## Ingredients You’ll Need

* **Eggs:** 6 large eggs form the base of the frittata. Use fresh, high-quality eggs for the best flavor and texture.
* **Milk or Cream:** ¼ cup of milk or cream adds richness and moisture to the frittata. You can use whole milk, 2% milk, almond milk, or heavy cream, depending on your preference.
* **Fennel Bulb:** 1 medium fennel bulb, thinly sliced. Fennel provides a subtle anise flavor that complements the other vegetables. Make sure to remove the tough outer layers and core before slicing.
* **Zucchini:** 1 medium zucchini, diced. Zucchini adds a mild flavor and a pleasant texture to the frittata.
* **Spinach:** 5 ounces (about 140g) fresh spinach. Spinach contributes a boost of nutrients and a slightly earthy flavor. You can use baby spinach or regular spinach, but make sure to wash and chop it if using regular spinach.
* **Onion:** ½ medium onion, diced. Onion adds a savory flavor base to the frittata.
* **Garlic:** 2 cloves garlic, minced. Garlic enhances the overall flavor of the dish.
* **Olive Oil:** 2 tablespoons olive oil. Olive oil is used for sautéing the vegetables and adds a touch of flavor.
* **Parmesan Cheese:** ¼ cup grated Parmesan cheese. Parmesan cheese adds a salty and savory flavor. You can substitute with other hard cheeses like Pecorino Romano.
* **Salt and Pepper:** To taste. Salt and pepper are essential for seasoning the frittata.
* **Optional Ingredients:**
* **Red Pepper Flakes:** A pinch of red pepper flakes adds a touch of heat.
* **Fresh Herbs:** Chopped fresh herbs like parsley, basil, or thyme can add extra flavor.
* **Cheese Variations:** Consider adding other cheeses like feta, goat cheese, or mozzarella for a different flavor profile.

## Equipment You’ll Need

* **Large Skillet:** A 10-inch oven-safe skillet is ideal for making the frittata. Cast iron skillets work particularly well. If you don’t have an oven-safe skillet, you can transfer the frittata to a baking dish after cooking it on the stovetop.
* **Mixing Bowl:** A large mixing bowl is needed for whisking the eggs and other ingredients.
* **Whisk:** A whisk is used to thoroughly combine the eggs, milk, and seasonings.
* **Cutting Board:** A cutting board is essential for chopping the vegetables.
* **Knife:** A sharp knife is needed for slicing and dicing the vegetables.
* **Measuring Cups and Spoons:** Measuring cups and spoons are needed for accurately measuring the ingredients.

## Step-by-Step Instructions with Detailed Explanations

Here’s a detailed guide on how to make the Spinach, Fennel, and Zucchini Frittata:

**Step 1: Prepare the Vegetables**

1. Wash and dry the fennel bulb, zucchini, and spinach thoroughly.
2. Trim the fronds from the fennel bulb, reserving a few for garnish if desired. Remove the tough outer layers of the fennel bulb and core it. Thinly slice the fennel bulb.
3. Dice the zucchini into small, even pieces.
4. If using regular spinach (not baby spinach), roughly chop it.
5. Dice the onion and mince the garlic.

**Explanation:** Preparing the vegetables ahead of time ensures that they cook evenly and consistently in the frittata. Thinly slicing the fennel allows it to soften and release its flavor during cooking. Dicing the zucchini ensures that it cooks through without becoming mushy. Chopping the spinach makes it easier to incorporate into the egg mixture.

**Step 2: Sauté the Vegetables**

1. Heat 1 tablespoon of olive oil in the oven-safe skillet over medium heat.
2. Add the diced onion and cook until softened and translucent, about 5-7 minutes.
3. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
4. Add the sliced fennel bulb and cook until it begins to soften, about 5-7 minutes.
5. Add the diced zucchini and cook until it starts to become tender, about 5 minutes.
6. Add the spinach and cook until it wilts, about 2-3 minutes. Stir occasionally to ensure even cooking.
7. Season the vegetables with salt and pepper to taste. Add a pinch of red pepper flakes if desired.
8. Remove the skillet from the heat and set aside.

**Explanation:** Sautéing the vegetables before adding the egg mixture helps to soften them and develop their flavors. Cooking the onion and garlic first allows their flavors to infuse the oil and coat the other vegetables. Adding the spinach last ensures that it doesn’t overcook and become mushy. Seasoning the vegetables at this stage helps to layer the flavors and create a more balanced dish.

