One-Pot Tex-Mex Chili Mac

Featured in: Weeknight Dinners

This hearty one-pot Tex-Mex classic combines the comfort of macaroni with the bold flavors of chili. Black beans, sweet corn, and diced tomatoes create a rich, flavorful base seasoned with chili powder, cumin, and smoked paprika. The dish cooks entirely in one pot—pasta simmers directly in the spiced broth, absorbing all those delicious southwestern flavors. A generous layer of shredded cheddar melts over the top, creating that irresistible golden, gooey finish. Optional garnishes like fresh cilantro, green onions, and jalapeños add bright contrasts. Perfect for feeding a family in under 40 minutes with minimal cleanup.

My sister texted me on a Tuesday asking what to make for dinner that would feed four people in under forty minutes, and I found myself describing this one-pot chili mac without even thinking twice. There's something about the way the cheese melts into those warm noodles and beans that just works, especially when you need something that tastes like comfort but doesn't demand hours at the stove. She made it that night and sent me a photo of her kids actually asking for seconds, which felt like winning the lottery in her house. That's when I realized this dish had quietly become the thing I reach for when life gets hectic and hunger is real.

I made this for a potluck last spring where everyone was supposed to bring something fancy, and I almost didn't go because I was bringing a one-pot chili mac. But something told me to go anyway, and watching people come back for thirds while ignoring the elaborate salads made me understand that sometimes the most honest food wins the room. A friend told me it reminded her of her grandmother's kitchen, which was the highest compliment I could have received.

Ingredients

  • Elbow macaroni, 2 cups uncooked: This shape cradles the chili and sauce beautifully, plus cooking it right in the pot means the pasta absorbs all those flavors instead of tasting plain.
  • Olive oil, 1 tablespoon: It's your foundation for building flavor, so don't skip it even though the amount seems small.
  • Yellow onion, 1 medium diced: This is where the sweetness comes from, so take your time dicing it evenly so it caramelizes just right.
  • Garlic, 2 cloves minced: Fresh garlic makes a noticeable difference here, and you'll smell it the moment it hits the hot oil.
  • Red bell pepper, 1 diced: Choose one that feels firm and bright, because it adds both color and a subtle sweetness that balances the spices.
  • Sweet corn, 1 cup frozen or canned drained: Frozen corn works beautifully and honestly tastes better than canned for this dish, but either works when you're in a pinch.
  • Black beans, 1 can rinsed and drained: Rinsing them removes excess sodium and prevents the pot from getting too thick and gluey.
  • Diced tomatoes with juice, 1 can: The juice is liquid gold here, so never drain it away no matter how tempting.
  • Vegetable or chicken broth, 2 cups: This is your control mechanism for the final texture, so use the full amount and don't be shy.
  • Chili powder, 2 tablespoons: This is the backbone of everything, so buy it from a store with good turnover so it's still vibrant and alive.
  • Ground cumin, 1 teaspoon: It adds warmth without making anything taste weird, trust me on this one.
  • Smoked paprika, 1 teaspoon: This gives you that slightly charred, campfire feeling even though you're cooking on your stovetop.
  • Dried oregano, ½ teaspoon: A little goes a long way, so measure carefully.
  • Salt, ½ teaspoon plus more to taste: Taste as you go because salt is personal and depends on your broth and beans.
  • Black pepper, ¼ teaspoon: Fresh cracked is lovely here if you have a grinder.
  • Cayenne pepper, ⅛ teaspoon optional: Only use this if heat is your love language, otherwise skip it completely.
  • Shredded cheddar or Mexican blend cheese, 1½ cups: Buy good cheese because it melts smoother and tastes miles better than the pre-shredded stuff with potato starch.
  • Green onions, fresh cilantro, jalapeños, sour cream for garnish: These are your finishing touches, the ones that make people feel special when they eat.

