Featured in: Weeknight Dinners

This one-pot Tex-Mex inspired pasta brings together tender macaroni, black beans, corn, and bold spices in a single skillet. The macaroni cooks directly in the vegetable broth, absorbing all the smoky, savory flavors while creating a thick, satisfying sauce. After just 45 minutes, you'll have six servings topped with melted cheddar cheese and fresh cilantro. It's perfect for busy weeknights when you want something hearty and filling without the cleanup.

My neighbor dropped by on a random Tuesday evening with a bag of corn from her garden, and I had maybe thirty minutes to throw together something that wouldn't feel like leftovers pretending to be dinner. I found a can of black beans in the back of my cabinet, some pasta, and a block of cheddar, and it hit me—why not just throw it all in one pot and let the flavors do the work? That first bite, with the cheese melting into the warm chili-spiced pasta, felt like I'd accidentally discovered something people actually wanted to eat.

I made this for my kids' soccer team parents at a casual potluck, honestly not sure how it would land, and watched people go back for seconds without asking what was in it. One parent asked for the recipe right there while eating, which felt like the highest compliment I could get—not because it was fancy, but because it tasted like comfort and generosity in a bowl.

Ingredients

  • Elbow macaroni (340 g / 12 oz): The small shape holds onto the broth and spices beautifully, and it softens just enough in the simmering liquid without turning mushy if you watch the timing.
  • Black beans (1 can, drained and rinsed): They add protein and earthiness, and rinsing them removes extra sodium so you control the salt level.
  • Medium onion: Diced and cooked first, it becomes sweet and creates the base layer of flavor that everything else builds on.
  • Garlic (2 cloves, minced): Don't skip mincing it finely—it distributes better and won't leave harsh chunks.
  • Red bell pepper: Adds brightness and sweetness that balances the spice, plus a bit of texture that stays present even after cooking.
  • Diced tomatoes (1 can, 400 g / 14 oz): The acidity keeps everything tasting fresh and prevents the dish from feeling too heavy.
  • Frozen or canned corn (1 cup / 150 g, drained): It brings natural sweetness and a hint of texture—frozen is fine and sometimes even better than fresh for consistent flavor.
  • Tomato paste (2 tablespoons): This is your secret weapon; it concentrates tomato flavor and adds depth that canned tomatoes alone can't deliver.
  • Jalapeño (1, optional): Seeding it removes most of the heat while keeping that subtle warmth and flavor; taste as you go if you're unsure.
  • Vegetable broth (3 cups / 720 ml): The liquid that becomes your sauce, so don't use anything too salty or it'll overpower the spices.
  • Olive oil (1 tablespoon): Just enough to soften the vegetables without making the finished dish greasy.
  • Chili powder (2 teaspoons): The backbone spice—this is what makes it taste Tex-Mex rather than generic.
  • Ground cumin (1 teaspoon): It adds warmth and earthiness that ties all the flavors together.
  • Smoked paprika (1 teaspoon): This gives you a subtle smoky note without needing actual smoke, which is honestly genius.
  • Dried oregano (1 teaspoon): Herbaceous and slightly peppery, it rounds out the spice blend.
  • Salt and black pepper: Start with what's called for, but taste and adjust—canned ingredients vary in saltiness.
  • Shredded cheddar cheese (1½ cups / 150 g): Melted on top, it becomes creamy and ties everything together; Mexican blend works too if you want more flavor complexity.
  • Fresh cilantro (2 tablespoons, chopped): The final garnish that makes it taste bright and finishes it like you meant to be fancy.

