Quick Answers

f you don’t have one yet, here are Instant Pot models that handle frozen roasts reliably (size matters for 2–5 lb cuts). [Check Instant Pot options on Amazon]

How long do you cook a frozen roast in the Instant Pot

Plan about 30 minutes per pound on High Pressure plus 15 to 20 minutes natural release. Check with a fork and add 10 to 15 more minutes if needed. This timing helps collagen soften so the roast turns tender.

Do you need to thaw the roast first

No. Place the frozen roast over broth and aromatics, pressure cook using the time chart, then natural release. Season again after cooking if needed and thicken the juices into gravy right in the pot.

When should I add potatoes and carrots

After the roast cooks. Pressure cook vegetables in the hot juices for 3 to 5 minutes, then quick release. This method prevents mushy textures and keeps flavors bright.

Why Pressure Cooking a Frozen Roast Works

Moist heat under pressure breaks down connective tissue quickly. Cuts like chuck and shoulder respond best because collagen turns to gelatin, which creates juicy and shreddable meat. A full natural release lets fibers relax so the roast stays tender and sliceable.

Why this matters: Skipping the natural release often leads to tougher meat. Let the pot drop pressure on its own for best texture.

Frozen Roast in Instant Pot Time Guide

Use this as a starting point and always check tenderness.

2 lb: 60 minutes High Pressure plus 15 to 20 minutes natural release
3 lb: 90 minutes High Pressure plus 15 to 20 minutes natural release
4 lb: 120 minutes High Pressure plus 15 to 20 minutes natural release
5 lb: 150 minutes High Pressure plus 15 to 20 minutes natural release

Rule of thumb: frozen roasts need about 30 minutes per pound. Thawed roasts usually need about 20 minutes per pound. For storage and leftovers safety, consult USDA FSIS leftovers guidance.

Cook a frozen chuck roast for about 30 minutes per pound on High Pressure, then let pressure drop naturally for 15 to 20 minutes. If it is not fork tender, add 10 to 15 minutes more. Add root vegetables after the meat cooks to avoid overcooking.

How to Cook Frozen Roast in the Instant Pot

onion wedges, garlic, and broth inside a pressure cooker insert — Start with broth, onion, and garlic to build flavor

frozen chuck cut placed over onions in stainless steel insert — Season the exposed surface and set High Pressure

Build flavor: Add broth, onion, and garlic to the pot. Place the frozen roast on top. Season any exposed surface with salt, pepper, paprika, and thyme.
Pressure cook: Seal and cook on High Pressure using the time chart.

Natural release: Let the pressure drop on its own for 15 to 20 minutes; quick release any remaining steam.
Check tenderness: A fork should slide in easily. If not, cook 10 to 15 minutes more and repeat a short natural release.
Make gravy: Remove the roast to rest. Set Sauté. Whisk 2 tablespoons cornstarch with 2 tablespoons cold water, then whisk into the hot juices until glossy.
Optional browning: Briefly sear thick slices on Sauté or broil 2 to 3 minutes for deeper color.

Troubleshooting:
Still firm: add 10 to 15 minutes and repeat a short natural release.
Thin juices: reduce on Sauté or add a little more slurry.
Burn warning: ensure at least 1 to 1.5 cups liquid and scrape the bottom before sealing.

Tip: A raised trivet helps prevent scorching and improves liquid circulation. [Get an Instant Pot trivet on Amazon]

Potatoes and Carrots Timing

To keep vegetables intact, cook them after the meat.

Add 1 to 1.5 pounds baby potatoes and 3 to 4 sliced carrots to the hot juices

Instant Pot Frozen Roast FAQ

How long to cook a 2, 3, 4, or 5 pound frozen roast in the Instant Pot

Use about 30 minutes per pound on High Pressure. That is roughly 60, 90, 120, or 150 minutes. After cooking, let pressure drop naturally for 15 to 20 minutes and check tenderness. If a fork does not slide in easily, add 10 to 15 more minutes and test again.

Can I cook a pot roast from frozen without thawing

Yes. Add broth and aromatics, place the frozen roast on top, and pressure cook using the time chart. Natural release keeps fibers relaxed. Season to taste at the end and turn the cooking liquid into gravy for moisture and flavor.

Why is my pot roast still tough

It needs more time or a full natural release. Collagen softens with both heat and time. Use a cut like chuck or shoulder, rest the roast before slicing, and slice against the grain. If needed, return to pressure for 10 to 15 minutes and test again.

Can I add vegetables at the start

You can, but they often overcook. For the best texture, cook the roast first. Then pressure cook potatoes and carrots for 3 to 5 minutes in the hot juices and quick release. Season and serve immediately.

Do I need to sear the roast

No. Starting from frozen makes searing difficult up front. For browned edges, briefly sear slices after cooking using Sauté or a short broil. This adds color while keeping the roast tender.
