How to make it healthier?

  • Cut back on sodium: Try using low-sodium butter, cheese, and salt options. Alternatively, use herbs and spices to amplify flavors instead of relying solely on salt.
  • Add more vegetables: Incorporate extra veggies like diced bell peppers or mushrooms into the spinach filling. This adds flavor and texture and packs in more fiber and nutrients.

Time-saving tips

  • Use pre-shredded cheese: Purchase pre-shredded cheese instead of grating it yourself to save a few extra minutes.
  • Use pre-chopped vegetables: Opt for pre-chopped frozen spinach and onions if you’re in a rush. This will eliminate prep time and cut down on cleaning.

What can I prepare ahead of time?

  • Prepare the crust: Prepare the crust mixture and press it into the pie dish as instructed. Then, partially bake the crust for 15 minutes, let it cool down, wrap it in plastic and store it in the refrigerator for later use.

Storage and reheating instructions

Storage tips

  • Refrigerator: Allow the quiche to cool completely before storing to prevent condensation. Store it in an airtight container or wrap it tightly with plastic wrap to keep it fresh. Refrigerate it for up to 3-4 days for optimal freshness.
  • Freezer: If you plan to freeze a batch, wrap it in aluminum foil or plastic wrap and consume it within 2-3 months for the best quality. 

Reheating best practices

  • Microwave: To reheat the spinach quiche in the microwave, place a slice on a microwave-safe plate and heat on medium power for 1-2 minutes until warm. Let it rest for a few minutes before serving.
  • Oven: Put the leftovers on a baking sheet in the preheated oven at 325°F (160°C). Cover them with foil and heat for 10-15 minutes until heated properly.

The almond flour and coconut flour combination works best for a low-carb crust. However, you can experiment with other low-carb options.
