How to Thicken Chili Fast (14 Easy Pantry-Staple Fixes)
How to thicken chili fast usually comes down to one simple fix, stir in a starch like cornstarch, flour, or masa harina, mash extra beans into the pot, or take the lid off so the liquid can reduce. Chili turns watery from adding too much liquid at the start, fresh tomatoes releasing extra moisture, or not simmering long enough, and any of the fourteen methods below will fix it without changing the flavor. If you only try one thing, a cornstarch slurry is the most reliable fix; it works in about ten minutes and won’t change the taste at all. This post covers all fourteen tested methods, plus what causes watery chili in the first place so it doesn’t happen again.
I am a homeschool mom of six, so I will be the first to admit my mind is not always in one place at once, and one particularly chaotic afternoon proved it. I had six kids doing six different things around me, and somewhere between refereeing a math worksheet and hunting down somebody’s missing shoe, I dumped way more broth into the pot than the recipe called for. By dinner time I lifted the lid and what I had was closer to chili soup than chili, and with a table full of hungry kids waiting, starting over was not an option. I grabbed the flour and butter I already had out for biscuits, whisked up a quick roux right there in a separate pan, and stirred it back into the pot, and honestly, nobody at that table ever knew the difference. That is really how most of these methods became part of my regular rotation, not from a cookbook, but from a kitchen full of kids and a pot that needed rescuing fast.
What You Need to Know Before You Thicken Watery Chili
Here’s a quick look at what we’ll cover. Jump to any section that’s most helpful for you: fourteen ways to thicken chili using things you probably already have, real variations for different chili types, what you can do ahead of time, and a few things worth knowing before you start.
First, it helps to know why chili turns out watery in the first place. Most of the time it comes down to one of four things: too much broth or liquid added at the start, fresh tomatoes releasing extra water as they cook, frozen vegetables added without draining first, or simply not enough time on the stove or in the slow cooker for the liquid to reduce. None of these mean you did anything wrong, chili is forgiving, and every method below works whether the problem happened five minutes ago or you’re only noticing it now that the lid is off.
If you’re short on time, cornstarch, arrowroot, and xanthan gum are your fastest options, all of them thicken in ten minutes or less. Flour, masa harina, and cornmeal need a little more patience, plan on twenty to thirty minutes of simmering. Removing the lid is the slowest method by far, especially in a slow cooker, where it can take a few hours instead of minutes.
A few quick answers before you dive into a method: no, thickening chili the right way will not water down the flavor, most of these methods actually deepen it. You do not need special equipment, everything below uses what is already in a normal kitchen. And you can absolutely combine two methods if your chili is especially thin, removing the lid while you stir in a slurry works well together.
How To Thicken Chili
After cooking your chili all day in your slow cooker or simmering on your stovetop, it’s disappointing to lift the lid and find out it’s too watery. Don’t worry. I have 14 great tips for how to thicken chili and soup. Here, you will find several different ways to make your watery chili become thick and hearty.
Tortilla Chips
This is my personal favorite method, and it doubles as a way to use up the ends of a bag nobody wants to eat plain. Crush five to six ounces of tortilla chips into small crumbly pieces and stir them into the pot. If you’re using a slow cooker, switch it to high with the lid off and stir every five minutes for about thirty minutes. On the stovetop, add the chips and simmer on medium, stirring every few minutes until the chili reaches the thickness you want. The chips soak up liquid and mostly dissolve, so you get thickness without a strong corn flavor taking over.
Cornstarch
Mix two to three tablespoons of cornstarch with an equal amount of cold water in a small jar with a tight lid and shake until smooth. Scoop out about four cups of the liquid from your chili into a small saucepan and bring it to a boil. Whisk the cornstarch slurry into the boiling liquid until it thickens, then pour it back into the pot and stir it through. Tip: always mix cornstarch with cold water first, never add it dry straight to the hot pot, or you will end up with lumps instead of a smooth thickener.
Flour
Flour to thicken chili is the method I reach for most, especially when I’ve already got butter out for something else. Melt five tablespoons of butter in a separate pan over medium-high heat and whisk in two tablespoons of all-purpose flour until it forms a smooth, thick paste. This is the roux method, and cooking the flour in butter first is what keeps it from turning lumpy in the pot. Ladle out some of the liquid from your chili and whisk it into the roux over medium heat until smooth, then stir the whole mixture back into the slow cooker or pot and let it cook on high for about thirty minutes. This works equally well for stovetop chili and crock pot chili.
Masa Harina
Masa harina is corn flour, and it is the method behind a lot of restaurant-style chili, including a Texas Roadhouse copycat I make often. Turn your pot or slow cooker to high and stir in two tablespoons at a time, waiting about ten minutes between additions to see how much it has thickened before adding more. It will add a light corn flavor, which works especially well in a Tex-Mex style chili.
