Cheese is the lifeblood of fast food. It’s gooey, melty, and the reason we keep going back for that extra slice on our burgers, tacos, or even chili-topped fries. But have you ever stopped to wonder what’s really in the cheese at your favorite fast food spot? Spoiler alert: it’s not always 100% cheese.
Let’s dive into the world of fast food chains that don’t use real cheese (or at least don’t use it in its purest form). You might be surprised to learn how much of that creamy yellow stuff is actually oil, fillers, and additives.
1. IHOP
While IHOP is best known for its pancakes and syrup, its savory dishes—like omelets and breakfast sandwiches—frequently use processed cheese blends.
These blends often include oils and stabilizers to enhance their texture and shelf life. For example, their omelets are packed with shredded cheese that melts perfectly but contains more additives than actual dairy.
The cheese sauce in their lunch menu items, like burgers and loaded fries, follows the same formula. What makes IHOP’s processed cheese so popular is its consistency—it melts smoothly and adds a creamy, rich flavor to their dishes.
However, for cheese purists, it’s far from an authentic experience. It’s a reminder that not all “melty goodness” comes from real cheese.
2. Jack in the Box
When you think of Jack in the Box, you probably imagine their tacos, burgers, and loaded curly fries. However, the cheese they use on almost all of their menu items is heavily processed.
Their classic “American cheese” slices are made with a blend of cheese, milk solids, and oil, which gives them that distinct glossy melt.
But the real star offender is their nacho cheese sauce, which is far from dairy. This sauce is a concoction of emulsifiers, artificial flavors, and stabilizers designed for easy storage and quick preparation.
he tacos, a fan favorite, feature a slice of processed cheese that melts just enough to complement the crunchy shell. While undeniably tasty, the cheese at Jack in the Box is more about engineering than authenticity.
3. Taco Bell
Taco Bell is a go-to spot for cheesy indulgence, but their cheese game leans heavily on processed products. While their shredded cheese—used in tacos and quesadillas—comes closer to real cheese, their beloved nacho cheese sauce is a different story.
This bright orange goo is a mix of oils, artificial flavors, and emulsifiers designed to stay creamy at any temperature. The nacho cheese sauce is often featured in fan-favorites like the Nacho Fries, Doritos Locos Tacos, and the Crunchwrap Supreme.
Despite its artificial origins, it has a loyal following due to its bold, salty flavor and velvety texture. But if you’re looking for authentic queso, Taco Bell’s version is unlikely to satisfy your cravings.
4. Applebee’s
Applebee’s may position itself as a casual dining spot, but its approach to cheese is strikingly similar to fast food.
Many of their dishes—from burgers to their famous spinach and artichoke dip—rely on processed cheese blends. These blends often feature a mix of dairy and non-dairy ingredients to achieve that creamy consistency diners love.
For example, the dip’s “cheese” is bolstered with stabilizers to keep it gooey even after reheating. Their burgers and sandwiches also feature processed cheese slices for a uniform melt.
While the flavors are rich and satisfying, the lack of pure dairy might surprise diners who assume they’re getting the real deal.
5. Sonic Drive-In
Sonic’s menu is all about indulgence, but their cheese is another example of processed perfection. The American cheese slices on their burgers and hot dogs include emulsifiers and stabilizers to create that ideal melt.
This processed approach also extends to their chili cheese fries and tots, which are smothered in a thick, gooey cheese sauce. The sauce is primarily made of oils, flavorings, and thickeners, giving it a velvety texture that’s hard to resist.
Sonic’s use of processed cheese ensures a consistent experience for customers, but it’s far from real, artisanal cheese.
6. Bojangle’s
Bojangle’s might win you over with their buttery biscuits, but the cheese in their breakfast sandwiches and sides is a processed blend that’s heavy on stabilizers and additives. This makes the cheese easy to store and melt, but it’s far from “real” dairy.
Whether it’s a cheddar-like slice in a biscuit sandwich or a bowl of mac and cheese, Bojangle’s relies on blends designed for consistency rather than authenticity.
The processed cheese adds a creamy, slightly salty punch to their menu items, which pairs perfectly with their savory biscuits.
7. McDonald’s
Here comes the king of processed cheese. Their iconic American cheese slices—used on everything from Big Macs to Filet-O-Fish sandwiches—are only about 60% real cheese. The rest is a combination of emulsifiers, preservatives, and oils that give it that trademark creamy melt.
