5 Tips for Thickening Slow Cooker Soups, Stews, and Sauces (2024)

FAQs

What is the best way to thicken stew in slow cooker? ›

Cornstarch, potato starch, and chickpea flour are a couple of pantry-friendly ways to thicken soups, stews, and sauces in the slow cooker. Just a tablespoon or two of any — added towards the end of cooking — will thicken sauces especially well.

Whisk a teaspoon of flour in a little cold water to make a slurry, then stir into the stew as it's cooking. Don't add dry flour directly to the stew as it may clump. After adding the slurry, bring the stew to boil. This will cook out the flour taste and allow the starch to swell.

The three main thickening agents for gravies are flour, cornflour and arrowroot. The first two are normally used in savoury dishes while arrowroot tends to be used in sweet dishes – that said, arrowroot will work in a savoury dish as it has no flavour.

If you have time at the end of cooking, take the lid off the slow cooker, turn up the heat and allow some of the liquid to evaporate. Prop the lid open. If you've previously cooked a recipe with watery results, some sources suggest propping the lid open with a toothpick.

Cornstarch will thicken stew similar to flour, but has the added benefit of being flavorless and won't cloud the liquid as much. It's also gluten-free but has to be added carefully to avoided gloppy lumps. One tablespoon cornstarch per cup of liquid will give you a medium-thick stew that's not overly viscous.

A slurry is a mixture of some type of starch, usually cornstarch, and water—use cold water, hot water, or the hot liquid from the stew. Mix the starch and liquid together, add it to the stew, and bring everything to a boil. The stew will start to thicken almost immediately without much impact to the total cooking time.

Use cornstarch at the end of the cooking time. In a little bowl stir together a couple of tablespoons of cornstarch and a couple tablespoons water. Turn the slow cooker to high and stir in the cornstarch mixture. Keep the lid off and let the sauce get thickened up.

You'll most likely be using potatoes, and their starch will naturally thicken your stew. It's not a gravy—you shouldn't be adding a roux or flour or cornstarch.

Simply add two tablespoons of flour to every cup of liquid and cook it for a few minutes until it thickens. You can also mash up some cooked potatoes and whisk them into the sauce; this will add body and flavor as well as a bit of thickness.

Give stew plenty of time

For most types of stew, it takes time to develop great flavor. Stew uses collagen-rich, tough cuts of meat, which need at least two hours to break down. If you try to rush it and boil the stew, the muscle fibers will shrink and become tough. So give yourself a few hours to let it do its thing.

How long does it take for stew to thicken? ›

Thickening Stew in a Slow Cooker

If you're using the flour or cornstarch slurry method, add the mixture at the last 30 minutes of cooking. This is enough time to cook the starch and thicken the soup.

Start by cooking your stew without the lid on for a bit longer—this will allow for more of the liquid to evaporate and let the stew reduce. (Cooking with a lid on traps the moisture inside instead of letting it cook off.)

The sauce should thicken as it cooks and it is easy to add extra cornfliur if the sauce should be thicker. You can also thicken the sauce using a beurre manie which is a paste made from equal quantities of softened unsalted butter and plain (all-purpose) flour.

Due to the nature of a slow cooker, there is no need to stir the food unless it specifically says to in your recipe. In fact, taking the lid off to stir food causes the slow cooker to lose a significant amount of heat, extending the cooking time required. Therefore, it is best not to remove the lid for stirring.

How do you make a sauce thicker? The easiest way to thicken a sauce is by reducing the amount of liquid. This can be done by simmering your sauce or bringing it to a full boil—do this uncovered, so the steam can escape.

Whisk together the cornstarch and water in a small bowl until fully combined. Pour the mixture into the hot liquid you plan to thicken: stir fry sauce, soup, stew, fruit compote or sauce, etc. Stir constantly and the sauce should thicken in about 30 seconds to 1 minute.

Cooking a soup, stew, or sauce uncovered allows water to evaporate, so if your goal is to reduce a sauce or thicken a soup, skip the lid. The longer you cook your dish, the more water that will evaporate and the thicker the liquid becomes—that means the flavors become more concentrated, too.

If it tastes off-balance, add some finishing flavors to bring it to the next level. Try adding soy sauce or Worcestershire for extra savory (or umami) flavor, a touch of honey or brown sugar for sweetness, lemon zest or vinegar for brightness or chili powder or smoked paprika for spice and depth.

Add Flour, Cornstarch, or Other Thickener: Starches thicken soup and give it body. Whisk a few tablespoons of starch into a little of the broth in a separate bowl before whisking it into the main pot. This prevents the starch from clumping and helps it dissolve into the soup evenly.

Both whole milk and fat free will work, though you'll get a richer soup with whole milk. Spoon it into the soup near the end, and let it simmer for a few minutes to thicken.

What is the slow cooker tea towel trick? ›

You will often see in recipes that people will state to lay a tea towel (the cloth you dry your dishes with) between the inner slow cookerbowl top and the lid of the slow cooker (see photo below). This is to absorb condensation and stop it from dripping down into the dish inside. Thank you!

When cooking meat or poultry, the water or liquid level should cover the ingredients to ensure effective heat transfer throughout the crock. Some manufacturers of slow cookers recommend adding liquid to fill the stoneware 1/2 to 3/4 full.

If you add too much liquid to your recipe, it will become very hot and cause excess condensation, which will drip from the lid back into your dish and make the recipe too watery. Ladle out the excess before cooking, if you find there's too much.

Can you overcook something in a slow cooker? Slow cookers are specially designed to cook food for long periods of time, but yes, you can still overcook in a slow cooker if something is left on the wrong setting for longer than it's supposed to be.

The most straightforward way to thicken soup is to puree the vegetables. Starchy vegetables in particular offer the most creaminess. Try with corn, parsnips, potatoes, sweet potatoes, squash, or yams. Blend half (for a chunkier texture) or all of the vegetables and liquid together.

Yes. Incredibly effective? You bet. This trick works because the instant mashed potatoes are naturally starchy and therefore are similar in form to other commonly used thickeners, such as cornstarch, only without the clumps.

Use Flour and Water

Combine 2 tablespoons flour with every 1/4 cup cold water and whisk until smooth. Add the mixture to your sauce over medium heat, and continue to stir and cook until you've reached your desired consistency. Test with a spoon.

To use flour as a thickening agent: Use two tablespoons flour mixed with ¼ cup cold water for each cup of medium-thick sauce. Thoroughly mix in the water to prevent lumps. After stirring the combined flour and water into the sauce, cook and stir over medium heat until thickened and bubbly.

All-purpose flour: You can thicken sauces with all-purpose wheat flour. For every tablespoon of cornstarch, use three tablespoons of flour. Combine raw flour with cold water in a small bowl to form a paste, then add it into the sauce as it's simmering. Cooking the flour in the sauce will remove the flour taste.

Simply knead equal parts softened butter and flour together in a bowl with your fingers until well-combined (beurre manié literally means “kneaded butter”) and then roll into small bits. Add the bits gradually to your stew, whisking until it noticeably thickens.

How do I reduce the liquid in my slow cooker? ›

Here's one easy solution: Prop the lid open with a wooden or chopstick to let steam escape as it's cooking. This will allow the liquid to reduce and result in a thicker, more velvety texture.
