To thicken sauce in a pressure cooker, the crucial first step is always to release pressure and open the lid before adding any thickening agents. Common methods include creating a slurry with cornstarch or flour mixed with cold water, stirring it into the hot sauce, and simmering until desired consistency. Alternatively, simply simmering the sauce with the lid off allows for natural reduction, concentrating flavors and thickening the sauce effectively.
Unlock the secret how to thicken sauce in pressure cooker
Ever finished cooking a delicious meal in your pressure cooker, only to find your sauce a bit too thin or watery? It’s a super common experience, and honestly, it used to frustrate me too! The pressure cooker is fantastic for speed, but that lack of evaporation can leave us with a thinner sauce than we’d like. But don’t worry, I’ve got you covered. You absolutely can thicken sauce in pressure cooker *after* the cooking cycle, and it’s usually just a quick extra step that makes all the difference.
The good news is, learning how to thicken sauce in pressure cooker is incredibly simple once you know the tricks. There’s no need to transfer your food to another pot or compromise on flavor. We’re going to use the magic of your pressure cooker’s sauté function to get that perfect consistency, just like a pro. Let’s dive into the best ways to tackle this common kitchen dilemma!
So, what’s the best way to thicken sauce in pressure cooker after it’s done?

Ah, the million-dollar question! The key to successfully thickening your sauce after pressure cooking lies in understanding that a pressure cooker traps moisture, preventing the natural reduction you’d get on a stovetop. But fear not, your appliance often has a secret weapon: the “Sauté” or “Browning” function. This is your best friend when you need to thicken sauce in pressure cooker.
Here’s my go-to approach, shared with a few personal tips and tricks:
1. The Simple Simmer (Sauté Function):
This is usually my first step if the sauce is just a little bit watery. After the pressure has naturally released or you’ve quick-released it, carefully remove the lid. Switch your pressure cooker to the “Sauté” or “Browning” setting. This turns the bottom heating element on, just like a regular pot on the stove. Let your sauce gently simmer, stirring occasionally, until it reaches your desired thickness. The steam will escape, and the sauce will reduce. For things like stews or chili, this method works wonderfully. I often find 5-10 minutes is enough for a noticeable change, but sometimes it takes a bit longer, so be patient!
2. The Starch Slurry Method (My Personal Favorite for Quick Results):
If simmering isn’t cutting it, or you’re in a hurry, a starch slurry is your best bet. This is how I achieve beautifully thick sauces for gravies, curries, or even creamy pasta dishes right in the pressure cooker. Here’s how I do it:
- Choose your starch: Cornstarch is my usual go-to for a clear, glossy finish. Flour works too for a more opaque, gravy-like sauce. You can also use arrowroot powder or tapioca starch.
- Mix it cold: This is CRUCIAL. In a separate small bowl, whisk together 1 tablespoon of your chosen starch with 2-3 tablespoons of cold water or cold broth. Mix it until there are absolutely no lumps. I learned the hard way that adding dry starch directly to hot liquid creates instant lumps!
- Add to the pot: With your pressure cooker still on the “Sauté” setting (or bring it to a simmer on low), slowly pour the slurry into your sauce while continuously stirring.
- Stir and thicken: Keep stirring for 1-2 minutes. You’ll literally watch the sauce thicken before your eyes. If it’s still not thick enough, repeat the process with another small slurry. Remember, it’s always easier to add more than to thin it out!
I recently made a chicken stew, and the sauce was too thin. A quick cornstarch slurry, added right into the pot while on “Sauté,” transformed it into a rich, velvety consistency in minutes. It felt like magic!
3. Healthy Thickeners (My Sneaky Trick):
Sometimes, if I’m making a hearty soup or stew that already has potatoes, beans, or lentils, I’ll scoop out about half a cup of the cooked vegetables, mash them with a fork, and stir them back into the sauce. This adds body and nutrients without needing extra starches. It’s a fantastic way to thicken sauce in pressure cooker while boosting flavor and texture naturally. A friend once showed me this trick, and I’ve been using it ever since!
4. Enriching with Cream/Cheese (For Specific Dishes):
For creamy sauces, like for pasta or a rich soup, adding a splash of heavy cream, coconut milk, or even some grated Parmesan cheese while simmering can add wonderful body and flavor. This isn’t just about how to thicken sauce in pressure cooker; it’s about making it even more delicious! Just remember to add these at the very end, off pressure, to prevent curdling.
Don’t fret if your sauce isn’t perfect right out of the cooker – it’s a common pressure cooker quirk! With these simple steps, you’ll master how to thicken sauce in pressure cooker in no time. Always taste and adjust, and most importantly, enjoy your perfectly sauced meal!
