  • Whole milk: Adds creaminess and richness to the filling. You can substitute with half-and-half for an even richer taste!
  • Fresh spinach: Roughly chopped, it brings a pop of color and a nutritious boost to the dish. Feel free to use frozen spinach if that’s what you have on hand.
  • Crumble feta cheese: This tangy cheese adds a delightful creaminess and a burst of flavor that pairs perfectly with the caramelized onions.
  • Freshly ground black pepper: A dash of pepper adds a subtle kick, enhancing the overall flavor without overpowering it.
  • Ground nutmeg: Just a hint of nutmeg adds warmth and complexity to the quiche. It’s a secret ingredient that makes a big difference!

How to Make Caramelised Onion, Feta & Spinach Quiche

Now that we have our ingredients ready, let’s get down to the fun part—making this Caramelised Onion, Feta & Spinach Quiche! Follow these simple steps, and you’ll have a delicious dish that’s sure to impress.

Step 1: Preheat the Oven

First things first, preheat your oven to 375°F. This ensures it’s nice and hot when it’s time to bake your quiche. A well-preheated oven is like a warm hug for your dish, helping it cook evenly and perfectly!

Step 2: Prepare the Pie Crust

If you’re using a store-bought crust, place it into a 9-inch tart pan. Don’t forget to pierce the bottom with a fork—this helps prevent those pesky bubbles from forming while it bakes. Pop it in the oven for about 10 minutes, just enough to give it a head start. Once it’s done, let it cool while you work on the filling.

Step 3: Caramelise the Onions

In a large frying pan, warm up the extra virgin olive oil over medium heat. Add the sliced onions, brown sugar, and sea salt. Sauté those beauties for about 20-25 minutes. You want them to become soft and caramelized, turning a lovely golden brown. The smell will be heavenly, trust me! Just keep stirring occasionally to avoid any burning.

Step 4: Mix the Egg Filling

While the onions are caramelizing, grab a large bowl and beat the eggs and whole milk together until smooth. This is where the magic happens! Next, mix in the roughly chopped spinach and crumbled feta cheese. The spinach adds a vibrant color, while the feta brings that tangy goodness we all love.

Step 5: Combine Ingredients

Once your onions are beautifully caramelized and cooled slightly, gently fold them into the egg mixture. Be careful not to overmix; we want those lovely onion pieces to stay intact. This combination is what makes the Caramelised Onion, Feta & Spinach Quiche so special!

Step 6: Fill the Crust

Now it’s time to transfer that delicious filling into your cooled pie crust. Spread it out evenly, and if you’re feeling fancy, sprinkle some grated Parmesan cheese on top. This will give your quiche a lovely golden crust and an extra layer of flavor.

Step 7: Bake the Quiche

Slide your quiche into the oven and bake for 30-35 minutes. You’ll know it’s ready when the filling is firm and the top is a beautiful golden brown. Keep an eye on it, as ovens can vary. You want it to look as good as it tastes!

Step 8: Serve

Once it’s out of the oven, allow the tart to rest for about 10 minutes before slicing it into wedges. This little wait helps the filling set up nicely. You can enjoy it warm or at room temperature—perfect for brunch or a light dinner. Trust me, your family will be raving about this quiche!

Tips for Success

  • Always preheat your oven; it makes a world of difference in baking.
  • Let the caramelized onions cool slightly before adding them to the egg mixture to avoid cooking the eggs.
  • Feel free to experiment with different cheeses like goat cheese or cheddar for a unique twist.
  • For a gluten-free option, use a gluten-free pie crust or make a crustless quiche.
  • Make it ahead of time! This quiche stores well in the fridge for up to three days.

Equipment Needed

  • 9-inch tart pan: A must-have for shaping your quiche. If you don’t have one, a regular pie dish works just fine!
  • Large frying pan: For caramelizing those onions. A non-stick skillet is a great alternative.
  • Mixing bowl: Any large bowl will do for combining your ingredients.
  • Whisk: Perfect for beating the eggs and milk together. A fork can work in a pinch!

Variations of Caramelised Onion, Feta & Spinach Quiche

  • Swap the Cheese: Try using goat cheese or ricotta for a creamier texture and a different flavor profile. Each cheese brings its own unique twist!
  • Add Protein: For a heartier meal, consider adding cooked bacon, ham, or even shredded chicken. It’s a great way to use up leftovers!
  • Vegetable Medley: Mix in other veggies like bell peppers, mushrooms, or zucchini for added nutrition and color. Just sauté them briefly before adding to the filling.
  • Herb Infusion: Fresh herbs like dill, basil, or thyme can elevate the flavor. Toss in a tablespoon or two for a fragrant touch.
  • Gluten-Free Option: Use a gluten-free pie crust or make a crustless quiche by greasing the pan well and pouring the filling directly in.
  • Spicy Kick: If you like a bit of heat, add some red pepper flakes or diced jalapeños to the filling for a spicy surprise!

Serving Suggestions for Caramelised Onion, Feta & Spinach Quiche

  • Fresh Salad: Pair your quiche with a light mixed greens salad drizzled with a lemon vinaigrette for a refreshing contrast.
  • Fruit Platter: Serve alongside a colorful fruit platter for a sweet touch that balances the savory flavors.
