Ingredients:
- 2 teaspoons olive oil
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 green bell pepper, diced
- 1 (15-ounce) can black beans, drained and rinsed
- 1 (10-ounce) can diced tomatoes with green chilies (such as Rotel)
- 1 (1-ounce) packet taco seasoning
- 12 ounces spaghetti, broken in half
- 3½ cups water
- 1 cup shredded cheddar cheese
- ½ cup sour cream
- Chopped green onions, for garnish
Directions:
- Sauté Aromatics: In a large pot or Dutch oven, heat olive oil over medium-high heat. Add diced onion, minced garlic, and diced green bell pepper. Sauté for 3-4 minutes until the vegetables are softened.
- Incorporate Beans and Seasoning: Add the drained black beans, diced tomatoes with their juices, and taco seasoning to the pot. Stir to combine, ensuring the spices evenly coat the vegetables and beans.
- Add Pasta and Liquid: Place the broken spaghetti into the pot, spreading it out as evenly as possible. Pour in 3½ cups of water, ensuring the pasta is submerged.
- Cook the Pasta: Bring the mixture to a boil. Cover the pot, reduce the heat to medium-low, and let it simmer for 10 minutes. After 10 minutes, uncover and stir thoroughly to prevent sticking. Continue to cook, uncovered, for an additional 5-8 minutes, stirring occasionally, until the spaghetti is cooked to your desired tenderness and most of the liquid has been absorbed.
- Incorporate Dairy: Once the pasta is cooked, turn off the heat. Stir in the shredded cheddar cheese and sour cream until both are fully melted and the mixture is creamy.
- Serve: Dish out the spaghetti into serving bowls and garnish with chopped green onions. Serve immediately.

Tips for the Best Taco Spaghetti
1. Use the Right Pasta
Regular spaghetti works well in this dish, but you can also try whole wheat pasta for extra fiber or gluten-free spaghetti if needed.
2. Don’t Skip the Cheese and Sour Cream
These ingredients bring a creamy, rich texture that ties the dish together. If you’re dairy-free, try using a plant-based cheese alternative and coconut yogurt.
3. Adjust the Spice Level
The diced tomatoes with chilies add a subtle heat, but if you like things spicier, toss in some red pepper flakes or extra cayenne. If you prefer a milder dish, use regular diced tomatoes instead.
4. Add Extra Veggies for More Nutrients
Bell peppers, corn, zucchini, or mushrooms would all blend seamlessly into this dish, adding more color and texture.
5. Make It a Meal Prep Favorite
This dish stores well in the fridge, making it great for leftovers. The flavors deepen overnight, making it even tastier the next day.
Delicious Ways to Customize Your Taco Spaghetti
This recipe is already packed with flavor, but if you love experimenting in the kitchen, here are a few variations you can try:
1. Make It Vegan
Swap out the cheese and sour cream for dairy-free alternatives like nutritional yeast and cashew cream.
2. Add Crunch with Tortilla Strips
Top each serving with crispy tortilla strips or crushed tortilla chips for added texture.
3. Try a Protein Boost
If you’re not strictly vegetarian, you can add cooked ground turkey, shredded chicken, or even crumbled tofu for extra protein.
4. Switch Up the Beans
Black beans are a great choice, but pinto beans, kidney beans, or even chickpeas would work just as well.
5. Play with the Cheese
Cheddar is classic, but you can also try pepper jack for extra spice, mozzarella for more creaminess, or cotija for a Mexican-style twist.
What to Serve with Taco Spaghetti
This dish is already a complete meal, but if you’re looking to round it out, here are some side dish ideas:
- Garlic Bread: A Tex-Mex take on spaghetti deserves a crispy, buttery slice of bread on the side.
- Side Salad: A simple avocado and lime-dressed salad balances the richness of the pasta.
- Guacamole: The cool creaminess of guac makes a great contrast to the warm, spicy spaghetti.
- Mexican Street Corn: Elote or esquites would pair beautifully with this dish.
