Instructions

This easy casserole can be made in both an Instant Pot and a slow cooker. Here’s how to prepare it using each method.

Instant Pot Instructions

Pour 1 cup of beef broth into your Instant Pot. Add the frozen meatballs to the bottom of the pot. Next, layer the frozen ravioli on top of the meatballs.

Pour the entire jar of spaghetti sauce over the ravioli. Close the lid and make sure the valve is set to sealing.

Set the manual or pressure cook button to 1 minute. When the time is up, let the pot sit for 5-10 minutes. This is called a natural pressure release (NPR).

After the NPR, move the valve to venting. Open the lid and stir the contents. Your casserole is ready to serve!

For extra flavor, top with some grated parmesan or mozzarella cheese.

Slow Cooker Instructions

Making this casserole in a slow cooker is even simpler. Start by putting all the ingredients into your slow cooker. This includes the broth, meatballs, ravioli, and spaghetti sauce.

Give everything a gentle stir to mix it up a bit. Put the lid on your slow cooker.

Set your slow cooker to low and cook for 4 hours. If you’re in a hurry, you can cook it on high for 2 hours instead.

Once the cooking time is up, stir the casserole. It’s now ready to serve! Just like with the Instant Pot version, you can add some cheese on top if you like.

Possible Substitutes List & Recipe Variations

You can easily swap out ingredients in this Instant Pot casserole to match your tastes. Try using chicken or turkey meatballs instead of beef for a lighter option.

Don’t have ravioli? No problem! Substitute tortellini or your favorite pasta shape. Just make sure to adjust the cooking time if using regular pasta.

For the sauce, feel free to use marinara, Alfredo, or even a creamy tomato soup. Each will give your dish a unique flavor profile.

Here are some tasty variations to try:

• Mexican-style: Use taco-seasoned ground beef, cheese tortellini, and enchilada sauce
• Veggie-packed: Add a bag of frozen mixed vegetables to boost nutrition
• Cheesy delight: Stir in 1-2 cups of shredded cheese after cooking

Want to make it vegetarian? Use veggie meatballs or crumbled plant-based protein. You can also skip the meatballs and add extra veggies or beans for protein.

Remember, the beauty of this recipe is its flexibility. Don’t be afraid to get creative with your ingredient combinations!

Tips, Tricks & Storing

Use frozen ingredients for this casserole. It’s quick and easy with no thawing needed.

Try different ravioli flavors like cheese, spinach, or mushroom to mix things up.

Add some veggies like frozen peas or spinach for extra nutrition. Toss them in with the other ingredients.

For a spicier kick, use arrabbiata sauce instead of regular spaghetti sauce.

Make a big batch and freeze leftovers in single portions. Perfect for busy weeknights!

To reheat, microwave for 2-3 minutes or warm in the oven at 350°F for 15-20 minutes.

Store leftovers in an airtight container in the fridge for up to 3 days.

For a cheesier dish, mix in some shredded mozzarella before serving.

Want a vegetarian version? Swap the meatballs for veggie balls or extra ravioli.

Serve with a side salad and garlic bread for a complete meal.
