Breakfast & Brunch
This 8-egg crustless quiche recipe delivers a high-protein breakfast that bakes up golden and fluffy in just 30 minutes—no crust, no fuss, all flavor. The secret lies in whisking eggs to ribbons and baking at the right temperature to create that signature custardy center with crispy edges.
I developed this recipe for busy mornings when I needed a meal that was both nutritious and foolproof.
What makes this quiche special is its versatility—you can customize it with vegetables, cheese, or proteins like bacon while keeping the same perfect texture. The eggs provide a rich, creamy base that holds fillings beautifully, and the lack of crust means every bite is pure, unadulterated flavor.
This recipe is ideal for meal prep too, as it reheats well and stays fresh in the fridge for up to 4 days.
By the time it emerges from the oven, you'll have a quiche with a golden top, tender fillings, and a silky-smooth custard that's impossible to resist. The high-protein content makes it satisfying enough for breakfast or brunch, and the one-pan method ensures minimal cleanup.
Whether you're feeding a family or meal prepping for the week, this recipe delivers restaurant-quality results without the effort.
For best results, let the quiche rest for 10 minutes before slicing—this allows the custard to set properly. Serve warm with a side salad or fresh fruit for a balanced meal. The possibilities for fillings are endless, so feel free to experiment with your favorites. Let's get started!
Ingredients for 8 egg crustless quiche
Eight eggs plus simple vegetables create a protein-packed quiche with golden edges and creamy custard.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 8 whole | Room temperature for even baking |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for rich texture |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Sharp variety preferred |
| Fresh Spinach 🌿 | 2 cups | Chopped, stems removed |
| Red Bell Pepper 🍅 | 1 whole | Diced, seeds removed |
| Yellow Onion 🧅 | 1 whole | Finely diced |
| Garlic Cloves 🧄 | 3 cloves | Minced |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Dried Thyme 🌿 | ¼ tsp | Or 1 tbsp fresh |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For greasing pan |
| Vegetable Broth 💧 | ½ cup | Low-sodium preferred |
Eggs are the foundation—room temperature ensures even cooking. Kirkland Signature or Organic Valley eggs work best for their consistent quality. The heavy cream adds richness, so don't substitute with anything lighter. For the cheese, sharp cheddar melts beautifully, but Gruyère adds an extra layer of flavor if you want to splurge. Fresh spinach wilts quickly, so chop it just before adding to the egg mixture—no need to drain it, the moisture will cook off. The bell pepper and onion can be prepped ahead and stored in the fridge for 3 days.
No heavy cream? Full-fat Greek yogurt works in a pinch, though the texture will differ slightly. Substitute sharp cheddar with Parmesan for a tangier flavor. If you prefer milder vegetables, swap the spinach for zucchini or mushrooms. The thyme can be omitted if you dislike its earthy note, but it adds depth that's worth keeping. For extra protein, consider adding crumbled feta or goat cheese—both hold up well during baking. The vegetable broth adds moisture without overpowering the egg base, so if you're using a low-sodium version, you might want to add a pinch of salt to the egg mixture separately.
This quiche is best served immediately, but it reheats beautifully in the microwave for 30 seconds if needed. Store leftovers in an airtight container in the fridge for up to 4 days, though I find it's at its best within 2 days. For meal prep, portion into individual containers—the custard texture holds up well when reheated. Freezing isn't recommended as the texture can become grainy, but you can freeze the filling mixture separately for 3 months if you prefer to bake fresh each time.
Why You'll Love This Recipe
- No-Crust Nightmare: I’ll admit it—this is the only quiche I make when I’m too tired for pie crust. Eight eggs? That’s a lot of protein-packed richness without the fuss of rolling dough. Just chop, mix, and bake—no one will guess it’s this simple.
- Cheese-Spinach Magic: Between us, that sharp cheddar and wilted spinach combo is ridiculously good. The red bell pepper adds just enough sweet crunch to balance the creaminess, and honestly? The first bite makes me wonder why I ever bothered with crust.
- Lunchbox Hero: I swear by this for meal prep—slice it up, pack it with whole wheat toast, and boom, you’ve got a lunch that’s filling, portable, and won’t turn to sad soggy bread by noon. (Yes, even on a Tuesday night.)
- Budget Breakfast Club: Eight eggs for one pan? That’s my secret weapon for stretching groceries. The heavy cream makes it feel indulgent, but the cost per serving is shockingly reasonable. Leftovers last four days in my fridge—no waste, all flavor.
Step-by-step instructions for high-protein crustless quiche
Here's how to assemble this protein-packed quiche in under 30 minutes of active time.
Prep and Sauté the Vegetable Base
Heat the 0.25 cup extra-virgin olive oil in a 10-inch oven-safe skillet over medium heat. Add the 1 whole yellow onion and 1 whole red bell pepper, diced into ¼-inch pieces. Cook for 5-6 minutes until softened and slightly caramelized at the edges.
Add the 2 cups fresh spinach, 3 cloves minced garlic, 0.25 tsp dried thyme, 0.5 tsp salt, and 0.25 tsp ground black pepper. Stir continuously for 2-3 minutes until the spinach wilts completely and the garlic becomes fragrant. Remove from heat and set aside—this base should be just warm, not hot, when we mix it with the eggs.
Whisk the Egg and Cream Mixture
In a large bowl, whisk together the 8 whole large eggs and 1 cup heavy whipping cream until fully combined and slightly frothy. This ensures an even distribution of fat throughout the quiche for a rich, creamy texture.
