Ingredients for 8 egg crustless quiche
Eight eggs, creamy richness, and zero crust—just the essentials for this velvety quiche masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 8 whole | Room temperature for even cooking |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for richest texture |
| Whole Milk 🥛 | ½ cup | Warmed slightly for smooth blend |
| Shredded Sharp Cheddar Cheese 🧀 | 1 ½ cups | Freshly grated preferred |
| Yellow Onion 🧅 | 1 whole | Diced into 1/4-inch pieces |
| Garlic Cloves 🧄 | 3 cloves | Minced for even distribution |
| Fresh Spinach 🌿 | 2 cups | Chopped, stems removed |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Nutmeg 🌿 | ¼ tsp | Freshly grated for warmth |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening custard |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For greasing baking dish |
The eggs are non-negotiable here—room temperature is key for even cooking and that signature custardy texture. Kirkland Signature or Vital Farms eggs have the best consistency for this recipe, but any large eggs work. Freshness matters: if your eggs are older than three weeks, whisk them slightly longer to ensure proper emulsification. The heavy whipping cream and whole milk create that restaurant-quality richness—full-fat versions only, no substitutions here. For the cheese, Cabot or Pepper Ridge sharp cheddar melts beautifully without turning rubbery.
No fresh spinach? Frozen works perfectly—thaw and drain thoroughly before chopping. The onion and garlic can be swapped for leeks or shallots if you prefer a milder flavor. Running short on nutmeg? Mace or a pinch of cinnamon adds warmth in a pinch. For a gluten-free version, replace the flour with cornstarch or arrowroot powder at the same ratio. The olive oil should be high-quality extra-virgin—it’s what gives the golden top its subtle crunch without crust.
This quiche bakes best in a 9-inch glass pie dish—it develops that perfect golden top there. Store leftovers covered in the fridge for 4 days or freeze portions for 3 months. Reheat gently in the oven at 325°F until warmed through—microwaving makes it rubbery. For meal prep, assemble the filling and refrigerate overnight before baking—it bakes faster and more evenly. The golden top stays crisp for 24 hours if stored properly, so make it ahead for brunch crowds.

Step-by-step instructions for crustless quiche
Master this technique and you’ll achieve a silky, golden quiche with perfect texture every time.
Sauté Aromatics for Flavor Foundation
Heat the 1 tablespoon extra-virgin olive oil in a 9-inch oven-safe skillet over medium heat. Add the diced yellow onion and cook for 5-6 minutes until softened and translucent. This gentle cooking removes sharpness while building flavor.
Add the 3 cloves minced garlic and cook for another 30 seconds until fragrant. Remove the skillet from heat and stir in the 2 cups chopped fresh spinach, letting it wilt completely. The spinach should reduce to about ½ cup of tender greens when finished.
Whisk Egg Mixture for Perfect Texture
In a large bowl, whisk together the 8 whole large eggs until no streaks remain. Add the 1 cup heavy whipping cream, ½ cup whole milk, 2 tablespoons all-purpose flour, 1 teaspoon salt, ½ teaspoon black pepper, and ¼ teaspoon nutmeg. Whisk vigorously for 1 minute until fully combined and slightly thickened.
This step creates the custard base. The flour acts as a natural thickener, while the warm milk helps create a smoother texture. The eggs should be at room temperature for even cooking throughout.
Combine Filling and Cheese
Return the skillet to medium-low heat and sprinkle evenly with the 1½ cups shredded sharp cheddar cheese. Pour the egg mixture over the spinach and cheese, stirring gently to distribute everything evenly. The mixture should coat the bottom of the skillet completely.
Let the quiche sit undisturbed for 2-3 minutes to allow the cheese to begin melting and the eggs to start setting slightly at the edges. This prevents large cheese clumps and ensures even cooking later.
Bake to Golden Perfection
Preheat your oven to 350°F. Place the skillet in the center rack and bake for 30-35 minutes until the top is golden brown and the center is just set (it should still have a slight wobble). The edges should be fully set while the center remains custardy.
For best results, avoid opening the oven door during baking. The quiche is done when it pulls away slightly from the edges and reaches an internal temperature of 160°F in the center. Let it rest for 10 minutes before serving to allow the custard to fully set.
Serve Warm with Fresh Herbs
Slice the quiche into 8 wedges and serve immediately. Garnish with additional freshly ground black pepper and a sprinkle of freshly grated nutmeg for brightness. The texture should be silky in the center with a golden, slightly crisp top.
