Ingredients

3 pounds ground beef, use your preferred lean to fatty ratio for flavor and juiciness.
1–2 tablespoons olive oil, to sauté the onion and help prevent sticking.
1 medium onion, diced, adds sweetness and depth when softened.
Taco seasoning, to taste, provides classic taco flavor, adjust amount based on packet or homemade mix strength.
2 tablespoons butter, for the roux that makes the sauce rich.
1/3 cup all-purpose flour, thickens the sauce into a smooth consistency.
2 1/2 cups milk, creates a creamy base for the Rotel sauce.
2 cans (10 oz each) Rotel, undrained, adds tomato, green chile, and a bit of liquid for flavor and texture.

Step-by-step Instructions

Heat the skillet. In a large skillet, warm 1 to 2 tablespoons olive oil over medium heat. Add the diced onion and sauté until translucent, about 4 to 6 minutes. Tip: stir occasionally so the onion softens evenly.
Brown the beef. Add the 3 pounds ground beef to the skillet, breaking it up as it cooks. Sprinkle taco seasoning over the meat, stir to combine, and continue cooking until fully browned. Tip: cook until no pink remains and any excess liquid has reduced for better texture.
Make the roux. In a separate saucepan, melt 2 tablespoons butter over medium heat. Stir in 1/3 cup all-purpose flour and cook for 1 minute, stirring constantly to remove any raw flour taste.
Add milk and thicken. Gradually whisk in 2 1/2 cups milk, stirring continuously until the sauce thickens and coats the back of a spoon. Keep heat moderate so the milk does not scorch.
Combine with Rotel. Stir the undrained 2 cans (10 oz each) Rotel into the thickened sauce and heat through for 1 to 2 minutes. Taste and adjust seasoning if needed.
Assemble and serve. Spoon the seasoned beef mixture into taco shells and top with the cheesy Rotel sauce. Serve immediately while hot.

Tips, Storage, and Variations

Tips
- Use a splatter screen or keep the skillet partially covered when browning a large amount of beef to reduce splatter.
- If the sauce becomes too thick, whisk in a splash of milk until you reach the desired consistency.
- Taste and adjust taco seasoning to suit your heat preference.
Storage
- Refrigerate cooled beef and sauce separately in airtight containers for up to 4 days.
- Reheat gently on the stovetop, stirring often, and add a little milk if the sauce has thickened too much.
Freezing
- Freeze the cooked beef mixture or the sauce separately in freezer bags or containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Flavor variations using existing ingredients only
- Mix some of the cooked beef directly into the Rotel sauce for a saucier taco topping.
- Use more undrained Rotel in the sauce for a chunkier, more tomato forward topping.
- Reduce the milk slightly for a thicker sauce, or increase it for a looser, pourable sauce.
