Ingredients

2 tablespoons olive oil
1 lb (450 g) ground beef
¼ cup finely chopped yellow onion
¼ cup taco seasoning, or adjusted to taste
1 can (10 oz/283 g) Rotel diced tomatoes with green chiles

8 oz (225 g) spaghetti noodles
4 oz (115 g) shredded cheddar cheese

Optional Additions

½ cup reserved pasta water or beef broth, as needed
½ teaspoon garlic powder for extra savory flavor
¼ teaspoon black pepper, to taste
Sliced green onions or fresh cilantro for garnish
Sour cream, sliced jalapeños, or crushed tortilla chips for serving

Seasoning note: A quarter cup of taco seasoning can be quite strong, especially if using a salty store-bought blend. Start with 2 tablespoons, taste the sauce, and add more as needed.

Instructions

Step 1: Cook the Spaghetti

Bring a large pot of salted water to a boil.

Add the spaghetti noodles and cook according to the package instructions until al dente. The noodles should be tender but still have a little bite, as they will be tossed with the hot sauce later.

Before draining, reserve about ½ cup of pasta water. This starchy water can help loosen the sauce and make it cling to the spaghetti.

Drain the noodles and set aside. Avoid rinsing them, as the remaining starch helps the sauce adhere.

Step 2: Sauté the Onion

While the pasta cooks, heat the olive oil in a large skillet over medium-high heat.

Add the finely chopped yellow onion and sauté for approximately 2–3 minutes, stirring occasionally, until softened and fragrant.

The onion adds a little sweetness and savory depth that balances the taco seasoning and zesty tomatoes.

Step 3: Brown the Ground Beef

Add the ground beef to the skillet with the onion.

Use a wooden spoon or spatula to break the beef into small crumbles. Cook for approximately 6–8 minutes, stirring occasionally, until browned and no longer pink.

Drain excess grease if necessary, leaving a little behind for flavor.

For food safety, cook ground beef to an internal temperature of 160°F (71°C).

Step 4: Add the Taco Seasoning

Sprinkle the taco seasoning over the browned beef and stir thoroughly.

Cook for about 30 seconds, allowing the spices to coat the meat and release their aroma.

If you’re using garlic powder or black pepper, add them now.

Pour in the can of Rotel tomatoes with their juices and stir to combine. The diced tomatoes and green chiles provide acidity, moisture, and a gentle kick of heat.

Step 5: Simmer the Taco Sauce

Reduce the heat to medium and let the beef and tomato mixture simmer for approximately 3–5 minutes, stirring occasionally.

The tomatoes will soften slightly, and the seasoning will blend into the beef to create a flavorful sauce.

If the mixture looks too thick or dry, add a splash of reserved pasta water or beef broth. Start with 2–3 tablespoons and add more as needed.

Taste the sauce before adding extra taco seasoning or salt, since seasoning blends vary in saltiness and heat.

Step 6: Combine the Spaghetti and Sauce

Add the cooked spaghetti directly to the skillet.

Using tongs or two large spoons, toss the noodles with the seasoned beef and tomato mixture until everything is evenly coated.

Continue tossing over low heat for 1–2 minutes, allowing the spaghetti to absorb some of the sauce.

If the mixture seems dry, gradually add a little more reserved pasta water or broth until the sauce reaches your preferred consistency.

Step 7: Add the Cheddar Cheese

Sprinkle the shredded cheddar cheese over the spaghetti.

Toss gently until the cheese melts into the hot pasta, creating a rich, cheesy finish.

For an extra-cheesy presentation, reserve a small handful of cheddar, sprinkle it over the top, and cover the skillet for 1–2 minutes until the cheese melts.

Remove the skillet from the heat once the cheese is melted and the dish is piping hot.

Step 8: Garnish and Serve

Transfer the Taco Spaghetti to serving plates or bring the skillet straight to the table.

Garnish with sliced green onions or chopped cilantro if desired. Serve with a dollop of sour cream, sliced jalapeños, or crushed tortilla chips for extra flavor and texture.

Enjoy the delicious combination of seasoned beef, zesty tomatoes, tender pasta, and gooey cheddar in every bite!

Expert Tips for the Best Taco Spaghetti

Cook the pasta al dente. Slightly firm spaghetti holds its shape better when tossed with the sauce.

Brown the beef well. Proper browning develops a deeper, more savory flavor than simply steaming the meat.

Adjust the seasoning gradually. Taco seasoning blends differ in saltiness and spice, so begin with a smaller amount and taste before adding more.

Use the Rotel juices. The liquid from the tomatoes helps create the sauce and distributes the tomato and green chile flavor throughout the dish.

Reserve the pasta water. Its starch helps loosen the sauce while allowing it to cling to the spaghetti.

Shred the cheddar yourself. Freshly shredded cheddar generally melts more smoothly than many pre-shredded varieties.

Don’t overcook the cheese. Stir it in at the end and remove the skillet from the heat once it has melted for a creamy finish.

Serve immediately. Pasta continues absorbing liquid as it rests, so the dish tastes best while hot and freshly combined.

