Chicken Cordon Bleu Lasagna

These delightful spinach balls transform humble spinach into an irresistible appetizer that's as nutritious as it is delicious. Tender spinach combines with savory Parmesan, crispy bread crumbs, and aromatic seasonings to create perfectly bite-sized morsels that are golden and crispy outside, soft and flavorful inside. Versatile enough to serve hot from the oven or at room temperature, these crowd-pleasing spinach balls will become your go-to appetizer for any occasion.

I served these at a holiday gathering last year, and they disappeared faster than any other appetizer on the table! My brother-in-law, who normally avoids anything green, asked for the recipe before the night was over. Even my picky five-year-old nephew gobbled them up, completely unaware he was eating spinach.

Ingredients

• Fresh spinach: Provides a vibrant green color, tender texture, and mild flavor that forms the nutritious base of these appetizers. Fresh spinach gives the balls a bright, clean taste.
• Eggs: Act as the essential binding agent that holds everything together while adding protein. They ensure the spinach balls maintain their shape during cooking.
• Bread crumbs: Create structure and absorb excess moisture, resulting in the perfect texture. Panko bread crumbs provide superior crispness compared to regular bread crumbs.
• Parmesan cheese: Delivers rich umami flavor and saltiness that elevates the mild spinach. Freshly grated Parmesan offers the best flavor, but pre-grated works well too.
• Onion: Adds aromatic flavor and subtle texture that complements the spinach. Finely mincing ensures it incorporates evenly throughout the mixture.
• Butter: Contributes richness and helps achieve that perfect golden exterior during baking. Melted butter distributes evenly throughout the mixture.
• Garlic powder: Provides aromatic depth without the texture of fresh garlic, which could overpower the delicate spinach.
• Italian seasoning: Delivers a balanced blend of herbs that enhances the Mediterranean flavor profile without requiring multiple individual herbs.
• Nutmeg: Introduces a subtle warmth and complexity that pairs beautifully with spinach and cheese. A little goes a long way!
• Black pepper: Adds a gentle heat that balances the richness of the cheese and butter.

Instructions

Step 1:

Prepare your cooking equipment by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. If using an air fryer, no preheating is necessary at this stage. The parchment paper prevents sticking and makes cleanup effortless. Position your oven rack in the center position for the most even heat distribution during baking.

Step 2:

Cook the spinach properly by placing 1 pound of fresh spinach in a large pan with 2 tablespoons of water. Cover and cook over medium heat, stirring occasionally, until the spinach is completely wilted, about 3-4 minutes. The key is to not overcook the spinach, which would make it lose its bright color and nutritional value. Transfer the wilted spinach to a fine-mesh strainer and gently press with the back of a spoon to remove excess moisture—this is crucial to prevent soggy spinach balls. Once drained, finely chop the spinach on a cutting board. The spinach should be moist but not wet.

Step 3:

Create your spinach mixture by whisking 3 large eggs in a large bowl until well beaten. Add 2 cups of panko bread crumbs, 1 cup of grated Parmesan cheese, 1/4 cup of finely minced onion, 1/4 cup (4 tablespoons) of melted butter, 1/2 teaspoon of garlic powder, 1 teaspoon of Italian seasoning, 1/8 teaspoon of freshly ground nutmeg, and 1/4 teaspoon of black pepper. Mix these ingredients thoroughly until well combined. This creates a flavorful base with the perfect proportion of dry to wet ingredients. Then fold in the chopped spinach, making sure it's evenly distributed throughout the mixture. The resulting mixture should be moist enough to hold together when formed into balls but not overly wet.

Step 4:

Form consistent, attractive balls by using a 1.5 tablespoon cookie scoop (#40) to portion the mixture. This ensures uniformly sized balls that will cook evenly. Roll each portion between your palms to create a smooth, round shape. The warmth of your hands helps compress the mixture, resulting in balls that hold together well during cooking. Place the formed balls on the prepared baking sheet, leaving about 1 inch of space between each to allow hot air to circulate for even browning. Depending on the size of your baking sheet, you may need to work in batches.

Step 5:

Choose your cooking method based on your available time and equipment. For oven baking, place the baking sheet in the preheated oven and bake for approximately 30 minutes, or until the spinach balls are golden brown on the outside. For air frying, place a single layer of spinach balls in the air fryer basket, leaving space between each ball. Cook at 380°F for about 10 minutes, shaking the basket halfway through, until the balls are crispy and golden. The air fryer method is significantly faster and creates an exceptionally crispy exterior.

