In a skillet over medium heat, brown the sliced Italian sausage until nicely browned. This adds depth of flavor. Once browned, transfer it to the crockpot.
Add the diced bell peppers, chopped onion, and minced garlic into the crockpot with the sausage. Stir to combine all the ingredients.
Layer the diced potatoes on top of the sausage and vegetable mix in the crockpot.
Pour in the diced tomatoes (with their juices), followed by the frozen corn. Sprinkle the oregano, paprika, salt, and black pepper over the top.
Gently stir everything together, ensuring that the spices and liquids mix well throughout.
Cover the crockpot and cook on low for about 6-8 hours or on high for 3-4 hours, until the potatoes are fork-tender.
About 30 minutes before serving, add the shredded cheddar cheese on top, re-cover, and allow it to melt.
Once done, stir well before serving to mix the melted cheese throughout the dish.
Notes
Serve in bowls garnished with fresh parsley. Pair with crusty bread or a green salad.
