Bring a large pot of salted water to a boil. Add the gnocchi and cook according to package instructions until they float to the surface. Drain and set aside.

In a skillet, heat olive oil over medium heat. Add the heavy cream and bring to a simmer.

Stir in the chopped spinach, smoked salmon, dill, lemon zest, salt, and pepper. Cook for 3-5 minutes until the spinach is wilted and the sauce is heated through.

Add the cooked gnocchi to the skillet and gently toss to coat in the sauce. Serve immediately, garnished with additional dill if desired.
