Beet size is the single biggest variable in how long they take under pressure, and a golf-ball beet next to a fist-size one on the same rack will not finish at the same time. This chart breaks the timing down by size, whether the beets are left whole or halved, and whether you release naturally or quick release, so you can pick a number that actually matches what’s in your basket.
Quick answer: Small beets (1.5 to 2 inches) generally need 15 to 20 minutes at high pressure, medium (2 to 3 inches) 20 to 25 minutes, large (3 to 4 inches) 25 to 32 minutes, and extra-large (4-plus inches) 30 to 40 minutes. Halving cuts several minutes off any size. Always confirm with a fork or paring knife rather than trusting the clock alone.
| Beet Size | Approx. Diameter | Cut | High Pressure Time (short natural release, ~10 min, then vent) | High Pressure Time (immediate quick release) | Fork-Test Check |
|---|---|---|---|---|---|
| Small (S) | 1.5 to 2 in | Whole | 15 to 18 min | 18 to 20 min | Paring knife slides to center with almost no resistance |
| Small (S) | 1.5 to 2 in | Halved | 10 to 12 min | 12 to 14 min | Fork tines pierce flesh easily, no crunch at the core |
| Medium (M) | 2 to 3 in | Whole | 20 to 22 min | 22 to 25 min | Knife meets slight resistance at dead center only |
| Medium (M) | 2 to 3 in | Halved | 14 to 16 min | 16 to 18 min | Flesh gives evenly from edge to cut face |
| Large (L) | 3 to 4 in | Whole | 25 to 28 min | 28 to 32 min | Push knife in slowly; any grittiness means more time |
| Large (L) | 3 to 4 in | Halved | 18 to 20 min | 20 to 22 min | Center of cut face yields under light fork pressure |
| Extra-Large (XL) | 4 in or more | Whole | 30 to 35 min | 35 to 40 min | Test at two points, stem end and root end |
| Extra-Large (XL) | 4 in or more | Halved or quartered | 22 to 25 min | 25 to 28 min | Fork slides through thickest wedge without stopping |
Instant Pot Beets Cook Time by Size, Explained
The chart above uses a standard trivet with about a cup of water in the pot, which is the common setup for steaming beets rather than boiling them directly. If you stack beets two or three layers deep instead of arranging them in a single layer, plan on adding a few minutes to whatever size range you land on, since crowding slows how evenly heat reaches the center of each beet.
Whole beets keep more color and nutrients in the flesh but take noticeably longer because the skin and outer flesh act as insulation. Halving exposes more surface area to steam, which is why halved beets in every size category finish 4 to 8 minutes faster than their whole counterparts. Quartering large or extra-large beets shaves off a bit more time on top of that, though it isn’t shown as its own row since the timing lands close to the halved XL range.
Why Two Time Columns
The short-natural-release column and the immediate-quick-release column aren’t the same test run at two speeds. Beets keep cooking gently while pressure drops naturally, so a pot that sits for about 10 minutes before you vent it delivers a bit more residual cooking than one you release the instant the timer beeps. That’s why the quick-release times in the chart run slightly longer: they’re set a few minutes higher to make up for the cooking you lose by venting right away.
What Changes the Number
- Size and shape irregularity: Beets from the same bunch can vary by half an inch or more. When in doubt, time for the largest beet in the batch and expect the smaller ones to be a touch softer, which is usually fine for beets since a slightly overcooked one is still edible and easy to peel.
- Starting temperature: Beets straight from the fridge take longer to come up to pressure and may need a minute or two more inside the pot than beets that sat at room temperature first.
- Altitude: Water boils at a lower temperature at elevation, and pressure cookers compensate less efficiently the higher you go. If you’re above roughly 3,000 feet, add cook time and check your appliance manual for its altitude adjustment guidance.
- Appliance model: Pressure cooking behavior varies by brand and even by model within the same brand, since pot size, sealing efficiency, and pressure-build speed differ. Treat every number here as a starting point and confirm doneness yourself rather than assuming your unit matches the chart exactly.
