Costco Mac And Cheese - Price, Cook Tips, + Flavor Hacks


Kirkland Signature Macaroni and Cheese at Costco

Costco sells 3.75 pound packages of Macaroni and Cheese for $3.49 a pound. The mac and cheese sells for approximately $13 and can be found in the prepared meals section of the warehouse near other items such as the garlic drumsticks, taco kit, and bulgogi beef.


Costco’s mac and cheese is made with a creamy alfredo sauce as well as with romano, parmesan, and shredded cheddar cheese.

Costco Sized

As expected, this mac and cheese from Costco is going to be Costco sized. 

I usually feel pretty confident about finishing most of Costco’s prepared meals because typically they are entrees, but this side dish of mac and cheese is going to be a challenge.


3.75 pounds of mac and cheese is quite a lot, and it seems this prepared meal is better suited for a party or a gathering rather than an individual or small family.

Costco Cost Comparison

Costco sells their mac and cheese for $3.49 a pound and each package costs about $13-$14. This seems to be a little pricey but is definitely still fair value. 

This is a massive side dish that can easily feed 8-10 people if not more!

Costco vs Sam's Club

Sam’s Club sells their macaroni and cheese for the same price at $3.48 a pound. I haven’t tried it and can’t speak for the quality, but 9 times out of 10, I will go with the Kirkland Signature product over the Member’s Mark item.

Costco Macaroni and Cheese Taste Test

I followed the instructions on the packaging and baked the mac and cheese for 400°F for about 45 minutes or so.


Great Looking Cheese

The mac and cheese came out looking beautiful with perfectly melted cheddar cheese on top.

I probably could have left the mac and cheese in the oven for a few more minutes to get a crispier layer of cheddar cheese, but the cheese I had was more than satisfactory.


Lacking in Flavor

The macaroni came out great, and there was plenty of cheese and creamy sauce in every bite, but unfortunately, the mac and cheese was quite bland. 

The ingredients are there, but for some inexplicable reason, the flavor isn’t. There is plenty of creaminess in the macaroni, but it just doesn’t do much for me.


I would have liked much more depth to the flavor as well as intensity. 

The dish is bland, and won’t turn anybody off, but also won’t wow anybody. It’s a very forgettable dish. 


I ate the Macaroni and Cheese with some super tender Tri-Tip

If I were to serve this at a party, I would need to modify the dish to boost the flavor significantly. I include a couple of serving suggestions and ideas below. 

How to Cook Macaroni & Cheese

Packaging Changes

Be aware of the packaging for the macaroni and cheese. It seems that Costco has gone away from aluminum foil trays and has transitioned to mostly all plastic containers for their prepared meals.

I’m not a fan of the change as foil trays bring more of a feeling of quality while also being more convenient as they can be put directly into the oven.


The new plastic tray can not be used to bake this macaroni and cheese. Costco has even included a large sticker stating so on the package. 

In order to bake the mac and cheese, you would have to transfer it from the packaging into an oven safe dish. This isn’t the end of the world, but you are going to have an appropriately sized dish on hand.


I used a glass pie plate that turned out to be a great size for this mac and cheese from Costco. 

Presentation is sacrificed, and there is also one additional dish that needs to be washed now as well.

How to Cook Costco’s Mac and Cheese

Aside from finding a suitable oven safe dish and transferring the mac and cheese, the dish is rather easy to make. You simply need to pop it into the oven for 40-60 minutes. 

  • Preheat Oven to 400°F. 
  • Remove from the package.
  • Place into an ovenable pan and cover with foil. 
  • Place onto a baking sheet. 
  • Place on the center rack of the oven.
  • Bake for 40-60 minutes or until the internal temperature reaches 165°F.

Macaroni & Cheese Serving Suggestions

The Costco mac and cheese is bland, and definitely needs some help. Luckily, there are a lot of options that will really go well with side dishes to spruce it up.


If you want to keep it basic, the mac and cheese will go well with some common seasonings. Any of these would add another layer of flavor. 

  • Garlic Powder
  • Onion Powder
  • Smoked Paprika
  • Oregano
  • Basil
  • Crushed Red Peppers
  • Chili Powder
  • Cayenne

Macaroni and Cheese Balls

I originally had the intention to use a few of these recipes to spruce up the mac and cheese, but because none of us enjoyed the dish the night before, my wife took the liberty and used all the remaining mac and cheese to make make and cheese balls. 


Spicy Mac and Cheese

Mac and cheese is good, but spicy mac and cheese is great. Crushed red peppers are a great option, but so is hot sauce. Tabasco or buffalo sauce would be great with the mac and cheese.

Bacon Ranch Macaroni and Cheese

A favorite of mine is going to be bacon ranch macaroni and cheese. Fresh bacon is excellent, but bacon bits also work as well. 

Combine the bacon with the macaroni and cheese and mix in some ranch for a delicious entree or side dish.

Homemade Mac and Cheese Balls

Pulled Pork Mac and Cheese

To transform the mac and cheese from a side dish to an entree, you could add some pulled pork. There are many options to make your own pulled pork, or you could even buy some from Costco.

Chicken Sausage Mac and Cheese

The easiest way to turn mac and cheese into an entree is by adding a protein. 

The sweetness of the Aidells’ Chicken Apple Sausage would be a perfect addition to the meal.

Other Options

For simple combine and eat options, mix the macaroni and cheese with some 505 hatch chiles or even some basil pesto. 

Costco Nutritional Information - Macaroni and Cheese

Nutritional information can be hard to find for Costco items that are made in house. This goes for both the bakery items and deli prepared meals. 

Thanks to 
reddit, I have Costco’s macaroni and cheese nutritional information.

How Many Calories in Kirkland Signature Macaroni and Cheese?

One serving of Macaroni and Cheese is going to be 1 Cup or 4.9 ounces. There are approximately 12 servings per container of mac and cheese. 

Each serving contains 270 calories with 14 grams of fat, 22 grams of carbs, and 14 grams of protein.

Nutritional Analysis

This is actually a slightly better nutritional label than I expected for this mac and cheese. I knew the fat was going to be slightly high because of the cheese, but the carbs were a little surprising to me as I thought there would be more carbs per serving. 

22 grams of carbs isn’t great, but also isn’t bad for this macaroni and cheese.

The 14 grams of protein was a nice surprise and really helps make this a more well balance side dish in terms of macro nutrients.


Each serving is also going to contain 420 mg of sodium or 17% of the recommended daily value. 

This isn’t the worst, but given that this is more a side dish, the sodium is going to add up when combined with an entree.

Costco’s mac and cheese is a miss. The price is fair, and the large tray would be great for parties.

Final Thoughts

I didn’t care for the mac and cheese from Costco. The price is ok for the dish, but not stellar. 

The dish is very very light on flavor and needs a lot of help. Thankfully mac and cheese is pretty easy to improve with some seasoning or toppings. 

This is only a buy if you have a specific plan for the mac and cheese.