Warm the oil and build the base:
Heat your olive oil in a large heavy-bottomed pot over medium heat until it shimmers slightly. Add your diced onion and let it soften for 2 to 3 minutes, stirring every so often so nothing burns but everything gets a little golden.
Layer in the aromatics:
Stir in your garlic and red bell pepper, cooking for another 2 minutes until the garlic perfumes the whole kitchen. You'll know it's right when you can smell it clearly and your pepper is starting to soften at the edges.
Combine the vegetables and beans:
Add your corn, black beans, and tomatoes with all their juices, stirring everything together so nothing sticks to the bottom. This is where the dish starts to look like something real.
Bring it to a boil:
Pour in your broth and turn the heat up slightly until you see gentle bubbles breaking the surface. This takes maybe 3 to 4 minutes and signals you're ready for the next step.
Add pasta and spices:
Stir in your uncooked macaroni along with all your spices, making sure nothing clumps up and everything gets distributed evenly. The mixture will look a little loose, which is exactly what you want.
Simmer and let it meld:
Lower the heat to a gentle simmer, cover your pot, and cook for 10 to 12 minutes, stirring every couple of minutes so the pasta doesn't stick to itself or the bottom. The pasta will gradually soften and the liquid will reduce, which is the magic happening.
Melt the cheese blanket:
Remove the lid, sprinkle your cheese evenly over the entire surface, then cover again for 2 to 3 minutes. Peek after 2 minutes and you'll see it turning glossy and gooey, which is your signal that you're almost done.
Serve with joy:
Ladle into bowls while it's steaming hot and let people garnish their own way, with green onions or cilantro or jalapeños or a cool dollop of sour cream. This is when the dish becomes a conversation.

My neighbor knocked on my door one evening because the smell coming from my kitchen was making her curious, and we ended up eating this together on my porch while talking about nothing important and everything that mattered. There's something about a shared bowl that dissolves the usual walls between people, and this dish seems to do that more than anything else I cook.

Making It Your Own

This recipe is a canvas more than a prescription, and I've learned the hard way that the best version is always the one you customize without guilt. Add ground beef or turkey if you want protein beyond the beans, or use pinto beans instead of black ones if that's what's in your pantry. The spice blend is forgiving enough that you can dial it up or down depending on who's eating, and nobody will know you changed a thing.

Storage and Leftovers

This keeps beautifully in the refrigerator for three or four days in a covered container, and it actually tastes better the next day after everything has had time to get properly acquainted. Reheat it gently on the stovetop over low heat, adding a splash of broth if it's gotten thick, and it'll taste almost as good as the moment you made it. I've also frozen it successfully, though I usually eat it fresh because making it takes so little time that there's rarely any left.

When You're in a Hurry

I've made this with pre-diced vegetables from the grocery store and it still tastes wonderful, which tells you that the real magic is in the way the flavors come together rather than how you get there. The pasta cooks faster if you use smaller pieces or thinner pasta, and you can shave a few minutes off by having everything prepped before you turn on the heat. This is one of those recipes where taking shortcuts doesn't actually taste like you took shortcuts, which is the whole point.

  • Buy pre-diced onions and peppers if that means you'll actually make this instead of ordering takeout.
  • Set your timer for the pasta because the difference between al dente and mushy is about 2 minutes of attention.
  • Keep canned beans and tomatoes on your shelf always so this is truly a weeknight emergency option.

This dish has become my answer to so many questions, whether someone asks what to make or how to feed people without losing your mind. It's taught me that sometimes the most generous thing you can offer is food that's both simple and real, made without apology or pretense.

Recipe FAQs

Can I make this vegetarian or vegan?

Yes, use vegetable broth instead of chicken broth for a vegetarian version. For vegan, substitute plant-based cheese or omit the cheese entirely and top with avocado or extra vegetables.

What type of pasta works best?

Elbow macaroni is traditional, but small shells, cavatappi, or penne also work well. Choose pasta shapes that will cook evenly and hold the chunky sauce.

How can I add more protein?

Brown ground beef, turkey, or chicken with the onion at the start. You can also add extra beans or mix in some quinoa with the pasta for additional protein.

Can I make this ahead of time?

Yes, this reheats beautifully. Store in the refrigerator for up to 4 days. Add a splash of broth when reheating to restore creaminess, and fresh cheese topping before serving.

How do I adjust the spice level?

Start with less cayenne pepper or omit it entirely. Add chipotle powder, diced jalapeños, or hot sauce to individual servings so everyone can customize their heat preference.

What other beans can I use?

Pinto beans, kidney beans, or a mixed bean blend all work wonderfully. Each brings slightly different texture and flavor while maintaining the dish's hearty character.
