Step-by-Step Instructions for Slow Cooker Sausage and Peppers
Step 1: Prepare the Vegetables
Wash the bell peppers under cold running water, then remove the stems and slice each pepper in half. Carefully scoop out the seeds and white membranes, and cut the bell peppers into long, even strips. Peel the yellow onions, slicing them into thin strips, and mince the garlic cloves finely, preparing for the flavorful assembly.
Step 2: Brown the Sausages
Pat the Italian sausage links dry with paper towels to facilitate browning. In a large skillet, heat the olive oil over medium-high heat. Once hot, place the sausage links into the skillet and brown them for 2 to 3 minutes on each side until they are lightly golden. Transfer the browned sausages to a clean plate, allowing them to rest while you build the dish.
Step 3: Layer the Ingredients
In a 6-quart slow cooker, place half of the sliced bell peppers at the bottom, followed by half of the sliced onions. Sprinkle the minced garlic over this vegetable layer. Next, arrange the browned Italian sausage links in a single layer over the vegetables to ensure they cook evenly and infuse their flavors into the dish.
Step 4: Add More Vegetables
Top the sausages with the remaining sliced bell peppers and then spread the rest of the sliced onions over them. This layering will create a beautifully vibrant structure, helping to develop flavors as the slow cooker works its magic.
Step 5: Prepare the Tomato Sauce
In a medium mixing bowl, pour in the crushed tomatoes and add the diced tomatoes with their juices. Mix in the tomato paste, low sodium chicken broth, Worcestershire sauce, and all the dried herbs and seasonings including oregano, basil, Italian seasoning, garlic powder, onion powder, smoked paprika, salt, and black pepper. Stir till thoroughly combined for a rich, aromatic sauce.
Step 6: Combine and Cook
Pour the seasoned tomato sauce evenly over the sausages and vegetables in the slow cooker. Gently press the vegetables down into the sauce to ensure they are well coated. Cover the slow cooker securely with its lid, set it to LOW, and let it cook for 5 to 6 hours, ensuring the sausages become tender and flavorful.
Step 7: Check for Doneness
Avoid lifting the lid frequently as you cook! After 5 hours, check the sausages' internal temperature with a meat thermometer; they should reach at least 160°F (71°C). If they haven’t reached the desired temperature, continue cooking until they do for safe and delicious results.
Step 8: Finish and Serve
Once cooked, remove the lid carefully, allowing steam to escape. Gently stir the peppers and onions around the sausages, tasting the tomato sauce to adjust salt and pepper if needed. If a thicker consistency is desired, let the sauce rest uncovered for 5 minutes. Finally, sprinkle freshly chopped parsley and basil over the finished dish before serving warm with hearty hoagie rolls, pasta, or mashed potatoes.
