One-Pot Taco Spaghetti combines seasoned ground beef, diced tomatoes with green chiles, tomato paste, spaghetti, and two cheeses in the same pot. I like this style of dinner because the pasta cooks directly in the seasoned liquid, so the sauce and noodles come together instead of feeling like two separate parts.
The main thing I watch is the liquid level while the spaghetti cooks. We want enough water for the pasta to soften, but not so much that the finished dish turns soupy. The tomato paste helps thicken the cooking liquid as the noodles absorb it.
Why This Works as a One-Pot Dinner
The ground beef is browned first, then the taco seasoning goes into the same pot. After that, the tomatoes, tomato paste, dry spaghetti, and water all cook together. That means the starch released by the pasta stays in the sauce and helps give it body.
I add the cheese only after the pasta is tender. This keeps the cheddar and mozzarella creamy instead of letting them cook too long and become oily.
Ingredients
- 1 tablespoon olive oil
- 1 pound ground beef
- 1 (1.25-ounce) package taco seasoning
- 1 (10-ounce) can mild diced tomatoes with green chiles
- 1 tablespoon tomato paste
- 8 ounces spaghetti
- 3 cups water
- 1/2 cup shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 1 Roma tomato, diced, optional for serving
- 2 tablespoons chopped fresh cilantro, optional for serving
How to Make One-Pot Taco Spaghetti
- Heat the olive oil in a large pot or Dutch oven over medium-high heat.
- Add the ground beef and cook for 3 to 5 minutes, breaking it into small crumbles as it browns. Drain excess fat if needed.
- Stir in the taco seasoning so it coats the beef evenly.
- Add the diced tomatoes with green chiles, tomato paste, dry spaghetti, and 3 cups of water.
- Bring the mixture to a boil. Cover, reduce the heat, and simmer for about 13 to 16 minutes, stirring occasionally so the spaghetti does not stick together or catch on the bottom.
- When the pasta is tender and most of the liquid has been absorbed, remove the pot from the heat.
- Sprinkle the cheddar and mozzarella over the top. Cover the pot for about 2 minutes, or until the cheese melts.
- Serve with diced Roma tomato and chopped cilantro if desired.
What If the Pasta Looks Too Dry?
Different spaghetti brands absorb liquid at slightly different rates. If the noodles are still firm but the pot looks dry, I add a small splash of hot water, stir, cover, and continue cooking. It is easier to add a little liquid than to recover from a watery finished sauce.
What If It Looks Too Soupy?
Leave the lid off for the last few minutes and stir gently while the excess liquid reduces. The sauce should cling to the noodles before the cheese goes on.
Serving Ideas
This is already a full beef-and-pasta dinner, so I keep the sides simple. A green salad, corn, sliced avocado, or a spoonful of sour cream works well. If your family likes more heat, add jalapeños or hot sauce at the table rather than increasing the spice for the entire pot.
Leftovers
Refrigerate leftovers in a covered container. The pasta continues to absorb sauce as it sits, so I add a small splash of water or broth when reheating and warm it gently until hot.
Common Questions
Do I cook the spaghetti first?
No. The dry spaghetti cooks directly in the seasoned tomato mixture and water.
Can I use a different cheese?
Yes. A Mexican-style cheese blend can replace the cheddar and mozzarella if you prefer. Add it after the pasta finishes cooking so it melts smoothly.
