Preheat oven to 350F (175C) with rack in the centre of the oven. Oil or butter an 8-inch square baking dish, an 8-inch cast-iron skillet or individual baking dishes.
Bake in the preheated 350F (175C) oven uncovered for 20 to 25 minutes, until the sauce has bubbled up around the edges and the top has a nice golden crust. Let sit for a few minutes before serving.
