My favorite part of Taco Spaghetti is the mix of familiar pasta and bold taco flavor in the same bowl. Ground beef, tomatoes, green chilies, and two kinds of cheese make a hearty dinner that feels easy and comforting.

The first time I tried this recipe, I loved how it brought tacos and spaghetti together. Fresh toppings like cilantro, sour cream, and diced avocado are a lovely finishing touch, especially when each person can choose what goes on their plate.

This version cooks the spaghetti in its own pot while the beef sauce simmers in a deep skillet. That keeps the pasta texture easy to manage and gives the tomato juices time to reduce. Plan on about 40 minutes from preparation to serving, with the pasta and sauce cooking at the same time.

Why This Dish Is Great

• Two familiar favorites: Taco spices and spaghetti turn everyday ingredients into a satisfying change from regular pasta sauce.
• A filling dinner: Beef, pasta, and cheese make six portions that pair well with a simple vegetable side.
• Easy pantry ingredients: Canned tomatoes, broth, and a seasoning packet keep preparation straightforward.
• Flexible heat: Choose a mild or hotter can of tomatoes with green chilies to suit your table.
• Fresh finishing touches: Cool avocado and sour cream balance the warm, savory sauce.
• Useful leftovers: Individual portions reheat well when stored promptly and topped after reheating.

What Is the Best Ground Beef to Use?

Choose ground beef that is reasonably lean but still has enough fat to cook comfortably in the skillet. The recipe does not need added oil. Break the meat into small crumbles as it cooks, and spoon off excess rendered fat so the finished sauce is rich without feeling greasy. Start with beef thawed in the refrigerator.

Regular dry spaghetti is a good fit for this sauce. Freshly grated cheddar and Monterey Jack melt smoothly, although packaged shredded cheese is convenient. Keep both canned tomato varieties: the plain diced tomatoes add body, while Rotel supplies the green chilies and a different layer of flavor.

Ingredients

• 12 ounces spaghetti
• 1 pound ground beef
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 (1-ounce) packet taco seasoning
• 1 (14.5-ounce) can of diced tomatoes, undrained
• 1 (10-ounce) can Rotel (diced tomatoes with green chilies)
• 1 cup beef or chicken broth
• 1 cup shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
• Fresh cilantro, chopped
• Sliced jalapeños
• Sour cream
• Diced avocado

Use both tomato cans with their juices. The broth and juices provide the sauce liquid, which reduces before the cooked pasta goes in. Because the seasoning packet, broth, and cheese already contain salt, taste a finished portion before adding any extra. Optional toppings are added at the table and are not needed to cook the dish.

How To Make Taco Spaghetti

Have the onion diced, garlic minced, and cheese measured before starting. Allow about 10 minutes to prepare and 30 minutes to cook. A wide, deep skillet gives the sauce room to simmer without splashing and leaves enough space to turn the spaghetti. Start heating the pasta water while you organize the remaining ingredients.

Step 1

Bring a large pot of water to a boil. Cook the spaghetti according to the package directions, stopping when it is just firm to the bite. Stir occasionally so the strands separate. Time it to finish while the sauce simmers, then drain without rinsing.

Step 2

Meanwhile, put the fully thawed ground beef and diced onion in a large, deep skillet over medium heat. Cook for about 7-9 minutes, breaking the beef into small pieces, until the onion softens and the beef reaches 160°F. Add the garlic and stir for about 30-60 seconds. Carefully spoon off excess fat into a heatproof container.

Step 3

Stir in the full packet of taco seasoning, the undrained diced tomatoes, the Rotel with its juices, and the cup of beef or chicken broth. Bring to a gentle simmer. Cook uncovered for about 8-10 minutes, stirring occasionally, until the sauce looks slightly thickened rather than watery.

Step 4

Add the drained spaghetti and toss gently with the sauce. Cook for another 2-3 minutes, turning the strands so the beef and tomatoes are distributed evenly. The sauce should cling to the pasta; avoid boiling hard or cooking until the pan is dry.

Step 5

Reduce the heat to low. Sprinkle all the cheddar and Monterey Jack cheese evenly over the top. Cover for about 2-3 minutes, just until the cheese melts. Remove from the heat once melted so the pasta does not stick underneath.

Step 6

Serve immediately in bowls. Add the optional cilantro, sliced jalapeños, sour cream, or diced avocado to individual portions. Keep any toppings intended for later refrigerated separately from the cooked spaghetti.

