Ingredient List

For the pasta

• 12 oz elbow macaroni (or small pasta of choice)
• 1 tbsp olive oil

For the chili base

• 1 lb ground beef
• 1 small onion, finely chopped
• 2–3 cloves garlic, minced
• 1 can (14 oz) diced tomatoes
• 1 can (8 oz) tomato sauce
• 1 cup beef broth
• 1 tbsp tomato paste

Seasonings

• 2 tsp chili powder
• 1 tsp smoked paprika
• 1 tsp cumin
• ½ tsp dried oregano
• ½ tsp salt (or to taste)
• ¼ tsp black pepper
• Pinch of cayenne pepper (optional, for extra heat)

For the cheese sauce

• 2 cups shredded cheddar cheese
• ½ cup mozzarella cheese (optional, for extra meltiness)
• ½ cup milk or heavy cream

Ingredient Notes

• Elbow macaroni works best for that classic chili mac and cheese feel, but shells or rotini also hold the sauce really well.
• I always use sharp cheddar cheese because it gives that bold, slightly tangy flavor that makes the dish taste richer and more satisfying.
• Don’t skip the tomato paste—it deepens the flavor and gives the chili base that slow-cooked taste even though everything is made in one pot.
• Smoked paprika is a game changer here. It adds a subtle smoky warmth that takes this from basic to seriously flavorful.
• Use beef broth instead of water if you can—it makes the sauce so much more savory and ties everything together beautifully.
• Add the cayenne only if you like heat. Even a small pinch can turn this into a proper spicy mac and cheese without overpowering the cheese.

Kitchen Equipment Needed

• Large deep pot or Dutch oven – This is where everything comes together. I love using a heavy-bottomed pot because it prevents sticking and helps the sauce cook evenly.
• Wooden spoon or silicone spatula – Perfect for stirring the pasta as it cooks and keeping everything from clumping or sticking to the bottom.
• Sharp knife – For chopping onions and garlic quickly and cleanly without slowing you down.
• Cutting board – Keeps your prep organized and makes cleanup easier. I usually keep a separate one just for veggies when I’m cooking this.
• Measuring cups and spoons – Helps keep the spice and liquid ratios balanced so the chili mac and cheese turns out consistent every time.
• Cheese grater – Freshly shredded cheese melts better and gives the sauce that smooth, creamy finish I always look for in this dish.

Instructions

Step 1: Brown the beef and build the flavor base

• Start by heating a large deep pot or Dutch oven over medium heat. Add the olive oil, then toss in the ground beef.
• Break the beef apart as it cooks so it browns evenly. You want it fully cooked with no pink left, and a little bit of browning at the bottom of the pot for extra flavor.
• Once the beef is browned, add the chopped onions and cook for about 3–4 minutes until they soften. Stir in the minced garlic and cook for another 30 seconds until fragrant.

Pro tip: Don’t rush the browning step—it’s where a lot of the deep flavor for your chili mac and cheese starts.

Step 2: Add the tomatoes, broth, and seasonings

• Pour in the diced tomatoes, tomato sauce, beef broth, and tomato paste. Stir everything together until well combined.
• Add the chili powder, smoked paprika, cumin, oregano, salt, black pepper, and cayenne (if using). Mix well so the spices are evenly distributed.
• Bring the mixture to a gentle simmer so all those flavors can start blending together.

Pro tip: Let the mixture simmer for a couple of minutes before adding pasta—this helps the spices bloom and deepen the taste.

Step 3: Cook the pasta in the same pot

• Add the uncooked macaroni directly into the pot. Stir well so the pasta is fully submerged in the liquid.
• Lower the heat slightly and let it simmer uncovered, stirring occasionally to prevent sticking. Cook until the pasta is tender and most of the liquid has been absorbed, about 10–12 minutes.
• If it starts looking too thick before the pasta is fully cooked, add a splash of water or broth.

Pro tip: Stir more frequently toward the end so the pasta doesn’t stick to the bottom of the pot.

Step 4: Make it creamy and cheesy

• Once the pasta is cooked, reduce the heat to low. Pour in the milk or cream and stir gently to create a smooth, creamy base.
• Add the shredded cheddar cheese and mozzarella (if using) a little at a time, stirring continuously until fully melted and silky.
• Let it sit for 1–2 minutes so the sauce thickens slightly.

Pro tip: Add cheese gradually and keep stirring—this is what gives your spicy mac and cheese that ultra-creamy texture without clumps.

Step 5: Taste and serve

• Give your chili mac and cheese a final taste and adjust seasoning if needed. Add a pinch more salt or chili powder if you want more kick.
• Serve warm straight from the pot for the best texture and flavor.

Pro tip: Let it rest for 5 minutes before serving—it thickens slightly and the flavors settle beautifully.

Tips and Tricks for Success

• Stir often while the pasta cooks: This keeps the macaroni from sticking to the bottom and ensures even cooking throughout the pot.
• Don’t overcook the pasta: Take it off the heat when it’s just tender—remember it will continue to soften slightly in the hot sauce.
• Shred your own cheese if possible: Pre-shredded cheese can be convenient, but freshly grated melts smoother and gives a creamier finish.
• Adjust the thickness at the end: If your chili mac and cheese feels too thick, add a splash of broth or milk. If it’s too loose, let it sit uncovered for a few minutes.
• Taste before serving: The spices can mellow as it cooks, so a final seasoning check helps you get the perfect flavor balance.

Ingredient Substitutions and Variations

• Ground turkey or chicken instead of beef: A lighter option that still works well with the chili spices and cheese sauce.
• Vegetarian version: Swap the meat for black beans, lentils, or a mix of both for a hearty meat-free meal.
• Different pasta shapes: Elbows are classic, but shells, penne, or rotini all hold the sauce beautifully.
• Cheese variations: Try pepper jack for extra spice, or a mix of cheddar and gouda for a richer, smoky flavor.
• Extra veggies: Add bell peppers, corn, or even zucchini for more texture and nutrition without changing the comfort-food vibe.
• Make it extra spicy: Increase cayenne pepper or add chopped jalapeños for a real kick in your spicy mac and cheese.

Serving Suggestions

• I love serving this chili mac and cheese with warm garlic bread—it’s perfect for scooping up every bit of that creamy, cheesy sauce.
• A crisp green salad on the side balances the richness really well, especially something with a light vinaigrette.
• It pairs beautifully with roasted vegetables like broccoli, carrots, or zucchini for a more filling and wholesome meal.
• Sometimes I top it with extra shredded cheese and a sprinkle of chopped parsley right before serving for a fresh finish.
• For a cozy night in, I enjoy it on its own in a big bowl with a little extra chili flakes on top for added heat.

Storage and Reheating Instructions

• Refrigeration: Store leftovers in an airtight container and keep in the fridge for up to 3–4 days.
• Freezing: You can freeze it for up to 2 months, but the texture may be slightly softer once thawed due to the pasta and cheese sauce.
• Reheating on the stove: Warm over low heat with a splash of milk or broth, stirring often until creamy again.
• Microwave method: Heat in short intervals, stirring between each round and adding a little liquid if it looks too thick.
• Tip for best texture: Always reheat gently—high heat can cause the cheese sauce to separate.
