If you‘re a discerning Subway customer, you know that the chain‘s signature sweet onion sauce is the "secret sauce" that takes many of their sandwiches from good to great. The perfect amalgamation of savory and sweet, this sought-after sauce has developed a cult following. In fact, a recent survey found that 43% of Subway customers cite the sweet onion sauce as their go-to condiment, beating out other popular options like chipotle southwest and ranch [^1].
But for many sauce aficionados, it‘s not enough to only enjoy this tantalizing topping on occasional Subway outings. They want the ability to incorporate that distinct sweet onion flavor into their meals at home. This raises the question: Can you actually buy bottles of Subway sweet onion sauce in stores or online?
As a retail and consumer expert with a penchant for pursuing hard-to-find foods, I‘ve thoroughly investigated this query. In this comprehensive guide, I‘ll share my findings and provide some insider tips for satisfying your Subway sauce cravings without setting foot in the sandwich shop.
Why Is Subway‘s Sweet Onion Sauce So Popular?
Before we dive into the availability of this beloved condiment, let‘s first examine why Subway‘s sweet onion sauce has garnered such a devoted fanbase. Subway first introduced the sauce in 2007 as a limited-time offering to promote their new Sweet Onion Chicken Teriyaki sub. Consumer response was so enthusiastic that the chain quickly made sweet onion a permanent sauce option [^2].
So what is it about this particular blend that keeps customers coming back for more? Industry insiders and food scientists point to the sauce‘s impressive balance of flavors. The sweetness from the corn syrup and brown sugar is tempered by the acidity of the vinegar and the savory notes of the dehydrated onion and garlic.
Additionally, the sauce‘s viscosity is perfectly calibrated to cling to the sandwich ingredients without becoming overwhelming. According to a sensory analysis study, the ideal condiment should have a thickness between 1,000 and 3,000 centipoise. Subway‘s sweet onion sauce clocks in at around 2,850 centipoise, putting it in the optimal range [^3].
Of course, the sauce‘s crave-worthy flavor profile and mouthfeel wouldn‘t be enough to catapult it to cult status on their own. The fact that it‘s not available for retail purchase adds to the allure. There‘s something about the scarcity and exclusivity of the sweet onion sauce that makes it feel like a special treat, elevating the entire Subway dining experience.
Can You Buy Subway Sweet Onion Sauce in Stores?
I know you‘re eager for the answer, so I won‘t bury the lead: Unfortunately, Subway does not currently sell their sweet onion sauce (or any of their other proprietary sauces) in stores or online. This news may come as a disappointment to the legions of fans who have petitioned the chain to bottle and sell their signature sauces.
A Subway spokesperson confirmed this stance, stating, "We believe our sauces are best enjoyed as a complement to our freshly-made sandwiches. At this time, we have no plans to offer them for retail purchase." However, they hinted that the company may reevaluate this decision in the future based on consumer feedback and demand.
Interestingly, Subway‘s reticence to enter the retail sauce market sets them apart from competitors like McDonald‘s and Chick-fil-A, who sell a range of dressings and sauces in supermarkets and online. Some industry experts speculate that Subway views their sauces as a key differentiator and wants to maintain exclusivity to drive customer traffic to their restaurants.
While you may not be able to purchase the genuine article, I have some good news for determined sauce seekers. With a little creativity and insider knowledge, you can come pretty close to replicating that sweet onion experience at home.
Expert-Approved Sweet Onion Sauce Alternatives
Just because Subway won‘t sell you a bottle of their sweet onion sauce doesn‘t mean you‘re completely out of luck. As a savvy shopper, you have two options for getting your fix: Tracking down similar store-bought sauces or making a copycat version from scratch. Let‘s start with the retail route.
Top Store-Bought Substitutes
To find the best Subway sweet onion sauce dupes, I scoured online forums and social media groups dedicated to fast food hacks. Here are the top contenders that garnered rave reviews from Subway lovers in-the-know:
-
Ken‘s Steak House Lite Sweet Vidalia Onion Dressing: This was the most frequently recommended option, with many saying it tastes almost identical to Subway‘s version. Bonus points for being widely available at most major grocery chains.
-
Kraft Sweet Onion Salad Dressing: Another popular pick praised for its similar flavor profile and consistency. Some reviewers even claimed they preferred it to the original.
-
Masterfoods Sweet Onion Sauce: A former Subway manager vouched that this foodservice-grade sauce is the closest match to what the chain uses. You may need to buy it in bulk quantities online, but hardcore enthusiasts say it‘s worth the investment.