Step 6:

Test for doneness by inserting an instant-read thermometer into the center of a spinach ball. It should register 165°F (74°C), ensuring the eggs are fully cooked. Alternatively, cut one open to check that it's heated through and has a consistent texture throughout. The exterior should be golden and slightly crisp, while the interior remains tender and moist.

Step 7:

Serve with complementary dipping options for the best eating experience. These spinach balls are delicious on their own but truly shine when paired with a flavorful dip. Consider serving them with marinara sauce, tzatziki, whipped feta, or a simple garlic aioli. Arrange them on a serving platter with small bowls of various dips, allowing guests to choose their favorite pairings.

I discovered through experimentation that adding just a small pinch of freshly grated nutmeg makes a remarkable difference in the flavor profile. It's a classic pairing with spinach and cheese in European cuisine, and adds a subtle warmth and complexity that most people can't quite identify but absolutely love. My grandmother always added nutmeg to her creamed spinach, and this small addition carries on that tradition while elevating these spinach balls from good to extraordinary.

Perfect Spinach Selection and Preparation

The type and preparation of spinach significantly impacts the final result of your spinach balls. While this recipe calls for fresh spinach, frozen spinach works equally well with some adjustments. For fresh spinach, baby spinach offers a milder flavor and more tender texture, while mature spinach provides a more robust, earthy taste. Whichever you choose, the key lies in proper moisture removal. After wilting the spinach, allow it to cool slightly before pressing out the liquid—warm spinach releases moisture more readily than cold. For maximum liquid extraction, place the wilted spinach in a clean kitchen towel and twist tightly over the sink. When using frozen spinach (a 10-ounce package is equivalent to about 1 pound fresh), thaw it completely either overnight in the refrigerator or using the defrost function of your microwave. Then press it in a fine-mesh strainer or squeeze it in a kitchen towel until no more liquid comes out. The chopping step is less critical with frozen spinach as it's already broken down, but still beneficial for even distribution throughout the mixture. For spinach balls with distinct spinach pieces rather than a uniform green mixture, chop the spinach more coarsely and fold it in gently at the final stage.

Make-Ahead and Storage Strategies

These spinach balls are perfect for entertaining because they can be prepared in advance through several methods. For same-day preparation, form the balls up to 8 hours ahead and refrigerate them uncovered on a parchment-lined baking sheet. This not only saves time but actually improves the texture as the bread crumbs absorb flavors and moisture, resulting in more cohesive balls. For longer-term planning, freeze uncooked spinach balls on a baking sheet until solid (about 1-2 hours), then transfer to a freezer-safe container where they'll keep for up to 2 months. Cook them directly from frozen, adding about 5 minutes to the oven baking time or 2 minutes to the air fryer time. Already cooked spinach balls can be refrigerated in an airtight container for up to 3 days or frozen for up to 1 month. To reheat refrigerated balls, bake at 350°F for 10 minutes or air fry at 350°F for 3-4 minutes until warmed through. For frozen cooked balls, reheat at 350°F for 15 minutes or air fry at 350°F for 5-6 minutes. For the best texture when reheating, place the balls on a wire rack over a baking sheet rather than directly on the sheet—this allows air to circulate and helps restore their crispness.

Creative Variations for Every Occasion

While the classic spinach ball recipe is delicious, you can easily adapt it to suit different tastes or dietary needs. For a Mediterranean twist, add 1/4 cup of crumbled feta cheese, 2 tablespoons of chopped Kalamata olives, and 1 tablespoon of fresh dill. For an Italian variation, substitute the Parmesan with a combination of mozzarella and Pecorino Romano, add 2 tablespoons of sun-dried tomatoes, and increase the Italian seasoning to 1.5 teaspoons. To make them gluten-free, replace the panko with gluten-free bread crumbs or crushed Rice Chex cereal. For a dairy-free version, substitute the Parmesan with nutritional yeast and use olive oil instead of butter. To add more protein, incorporate 1/2 cup of finely chopped cooked chicken or crumbled cooked bacon. For a vegetable medley, replace half the spinach with finely chopped artichoke hearts or roasted red peppers. If serving as a main course rather than an appetizer, form larger balls (about 2.5 tablespoons each) and increase the cooking time by 5-7 minutes. These variations maintain the core characteristics of the original while offering exciting new flavor profiles for different occasions or preferences.