Gradually whisk in the 1.5 cups shredded cheddar cheese until fully melted and smooth. The mixture should be thick but pourable. I like to strain it through a fine-mesh sieve at this point to remove any lumps—this prevents graininess in the final quiche. Taste and adjust seasoning if needed, though the cheese and broth should provide ample flavor.
Combine and Bake for Golden Perfection
Return the skillet to medium-low heat and pour in the 0.5 cup vegetable broth. Stir to combine with the vegetable mixture, then remove from heat. Immediately pour the egg mixture evenly over the vegetable-broth mixture, stirring gently to distribute everything.
Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes. The quiche is done when the top is golden brown, the edges are set, and the center still has a slight wobble—it'll firm up as it cools. Avoid overbaking, which can make the quiche dry. The internal temperature should reach 160°F at its thickest point.
Rest and Serve Warm
Remove the quiche from the oven and let it rest for 5-10 minutes before serving. This resting time allows the custard to set properly and prevents any potential collapse when cutting. The quiche should be slightly jiggly in the center but firm around the edges.
Slice into 6 equal wedges and serve immediately. The combination of creamy eggs, sharp cheddar, and wilted vegetables creates a balanced, protein-rich breakfast that holds together beautifully. Store leftovers in the refrigerator for up to 3 days—reheat gently in the oven or microwave to maintain texture.
Pro Tips For Making 8 Egg Crustless Quiche
- PREHEAT TO 375°F—NO EXCUSES: I learned this the hard way—starting at 350°F means your quiche will sit in the oven like a sad, lukewarm science experiment while the top sets unevenly. Crank the oven to 375°F and let it scream hot for 15 minutes before baking. The eggs need that initial shock to set fast and even, especially with all that cream making them rich and heavy.
- SALT THE EGGS FIRST: Skip the "taste as you go" guesswork—whisk the eggs and cream together, then season with 1½ teaspoons salt (yes, that much) right away. The spinach and cheese will add their own saltiness later, but the eggs need that upfront punch to balance the whole dish. Trust me, your quiche will thank you when it’s not bland.
- DRAIN AND PRESS THE SPINACH: Fresh spinach is 90% water, and soggy quiche is no one’s idea of a good time. After wilting the spinach in a pan (or microwaving it), squeeze out every last drop with a clean kitchen towel or paper towels. Pack it into the dish tightly—this keeps the filling firm and prevents a watery mess when the eggs cook.
- USE A WATER BATH FOR EVEN COOKING: This isn’t the prettiest method, but it’s the tastiest. After pouring the egg mixture into your dish, place it in a larger baking dish and fill the gap with hot water halfway up the sides. The steam ensures the center cooks without rubberizing, especially with 8 eggs. Remove the water after 20 minutes, then finish uncovered—your quiche will set like a dream.
Storing and reheating your 8 egg crustless quiche
Fridge Storage Tips
Let your quiche cool completely before storing to prevent condensation, which can make it soggy. Transfer to an airtight container (I love Glasslock containers) and refrigerate for up to 4 days.
The custard texture actually improves overnight as flavors meld together. Label with the date—trust me, you'll forget otherwise! 📅
Microwave Reheating
For quick servings, slice a piece and reheat in the microwave for 30-45 seconds on 50% power. Cover loosely with a damp paper towel to prevent drying.
If it looks dry, add 1 teaspoon of milk or water and reheat for another 10 seconds. This method works best for single servings.
Oven Reheating
For best texture, reheat the whole quiche in a 350°F oven for 10-15 minutes covered with foil. Remove foil for the last 2 minutes to crisp the top.
This method is perfect when serving multiple people or for meal prep portions. The edges stay crispy while the center remains creamy. 🔥
Freezing Limitations
Unfortunately, this quiche doesn't freeze well—the custard can become grainy. However, you can freeze the unbaked filling mixture (eggs, cream, and cheese) separately for 3 months. Thaw overnight in the fridge before baking fresh. This is a great trick for busy mornings!
Meal Prep Strategy
Divide cooled quiche into 6 individual portions using a pizza cutter for clean slices. Store in single-serving containers with tight lids. Reheat each portion as needed—this keeps your quiche fresh and ready for grab-and-go breakfasts all week. I pack mine with a side of fruit for a balanced meal. ✨

Frequently asked questions
Why does my crustless quiche come out rubbery?
Overmixing the eggs or overbaking are the most common culprits. Whisk just until combined (no ribbons needed) and bake at 375°F for 20-25 minutes—the center should jiggle slightly. For extra creaminess, use full-fat cream instead of milk, and avoid opening the oven door during baking.
Can I make this quiche ahead for meal prep?
Bake it fresh and store in an airtight container for up to 4 days. Reheat single slices in the microwave (30-45 seconds) or warm the whole quiche in a 350°F oven for 10 minutes covered with foil. The texture holds up beautifully when reheated properly.
What's the best pan for this recipe?
A 10-inch oven-safe skillet works perfectly—cast iron or stainless steel conducts heat evenly. Avoid nonstick pans if you want that classic golden crust. If your pan is smaller, reduce the vegetable filling by ¼ cup to maintain proper proportions.
How do I adjust this for fewer eggs?
For a 6-egg version, reduce all other ingredients by 25% (including cheese and cream). The baking time stays the same, but check for doneness at 18 minutes. For best texture, keep the pan size consistent—use a 9-inch skillet instead of reducing the pan size.
Can I add cooked bacon or sausage?
Yes! Drain and pat dry ½ cup cooked bacon or sausage first, then mix it into the sautéed vegetables. For a heartier quiche, add ¼ cup extra cheese to balance the added fat. Just be sure to remove the pan from heat before adding the egg mixture to prevent scrambling.
