Ingredients

3 pounds ground beef, hearty and versatile, provides the main savory filling.
1–2 tablespoons olive oil, for sautéing the onion and preventing sticking; use 1 tablespoon for lower fat or 2 for richer flavor.
1 medium onion, diced, adds sweetness and texture; yellow or white onion work well.
Taco seasoning, to taste, brings classic taco flavors; start with a few tablespoons and adjust to your liking.
2 tablespoons butter, used to make the roux and add a rich, smooth base to the sauce.
1/3 cup all-purpose flour, thickens the sauce when cooked with butter.
2 1/2 cups milk, creates the creamy sauce; whole milk yields a richer result but lower-fat milk also works.
2 cans (10 oz each) Rotel, undrained, adds diced tomatoes with green chilies for brightness and mild heat; stir straight from the can.

This filling also pairs well with quick breakfast or snack ideas like Cheesy Egg Puffs for a fun leftover use.

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, stirring occasionally so the onion softens evenly. Tip: cook the onion until it just begins to brown if you like a touch of caramelized sweetness.
Brown the beef. Add 3 pounds ground beef to the skillet, breaking it up with a spoon as it cooks. Sprinkle taco seasoning over the meat to taste, then stir to combine. Continue cooking until the beef is fully browned and cooked through, about 8 to 12 minutes. Drain excess fat if desired. Tip: taste a small piece and adjust seasoning before assembling tacos.
Make the roux. In a separate saucepan, melt 2 tablespoons butter over medium heat. Stir in 1/3 cup all-purpose flour and cook, whisking, for 1 minute to remove the raw flour taste. This short cook time keeps the sauce smooth.
Add milk and thicken. Gradually whisk in 2 1/2 cups milk, adding a little at a time and stirring continuously to prevent lumps. Continue stirring until the sauce thickens and coats the back of a spoon, about 4 to 6 minutes. Keep the heat moderate so the milk does not scald. Tip: if the sauce gets too thick, whisk in a splash more milk to reach your desired consistency. For a similar creamy base technique, see Cheesy Garlic Butter Chicken Bowtie Mozzarella Sauce.
Combine with Rotel. Stir the undrained Rotel directly into the thickened milk sauce and mix well until evenly combined. Heat through for 1 to 2 minutes so the flavors meld.
Assemble and serve. Spoon the seasoned beef mixture into taco shells and top with the cheesy Rotel sauce. Serve immediately while warm so the sauce is creamy and the shells stay crisp. Tip: keep the beef and sauce separate until serving if you plan to prepare ahead to avoid soggy shells.

Tips, Storage & Variations

Tips

Brown the beef in batches if your skillet is crowded to ensure even browning.
Taste the beef after adding taco seasoning and adjust salt or spice before assembling.
Keep the beef and cheesy Rotel sauce warm separately until serving to preserve texture.

Storage

Refrigerator: Store beef and cheese Rotel sauce in separate airtight containers for up to 3 to 4 days. Reheat gently on the stove.
Freezing: Both the cooked beef and the sauce freeze well. Cool completely, then freeze in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating slowly on the stove.

Variations using the ingredients on hand

Extra tomato and heat: Use the full two cans of undrained Rotel, and stir in the sauce for a brighter, more tomato-forward topping.
Thicker sauce: Increase the flour slightly by a tablespoon or reduce milk a bit to get a heartier cheese-style sauce.
Milder sauce: Drain some of the Rotel liquid before adding if you want less brightness and heat.
Less fat: Use 1 tablespoon olive oil and a lower fat milk if you prefer a lighter version. For an idea of how this approach adapts to pasta dishes, see a creamy pasta variation.
