Ingredients You’ll Need

Main Ingredients

2 boxes Velveeta Shells & Cheese: These provide the tender pasta shells and creamy cheese sauce that form the base of the casserole. Prepare them according to the package directions before combining them with the beef.
2 pounds ground beef: Lean ground beef is a convenient choice because it provides plenty of savory flavor without leaving excessive grease in the dish.
1 can Ro-Tel tomatoes: Ro-Tel’s diced tomatoes and green chilies add a tangy, slightly spicy kick that gives the casserole its taco-inspired flavor. Choose mild, original, or hot according to your preference.
2 cups shredded cheddar cheese: Cheddar melts over the top to create a golden, bubbly finish. Sharp cheddar adds a stronger cheese flavor, while mild cheddar gives a gentler taste.
Tostitos Crispy Rounds, for serving: These crunchy tortilla chips are perfect for scooping up the creamy pasta and beef.
Salt and black pepper, to taste: Season the beef carefully, remembering that the packaged cheese sauce and cheddar already contain salt.

Optional Ingredients for Even More Taco Flavor

The original recipe is delicious with the ingredients above, but these additions can make it taste even more like a taco-night casserole:

1 packet taco seasoning, or homemade taco seasoning to taste
1 small onion, diced
2 cloves garlic, minced
1 cup drained black beans
1 cup corn kernels
1–2 tablespoons sliced jalapeños
½ teaspoon smoked paprika
Chopped cilantro or green onions for garnish
Sour cream, salsa, or guacamole for serving

My recommendation: Add taco seasoning to the browned beef for a deeper, more recognizable taco flavor. The recipe works without it, but it’s a delicious upgrade.

Equipment You’ll Need

Large pot for cooking the pasta
Large skillet for browning the ground beef
Colander
Large mixing spoon
Greased 9-by-13-inch baking dish
Measuring cups
Aluminum foil, if needed to prevent excessive browning

How to Make Cheesy Beef Taco Pasta Bake

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9-by-13-inch baking dish with cooking spray or a thin coating of oil or butter. This helps prevent sticking and makes serving easier.

Set the prepared baking dish aside while you cook the pasta and beef.

Step 2: Cook the Velveeta Shells and Cheese

Bring a large pot of water to a boil and cook both boxes of Velveeta shells according to the package directions.

Cook the pasta until just tender. Avoid overcooking it because the shells will spend additional time in the oven.

Drain the pasta as directed on the package.

Prepare the cheese sauce according to the package instructions, then combine it with the cooked shells. Keep the mixture warm while you prepare the beef.

Helpful tip: If the pasta finishes before the beef, don’t let it sit uncovered for too long. Stirring it occasionally helps prevent the shells from sticking together.

Step 3: Brown the Ground Beef

Place a large skillet over medium-high heat and add the ground beef.

Break it apart with a wooden spoon or spatula as it cooks. Continue cooking for approximately 8–10 minutes, or until the beef is browned and fully cooked.

If you’re using onion, add it to the skillet during the early part of cooking so it has time to soften. Add minced garlic near the end to prevent it from burning.

Drain excess grease carefully.

For food safety, ground beef should reach an internal temperature of 160°F (71°C).

Step 4: Add the Ro-Tel Tomatoes and Seasoning

Add the can of Ro-Tel tomatoes to the browned beef.

For a stronger taco flavor, stir in taco seasoning according to the packet directions or to taste. If the mixture seems dry, add a small splash of water or beef broth.

Let everything simmer for 2–3 minutes so the flavors combine.

Taste the beef mixture before adding extra salt. The seasoning, tomatoes, and cheese sauce may already provide plenty of flavor.

Step 5: Combine the Beef and Cheesy Pasta

Add the cooked shells and cheese sauce to the skillet if it is large enough, or transfer everything to a large mixing bowl.

Stir in the beef and tomato mixture until the ingredients are evenly distributed.

Make sure each spoonful contains a good balance of creamy shells, seasoned beef, and zesty tomatoes.

If you like a little extra heat, add sliced jalapeños or a pinch of crushed red pepper flakes at this stage.

Step 6: Transfer to the Baking Dish

Spoon the cheesy beef pasta mixture into the prepared baking dish.

Spread it into an even layer with the back of a spoon or spatula.

Sprinkle the shredded cheddar cheese evenly over the top, covering the pasta from edge to edge.

For an especially cheesy topping, you can add a little extra cheddar or mix cheddar with Monterey Jack.

Step 7: Bake Until Hot and Bubbly

Place the casserole in the preheated oven and bake for 15–20 minutes, or until the cheese is melted and the filling is bubbling around the edges.

If you want a more golden top, switch to the broiler for the final 1–2 minutes, watching constantly to prevent burning.

Because the beef and pasta are already cooked, the purpose of baking is to heat everything through and melt the cheese.

For food safety, if the casserole was prepared ahead and refrigerated, reheat it until the center reaches 165°F (74°C).

Step 8: Rest and Serve

Remove the casserole from the oven and let it rest for about 5 minutes.

This short resting period helps the cheese settle slightly and makes serving easier.

Spoon generous portions into bowls or onto plates. Serve with crispy Tostitos rounds on the side, or sprinkle a few crushed chips over each portion just before eating.

For an extra taco-night touch, add sour cream, salsa, chopped cilantro, sliced green onions, or diced avocado.

Get ready for creamy pasta, savory beef, zesty tomatoes, and plenty of melted cheese in every bite!

Expert Tips for the Best Taco Pasta Bake

1. Cook the pasta just until tender. Slightly firm pasta holds up better during baking.

2. Drain the beef well. Excess grease can make the casserole oily and heavy.

3. Add taco seasoning for extra flavor. It brings cumin, chili, garlic, and other familiar taco spices to the beef.

4. Drain watery additions. If using canned corn or beans, drain them well so they don’t dilute the cheese sauce.

5. Use a large mixing bowl. Combining everything thoroughly before baking ensures every serving has beef, pasta, and sauce.

6. Shred your own cheddar if convenient. It often melts more smoothly than pre-shredded cheese.

7. Avoid adding too much extra liquid. The Velveeta sauce should keep the pasta creamy without making it soupy.

8. Cover loosely with foil if needed. If the top browns before the center is hot, cover the dish for the remaining baking time.

9. Add chips just before serving. This keeps them crunchy rather than letting them become soggy in the casserole.

10. Taste before adding salt. Boxed cheese sauce, cheddar, and taco seasoning can all contain significant amounts of sodium.

Delicious Variations and Substitutions

1. Spicy Jalapeño Taco Pasta Bake

Add sliced jalapeños and a pinch of cayenne pepper to the beef mixture. Use hot Ro-Tel if you enjoy a stronger kick.

2. Beef and Black Bean Taco Pasta

Stir in one cup of drained black beans before baking. They add texture, fiber, and extra heartiness.

3. Taco Corn Pasta Bake

Add one cup of drained corn kernels for sweetness and a little extra color.

4. Loaded Nacho Pasta Bake

Top the finished casserole with crushed tortilla chips, sliced jalapeños, diced tomatoes, and green onions just before serving.

5. Extra-Cheesy Taco Pasta

Mix in ½–1 cup of Monterey Jack or mozzarella before transferring the mixture to the baking dish. Keep the cheddar topping for a golden finish.

6. Mild Family-Friendly Version

Choose mild Ro-Tel and skip the hot peppers. Serve salsa and jalapeños on the side so everyone can customize their plate.

7. Ground Turkey Taco Pasta

Replace the ground beef with ground turkey. Cook it thoroughly, season generously, and add a small amount of oil if needed to prevent sticking.

8. Ground Chicken Taco Pasta

Ground chicken is another alternative. Taco seasoning, garlic, and onion help build flavor.

9. Sausage and Beef Taco Pasta

Replace part of the ground beef with cooked, crumbled sausage for a richer, more savory casserole.

10. Onion and Garlic Taco Pasta

Sauté diced onion with the beef and add minced garlic near the end of browning. These aromatics add depth to the sauce.

11. Different Pasta Shapes

You can use elbow macaroni, rotini, penne, or another sturdy pasta shape. Cook the pasta separately and prepare a creamy cheese sauce to replace the boxed shells and cheese.

12. Homemade Cheese Sauce Version

For a from-scratch variation, prepare a cheese sauce using butter, flour, milk, and shredded cheddar or Monterey Jack. Toss it with cooked pasta before combining it with the beef mixture.

13. Salsa Taco Pasta Bake

Replace the Ro-Tel with a similar quantity of drained salsa if that’s what you have available. Choose a thick salsa to avoid adding too much liquid.

14. Vegetarian Taco Pasta Bake

Skip the ground beef and use black beans, pinto beans, or a plant-based ground substitute. Season well and follow the same assembly and baking process.

Make-Ahead Instructions

This taco pasta bake is a convenient option for meal prep.

Cook the pasta and prepare the beef mixture as directed.
Combine the pasta, cheese sauce, beef, and tomatoes.
Transfer the mixture to the baking dish and add the shredded cheddar.
Cover and refrigerate promptly if you’re not baking it right away.
When ready to bake, remove the dish from the refrigerator while the oven preheats, but don’t leave the casserole sitting at room temperature for an extended period.
Bake until hot throughout and the center reaches 165°F (74°C).

A chilled casserole may need additional baking time. If the cheese begins browning too quickly, cover the dish loosely with foil.

For the best texture, add tortilla chips only when serving.

How to Store Leftovers

Allow leftovers to cool briefly, then transfer them to shallow, airtight containers and refrigerate promptly.

Refrigerator: Store for 3–4 days at 40°F (4°C) or below.
Freezer: Freeze in airtight, freezer-safe containers for approximately 2–3 months for best quality.

The cheese sauce may thicken after chilling, and the pasta may absorb some of the moisture. A splash of milk or broth can help restore the creamy texture when reheating.

Store tortilla chips separately so they remain crisp.

How to Reheat Taco Pasta Bake

Oven Method

Preheat the oven to 350°F (175°C).
Transfer the desired portion to an oven-safe dish.
Add a splash of milk or broth if the pasta looks dry.
Cover loosely with foil.
Heat until the center reaches 165°F (74°C), removing the foil toward the end if you want to refresh the cheesy topping.

The time required depends on the portion size and whether the casserole is refrigerated or frozen.

Microwave Method

Place a serving in a microwave-safe dish.
Add a small splash of milk or broth.
Cover loosely with a microwave-safe lid.
Heat in short intervals, stirring between intervals when possible.
Continue until the portion is hot throughout and reaches 165°F (74°C).

Reheating From Frozen

For the best results, thaw the casserole in the refrigerator before reheating. You can also reheat portions directly from frozen in an oven-safe dish, allowing extra time and checking that the center reaches 165°F (74°C).

Avoid repeatedly reheating the entire casserole. Warm only what you plan to eat.
