Step 1

Arrange a rack in the middle of the oven and heat the oven to 400ºF.

Step 2

Drain 1 (8.5-ounce) jar oil-packed marinated sun-dried tomatoes, then thinly slice the tomatoes. Place on a rimmed baking sheet. Add 1 pound fresh, shelf-stable, or frozen potato gnocchi. Drizzle with 2 tablespoons olive oil, season with 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper, and toss well to combine. Spread out in an even layer.

Step 3

Roast, stirring halfway through, until the gnocchi are plump, 18 to 20 minutes total. Remove from the oven, scatter 5 ounces baby spinach (about 5 packed cups) over the gnocchi, and toss gently. Return to the oven and roast until the spinach is just wilted, 2 to 3 minutes more. Garnish with grated Parmesan cheese, if desired.
