Ingredients
- 1 lb ground beef
- 1 small yellow onion, diced
- 2 cloves garlic, minced
- 1 packet (1 oz) taco seasoning
- 1 can (10 oz) diced tomatoes with green chilies (like Ro-Tel), undrained
- 3 cups water
- 8 oz uncooked spaghetti, broken in half
- 1 cup shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- Salt and pepper, to taste
- Fresh cilantro, chopped (optional garnish)
Ingredient Swaps & Tips
- Ground Beef: Swap with ground turkey or plant-based crumbles.
- Cheese: Use a Mexican blend, Monterey Jack, or even Velveeta for extra creaminess.
- Pasta: Penne or rotini work great too—just adjust cooking time slightly.
- Add Heat: Stir in a diced jalapeño or a splash of hot sauce.
- Boost Fiber: Add black beans or corn to bulk it up!
How to Make One-Pot Cheesy Taco Spaghetti
1. Brown the Beef
In a large skillet or Dutch oven over medium heat, cook the ground beef and diced onion for 5–7 minutes until browned and soft. Add garlic and sauté 1 minute more. Drain excess grease.
2. Add Taco Flavor
Stir in taco seasoning until meat is coated. Add the full can of diced tomatoes with green chilies (juice and all). Stir well.
3. Cook the Pasta
Add 3 cups water and bring to a boil. Add broken spaghetti, reduce heat to low, and simmer covered for 12–15 minutes, stirring occasionally. Pasta should be tender and most liquid absorbed.
4. Get Cheesy
Remove from heat. Stir in half the shredded cheddar and mozzarella until melted and creamy. Sprinkle remaining cheese over the top, cover, and let sit for 2–3 minutes until melty.
5. Finish & Serve
Taste and adjust salt and pepper. Garnish with chopped fresh cilantro, if desired.
Pro Tips for Success
- Stir frequently so pasta doesn’t stick to the bottom.
- Use pre-shredded cheese for speed, or grate your own for extra melt factor.
- If sauce gets too thick, add a splash of milk or broth.
- Leftovers reheat beautifully the next day—just add a splash of water and microwave.
