Easy Crockpot Italian Sausage Cheese Ravioli Casserole Step-by-step instructions

Before you start

Before beginning, ensure your slow cooker is clean and placed on a stable, heat-resistant surface. If you are using raw Italian sausage, brown it in a skillet until fully cooked, then drain any excess fat thoroughly.

Gather all your ingredients so they are within arm's reach. Having the marinara sauce measured and the seasoning packet ready to open will make the assembly process move quickly and smoothly, allowing you to get the slow cooker started without any unnecessary delays.

Instructions

Layering the ingredients

1. 1Prepare the base
   Place the pre-cooked and crumbled Italian sausage into the bottom of the slow cooker insert to create an even layer of flavor.
   Look for The sausage should be evenly distributed across the bottom of the vessel.
   Tip Ensure the sausage is fully browned and drained of excess fat before adding it to the slow cooker.
2. 2Layer the pasta
   Add the frozen cheese ravioli directly on top of the cooked sausage layer, ensuring they are spread out for even cooking.
   Look for The ravioli should form a single layer or slightly overlapping layer.
   Tip Keep the ravioli frozen until the very last second to ensure they hold their shape during the cooking process.

At this stage, your slow cooker should be filled with the sausage and ravioli. Ensure the pasta is spread in an even layer to promote consistent cooking. The visual goal is a neat arrangement that will hold its shape until the sauce is added. Check that your slow cooker is plugged in and ready to be set to the low setting before you move on to adding the seasonings and sauce.

Seasoning and saucing

3. 3Season the dish
   Evenly sprinkle the contents of the Italian seasoning packet over the layer of frozen ravioli to infuse the pasta with savory herbs.
   Look for The herbs should be visible across the surface of the pasta.
   Tip Shake the packet gently to distribute the seasoning uniformly rather than dumping it in one spot.
4. 4Add the sauce
   Pour the marinara sauce over the seasoned ravioli, ensuring all pieces are well-coated and submerged in the liquid.
   Look for The sauce should cover the ravioli completely to prevent them from drying out.
   Tip Use a spatula to gently push down any ravioli that remain exposed above the sauce line.

Once you have added the seasoning and poured the marinara, the ingredients should be fully submerged or at least well-coated. The aroma of the dried herbs should begin to emerge. Verify that no dry spots of seasoning remain on top of the pasta. At this point, the dish is ready for the long, slow cook that will meld all the flavors together into a delicious, cohesive casserole.

Slow cooking to perfection

5. 5Slow cook the casserole
   Cover the slow cooker and cook on low for 4 hours. Ensure the internal temperature of the sausage reaches 160°F (71°C) to confirm proper heating.
   Look for The sauce will be bubbling and the ravioli tender when finished.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Avoid lifting the lid during the cooking time to maintain consistent internal heat levels.
6. 6Rest and serve
   Allow the casserole to rest for 5 minutes after cooking to let the sauce thicken slightly before serving.
   Look for The casserole should look glossy and the cheese filling should be soft and melted.
   Tip Use a wide spoon to serve, careful not to break the delicate ravioli pillows.

After four hours on low, the casserole will be transformed. The ravioli should be perfectly tender and the sauce should have thickened into a rich, bubbling mixture. The internal temperature of the sausage should reach 160°F (71°C).

The kitchen should smell like a classic Italian kitchen. Give the mixture a gentle stir if necessary, but be careful not to break the delicate ravioli as you prepare to plate.

Common mistakes

A common mistake is using fresh ravioli instead of frozen, which often leads to the pasta overcooking and breaking apart into the sauce. Another error is failing to drain the fat from the cooked sausage, which can result in an oily casserole.

Finally, avoid opening the lid too frequently, as each time you lift the cover, heat escapes, significantly increasing the total cooking time and potentially causing the dish to cook unevenly or dry out.

How to tell it’s done

The casserole is ready when the ravioli are tender to the touch and the marinara sauce is bubbling and hot throughout. The sausage, having been pre-cooked, should be heated through to an internal temperature of 160°F (71°C).

When you lift the lid, the dish should look glossy and the edges of the ravioli should be soft. If the sauce appears too thin, let it sit for a few extra minutes to thicken before portioning it onto plates.
