Prep Time15 minutes
Cook Time5 hours
Total Time5 hours 15 minutes
Course: Main Course
Cuisine: American
Servings: 6 servings

Ingredients

  • 14 ounces smoked sausage, cut into slices
  • 1 large white onion, finely chopped
  • 3 cloves garlic, minced
  • 6 medium russet potatoes (about 6 cups), peeled and cubed 
  • 1 green bell pepper, diced
  • 2 cups shredded cheddar cheese
  • 1 10.5 ounce can cream of chicken soup
  • 1 cup chicken broth
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • ½ teaspoon smoked paprika
  • Salt and pepper, to taste
  • 2 tbsps fresh parsley, chopped (for garnish)

Instructions

  • In a large skillet over medium heat, sear the sausage until browned on both sides. Remove the sausage from the skillet and set aside, leaving a small amount of fat in the skillet.
  • In the same skillet, add the chopped onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant. Remove from heat.
  • In the slow cooker, add the diced potatoes on the bottom. Add in the sausage, the cooked onions and garlic, the diced bell peppers, and half of the shredded cheddar cheese and stir together.
  • In a mixing bowl, whisk together the cream of chicken soup, chicken broth, dried thyme, dried oregano, smoked paprika, salt, and pepper. Pour this mixture evenly over the layered ingredients in the slow cooker.
  • Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the potatoes are tender. 15 minutes before serving, sprinkle the remixing cheddar cheese over the top and continue to cook until the cheese is melted. *Optional: If the sauce is too thin, mix 2 tablespoons of cornstarch with 2 tablespoons of water to create a slurry. Stir the slurry into the slow cooker and allow it to thicken for 5-10 minutes.
  • When ready, sprinkle the casserole with fresh chopped parsley and serve.

Notes

  • You can substitute russet potatoes with Yukon Gold or red potatoes for a different texture and flavor. You can even do a mix if you would like.
  • Feel free to mix and match cheeses according to your preference. Gruyere or pepper jack would add a nice twist.
  • Add spinach, mushrooms, or zucchini for extra nutrition and flavor.
  • You can prepare all the ingredients and refrigerate overnight. In the morning, add the liquid and start the slow cooker.
  • If the sauce is too watery, make a cornstarch slurry by adding 2 tablespoons of cornstarch and mix with 2 tablespoons of water until fully combined. Stir this into the potato casserole and allow the sauce to thicken for 5-10 minutes.
