Preheat oven to 400 degrees Fahrenheit. Add olive oil to a 9x13 inch baking dish and toss with the tomatoes and garlic cloves, with about 1/2 teaspoon kosher salt. Make a well in the center of the tomatoes and add the Boursin cheese. Bake for 10 minutes.
Remove the tomatoes from the oven and toss them around. Add in the orzo, broth, Italian seasoning, and torn spinach leaves. Stir it all together. Bake for 20-25 minutes at 400F or until all the liquid has absorbed in the orzo.
Stir again to incorporate all the elements. Taste and add more salt and pepper if needed. Top with fresh basil leaves and serve warm!
Notes
For leftovers, the orzo will absorb more of the liquid and can become dry. Before reheating, stir in a splash of broth or heavy cream (for a creamy texture).
To add protein, stir in grilled chicken or shrimp at the very end before topping with basil.
This recipe makes roughly 6-8 side dish portions and 4 large main dish portions.
