How Long to Pressure Cook Frozen Beef Roast Step by Step
You can pressure cook your frozen beef roast without thawing by seasoning it directly and placing it in the cooker with at least 1 cup of broth or liquid. Cooking frozen beef roast in a pressure cooker saves time and locks in flavors effectively.
Cook for about 20 minutes per pound—so a 2-pound roast takes around 40 minutes. Make sure the valve is sealed and check doneness with a meat thermometer, extending time if needed.
Let it rest before serving for juicy results. Keep going if you want to master flavor and perfect timing.
Preparing Your Frozen Beef Roast for Pressure Cooking

Before you start pressure cooking, you’ll want to prepare your frozen beef roast properly to guarantee even cooking and great flavor.
First, check your roast for any ice crystals or frost. If there’s excessive frost, rinse it briefly under cold water to remove it, then pat dry with paper towels. This helps prevent excess moisture in the cooker.
Next, season your roast well. Even frozen, you can sprinkle salt, pepper, and your favorite herbs or spices directly onto the surface. If you have time, you can also add a dry rub. Avoid thawing the roast beforehand; pressure cooking is designed to handle frozen meat safely.
Finally, gather any aromatics or vegetables you plan to cook with the roast so you’re ready to assemble everything efficiently.
Setting Up the Pressure Cooker Correctly

When you set up your pressure cooker, make sure to add enough liquid to create the steam necessary for proper cooking. Usually, at least one cup of broth, water, or another flavorful liquid is needed. Place the frozen beef roast on the trivet or directly in the liquid to prevent burning.
Secure the lid properly, ensuring the pressure valve is set to sealing. Double-check that all seals and vents are clean and functioning to avoid pressure issues.
| Step | Action | Tip |
|---|---|---|
| 1 | Add liquid | Use broth for extra flavor |
| 2 | Insert roast | Use a trivet to avoid sticking |
| 3 | Secure lid | Ensure valve is set to seal |
| 4 | Check seals and vents | Clean to maintain pressure |
Recommended Cooking Times for Different Roast Sizes

Although cooking times can vary slightly depending on your pressure cooker model, you should generally plan for about 20 minutes per pound of frozen beef roast.
Cooking times vary, but plan on about 20 minutes per pound for frozen beef roast in a pressure cooker.
For a 2-pound roast, set the timer for roughly 40 minutes, while a 3-pound roast will need about 60 minutes.
If you’re cooking a larger 4 to 5-pound roast, expect it to take between 80 and 100 minutes.
Smaller roasts under 2 pounds may cook slightly faster, but sticking to the 20 minutes per pound rule guarantees even cooking.
Remember, these times are for frozen roasts; thawed roasts will require less time.
Adjust the cooking duration based on your roast’s size to get tender, juicy results every time.
How to Check for Doneness and Adjust Cooking Time
Knowing the recommended cooking times gives you a solid starting point, but checking for doneness guarantees your beef roast reaches the perfect tenderness. Use a meat thermometer to check the internal temperature. Aim for 145°F for medium-rare, 160°F for medium, or 170°F for well-done.
Insert the thermometer into the thickest part, avoiding bone or fat. If the roast isn’t quite done, seal the pressure cooker and cook in 5-10 minute increments, then check again. Keep in mind that frozen roasts might need extra time compared to thawed ones.
Also, let the roast rest for at least 10 minutes after pressure cooking. It continues to cook slightly, and juices redistribute, improving texture. Adjust cooking times based on these checks to get your roast just right every time.
Tips for Enhancing Flavor and Moisture During Cooking
To boost flavor and keep your beef roast juicy, you’ll want to incorporate a few key techniques before and during pressure cooking. Start by seasoning the roast generously with salt, pepper, and your favorite herbs or spices.
Searing the roast in a hot pan before pressure cooking locks in flavor and adds a rich crust.
Add aromatic vegetables like onions, garlic, and carrots to the pot for extra depth.
Pour in a flavorful liquid such as beef broth, wine, or a combination to maintain moisture and create a tasty sauce.
Avoid overfilling the pot with liquid; just enough to generate steam.
Finally, let the roast rest briefly after cooking to redistribute juices, ensuring every bite stays tender and flavorful.
