    ➕ Costco Lasagna Reviews

    Costco offers several lasagna options in the frozen foods and prepared foods sections. The frozen Costco Italian beef and sausage lasagna comes in a 2-pack that weighs a total of 6 lbs. The frozen Costco beef lasagna comes in a 6 lb 2-pack as well. (Perfect for potlucks or large gatherings!)

    Costco lasagnas

    Kirkland Signature is known for its high-quality products, and the frozen lasagnas are no exception. Both flavors of frozen lasagna have a rich and hearty flavor, with (almost!) a homemade taste. The meaty sauce, layers of pasta, and cheese blend create a satisfying and classic meal that wins on value and convenience.

    In the US, you can find the Costco ravioli lasagna in the prepared foods section. This item is refrigerated (not frozen), and it uses raviolis in place of the lasagna noodles of traditional lasagna. Check out my post on how long to bake lasagna at 350 if you’d like cooking instructions for this product.

    Depending on what your local Costco carries, you may also find other types of Costco lasagna. For example, my Costco used to carry Rana beef and short rib lasagna, but it appears to be discontinued. You can find freeze-dried #10 cans of Costco Mountain House lasagna with meat sauce at Costco online.

    How to Reheat Costco Lasagna

    A whole Costco lasagna won’t fit in most air fryers, and it’s impractical to cut off frozen pieces of lasagna to cook it. However, you can reheat pieces of lasagna in the air fryer (or microwave).

    Air fryer: Preheat air fryer basket to 350F (177C) for 5 minutes. Place the lasagna in an oven-safe baking dish, cover the lasagna with foil, and air fry for 15-20 minutes.

    Microwave (best method): Reheat Costco lasagna on a microwave-safe plate for 1-2 minutes on high.

    FAQs

    Which lasagna is best at Costco?

    According to our taste test, the best frozen lasagna Costco has to offer is the Costco Italian sausage and beef lasagna. It gives you all the great flavor of their beef lasagna, along with the richness of Italian sausage. The Costco sausage lasagna is a little less expensive and a bit higher in calories than the beef lasagna.

    Do you have to thaw Costco lasagna before cooking?

    No, you do not have to thaw Costco frozen lasagnas before cooking. The packaging recommends cooking these Costco products from frozen.

    How many people will a Costco lasagna feed?

    A package of Costco frozen lasagna will generously feed 12 people if you include some side dishes. Each package contains two 3 lb lasagnas, and each lasagna provides 6 adult-sized servings.

    Is Costco lasagna precooked?

    Costco lasagnas are partially precooked. The meat in the lasagnas may be fully or partially cooked, and the pasta is cooked. However, the cheese topping the frozen lasagnas is not cooked, and hasn’t melted yet. (That’s your job at home!)

    Is Costco lasagna vegetarian?

    Kirkland Signature frozen lasagna and the Costco ravioli lasagna are not vegetarian. Occasionally, you may find packages of frozen Amy’s lasagna at Costco that are vegetarian options.

    Notes

    💭 Expert Tips from a Dietitian

    This is a level 3 recipe (weight maintenance and active lifestyles). Costco lasagnas are an ultra-processed food and do not fit most of the special diets (low carb, vegan, gluten-free, low sodium, etc.). That said, they’re a quick option that feeds a crowd and satisfies many picky eaters. You can round out the meal by adding a large portion of non-starchy veggies (such as side salads) for more fiber and phytonutrients.
