2 cups marinara sauce
1/3 cup mascarpone cheese
1/4 cup chopped fresh flat-leaf parsley
2 teaspoons chopped fresh thyme
1 pound purchased cheese tortellini
2 ounces thinly sliced smoked mozzarella (I used regular, couldn't find smoked)
1/4 cup freshly grated Parmesan cheese
Preheat the oven to 350 degrees. Lightly oil an 8 X 8 X 2-inch baking dish or 4 individual gratin dishes.
Whisk the marinara sauce, mascarpone cheese, parley, and thyme in a large bowl to blend. Cook the tortellini in a large pot of boiling salted water until just tender, about 2 minutes. Drain. Add the tortellini to the sauce and toss to coat.
Transfer the tortellini mixture to the prepared baking dish or dishes. Top with the smoked mozzarella cheese and Parmesan cheese. Cover the dish or dishes with foil and bake for 20 minutes, then remove the foil and bake uncovered until the sauce bubbles and the cheeses on the top melt, about 10 minutes longer.
