SAUSAGE: In oven-safe skillet over medium-high heat, add oil. Sauté onion until golden (5 minutes). Add minced garlic and cook for another 30 seconds. Push onion and garlic to the skillet edges, then add sausage. Break apart and cook until browned (7-10 minutes). Turn off heat.
DRAIN GREASE: IF needed, drain excess grease from the skillet (Note 5). Return sausage to the pan.
BAKE: Add marinara sauce, 1/2 tsp pepper, Italian seasoning, water, and ravioli to the skillet. Stir gently and press ravioli into an even layer below liquid as much as possible. Bake for 10 minutes.
FINISH: Remove skillet from oven. Stir and spread ingredients. Press in even layer. Drop spoonfuls of Boursin cheese evenly over the dish. Sprinkle mozzarella and Parmesan cheese on top. Bake for 5 more minutes until cheese melts. Top with fresh herbs if desired. Serve immediately.

Notes
Note 1: If you don't have an oven-safe skillet, prepare meat sauce in skillet then transfer everything to a 9x13-inch casserole dish. Note 2: Choose between sweet or spicy Italian sausage based on preference. Remove casings if using sausage links.Note 3: Use fresh, not frozen, ravioli for this recipe. Rana's® Mozzarella Cheese Ravioli is recommended.Note 4: For Parmesan cheese, grate a block using the small holes of a cheese grater.Note 5: To drain grease from sausage, line a small bowl with foil and place a strainer on top. Pour contents of the skillet into the strainer and discard grease once cooled.Storage: Best served the same day. Leftovers can become mushy due to ravioli absorbing liquid. Not suitable for freezing and thawing.
