How To Cook Frozen Costco Lasagna?

Cooking frozen lasagna should be a breeze, and Costco ensures it is. The straightforward cooking instructions provide a hassle-free experience. Here’s how I do it –

Oven Baking

  • Preheat your oven to 375°F (190°C).
  • Remove the plastic film cover and place the lasagna on a baking sheet.
  • Slide it onto the middle oven rack for about 55 minutes.
  • Use a thermometer to check that the internal temperature of frozen lasagna reaches at least 165°F (74°C).

Microwave Magic

  • When I’m short on time, I opt for the microwave. First, I slit the film cover.
  • Cook the lasagna on high for 14 minutes, ensuring the film cover stays on.
  • A couple of minutes of waiting, and it’s ready to enjoy.

Air Fryer Adventure

  • Sometimes, I like to experiment with my trusty air fryer. I place the lasagna in the air fryer basket.
  • Cooking at 375°F (190°C) for about 14 minutes or until the cheese is gloriously bubbling.

Pro tip – Check the lasagna a bit before the suggested time to ensure it doesn’t get overcooked. You want it bubbling, cheesy, and just right.

Taste Test – Beyond Delicious

Now, let’s get to the heart of the matter – the taste. Both varieties of Kirkland Signature lasagna left a lasting impression –

Kirkland Italian Sausage and Beef Lasagna

This indulgent dish boasts layers of rich meat sauce, tender lasagna noodles, and a perfect blend of mozzarella and ricotta cheese. The Italian sausage adds a delightful kick, making every bite a savory adventure.

Kirkland Beef Lasagna

The beef lasagna, while simpler in ingredients, doesn’t skimp on flavor. It’s hearty, meaty, and a true crowd-pleaser. The generous use of whole milk mozzarella and ricotta cheese adds a creamy, comforting element.

Costco occasionally introduces seasonal lasagna options, so keep an eye out for unique flavors.

Kirkland’s Lasagna Options
