Ingredients

For the Taco Spaghetti

2 tablespoons olive oil
1 lb (450 g) ground beef
¼ cup (about 40 g) finely diced yellow onion
¼ cup taco seasoning, or the amount recommended on your packet
1 can (10 oz / 283 g) Rotel diced tomatoes with green chilies, including the juices

8 oz (225 g) dry spaghetti noodles
4 oz (115 g) shredded cheddar cheese
2 cups (480 ml) water or low-sodium beef broth, plus more as needed
Salt and black pepper, to taste, if needed

Optional Toppings

Sliced green onions
Diced tomatoes
Sour cream
Sliced jalapeños
Extra shredded cheddar cheese
Crushed tortilla chips

Instructions

Step 1: Brown the Ground Beef

Heat the olive oil in a large, deep skillet or Dutch oven over medium-high heat.

Add the ground beef and cook for approximately 5–7 minutes, breaking it into small crumbles with a wooden spoon as it browns.

Cook until the beef is no longer pink. If there is a large amount of excess grease, carefully drain it, leaving a little in the skillet for flavor.

Step 2: Add the Onion

Add the finely diced yellow onion to the browned beef.

Cook for 2–3 minutes, stirring occasionally, until the onion begins to soften and becomes fragrant.

This adds a subtle sweetness and creates a flavorful base for the taco-seasoned sauce.

Step 3: Add the Taco Seasoning

Sprinkle the taco seasoning over the beef and onions.

Stir well so the meat is evenly coated. Cook for approximately 30 seconds to help release the aroma of the spices.

If your taco seasoning is particularly salty or spicy, start with a little less and adjust the flavor near the end.

Step 4: Add the Rotel Tomatoes and Liquid

Pour the Rotel tomatoes, including their juices, into the skillet.

Add 2 cups of water or beef broth and stir to combine, scraping up any flavorful browned bits from the bottom of the pan.

Bring the mixture to a gentle boil.

The Rotel tomatoes provide a tangy tomato base and a little heat from the green chilies, giving this dish its delicious Tex-Mex character.

Step 5: Add the Spaghetti

Break the spaghetti noodles in half if necessary so they fit comfortably in the skillet.

Add the noodles to the liquid, gently pressing them down so they are mostly submerged. If the noodles are still sticking out above the liquid, add a little more water or broth.

Reduce the heat to medium-low, cover, and simmer for approximately 10–15 minutes, stirring every few minutes to prevent the noodles from sticking together or to the bottom of the skillet.

Cook until the spaghetti is tender but still has a slight bite.

Important: Cooking time can vary by pasta brand and skillet size. Add extra liquid a splash at a time if the sauce becomes too dry before the noodles are cooked.

Step 6: Check the Consistency

Once the spaghetti is cooked, remove the lid and stir everything together.

The sauce should be thick enough to cling to the noodles, with tender beef and tomatoes distributed throughout.

If the mixture looks too watery, simmer uncovered for 1–2 minutes, stirring gently. If it is too dry, add a splash of warm water or broth.

Taste and adjust the seasoning as needed.

Step 7: Add the Cheddar Cheese

Reduce the heat to low.

Sprinkle the shredded cheddar over the spaghetti and stir gently until the cheese melts into the sauce.

For an extra-cheesy finish, reserve a small handful of cheddar to scatter over the top. Cover the skillet for 1–2 minutes to help the cheese melt completely.

Avoid cooking the dish over high heat once the cheese is added, as excessive heat can make the sauce oily or cause the cheese to become stringy.

Step 8: Garnish and Serve

Remove the skillet from the heat and let the spaghetti rest for 1–2 minutes.

Garnish with chopped cilantro, sliced green onions, extra cheddar, or your favorite taco toppings.

Serve hot straight from the skillet, with sour cream and crushed tortilla chips on the side if desired.

Enjoy a cheesy, hearty dinner that combines the comfort of spaghetti with the bold flavors of taco night!

Tips for the Best Taco Spaghetti

Use a large skillet. A wide, deep pan makes it easier to cook the spaghetti evenly and stir without breaking the noodles.
Break the spaghetti if needed. Shorter strands are easier to fit into the skillet and keep submerged.

Stir regularly while the pasta cooks. This prevents the noodles from clumping or sticking to the pan.
Adjust the liquid as you go. Pasta absorbs liquid at different rates, so add extra broth or water whenever necessary.
Use freshly shredded cheddar. It usually melts more smoothly than pre-shredded cheese.

