Bring a large pot of salted water to a rolling boil and add your pasta, cooking until just al dente, about 8-10 minutes. Drain and set aside, reserving a cup of pasta water.
While the pasta cooks, heat olive oil in a large skillet over medium heat until shimmering and fragrant.
Add the minced garlic and chili flakes to the skillet. Cook for about 1 minute, until the garlic becomes fragrant and slightly golden, filling your kitchen with a savory aroma.
Stir in the chopped sun-dried tomatoes and cook for another 2 minutes, allowing them to plump up slightly and release their smoky fragrance.
Add the chopped spinach to the skillet and cook for about 2 minutes, stirring until wilted and vibrant green, creating a fresh contrast in texture.
Transfer the drained pasta into the skillet, tossing to coat evenly with the flavorful sauce. Add a splash of reserved pasta water if the mixture looks dry, helping the sauce stick nicely to the noodles.
Sprinkle the grated Parmesan over the pasta, then add the lemon zest and squeeze in the lemon juice. Toss everything together until the cheese melts and the flavors meld, creating a glossy, flavorful coating.
Taste and adjust the seasoning with salt or chili flakes as needed. The pasta should be tender, coated in a fragrant, slightly spicy, and tangy sauce, ready to serve.
Serve the Lady Gaga pasta hot, garnished with extra Parmesan or lemon zest if desired. Enjoy the bold, spontaneous flavors with a side of your favorite bread or salad.
