Heat a 10-inch skillet over medium-high heat and add 3 tablespoons olive oil.
Add 10 ounces refrigerated gnocchi to the hot oil and fry, turning occasionally, until golden and crisp, about 3–5 minutes.
Transfer the fried gnocchi to a bowl or plate and set aside.
Reduce heat to medium and pour 1 1/2 cups heavy whipping cream and 3/4 cup chicken broth into the skillet; whisk to combine.
Add 1 teaspoon garlic powder, 1 tablespoon Italian seasoning, and 1 cup grated Parmesan cheese; whisk and cook over medium heat until the sauce begins to thicken, about 6–8 minutes.
Stir in 1 cup chopped baby spinach and 1/2 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.
Serve immediately while hot.
