Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
3 pounds ground beef
1 medium onion, diced
1 to 2 tablespoons olive oil
2 tablespoons butter
1/3 cup all-purpose flour
2 1/2 cups whole milk
2 cans (10 ounces each) Rotel diced tomatoes with green chilies, undrained
2 blocks cheddar cheese, freshly shredded
1/3 cup sour cream
2 to 3 tablespoons taco seasoning, divided
A few dashes hot sauce, to taste
10 to 12 nacho cheese hard taco shells
Optional Spanish rice for serving
Directions
Heat olive oil in a large heavy-bottomed pot over medium heat. Add diced onion and sauté for about 5 minutes until softened and translucent.
Add the ground beef to the pot. Sprinkle in half of the taco seasoning and cook until the beef is fully browned and crumbled, about 8 to 10 minutes.
Remove the cooked beef and onions from the pot, leaving some of the flavorful drippings behind.
Melt butter in the same pot over medium heat. Whisk in the flour continuously for 1 to 2 minutes until lightly golden and smooth.
Slowly pour in the milk while whisking to prevent lumps. Continue whisking until the mixture begins to thicken slightly.
Stir in the undrained Rotel tomatoes and green chilies.
Add the freshly shredded cheddar cheese gradually, stirring constantly until melted and creamy.
Mix in sour cream, hot sauce, and the remaining taco seasoning. Taste and adjust seasoning if needed.
Return the beef mixture to the pot and stir well to coat everything in the cheesy sauce. Simmer on low heat for 10 minutes until thick and flavorful.
Preheat the oven to 350°F (175°C). Arrange taco shells on a baking sheet and warm them for 5 minutes until crispy.
Fill each taco shell generously with the cheesy beef mixture and serve immediately.

Variations
Substitute ground turkey or chicken for a lighter option.
Use Monterey Jack or pepper jack cheese for a different flavor profile.
Add black beans or corn to stretch the filling and add texture.
Stir in diced jalapeños for extra heat.

Storage/Reheating
Store leftover taco filling in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze the cooled filling for up to 3 months.
To reheat, warm the filling gently on the stovetop over low heat or microwave in short intervals, stirring occasionally. Add a splash of milk if the sauce becomes too thick. Always fill taco shells just before serving to keep them crispy.
