1. Preheat the oven to 200°C (400°F).
Bring a large pot of salted water to a boil. Once the water is boiling, add the pasta and cook until very al dente (at least 2 minutes less than the package instructions). Once cooked, remove the pasta from the original pot and set aside, they should no longer be exposed to heat (to avoid overcooking).
2. Sauté the minced shallot and garlic clove in a sauté pan or large wok with a little olive oil for 2 minutes.
3. Wash the spinach, squeeze out excess water, and add it to the sauté pan. Pour in the white wine and mix well.
4. Meanwhile, heat your tomato sauce over low heat and adjust the seasoning.
5. Once the spinach has wilted, add the bouillon cube and cream, mix well, and add the mascarpone.
Blend everything together and adjust the seasoning.
6. Pour the tomato sauce into the baking dish, arrange the pasta with the opening facing you, stuff them with the spinach mixture, crumble the mozzarella on top, and bake for 10 minutes.
7. Halfway through cooking, switch to the "grill" function.
Remove from the oven and serve immediately!
