Choosing the Right Roast
Opt for a well-marbled roast with ample fat distribution for the most tender, flavorful results when cooked from frozen. Here are great options:

Chuck roast – The heavily marbled meat has tons of beefy flavor. It’s very forgiving and ideal for pot roasts.
-
Rib roast – With beautiful marbling and fat cap, rib roasts stay succulent and deliver rich taste.
-
Rump roast – Leaner than other cuts but delivers good flavor. Sliced thin, it makes nice sandwiches.
-
Sirloin tip roast – Budget-friendly choice for smaller households. Cook sliced for more tender meat.
-
Tri-tip roast -fibers slice beautifully when cooked correctly. The tapered shape cooks evenly from frozen.
Aim for a 3-5 pound roast, ideally frozen for less than 4-6 months for best results. Now let’s prep it for the oven or slow cooker.
Prepping and Seasoning the Roast
Follow these simple steps before cooking:
-
Trim – Trim off any dried or discolored portions from the frozen roast. This prevents a bitter taste.
-
Pat dry – Patting the roast with paper towels removes lingering ice crystals and helps seasoning adhere.
-
Season generously – Coat all sides with salt, pepper and any other seasonings like garlic, herbs or spices.
-
Drizzle with oil – Rub a light coating of olive oil or avocado oil over the roast to help retain moisture.
Now the roast is ready for a slow cooker or oven. Let’s look at oven roasting first.
How to Cook a Roast from Frozen in the Oven
Roasting in the oven at a low temp delivers incredibly tender, fall-apart meat with mouthwatering aroma throughout your home. Here’s how:
-
Prep [as shown above]

Preheat oven to 275F – Use a lower temp than for a thawed roast. This allows time for the inside to cook through.
-
Place roast on a wire rack in a roasting pan – The rack elevates it to promote air circulation for even cooking.
-
Cook for approximately 1 hour per pound – For a 4 pound roast, cook for about 4 hours. Use an instant read thermometer to check doneness.
-
Rest 10-15 minutes before slicing – Letting it rest allows juices to redistribute so they don’t run out when carved.
The low, slow oven method results in the perfect medium-rare roast. For well-done, increase temperature to 300F and add cooking time as needed.
Next, let’s look at how to make an insanely delicious crockpot roast from frozen.
