Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 400°F (200°C).
Step 2: Cook the Butternut Squash
Heat a 10-inch oven-safe skillet over medium heat and add 2 tablespoons of butter. Once the butter has melted, add the cubed butternut squash, seasoned with a generous pinch of kosher salt and freshly ground black pepper. Cook for about 5 to 6 minutes, allowing the squash to soften. Add the remaining tablespoon of butter, then stir in the diced red onion and minced garlic. Continue to cook for an additional 5 minutes while stirring frequently, until the squash is tender. If the squash is not yet fork-tender, continue cooking for a few more minutes. Remove the skillet from heat.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, whisk together the large eggs, heavy cream (or half-and-half), chopped fresh sage, and parsley, along with the freshly grated Parmesan cheese. Season the mixture with a pinch of salt and pepper, and whisk until well combined.
Step 4: Combine and Bake
Pour the egg mixture into the skillet over the cooked butternut squash. Transfer the skillet to the preheated oven. Bake for 10 to 15 minutes, or until the frittata is set in the center. If the eggs are not fully set after the initial baking time, continue baking for an additional 2 minutes and then check again.
Step 5: Prepare the Arugula Salad
While the frittata is baking, prepare the arugula. In a separate bowl, toss the arugula with olive oil and a pinch of salt and pepper to taste.
Step 6: Serve the Frittata
Once the frittata is fully baked, remove it from the oven. Top the frittata with the dressed arugula and finished with shaved Parmesan cheese. Slice into squares or wedges according to your preference. This dish can be enjoyed hot or cold, and any leftovers can be stored in the refrigerator.

Cook techniques
Sautéing
Sautéing is a technique where food is cooked quickly in a small amount of oil or fat over relatively high heat. In this recipe, the butternut squash, onion, and garlic are sautéed in butter to enhance their flavors and soften their textures before being combined with the egg mixture.
Whisking
Whisking involves beating or stirring a mixture vigorously to incorporate air and create a smooth consistency. Here, the eggs, heavy cream, herbs, and Parmesan cheese are whisked together to ensure an even blend and a fluffy texture in the frittata.
Baking
Baking is a cooking method that uses dry heat in an oven. The egg mixture is poured over the sautéed vegetables and baked until set, resulting in a firm yet tender frittata.
Tossing
Tossing is a technique used to mix ingredients lightly without crushing them. The arugula is tossed with olive oil and seasoning, keeping the leaves whole and vibrant for a refreshing topping.
Slicing
Slicing involves cutting food into pieces with a sharp knife. After the frittata is cooked and topped with arugula and Parmesan, it is sliced into wedges or squares for serving.
FAQ
Can I use frozen butternut squash instead of fresh?
Yes, you can use frozen butternut squash. Just make sure to thaw and drain excess moisture before using it in the recipe.
What can I substitute for heavy cream?
You can substitute heavy cream with half-and-half, milk, or plant-based alternatives like almond milk or coconut cream, although the texture may vary.
How can I tell when the frittata is fully cooked?
The frittata is fully cooked when it is set in the center and does not jiggle when carefully shaken. If unsure, you can insert a knife into the center; it should come out clean.
Is there a way to make the frittata dairy-free?
Yes, you can use non-dairy cheese alternatives and substitute heavy cream with a non-dairy milk. Ensure the cheeses used are dairy-free.
Can I add other vegetables to the frittata?
Absolutely! Feel free to experiment with other vegetables like spinach, bell peppers, or mushrooms, according to your preferences. Just be sure to sauté them before adding the egg mixture.
