A toaster oven is a (probably convection) oven and can be used in the same way as long as the food fits inside.

I have made foie gras in a toaster oven (very low heat in a water bath) and that was totally fine. I didn't have a terrine so just wrapped it into shape in saran wrap. I love toaster ovens so much.
