In the following sections, we’ll delve into the essentials you need to know before placing that frozen roast in your Instant Pot, setting you up for success every time.

How to Cook Frozen Roast in an Instant Pot

Cooking a frozen roast in an Instant Pot is a convenient way to save time without sacrificing flavor or tenderness. The pressure cooking function allows the roast to cook evenly and thoroughly despite being frozen solid. To ensure the best results, follow these key steps:

Start by placing the frozen roast directly into the Instant Pot’s inner pot. There is no need to thaw the meat beforehand, which is one of the Instant Pot’s major advantages. Add a cup of liquid such as beef broth, water, or a marinade to generate the steam necessary for pressure cooking. Avoid filling beyond the maximum fill line.

Next, season the roast. Since the meat is frozen, dry rubs or salt may not adhere properly at this stage. Instead, add seasoning to the cooking liquid or plan to season immediately after cooking. You can also add aromatics like onions, garlic, or herbs in the pot to infuse flavor during the cooking process.

Use the “Manual” or “Pressure Cook” mode, setting the time according to the weight and cut of the roast. Typically, frozen roasts need about 50% longer cooking time than thawed ones. For example, a 3-pound frozen roast would require around 90 minutes under high pressure.

After the cooking cycle completes, allow the pressure to release naturally for at least 15 minutes before performing a quick release. This helps the meat retain juices and finish cooking evenly.

Finally, check the internal temperature to ensure food safety. If the roast is not yet tender or cooked through, you can reseal the pot and cook for additional increments of 10-15 minutes under pressure.

Pressure Cooking Times for Frozen Roast Cuts

Cooking times vary based on the size and type of roast. The following table provides recommended pressure cooking durations for common frozen roast cuts in an Instant Pot. Times include a 50% increase over thawed roast recommendations to account for the frozen state.

Cut of Roast Weight Pressure Cooking Time (Frozen)
Chuck Roast 2 to 3 lbs 75 to 90 minutes
Rump Roast 3 to 4 lbs 90 to 110 minutes
Round Roast 2 to 3 lbs 70 to 85 minutes
Brisket 3 to 4 lbs 90 to 105 minutes

Tips for Best Results When Cooking Frozen Roast

  • Use Enough Liquid: Pressure cooking requires liquid to create steam; ensure you add at least 1 cup of broth or water.
  • Avoid Overfilling: The Instant Pot should not be filled beyond the halfway mark when cooking roasts to allow for pressure buildup.
  • Natural Pressure Release: Allowing a natural release helps keep the roast moist and tender.
  • Sear After Cooking: For a crisp exterior, consider searing the roast in the Instant Pot using the sauté function once it is cooked and removed from the pot.
