A Nutritious Gluten-Free Twist on a Classic
Forget ordinary quiche—this Sweet Potato Quiche Florentine is a delightful twist that will elevate your brunch game! Inspired by my viral Crushed Potato Pie recipe, this quiche emerged from numerous comments and DMs asking if a sweet potato base was possible. The result is delicious! Just a quick tip: because sweet potatoes have a higher water content than regular potatoes, the edges of the base can shrink slightly while baking. Make sure to build the edges higher for the best results.
Planning a full brunch spread? Pair this quiche with a batch of Cheesy Pesto Tomato Puffs or my Baby Potatoes with Whipped Feta for the ultimate comfort-table moment that always impresses.
With its unique sweet potato base, this quiche boasts a distinct flavour complemented by a creamy spinach and Gruyere filling that takes it to a whole new level. Perfect for brunch or a light dinner, this dish is surprisingly easy to prepare.

Simple Ingredients, Big Flavours
This quiche proves that everyday ingredients can come together to make something seriously impressive — all you need are a few favourites you probably already have on hand.
Sweet Potatoes: The heart of this recipe. When pressed firmly into the tin, sweet potatoes bake into a sturdy, sliceable crust that actually holds like a real pastry — no crumbly disasters here. It’s the same base-hacking magic that makes my Crushed Potato Quiche with Chicken and Pesto such a hit, just with a sweeter twist.
Spinach: This leafy green brings that classic Florentine feel along with fibre, iron, and vibrant colour. A quick wilt in the pan and it’s ready to shine. If you love spinach-forward meals, try my Salmon and Spinach Tortilla Quiches next.
Shallot & Garlic: Small ingredients with big personality. Shallot brings delicate sweetness, while garlic adds that comforting savoury aroma that makes kitchens smell like home.
Eggs + Creamy Filling: Eggs are what help this quiche bake into clean, confident slices that hold their shape beautifully. Blending cream and milk gives the filling that luxurious, café-style smoothness without feeling too heavy — just pure brunch elegance. If you’re into creamy, perfectly set fillings, you’ll also love my Salmon and Asparagus Quiche, which use the same silky technique to create a soft, custardy centre.
Gruyere Cheese: Rich, nutty, melts like a dream — Gruyere is the flavour powerhouse that takes this quiche straight into brunch-hero territory.
Lemon Zest & Nutmeg: Two tiny additions that totally elevate the flavour. Lemon zest keeps everything fresh and bright, while nutmeg adds warmth and depth for the most balanced bite.
Simple Steps for Perfect Sweet Potato Quiche Florentine
Start by boiling the sweet potatoes until tender. Once cooked, crush them and press them firmly into a greased baking tin to form a sturdy base—don’t forget to build the edges higher.
Drizzle olive oil over the base and season with salt and pepper before baking. While the base roasts, melt butter in a frying pan and sauté sliced shallots and minced garlic until softened. Add fresh spinach and cook until wilted.
In a bowl, whisk together eggs, heavy cream, and milk, seasoning with salt and pepper. Stir in nutmeg and lemon zest, then fold in the Gruyere cheese.
Once the sweet potato base is ready, add the sautéed spinach, and pour the custard mixture over the top.
Return the quiche to the oven and bake until set. For the complete recipe with measurements, be sure to scroll down!

-
In a frying pan, melt butter, add shallot and garlic, cook until softened, then add spinach. Cook until wilted and set aside (if the mixture is too watery, drain the spinach).

Whisk eggs, cream, milk, salt, pepper, nutmeg, and lemon zest. Add Gruyere cheese and whisk well. Pour this mixture over the sweet potato base after adding the spinach.

Bake for 30-35 minutes at 180°C until settled. Enjoy!

Note
Sweet Potato Base: Press the sweet potatoes firmly into the tin to form a sturdy base. Since sweet potatoes have a higher water content than regular potatoes, the sides may shrink slightly during baking, so be sure to build them up high!
Spinach Tip: If your spinach releases too much water, drain or pat it dry before adding to the quiche to avoid a soggy filling.
Cheese Options: Gruyere adds a lovely nuttiness, but feel free to use your preferred cheese. Feta or cheddar would work well.
Leftovers: This quiche can be stored in the fridge for up to 3 days. Enjoy it cold or reheat in the oven at 160°C until warmed through. Avoid microwaving to preserve texture.
Serving Ideas: Delicious on its own or served with a fresh salad for a light, balanced meal.
Freezing: I wouldn’t recommend freezing this quiche, as the texture will be lost upon thawing.
