Crustless Spinach, Ham & Cheddar Quiche

Description

Crustless Spinach, Ham & Cheddar Quiche is an easy, savory, protein-rich breakfast or brunch dish made with fluffy eggs, creamy cheddar cheese, tender spinach, and flavorful diced ham. Because it skips the traditional pastry crust, this quiche is lighter, quicker to prepare, and naturally lower in carbohydrates while still being wonderfully satisfying.

The combination of salty ham, melted cheddar, earthy spinach, and seasoned eggs creates a comforting flavor in every bite. The edges become lightly golden while the center stays soft, tender, and creamy.

This recipe is perfect for breakfast, brunch, lunch, meal prep, family dinners, holidays, potlucks, and busy weekday mornings. It can be served warm with a simple green salad, roasted vegetables, fresh fruit, or toasted bread.

One of the best things about a crustless quiche is how customizable it is. You can easily add mushrooms, bell peppers, onions, tomatoes, herbs, or substitute turkey, cooked chicken, or another favorite cheese.

Ingredients

Main Ingredients

• 8 large eggs
• 1 cup milk
• ½ cup heavy cream or half-and-half
• 1½ cups shredded sharp cheddar cheese
• 1½ cups cooked ham, diced
• 3 cups fresh baby spinach
• ½ small yellow onion, finely diced
• 2 cloves garlic, minced
• 1 tablespoon olive oil or butter
• ½ teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon garlic powder
• ½ teaspoon dried thyme
• ¼ teaspoon paprika
• ¼ teaspoon nutmeg, optional

Optional Ingredients

• ½ cup sliced mushrooms
• ½ cup diced bell pepper
• 2 tablespoons fresh parsley
• 2 tablespoons chopped green onions
• ¼ teaspoon red pepper flakes
• ¼ cup grated Parmesan cheese
• ½ cup halved cherry tomatoes

Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9-inch deep-dish pie plate or quiche dish with butter or nonstick cooking spray.

Greasing the dish well is important because the egg mixture can stick as it bakes.

Set the prepared dish aside.

Step 2: Cook the Onion

Heat olive oil or butter in a large skillet over medium heat.

Add the finely diced onion.

Cook for approximately 3–4 minutes, stirring occasionally, until softened and translucent.

The onion should become fragrant without becoming heavily browned.

Step 3: Add Garlic

Add the minced garlic.

Cook for approximately 30–60 seconds.

Stir constantly and avoid burning the garlic.

The goal is simply to release its aroma.

Step 4: Add the Spinach

Add the fresh spinach to the skillet.

At first, it may look like too much spinach, but it will quickly shrink as it cooks.

Cook for approximately 2–3 minutes, stirring frequently, until wilted.

Remove the skillet from the heat.

Step 5: Remove Excess Moisture

This is an important step for a successful crustless quiche.

Spinach contains a lot of water, and excess moisture can make the quiche watery.

Allow the cooked spinach mixture to cool slightly.

If it looks very wet, transfer it to a fine-mesh strainer or clean kitchen towel and gently press out excess liquid.

Don’t skip this step if you’re using frozen spinach.

Step 6: Prepare the Egg Mixture

Crack the eggs into a large mixing bowl.

Add milk and heavy cream or half-and-half.

Whisk until the eggs are completely combined.

Add:

• Salt
• Black pepper
• Garlic powder
• Thyme
• Paprika
• Nutmeg, if using

Whisk again.

Don’t overbeat the eggs excessively. You want them well combined but not filled with too much air.

Step 7: Add the Cheese

Add approximately 1¼ cups of shredded cheddar to the egg mixture.

Reserve the remaining cheese for the top.

Stir gently.

Sharp cheddar provides a strong flavor, meaning you don’t need to use an excessive amount.

Step 8: Add the Ham and Vegetables

Add the diced ham.

Then add the cooled spinach and onion mixture.

Stir gently until everything is evenly distributed.

If using mushrooms, peppers, green onions, or other optional ingredients, add them now.

Step 9: Pour Into the Baking Dish

Pour the egg mixture into the prepared pie dish.

Spread the ham, spinach, and cheese evenly throughout the dish.

Sprinkle the remaining cheddar over the top.

For an extra cheesy finish, you can add a small amount of Parmesan.

Step 10: Bake

Place the dish in the preheated oven.

Bake for approximately 35–40 minutes.

The edges should be lightly golden, and the center should be set but still have a very slight jiggle.

Avoid overbaking.

Eggs continue cooking from residual heat after they leave the oven.

Step 11: Rest Before Slicing

Remove the quiche from the oven.

Let it rest for 10–15 minutes before slicing.

This allows the eggs to finish setting and makes the slices easier to cut.

Garnish with fresh parsley or green onions.

Serve warm.

Tips for the Best Crustless Quiche

Tip 1: Use Room-Temperature Eggs

Room-temperature eggs mix more evenly with the dairy.

Tip 2: Don’t Overfill the Dish

Leave a little space at the top because the eggs will puff slightly during baking.

Tip 3: Drain Vegetables

Any vegetables containing a lot of water should be cooked first.

Tip 4: Shred Your Own Cheese

Freshly shredded cheese often melts more smoothly.

Tip 5: Check Early

Ovens vary, so begin checking around the 32-minute mark.

The center should be set but not completely firm while still hot.