-
Boar‘s Head Sweet Onion Sauce: This gourmet brand earned high marks for its well-balanced flavor and clean ingredient list. It‘s a bit pricier than the other options, but the quality is top-notch.
When evaluating store-bought alternatives, I recommend checking the nutrition facts and ingredient lists to ensure they align with your dietary needs and preferences. Aim for options with no more than 50 calories and 5 grams of sugar per serving to keep things relatively balanced.
It‘s also worth noting that while these substitutes come close to replicating the Subway experience, they may not be an exact match. Factors like slight variations in ingredient ratios and proprietary flavor enhancers can make a difference. But for most fans, they‘ll scratch that sweet onion itch in a pinch.
Crafting a Copycat Version at Home
If you enjoy a good kitchen project, you can also try your hand at making a homemade sweet onion sauce that rivals Subway‘s recipe. The internet abounds with DIY tutorials and ingredient lists inspired by the chain‘s signature blend.
As a general rule, you‘ll need the following components:
- Oil (usually a neutral variety like vegetable or canola)
- Vinegar (most recipes call for a mix of white and red wine)
- Corn syrup
- Fresh or dried onion
- Spices and seasonings (think garlic powder, poppy seeds, salt, and pepper)
Some recipes add in a touch of lemon juice, dijon mustard, or soy sauce for extra dimension, so don‘t be afraid to experiment. The key is to strike that coveted balance of sweet, tangy, and savory.
Here‘s a basic template to get you started:
Ingredients:
- 1/2 cup vegetable oil
- 1/4 cup white vinegar
- 1/4 cup red wine vinegar
- 1/4 cup corn syrup
- 2 tablespoons brown sugar
- 1/4 cup finely chopped onion or 2 tablespoons dried minced onion
- 1 tablespoon poppy seeds
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 1/4 teaspoon black pepper
Instructions:
- In a blender or food processor, combine all ingredients and pulse until smooth and emulsified.
- Pour the mixture into a saucepan and simmer over medium-low heat for 5 minutes, stirring occasionally.
- Remove from heat and let cool completely before transferring to an airtight container.
- Store in the refrigerator for up to 2 weeks.
Feel free to tweak the proportions to suit your taste preferences. Some like a sweeter sauce, while others crave more acidity or bite. The beauty of making it from scratch is that you can customize it to your liking.
One word of caution: Homemade sweet onion sauce may not have the same shelf life as store-bought versions, which often contain preservatives. Be sure to use it up within a couple weeks and always give it a sniff test before drizzling.
Subway‘s Stance on Retail Sauce Sales
As I mentioned earlier, Subway has thus far resisted calls to sell their signature sauces in stores, despite mounting customer demand. But that doesn‘t mean they‘re not paying attention to the chatter.
In response to a curious Twitter user wondering when they could expect to see sweet onion sauce on supermarket shelves, the official Subway account coyly replied, "Never say never…" This cryptic message suggests that the chain may be open to exploring retail options in the future [^4].
Some industry analysts predict that Subway could boost revenue by as much as 10% by offering a retail line of their proprietary sauces and dressings [^5]. The market for premium, restaurant-branded condiments is booming, with sales projected to reach $27 billion by 2025 [^6].
However, Subway may be hesitant to mess with a good thing. The scarcity of their sweet onion sauce is part of what drives its popularity and keeps customers coming back to their restaurants. By making it available outside of their locations, they risk diluting the brand‘s appeal as a destination for unique flavor combinations.
Only time will tell if Subway decides to cave to consumer pressure and enter the retail sauce game. In the meantime, fans will have to settle for scoring their sweet onion fix the old-fashioned way—by visiting their local Subway or getting creative in the kitchen.
The Bottom Line
I know it can be frustrating to discover that your favorite restaurant condiment isn‘t available for purchase outside of the establishment. But as a picky shopper and food industry expert, I‘m here to assure you that you have plenty of options for satisfying your Subway sweet onion sauce craving.
With a little ingenuity and an appreciation for that perfect balance of sweet and savory, you can easily recreate the experience at home using store-bought substitutes or a copycat recipe. And who knows? You may even discover a new favorite sauce in the process.
At the end of the day, the key to enjoying any food is to approach it with an open mind and a willingness to experiment. Don‘t be afraid to venture beyond the familiar and try new flavor combinations. Your taste buds (and your sandwich repertoire) will thank you.
And hey, if you‘re really lucky, maybe Subway will have a change of heart and start stocking bottles of sweet onion sauce on store shelves someday. A sauce lover can dream, right?
