Ingredients
- 1.5 pounds ground beef (use halal ground beef)
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) sweet corn, drained
- 1 can (14.5 oz) diced tomatoes, drained
- 1 cup beef broth
- 1 packet taco seasoning (or 2 tbsp homemade)
- 1 cup cornmeal
- 1 cup buttermilk (or milk with 1 tbsp lemon juice)
- 1 egg, beaten
- 4 tbsp melted butter
- 1 cup shredded cheddar cheese
- Salt and pepper to taste
- Optional: chopped cilantro and sliced jalapeños for garnish
Step-by-step Instructions
- Prep the slow cooker and ingredients: Brown the ground beef in a skillet over medium heat with the chopped onion and garlic until no longer pink. Drain any excess fat. This is a great time to set your oven to bake a warm dessert to finish the meal.
- Mix the filling: In a large bowl, combine the cooked beef and onions with black beans, corn, diced tomatoes, beef broth, and taco seasoning. Stir until well combined. Season to taste with salt and pepper.
- Layer in the slow cooker: Pour the savory mixture into your slow cooker and spread it evenly.
- Make the cornmeal topping: In a separate bowl, whisk together cornmeal, buttermilk, beaten egg, and melted butter until smooth. The batter should be pourable but slightly thick.
- Add the topping and cook: Gently pour the cornmeal mixture over the beef mixture so it forms an even layer. Sprinkle shredded cheddar cheese over the top if you like a melty finish. Cook on LOW for 2.5–3 hours or on HIGH for 1.5–2 hours, or until the cornmeal topping is set and cooked through.
- Finish and serve: Let the casserole rest with the slow cooker lid off for 10 minutes before scooping. Garnish with cilantro and jalapeños if desired.
Tips for Success
- Use a shallow slow cooker insert for more even cooking of the topping; a deeper insert may require extra time. If you’re wondering about slow cooker timing for other cuts, this guide about whether ribs can be overcooked in a slow cooker can ribs be overcooked in slow cooker is a helpful read.
- Avoid lifting the lid frequently; heat loss slows cooking and can make the topping soggy.
- If the top isn’t browning, transfer the slow cooker insert to a preheated oven at 400°F for 5–8 minutes to finish the golden crust.
- For a creamier filling, swap half the beef broth for a can of cream-style corn. If you’re checking liquid levels for other slow-cooked dishes, this article about whether ribs should be covered in liquid in a slow cooker should ribs be covered in liquid slow cooker offers good general guidance.
Possible Variations
- Gluten-free: Use a certified gluten-free cornmeal and confirm taco seasoning is gluten-free. The recipe adapts naturally to gluten-free needs without changing texture or flavor.
- Streusel topping: For a sweeter, crumbly finish that pairs beautifully with a spicier filling, mix 1/2 cup flour, 1/3 cup brown sugar, 4 tbsp cold butter, and 1/4 tsp cinnamon; sprinkle over the cornmeal batter before cooking.
- Chicken version: Swap ground beef for cooked shredded chicken and reduce cooking time slightly; this pairs especially well if you also enjoy this slow-cooker chicken breast method slow-cooker chicken breast.
- Vegetarian option: Replace meat with extra beans, diced butternut squash, and a cup of cooked quinoa for added protein and texture.
Storage Recommendations
- Refrigerate: Store leftovers in an airtight container for up to 3–4 days. Reheat gently in the oven at 350°F or in the microwave until warmed through.
- Freeze: Portion into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating tip: To revive the topping, sprinkle a little extra cheddar and bake uncovered at 375°F for 10–12 minutes until bubbly.

FAQs