Start with the base:
Heat olive oil in your large pot over medium heat, then add the diced onion and let it cook for 3 to 4 minutes until it softens and turns translucent at the edges. You'll smell it before you see the change, and that's your signal that it's ready for the next step.
Build the aromatic layer:
Add the minced garlic, red bell pepper, and jalapeño if you're using it, and sauté everything together for about 2 minutes. The garlic will perfume your whole kitchen, which is always a good sign.
Awaken the spices:
Sprinkle in all the dry spices—chili powder, cumin, paprika, oregano, salt, and pepper—and stir constantly for just 1 minute. This short cooking time releases the essential oils in the spices and prevents them from burning while distributing the flavors evenly.
Deepen the flavor base:
Stir in the tomato paste and let it cook with the spices for a few seconds before adding everything else. This small step caramelizes the paste slightly and concentrates its flavor in a way that makes a real difference.
Combine all the wet ingredients:
Add the diced tomatoes, corn, black beans, and vegetable broth, stirring well so nothing sticks to the bottom. The mixture should look soupy at this point, which is exactly right.
Bring it to life:
Turn the heat up until you see a gentle boil, then add the macaroni and reduce the heat to a simmer. Cover the pot and let it cook for 10 to 12 minutes, stirring occasionally, until the pasta is tender and the liquid has mostly absorbed—this is the magic moment when one-pot cooking really shows its power.
Finish with cheese:
Once the pasta is cooked, uncover the pot, give everything a good stir, and sprinkle the shredded cheese evenly over the top. Cover it again and let it sit off heat for 2 to 3 minutes so the cheese melts into creamy ribbons throughout.
Serve and celebrate:
Divide into bowls and top with fresh cilantro, green onions, sour cream, or tortilla chips—whatever sounds right in the moment. Serve it hot while the cheese is still soft and the flavors are singing.

There's something about watching someone taste this for the first time and immediately understand why it's become a regular in my rotation—it's not pretentious or complicated, it's just honest and warm. That's when I knew it wasn't just a one-pot dinner; it was the kind of thing people remember eating at your table.

Why This Works as a Crowd-Pleaser

This dish sits right in that sweet spot where it tastes thoughtfully seasoned without being intimidating, and there's something about Tex-Mex flavors that just makes people happy. The sweetness from the corn and the slight heat from the chili powder create a balance that doesn't require a culinary degree to appreciate, just genuine ingredients and a little patience while everything simmers together.

Adaptations That Keep It Fresh

The beauty of this recipe is that it invites improvisation without falling apart—I've made it with ground turkey crumbled in, I've added sliced jalapeños for more heat, I've even used leftover roasted vegetables when I needed to clear the fridge. The structure is forgiving enough that as long as you keep the ratio of pasta to liquid roughly consistent, you can make it yours without second-guessing yourself.

Storage and Make-Ahead Magic

Leftovers actually improve overnight as the flavors meld and deepen, making this perfect for meal prep or when you know you'll be too tired to cook the next day. The cheese keeps everything creamy in the fridge for up to 3 days, though I'd reheat it gently in a pot with a splash of broth rather than the microwave if you want it to taste like fresh.

  • Make it vegan by swapping in plant-based cheese or leaving the cheese off entirely and adding an extra cup of diced tomatoes for creaminess.
  • For a heartier meat version, brown some ground beef or turkey and stir it in after sautéing the vegetables.
  • Freeze portions in airtight containers for up to a month, and thaw overnight in the fridge before reheating gently on the stovetop.

This recipe taught me that sometimes the best meals are the ones that don't demand your constant attention or a long ingredient list, but instead let simple things work together naturally. Make it once, and it'll probably become one of those dishes you turn to when you want to feel like you've cooked something worthwhile in under an hour.

Recipe FAQs

Can I make this gluten-free?

Yes, simply substitute the regular elbow macaroni with your favorite gluten-free pasta. The cooking time may vary slightly, so check the package instructions and adjust accordingly. All other ingredients are naturally gluten-free.

How spicy is this dish?

The spice level is mild to medium, coming from the chili powder, cumin, and optional jalapeño. You can easily adjust the heat by reducing or increasing the amount of chili powder and jalapeño to suit your family's preferences.

Can I add meat to this?

Absolutely. Brown 1 pound of ground beef or turkey with the onion in step 1 before adding the spices. This will increase the yield and add extra protein. Drain any excess fat before proceeding with the remaining ingredients.

How should I store leftovers?

Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of water or broth to restore the creamy texture. The pasta will continue to absorb liquid, so you may need to add more moisture when reheating.

What cheese works best for the topping?

Sharp cheddar provides the best flavor contrast, but a Mexican cheese blend, pepper jack for extra heat, or Colby jack all work wonderfully. For a dairy-free version, use your favorite plant-based shredded cheese or simply omit it altogether.