- Age of the beets: Beets that have been in storage for weeks tend to be denser and can need a few extra minutes compared to freshly harvested ones.
The Fork-Test: How to Actually Check Doneness
Beets don’t have a food safety minimum temperature the way poultry or ground meat do, since the concern with a root vegetable is texture, not pathogen risk. That means the clock is only a guide, and the fork or paring knife test is what actually tells you it’s done.
Let the pot finish releasing pressure, then lift the lid away from your face. Pick the largest beet and press a fork or the tip of a paring knife into the center. It should slide in with only the faintest resistance, similar to a cooked potato. If you feel any grittiness or hard core, reseal and pressure cook for another 3 to 5 minutes rather than guessing at a longer time from scratch. For a size comparison on a related root vegetable, the Instant Pot potatoes chart uses the same fork-test logic across size categories.
Natural vs Quick Release for Beets
Natural release is generally the gentler option for beets. Letting pressure drop on its own for 10 to 15 minutes, or fully naturally releasing, tends to produce more even texture edge to edge and makes the skins slip off more easily under running water afterward. Quick release is faster but can leave the outer inch slightly firmer than the core if the timer was set short, since the beet loses the benefit of that extra passive cooking window.
Either method works fine for everyday cooking. If you’re short on time, quick release with the slightly longer set times from the chart is a reasonable trade. If you have the extra 10 to 15 minutes and want easier peeling, natural release is worth it.
Common Mistakes
- Mixing sizes on one rack: Small and extra-large beets cooked together will never finish evenly. Sort by size first, or accept that the small ones will be softer than ideal.
- Skipping the water: Beets need liquid under the trivet to build steam pressure. Too little water can trigger a burn warning or an inaccurate cook cycle on some models.
- Peeling before cooking: Peeling raw beets bleeds color and nutrients into the cooking liquid and makes them mushier. Cook with skins on, then rub the skins off once they’re cool enough to handle.
- Not accounting for carryover: Beets continue softening slightly for a few minutes after release, especially with natural release. Pull them a touch before they feel perfectly done if you plan to serve them warm right away.
- Guessing weight instead of measuring diameter: Weight varies with shape and density. A quick diameter check with a ruler or by eye against a known size (a golf ball, a tennis ball, a fist) is more reliable for matching the chart.
FAQ
How long does it take to pressure cook beets in an Instant Pot?
It depends mainly on size. Small beets generally take 15 to 20 minutes, medium 20 to 25 minutes, large 25 to 32 minutes, and extra-large 30 to 40 minutes at high pressure, with halved beets running a few minutes shorter than whole ones in every category.
Do I need to peel beets before pressure cooking?
No. Cooking with the skin on is the standard approach, since it holds in color and nutrients and makes peeling easier afterward, when the skin rubs off under water rather than needing a peeler.
Can I stack multiple beets in the Instant Pot at once?
Yes, but a single layer on the trivet cooks most evenly. Stacking beets two or three deep is fine for a batch, just expect to add a few minutes to your set time and to fork-test more than one beet before assuming the whole batch is done.
Why are my Instant Pot beets still hard after cooking?
The most common reasons are an undersized cook time for the beet’s actual diameter, beets that were larger than expected, or a quick release that cut the cooking short. Reseal and pressure cook in 3 to 5 minute increments, checking with a fork each time, rather than starting the full cycle over.
Bottom Line
Match your set time to the largest beet in the pot, choose whole for color and texture or halved for speed, and treat natural release as the more forgiving option when you have the extra minutes. The chart gets you close, and the fork test closes the gap. A simple steamer basket or trivet insert makes it easier to keep beets elevated above the water for even steaming, and something like this steamer basket and trivet set is a low-cost way to set that up. Beet juice also stains hands and cutting boards fast, so a pair of reusable kitchen prep gloves is worth keeping nearby for the peeling step. If you’re building out a full pressure cooker rotation, the Instant Pot chickpeas no-soak chart covers a similarly size-and-timing-driven ingredient worth having on hand.