**Step 3: Prepare the Egg Mixture**

1. In a large mixing bowl, whisk together the eggs, milk or cream, and Parmesan cheese.
2. Season the egg mixture with salt and pepper to taste.

**Explanation:** Whisking the eggs with milk or cream creates a smooth and homogenous mixture that will result in a light and fluffy frittata. Adding Parmesan cheese at this stage infuses the egg mixture with a savory flavor. Seasoning the egg mixture is crucial for ensuring that the frittata is well-seasoned throughout.

**Step 4: Combine the Vegetables and Egg Mixture**

1. Pour the egg mixture over the sautéed vegetables in the skillet, making sure to distribute it evenly.
2. Gently stir the mixture to ensure that the vegetables are evenly dispersed throughout the egg mixture.

**Explanation:** Pouring the egg mixture over the vegetables creates the base for the frittata. Gently stirring the mixture ensures that the vegetables are evenly distributed throughout the egg mixture, which will result in a more uniform texture and flavor in the finished dish.

**Step 5: Cook the Frittata**

1. Place the skillet on the stovetop over medium-low heat.
2. Cook for about 5-7 minutes, or until the edges of the frittata begin to set and the bottom is lightly golden brown.
3. Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the frittata is set in the center and lightly golden brown on top.
4. Alternatively, if you don’t have an oven-safe skillet, you can transfer the frittata mixture to a greased baking dish and bake in the oven for 20-25 minutes, or until set.

**Explanation:** Cooking the frittata on the stovetop first helps to create a lightly browned and crispy bottom. Transferring it to the oven allows the top to cook evenly and prevents it from burning. The frittata is done when the center is set and no longer jiggly. Using a toothpick inserted into the center can help determine doneness; it should come out clean.

**Step 6: Let it Cool and Serve**

1. Remove the frittata from the oven and let it cool in the skillet for a few minutes.
2. Run a spatula around the edges of the frittata to loosen it from the skillet.
3. Carefully slide the frittata onto a cutting board.
4. Cut the frittata into wedges and serve warm or at room temperature.
5. Garnish with reserved fennel fronds or fresh herbs, if desired.

**Explanation:** Letting the frittata cool slightly before cutting it helps it to hold its shape and prevents it from crumbling. Running a spatula around the edges makes it easier to remove from the skillet. Cutting the frittata into wedges makes it easy to serve and share. Garnish adds a touch of elegance and freshness to the dish.

## Tips and Variations

* **Add Cheese:** Experiment with different cheeses like feta, goat cheese, mozzarella, or Gruyere for a different flavor profile.
* **Use Different Vegetables:** Feel free to substitute or add other vegetables like bell peppers, mushrooms, asparagus, or cherry tomatoes.
* **Add Protein:** Incorporate cooked sausage, bacon, ham, or smoked salmon for a heartier frittata.
* **Make it Spicy:** Add a pinch of red pepper flakes or a dash of hot sauce for a kick.
* **Use Different Herbs:** Experiment with different fresh herbs like basil, thyme, rosemary, or oregano to customize the flavor.
* **Make it Ahead:** Frittatas can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
* **Serve it Cold:** Frittatas are also delicious served cold, making them perfect for picnics or lunchboxes.
* **For a Dairy-Free Version:** Substitute the milk or cream with a plant-based milk alternative like almond milk or soy milk. Omit the Parmesan cheese or use a vegan Parmesan alternative.
* **Add Sun-Dried Tomatoes:** Chopped sun-dried tomatoes add a burst of intense flavor.
* **Use Different Greens:** Replace the spinach with kale, chard, or arugula for a different nutrient profile and flavor.

* Serve it with a dollop of Greek yogurt or sour cream and a sprinkle of fresh herbs.

## Storage Instructions

* **Refrigerate:** Store leftover frittata in an airtight container in the refrigerator for up to 3 days.
* **Reheat:** Reheat the frittata in the oven at 350°F (175°C) for 10-15 minutes, or until warmed through. You can also reheat it in the microwave for 1-2 minutes, or until heated through. Be careful not to overheat it, as it can become dry.
* **Freeze:** While not ideal, you can freeze frittata. Wrap individual slices tightly in plastic wrap and then place them in a freezer-safe bag or container. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
