Ingredients You’ll Need
Every ingredient in this Vegetable Crustless Quiche pulls its weight—there’s just enough to make each bite taste vibrant and creamy, and nothing you won’t find at your favorite grocery store. These essentials build everything from the fluffy texture to the irresistible golden top.
- Eggs: The foundation for a classic quiche, eggs provide structure and protein, making every slice satisfying and fluffy.
- Milk or Half-and-Half: Adds gentle richness to the custard; use half-and-half for a slightly creamier texture, or milk for a lighter bite.
- Shredded Cheddar or Swiss Cheese: Choose your cheese based on your mood—cheddar gives a sharp flavor pop, while Swiss is milder and nutty.
- Fresh Spinach: Packs in nutrients and a pretty burst of green; always wilt it before mixing so the quiche bakes up evenly.
- Bell Pepper: For a sweet bite and vivid color—red, orange, or yellow varieties all work beautifully.
- Onion: Brings subtle depth to the savory flavors; chop it small so it mingles well with the other veggies.
- Mushrooms: Their earthy flavor makes the quiche taste heartier and complements the creamy egg base.
- Olive Oil: Sauté the vegetables until just tender with a splash of olive oil—this prevents soggy veggies and adds a hint of richness.
- Garlic Powder: An easy way to infuse comforting flavor throughout the custard without overpowering the veggies.
- Salt and Black Pepper: Key for seasoning—use freshly ground pepper if you like a little extra kick.
- Red Pepper Flakes (optional): For those who adore a gentle hint of heat, just a pinch will do!
How to Make Vegetable Crustless Quiche
Step 1: Preheat and Prep the Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or baking dish with a bit of olive oil or nonstick spray. This keeps your Vegetable Crustless Quiche from sticking, making for easy slicing and serving later on. Prepping the dish first means everything will come together smoothly once the filling is ready.
Step 2: Sauté the Veggies
Heat the olive oil in a skillet over medium heat. Toss in the chopped onions, diced bell peppers, and sliced mushrooms. Sauté these for 4 to 5 minutes, stirring occasionally, until they soften and begin to look glossy and fragrant. Then add the chopped spinach and cook for just another minute—just enough for it to wilt and become vibrant green. This step ensures every vegetable is tender and ready to shine in your quiche.
Step 3: Mix the Egg Custard
In a large mixing bowl, whisk together the eggs, milk (or half-and-half), garlic powder, salt, black pepper, and a pinch of red pepper flakes if you’re feeling spicy. Whisking well now gives your quiche that wonderfully puffy, delicate texture, and helps blend the seasoning evenly throughout.
Step 4: Combine and Pour
Now bring the star flavors together! Stir the sautéed veggies and shredded cheese right into the egg mixture, folding gently until everything is well distributed. Pour the mixture into your prepared baking dish and spread it out evenly—making sure the cheese and veggies are scattered throughout for maximum flavor in every slice.
Step 5: Bake to Golden Perfection
Slide your dish into the oven and bake for 30 to 35 minutes. You’ll know it’s ready when the center is set (give it a wiggle, and it shouldn’t slosh) and the top is just lightly golden. If you like a little crisp on top, leave it in the oven for an extra minute or two, watching closely. Let your Vegetable Crustless Quiche cool for 5 to 10 minutes—it sets up perfectly for easy slicing and serving warm.
How to Serve Vegetable Crustless Quiche

Garnishes
Adding garnishes truly elevates the finished Vegetable Crustless Quiche from simple to spectacular. Fresh herbs like chives, parsley, or basil bring a pop of color and garden-fresh taste. For a little indulgence, try a dollop of sour cream or a sprinkle of extra shredded cheese right before serving. Thinly sliced green onions and a shake of smoked paprika will instantly make your dish brunch-worthy!
Side Dishes
This quiche is delicious all on its own, but balanced sides can turn it into a memorable meal. Pair it with a crisp green salad tossed in a light lemon vinaigrette, or serve with seasoned roasted potatoes for heartiness. Toasted artisan bread, fresh fruit, or even a simple tomato salad all make fantastic, colorful partners for Vegetable Crustless Quiche.
Creative Ways to Present
Let your creativity shine when it comes to presentation! For a brunch party, bake mini Vegetable Crustless Quiches in muffin tins—guests will love the grab-and-go format. You can also cut the quiche into bite-sized squares for a crowd-pleasing appetizer platter. Serve slices on a rustic wooden board with fruit, cheese, and crackers for an Instagram-worthy brunch spread.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, Vegetable Crustless Quiche stores beautifully. Place cooled slices in an airtight container and refrigerate for up to four days. Having a ready-made, protein-rich breakfast or lunch at your fingertips is a real treat on busy days!
Freezing
For longer-term storage, quiche is surprisingly freezer-friendly. After cooling completely, wrap individual slices or the entire pie (tightly covered) in plastic wrap, then foil. Freeze for up to two months. Just remember to label and date before freezing so you’ll know exactly what deliciousness awaits you in the freezer later.
Reheating
To reheat, pop a slice in the microwave for 1 to 2 minutes, or warm in a 350°F (175°C) oven for about 10 minutes until heated through. If reheating from frozen, thaw overnight in the fridge first for the best texture. The quiche holds up beautifully, retaining its fluffy eggs and melty cheese for your next meal.
FAQs
