Ingredients

• 12 large eggs
• 1 cup whole milk (or any plant-based milk for dairy-free)
• 1 ½ cups shredded cheddar cheese (or your favorite cheese)
• 1 cup chopped fresh spinach
• 1 cup diced bell peppers (red, yellow, or green)
• 1 cup sliced mushrooms
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 1 tablespoon olive oil
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon dried thyme
• ¼ teaspoon red pepper flakes (optional for a hint of spice)

Equipment

• Large mixing bowl
• Whisk or electric mixer
• Large skillet for sautéing vegetables
• 9×13-inch baking dish or similar size casserole dish
• Measuring cups and spoons
• Knife and cutting board
• Oven mitts
• Spatula or wooden spoon

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your 9×13-inch baking dish with olive oil or non-stick spray.
2. Prepare the vegetables: Heat olive oil in a large skillet over medium heat. Add chopped onions and sauté for 3-4 minutes until translucent.
3. Add minced garlic, diced bell peppers, and sliced mushrooms. Cook for 5-7 minutes until vegetables are tender and any moisture has evaporated.
4. Stir in fresh spinach and cook for another 2 minutes until wilted. Remove from heat and let cool slightly.
5. In a large mixing bowl, whisk together the eggs and milk until fully combined and slightly frothy.
6. Add salt, black pepper, dried thyme, and red pepper flakes to the egg mixture and whisk again.
7. Fold in the sautéed vegetables and shredded cheese to the egg mixture, stirring gently to combine evenly.
8. Pour the mixture into the prepared baking dish, spreading it out evenly.
9. Bake in the preheated oven for 35-40 minutes or until the quiche is set and the top is lightly golden. A knife inserted in the center should come out clean.
10. Remove from oven and let cool for 10 minutes before slicing and serving.

Tips & Variations

“For a dairy-free option, substitute the cheese with nutritional yeast or omit it altogether, and use almond or soy milk.”

If you want to add more protein, consider folding in cooked lentils or crumbled tofu before baking.

Feel free to swap out the vegetables according to what’s in season or what you prefer—zucchini, broccoli, or cherry tomatoes work wonderfully.

For an extra burst of flavor, sprinkle freshly chopped herbs like basil or parsley on top right before serving.

This quiche also freezes well—cut into portions and freeze in airtight containers for up to 3 months. Reheat in the oven or microwave for a quick meal.
