Step-by-Step Instructions: How to Make Chili Mac and Cheese

This recipe is designed to be approachable yet deeply flavorful. It strikes a balance between the quick convenience of a one-pot meal and the depth of flavor you’d expect from a slow-simmered chili or rich baked mac and cheese. Let’s walk through each step in detail.

Ingredients You’ll Need

For the Chili Base:

• 1 tablespoon olive oil (or neutral oil like vegetable or canola)

• 1 medium yellow onion, finely chopped

• 1 green bell pepper, diced

• 2–3 garlic cloves, minced

• 1 lb (450g) ground beef (or turkey, pork, or plant-based alternative)

• 1 tablespoon tomato paste

• 1 teaspoon ground cumin

• 1 teaspoon smoked paprika

• 2 teaspoons chili powder (adjust to spice preference)

• ½ teaspoon dried oregano

• Salt and pepper, to taste

• 1 (15 oz) can diced tomatoes (with juices)

• 1 (15 oz) can kidney beans or black beans, drained and rinsed

• 1½ cups beef or chicken broth (or vegetable broth)

For the Mac and Cheese Portion:

• 2 cups elbow macaroni (uncooked)

• 1½ cups whole milk (or half-and-half for richer flavor)

• 2 tablespoons unsalted butter

• 2 tablespoons all-purpose flour

• 2 cups sharp cheddar cheese, shredded (plus more for topping)

• ½ cup mozzarella or Monterey Jack cheese, shredded

• 1 teaspoon Dijon mustard (optional, enhances cheese flavor)

• Salt to taste

Instructions

Step 1: Build Your Flavor Base with Aromatics

Heat 1 tablespoon of olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat. Once the oil is shimmering (but not smoking), add your chopped onion and diced green bell pepper.

Why this matters: Sautéing the aromatics first brings out their sweetness and depth. Onions and peppers form the aromatic foundation of countless comfort food recipes, and their flavor becomes more complex when slowly cooked until soft and translucent.

Cook for about 5–6 minutes, stirring occasionally, until the onions become translucent and the peppers begin to soften.

Add the minced garlic and cook for another 30–60 seconds, just until fragrant. Don’t let the garlic brown, or it will become bitter.

Step 2: Brown the Ground Meat

Add the ground beef (or your meat of choice) directly into the pot with the sautéed vegetables. Use a wooden spoon or spatula to break the meat into small pieces as it cooks.

Cook until fully browned, about 6–8 minutes, making sure no pink remains. If your meat releases a lot of fat, you may drain some off — but don’t discard all of it. A little bit of fat equals flavor.

Optional Tip: For extra depth, let the meat brown without stirring for the first minute or two. This encourages caramelization (the Maillard reaction) for a richer, meatier taste.

Step 3: Add Tomato Paste and Spices

Once the meat is browned, stir in 1 tablespoon of tomato paste. Cook it for 2–3 minutes, letting it “toast” in the pot. This removes the raw, metallic taste and brings out its natural sweetness and umami.

Next, add your spice mix:

• 1 teaspoon ground cumin

• 1 teaspoon smoked paprika

• 2 teaspoons chili powder

• ½ teaspoon oregano

• Salt and pepper to taste (start with ½ teaspoon of salt and adjust later)

Stir well to coat the meat and vegetables evenly.

Why toast the spices? Toasting spices in the oil and tomato paste “blooms” their flavor, making your chili taste like it simmered for hours — even though it hasn’t.

Step 4: Add Tomatoes, Beans, and Broth

Pour in the diced tomatoes (with their juices), the drained beans, and your broth of choice (beef, chicken, or vegetable).

Stir everything together to combine into a rich, hearty chili mixture.

Bring the mixture to a gentle boil, then reduce the heat to a simmer.

Cover and simmer for 15–20 minutes, stirring occasionally.

Why this step matters: This allows the flavors to meld and the spices to mellow. Simmering thickens the chili and infuses every bite with flavor. It also gives you time to prepare the pasta and cheese sauce in the next steps.

Step 5: Cook the Pasta Separately (or Not)

You have two choices here:

• Option A (One-Pot Method): Add the uncooked elbow macaroni directly into the simmering chili. Stir well, cover, and cook for 10–12 minutes, or until pasta is tender. Stir occasionally and keep an eye on the liquid level—add more broth or water if needed.

• Option B (Separate Boil Method): In a separate pot, bring salted water to a boil and cook the elbow macaroni until just al dente (usually 1 minute less than package instructions). Drain and set aside.

Why consider both?
Cooking the pasta in the chili saves time and cleanup. However, boiling it separately gives you more control over the texture and avoids over-thickening the chili if you’re not careful with liquid levels.

Step 6: Make the Cheese Sauce (Optional but Recommended)

In a small saucepan over medium heat, melt 2 tablespoons of butter. Once melted and bubbling, whisk in 2 tablespoons of all-purpose flour to create a roux.

Cook the roux for 1–2 minutes, stirring constantly, until it turns a light golden color.

Slowly whisk in the milk (1½ cups), making sure there are no lumps.

Cook the mixture, whisking frequently, until it thickens — about 4–5 minutes.

Remove from heat and stir in the shredded cheeses and optional Dijon mustard. Stir until fully melted and smooth.

Why make a separate cheese sauce?
It creates a creamier, smoother cheese flavor compared to simply adding cheese into a hot chili base. The roux stabilizes the sauce and prevents graininess.

Step 7: Combine Chili, Pasta, and Cheese Sauce

If you cooked your pasta separately, now is the time to fold it into the chili base.

Next, pour in your cheese sauce and stir gently to combine everything into a luscious, rich Chili Mac and Cheese.

Taste and adjust for seasoning — more salt, a pinch of cayenne, or even a splash of hot sauce if desired.

Step 8: Add Cheese Topping and Melt (Optional)

If you want a cheesy crust, sprinkle more shredded cheddar or a blend of cheeses over the top of the mixture.

Place the pot under a broiler for 2–3 minutes (oven-safe cookware only), or bake at 375°F (190°C) for 10–15 minutes until the top is bubbly and golden.

Step 9: Rest and Serve

Remove from heat and let the Chili Mac rest for 5 minutes before serving. This helps the flavors settle and thickens the consistency slightly.

Serve hot in bowls, optionally topped with:

• Fresh chopped parsley or cilantro

• A dollop of sour cream

• Sliced green onions

• Crushed tortilla chips

• Pickled jalapeños for heat
