Preheat oven to 190°C. Bring a large pot of salted water to a rolling boil. Cook jumbo pasta shells until just shy of al dente, about 10 minutes. Drain immediately and transfer to a large rimmed baking sheet. Drizzle lightly with olive oil and gently toss to prevent sticking.

In a large skillet over medium heat, warm 2 tablespoons oil from the sun-dried tomato jar. Once shimmering, add finely chopped shallots and minced garlic. Cook, stirring occasionally, for 3 to 5 minutes until softened and fragrant.

In a large mixing bowl, combine prepared spinach, ricotta cheese, remaining 30 ml grated Parmesan, lemon zest, and 0.25 teaspoon each kosher salt and black pepper. Mix thoroughly until uniform.

Spoon ricotta-spinach filling evenly into each pasta shell. Place filled shells aside until ready to bake.

To the skillet with aromatics, add slivered sun-dried tomatoes, 210 ml Parmesan, Italian seasoning, remaining salt and black pepper. Stir to combine. Add chicken or vegetable broth and half-and-half or cream. Simmer for 5–7 minutes, stirring frequently, until sauce slightly thickens.

Pour half of the sun-dried tomato sauce into a 3-litre (9×13 cm) baking dish. Arrange stuffed shells in a single layer over the sauce. Spoon remaining sauce evenly over the shells and scatter with shredded mozzarella.
