Before you start

Before starting, ensure all your ingredients are prepped and ready. Slice the Italian sausage into uniform coins and cut the polenta tube into even, half-inch thick rounds. Have your Italian seasoning packet opened and the crushed tomatoes ready to pour.

It is helpful to clear your workspace and ensure your slow cooker is placed on a heat-safe surface with easy access to a power outlet. Having everything organized beforehand makes the assembly process smooth and efficient, allowing you to get the slow cooker started in just a few minutes.

Ingredients at a glance (6)
  • 1 lb Italian sausage, sliced into coins
  • 1 tube pre-cooked polenta, sliced into rounds
  • 1 packet Italian seasoning
  • 24 oz crushed tomatoes
  • 1 cup shredded fontina cheese
  • Fresh parsley, for serving

Instructions

Assembly Phase

  1. Layering the slow cooker
    Place the sliced Italian sausage coins into the bottom of the slow cooker, followed by the sliced polenta rounds layered evenly on top.
    Look for Sausage is evenly distributed at the bottom.
    Tip Ensure the polenta rounds are sliced to a uniform thickness for even cooking.

During this phase, ensure the sausage coins are arranged in a single layer at the bottom of the slow cooker to ensure direct contact with the heat. The polenta rounds should be placed carefully on top, creating a stable foundation for the tomatoes.

Check that the seasoning is distributed evenly over the polenta to ensure every bite is flavorful. Once the tomatoes are poured, the slow cooker is ready for the long simmer, and you should ensure the lid is securely in place to retain heat and moisture.

Cooking Phase

  1. Seasoning and simmering
    Sprinkle the Italian seasoning packet over the polenta, then pour the crushed tomatoes over the top. Cover and cook on high for 4 hours, ensuring the internal temperature of the sausage reaches 160°F (71°C).
    Look for Tomatoes are bubbling and sausage is cooked through.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Do not stir the mixture before cooking to maintain the layered structure.

As the dish simmers, you will notice the aroma of Italian herbs and savory sausage filling the kitchen. The crushed tomatoes will gradually thicken and meld with the sausage fat to create a rustic sauce. You can occasionally peek through the lid, but try to keep it closed as much as possible to maintain a consistent temperature. By the end of this phase, the polenta will have absorbed the flavors of the sauce and the sausage will be fully cooked, tender, and juicy.

Finishing Phase

  1. Adding cheese and serving
    Top the cooked dish with shredded fontina cheese and fresh parsley. Serve warm while the cheese is melted.
    Look for Cheese is melted and bubbly.
    Tip The residual heat from the slow cooker will melt the cheese perfectly.

This final phase is all about the garnish and presentation. Once you sprinkle the fontina cheese over the hot dish, it will begin to melt almost instantly from the residual heat. The fresh parsley adds a vibrant pop of color and a touch of freshness that cuts through the richness of the sausage and cheese. Check that the cheese is fully melted and bubbly before serving. This is the moment to adjust any final seasoning if desired, though the slow cooking usually balances everything perfectly.

Common mistakes

Avoid the temptation to stir the ingredients after layering them in the slow cooker, as this will break apart the polenta rounds and ruin the presentation. Another common mistake is using too little liquid; the crushed tomatoes provide the necessary moisture, so ensure you use the full amount specified to prevent the dish from drying out.

Lastly, be careful not to crowd the slow cooker beyond its capacity, as this can lead to uneven cooking and may result in the sausage not reaching the safe internal temperature.

How to tell it’s done

The dish is considered done when the Italian sausage has reached an internal temperature of at least 160°F (71°C), as measured by a meat thermometer. At this point, the tomatoes should have reduced slightly into a rich sauce, and the polenta rounds will be heated through and tender to the touch.

The fontina cheese should be completely melted, creating a golden, gooey layer on top of the dish. If the sausage has not yet reached the required temperature, continue to cook for an additional 15 to 20 minutes.

  • Ground meat: 160°F (71°C) in the thickest part
