Can I use frozen ravioli straight from the package?
Yes. Do not thaw frozen ravioli; add it directly to the skillet. It will cook through as the dish bakes in the oven.
What type of marinara sauce works best?
Use a good-quality jarred marinara (24 oz) or homemade sauce. Avoid overly chunky varieties if you prefer a smoother texture.
Can I make this ahead?
Yes. Assemble the skillet, cover with foil, and refrigerate up to 24 hours. Bake directly from cold, adding 5–10 minutes to cook time.
Can I substitute the Italian sausage?
Yes. Ground beef, ground turkey, or plant-based sausage work well. Brown and drain before adding to the skillet.
How do I know when it's done baking?
The ravioli should be tender, the sauce bubbling at the edges, and the mozzarella melted and lightly golden on top.
