Costco’s lasagna is such a fantastic choice for a budget-friendly crowd-pleaser! While it may not quite reach the mouthwatering heights of homemade lasagna, we genuinely believe it’s the top pick among store-bought frozen options. When you’re in a time crunch, Costco’s lasagna is a superb alternative to consider.
We picked up the Kirkland Italian sausage and beef lasagna, and we’re delighted with our find! You get two three-pound trays, which means a generous total of twelve satisfying servings. And the best part? It only set us back $16.99 for both packages, working out to less than $1.50 per serving. What a tasty deal!
I found the cooking directions on the back of the Kirkland lasagna package super handy! To make sure it’s just right in my oven, I decided to put it to the test. After about 45 minutes of cooking, I stuck a probe into the lasagna. This way I would know exactly when it was ready.
Let’s kick off our lasagna-making adventure with a preheat! If you’re using a regular oven, set it to a toasty 375°F. For those with a convection oven, a slightly lower 350°F will do the trick, and you’ll follow the same cooking time.
Once your oven reaches the right temperature, it’s time to unveil your frozen Costco lasagna. The good news is that this version is designed to go straight from the freezer to the oven, so no need to thaw it beforehand. Take off the cardboard cover and set the tray on a baking sheet. You’ll want to make a small slit in the center of the film cover on top of the tray. If, by any chance, you’ve removed the plastic film entirely, don’t fret! Just cover the lasagna with aluminum foil. This will let the steam escape and prevent the top layer from getting too crispy.
Now, pop the baking sheet onto the middle oven rack and let the lasagna work its magic for a total of fifty-five minutes. Here’s a little trick: at the forty-five-minute mark, I like to remove the plastic wrap to give the top layer that beautiful golden brown finish. The internal temperature in the center usually reaches around 145°F at this point.
Keep a close eye on it, and once it reaches a safe 165°F using an instant-read thermometer, you’re in the home stretch. In my oven, it hits the mark at around sixty minutes, but you might find that perfect look you like on top around sixty-five minutes of total cooking time.
I must say, it’s a great idea to let the lasagna sit for ten to fifteen minutes before slicing into it. It allows everything to settle, but I confess, we’re usually too eager to dig in right away! Enjoy your delicious meal!
When it comes to flavor, this lasagna is a real treat! It boasts a delightful blend of beef, sausages, marinara sauce, creamy ricotta cheese, and the best part – those lasagna noodles stay perfectly al dente. If you were to serve it up in a baking dish, some folks might just mistake it for a homemade masterpiece.
Now, when we look at it from an ingredient and health perspective, it’s not exactly a healthy food, but it’s a better choice compared to most frozen options. In each generous serving, you’ll find 22 grams of total fat, 890 milligrams of sodium, 3 grams of dietary fiber, 7 grams of sugars, a hearty 23 grams of protein, and a total of 410 calories.
If you find yourself with some lasagna leftovers, don’t worry! Just tuck them into an airtight container and pop them in the fridge. When it’s time to enjoy them again, the microwave is your best friend. Simply place the lasagna in a covered container and heat it up for thirty seconds at a time until it’s nice and hot. By the way, I’ve got a little secret for you – the second-day lasagna is often even better than the first. Bon appétit!
