This Baked Ravioli Casserole is the ultimate crowd-pleaser! It combines all the flavors of the classic Italian dish with the ease of a casserole. This easy dish combines layers of tender ravioli, gooey melted cheese, and hearty marinara sauce in a dish that's as comforting as it is effortless.
Preheat the oven to 350 degrees F. Spread 1 cup marinara sauce in a 9x13-inch dish, set aside.
Heat a skillet over medium-high heat. Grease if needed and add the ground beef. Cook until no longer pink, crumbling the beef into fine crumbles with a meat masher as you go.
Reduce heat to low. Stir in the onions, salt, pepper, oregano and mustard. Cook until onions are tender and translucent. Stir in the minced garlic. Cook for another 30 seconds, then stir in the half and half and remaining marinara sauce. Remove from heat.
Layer half of the ravioli over the marinara in the casserole dish, then spread half of the meat sauce on top and sprinkle with 1/2 cup shredded cheese.
Repeat with the remaining ravioli, meat sauce and finish off with the rest of the shredded cheese.
Cover with foil and bake for 20 minutes. Then remove foil and switch the oven to high broil for 2-3 minutes, or until the cheese is starting to brown a little (keep a close eye on it!)
Serve hot with grated parmesan or shredded mozzarella + fresh ground black pepper and enjoy!
Notes
You can use frozen ravioli for this casserole this bake.If using frozen ravioli, just add some additional bake time so that the frozen ravioli can cook all the way through. Store leftover ravioli casserole in an airtight container in the fridge for 3-4 days. Reheat individual portions in the microwave or the entire dish in the oven at 350°F until warmed through.
