This one pot cheesy taco mac rescued our dinner routine during the busiest family weeks. When all I want is a filling meal with minimal cleanup and guaranteed smiles, this dish delivers. It is fast, comforting, and hearty enough that nobody leaves the table hungry.
I made this once when I was short on time and patience, and now my family asks for it on repeat. Even my neighbor’s picky kids request it when I babysit after school.
Ingredients
- Ground beef: with a ratio of 80 percent lean for rich flavor without too much grease
- Diced tomatoes with chilies: like the Rotel brand give just enough kick and juiciness
- Shell pasta: is perfect because its curves trap every bit of cheesy sauce
- Sharp cheddar cheese: melts beautifully and stands up to the bold flavors
- Whole milk: provides creaminess instead of wateriness that skim milk can cause
- Taco seasoning packet: saves time but a quality blend makes everything taste even better
- Onions: look for vibrant fresh onions
- Bell peppers: look for colorful bell peppers for sweetness and depth
Step-by-Step Instructions
- Building The Meat Base:
- Start by heating your largest skillet over medium-high. Toss in diced onions and bell peppers together with the ground beef. Stir and break up the meat as it cooks until no pink remains and the vegetables are soft. Pour off extra grease so the finished dish is not oily.
- Adding The Seasonings:
- Sprinkle your taco seasoning right onto the meat and vegetable mixture. Toss everything to coat well so those classic taco spices infuse every bite.
- Creating The Liquid Base:
- Add diced tomatoes with green chilies tomato sauce beef broth and whole milk straight into the skillet. Stir to combine then pour in the shell pasta making sure every piece is nestled in liquid.
- Simmering To Perfection:
- Cover the skillet and bring to a gentle simmer. Lower the heat so you do not scorch anything. Cook for about ten to fifteen minutes stirring now and then so the noodles do not stick. The pasta should be tender and most of the sauce absorbed.
- Finishing With Cheese:
- Take the skillet off the heat. Stir in shredded cheddar cheese bit by bit until the sauce turns luscious and smooth.
- Serving It Right:
- Ladle up while everything is hot and melty for the best experience. Extra toppings like salsa or sour cream are always welcome.

My favorite part is the way shell pasta hugs all that creamy cheese sauce. Once my daughter asked if we could make this for her sleepover because it tastes like taco night and mac and cheese all at the same time. The joy on her face when her friends loved it too is why I keep cooking it.
Storage Tips
Keep extra portions in a tightly covered dish in your refrigerator for up to four days. Warm in the microwave or on the stove with a bit of milk to make the cheese sauce silky again. For longer storage freeze for up to three months. The pasta softens a little after thawing but the flavor is still cozy and delicious.
Ingredient Substitutions
Ground turkey chicken or plant-based crumbles can be used in place of beef with great results. Switch shell pasta for penne or elbow macaroni if that is what you have. Add-ins like black beans or corn blend in perfectly if your family enjoys them. For more heat try swapping sharp cheddar for pepper jack cheese.
Serving Suggestions
Serve with tortilla chips for extra crunch or pile on shredded lettuce and sliced jalapeños for a taco salad vibe. A simple green salad balances the richness nicely. Leftovers make a quick lunch or filling next-day snack.

Cultural Context
This dish is inspired by American skillet classics that borrow taco flavors from Mexican cuisine and combine them with the comfort of pasta. It is a modern take on both taco night and macaroni and cheese—a true weeknight mashup that speaks to busy family tables.
