Ingredients

2 tablespoons neutral oil, such as Canola oil
1 white onion, diced
4 cloves garlic, finely minced
1 pound 80/20 ground beef
3 tablespoons taco seasoning (homemade or store-bought)
1 scallion, finely diced
1 (15-ounce) can pinto beans
1 (10-ounce) can RO*TEL Original Diced Tomatoes and Green Chilies
1 cup thick and chunky salsa
Salt and black pepper, to taste
1 1/2 cups cheddar cheese, plus more if needed
1 (9-ounce) bag Fritos Corn Chips

For serving (optional):

• Sour cream
• Pickled jalapenos
• Diced scallions
• Shredded lettuce

Steps

1. Sauté the aromatics: Set a large 12-inch skillet over medium heat and add the oil. Sauté the garlic and onion for 6-8 minutes until soft and translucent. You’ll know they’re ready when the onions turn golden and release their sweet aroma – this foundation builds incredible flavor depth for the entire casserole.
2. Cook the meat: Add the beef and break it into bite-sized pieces with a wooden spoon. Sauté for 6-8 minutes until nicely browned. The key here is getting good caramelization on the meat – don’t rush this step as those browned bits add serious flavor. If your taco seasoning doesn’t contain salt, add a generous pinch of salt to the meat while it cooks.
3. Preheat the oven: While the meat cooks, preheat the oven to 350°F (175°C). This timing ensures your oven is perfectly heated when you’re ready to bake.
4. Simmer the casserole: Reduce the heat to medium-low and stir in the taco seasoning, scallions, and pinto beans. Sauté for 1-2 minutes until well incorporated – you should smell the spices blooming. Add the RO*TEL and salsa, and simmer for 8-10 minutes, or until the flavors have melded nicely and the meat is well-seasoned. The mixture should look cohesive and smell incredibly aromatic. Taste and adjust with additional salt and pepper as needed.
5. Add the toppings: Immediately transfer the mixture to a 9×13-inch casserole dish and spread it in an even layer. Top with cheddar cheese and 2 cups of Fritos chips, plus more if desired. Don’t pack the chips down – just sprinkle them evenly to maintain their crunch.
6. Bake: Place in the preheated oven and bake for 10 minutes, or until the cheese is nicely melted and bubbling around the edges. The Fritos should still have some crunch while the cheese creates a golden, gooey layer.
7. Serve: Top the casserole with optional dollops of sour cream, pickled jalapeños, scallions, and shredded lettuce. Divide among serving plates and enjoy while hot for the best texture contrast.

Smart Swaps

• Greek yogurt instead of sour cream (1:1 ratio) – adds protein without changing texture
• Ground turkey instead of beef – reduces fat while maintaining flavor
• Black beans instead of pinto beans – adds more fiber and antioxidants

Make It Diabetes-Friendly

Replace the Fritos with 2 cups crushed pork rinds (reduces carbs by 28g per serving). Use 1 cup reduced-sugar salsa instead of regular (saves 4g carbs per serving). Serve 1/2 cup portions instead of full servings and pair with a large side salad to reduce glycemic impact. Total carb reduction: approximately 18g per serving (from 32g to 14g). The high protein and fat content helps slow glucose absorption.

Pro Tips

• Drain pinto beans but don’t rinse – the liquid adds extra flavor to the casserole
• Let the casserole rest for 5 minutes after baking so the cheese sets slightly for cleaner serving
