What Kinds of Lasagna Does Costco Offer in 2025?
Let’s start with variety—because Costco doesn’t just stick to one recipe. Here’s what you can expect to find in the freezer aisle:
1. Kirkland Signature Beef Lasagna
This is the classic everyone knows. Made with layers of pasta, seasoned ground beef, rich tomato sauce, and a blend of mozzarella and ricotta cheeses, it’s hearty, familiar, and crowd-pleasing.
2. Kirkland Signature Italian Sausage & Beef Lasagna
For those who like a little more zip, this version includes both Italian sausage and beef. It’s bolder in flavor and packs an extra punch in the seasoning department.
3. White Chicken & Pesto Lasagna (Limited Availability)
Looking for something a little different? Some stores carry a white lasagna variation with chicken and pesto. It’s lighter in flavor but still rich and filling—great for those who want a twist on the traditional.
4. Rana Brand Lasagnas (Select Warehouses)
Some locations carry imported or specialty lasagnas from Rana, often including premium meat cuts like short ribs or vegetable-based versions. These rotate throughout the year.
How Much Does Costco Lasagna Cost in 2025?
Prices vary slightly by region, but as of 2025, here’s a general idea:
- Kirkland Beef Lasagna (2-pack, 3 lbs each): around $16.99
- Sausage & Beef Lasagna (2-pack, 3 lbs each): around $17.99
- Chicken & Pesto (3 lbs single tray): approx. $13.49
Each tray typically feeds about 5–6 people, making this one of the best cost-per-serving deals in the frozen aisle.
Cooking Instructions: Easy & Flexible
You don’t need to thaw Costco lasagna—just pop it in the oven or microwave.
Oven Method (Best for Flavor)
- Preheat to 375°F.
- Remove packaging and place lasagna in an oven-safe dish.
- Cover with foil and bake for 55 minutes.
- Uncover and bake for 10–15 more minutes.
- Let it sit for 5 minutes before serving.
Microwave Method (Faster)
- Slice a portion and place in a microwave-safe dish.
- Cover loosely.
- Microwave on high for 8–12 minutes.
- Let it rest briefly before eating.
The oven method gives you the perfect cheesy top, but microwave works well when you’re short on time.
How Does It Taste?
Costco lasagna doesn’t disappoint. The Kirkland versions are rich, cheesy, and well-seasoned. The beef version is a traditional comfort food classic, while the sausage blend has a nice, mild kick. The chicken & pesto version is lighter but still creamy.
You get solid texture, balanced flavor, and satisfying layers—definitely a step above your average frozen lasagna.
The taste holds up just as well as favorites like the Costco chicken bake.
