What Makes This Special

• Almond flour crust gives a buttery flavor and a delicate texture without using wheat flour.
• Flexible filling: swap in whatever vegetables you have on hand, from spinach to peppers.
• Meal-prep friendly: holds up well for a few days and reheats nicely.
• Balanced and satisfying without feeling heavy, thanks to the veggie-forward filling.

Ingredients

• For the crust:
  • 2 cups fine almond flour
  • 1 large egg
  • 3 tablespoons melted unsalted butter or olive oil
  • 1/2 teaspoon fine sea salt
  • 1/4 teaspoon garlic powder (optional)
• For the filling:
  • 1 tablespoon olive oil
  • 1 small yellow onion, finely chopped
  • 1 red bell pepper, diced
  • 1 small zucchini, diced
  • 2 cups baby spinach, roughly chopped
  • 4 large eggs
  • 3/4 cup milk or half-and-half
  • 1/2 cup grated cheese (Gruyère, cheddar, or feta crumbles all work)
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon smoked paprika or dried thyme

How to Make It

1. Heat the oven to 350°F (175°C). Lightly grease a 9-inch pie dish.
2. Make the crust: In a bowl, combine almond flour, salt, and garlic powder.Stir in the egg and melted butter until a dough forms. It should feel slightly sticky but workable.
3. Press and par-bake: Press the dough evenly into the pie dish, pushing it up the sides. Prick the bottom with a fork.Bake for 10–12 minutes until just set and lightly golden at the edges. Let it cool slightly.
4. Sauté vegetables: Warm the olive oil in a skillet over medium heat. Cook onion and bell pepper for 4–5 minutes until softened.Add zucchini and cook 3 more minutes. Stir in spinach just until wilted. Remove from heat and let excess moisture evaporate.
5. Whisk the custard: In a bowl, whisk eggs, milk, salt, pepper, and paprika or thyme.Stir in the cheese.
6. Assemble: Spread the cooked vegetables evenly over the crust. Pour the egg mixture on top, tilting the dish to distribute.
7. Bake for 28–35 minutes, until the center is set and the top is lightly golden. A slight wobble is fine; it will finish setting as it cools.
8. Rest and slice: Let the quiche stand for 10–15 minutes before slicing for the cleanest cuts.

Keeping It Fresh

• Refrigerate leftovers in an airtight container for up to 4 days.
• Reheat slices at 300°F (150°C) for 10–12 minutes, or microwave in short bursts.
• Freeze whole or sliced, tightly wrapped, for up to 2 months.Thaw overnight in the fridge, then warm in the oven.

Benefits of This Recipe

• Gluten-free friendly without sacrificing taste or texture.
• Vegetable-rich breakfast, lunch, or light dinner option.
• Customizable: use seasonal produce and your favorite cheese.
• Make-ahead: perfect for hosting or easy weekday meals.

Common Mistakes to Avoid

• Skipping the par-bake: The crust needs that head start to avoid sogginess.
• Too much moisture: Don’t add watery vegetables (like zucchini or mushrooms) without sautéing them first.
• Overbaking: Pull it when the center is just set. Overbaking leads to a rubbery texture.
• Uneven crust: Press the dough evenly up the sides so the filling doesn’t spill and bake unevenly.

Alternatives

• Dairy-free: Use olive oil in the crust, dairy-free milk, and skip the cheese or use a plant-based cheese.
• Protein boost: Add cooked turkey bacon, chicken sausage, or smoked salmon.
• Veggie swaps: Try mushrooms, asparagus, cherry tomatoes, or kale. Just cook off extra moisture first.
• Flavor twists: Swap paprika for Italian herbs, add a pinch of nutmeg, or sprinkle feta and olives for a Mediterranean vibe.

FAQ

Can I make the crust ahead of time?

Yes. Par-bake the crust, let it cool, then cover and refrigerate for up to 24 hours. Fill and bake when ready.

What if I don’t have almond flour?

You can try a store-bought gluten-free pie crust or a traditional pastry crust. Note that the flavor and texture will change, but the filling works with either.

How do I prevent a soggy bottom?

Par-bake the crust, sauté moisture-heavy vegetables, and let them cool slightly before adding the custard. Avoid overfilling.

Can I use egg whites only?

You can, but the quiche will be less rich. Use 6–7 egg whites to replace 4 whole eggs and consider adding a splash more milk for tenderness.

What size pan works best?

A 9-inch pie dish or tart pan is ideal. If using a deeper dish, add a few extra minutes to the bake time.
