Chili and macaroni cheese in one pot, with three kinds of bean and the pasta cooked directly in the chili.

The meat is optional throughout, which makes this one recipe that genuinely serves both halves of a table.

Why This Recipe Works

  • Three beans rather than one gives three textures — kidney stays firm, black holds its shape, pinto softens into the sauce and thickens it.
  • Cooking the macaroni in the chili rather than separately means it absorbs the spice and releases its starch back into the pot, which is what makes it cling.
  • A tablespoon of brown sugar against 28 ounces of crushed tomatoes is a small correction that stops the pot tasting sharp. It is optional; it is worth doing.
  • Lime juice or cider vinegar at the very end lifts a dish that has been simmering for seven hours. Long cooking flattens acidity and this puts it back.

Brown, or Not to Brown

The first step is a question: do you brown the meat and sweat the aromatics in a skillet first, or does everything go into the crock raw?

You have ten extra minutes and want the deepest flavour

Brown the ground beef or turkey over medium-high with a pinch of salt until no pink remains, 6 to 8 minutes, and drain. In the same pan, soften the onion and bell pepper in olive oil for 3 to 4 minutes, then the garlic for 30 seconds.

Browning is a chemical change, not just a colour one, and a slow cooker cannot produce it at any length of time — the pot never gets hot enough or dry enough. The fond left in the pan is what makes 'a rich base'.

You are short on time, or making it meat-free

Skip the skillet entirely and add everything to the slow cooker raw. The result is still delicious but slightly less complex.

With three cans of beans, crushed tomatoes and two tablespoons of chili powder already in the pot, there is plenty of flavour without the browning stage. This is also the route that makes the recipe vegetarian, since the meat is marked optional.

You skip the skillet AND you are using meat

Use fully thawed meat only, and check it with a thermometer before serving — 160°F (71°C) for ground beef, 165°F (74°C) for ground turkey.

This is the warning in step 7. Frozen meat in a slow cooker spends too long in the temperature range where bacteria multiply, and raw meat added straight to a crock gives you no browning cue to judge it by afterwards.

Ingredient Notes

Ground beef or turkey
One pound, and optional. Leaving it out and using vegetable broth makes the whole recipe vegetarian without changing anything else.
Two cups of hot broth or water, separately listed
This is a second liquid line existing only for the pasta stage. It is easy to read as part of the two cups already in the chili and pour it all in at the start.
Dry elbow macaroni
A cup and a half, added dry with 20 to 25 minutes left. Slow cookers vary enough that you should start checking at 15.

How to Make It

  1. Brown, or don't

    For the deepest flavour, brown the ground beef or turkey with a pinch of salt until no pink remains, 6 to 8 minutes, and drain. In the same pan, sauté the onion and bell pepper in olive oil 3 to 4 minutes, then the garlic for 30 seconds. Short on time, add everything raw instead.

  2. Load the slow cooker

    Add the meat if using, the aromatics, the rinsed beans, crushed tomatoes, tomatoes with green chiles, broth, chili powder, cumin, smoked paprika, oregano, salt, pepper and the optional brown sugar. Stir well.

  3. Cook

    Low for 6 to 7 hours or High for 3 to 4, melding the flavours and tenderising the beans while keeping them intact.

  4. Add the macaroni

    Switch to High. Stir in the dry elbow macaroni and 2 cups of hot water or broth. Cover and cook 20 to 25 minutes, stirring once halfway, just until al dente — start checking at 15 to 18 minutes. Add another half to one cup of hot liquid if it thickens too far, or uncover on High for a few minutes if it is too thin.

  5. Finish with cheese

    Stir in the shredded cheddar until glossy and melted, then adjust the salt, pepper and heat. A squeeze of lime or a splash of cider vinegar at the end brightens the pot.

  6. Serve

    Ladle into bowls and set out sour cream, green onions, cilantro, jalapeños, avocado and hot sauce.

  7. Check the meat

    Judge the meat with a food thermometer rather than by colour: ground beef must reach at least 160°F (71°C) and ground turkey at least 165°F (74°C). If you added the meat raw, use fully thawed meat only — never put frozen meat into a slow cooker.

Success Tips

  • Rinse and drain the beans. Canning liquid is starchy and salty and there are three cans of it here.
  • Start checking the pasta early. This is the one stage a slow cooker's variability really shows.
  • Correct the consistency while the pasta cooks, not after.
  • Use the thermometer if you added the meat raw.

Serving Ideas

The full toppings bar — sour cream, green onions, cilantro, jalapeños, avocado, hot sauce. A pot this thick benefits from something cool and something sharp on top.

Storage and Reheating

Refrigerate

Refrigerate up to 4 days. The macaroni keeps absorbing liquid, so leftovers are noticeably thicker.

Freeze

Freeze before the pasta stage up to 3 months, then cook the macaroni fresh into the reheated chili. Frozen cooked pasta goes mealy.

Reheat

On the stove with a splash of broth to loosen it, stirring so the cheese re-emulsifies rather than sitting on top.

Frequently Asked Questions

Is this vegetarian?

It can be, without any substitution work. The meat is optional in the ingredient list — leave it out and use vegetable broth in both places, and the three cans of beans carry the dish.

My macaroni went to mush. What happened?

It was in too long, which happens easily because slow cookers vary. Begin checking at 15 to 18 minutes rather than trusting the 20 to 25 minute range. Cooking it separately and stirring it in is the reliable fix.

It went too thick before the pasta was done.

Splash in another half to one cup of hot liquid, which is built into step 4. The pasta drinks more than expected, especially if the chili was already reduced.

Ingredients

Instructions

  1. 1) Brown or not to brown? For the deepest flavor, heat a skillet over medium-high and brown the ground beef (or turkey) with a pinch of salt until no pink remains, 6–8 minutes. Drain excess fat. In the same pan, sauté onion and bell pepper in a splash of olive oil for 3–4 minutes, then stir in garlic for 30 seconds. This step builds a rich base. Short on time? You can skip the skillet and add everything raw to the slow cooker; the result will still be delicious, just slightly less complex.
  2. 2) Load the slow cooker: Add the browned meat (if using), sautéed aromatics, beans (rinsed and drained), crushed tomatoes, diced tomatoes with green chiles, broth, chili powder, cumin, smoked paprika, oregano, salt, pepper, and optional brown sugar. Stir well to combine.
  3. 3) Cook low and slow: Cover and cook on Low for 6–7 hours or on High for 3–4 hours. The goal here is melding flavors and tenderizing the beans while keeping them intact.
  4. 4) Add the macaroni: Switch to High. Stir in the dry elbow macaroni and 2 cups of hot water or broth. Cover and cook for 20–25 minutes, stirring once halfway through, just until the pasta is al dente. Slow cookers vary; begin checking around 15–18 minutes. If the mixture looks too thick before the pasta softens, splash in another 1/2 to 1 cup hot liquid. If it’s too thin after the pasta cooks, uncover and let it bubble on High for a few minutes to reduce.
  5. 5) Finish with cheese: Stir in shredded cheddar until glossy and melted. Taste and adjust salt, pepper, and heat. A small squeeze of lime or splash of apple cider vinegar at the end brightens and balances the dish.
  6. 6) Serve and top: Ladle into bowls and set out toppings—sour cream, sliced green onions, chopped cilantro, jalapeños, avocado, and hot sauce.
  7. Food-safety checkpoint: judge the meat with a food thermometer, not by colour. Ground beef must reach at least 160°F (71°C) and ground turkey at least 165°F (74°C) before the chili is served. If you skip the skillet and add the meat raw, use fully thawed meat only — never put frozen meat into a slow cooker.
