Ingredients

  • 1 lb 85% lean ground beef
  • 1 small yellow onion, diced
  • 3 garlic cloves, minced
  • 1 tbsp taco seasoning (or 2 tsp chili powder + 1 tsp cumin + 1/2 tsp smoked paprika + 1/2 tsp salt)
  • 1 (10 oz) can Rotel diced tomatoes with green chiles, undrained
  • 1 (8 oz) can tomato sauce
  • 2 1/2 cups low-sodium beef broth
  • 1 1/2 cups whole milk
  • 12 oz elbow macaroni (uncooked)
  • 1/2 tsp kosher salt
  • 1/4 tsp black pepper
  • 8 oz sharp cheddar, freshly shredded
  • 4 oz Monterey jack or pepper jack, freshly shredded
  • For serving: chopped cilantro, sliced jalapeños, diced tomatoes, sour cream, lime wedges

Instructions

  1. 1

    Heat a large Dutch oven over medium-high heat. Add the ground beef and onion; cook, breaking up the meat, until browned, about 6 minutes. Drain excess fat if needed.

  2. 2

    Stir in the garlic and taco seasoning and cook 1 minute until fragrant.

  3. 3

    Add the Rotel, tomato sauce, beef broth, milk, salt, and pepper. Stir well and bring to a boil.

  4. 4

    Stir in the uncooked macaroni. Reduce the heat to a low simmer and cook uncovered for 12–14 minutes, stirring every 2–3 minutes, until the pasta is tender and most of the liquid is absorbed into a thickened sauce.

  5. 5

    Remove from heat and let it sit 1 minute. Stir in the cheddar and Monterey jack one handful at a time until melted and glossy.

  6. 6

    Taste and adjust salt. Top with cilantro, jalapeños, diced tomatoes, and a squeeze of lime. Serve straight from the pot.

Frequently Asked Questions

Can I use ground turkey or chicken instead of beef?+

Yes — 93% lean ground turkey or chicken works great and saves about 60 calories per serving. Add 1 extra tsp of oil when browning to compensate for the lower fat content.

What's the best pasta for one pot taco mac and cheese?+

Elbow macaroni is classic and cooks in the same 12–14 minutes the sauce needs to reduce. Small shells and rotini also work perfectly. Avoid quick-cook or gluten-free pasta unless you adjust the liquid ratio.

How do I keep the pasta from sticking in one pot?+

Stir every 2–3 minutes as it simmers and make sure you're at a gentle simmer, not a hard boil. The starch that releases is what makes the sauce silky — you want it in the pot, not stuck to the bottom.

Can I make this dairy-free?+

Swap the milk for full-fat oat milk or unsweetened almond milk, and use a good-quality shredded dairy-free cheese blend. It won't be quite as creamy but still delivers on flavor.

What's the difference between taco mac and cheese and Hamburger Helper?+

Homemade taco mac and cheese uses real shredded cheddar, fresh aromatics, and real tomatoes — no seasoning packet or dehydrated cheese powder. It takes 5 extra minutes and tastes ten times better.

How do I turn leftovers into a new meal?+

Reheat with a splash of milk, then wrap in a large flour tortilla with extra cheese and crisp on both sides in a skillet for a taco mac quesadilla. Kids go wild for these.

Can I make it in the Instant Pot?+

Yes. Sauté the beef and aromatics, then add all liquid + pasta, seal, and pressure cook on High for 4 minutes with a 5-minute natural release. Stir in cheese off-heat.