Taste before adding salt. Taco seasoning and cheddar can already provide plenty of seasoning.
Control the heat. Rotel with green chilies adds some spice, but you can choose a mild version if preferred.
Let it rest briefly before serving. The sauce thickens slightly and clings better to the noodles.

Delicious Variations

Creamy Taco Spaghetti

Stir in 2–4 oz (55–115 g) softened cream cheese or ¼ cup heavy cream before adding the cheddar. This creates a richer, creamier sauce.

Spicy Taco Spaghetti

Use hot Rotel, add sliced jalapeños, or sprinkle in a pinch of crushed red pepper flakes for extra heat.

Taco Spaghetti with Black Beans

Add 1 can (15 oz / 425 g) drained and rinsed black beans during the final few minutes of cooking for extra texture and a heartier meal.

Cheesy Mexican Taco Spaghetti

Replace the cheddar with a Mexican-style cheese blend, or combine cheddar with Monterey Jack for a creamy, melty finish.

Vegetable Taco Spaghetti

Add diced bell peppers with the onion or stir in a handful of baby spinach near the end of cooking.

Chicken Taco Spaghetti

Replace the ground beef with ground chicken or chopped cooked chicken. If using cooked chicken, add it with the Rotel and liquid so it warms through without drying out.

Beef and Corn Taco Spaghetti

Stir in ½–1 cup sweet corn during the final 5 minutes of cooking. The corn adds a pleasant sweetness that balances the taco seasoning.

Baked Taco Spaghetti

Transfer the finished spaghetti to an oven-safe dish, top with extra cheddar, and bake at 375°F (190°C) for approximately 10 minutes, until the cheese is melted and bubbly.

What to Serve with Taco Spaghetti

This hearty meal is satisfying on its own, but simple sides can make dinner even better.

Garlic bread: A delicious way to scoop up the cheesy tomato sauce.
Green salad: Adds freshness and balances the richness.
Corn on the cob: Complements the Tex-Mex flavors.
Guacamole and tortilla chips: Bring classic taco-night flavors to the table.
Roasted bell peppers: Add color and a savory vegetable side.

Mexican-style corn salad: Offers a sweet, tangy contrast.

For a fun family dinner, serve the spaghetti with a small topping bar featuring sour cream, jalapeños, cilantro, extra cheese, and crushed tortilla chips.

Make-Ahead and Storage Instructions

Make ahead: For the best pasta texture, prepare the beef and tomato sauce ahead of time, refrigerate it, then reheat and cook the spaghetti shortly before serving.

Refrigerator: Cool leftovers promptly and transfer them to an airtight container within 2 hours. Store at 40°F (4°C) or below and consume within 3–4 days.

Reheating: Warm leftovers in a skillet over medium-low heat with a splash of water or broth. Stir gently until the pasta is hot throughout. You can also microwave individual portions in short intervals, stirring between intervals.

Freezing: You can freeze the finished dish in airtight containers for up to 2 months for best quality, although the spaghetti may become softer after thawing. Thaw overnight in the refrigerator and reheat thoroughly.

Food safety: Because the recipe contains ground beef, ensure the beef is cooked to an internal temperature of 160°F (71°C) before serving.

Frequently Asked Questions

Can I cook the spaghetti separately?

Yes. Cook the spaghetti in a separate pot according to the package directions, then drain and toss it with the prepared beef and tomato sauce. Add a little pasta water if needed to help the sauce cling to the noodles.

Can I use a different pasta shape?

Absolutely! Penne, rotini, macaroni, or shells can all work. Adjust the cooking time and liquid according to the pasta shape and package instructions.

Why is my Taco Spaghetti too dry?

The noodles may have absorbed more liquid than expected. Add warm broth or water a little at a time until the sauce becomes glossy and coats the pasta.

Why is my spaghetti too watery?

Remove the lid and simmer gently for a few minutes, stirring regularly. The sauce will reduce as excess liquid evaporates. Remember that it also thickens slightly as it rests.

Can I use homemade taco seasoning?

Yes. A mixture of chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and black pepper works well. Adjust the amounts to your preferred flavor and heat level.

Can I make this recipe without Rotel?

Yes. Substitute a can of diced tomatoes and add a small amount of diced green chilies, or use regular diced tomatoes for a milder flavor.

Can I make it less spicy for children?

Use mild Rotel or plain diced tomatoes, choose a mild taco seasoning, and skip the jalapeños and red pepper flakes. Serve spicy toppings separately for anyone who wants extra heat.