This quiche holds well at room temperature for 2 hours and can be reheated gently for 30 seconds in the microwave. The flavor improves as it sits, with the cheese becoming more mellow and the custard developing deeper richness.
Pro Tips For Making 8 Egg Crustless Quiche
- Prep Onions Like a Pro: Slice those yellow onions paper-thin—no thick chunks—so they soften evenly without turning to mush. I learned this the hard way after serving a quiche with chewy onion bits that ruined the texture.
- Whisk Eggs Until Silky: Beat those 8 eggs with a fork or whisk until the yolks and whites blend completely—no streaks. This ensures a smooth, creamy texture instead of a lumpy mess, especially when mixing in the cream and milk.
- Salt the Cheese First: Toss the shredded cheddar with a pinch of salt before folding it into the egg mixture. Sharp cheddar can be inconsistent in saltiness, and this guarantees every bite has the right balance.
- Bake at 350°F, Not Hotter: Skip the urge to crank the oven higher—350°F is the sweet spot for even cooking without a rubbery top. I used to rush it at 375°F and ended up with a quiche that was set outside but still gooey inside.
Flavor customization for these flavors
Classic Cheese Variations
Swap the sharp cheddar for Gruyère (1½ cups) for a nutty, caramelized flavor that melts into a creamy sauce. I love adding 1 cup fontina too—it creates pockets of gooey goodness. For a smoky twist, try smoked Gouda (1 cup) with a pinch of paprika for depth. 🧀
Vegetable Swaps
Replace spinach with sun-dried tomatoes (½ cup, chopped) for a Mediterranean vibe—add them to the egg mixture instead of sautéing. Or try roasted red peppers (½ cup, diced) for natural sweetness. For heartier texture, add diced mushrooms (1 cup) cooked with the onions.
Protein Additions
Boost protein by stirring in ½ cup cooked bacon crumbles or crumbled sausage (like kielbasa) with the cheese. For a lighter option, add ¼ cup crumbled feta after baking. I also love whipped goat cheese (2 tbsp) folded into the egg mixture for tangy brightness.
Spice Infusions
Add ½ teaspoon smoked paprika to the egg mixture for warmth, or sprinkle 1 teaspoon dried thyme over the top before baking. For a zesty kick, mix 1 tablespoon lemon zest into the egg mixture. A pinch of cayenne pepper (¼ tsp) adds subtle heat without overpowering.
Dairy-Free Options
Replace heavy cream with full-fat coconut milkstrong> (1 cup) and whole milk with unsweetened almond milk (½ cup). Use nutritional yeaststrong> (2 tbsp) instead of cheese for a cheesy flavor. For binding, add 1 tbsp cornstarch**strong> to the egg mixture. The texture stays rich but lighter.

Frequently asked questions
Why does my crustless quiche turn out rubbery?
Overbaking is the #1 culprit! Remove it when the center still has a slight wobble (around 160°F internal temp). The custard should be set but still creamy. Also, ensure your eggs are at room temperature and whisked until ribbons form—this prevents uneven cooking. For extra insurance, cover loosely with foil after 20 minutes to slow the top from browning too fast.
Can I make this quiche ahead of time?
Assemble the filling (without baking) and refrigerate overnight—it bakes faster and more evenly. For best results, bake it 24 hours ahead and reheat gently at 325°F for 10-15 minutes. The flavor actually improves as it sits, with the cheese mellowing and custard deepening. Store leftovers covered in the fridge for 4 days or freeze portions for 3 months.
What’s the secret to a golden top without crust?
The golden top comes from three things: 350°F heat, heavy cream, and a 10-minute rest after baking. The cream adds fat for browning, while resting lets the custard set properly. For extra shine, sprinkle a pinch of paprika or nutmeg on top before baking. Avoid opening the oven door during the last 15 minutes—temperature drops cause uneven browning.
Can I use this recipe for a gluten-free version?
Yes! Simply replace the 2 tbsp all-purpose flour with 2 tbsp cornstarch or arrowroot powder. The texture stays creamy since these starches thicken without gluten. For extra binding, whisk the egg mixture for 2 minutes to ensure proper emulsification. The gluten-free version holds up just as well for baking ahead or freezing.
How do I prevent cheese from sinking to the bottom?
Cheese sinking happens when it melts too fast. The fix: Sprinkle cheese evenly over the sautéed veggies, then pour the egg mixture over it—this traps the cheese in place. For extra stability, let the quiche sit undisturbed for 2-3 minutes before baking. If using a very soft cheese (like goat cheese), stir it into the egg mixture instead of sprinkling on top.
