The Costco Deli Mac and Cheese is one of the most popular prepared meals in the Kirkland Signature lineup. Sold fresh in the refrigerated section, this hefty tray of baked pasta has earned a reputation for being rich, satisfying, and easy to prepare.
But is it really worth the $15 price tag—and the calories? In this in-depth review, we’ll break down the ingredients, taste, cooking method, value, and nutrition so you can decide if it’s worth adding to your cart.
What You Get: First Impressions
You’ll find the Kirkland Signature Mac and Cheese in the deli section, alongside other Costco prepared meals like lasagna, chicken alfredo, and pot pie. It comes in an aluminum baking tray, sealed with a clear lid and a label that includes heating instructions and ingredients.
- Pasta: Penne pasta, fully cooked and ready to bake.
- Sauce: A creamy white Alfredo-style base made with Romano and Parmesan cheeses.
- Topping: A generous layer of shredded orange cheddar cheese.
This isn’t your average boxed mac and cheese. The sauce is rich and thick, and the portion size is large enough to feed a crowd.
Pricing and Value
- Price per Pound: $3.99
- Typical Tray Weight: Around 3.8 to 4.2 lbs
- Total Cost Example: $15.20 for 3.81 lbs
At under $4 per pound, this mac and cheese is priced very competitively—especially for a prepared meal with real cheese and a decent ingredient list. It’s hard to match the convenience and quantity for the price.
How to Cook It
Cooking the Costco mac and cheese is straightforward. Just follow the instructions on the package:
- Preheat oven to 400°F (204°C).
- Keep the mac and cheese in the aluminum pan and cover it with foil.
- Place the tray on a baking sheet to catch any overflow.
- Bake for 40–60 minutes, until it reaches an internal temperature of 165°F (use a thermometer for accuracy).
- For a browned, crispy topping, remove the foil during the last 10 minutes.
Optional: Let it rest for 5 minutes before serving to allow the sauce to thicken slightly.
Taste Test: Flavor and Texture
This is where Costco’s mac and cheese really stands out. The sauce is incredibly creamy with a blend of Romano and Parmesan that gives it more depth than a typical cheddar-based version. The cheddar topping adds saltiness and a crispy crust when baked properly.
- Sauce: Rich, cheesy, and savory with subtle tang from the Parmesan.
- Pasta: Penne holds its shape and texture well; not mushy even after baking.
- Topping: Golden brown and slightly crisp on the edges, adding texture contrast.
The dish is indulgent and satisfying—a true comfort food experience.
