Sweet Potato & Rosemary Frittata: A Taste of Sunshine

The scent of rosemary always transports me back to my grandmother’s garden. She grew the most fragrant herbs, and rosemary was her favorite – she’d sneak it into everything! One memory that always lingers is the aroma of the rosemary sprigs she tucked around the sweet potatoes roasting in the oven on a chilly afternoon, promising a delicious, warming meal. This frittata captures that very essence, offering a simple yet satisfying dish that’s perfect any time of day. It’s like a ray of sunshine baked into a savory pie.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 6-8
• Yield: 1 frittata
• Dietary Type: Gluten-Free

Ingredients

• 450g orange sweet potatoes, peeled and cut into 2cm pieces
• 1 capsicum (bell pepper), cut into 2cm pieces
• 2 garlic cloves, thinly sliced
• 3 eggs
• 4 egg whites
• ½ teaspoon fresh rosemary leaves, chopped
• ⅓ cup Parmesan cheese, grated
• 2 tablespoons Parmesan cheese, grated for topping
• Salt and pepper to taste
• Olive oil flavored cooking spray

Equipment Needed

• 18cm x 28cm baking tin
• Silicone paper or parchment paper
• Large saucepan
• Non-stick frying pan
• Whisk
• Large bowl
• Cooling rack

Instructions

1. Begin by preheating your oven to 180°C (350°F). This ensures even cooking and a beautiful golden finish.
2. Line an 18cm x 28cm baking tin with silicone paper or parchment paper. This will prevent sticking and make it easier to remove the frittata once it’s cooked. Ensure the paper extends slightly over the edges for easy lifting.
3. Fill a large saucepan with water and bring it to a boil over medium-high heat.
4. Add the sweet potato pieces to the boiling water and cook for 5 minutes. This par-cooking step softens the sweet potato, ensuring it cooks through evenly in the frittata.
5. Drain the sweet potato thoroughly and set aside. Removing excess water is crucial to prevent a soggy frittata.
6. Spray a non-stick frying pan with olive oil flavored cooking spray and heat over medium-high heat. The olive oil spray adds a subtle flavor and helps prevent the capsicum from sticking.
7. Add the capsicum pieces to the pan and cook for 3 minutes, stirring occasionally. You want the capsicum to soften slightly but still retain some of its crispness.
8. Add the sliced garlic to the capsicum and cook for an additional 1 minute, stirring constantly. Be careful not to burn the garlic, as it can become bitter. The garlic should be fragrant and lightly golden.
9. Remove the pan from the heat and set the capsicum and garlic mixture aside.
10. In a large bowl, whisk together the eggs, egg whites, ⅓ cup of Parmesan cheese, chopped rosemary, salt, and pepper. Whisk until the mixture is well combined and slightly frothy. This will give the frittata a light and airy texture. Season generously with salt and pepper to enhance the flavors.
11. Pour the egg mixture into the prepared baking tin.
12. Top the egg mixture evenly with the cooked sweet potato and capsicum mixture. Distribute the vegetables so that each slice of the frittata will have a good balance of flavors and textures.
13. Sprinkle the remaining 2 tablespoons of Parmesan cheese evenly over the top of the frittata. This will create a golden, cheesy crust.
14. Bake in the preheated oven for 20 minutes, or until the frittata is golden brown and cooked through. To test for doneness, insert a knife into the center of the frittata; it should come out clean.
15. Remove the frittata from the oven and let it cool in the tin on a wire rack. This will prevent the bottom from becoming soggy.
16. Once cooled, slice the frittata and refrigerate in an airtight container until ready to serve. This frittata is delicious both warm and cold, making it perfect for a picnic or a light meal.

Expert Tips & Tricks

• For an extra layer of flavor, consider roasting the sweet potatoes instead of boiling them. Toss them with olive oil, rosemary, salt, and pepper and roast at 200°C (400°F) for 20-25 minutes, or until tender.
• If you don’t have fresh rosemary, you can use dried rosemary, but use half the amount as the flavor is more concentrated.
• To prevent the frittata from sticking, make sure the baking tin is well-lined with silicone paper. You can also lightly grease the paper with olive oil or cooking spray.
• If the top of the frittata is browning too quickly, you can loosely cover it with foil during the last few minutes of baking.
• Don’t overcook the frittata, as it will become dry and rubbery. It’s ready when the center is set and the edges are golden brown.
