Ingredients Overview
Here’s what makes this veggie-packed quiche both flavorful and practical:
-
Eggs: The base of the quiche — they provide protein and structure. Use large eggs for the best results.
-
Milk (dairy or non-dairy): Helps create the light, custardy texture. Whole milk gives richness; almond, oat, or soy milk keep it dairy-free.
-
Cheese (cheddar, Swiss, feta, or goat cheese): Adds flavor and creaminess. Use your favorite or a combination for variety.
-
Vegetables: A mix of fresh or frozen vegetables adds color, nutrients, and texture. Popular choices include:
-
Spinach (fresh or frozen)
-
Bell peppers
-
Broccoli
-
Mushrooms
-
Zucchini
-
Onions
-
-
Salt, pepper & herbs: Garlic powder, thyme, parsley, or basil elevate the flavor. Fresh herbs are ideal but dried work well too.
Ingredient Tips & Substitutions
-
Gluten-free: Naturally gluten-free — no crust needed.
-
Dairy-free: Use plant-based milk and omit cheese or use dairy-free cheese alternatives.
-
Add protein: Add chopped turkey bacon, cooked sausage, or tofu for an extra protein boost.
-
Veggie prep: Lightly sauté watery vegetables like mushrooms or zucchini before adding them to avoid excess moisture.
This recipe is forgiving — you can swap ingredients based on your taste or fridge contents.
Step-by-Step Instructions
-
Preheat oven to 375°F (190°C).
Lightly grease a 9-inch pie dish or round baking dish with oil or cooking spray. -
Sauté vegetables (if needed).
If using raw mushrooms, spinach, onions, or zucchini, sauté them briefly in a pan with a touch of oil to release excess water. Let cool slightly. -
Whisk the egg mixture.
In a large bowl, whisk together:-
6 large eggs
-
½ cup milk (dairy or non-dairy)
-
½ tsp salt
-
¼ tsp black pepper
-
½ tsp garlic powder or dried herbs (thyme, basil, etc.)
-
-
Assemble the quiche.
Add to the greased pie dish:-
1–1½ cups chopped vegetables (cooked or raw as needed)
-
¾ cup shredded cheese of choice
Pour the egg mixture over the top and gently mix with a fork or spoon to distribute evenly.
-
-
Bake.
Bake for 35–40 minutes, or until the quiche is set in the center and lightly golden on top. A knife inserted into the center should come out clean. -
Cool and serve.
Let cool for 10 minutes before slicing. Serve warm, at room temperature, or chilled.
The texture will be tender and custardy, with each slice full of colorful veggies and pockets of melty cheese.
