Creamy Mexican White Trash Casserole Dessert Recipe

Mexican White Trash Casserole – The Ultimate Comfort Food Dinner

This Mexican White Trash Casserole comes together in just 30 minutes, making it the perfect weeknight dinner when you need something hearty, cheesy, and deeply satisfying. The creamy mixture of seasoned beef, tender rice, black beans, corn, and melty cheese creates layers of flavor and texture that feel like a warm hug on a plate.

I first made this casserole on a chilly evening after a long day exploring the farmers market in my small coastal town, and it instantly became a family favorite. It is one of those recipes that feels indulgent but uses simple pantry staples you likely already have.

Ingredients

• 1 pound ground beef
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 packet taco seasoning
• 1 can (15 ounces) black beans, drained and rinsed
• 1 can (15 ounces) corn, drained

• 2 cups cooked white rice
• 2 cups shredded Mexican blend cheese
• 1 cup sour cream
• Salt and pepper to taste
• Optional toppings: chopped cilantro, diced avocado, sliced jalapeños, extra sour cream, hot sauce

Instructions

• Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish.
• In a large skillet over medium-high heat, cook the ground beef with diced onion until the beef is browned and the onion is soft, about 6 to 8 minutes. Drain any excess fat.
• Add minced garlic and taco seasoning to the skillet and cook for 1 minute until fragrant.
• Stir in the black beans, corn, Rotel tomatoes, cooked rice, and sour cream until everything is well combined. Season with salt and pepper to taste.
• Transfer the mixture to the prepared baking dish and spread it into an even layer.
• Sprinkle the shredded Mexican blend cheese evenly over the top.
• Bake for 15 to 20 minutes, until the cheese is melted and bubbly around the edges.
• Remove from the oven and let it rest for 5 minutes before serving. Add your favorite toppings and enjoy.

Pro Tips

• Use day-old rice if possible, as slightly dried rice absorbs the flavors better and keeps the casserole from turning mushy.
• Let the casserole rest after baking so the layers set and it holds its shape when you scoop it.
• For extra texture, add a layer of crushed tortilla chips on top before the cheese for a subtle crunch.
• If you want a spicier kick, use hot Rotel or add a diced jalapeño when cooking the beef.
• Watch the cheese closely during the last few minutes of baking; once it is fully melted and golden in spots, it is ready.

Variations

• Swap the ground beef for ground turkey or chicken for a leaner option without losing flavor.
• Use brown rice or cauliflower rice for a lower-carb version that still feels hearty.
• Add a layer of refried beans spread on the bottom of the dish before adding the beef mixture for extra creaminess.
• Top with sliced olives, green onions, or a drizzle of ranch dressing for a fun twist.

Frequently Asked Questions

• Can I make this casserole ahead of time? Yes, assemble the casserole completely but do not bake it. Cover and refrigerate for up to 24 hours. When ready, bake as directed, adding 5 to 10 minutes if needed.
• How do I store leftovers? Store in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through.
• Can I freeze this casserole? Absolutely. Bake it first, let it cool completely, then wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
• What can I use instead of Rotel tomatoes? Use a can of diced tomatoes plus a small can of diced green chilies, or add a teaspoon of chili powder and cumin to regular diced tomatoes.
• Is this recipe gluten-free? Yes, as long as you use a gluten-free taco seasoning and ensure your Rotel tomatoes are gluten-free. Most brands are, but always check the label.
• Can I add more vegetables? Yes, diced bell peppers, zucchini, or spinach work well. Sauté them with the onion and beef to remove excess moisture before adding to the casserole.
