Heat 3 tablespoons olive oil in a 10-inch skillet over medium-high heat.
Add 10 ounces refrigerated gnocchi and fry, stirring occasionally, until golden and crisp, about 3–5 minutes; transfer gnocchi to a bowl or plate and set aside.
Reduce heat to medium-high and add 1½ cups heavy whipping cream, ¾ cup chicken broth, 1 teaspoon garlic powder, 1 tablespoon Italian seasoning, and 1 cup grated Parmesan to the skillet; whisk continuously until the sauce begins to thicken, about 6–8 minutes.
Stir in 1 cup chopped baby spinach and ½ cup drained sun-dried tomatoes and simmer until the spinach wilts, about 1–2 minutes.
Return the fried gnocchi to the skillet and gently toss to coat with the sauce and heat through, about 1–2 minutes.
Serve immediately.
Notes
Use refrigerated gnocchi for quickest results.
Whisk the sauce constantly to prevent scorching.
Drain oil from sun-dried tomatoes if packed in oil.