Notes

• Cook the pasta just until firm to the bite because it spends a few more minutes in the sauce. Very soft spaghetti can break when tossed.
• Stir the spaghetti during boiling rather than adding oil. Drain without rinsing so the surface starch can help the sauce cling.
• Keep the sauce uncovered while it reduces. A tightly covered skillet traps steam and leaves the tomato mixture thinner.
• Break the beef into fairly small crumbles. Large chunks tend to fall away from the long strands instead of mixing through.
• Use gentle heat once the cheese goes on. A strong simmer can dry the bottom of the pan before the top has melted.
• Choose the chili level before cooking. Mild tomatoes and mild taco seasoning are easier to build on with hot toppings later.
• Prepare avocado just before serving. Store other fresh toppings separately and add them after reheating any leftovers.

Ingredients You Can Add

• Black beans: Drain and rinse cooked canned beans, then warm them through in the sauce.
• Corn: Stir in cooked or thawed kernels for a little sweetness and texture.
• Bell pepper: Cook small diced pieces with the onion so they soften before the sauce finishes.
• Jalapeños: Offer fresh or pickled slices at the table so everyone can control the heat.
• Hot sauce: A small drizzle over a serving adds sharpness without changing the whole skillet.
• Tortilla chips: Crumble them over individual bowls at the last moment to keep their crunch.

What To Serve With Taco Spaghetti

My favorite way to serve Taco Spaghetti is with freshly chopped cilantro and a dollop of sour cream. A little avocado adds another cool, creamy bite. Keep these toppings in small bowls, then let everyone finish their own serving while the cheese is still soft.

Tortilla chips and On the Border Salsa make an easy side for a casual dinner. A green salad with a tangy dressing also balances the cheese. Since the main dish already includes pasta, a fresh vegetable side is usually enough to round out the meal.

Grilled Corn Salad is another colorful pairing, especially when you want something to prepare separately. If you enjoy this combination and want another pasta option for a future dinner, try Taco Pasta with its own ingredient list and cooking method.

Variations and Swaps

• Ground turkey: Replace the beef with ground turkey and cook it to 165°F before continuing with the sauce.
• Ground chicken: This also works, with the same 165°F minimum; very lean meat may need closer attention to prevent sticking.
• Cooked chicken: Use shredded cooked chicken and simmer it in the sauce until the whole mixture reaches 165°F.
• Vegetarian version: Use cooked beans or a suitable plant-based crumble and vegetable broth. Follow the crumble package instructions.
• Short pasta: Use the same listed pasta weight in a short shape and cook it according to its own package directions.
• Gluten-free version: Choose gluten-free pasta and check the broth, seasoning, and other packaged ingredients for suitability.
• Pepper Jack: Replace Monterey Jack with Pepper Jack for more heat while keeping the total cheese amount the same.
• Milder cheese: Use a mild cheddar if sharp cheddar tastes too strong. The tomato and taco-seasoning base still carries the main flavor.

Storage

Refrigerate leftovers in shallow covered containers within 2 hours of cooking, or 1 hour when temperatures are above 90°F. Keep the refrigerator at 40°F or below and use the pasta within 3 days. Store sour cream, avocado, cilantro, and other fresh toppings separately so they stay appealing.

Freeze individual cooked portions for up to 2 months for best quality. Thaw overnight in the refrigerator, then reheat gently on the stove or in the microwave until the center reaches 165°F. Stir or turn the pasta during reheating for even warmth. A small splash of broth can loosen sauce that has thickened in storage; add fresh toppings afterward.

FAQ

Can I cook the dry spaghetti directly in this sauce?

Keep the separate-pot method here. Cooking dry pasta in the skillet needs a different liquid balance and timing, so simply adding it to this measured sauce can leave the strands unevenly cooked.

Why is the sauce watery?

Both tomato cans and the broth add liquid. Simmer the sauce uncovered before adding the pasta, allowing extra time if needed. The cheese and spaghetti will give it more body afterward.

Why does the spaghetti stick together?

Stir it while boiling and time it to finish near the sauce. Leaving drained spaghetti sitting for a long time encourages clumping. Toss it gently into the warm sauce promptly.

Should I drain the Rotel?

No. Use the juices along with the undrained plain tomatoes. Reduce the sauce in the skillet instead of pouring away flavor from the cans.

Can I prepare the sauce ahead?

Yes. Refrigerate cooked sauce promptly, then reheat it to 165°F while cooking a fresh pot of spaghetti. Add the cheese once the hot pasta and sauce are combined.

What if my skillet is too small?

Use a wider, deeper pan from the start, or combine the cooked sauce and drained spaghetti in the empty pasta pot. Cover it over low heat just long enough to melt the cheese.
