If you like light, lemony pastas as much as I do, this easy casserole — and I mean so easy it all come together in one baking dish — is going to be your jam. Ravioli straight from the freezer goes into a trusty baking dish with a sauce of white wine, broth, garlic, and thyme. It magically thickens up during baking with the help of cornstarch. Topped with thinly sliced lemons, it all bakes together into a luscious casserole that requires zero stove time and can be assembled in the time it takes the oven to heat up. Scatter some peas from the freezer on top and you now have a pasta casserole that took very little effort, but yields some amazing results.
