Before you start

Before beginning, ensure that your slow cooker is clean and positioned on a stable, heat-resistant surface. Slice the red onions into uniform, thin half-moons to ensure they soften evenly during the cooking process. Have all your ingredients measured out and ready to go.

If you are serving this with polenta, prepare it separately according to the package instructions just before the sausages finish cooking, so both components are ready to be served hot at the same time.

Check that you have a meat thermometer available to confirm the sausages reach the safe internal temperature of 160°F (71°C).

Ingredients at a glance (5)
  • 8 links smoked sausages
  • 2 large red onions, sliced
  • 1 tbsp all-purpose flour
  • 1/4 tsp ground nutmeg
  • 1 1/2 cups dry red wine

Instructions

Layering the ingredients

  1. Prepare the slow cooker base
    Place the smoked sausages in the bottom of the slow cooker vessel. Ensure they are arranged in a relatively even layer to allow for consistent heat distribution throughout the cooking process.
    Look for The sausages should be placed in the bottom of the cooker.
    Tip Do not crowd the sausages too much to allow the sauce to circulate.
  2. Add aromatics and seasonings
    Layer the sliced red onions over the sausages. Sprinkle the all-purpose flour and ground nutmeg evenly over the top of the onions to help thicken the sauce during the cooking cycle.
    Look for The flour should be dusted evenly over the onions.
    Tip Use a light hand when sprinkling the flour to avoid clumps.

At the end of this phase, the slow cooker should be filled with the sausages, onions, and seasonings. The setup should look organized, with the onions covering the meat to provide a protective layer that steams the sausages gently. Ensure the flour is distributed evenly to avoid clumping when the liquid is added.

Slow braising process

  1. Pour the wine and slow cook
    Pour the red wine over the entire mixture. Cover the slow cooker with its lid and set to cook on low for 4 hours. This allows the wine to reduce and the flavors to meld into the sausages.
    Look for The liquid should cover the base of the sausages.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Ensure the lid is tightly sealed to maintain moisture.

During this phase, the kitchen will be filled with the deep, savory aroma of red wine and simmering onions. The liquid should be bubbling gently, and the onions should be slowly turning into a rich, dark sauce. The sausages will become infused with the wine and spices, creating a tender, flavorful final product.

Final service preparation

  1. Serve the dish
    Once the cooking time is complete, verify that the sausages have reached an internal temperature of 160°F (71°C). Let the dish rest for 5 minutes before serving hot over creamy polenta.
    Look for The sauce should be slightly thickened and the onions softened.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Serve immediately while steaming hot.

By the end of this phase, the sausages should be fully cooked, tender, and coated in a thick, glossy sauce. The onions should be soft and integrated into the liquid. Check the internal temperature of the sausages to ensure they have reached 160°F (71°C) before serving them immediately over a bed of warm, creamy polenta.

Common mistakes

A common mistake is using a wine that is too sweet, which can overpower the savory notes of the smoked meat and onions. Stick to dry varieties to maintain the balance. Another error is overloading the slow cooker, which prevents the heat from circulating properly and can lead to uneven cooking of the sausages.

Ensure there is enough space around the sausages for the wine and onions to surround them. Finally, do not skip the resting period; allowing the meat to sit for a few minutes helps the juices redistribute, resulting in a more succulent texture.

How to tell it’s done

The dish is considered done when the sausages are tender and have reached an internal temperature of at least 160°F (71°C). Visually, the sausages should appear plump and slightly darkened from the red wine. The onion slices should be completely translucent and softened, having incorporated into a thick, glossy sauce.

If the sauce appears too thin, you can remove the lid for the final 20 minutes of cooking to allow for a slight reduction, though the flour should typically provide sufficient body to the final braising liquid.

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