Anything your traditional oven can do, the Anova Precision Oven can do better — and faster. Yes, that even includes frozen dinners like lasagna, casseroles, and other dense entrées.
As a general guideline, most frozen dinners can be cooked in the Anova Precision Oven at 350ºF/177ºC with 100% steam. The cook time will depend on the size, density, and contents of your dish but single-serve frozen dinners usually take about 25 to 30 minutes while larger, family-style casseroles and lasagnas need closer to an hour.
While you’re figuring out the proper cook times for your favorite frozen dinners, use the included Food Probe to determine how long each dish takes to reach an internal temperature of 165ºF/74ºC. You probably won’t be able to get the probe into a frozen-solid lasagna (and please don’t hurt yourself or the probe trying!) so plan to carefully insert it into the center of your meal about 15 or 20 minutes into the cook. And make sure you’re really in the center, because if you take the probe all the way to the bottom of the dish, you’ll get a higher reading and take your dinner out of the oven too soon.
This method also works for homemade casseroles that have been made ahead and frozen.