Delicious Variations

🌶️ Spicy Taco Spaghetti

Add sliced jalapeños, extra Rotel with hot green chiles, or a pinch of cayenne pepper for a spicier version. Adjust the heat gradually so it doesn’t overpower the other flavors.

🧀 Extra-Cheesy Taco Spaghetti

Combine cheddar with Monterey Jack or mozzarella. Sprinkle additional cheese over the top and cover the skillet briefly until melted and stretchy.

🍅 Creamy Taco Spaghetti

Stir in 2–4 tablespoons of cream cheese or a splash of heavy cream at the end of cooking for a richer, creamier sauce.

🫘 Beef and Black Bean Taco Spaghetti

Add ½ cup rinsed black beans to the beef and tomato mixture. They make the dish heartier and complement the taco seasoning beautifully.

🌽 Taco Spaghetti with Corn

Stir in ½–1 cup corn kernels with the Rotel tomatoes. Corn adds a touch of natural sweetness and creates a colorful, family-friendly variation.

🫑 Vegetable-Packed Taco Spaghetti

Add diced bell pepper with the onion and cook until softened. You can also stir in chopped spinach near the end for extra color.

🍗 Ground Turkey Taco Spaghetti

Replace the ground beef with ground turkey for a lighter variation. Brown thoroughly, season well, and cook the turkey to an internal temperature of 165°F (74°C).

🥘 One-Pot Taco Spaghetti

For a one-pot variation, brown the beef and onion in a large, deep skillet, then add the Rotel tomatoes, taco seasoning, approximately 3 cups of broth or water, and broken spaghetti noodles. Simmer gently, stirring frequently, until the pasta is tender, adding more liquid as needed. Cooking time and liquid requirements may vary by noodle brand, so check the pasta regularly. Stir in the cheddar at the end.

What to Serve with Taco Spaghetti

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

Garlic bread: Perfect for scooping up the cheesy taco sauce.
Fresh green salad: Provides a refreshing contrast to the savory beef.

Corn on the cob: Adds sweetness that complements the taco seasoning.
Guacamole and tortilla chips: Bring extra Mexican-inspired flavor to the meal.
Roasted vegetables: A simple way to add color and balance.

Mexican-style street corn: A delicious, creamy side for a Tex-Mex-inspired dinner.

For a fun taco-night dinner, set out small bowls of sour cream, shredded cheese, chopped cilantro, jalapeños, and crushed tortilla chips so everyone can customize their plate.

Make-Ahead and Storage Instructions

Can You Make Taco Spaghetti Ahead?

Yes. You can brown the beef with the onion and taco seasoning in advance, then refrigerate it in a covered container. When you’re ready to eat, heat the beef mixture with the Rotel tomatoes, cook the spaghetti, and combine everything with the cheese.

For the best texture, cook the pasta shortly before serving.

Refrigerator Storage

Allow leftovers to cool slightly and transfer them to an airtight container within 2 hours of cooking.

Store in the refrigerator at 40°F (4°C) or below and enjoy within 3–4 days.

Reheating

Place the spaghetti in a skillet over medium-low heat with 1–2 tablespoons of water or broth.

Stir gently until heated throughout, adding more liquid if needed to loosen the sauce. You can also reheat individual portions in the microwave, stirring halfway through for even heating.

Reheat leftovers to an internal temperature of 165°F (74°C).

Freezing

Taco Spaghetti can be frozen, although the pasta may become softer after thawing.

Cool the dish completely, portion it into freezer-safe containers, and freeze for up to 2 months for best quality. Thaw overnight in the refrigerator and reheat thoroughly with a splash of broth or water.

Frequently Asked Questions

Can I use a different type of pasta?

Absolutely! Penne, rotini, shells, or fettuccine can all work well. Cook the pasta according to the package instructions and adjust the amount of sauce as needed.

Is Taco Spaghetti spicy?

It depends on your taco seasoning and the type of Rotel tomatoes used. For a milder dish, choose mild Rotel and start with less taco seasoning. For extra heat, add hot green chiles or jalapeños.

Why is my Taco Spaghetti dry?

The pasta may have absorbed too much liquid, or the sauce may not have had enough moisture to begin with. Stir in reserved pasta water or beef broth, a tablespoon at a time, until the spaghetti is coated in a saucy mixture.

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 quantities to your taste and add gradually.

Can I use ground chicken or turkey?

Yes. Both are suitable alternatives to ground beef. Because poultry is leaner, you may need a little extra olive oil to brown it well. Cook ground poultry to 165°F (74°C).

Can I make this dish without Rotel?

Yes. Use a can of diced tomatoes and add a small amount of diced green chile or jalapeño. If you prefer a milder flavor, plain diced tomatoes work well too.

How can I make it less salty?

Choose a low-sodium taco seasoning, use less seasoning initially, and avoid adding extra salt until you’ve tasted the finished sauce. Using unsalted or low-sodium broth can also help.

Can I make it ahead for a potluck?

Yes. Prepare it shortly before the gathering if possible, and keep it hot for serving or refrigerate it promptly if making it ahead. Because it contains cooked meat and cheese, don’t leave it at room temperature for more than 2 hours.
