How to Make Cheesy Rotel Beef Tacos

Step 1: Cook the Beef

Heat the olive oil in a large skillet over medium-high heat.
Add the diced onion and cook for 3–4 minutes, until softened.
Add the ground beef and cook until browned, breaking it apart with a wooden spoon or spatula as it cooks.
Drain excess grease if needed.

Step 2: Add the Rotel

Stir the taco seasoning into the browned beef.
Add the drained Rotel diced tomatoes and green chilies.
Pour in the water or beef broth.
Simmer for 5–7 minutes, stirring occasionally, until the mixture is flavorful and slightly thickened.
Season with salt and black pepper to taste.

Step 3: Make the Cheesy Sauce

Melt the butter in a saucepan over medium heat.
Whisk in the flour and cook for about 1 minute.
Slowly pour in the milk while whisking constantly to keep the sauce smooth.
Continue cooking for 3–5 minutes, until the sauce has thickened.

Step 4: Add the Cheese

Reduce the heat to low.
Gradually stir in the shredded cheddar and Monterey Jack cheese.
Add the taco seasoning and garlic powder.
Stir until the cheese has melted and the sauce is smooth and creamy.

Step 5: Assemble the Tacos

Warm the tortillas in a dry skillet or microwave.
Fill each tortilla with the seasoned beef mixture.
Spoon a generous amount of the creamy cheesy Rotel sauce over the beef.

Step 6: Garnish and Serve

Top the tacos with shredded lettuce, diced tomatoes, red onion and fresh cilantro.
Serve immediately with lime wedges.
Add sour cream if desired.

Serving Suggestions

These cheesy beef tacos are filling on their own, but you can turn them into a complete taco-night spread with simple sides such as:

Mexican-style rice
Black beans
Fresh guacamole
Tomato salsa
Corn salad
Fresh avocado
Extra tortilla chips

Helpful Tips

Don’t overcrowd the beef: Break it into small pieces as it browns so the seasoning distributes evenly.
Whisk the sauce continuously: This helps create a smooth cheese sauce without lumps.
Add cheese over low heat: Lowering the heat before adding the cheese helps keep the sauce creamy.
Warm the tortillas: Warm tortillas are softer and easier to fold around the filling.
Serve immediately: The cheesy sauce is at its best while warm and creamy.

Easy Variations

Make it spicier: Add sliced jalapeños or extra green chilies.
Use ground turkey: Ground turkey can be used instead of beef for a different version.
Add avocado: Diced avocado adds a creamy, fresh topping.
Try different cheese: Pepper Jack can add extra flavour and heat.
Use corn tortillas: Corn tortillas provide a slightly different texture and flavour from flour tortillas.

Storage

Store leftover beef and cheesy sauce separately in airtight containers in the refrigerator. Warm the beef and sauce gently before assembling fresh tacos. Keep the fresh toppings separate and add them just before serving.
