Preheat the oven to 350°F (175°C).
Place the potato and zucchini medallions on a baking sheet lined with parchment paper and brush with 1 tbsp of olive oil. Roast in the preheated oven for about 15-20 minutes, or until slightly tender. Remove from the oven and let cool slightly.
1 medium potato, 2 medium zucchini
In a large bowl, whisk together the eggs, milk, Parmesan cheese, salt, black pepper, basil, and paprika.
8 egg, ¾ cup milk, ½ cup parmesan cheese, ¼ tsp salt, ¼ tsp pepper, ½ tsp basil, ½ tsp paprika
Heat the remaining 1 tbsp of olive oil in a large oven-safe skillet over medium heat. Add the green onion, garlic, and sundried tomato. Sauté until softened, about 5 minutes.
2 tbsp olive oil, 3 stalks green onion, 2 cloves garlic, ¼ cup sun-dried tomato
Add the roasted potato and zucchini medallions to the skillet, spreading them out evenly.
Pour the egg mixture over the vegetables in the skillet. Cook on the stovetop for a few minutes, or until the edges of the frittata start to set. Option to top with extra grated parmesan cheese.
Transfer the skillet to the preheated oven and bake for about 15-20 minutes, or until the frittata is set in the center and lightly golden on top.
Remove from the oven and let cool for a few minutes before slicing and serving.
