How to Make Slow Cooker Cowboy Casserole

Follow these simple steps to prepare this delicious Slow Cooker Cowboy Casserole:

Step 1: Sauté the Beef
Heat olive oil in a large skillet over medium-high heat. Add the ground beef and kosher salt. Cook, breaking it up with a spoon, until it’s browned and cooked through, which should take about 6 minutes. Set aside.

Step 2: Add Aromatics
In the same skillet, toss in the chopped onions, finely chopped garlic, and taco seasoning. Stir them together and cook for another 3 minutes or until the onions soften and the garlic becomes fragrant.

Step 3: Mix it All Up
Transfer the beef mixture into a 6-quart slow cooker. Add in the chopped potatoes, rinsed kidney beans, drained corn, drained diced tomatoes, cream of chicken soup, and the can of diced green chiles. Press everything down into an even layer.

Step 4: Slow Cook to Perfection
Cover the slow cooker and set it to HIGH. Let it go for about 3 to 4 hours while the flavors meld together and the potatoes become tender. Stir occasionally if you can, but don’t worry if you can’t; it will still taste amazing!

Step 5: Melt the Cheese
After 3 to 4 hours, sprinkle the shredded Cheddar-Jack cheese evenly over the top of the casserole. Cover again and let it cook on HIGH for about 15 minutes, until the cheese melts and becomes gooey.

Step 6: Serve and Enjoy
Scoop the casserole into bowls and top each serving with a dollop of sour cream and a sprinkle of fresh cilantro leaves for that extra bright pop. This will make your taste buds dance with joy!
