This cheesy one pot taco mac is a weeknight lifesaver when everyone is hungry and you need something filling fast. The combination of ground beef, spices, and gooey cheese all come together in one pot for a dish that is big on flavor and low on cleanup. Every bite is savory and rich with a little kick from the green chilies and taco seasoning, making it a family favorite.
I first pulled this together on a rainy Thursday when I had almost nothing in the fridge. Now it is my go to whenever my family needs something comforting but I am short on time and energy.
Ingredients
- Ground beef: adds rich flavor and a hearty base try to use fresh and lean beef for best texture
- Yellow onion: gives sweet undertones and aroma go for firm onions without soft spots

- Diced tomatoes with green chilies: provide zesty tang and gentle heat choose Rotel or any brand with quality tomatoes and visible chili bits
- Taco seasoning: gives the classic spicy flavor packets are handy but homemade blends work too
- Tomato sauce: helps tie everything together go for smooth and pure tomato sauce

Step-by-Step Instructions
- Sauté the Aromatics:
- Start by heating your large skillet over medium high heat Toss in the diced onion and bell pepper Stir regularly until the onions turn fragrant and translucent The gentle heat draws out their sweetness while softening everything
- Brown the Meat:
- Crumble in the ground beef Mix with the veggies and let everything cook together until you do not see any more pink bits You want the beef nicely browned but not crispy Drain off any excess grease so your final dish is not oily
- Season the Base:
- Sprinkle in the whole packet of taco seasoning The spices should coat all the beef and vegetables Stir for a minute to bloom the flavors before adding the liquids This step gives you the classic taco aroma right from the pan
- Simmer with Liquids and Pasta:
- Pour the can of diced tomatoes with green chilies into the skillet followed by tomato sauce beef broth and whole milk Stir it all up until combined Fold in the shell pasta so it is covered with liquid Bring to a low simmer and cover your skillet Let it gently cook for about ten to fifteen minutes Stir a few times so the shells do not stick to the bottom Test the pasta at the ten minute mark you want it perfect al dente
- Make it Cheesy:
- Once your pasta is cooked scatter in the shredded cheddar cheese Stir until the cheese is fully melted and the sauce is smooth and creamy Serve piping hot right from the pan with extra cheese if you like

My favorite ingredient is always the diced tomatoes with green chilies because they bring the perfect pop of flavor without needing to chop extra veggies Every time I make this dish with my kids we argue over who gets to eat the crispy cheese bits stuck to the pan
