How to Make Slow Cooker Sausage Casserole
Step 1: Brown the Sausage
Set a skillet over medium heat, drizzle in the olive oil, and add your sliced sausage. Sauté for 3 to 4 minutes, just until the edges take on a lovely golden color. This quick step locks in flavor and gives the finished casserole a mouthwatering depth you simply can’t get from raw sausage.
Step 2: Layer the Vegetables
Transfer the browned sausage to your slow cooker, then pile in the diced onion, minced garlic, potatoes, carrots, and red bell pepper. This colorful medley will soften and meld together as they cook, creating a melt-in-your-mouth texture and gorgeous presentation.
Step 3: Add the Tomatoes, Broth, and Seasonings
Pour the diced tomatoes (with their juices) over the veggies, followed by the tomato paste and chicken broth. Sprinkle in the thyme, smoked paprika, oregano, and a good pinch of salt and pepper. Stir gently to combine everything, making sure the flavors are evenly distributed.
Step 4: Slow Cook to Perfection
Pop the lid on your slow cooker and set it to low for 6 to 7 hours, or high for 3 to 4 hours. The magic happens as the casserole simmers away—your kitchen will smell heavenly, and the sausage and vegetables will become impossibly tender, wrapped in a thick, savory sauce.
Step 5: Garnish and Serve
Give the casserole a final stir, taste and adjust the seasoning if needed, then finish with a sprinkle of fresh parsley. It’s now ready to be ladled into bowls, piping hot and brimming with flavor!
