  • 1 cup shredded Colby Jack cheese
  • Crushed corn chips or crispy fried onions for garnish (optional)
  • Smoked paprika for garnish (optional)
  • Fresh cilantro for garnish (optional)
  • Sour cream for serving (optional)

Equipment

  • Slow Cooker (6-quart)
  • Large Pan

Method
 

Brown the Meat
  1. Heat olive oil in a large pan over high heat on your stovetop. Once the oil is shimmering and hot, add the ground Italian Sausage and the finely diced yellow onion.
  2. Brown and crumble the sausage, making sure to achieve some nice caramelization for maximum flavor. Season generously with salt and pepper while it cooks.
  3. Once the sausage is beautifully browned, transfer the browned sausage and onion mixture to your Crock-Pot.
Layer the Veggies
  1. Thinly slice the baby red potatoes, aiming for uniform pieces about 1/4 inch thick. Chop your green bell pepper, then drain and rinse the Kidney Beans thoroughly.
  2. Add the sliced potatoes, chopped bell pepper, drained beans, frozen corn, the undrained can of fire-roasted diced tomatoes, minced garlic, and chili powder to the Crock-Pot.
  3. Stir all these wonderful ingredients together to combine them well, then press them into an even layer in the Slow Cooker insert.
Slow Cook
  1. Cover your Crock-Pot with its lid and cook the casserole on high for 2–4 hours or on low for 4–6 hours. The goal is for the potatoes to be completely tender when pierced with a fork.
  2. Once the potatoes are tender, gently stir the casserole and taste. Adjust the seasoning with more salt and pepper if needed.
The Cheesy Finish
  1. Sprinkle the shredded Colby Jack Cheese evenly over the top of the hot casserole. Place the lid back on your Slow Cooker and let the cheese melt for about 5–10 minutes, or until it is perfectly gooey and bubbly.
  2. Right after the cheese melts, sprinkle on your crushed corn chips or crispy fried onions, perhaps with a dusting of smoked paprika. This ensures they stay wonderfully crunchy.
Serve
  1. Serve your Smoky Slow Cooker Cowboy Casserole hot and fresh. Offer optional toppings like a sprinkle of fresh cilantro and a dollop of cool sour cream for an extra burst of flavor and freshness.

Notes

For tender potatoes, slice baby red potatoes uniformly thin (1/4 inch). Avoid lifting the lid during cooking to maintain heat. Always drain and rinse kidney beans. Grate Colby Jack cheese fresh for a smooth melt. Store leftovers in an airtight container for 3-4 days in the fridge.
