How To Make Slow Cooker Ravioli

  1. Spray the slow cooker generously with cooking spray.
  2. Pour 15 ounces of crushed or diced tomatoes into the bottom of the slow cooker. Place the frozen ravioli over the tomatoes in an even layer. Sprinkle the Italian seasoning, salt, pepper, garlic powder, onion powder, and the grated Parmesan over the ravioli. Add 3 cups of shredded mozzarella on top of the ravioli and then pour the remaining 24 ounces of crushed or diced tomatoes over the cheese.
  3. Cook on HIGH for 2–3 hours or on LOW for 4–6 hours, until the ravioli are heated through and the sauce is bubbling. Sprinkle the remaining 1 cup of mozzarella over the top just before serving so it melts into a golden layer.

FAQs & Tips

What kind of ravioli should you use?

This recipe works with frozen ravioli. Beef, chicken, or cheese-filled ravioli all work well—choose your favorite or what’s convenient.

Can you use a store-bought sauce?

Yes. If you prefer, substitute the crushed or diced tomatoes with a jarred pasta or marinara sauce for a quicker option and bolder flavor.

Can I add vegetables to this recipe?

Absolutely. Add chopped bell peppers, zucchini, onions, mushrooms, or fresh spinach. Sturdier vegetables like peppers and zucchini are best added at the start; delicate greens can be stirred in toward the end.

How do you store leftovers?

Keep leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave until warmed through.

What size slow cooker should you use?

A 6-quart slow cooker is ideal for this recipe. It gives enough room for layering and even cooking.