This cheese is designed to hold its texture under heat lamps and to provide that consistent flavor customers have come to expect.
Even the cheese used in McDonald’s breakfast items, like the Egg McMuffin, follows the same processed formula. While it’s engineered to perfection, dairy lovers seeking authenticity won’t find it here.
8. Five Guys
Five Guys is transparent about their use of processed cheese. The American cheese slices on their burgers are a blend of dairy and additives that create that nostalgic diner-style melt. Each slice is carefully selected to achieve that ooey-gooey texture that Five Guys fans love.
The cheese complements their fresh patties and toasted buns perfectly, creating a burger experience that feels indulgent and satisfying.
While it’s a crowd-pleaser, the cheese is designed for texture and flavor over authenticity. That said, Five Guys fans might argue that the rich, gooey melt is worth the trade-off, even if it’s not 100% real cheese.
9. Chili’s
Chili’s is known for its Tex-Mex-inspired dishes, but their cheese offerings often lean on processed products. Their queso dip, a fan favorite, is made with a blend of emulsifiers and oils to maintain its creamy consistency.
Even the shredded cheese on their burgers and nachos is typically a mix of real cheese and stabilizers.
Their fajitas, a staple menu item, are often topped with shredded cheese blends that prioritize meltability over authenticity.
10. Pizza Hut
Pizza Hut’s mozzarella might look like the real thing, but it’s often a blend that includes modified food starch and oils to keep it stretchy and shelf-stable.
Their stuffed crust cheese is a particular offender, with a processed cheese filling that’s engineered for that perfect pull. Even their shredded cheese toppings are often blends that include stabilizers to enhance meltability.
While Pizza Hut’s cheese products deliver on texture and flavor, they’re far from artisanal.
11. Tim Hortons
Tim Hortons’ cheese might not be the main attraction, but their breakfast sandwiches and wraps often feature processed cheese slices.
These slices are designed for their glossy texture and easy melting, thanks to stabilizers and additives. The cheese pairs well with their egg patties and bagels, creating a satisfying breakfast option for on-the-go diners.
However, for those who prefer real dairy, the synthetic quality of Tim Hortons’ cheese might be a letdown.
12. Dairy Queen
DQ is famous for its ice cream, but their savory menu leans heavily on processed cheese. Whether it’s the slices on their burgers or the cheese curds in their sides, the dairy content is often diluted with oils and stabilizers.
The cheese sauce on their chili fries is another example of a product designed more for convenience than authenticity.
While the flavors are rich and creamy, the lack of genuine cheese content underscores Dairy Queen’s focus on fast food efficiency.
13. Arby’s
Arby’s cheddar sauce is a star ingredient in many of their sandwiches, but it’s far from real cheese. The sauce is a processed blend designed for smooth pourability and a bold, salty kick.
Even the sliced cheese used in their sandwiches often includes stabilizers and emulsifiers for that perfect melt. The processed nature of their cheese complements Arby’s bold meat flavors, but it’s not the authentic cheddar many expect.
14. Burger King
Like many fast food chains, Burger King relies on processed cheese for its burgers. Their American cheese slices are a mix of dairy and additives, designed for a consistent melt and long shelf life.
The cheese’s smooth, uniform texture makes it a staple on classics like the Whopper and Cheeseburger. However, this convenience-focused approach sacrifices the authenticity of real cheese.
While it’s engineered for fast food perfection, cheese aficionados might miss the complexity of traditional dairy products.
15. Subway
Subway’s cheese options, from shredded mozzarella to American-style slices, are blends that rely on oils and stabilizers for that perfect sandwich finish. Even their cheese sauces, used in select menu items, are more artificial than dairy-driven.
The emphasis is on creating a consistent texture and flavor that pairs well with their bread and fillings. However, for those seeking genuine cheese, Subway’s processed options might feel like a compromise.
16. Denny’s
Denny’s cheesy menu items often include processed slices and cheese sauces. Whether it’s their omelets, burgers, or loaded fries, the cheese is typically a mix of dairy and non-dairy ingredients.
This gives it that creamy consistency diners love but makes it far from the real thing. The processed nature of their cheese allows it to melt evenly and enhance the flavors of their savory dishes.
However, for those who value traditional cheese, Denny’s processed blends might not hit the mark.
