With minimal cleanup and maximum taste, One-Pot Chili Mac Soup has earned its place as a modern classic in home cooking.

The History

The roots of One-Pot Chili Mac Soup can be traced back to two beloved American dishes: chili con carne and macaroni and cheese. Chili, with origins in Texas in the 19th century, was traditionally made with beef, chilies, and spices, often cooked slowly over open flames. Macaroni and cheese, introduced to America by Thomas Jefferson after his travels in Europe, became a staple due to its affordability and comforting nature. Over time, home cooks began combining these two favorites into a hybrid dish known as “chili mac,” typically baked or stovetop-prepared with ground beef, tomatoes, beans, and elbow macaroni smothered in a spicy tomato sauce and topped with melted cheese.

The evolution into a soupy version—Chili Mac Soup—emerged as a response to the desire for lighter, more brothy iterations of classic comfort foods. By incorporating broth or water and adjusting ingredient ratios, chefs and home cooks transformed the dense casserole into a cozy, spoonable soup. The “one-pot” aspect gained popularity with the rise of quick, efficient meal prep trends in the late 20th and early 21st centuries, aligning perfectly with the growing demand for simple, time-saving recipes. Today, One-Pot Chili Mac Soup stands as a symbol of culinary innovation, blending tradition with convenience and evolving with dietary preferences—from meat-based versions to vegetarian and even vegan adaptations.

Ingredients Breakdown

The magic of One-Pot Chili Mac Soup lies in its balance of flavors, textures, and simplicity. Here’s a detailed breakdown of each ingredient and its role in creating this delectable dish:

Ground Beef (or alternative protein): Provides a rich, savory base. Lean ground beef keeps fat content moderate, while chuck offers deeper flavor. Vegetarian options include lentils, plant-based crumbles, or mushrooms.
Onion and Garlic: Essential aromatics that build depth and complexity. Yellow onion adds sweetness when sautéed, while garlic contributes a pungent, earthy note.
Green Bell Pepper: Adds mild bitterness and crunch, balancing the richness. It also boosts vitamin C and color contrast.
Tomato Paste: Concentrated tomato flavor that deepens the umami profile. Cooking it briefly with the vegetables enhances its sweetness and reduces acidity.
Crushed Tomatoes and Diced Tomatoes: Crushed tomatoes provide body and smooth texture, while diced tomatoes add chunkiness and freshness. Together, they form the backbone of the soup’s tangy, slightly sweet liquid base.
Beef or Vegetable Broth: Adds savory depth and moisture. Low-sodium versions allow better control over salt levels. Chicken broth can also work in a pinch.
Dry Elbow Macaroni: The star starch component. Elbows hold sauce well and absorb flavors beautifully. Gluten-free pasta works for those with sensitivities.
Beans (Kidney or Pinto): Add fiber, protein, and heartiness. Kidney beans have a firmer texture and earthy taste, while pinto beans are creamier and milder.
Chili Powder: A blend of ground chilies, cumin, garlic powder, and other spices. It gives the soup its signature warmth and red hue.
Smoked Paprika: Imparts a subtle smokiness, enhancing depth without excessive heat. Sweet paprika can substitute if smokiness isn’t desired.
Cumin: Earthy and warm, cumin complements beef and beans, anchoring the Southwestern flavor profile.
Oregano: A dried herb that adds a slightly floral, peppery note common in Mexican and Tex-Mex cuisine.
Bay Leaf: Infuses a woodsy, herbal aroma during cooking. Removed before serving to avoid bitterness.
Salt and Black Pepper: Fundamental seasonings that enhance all other flavors. Adjust to taste throughout cooking.
Shredded Cheddar Cheese: Melts into the soup for creaminess and tang. Sharp cheddar intensifies flavor, while mild cheddar blends smoothly.
Milk or Cream (optional): Adds silkiness and balances acidity. Whole milk, half-and-half, or evaporated milk work well.
Optional Toppings: Sour cream, sliced jalapeños, green onions, fresh cilantro, crushed tortilla chips, avocado slices—each adds contrasting texture and brightness.

