Ingredients Overview

This quiche keeps things simple with wholesome, colorful ingredients that bake beautifully together.

Eggs
The base of the quiche, eggs provide structure and protein while staying light and fluffy. Use large eggs—typically 6 to 8 depending on pan size.

Milk or Half-and-Half
Adds creaminess and moisture. Use whole milk for a lighter texture, or half-and-half for a richer finish. Dairy-free milk like unsweetened almond or oat milk also works.

Cheese
Shredded cheddar, Swiss, feta, or goat cheese all melt well and bring savory depth. Choose your favorite or mix for more flavor.

Broccoli
Chopped into small florets, broccoli adds bulk and mild, nutty flavor. Steam lightly beforehand for best texture.

Bell Peppers
Red, yellow, or orange peppers bring sweetness and vibrant color. Dice finely so they cook evenly in the quiche.

Spinach
Adds an earthy, leafy green element. Sauté or thaw and drain frozen spinach to remove moisture before adding.

Onion or Green Onion
Aromatic base flavor that enhances the quiche without overpowering it. Red onion or scallions add color and a mild bite.

Salt, Pepper, Garlic Powder
Essential seasonings that keep the flavor balanced and savory.

Olive Oil or Butter (Optional)
Used to sauté veggies before baking for better flavor and moisture control.

Step-by-Step Instructions

1. Preheat Oven and Prep Pan (5 minutes)
Preheat oven to 375°F. Lightly grease a 9-inch pie dish or 8×8-inch baking dish with olive oil or nonstick spray.

2. Sauté the Vegetables (5–7 minutes)
In a skillet over medium heat, add a drizzle of olive oil. Sauté onion for 2–3 minutes until softened. Add bell pepper and broccoli, and cook another 3–4 minutes until just tender. Stir in spinach and cook until wilted. Season with salt, pepper, and garlic powder. Remove from heat and let cool slightly.

3. Mix Eggs and Dairy (2 minutes)
In a large bowl, whisk together 6 large eggs and ½ cup milk or half-and-half until smooth. Stir in 1 cup shredded cheese and the cooled vegetables.

4. Pour and Bake (35–40 minutes)
Pour the egg mixture into your greased baking dish. Spread evenly. Top with extra cheese if desired.

Bake for 35–40 minutes or until the center is set and the top is golden. A knife inserted should come out clean.

5. Rest and Slice (10 minutes)
Let the quiche rest for 10 minutes before slicing. This allows it to firm up for clean slices and better texture.

Serve warm, room temperature, or chilled—this quiche is delicious any way you enjoy it.
