Ingredients

• 2.5 pounds ground beef (80/20 blend)
  Provides juicy flavor and enough fat to keep the filling rich and satisfying.

• 1 tablespoon olive oil
  Helps soften the onion and prevents sticking while adding a touch of fruity flavor.

• 1 medium onion, finely diced
  Adds sweetness and aromatic depth when cooked until translucent.

• 2 tablespoons taco seasoning
  Brings classic taco spices to the meat; use more or less to suit your taste.

• 2 tablespoons unsalted butter
  Creates the base for the cheese sauce without adding extra salt.

• 3 tablespoons all-purpose flour
  Thickens the milk into a smooth sauce; whisk in evenly to avoid lumps.

• 2.5 cups whole milk
  Gives the cheese sauce a creamy texture and full-bodied flavor.

• 2 cans (10 oz each) Rotel (diced tomatoes with green chilies), undrained
  Adds tomato brightness and mild heat directly into the sauce, no draining needed.

• 2.5 cups freshly shredded cheddar cheese
  Melts into the sauce for a rich, gooey finish; freshly shredded melts best.

• 1/3 cup sour cream
  Adds tang and silkiness when folded into the finished filling.

• Hot sauce (optional)
  For anyone who wants extra heat, add a few dashes to taste.

• Salt and black pepper to taste
  Fine-tune seasoning at the end for balanced flavor.

Step-by-step Instructions

1. Heat the olive oil in a large skillet over medium heat. Add the finely diced onion and cook, stirring occasionally, until the onion is translucent, about 4 to 5 minutes. Tip: cook until the edges just begin to soften for the best sweet-aromatic base.

2. Add the ground beef to the skillet and cook until browned, breaking it apart with a spoon as it cooks. Stir in the 2 tablespoons taco seasoning and mix well so the spices coat the meat evenly.

3. While the beef is browning, melt the unsalted butter in a separate saucepan over medium heat. Stir in the all-purpose flour and cook, stirring, for about 1 minute to form a roux.

4. Gradually whisk the whole milk into the roux, adding a little at a time to prevent lumps. Cook the mixture, whisking often, until it thickens, about 4 to 6 minutes.

5. Stir the undrained Rotel into the thickened milk mixture, then add the freshly shredded cheddar cheese. Stir until the cheese is melted and the sauce is smooth.

6. Pour the meat mixture into the skillet with the cheese sauce or combine the cheese sauce with the meat in the saucepan, mixing well so the beef is fully coated.

7. Stir in the 1/3 cup sour cream and hot sauce if using. Taste and season with salt and black pepper to your preference.

8. Serve the cheesy Rotel beef in taco shells or tortillas and garnish with any additional toppings you enjoy. Tip: warm your shells or tortillas briefly before serving so the filling stays hot and the cheese stays melty.

Tips, Storage & Variations

• Tips: Use freshly shredded cheddar for the smoothest melt and best texture. Cook the milk mixture slowly and whisk constantly to avoid lumps in the sauce. Adjust the taco seasoning to match your heat preference.
• Storage: Refrigerate leftover filling in an airtight container for up to 4 days. Reheat gently on the stove over low heat, stirring occasionally, or warm in the microwave in short bursts.
• Freezing: Cool completely, then freeze the combined meat and cheese filling in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Variations using existing ingredients only: Increase the taco seasoning for a bolder spice profile, stir in extra hot sauce for more heat, or fold in a bit more sour cream for an even creamier filling.

Frequently Asked Questions

Q: Can I make the cheese sauce ahead of time?
A: Yes. Make the cheese sauce and store it in the refrigerator up to 2 days, then gently reheat before combining with the meat.

Q: Is whole milk necessary?
A: Whole milk gives the richest, creamiest sauce. Lower-fat milk will work but the sauce will be less rich.

Q: How can I reduce spice?
A: Use less taco seasoning and omit any added hot sauce. The Rotel already adds some mild heat, so taste as you go.

Q: Will pre-shredded cheese work?
A: You can use pre-shredded cheese, but freshly shredded cheddar melts more smoothly and gives a better texture.

Q: How should I reheat leftovers for tacos?
A: Reheat the filling in a skillet over low heat, stirring to restore creaminess, then warm shells or tortillas separately.

People Also Ask

Q: What type of ground beef is best for tacos?
A: An 80/20 blend balances flavor and juiciness, which works very well in this recipe.

Q: Can I use a different cheese with the Rotel?
A: This recipe calls for cheddar, which melts well, but other melters can be used if you have them on hand.

Q: Should I drain the Rotel before adding it?
A: Do not drain the Rotel for this recipe; the liquid helps loosen the sauce and adds flavor.

Q: Can this filling be used for nachos instead of tacos?
A: Yes, spoon the hot filling over tortilla chips and add a little extra cheese if desired.

Q: How long does the cheese sauce take to thicken?
A: After adding milk to the roux, expect the sauce to thicken in about 4 to 6 minutes over medium heat.

Q: Is sour cream required in the filling?
A: Sour cream adds tang and creaminess but is optional if you prefer to skip it.

Q: Can I double the recipe for a crowd?
A: You can double quantities, but use a larger skillet and saucepan to keep even cooking.

Q: What is the best way to season to taste?
A: Add taco seasoning to the meat as directed, then adjust salt, pepper, and hot sauce after combining so you can fine-tune the final flavor.
