2 tablespoons butter, for the roux, gives a buttery flavor and helps thicken the sauce.

2 1/2 cups milk, creates a creamy base for the cheese-style Rotel sauce, use whole milk for best richness.

Step-by-Step Instructions

Heat the skillet. In a large skillet, warm 1 to 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté until translucent, about 4 to 6 minutes. Tip: Stir occasionally to prevent browning, you want soft, sweet onions.
Brown the beef. Add the ground beef to the skillet, breaking it up as it cooks. Sprinkle taco seasoning over the meat and stir to combine. Cook until browned, about 8 to 12 minutes, and drain excess fat if desired. Tip: Taste a small piece and adjust taco seasoning if needed.
Make the roux. In a saucepan, melt 2 tablespoons butter over medium heat. Stir in 1/3 cup all-purpose flour and cook, stirring, for 1 minute to remove the raw flour taste.
Add milk and thicken. Gradually whisk in 2 1/2 cups milk, stirring continuously until the sauce thickens, about 4 to 6 minutes. Keep the heat moderate so the sauce does not scorch.
Combine with Rotel. Stir in the two undrained 10 oz cans of Rotel into the thickened sauce and heat through for 1 to 2 minutes, stirring so the mixture is smooth and warmed.
Assemble and serve. Spoon the seasoned beef mixture into taco shells and top with the cheesy Rotel sauce. Serve immediately while hot so the sauce is creamy and the tacos are at their best.

Tips, Storage & Variations

Tips: Brown the beef in batches if your skillet is crowded to ensure even browning. Keep the sauce on medium heat and whisk constantly as you add milk to avoid lumps.
Storage: Refrigerate assembled tacos for up to 2 days, though texture is best fresh. Store beef and Rotel cheese sauce separately in airtight containers for up to 4 days, then reheat together before serving.
Freezing: Freeze the seasoned beef or the Rotel cheese sauce individually in airtight, freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stove.
Flavor variations using only existing ingredients:
- Increase the amount of Rotel for extra tomato and chile brightness.
- Add more taco seasoning for bolder, spicier taco flavor.
- Thin the sauce with a splash more milk if you prefer a looser, pourable topping.
