This Slow Cooker Sausage Casserole is a comforting and hearty one-pot meal featuring savory sausage, tender vegetables, and a rich tomato-based sauce. Perfect for busy days, it uses a slow cooker to meld flavors deeply while you go about your day. With simple ingredients like potatoes, carrots, and frozen peas, it’s a delicious, easy-to-prepare dish that can be customized with your choice of sausage and topped with melted cheese for extra indulgence.

Ingredients

Scale

Sausage

  • 1 lb (450g) sausage (pork, chicken, or turkey – your choice)

Vegetables

  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 1/2 cups baby carrots, sliced
  • 1 1/2 cups potatoes, diced (Yukon Gold or Russet work well)
  • 1 cup frozen peas

Liquids and Canned Goods

  • 1 can (14.5 oz) diced tomatoes, undrained
  • 1 cup chicken broth

Spices and Seasonings

  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1/2 teaspoon paprika
  • Salt and pepper to taste

Optional Topping

  • 1 cup shredded cheese (cheddar or mozzarella – optional, for topping)

Instructions

  1. Prepare the Sausage: If using whole sausages, slice them into 1-inch pieces to allow even cooking and flavor distribution.
  2. Brown the Sausage: In a skillet over medium heat, cook the sausage pieces until browned, about 5-7 minutes, breaking them up into smaller pieces as they cook. If using pre-cooked sausage, slice and skip this step.
  3. Transfer to Slow Cooker: Place the browned sausage or uncooked sliced sausage into the slow cooker, setting the base for your casserole.
  4. Add Vegetables and Seasonings: Add chopped onion, minced garlic, sliced carrots, diced potatoes, the canned diced tomatoes with their juices, chicken broth, dried thyme, dried oregano, paprika, salt, and pepper into the slow cooker over the sausage.
  5. Cook the Casserole: Stir all ingredients gently to combine. Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the vegetables are tender and the sausage is thoroughly cooked through.
  6. Add Frozen Peas: About 30 minutes before serving, stir in frozen peas. Cover and continue to cook for the remaining time to heat the peas through without overcooking.
  7. Optional Cheese Topping: If desired, sprinkle shredded cheese evenly over the casserole 10-15 minutes before serving. Cover the slow cooker to allow the cheese to melt and become gooey.
  8. Serve: Before serving, stir the casserole to mix the melted cheese and ingredients evenly. Serve hot and enjoy your comforting meal.

Notes

  • You can use pork, chicken, or turkey sausage depending on your preference.
  • For a vegetarian version, substitute sausage with plant-based protein and use vegetable broth instead of chicken broth.
  • If you prefer a thicker sauce, remove the lid during the last 30 minutes of cooking to allow some liquid to evaporate.
  • This casserole can be prepared the night before; just refrigerate and cook in the slow cooker the next day.
  • Leftovers keep well in the fridge for up to 3 days and can be reheated on the stovetop or microwave.
