Tuesday evening, 5:47 PM. My 3-year-old was having a complete meltdown because her sock felt “too bumpy,” my husband was stuck in traffic, and I was staring at my empty meal plan like it might magically produce dinner ideas.
Then I spotted ground beef in the freezer and a box of spaghetti in the pantry, and something clicked. What if taco night crashed into pasta night? What if I could throw everything into one pan and call it a day?
Forty-five minutes later, my sock-sensitive toddler was asking for seconds, my husband was texting from the driveway asking what smelled so good, and I was feeling like the dinner hero I rarely feel like on weeknights.
This one-pot taco spaghetti bake has become my go-to when life gets messy and dinner needs to just work. Cheesy, spicy, satisfying, and dirty dish count: exactly one pan.
Perfect.

One-Pot Taco Spaghetti Bake Recipe
This recipe serves about 6 people generously, though in my house it sometimes disappears faster than expected. Here’s what you’ll need:
Ingredients
| Ingredient | Amount |
| Ground beef (80/20 works great) | 1 lb |
| Taco seasoning | 4 tbsp |
| Yellow onion, diced | ½ small |
| Olive oil | 2 tbsp |
| Rotel tomatoes, undrained | 10 oz can |
| Water | 3 cups |
| Spaghetti noodles, uncooked | 8 oz |
| Sharp cheddar cheese, shredded | ⅔ cup |
| Fresh cilantro, chopped | ⅓ cup |
Tools You’ll Need
- Large oven-safe skillet (cast iron works beautifully)
- Wooden spoon or spatula
- Sharp knife and cutting board
- Measuring cups and spoons
- Oven mitts
Optional Add-ons for Extra Flavor
- Diced bell peppers for crunch and color
- Black beans for extra protein
- Corn kernels for sweetness
- Jalapeños for heat lovers
- Sour cream and avocado for serving
Step-by-Step Instructions
Step 1: Prep Your Oven and Ingredients
Preheat your oven to 350°F. While it’s heating, dice your onion into small pieces and get all your other ingredients within reach. Trust me, once you start cooking, things move quickly.
Step 2: Brown the Beef
Heat the olive oil in your large oven-safe skillet over medium-high heat. Add the ground beef and break it up with your spoon as it cooks.
Cook for about 5-7 minutes until it’s mostly browned with just a few pink spots remaining. If there’s a lot of grease pooling, drain off the excess, but leave a little for flavor.
Step 3: Add the Aromatics
Toss in your diced onion and cook for another 2-3 minutes until it starts to soften and smell amazing. The onion should be translucent and the beef should be completely browned by now.
Step 4: Season Everything
Sprinkle the taco seasoning over the beef and onions, stirring well to coat everything evenly. Cook for about 30 seconds until fragrant.
This is where your kitchen starts smelling like a taco shop, and everyone mysteriously appears asking what’s for dinner.
Step 5: Add the Liquid Base
Pour in the entire can of Rotel tomatoes, juice and all. This is crucial – don’t drain them! That liquid helps cook the pasta and adds flavor.
Add the 3 cups of water and stir everything together. It will look soupy, but don’t panic. The pasta will absorb most of this liquid as it cooks.
Step 6: Add the Pasta
Break the spaghetti noodles in half (makes them easier to manage) and add them to the skillet. Use your spoon to push them down so they’re mostly submerged in the liquid.
Bring everything to a boil, then reduce heat to medium-low, cover, and simmer for 10-12 minutes. Stir every few minutes to prevent sticking.
The pasta should be al dente and most of the liquid should be absorbed when it’s ready.
Step 7: Top and Bake
Remove the lid and sprinkle the shredded cheddar evenly over the top. Don’t be stingy here – the cheese creates a beautiful golden top that everyone fights over.
Transfer the skillet to your preheated oven and bake for 15-20 minutes until the cheese is melted, bubbly, and golden brown in spots.
Step 8: Finish and Serve
Remove from the oven (careful, that handle is HOT!) and sprinkle the fresh cilantro over the top. Let it rest for about 5 minutes to set up, then serve directly from the skillet.
The first bite should give you perfectly cooked pasta, melted cheese, and all those taco flavors in one amazing forkful.
Storage and Reheating
Leftovers keep beautifully in the fridge for up to 4 days. I usually transfer them to a regular container since storing the cast iron skillet in the fridge isn’t practical.
To reheat, microwave individual portions for about 90 seconds, stirring halfway through. For larger portions, reheat in a 350°F oven for about 15 minutes until warmed through.
You can also freeze this for up to 2 months. Thaw overnight in the fridge before reheating.
Substitutions and Variations
Ground turkey instead of beef – Works great for a lighter option, though you might need to add a bit more seasoning.
Different cheeses – Mozzarella gives you more stretch, pepper jack adds heat, or try a Mexican cheese blend for authentic vibes.
Fire-roasted Rotel – Adds a subtle smoky flavor that takes this to the next level.
Vegetarian version – Use plant-based ground “meat” or extra beans and vegetables.
Spice level adjustments – Use mild Rotel and reduce taco seasoning to 3 tablespoons for sensitive palates, or add diced jalapeños and hot sauce for heat lovers.

Perfect Pairings
This dish is pretty complete on its own, but here are some sides that complement it beautifully:

- Mexican street corn if you’re going full theme night
- Cold beer or margaritas for the grown-ups
Common Mistakes and How to Avoid Them
I’ve made this recipe probably 30 times, and I’ve learned from every mistake. Here’s how to avoid the most common pitfalls:
Adding too much water. Stick to exactly 3 cups. More water means soupy pasta that never quite comes together. I learned this the hard way when I “eyeballed” it once.
Not stirring the pasta enough. Those noodles will stick together and to the bottom of the pan if you don’t stir every few minutes. Set a timer to remind yourself.
Draining the Rotel. That juice is liquid gold! It adds flavor and helps cook the pasta. Keep every drop in there.
Frequently Asked Questions
Can I use fresh tomatoes instead of Rotel?
You can, but you’ll need to dice about 1 cup of tomatoes and add an extra ¼ cup of water. You’ll also lose some of that signature Rotel flavor.
What if I don’t have taco seasoning?
Make your own by mixing 1 tablespoon chili powder, 1 teaspoon each of cumin and paprika, ½ teaspoon each of onion powder and garlic powder, and ¼ teaspoon cayenne.
Is this too spicy for kids?
It has a mild kick but isn’t truly spicy. If you have very sensitive eaters, use mild Rotel and reduce the taco seasoning slightly.
Can I make this ahead of time?
You can prep it through step 6, then refrigerate for up to a day before adding cheese and baking. Add about 5 extra minutes to the baking time if starting from cold.
