Today, I’m absolutely delighted to share a recipe close to my heart: a truly delightful Crustless Breakfast Vegetable Quiche. It’s wonderfully savory, packed with garden-fresh goodness, and incredibly satisfying – a true hug in a dish, without the fuss of a pastry crust.
I remember my grandmother, bless her heart, always saying that the best meals are made with love and simple ingredients. She’d whip up the most incredible breakfast spreads, and while she often made a hearty frittata, this quiche reminds me so much of her resourceful spirit and ability to turn everyday vegetables into something extraordinary. Learning from her, and through years of experimenting in my own kitchen, I’ve found that some of the greatest joys come from these humble creations.
This recipe is not only incredibly easy to bake, making it perfect for busy mornings or a relaxed weekend brunch, but it’s also a fantastic way to bring the family together around the table. My top tip for any baker, new or seasoned, is to always trust your senses; the sight, smell, and even the gentle sizzle tell you a story of what’s happening in your oven.

How to Make Crustless Breakfast Vegetable Quiche
Making this delightful Crustless Breakfast Vegetable Quiche is a simple dance of sautéing, whisking, and baking, much like a cherished family tradition. We begin by preparing our oven and dish, then gently sautéing our chosen vegetables until they’re tender and fragrant, releasing all their wonderful flavors.

Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish with butter or cooking spray.
- Heat olive oil in a large skillet over medium heat. Add the diced yellow onion and red bell pepper. Sauté for 3-5 minutes until they begin to soften.
- Add the sliced cremini mushrooms and minced garlic to the skillet. Cook for another 3-4 minutes, stirring occasionally, until the mushrooms are tender and have released most of their liquid.
- Stir in the roughly chopped fresh spinach. Cook for 1-2 minutes until the spinach wilts down. Remove the skillet from the heat and let the vegetables cool slightly.
- In a large mixing bowl, whisk together the large eggs, whole milk (or half-and-half), salt, black pepper, and ground nutmeg until the mixture is smooth and well combined.
- Stir in the shredded sharp cheddar cheese and the sautéed, cooled vegetable mixture into the egg mixture. Mix gently to distribute the ingredients evenly.
- Pour the entire quiche mixture evenly into the prepared 9-inch pie dish.
- Bake for 40-45 minutes, or until the center of the quiche is set (it shouldn’t jiggle much when gently shaken) and a knife inserted near the center comes out clean. The top should be lightly golden brown.
- Remove the quiche from the oven and let it cool for 5-10 minutes before slicing and serving. This resting time helps the quiche set completely and makes for cleaner slices.
Notes
Pro Tips for Making This Crustless Breakfast Vegetable Quiche
I’ve learned a thing or two over the years about getting that perfect quiche texture, and I’m so happy to share my little secrets for perfecting your Crustless Breakfast Vegetable Quiche. These tips will ensure your quiche is tender, flavorful, and a true delight every time.
My Secret Trick: I always make sure to really press out as much moisture as possible from the cooked spinach before adding it to the egg mixture. This prevents your quiche from becoming watery and ensures a beautifully firm set.
Don’t overcrowd your pan when sautéing the vegetables. Give them enough space to brown nicely; this caramelization adds a depth of flavor that really makes the quiche sing. If your pan is too full, the vegetables will steam instead of getting that lovely browning.
When whisking the eggs and milk, make sure to do it thoroughly until the mixture is light and frothy. This incorporates air, which helps the quiche become wonderfully fluffy and airy, just the way I adore it.
Remember, every oven is a little different! Keep an eye on your quiche in the last 10-15 minutes of baking. It’s ready when the center is just set, and a knife inserted comes out clean. A slight wobble in the very middle is perfectly fine, as it will continue to cook as it cools.
Fun Variations for Crustless Breakfast Vegetable Quiche
The beauty of a Crustless Breakfast Vegetable Quiche is how wonderfully adaptable it is! It’s like a blank canvas just waiting for your creative touch. Here are a few ways my friends and I love to change things up:
Seasonal Swaps
Feel free to swap out the vegetables based on what’s fresh and in season! Asparagus and green onions are lovely in the spring, while diced zucchini and cherry tomatoes make a fantastic summer twist. My sister always asks me to add a handful of roasted butternut squash in the fall for a touch of sweetness.
Herb & Spice Adventures
Play with different herbs! Fresh dill or chives can add a bright, fresh note. A pinch of smoked paprika or a dash of red pepper flakes can introduce a subtle warmth and gentle kick, perfect for those who enjoy a little spice.
Cheese, Please!
While sharp cheddar is a classic, don’t hesitate to experiment with other cheeses. Gruyere offers a nutty richness, while a touch of feta can provide a delightful tanginess. A friend loves when I sprinkle a little Parmesan on top for a crispy, golden crust.
What to Serve With Crustless Breakfast Vegetable Quiche
A delicious Crustless Breakfast Vegetable Quiche is a star on its own, but it truly shines when paired with a few simple accompaniments that complete the meal. These are the touches that make a breakfast or brunch feel extra special:
I love serving this quiche with a vibrant, fresh fruit salad. The crisp sweetness of berries, melon, and grapes offers a wonderful contrast to the savory richness of the quiche, making each bite a delightful experience. It’s light, refreshing, and adds a beautiful splash of color to your table.
For something a little heartier, a side of crispy bacon or breakfast sausage is always a hit in my home. The salty crunch complements the soft, custardy texture of the quiche beautifully. Alternatively, a simple green salad with a light vinaigrette can be a lovely and easy option, especially for a lunch pairing.
And of course, no breakfast is complete without a warm cup of coffee or a comforting mug of hot tea. My mom always pairs her quiche with a strong cup of English breakfast tea, saying it balances the richness perfectly.
How to Store Crustless Breakfast Vegetable Quiche
To ensure your delightful crustless breakfast vegetable quiche stays as fresh and delicious as possible, proper storage is key! After it has cooled completely, you can store any leftovers in an airtight container in the refrigerator for up to 3-4 days.
Reheating Wonders
When you’re ready to enjoy a slice again, I recommend reheating it gently. For a single slice, a quick zap in the microwave for 30-60 seconds usually does the trick, but if you prefer a slightly crisper texture, pop it in a preheated oven at 300°F (150°C) for about 10-15 minutes. My personal tip for reheating is to cover it loosely with foil if using the oven; this prevents it from drying out.
Freezer Friendly
Yes, this quiche freezes beautifully! Wrap individual slices tightly in plastic wrap, then again in aluminum foil, and store them in a freezer-safe bag or container for up to 2-3 months. Thaw overnight in the fridge before reheating.
Nutritional Benefits
This crustless breakfast vegetable quiche is a wonderful way to enjoy a satisfying meal that’s both nourishing and full of flavor. Packed with protein from the eggs and milk, and a generous helping of fiber and vitamins from the colorful array of vegetables like spinach, bell peppers, and mushrooms, it’s a treat that’s both satisfying and wholesome. It truly reflects my belief that delicious food can also be good for you!
