LAKE FOREST, CA – Del Taco, the nation’s second-largest Mexican quick-service restaurant (QSR) chain by unit count, has officially announced a high-profile culinary partnership with PepsiCo to introduce a bold new menu category: the Flamin’ Hot® flavored Queso lineup. This limited-time offer (LTO), which integrates the iconic, high-intensity heat of Cheetos® Flamin’ Hot® seasoning with Del Taco’s signature Queso Blanco, represents a strategic move to capture the attention of flavor-seeking consumers and bolster the brand’s position in an increasingly competitive fast-food landscape.

The collaboration, which is scheduled to run through November 18, 2026, sees the fusion of two powerhouse brands. By marrying the creamy, premium profile of Del Taco’s house-made queso with the cult-favorite "Flamin’ Hot" flavor profile, the company aims to leverage the "spicy" trend that continues to dominate the millennial and Gen Z demographic.

Main Facts: A Fusion of Creamy and Fiery

The centerpiece of this launch is the Flamin’ Hot® flavored Queso, a product of extensive research and development aimed at balancing heat with texture. Unlike traditional spicy sauces that rely solely on liquid heat, this new offering utilizes a base of Del Taco’s premium Queso Blanco—a creamy, white cheddar-based cheese sauce—infused with the specific spice blend that has made Flamin’ Hot® a global phenomenon.

The lineup is not restricted to a single item but is instead integrated across several of Del Taco’s most popular platforms, including:

• Handhelds: The Flamin’ Hot® flavored Queso Burrito and the Flamin’ Hot® flavored Queso Beef Roller.
• Sides and Snacks: Flamin’ Hot® flavored Queso Crinkle Cut Fries and the classic Flamin’ Hot® flavored Queso & Chips.
• Shareables: Loaded Nachos featuring the new spicy queso as a primary topping.

By embedding the new flavor into existing fan favorites, Del Taco is employing a "menu architecture" strategy that minimizes operational complexity while maximizing consumer interest. The rollout is currently active across more than 550 locations in 17 states, marking one of the brand’s most significant LTOs in recent years.

Chronology: The Road to "Project Del Sunrise"

To understand the significance of this launch, one must look at the recent trajectory of the Del Taco brand. Founded in 1964, Del Taco has long positioned itself as a "fresh-flex" provider—a hybrid between traditional fast food and fast-casual dining, emphasizing scratch-made beans, freshly grilled meats, and hand-grated cheese.

In 2025 and 2026, the brand achieved significant critical acclaim, being voted the "Best Fast Food Restaurant" in USA Today’s 10Best Readers’ Choice Awards. Building on this momentum, the company initiated "Project Del Sunrise," a comprehensive business transformation strategy.

Timeline of the Innovation Pipeline:

1. Early 2025: Del Taco concludes a fiscal year focused on operational efficiency and "back-to-basics" quality, resulting in the USA Today top ranking.
2. Mid-2025: The "Project Del Sunrise" initiative is launched. The goal of this project is to modernize the brand’s relevance, upgrade digital footprints, and, most importantly, accelerate the "innovation pipeline" to compete with larger rivals like Taco Bell and Chipotle.
3. Late 2025/Early 2026: PepsiCo and Del Taco begin collaborative testing on flavor profiles. The "Flamin’ Hot" brand, owned by PepsiCo’s Frito-Lay division, is identified as the ideal catalyst for a high-impact LTO.
4. September 2026: The official nationwide launch of the Flamin’ Hot® flavored Queso lineup, intended to carry the brand through the fall season until mid-November.

Supporting Data: The Economics of Heat and Brand Synergy

The partnership between Del Taco and PepsiCo is rooted in strong financial and demographic data. PepsiCo, a global leader in beverages and convenient foods, reported nearly $94 billion in net revenue in 2025. A significant portion of this growth was driven by its "convenient foods" portfolio, which includes iconic billion-dollar brands like Cheetos.

The Power of "Flamin’ Hot"

Market research indicates that the "Flamin’ Hot" flavor profile is more than just a seasoning; it is a lifestyle brand. According to industry analysts, "hot and spicy" flavor profiles have seen a 15% year-over-year increase in mentions on QSR menus. Furthermore, "branded" ingredients (using a known snack brand inside a fast-food item) typically result in a 20-30% higher trial rate among younger consumers compared to generic spicy offerings.

