What Kind of Feta Cheese Should I Use?

When it comes to feta, I prefer using a block of feta cheese stored in brine. It has a creamier texture and a bolder flavor compared to pre-crumbled versions. The block also holds up better while baking, creating little pockets of melted, salty goodness throughout the quiche. However, if you’re in a pinch, crumbled feta works just fine too—just try to choose a high-quality brand for the best result.

Options for Substitutions

Even though this crustless quiche is delicious as is, it’s also flexible if you need to make some swaps:

• Spinach: Fresh spinach is my favorite here, but you can substitute it with frozen spinach (just make sure to thaw and squeeze out all the excess moisture).
• Feta cheese: Goat cheese, ricotta salata, or even sharp white cheddar can offer a different twist while keeping the flavor profile vibrant.
• Tomatoes: Cherry or grape tomatoes work best, but sliced Roma or heirloom tomatoes are lovely alternatives—just pat them dry to avoid excess moisture.
• Eggs & milk: If you want to make it dairy-free, unsweetened almond milk or oat milk can be used. And for a richer quiche, replace some of the milk with cream.
• Add-ins: Feel free to toss in sautéed mushrooms, diced bell peppers, or caramelized onions for added depth.

Ingredients for This Crustless Spinach, Tomato & Feta Quiche

Each ingredient in this quiche plays an important role in building its fresh, savory flavor and light, custard-like texture.

• Eggs: The foundation of the quiche. They bind everything together and create that creamy, soufflé-like texture.
• Milk: Helps lighten the egg mixture while keeping the quiche moist. Whole milk gives a richer result, but low-fat milk can be used too.
• Fresh spinach: Adds a pop of green, subtle earthiness, and great nutrition. It wilts perfectly into the egg mixture without overwhelming the dish.
• Cherry tomatoes: Juicy and slightly sweet, they burst with flavor and look beautiful dotting the top.
• Feta cheese: Brings a salty, creamy contrast to the eggs and veggies. It softens as it bakes and gives every bite a touch of tang.
• Salt and black pepper: Essential for seasoning the egg base—keep it simple so the veggies and cheese can shine.
• Olive oil: Just a little is used to sauté the spinach, adding richness and helping it blend seamlessly into the mix.

Step 1: Prepare the Oven and Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or quiche pan with olive oil or non-stick spray to prevent sticking and help the edges brown beautifully.

---

Step 2: Sauté the Spinach

Heat a small amount of olive oil in a skillet over medium heat. Add the fresh spinach and cook for 2–3 minutes until wilted. Remove from heat and let it cool slightly before adding to the egg mixture. This step helps reduce excess moisture in the quiche.

---

Step 3: Whisk the Eggs and Milk

In a large mixing bowl, whisk together the eggs and milk until smooth and slightly frothy. Season with a pinch of salt and freshly ground black pepper. This is the base that will create the light, custardy texture of the quiche.

---

Step 4: Assemble the Quiche

Add the sautéed spinach to the egg mixture and stir gently. Pour the mixture into the prepared dish. Then, evenly distribute the halved cherry tomatoes over the top, cut side up. Crumble the feta over everything, letting some pieces sink while others stay on top for a golden finish.

---

Step 5: Bake to Perfection

Transfer the dish to the oven and bake for 35–40 minutes, or until the center is just set and the top is slightly golden. A knife inserted in the center should come out clean. Let it cool for a few minutes before slicing.

---

How Long to Cook the Crustless Spinach, Tomato & Feta Quiche

The quiche should be baked in a preheated 375°F (190°C) oven for 35 to 40 minutes. The exact time can vary slightly depending on your oven and the depth of your dish, so keep an eye on it during the final minutes. The center should be set but still tender, and the top should have a slight golden color. If the edges start to brown too quickly, you can loosely cover them with foil.

Tips for Perfect Crustless Quiche

• Drain your spinach well: Whether you use fresh or frozen spinach, it’s important to remove as much moisture as possible to avoid a watery quiche.
• Use room temperature eggs: This helps the eggs whisk more smoothly and bake evenly.
• Don’t overbake: The quiche will continue to cook slightly after being removed from the oven. Pull it out once the center is just barely set to avoid a dry texture.
• Add feta last: Sprinkle the feta on top after pouring in the egg mixture to ensure some of it stays visible and gets slightly golden.
• Let it rest: Allow the quiche to cool for 10–15 minutes before slicing. This helps the structure set and makes serving cleaner and easier.

Watch Out for These Mistakes While Cooking

Even with a simple recipe like this one, a few common missteps can make a difference:

• Adding wet ingredients without draining: Extra water from spinach or juicy tomatoes can lead to a soggy center. Always sauté and drain well.
• Using too much cheese: While tempting, excess cheese can make the quiche overly salty or greasy. Stick to the amount listed.
• Skipping preheating: The quiche won’t cook evenly if your oven isn’t at the right temperature from the start.
• Overmixing the eggs: You want a gentle whisk to incorporate air, not an overly frothy base that might puff and deflate too much.
• Not greasing the pan: Even without a crust, sticking can happen—especially around the edges.
