Step-by-Step Instructions for Slow Cooker Sausages with Caramelized Onions
Step 1: Prepare the Sausages
Remove the sausage links from their packaging and pat them dry with paper towels to ensure even browning. Heat a large skillet over medium-high heat, adding 1 tablespoon of olive oil. Once hot, arrange the sausages in a single layer and brown them for 2 to 3 minutes on one side until golden.
Step 2: Finish Browning the Sausages
Carefully turn the sausages using kitchen tongs and continue to brown for another 3 to 4 minutes until all sides are nicely golden and crisp. Once browned, transfer the sausages to a clean plate, allowing them to rest while you prepare the onions.
Step 3: Sauté the Onions
Reduce the skillet heat to medium-low, then add the remaining olive oil and the unsalted butter. After the butter melts completely, add the thinly sliced yellow onions. Stir to coat them and cook for 20 to 25 minutes, stirring frequently, until they soften and develop a deep golden brown color.
Step 4: Caramelize the Onions
If the onions start browning too quickly, reduce the heat further. Sprinkle the brown sugar over the softened onions, stirring gently until dissolved. Continue to cook for an additional 3 to 5 minutes until the onions reach a rich golden brown hue and emit a naturally sweet aroma.
Step 5: Add Garlic and Flour
Add the finely minced garlic to the onions, cooking for another 30 seconds until fragrant. Then, sprinkle the all-purpose flour evenly over the caramelized onions and stir continuously for about a minute to cook away the raw flour taste, creating a flavorful base.
Step 6: Create the Gravy
Slowly pour in the low sodium beef broth while stirring, scraping the bottom of the skillet to release any flavorful browned bits. Add the Worcestershire sauce, balsamic vinegar, and Dijon mustard. Then, add the dried thyme, dried rosemary, smoked paprika, garlic powder, onion powder, black pepper, and salt, stirring well.
Step 7: Simmer the Onion Gravy
Allow the onion mixture to simmer gently for 2 to 3 minutes until slightly thickened. This rich gravy will enhance the flavor of your Slow Cooker Sausages with Caramelized Onions, bringing everything together beautifully.
Step 8: Transfer to the Slow Cooker
Spoon half of the caramelized onion gravy into the bottom of a 6-quart slow cooker. Arrange the browned sausage links on top of the onion mixture, then spoon the remaining gravy and onions evenly over the sausages. Ensure the onions surround the sausages for maximum flavor infusion.
Step 9: Slow Cook the Dish
Place the lid securely on the slow cooker and set it to low heat. Cook for 4 to 5 hours until the sausages are fully cooked and tender. For a quicker option, select the high heat setting for 2 to 3 hours, avoiding opening the lid frequently.
Step 10: Check for Doneness
To ensure perfect doneness, insert a meat thermometer into the center of the thickest sausage link; look for an internal temperature of 160°F for pork or beef sausages (165°F for poultry).
Step 11: Stir the Gravy and Serve
When done, carefully remove the slow cooker lid to release hot steam. Gently stir the caramelized onions into the rich gravy, tasting to adjust salt or black pepper as needed. Allow the gravy to rest uncovered for about 5 minutes if a thicker consistency is desired.
Step 12: Garnish and Enjoy
Spoon some of the gravy over the sausage links, sprinkling fresh thyme leaves and chopped parsley on top for a burst of color. Switch the slow cooker to the warm setting until ready to serve. Delight in your Slow Cooker Sausages with Caramelized Onions, perfect over mashed potatoes or with crusty bread!
