Ingredients and Substitutions

This recipe uses really simple, straightforward ingredients you probably have on hand.

• Frozen chopped spinach: You must thaw this completely and squeeze it very dry. Any extra water will make your quiche squares soggy. You could use fresh spinach but, you’d need to cook it down first.
• Crumbled feta cheese: This is where that classic Greek flavor comes from. I love the kind with oregano already in it, but plain feta works just fine.
• Shredded old cheddar cheese: This gives the squares a great sharpness and helps them melt together. You could swap this for Monterey Jack or even a mozzarella if you prefer a milder taste.
• Milk: Whole milk will give you a richer result, but 2% or even 1% works perfectly. I recommend blending it with milk, but use whatever ingredients you have on hand.
• Eggs: These are the binder that holds everything together.
• Flour: Just a little all-purpose flour helps give the squares structure.

You can add any additional ingredients you like to customize these quiche squares. These are great homemade Greek spinach and cheese quiche squares ideas. Try adding in cooked diced ham, tomatoes, bell peppers, olives or artichoke hearts.

Can I use cream instead of milk in quiche? Yes you can! I recommend blending it with milk, but use whatever ingredients you have on hand. To bake with cream instead of milk, replace the same amount of milk with cream to get a richer quiche.

Serving Suggestions

These quiche squares are great as a main dish, but also work nice served as an appetizer.

Serve them warm with some fresh greens or a crisp salad for the perfect meal! A simple salad with a vinaigrette is all you need for a simple Greek spinach and cheese quiche squares meal.

I also love these next to a simple cup of tomato soup. For brunch, a side of fresh fruit, or some crispy breakfast potatoes would be perfect. A dollop of Greek yogurt or tzatziki on top is a great finishing touch.

Tips for Success

• Squeeze the spinach dry. I mean it. Squeeze it in a colander, then wrap it in a clean kitchen towel or paper towels and squeeze again, extra water is the enemy of a firm quiche.
• For extra flavor and texture, try adding in chopped bacon pieces or mushrooms.
• Want a healthy Greek spinach and cheese quiche squares version? For a lighter version, substitute equal parts low fat milk and cream or just stick to using all milk!
• Don’t overbake. Pull the dish out when the center is just set. It will continue to cook as it stands.

How to Make It

Step 1: First, get your oven ready. Heat oven 350 degrees F (180 degrees C).

Step 2: Next, prepare your pan. Grab a 9-inch square baking dish. Bake butter in 9-inch square baking dish 2 minutes or until melted. You just want it soft and liquidy.

Step 3: Remove dish from oven; brush butter onto the bottom and sides of the dish. Make sure to get it all the way up the sides to prevent sticking.

Step 4: Now for the filling. Add and beat eggs with a mixer in a large bowl. Beat them until they are light and fluffy, about a minute.

Step 5: Add flour, milk, and baking powder, mix until blended. Just mix until the flour is combined. Don’t overdo it.

Step 6: It’s time for the main ingredients. Stir in spinach, cheeses, and onion. Fold them in gently with a spatula until everything is evenly mixed.

Step 7: Then spoon into the prepared dish. Spread the mixture evenly into your buttered baking dish. This is such a quick Greek spinach and cheese quiche squares recipe to pull together.

Step 8: Bake it for 35 minutes. You’ll know it’s done when the center is set and the edges are a lovely golden brown.

Step 9: This last step is important. Let it stand 15 minutes before cutting into squares. This lets the quiche set, so you’ll get to cleanly cut neat squares that don’t fall apart.

Enjoy!
