Essential Ingredients for Mexican Dump Casserole

One of the best things about this casserole is that the ingredients are flexible, affordable, and often already in your kitchen. Here’s a breakdown of the most common components:

Protein:

• Ground beef: The classic base, browned and seasoned with taco spices.

Canned Goods:

• Corn: Adds natural sweetness and texture.

• Black beans: For protein, fiber, and a creamy bite.

• Rotel or diced tomatoes with green chilies: Adds zest and acidity. Rotel brings a little extra heat!

• Sour cream: Optional or used alongside the soup for a tangier flavor.

Flavor Builders:

• Taco seasoning: Store-bought or homemade, essential for that Tex-Mex flavor punch.

• Crushed tortilla chips or Doritos: These add crunch and saltiness to every layer.

• Shredded cheddar cheese: Use sharp cheddar for flavor, or a blend for meltiness.

Optional Spicy Add-ins:

• Sliced jalapeños

• Hot sauce or chili flakes

• Green chilies

Tip: Use low-sodium canned vegetables and beans if you want more control over the saltiness of the final dish.

Customization Options

Want to tweak the recipe? Go for it! This casserole is endlessly flexible and can be tailored to your tastes or dietary needs. Here are some easy ways to make it your own:

Protein Swaps:
