Ingredients You’ll Need
The ingredient list is short, but each item has an important role. Lean ground beef provides the main protein, onion adds savory sweetness, and taco seasoning brings the signature spice blend without requiring a long list of individual seasonings.
- Ground beef and onion: Cook them together so the onion softens while the beef browns.
- Taco seasoning: One envelope, about 1 ounce, seasons the entire skillet.
- Tomato soup: Use one 10.5–10.75-ounce can undiluted for a thick, creamy tomato base.
- Diced tomatoes with green chiles: Keep the can undrained because the liquid helps loosen the sauce and carries extra flavor.
- Short pasta: Eight ounces of elbow macaroni or another short shape works well because it holds the sauce.
- Sharp cheddar: One and a half cups are divided between the pasta mixture and the casserole topping.
For serving, set out sour cream, sliced green onions, chopped tomatoes, cilantro, jalapeños, or crushed tortilla chips. A topping bar lets everyone customize the casserole, from cool and creamy to fresh, spicy, or crunchy.

How to Make It Step-by-Step
Step 1: Heat your oven to 350°F and lightly grease a 9-by-13-inch baking dish or a similar 2 1/2-quart casserole dish. Having the dish ready before mixing keeps the cooking process organized and makes transferring the pasta simple.
Step 2: Bring a pot of salted water to a boil and cook the elbow macaroni or short pasta according to the package timing. Stop cooking 1–2 minutes before al dente, then drain well; the pasta will continue cooking in the casserole.
Step 3: While the pasta cooks, place the lean ground beef and diced onion in a large skillet over medium heat. Cook for about 6–8 minutes, stirring and breaking the beef into crumbles, until the beef is browned and the onion is tender.
Step 4: Drain the excess fat from the skillet thoroughly, then stir in the taco seasoning, condensed tomato soup, and undrained diced tomatoes with green chiles. Let the mixture simmer for 3–5 minutes so the flavors combine; add up to 1/4 cup water only if the sauce looks overly thick.
Step 5: Add the drained pasta to the skillet and stir in about 1 cup of the shredded cheddar cheese. Mix gently until the pasta is evenly coated and the cheese begins to blend into the warm sauce.
Step 6: Spoon the pasta mixture into the greased baking dish and spread it into an even layer. Sprinkle the remaining 1/2 cup cheddar over the top, then cover the dish loosely with foil.
Step 7: Bake covered for 15 minutes to warm the center without drying the pasta. Remove the foil and bake for another 5–10 minutes, until the casserole is hot and the cheese has melted into a glossy topping.
Step 8: Rest the casserole for 5 minutes before serving. This short pause helps the sauce settle so each scoop holds together, then add sour cream, green onions, cilantro, jalapeños, chopped tomatoes, or tortilla chips.
Pro Tips for the Best Casserole
The most important texture tip is to undercook the pasta slightly. Pasta that is fully cooked before baking can become soft after it absorbs the sauce and spends time in the oven, while pasta cooked 1–2 minutes shy of al dente stays pleasantly tender.
Drain the beef thoroughly after browning, especially if your ground beef releases a generous amount of fat. At the same time, resist the urge to drain the tomatoes with green chiles, since their seasoned liquid helps create the casserole sauce.
Shred cheddar from a block when possible for especially smooth melting. Pre-shredded cheese is convenient, but freshly shredded cheese often melts more evenly across the top.
Keep the foil loose rather than pressing it directly onto the cheese. The covered baking time warms the casserole gently, while the uncovered finish allows the cheddar to melt and take on a lightly golden appearance.
For a different protein, ground turkey or ground chicken can replace the beef. Monterey Jack, pepper Jack, or a Mexican cheese blend can replace some or all of the cheddar, depending on whether you prefer a milder, spicier, or more varied cheese flavor.

Serving, Storage, and Reheating
Serve this casserole as soon as it has rested, while the cheese is still soft and the sauce is warm. A simple green salad, steamed vegetables, or crisp corn makes a fresh contrast to the rich pasta.
For a taco bar-style presentation, arrange the toppings in small bowls. Sour cream cools the chile flavor, cilantro and green onions add freshness, chopped tomatoes bring brightness, jalapeños add heat, and crushed tortilla chips provide a welcome crunch.
Transfer leftovers to a covered container and refrigerate them promptly. Reheat individual portions gently until hot, adding a small splash of water if the pasta has absorbed much of the sauce.
The casserole is also a useful make-ahead dinner. Assemble it in the baking dish, cover it, and refrigerate it until you are ready to bake; allow additional time for the chilled center to heat through and check that it is hot before serving.

Easy Variations to Try
The published versions of this casserole vary, so there is room to adapt it while keeping the same comforting structure. A common alternative to condensed tomato soup is 1 can of 8-ounce tomato sauce plus 1/2 cup beef broth, creating a slightly lighter sauce with a more pronounced tomato profile.
You can also change the pasta shape, provided you use a short variety that can capture the sauce. Elbows are classic, but small shells, rotini, or penne can work well; keep the amount at 8 ounces for the stated sauce ratio.
Some recipes use 10–12 ounces of pasta for a larger casserole. If you increase the pasta, increase the sauce and cheese slightly as well so the finished dish does not become dry or under-seasoned.
For a more substantial topping, add crushed tortilla chips just before serving rather than baking them under the foil. You can also scatter a few over the cheese during the uncovered baking time, watching closely so they do not become too dark.
If you are serving several comfort-food sides, these cheesy garlic scalloped potatoes are another rich and delicious option, though a crisp salad may be better when serving this pasta as the main dish.
