How to Make Perfect Cauliflower & Spinach Quiche Recipe
Step 1: Prepare Your Oven and Pie Crust
Begin by preheating your oven to 375°F (190°C) to ensure it’s hot when your quiche is ready to bake. Carefully place your pie crust into a 9-inch pie dish, pressing it snugly against the edges. You can use a store-bought crust for convenience or homemade if you want that extra homemade touch—it works wonderfully either way.
Step 2: Sauté Your Vegetables
Heat olive oil in a skillet over medium heat. Toss in the diced onion and cook it gently for 2 to 3 minutes until it softens and releases its natural sweetness. Next, add the cauliflower florets and sauté for 6 to 8 minutes until they turn tender but still maintain a slight bite. Finally, stir in the spinach and cook for another 1 to 2 minutes until it wilts beautifully. This sautéed mix brings out the best flavors and ensures no raw crunch will surprise you after baking.
Step 3: Whisk Together the Custard Filling
In a large mixing bowl, whisk the eggs, whole milk, heavy cream, nutmeg, salt, and black pepper until well combined. This rich custard mixture will soak into the vegetables and cheese, creating a luxurious filling. Fold in the shredded Swiss cheese or Gruyère for that lovely nutty flavor and irresistible melt.
Step 4: Assemble Your Quiche
Spread the warm sautéed vegetables evenly across the bottom of the pie crust. Then, carefully pour the custard and cheese mixture over the top, allowing it to seep into every little nook and cranny. This layering ensures you get a perfect balance of veggies and creamy filling in every bite.
Step 5: Bake to Perfection
Pop your quiche into the preheated oven and bake for 40 to 45 minutes. You’ll know it’s done when the center is just set and the top has taken on a lovely, light golden hue. Let it rest for 10 minutes after removing it from the oven—this helps with slicing and improves the flavor as the quiche settles.
