Preparation Phase & Tools to Use

To make a seamless one-pot meal like this, choosing the right tools makes a big difference:

Large Heavy-Bottom Pot or Dutch Oven: Essential for even heat distribution and preventing scorching. It’s the backbone of this recipe—your one pot for everything.
Wooden Spoon or Silicone Spatula: For stirring without scratching your pot and getting into all the corners as the chili thickens.
Cheese Grater: Freshly grated cheese melts better and gives a creamier texture. Skip the pre-shredded for best results.
Ladle or Large Spoon for Serving: Makes it easier to scoop up hearty portions of pasta, meat, and beans.
Sharp Knife & Cutting Board: For prepping your onions, garlic, and any add-ins like bell peppers or jalapeños.

Having these on hand will make the cooking process smoother, cleaner, and more enjoyable.

Ingredients for the One Pot Chili Mac and Cheese

Kidney Beans: Adds creaminess and a traditional chili vibe while boosting the fiber content.
Diced Tomatoes (with juices): Brightens up the dish and provides moisture and acidity.

Onion & Garlic: The aromatic backbone—they deepen the flavor from the very first sauté.
Chili Powder & Cumin: These spices give the dish its signature chili warmth.
Paprika & Oregano: Layers in smoky and herbaceous undertones.
Beef Broth: Helps cook the pasta and adds a savory, well-rounded depth.
Shredded Cheddar Cheese: Melts beautifully into the dish for creaminess and comfort.

How To Make the One Pot Chili Mac and Cheese

Step 1: Sauté the Aromatics

Heat a tablespoon of oil in a large pot over medium heat. Add chopped onions and cook until translucent, about 3-4 minutes. Stir in minced garlic and cook for another 30 seconds until fragrant.

Step 2: Brown the Beef

Add the ground beef and cook, breaking it up with your spoon until it’s no longer pink. Drain excess grease if needed.

Step 3: Build the Chili Base

Stir in tomato paste, chili powder, cumin, paprika, oregano, salt, and pepper. Cook for 1-2 minutes to toast the spices. Then add diced tomatoes (with juices), drained kidney beans, and beef broth. Bring everything to a simmer.

Step 4: Add the Pasta

Once the mixture is simmering, add the elbow macaroni. Stir well and reduce heat to maintain a gentle simmer. Cover and cook for 10-12 minutes, stirring occasionally, until pasta is tender.

Step 5: Melt in the Cheese

Turn off the heat. Stir in freshly grated cheddar cheese until fully melted and creamy. Taste and adjust seasoning as needed.

Step 6: Garnish and Serve

Top with extra cheese, chopped cilantro, or sliced jalapeños if desired. Serve hot and enjoy!

Serving and Storing This One Pot Chili Mac and Cheese

Serve this chili mac hot and melty, straight from the pot. It’s perfect for family dinners, casual gatherings, or cozy nights in. A side of crusty bread or a crisp green salad complements the rich and hearty flavors beautifully.

If you have leftovers, this dish stores exceptionally well. Let it cool completely, then transfer to an airtight container and refrigerate for up to 4 days. For longer storage, freeze individual portions for up to 2 months. Reheat gently on the stovetop or in the microwave with a splash of broth or water to loosen it up and restore the creamy texture.

Frequently Asked Questions

What kind of pasta works best for chili mac?

Elbow macaroni is traditional and holds up well, but you can substitute with small shells or rotini if that’s what you have on hand.

Can I make this vegetarian?

Yes! Skip the ground beef and use plant-based meat alternatives or add extra beans like black beans or pinto beans. Use vegetable broth instead of beef broth.

Is it spicy?

It has a mild warmth from the chili powder and optional jalapeños. Adjust spice levels to taste by increasing or reducing chili powder, or adding hot sauce at the end.

Can I make this ahead of time?

Definitely. Make it up to 2 days ahead, refrigerate, and reheat with a bit of broth. The flavors actually get deeper and better over time.

What cheese melts best for this dish?

Sharp cheddar is classic, but Monterey Jack, Pepper Jack, or a mix of both also melt beautifully and add depth.

How can I make it creamier?

For an extra luscious texture, stir in a spoonful of sour cream or a splash of heavy cream before serving.
