Costco lasagna is a very economical crowd-pleaser. It is better than most frozen lasagna that you can buy in your grocery store, we actually think that it is the best-frozen lasagna on the market. Whereas it’s not as good as my homemade lasagna Costco’s lasagna is a
We bought the Kirkland Italian sausage and beef lasagna. It comes in two three-pound trays for a total of twelve nice-sized servings. The cost for the two packages was $16.99 or less than $1.50 per serving.
The back of the Kirkland lasagna package has cooking directions on it. To test the cooking times in my oven after cooking for 45 minutes I stuck a probe into the lasagna.
The first thing we need to do is preheat our traditional oven to 375F. If your using a convection oven preheat to 350F and follow the same cooking time.
When the oven is preheated remove your frozen lasagna from the freezer. Costco’s version has been formulated to be cooked from a frozen state, so do not thaw before cooking. Remove the cardboard cover and place the tray on a baking sheet. Cut a slit into the center of the film cover on top of the try. If by accident you removed the plastic film you can cover the lasagna with aluminum foil. This will allow steam to escape and keep the top layer from burning. Place the baking sheet onto the middle oven rack and cook for fifty-five minutes.
Note: At forty-five minutes I removed the plastic wrap to allow the top layer to brown a little more. The internal temperature in the middle at this time was 145F.
Cook uncovered or until the top looks good to you and the internal temperature reaches 165F with an instant-read thermometer. Mine reached 165F at sixty minutes of cooking time. But the top look just the way I like it at sixty-five minutes total cook time.
I do recommend letting the lasagna sit for ten to fifteen minutes before cutting into it but we never wait.
Flavor-wise the lasagna has a wonderful combination of beef, sausages, marinara sauce, ricotta cheese, and best of all the lasagna noodles are not mushy. If you were to serve this in a baking dish some folks would think you made it from scratch.
Ingredient/health wise it’s not healthy but better than most frozen foods. Each good size serving contains 22 grams of total fat, 890 grams of sodium, 3 grams of dietary fiber 7 grams of sugars, 23 grams of protein, and 410 calories.
If you have some leftover lasagna place it into the fridge in an airtight container. The best way to reheat leftovers is by using the microwave. Place the lasagna into a covered container and microwave thirty seconds at a time until it is hot. BTW: the second-day lasagna is better than the first day.
