Why Does Crockpot Beef Stew Turn Out Thin?
Slow cookers (or crockpots) are great for making beef stew because they gently cook the ingredients over several hours, developing deep flavors and tender meat. However, the sealed environment of a crockpot means moisture doesn’t evaporate like it does on the stovetop. This can leave your stew with a thinner broth than you might expect.
How to Thicken Crockpot Beef Stew: 7 Simple Methods
Here are seven tried-and-true ways to thicken your crockpot beef stew. Choose the one that works best for you based on what you have in your kitchen and your personal taste preferences.
1. Cornstarch Slurry
What it is: A cornstarch slurry is simply cornstarch mixed with cold water.
- How to use: Mix 1-2 tablespoons of cornstarch with an equal amount of cold water until smooth. Stir this mixture into your hot stew about 30 minutes before serving. Let it cook uncovered on high so the sauce thickens up nicely.
- Tip: Don’t add cornstarch directly to hot liquid—it will clump!
2. Flour Slurry
What it is: Like cornstarch, flour can be used to thicken stews by making a slurry.
- How to use: Combine 2 tablespoons of all-purpose flour with about 1/4 cup of cold water. Whisk until smooth, then stir into your stew. Let it cook for another 30 minutes on high, uncovered, to thicken.
- Tip: Make sure the flour is well-mixed with water to avoid lumps.
3. Instant Potato Flakes
What it is: Potato flakes are a quick and easy thickener that also add a creamy texture.
- How to use: Sprinkle 1-2 tablespoons of instant potato flakes directly into the stew. Stir well and let it sit for a few minutes; the flakes will absorb liquid and thicken the sauce.
- Tip: Add gradually—too much can make your stew gluey.
4. Mashed Vegetables
What it is: Use some of the cooked potatoes or carrots from your stew to naturally thicken it.
- How to use: Remove a cup or so of cooked vegetables from the crockpot, mash them well, then stir them back into the stew. The starches help create a thicker consistency.
- Tip: This method adds flavor and keeps your stew gluten-free.
5. Arrowroot Powder
What it is: Arrowroot is a plant-based thickener similar to cornstarch and works well in slow cooker recipes.
- How to use: Mix 1 tablespoon arrowroot powder with 1 tablespoon cold water to make a slurry. Stir into the stew and cook for about 10-15 minutes on high until thickened.
- Tip: Arrowroot creates a glossy finish and works great for gluten-free diets.
6. Reduce the Liquid
If you have time, you can thicken your stew by letting some of the liquid evaporate.
- How to use: Remove the lid from your crockpot during the last hour of cooking and turn the heat up to high. This will help excess moisture evaporate and naturally thicken the stew.
- Tip: Stir occasionally to prevent sticking or burning at the bottom.
7. Add a Beurre Manié (Butter-Flour Paste)
What it is: Beurre manié is a French technique where equal parts butter and flour are kneaded together into a paste.
- How to use: Mix softened butter with flour (about 1 tablespoon each), then stir small pieces into your hot stew. Let it melt and cook for a few minutes—your stew will thicken beautifully and gain a rich flavor.
- Tip: This method adds a subtle buttery taste as well as thickness.
Tips for Avoiding Watery Stew in the First Place
- Brown Your Meat First: Searing beef before adding it to the crockpot creates a richer flavor and helps reduce excess moisture in your stew.
- Add Less Liquid Initially: Since crockpots don’t allow much evaporation, start with less broth or water than you’d use for stovetop stews. You can always add more later if needed.
- Toss Beef in Flour: Before browning, coat beef cubes lightly in flour. This not only helps with browning but also thickens the sauce as it cooks.
Crockpot Beef Stew Thickening FAQ

Most thickeners (like cornstarch, flour, or arrowroot) are flavor-neutral when used in small amounts. Potato flakes and mashed veggies add a bit of extra flavor and heartiness, while beurre manié adds a touch of buttery richness.
Can I use gluten-free options?
Yes! Arrowroot powder, cornstarch, mashed vegetables, and potato flakes are all gluten-free ways to thicken beef stew.
