For the cheese, a rubber spatula (I use Silpat) helps scrape every last bit from the bowl.

A small offset spatula (like Mercer Culinary) comes in handy for spreading the broccoli evenly in the skillet without tearing the custard.

Measuring Tools

Precision matters here, especially with the flour and nutmeg. Use a dry measuring cup for the flour and a fine-mesh measuring spoon (like McElroy) for the nutmeg to avoid clumping.

A liquid measuring cup with markings for ¼ cup increments ensures accuracy with the heavy cream and olive oil. For the cheese, a kitchen scale (like OXO Good Grips) guarantees consistent results if you’re substituting cheeses.

Microwave-Safe Bowls

For steaming the broccoli, grab two microwave-safe bowls (I use glass Pyrex) that are large enough to hold 2 cups of florets each. The bowls need to be microwave-safe up to high heat—check the label for compatibility.

A fork or skewer helps pierce the plastic wrap for steam release, and a colander with a fine mesh is crucial for draining excess moisture thoroughly.

Optional Upgrades

For a crispier top, invest in a quiche dish (like Le Creuset Stoneware) that conducts heat differently. A digital thermometer (like ThermoWorks Thermapen) ensures the quiche hits 160°F internally for perfect doneness.

If you love garlic, a garlic press (like OXO) makes mincing those 2 cloves effortless. For storage, airtight containers (like Rubbermaid Brilliance) keep leftovers fresh for days. 💡
