STEP-BY-STEP INSTRUCTIONS:
Here’s where most people mess up their slow cooker cowboy casserole—overcooking or bland seasoning—but not you!
- Brown your ground beef over medium-high heat until no pink remains. Don’t stress the splatter; that’s where flavor starts. Drain excess fat if desired for a leaner casserole.
- Add chopped onions to the beef pan and sauté quickly to soften and bring out sweetness. This builds an irresistible slow cooker beef casserole flavor base.
- In your slow cooker, combine browned beef and onions with black beans, corn, diced tomatoes with green chilies, and taco seasoning. Stir well to make sure every bite is bursting with flavor.
- Set your slow cooker to LOW and cook for 4-5 hours or HIGH for 2-3 hours. Pro tip for slow cooker cowboy casserole perfection: stirring halfway through unlocks even flavor coating throughout.
- 30 minutes before serving, sprinkle shredded cheddar cheese evenly on top and cover. Let it melt and meld into the slow cooked cowboy casserole wonderfully cheesy goodness.
- Right before serving, top with crushed tortilla chips for that phenomenal crunch contrast you want in every bite.
- Taste and adjust salt, pepper, or add jalapeños for heat. Your slow cooker cowboy casserole should look vibrant, smell smoky and inviting, and feel like a warm hug on a plate.