Step-by-Step Recipe

Prepare Ingredients: Dice one medium yellow onion, mince 3 cloves of garlic, chop one green bell pepper into small pieces, drain and rinse two cans of beans, shred 2 cups of cheddar cheese, and measure out all spices and liquids.
Heat the Pot: Place a large Dutch oven or heavy-bottomed pot over medium heat. Add 1 tablespoon of olive oil or vegetable oil and allow it to shimmer.
Brown the Meat: Add 1 pound of ground beef (or plant-based alternative). Cook, breaking it apart with a spoon, until browned and no longer pink (about 6–8 minutes). Drain excess grease if necessary.
Sauté Aromatics: Add the diced onion, green bell pepper, and minced garlic to the pot. Stir and cook for 5–7 minutes until softened and fragrant.
Bloom the Spices: Stir in 2 tablespoons of tomato paste, 2 teaspoons of chili powder, 1 teaspoon of smoked paprika, 1 teaspoon of ground cumin, ½ teaspoon of dried oregano, salt, and black pepper. Cook for 1–2 minutes to toast the spices and deepen their flavor.
Add Liquids and Tomatoes: Pour in one 28-ounce can of crushed tomatoes, one 14.5-ounce can of diced tomatoes (with juice), and 3 cups of beef or vegetable broth. Stir well to combine.
Incorporate Pasta and Beans: Add 1 cup of dry elbow macaroni and two 15-ounce cans of drained and rinsed kidney or pinto beans. Drop in one bay leaf.
Simmer Until Tender: Bring the mixture to a boil, then reduce heat to low. Cover partially and simmer for 15–20 minutes, stirring occasionally, until the pasta is al dente and has absorbed much of the liquid.
Adjust Seasoning: Remove the bay leaf. Taste and adjust salt, pepper, and spices as needed. For extra heat, add a dash of cayenne or hot sauce.
Add Cheese and Cream: Reduce heat to low. Stir in shredded cheddar cheese until melted. For a creamier texture, add ½ cup of milk or cream, stirring gently.
Rest and Thicken: Let the soup sit off heat for 5 minutes. The pasta will continue absorbing liquid, thickening the soup slightly.
Serve Warm: Ladle into bowls and garnish with your favorite toppings. Serve immediately with crusty bread or cornbread on the side.

Tips

Don’t Overcook the Pasta: Since the macaroni continues to absorb liquid even after cooking, aim for al dente doneness to prevent mushiness.
Bloom the Spices: Toasting spices with tomato paste and vegetables unlocks their essential oils, significantly boosting flavor.
Use Low-Sodium Broth: This allows you to control the salt level and avoid an overly salty soup.
Stir Occasionally: Prevents sticking and ensures even cooking, especially important when using non-stick pots.
Reserve Some Cheese: Melt most of the cheese into the soup, but save a portion for topping each bowl for visual appeal and extra cheesiness.
Enhance Umami: Add a splash of Worcestershire sauce or a teaspoon of soy sauce to deepen savory notes without making the soup taste salty.
Acidity Balance: If the soup tastes flat, brighten it with a squeeze of fresh lime juice or a dash of apple cider vinegar.
Make Ahead: While best served fresh, you can prepare the base (without pasta) ahead of time and add cooked macaroni later to maintain texture.
Freezing Caution: Due to the pasta absorbing liquid upon reheating, freezing is not ideal. If necessary, freeze without pasta and add freshly cooked macaroni when reheating.
Thinning the Soup: If the soup thickens too much in leftovers, stir in additional broth or water when reheating.

Variations and Customizations

One of the greatest strengths of One-Pot Chili Mac Soup is its adaptability. Here are numerous ways to customize it to suit different diets, tastes, and occasions:

Vegetarian/Vegan Version: Omit meat and use plant-based crumbles, lentils, or extra beans. Substitute vegetable broth and use vegan cheese and unsweetened plant-based milk (like cashew or oat).
Turkey or Chicken Chili Mac: Use ground turkey or shredded cooked chicken for a leaner protein option. Pair with poultry-friendly spices like sage or thyme for variation.
Spicy Kick: Add diced jalapeños, crushed red pepper flakes, chipotle peppers in adobo sauce, or a few dashes of hot sauce for heat lovers.
White Bean & Chicken Version: Replace tomato base with white beans, chicken broth, and mild spices for a creamy, pale version reminiscent of chicken stew.
Gluten-Free: Use certified gluten-free pasta (corn, rice, or chickpea-based) and ensure all other ingredients (like broth and spices) are GF-safe.
Dairy-Free: Skip cheese and cream; instead, blend silken tofu or cashews into the soup for creaminess.
Instant Pot Method: Sauté ingredients using the sauté function, then pressure cook on high for 4 minutes with quick release. Stir in cheese afterward.
Slow Cooker Version: Brown meat and sauté veggies first, then transfer to a slow cooker with all ingredients except pasta and cheese. Add uncooked pasta in the last hour and cheese at the end.
Loaded Toppings Bar: Turn it into a fun dinner party dish by setting up a topping station with sour cream, avocado, pickled red onions, radishes, shredded cheese, cilantro, and hot sauces.
Tex-Mex Twist: Add corn, black beans, taco seasoning, and top with crushed tortilla chips and salsa.
Italian-Inspired: Swap chili powder for Italian seasoning, use marinara sauce, and top with Parmesan and basil.
Kid-Friendly: Reduce spices, increase cheese, and use mild tomatoes. Call it “Cheesy Beef Pasta Soup” for picky eaters.

Yes, you can prepare the soup base (without pasta) in advance and refrigerate for up to 3 days. Add freshly cooked pasta when reheating to maintain texture.

How do I store leftovers?
Cool completely and store in an airtight container in the refrigerator for up to 4 days. Reheat on the stove with a splash of broth to loosen the consistency.

Can I freeze Chili Mac Soup?
It’s not recommended due to the pasta becoming mushy upon thawing and reheating. If freezing, omit the pasta and add it fresh when serving.
