How to Make Slow Cooker Sausage and Peppers Recipe
Step 1: Brown the Sausage
Start by browning the Italian sausage in a skillet over medium heat. This step is key because it seals in all those juices and develops a golden crust that adds incredible flavor to the final dish. Don’t rush this part—let the sausage get a nice color before moving it to the slow cooker.
Step 2: Transfer Sausage to Slow Cooker
Once browned, transfer the sausage to your slow cooker. This is where the magic begins, as the sausage will slowly release its flavorful oils and infuse the other ingredients with depth and richness.
Step 3: Add the Veggies
Next, toss in the sliced bell peppers, onion, and minced garlic. These fresh ingredients bring bright, vibrant flavors and a satisfying texture to the dish. The garlic, in particular, will mellow and sweeten during the slow cooking.
Step 4: Pour in Tomatoes and Season
Pour the diced tomatoes over the sausage and veggies, then sprinkle in the Italian seasoning, salt, and pepper. Stir everything gently to combine all the flavors and ensure even cooking.
Step 5: Slow Cook to Perfection
Cover your slow cooker and set it to cook on low for 6 hours or on high for 3 hours. The long, slow simmer is what makes this Slow Cooker Sausage and Peppers Recipe truly exceptional, melding aromas and tenderizing every ingredient beautifully.
Step 6: Garnish and Serve
Once done, garnish with fresh basil leaves for a burst of color and herbal intensity that will brighten every bite, then get ready to dig in!