Del Taco’s Market Position

With over 550 units, Del Taco holds the position of the second-largest Mexican QSR in the United States by unit count. While it trails the market leader in sheer volume, Del Taco has consistently outperformed in "per-unit" quality perception. The introduction of the Flamin’ Hot® lineup is designed to close the "cultural relevance gap" by adopting the bold, viral-ready marketing tactics that have historically been the stronghold of its larger competitors.

Sustainability and Growth

The launch also aligns with PepsiCo’s "pep+" (PepsiCo Positive) initiative. As part of this strategic end-to-end transformation, PepsiCo focuses on sustainable growth and community resilience. For Del Taco, partnering with a company that emphasizes a "stronger, more resilient future" provides a layer of corporate social responsibility (CSR) alignment that appeals to modern, ethically-conscious diners.

Official Responses: Leadership Perspectives

The executive leadership at Del Taco has been vocal about the strategic importance of this collaboration. According to Noah Chillingworth, Chief Marketing Officer at Del Taco, the goal was to create a "signature combination" that felt authentic to both brands.

"New FLAMIN’ HOT® flavored Queso adds an unmistakable flavor and signature heat to many popular Del Taco menu items," Chillingworth stated. "The best collaborations create something new while staying true to what guests already love, and the intense heat of FLAMIN’ HOT® flavored Queso does just that."

Chillingworth’s comments highlight the brand’s focus on "incremental innovation"—taking a proven winner (Queso Blanco) and enhancing it with a high-demand flavor (Flamin’ Hot) to drive repeat traffic.

Ulyses Camacho, Chief Transformation Officer at Del Taco, linked the launch directly to the company’s broader evolution. "Bringing together two iconic brands produces new, innovative menu items that are impossible to ignore," Camacho noted. "The FLAMIN’ HOT® flavored Queso LTO represents a major step forward in the expansion of the innovation pipeline at Del Taco, and we’re focused on improving our brand relevance as part of Project Del Sunrise."

Camacho’s mention of "Project Del Sunrise" suggests that this is only the beginning of a series of high-profile collaborations and menu overhauls intended to pivot Del Taco into a more aggressive market position through 2027.

Implications: Reshaping the Mexican QSR Landscape

The introduction of the Flamin’ Hot® flavored Queso lineup has several long-term implications for Del Taco and the wider fast-food industry.

1. The "Branded Ingredient" Arms Race

This move signals that Del Taco is ready to compete in the "branded ingredient" space. For years, other chains have dominated headlines with Doritos-flavored shells or Mac-and-Cheese-filled sandwiches. By securing a partnership with PepsiCo for the Flamin’ Hot® intellectual property, Del Taco is asserting its ability to secure top-tier corporate partnerships, moving away from its traditional "underdog" status.

2. Enhancing the "Value-Quality" Proposition

Del Taco’s brand identity is built on "real food at a real value." The challenge of adding a highly processed, "fun" flavor like Flamin’ Hot® is maintaining that quality image. By using Queso Blanco as the base—rather than a standard processed yellow cheese—Del Taco is attempting to maintain its "fresh-flex" reputation while still offering the "junk food" indulgence that drives LTO sales.

3. Impact on Consumer Loyalty

Limited-time offers are designed to create a "Fear Of Missing Out" (FOMO). By setting a hard end date of November 18, 2026, Del Taco is encouraging a surge in foot traffic during the autumn months. If successful, this could lead to a permanent increase in the brand’s digital app adoption, as many of these specialized offers are promoted heavily through Del Taco’s rewards program.

4. Future of Project Del Sunrise

The success of this rollout will likely dictate the "Phase 2" of Project Del Sunrise. If the Flamin’ Hot® lineup meets its internal sales targets, consumers can expect more cross-brand collaborations. This could include further integration with PepsiCo’s beverage portfolio (such as exclusive Mountain Dew flavors) or additional snack-brand integrations with Frito-Lay.

Conclusion

Del Taco’s launch of the Flamin’ Hot® flavored Queso lineup is more than just a seasonal menu update; it is a calculated strike at the heart of the "flavor-first" QSR market. By combining its award-winning commitment to fresh ingredients with the massive cultural capital of the Flamin’ Hot® brand, Del Taco is successfully navigating the transition from a regional favorite to a national innovator.

As the company moves forward with Project Del Sunrise, the industry will be watching closely to see if this "fiery" strategy can translate into sustained market share growth. For now, fans of the brand have until November 18 to experience the heat of this unique collaboration—a window of time that Del Taco hopes will ignite a new era for the "Best Fast Food Restaurant" in America.
