3-5 days

How long does homemade lasagna last in the freezer? Properly stored, it will maintain best quality for about 2 to 3 months, but will remain safe beyond that time. The freezer time shown is for best quality only – cooked lasagna that has been kept constantly frozen at 0°F will keep safe indefinitely.

Store a full or portioned lasagna in the freezer for up to three months.

A: If you assemble and bake the lasagna ahead of time, you shouldn’t keep it longer than three days in the refrigerator. If you need to keep it longer, it would be better to freeze it and reheat it. If you just need to make it a day ahead, you could refrigerate it before baking it.

If you’re craving homemade lasagna but don’t have the time, Costco’s frozen lasagna is the next best thing. It takes the top spot for best-frozen lasagna, according to the San Jose Mercury News, offering a good balance of cheese to sauce ratio and homemade Italian flavor.

Preheat the oven to 375 degrees Fahrenheit. Cut a 2-inch slit in the film covering the lasagna. Put the tray on a cookie sheet on the middle oven rack. Cook for 55 minutes, and then take away the film cover.

Conventional Oven:

1. Preheat oven to 375°F.
2. Separate twin pack. Cut a 2″ slit in film cover. Place tray on cookie sheet on middle oven rack.
3. Cook 55 minutes. Remove film cover and continue cooking for 10 minutes to brown cheese.
4. Remove from oven and let stand 5 minutes.

There is no need to thaw it first. In a conventional oven, it will take approximately 90 minutes to fully bake a 38-ounce frozen lasagna, and just 20 additional minutes to bake a 96-ounce family-sized casserole.

Vine-ripened tomatoes. Whole milk mozzarella cheese. No artificial ingredients, only minimally processed. Keep frozen.

So overall, I give Costco Kirkland Beef Lasagna an A++ for overall taste and texture. It took two hours to bake, which was very long but well worth the wait. The Kirkland Frozen Beef Lasagna comes in a foil tray with a foil cover, so it is that easy. It is not microwaveable at all.

It Tastes Great With all of it’s layers of saucy meat and cheese, lasagna tends to be a hearty well rounded meal which works to keep everyone full. Costco’s version is a wonderful combination of beef and Italian sausage making it better than most other frozen lasagnas.

1. Preheat the oven to 375 degrees Fahrenheit.
2. Cut a 2-inch slit in the film covering the lasagna.