Cornmeal
Stir in one tablespoon of cornmeal and cook on high for twenty minutes, then check the thickness and repeat if you want it thicker still. Cornmeal works fast, but it can leave a slightly gritty texture behind, so it is best in a chili where you already expect some texture rather than a smooth one.
Beans, Mashed or Blended
Adding pinto beans, black beans, kidney beans, or navy beans is one of the easiest fixes, and the starch in the beans does most of the work. For extra thickness without changing the flavor, scoop out a cup or two of beans and chili, blend them smooth, and stir the mixture back into the pot. If you’d rather skip the blender, press a potato masher against the beans right in the pot until they break down, the starch they release will thicken the chili while still leaving some beans whole. Lentils work the same way if you want the thickening effect without a strong bean flavor. If you don’t love the texture of beans at all, a can of refried beans stirred in gives you the same thickening power with a smoother finish.
If you love beans as much as I do, my how to can beans post will save you money over store-bought cans, and homemade beans hold their texture in chili better than most canned varieties.
Tomato Paste
A small six-ounce can of tomato paste whisked into the pot adds a tangy thickness fast, since the paste is so concentrated. Simmer on high for about an hour after adding it. You may want to add a bit more seasoning afterward, since tomato paste can shift the chili toward a more tomato-forward flavor than you started with.
Potato Flakes or Potato Starch
Stir in half a cup of instant potato flakes with the lid off and the heat on high, then let it simmer for about thirty minutes. Potato starch works the same way in a smaller amount, a tablespoon or two is usually enough, and it holds up to higher heat than cornstarch without breaking down.
Rice
A half cup of uncooked white rice stirred into the pot will absorb liquid as it cooks, working the same starch principle as the potato flakes. Give it at least twenty minutes to soften and thicken the chili around it. This one is worth knowing if you already have rice on hand and don’t want to reach for a specialty ingredient.
Crackers
My husband’s favorite way to eat chili is with a handful of crushed saltine crackers stirred right in, or oyster crackers if that’s what’s in the pantry. The crackers soak up the extra liquid as they sit, and nobody at the table will ever guess the chili started out too thin.
Arrowroot Powder
Mix a teaspoon of arrowroot powder with cold water to make a slurry, then stir it into the chili and simmer for ten to fifteen minutes on low heat. Like cornstarch, arrowroot is a powerful thickener, so start small and add more only if you need it.
Xanthan Gum
A small pinch of xanthan gum stirred thoroughly into the pot goes a long way, this one surprised me the first time I tried it. Let it simmer a few minutes to fully thicken before deciding if you need more, since a little goes further than you’d expect.
Add More Meat
If your chili is thin because it needs more body rather than less liquid, browning up extra ground beef, ground turkey, or ground sausage in a separate pan and stirring it in can solve the problem without adding any starch at all. Drain the excess grease before adding it to the pot, then let everything heat through together for twenty to thirty minutes. My ground turkey chili recipe uses this exact approach if you want a lighter starting point.
Remove the Lid and Simmer
The simplest fix of all costs nothing extra: take the lid off and let the liquid evaporate. On the stovetop, bring the chili to a steady simmer and stir often so nothing sticks to the bottom. If you’re wondering how to thicken chili in a crock pot specifically, the same principle applies; just switch it to high with the lid off and give it a few hours, since evaporation takes longer without direct heat than it does over direct stovetop heat.
Tip: this method takes patience, but it’s the only one that thickens chili without adding a single new ingredient or changing the flavor at all.
Chili Thickening Variations
Not every chili needs the same fix. My white chicken chili or a vegetarian chili without much fat in the pot tends to respond best to the starchier methods, potato flakes, rice, or masa, since there’s no meat fat to help carry a roux. A heavier beef chili can handle the flour and butter roux beautifully since it already has richness to match.
If you’re working with my no bean chili, cornstarch or arrowroot are your best friends since you don’t have the natural bean starch to lean on the way a bean-based chili does. And if you’ve gone the other direction and your chili is now too thick, a splash of broth or water stirred in over low heat will loosen it right back up, no need to start the whole pot over.
Planning Ahead When You Thicken Chili
If you know you’re serving a crowd, you can thicken your chili the day before and let it sit in the refrigerator overnight; chili actually thickens more as it rests, so a pot that seemed just right the night before often needs a splash of broth to loosen back up before reheating. This makes chili a genuinely good make-ahead option for a potluck or a busy week; you can solve the watery problem well before anyone is sitting at the table waiting. If you’re freezing a batch, know that starch-based thickeners like flour and cornstarch can separate slightly once thawed, so give the chili a good stir over low heat after reheating, and it will come back together.
Showing Hospitality With a Thick Pot of Chili
A good pot of chili is one of those meals that lets you actually sit down with people instead of hovering over the stove the whole night, and that’s exactly why I love building a Chili Bar Night around it. Set out a big pot of chili with bowls of shredded cheese, sour cream, and crushed crackers on the side, let everyone build their own bowl, and you’ve got a meal that feeds a crowd without a lick of fuss. I think
