Instructions
Arrange a shelf on the top third of the oven and pre-heat to 375 degrees.
Heat the oil in a large skillet over medium-low heat. Add in the mushrooms and onions and sauté until the vegetables have softened, about 8 to 10 minutes. Stir in the garlic and dried Italian herb seasoning and sauté until fragrant, about 1 minute. Stir in the marinara sauce, a ½ cup of water (if using jarred sauce...I like to pour the water into the jar and swish it around to get the rest of the sauce in the jar and then pour it in), salt and pepper, and simmer for 5 minutes to let the flavors meld. Taste and add more seasoning, if needed.
In a 9×13 or 3 quart baking dish, add in a cup of sauce as the first layer. Next, add a layer of ravioli (half of your ravioli), like pictured above. Add the layer of spinach, a half cup of sauce, and then 1 cup mozzarella cheese.
Next, add the remaining ravioli, sauce, and mozzarella cheese. Top with the freshly grated parmesan cheese. Be sure to cover all ravioli with the sauce and cheese.
Cover the baking dish with aluminum foil and transfer to the oven. Bake for 20 minutes, remove from the oven, and remove the foil. Return the dish to the oven uncovered. Bake until cheese is melted, bubbly, and golden, about 20 more minutes. (If you'd like the top to be slightly more browned on top, then place it under the broiler for a minute or two.)
Serve in bowls or plates and shower with fresh basil and parmesan cheese, if desired. Enjoy!
