Chili Mac in a bowl

Chili mac is a nostalgic, Midwestern-inspired dish that combines two beloved classics into one satisfying casserole. There are two common approaches: stir macaroni directly into a pot of chili, or mix prepared chili with mac and cheese and bake it until bubbly and golden. This recipe follows the latter method: fresh homemade mac and cheese combined with a robust beef chili, then baked to meld flavors and textures.

What You Need for Chili Mac

At its core, chili mac requires two elements: a flavorful chili and a creamy macaroni-and-cheese. For best results, make both components fresh on the same day. Use your favorite mac and cheese base and chili — whether that’s a classic beef chili, a turkey version, or a vegetarian chili — then mix and bake.

Recommended pairings include a classic homemade mac and cheese and a hearty beef chili, but you can substitute with vegetarian, vegan, or gluten-free versions to fit dietary needs. Aim for roughly equal volumes of each so the casserole holds together and bakes evenly.

Mac and Cheese Ideas

  • Classic creamy mac and cheese (regular or reduced-fat)
  • Instant Pot mac and cheese with added protein options
  • Vegan cheese sauce-based mac for a dairy-free option

Chili Ideas

  • Classic beef chili with tomatoes and beans
  • Vegetarian chili with beans and roasted vegetables
  • Lean turkey or chicken chili for a lighter option
  • Quinoa chili for extra plant-based protein

Chili Mac Variations

Extra vegetables: Stir in diced bell pepper, a cup of corn, or some sautéed mushrooms before baking for added texture and nutrition.

Vegetarian: Replace ground beef with kidney beans and use vegetable broth in your chili base.

Vegan: Use a dairy-free cheese sauce for the mac and a bean-based chili without animal products.

Gluten-free: Swap to certified gluten-free pasta and ensure all other ingredients are labeled gluten-free.

FAQ

Can you use leftover mac and cheese in this casserole? It’s best to use freshly prepared mac and cheese for this recipe. Leftover mac and cheese can be drier or clumpier and doesn’t blend as smoothly with the chili.

Can you use any chili or mac and cheese recipe? Yes. For this casserole, plan on using approximately 6 cups of mac and cheese and 6 cups of chili (about three-quarters of a typical large chili batch) so the proportions are balanced.

Storage

Store leftover chili mac in an airtight container in the refrigerator for up to five days. Reheat individual portions in the microwave or reheat the whole casserole in an oven-safe dish at 350°F (175°C). If the casserole seems dry, stir in a splash of broth or tomato sauce before reheating to restore creaminess.

Freezing Chili Mac

You can freeze this casserole for up to three months. Allow it to cool completely, then transfer to a freezer-safe container. Thaw overnight in the refrigerator before reheating in the oven. To prevent the pasta from becoming overly soft after freezing, cook the macaroni slightly less than al dente when making the mac and cheese for batches you intend to freeze.

Serving Suggestions

Serve chili mac with a simple green or roasted vegetable side to balance the richness. Popular choices include roasted broccoli, a crisp arugula salad, or baked zucchini. Garnish each serving with a dollop of sour cream or Greek yogurt, a sprinkle of shredded cheddar, diced red onion, and chopped green onions.

Chili Mac Recipe

This homemade chili mac combines hearty beef chili with creamy mac and cheese to make a filling, family-friendly casserole.

Ingredients (serves about 12)

  • 6 cups homemade mac and cheese (one full mac and cheese recipe)
  • 6 cups beef chili (about three-quarters of a full chili recipe)
  • 1 cup shredded cheddar cheese, for topping

Instructions

  1. Prepare a creamy homemade mac and cheese. For best texture, make it fresh the day you assemble the casserole.
  2. Prepare a robust beef chili and warm it through. If using leftover chili, reheat it before assembling.
  3. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
  4. In the prepared dish, combine the 6 cups of mac and cheese with 6 cups of beef chili. Stir until evenly mixed.
  5. Bake the casserole for 15 minutes until hot and bubbling around the edges.
  6. Remove from the oven, sprinkle the shredded cheddar evenly over the top, and return to the oven for 4–6 minutes until the cheese melts.
  7. Let the casserole rest for 5–10 minutes before serving. Top bowls with Greek yogurt or sour cream if desired.

Tips & Notes

  • Storage: Refrigerate leftovers in an airtight container for up to five days. Reheat with a splash of broth or tomato sauce to revive creaminess.
  • Freezing: Cool completely and freeze for up to three months. Thaw in the refrigerator before reheating in the oven. For freezing, slightly undercook the pasta initially to prevent a mushy texture when reheated.
  • Portioning: This recipe scales well. Adjust quantities proportionally if you want a smaller batch.
