Hardee’s Mushroom & Swiss Burger Price Calories Review

Most Hardee’s burgers lead with beef and sauce. The Mushroom & Swiss takes a different route entirely — it leads with umami. A Quarter Pound 100% Angus beef patty, melted Swiss cheese, and a creamy mushroom sauce on a toasted brioche-style bun. No Special Sauce, no bacon, no layered toppings. Three components, one clear flavor direction.

Customers order the Hardee’s Mushroom & Swiss when they want something more interesting than a standard cheeseburger but do not want the calorie load that comes with a double-patty build. The mushroom sauce is the defining element — a creamy, earthy topping that completely changes the flavor identity of what would otherwise be a straightforward beef-and-Swiss sandwich. On the Hardee’s burger menu, it sits comfortably as the most flavor-forward single-patty option outside of the Frisco Burger.

This burger is best suited for customers who appreciate umami-forward flavors, anyone who prefers Swiss cheese over American, and people looking for a satisfying burger at a lower calorie count than most other Hardee’s options.

What’s on the Hardee’s Mushroom & Swiss Burger?

The simplicity of this build is deliberate, and it works because the mushroom sauce carries enough weight to anchor the whole burger. It is a creamy, earthy sauce with a savory depth that settles into every bite — the kind of topping that makes you understand why mushroom-and-Swiss has been a classic pairing in steakhouse cooking for decades.

Swiss cheese plays a supporting role here that American cheese cannot match. Its nuttier, more complex flavor profile complements the earthiness of the mushroom sauce rather than competing with it. American cheese would overwhelm the sauce with salt and processed sharpness — Swiss lets the sauce lead while adding its own subtle layer.

The charbroiled Angus beef patty underneath brings the same open-flame character as every other Hardee’s burger, and the brioche bun keeps the build soft and neutral enough to let the mushroom sauce and Swiss define the flavor experience rather than getting in the way.

Compared to the Famous Star®, which builds flavor through sauce complexity and fresh vegetable contrast, the Mushroom & Swiss builds flavor through depth and richness with no acidic element to cut through it. That is a meaningful distinction — this is a more indulgent, less “fresh” eating experience, despite its relatively modest calorie count.

Hardee’s Mushroom & Swiss Burger Price

Prices vary by location, state, and franchise owner. Hardee’s franchise-operated structure means pricing can shift depending on local operating costs, regional market conditions, and individual franchise decisions. A Mushroom & Swiss that costs $6.49 in one state may run $7.49 at a location in a higher-cost area, and highway or airport locations typically run higher than standalone restaurants.

For the price, this burger delivers genuine value — particularly for calorie-conscious customers. Roughly $6.50–$7.50 for a Quarter Pound Angus patty, Swiss cheese, and a distinctive mushroom sauce is competitive with similar-positioned items at other chains, and the Mushroom & Swiss sits at a lower price point than the Frisco Burger while offering a similarly distinctive flavor identity.

Calories & Nutrition Facts

Source: FatSecret (560 cal / 224g serving), verified against CalorieKing and FastFoodNutrition.org. Minor variation exists across trackers due to different serving size records. Sodium estimate derived from available composite data.

The calorie range reflects a minor discrepancy between tracker databases — FatSecret records 560 calories for a 224g serving of the single-patty version, while CalorieKing and FastFoodNutrition.org record 620 calories for a 221g serving. Both track the same Quarter Pound single-patty build; the difference likely reflects a recipe variation or measurement difference between data entry points. Either way, this is one of the lowest-calorie options among Hardee’s charbroiled burgers.

At 560–620 calories, the Mushroom & Swiss Single is the lightest full charbroiled burger on the Hardee’s menu — lower than the Famous Star® (660 cal), Frisco Burger (860 cal), Super Star® (950 cal), and Monster Burger® (1,140 cal). For anyone managing calorie intake at a fast-food stop, this is the strongest option among full-size Hardee’s burgers.

Protein at 30–33 grams is reasonable for a single-patty burger, though not exceptional. The sodium content (~1,280mg) is moderate by Hardee’s standards — notably lower than most other burgers on the menu. Anyone managing blood pressure or sodium intake will find it the most approachable full-size option in the lineup. The saturated fat (~13g) is still worth noting for anyone monitoring cardiac health, though it falls below the limits of the other Hardee’s burger options.

Is the Mushroom & Swiss Burger Healthy?

Relative to the rest of the Hardee’s burger menu, yes — it is the most nutritionally moderate full charbroiled burger available. The calorie count is the lowest among full-size options, sodium comes in well below most competitors on the menu, and the cholesterol figure is among the lower readings for a beef burger of this size.

In absolute terms, 560–620 calories with ~1,280mg of sodium is still a substantial meal, and the saturated fat content means it is not something to eat daily without consideration. For weight management goals, it fits into most calorie budgets as an occasional meal without requiring much planning. Keto dieters can order it without the bun to cut carbohydrates significantly, leaving a high-fat, moderate-protein meal. For general health-conscious fast-food eating, this is the most defensible full-burger option at Hardee’s.

How Does the Hardee’s Mushroom & Swiss Burger Taste?

The brioche bun is soft and lightly toasted on the inside surfaces — it does exactly what a neutral bun should do, which is let everything sitting on top of the beef patty drive the experience. There is nothing distinctive about the bun itself, and that is fine; the mushroom sauce has more than enough flavor to carry the burger without any help from the bread.

The Angus beef patty brings the same charbroiled depth that defines Hardee’s burgers — a light smoky char on the exterior, juicy inside, with a clean beef flavor that reads distinctly more “grilled” than flat-top competitors. One Quarter Pound delivers enough presence to hold its own under the sauce, though the mushroom sauce is assertive enough that the beef becomes a supporting player more than the lead.

Swiss cheese melts evenly across the patty and adds a subtle nuttiness that sits well beside the earthier notes of the sauce. This is one of the few fast-food burgers where the cheese choice actually matters to the final flavor — American cheese here would flatten the umami experience that makes this burger interesting.

The mushroom sauce is the whole show. Creamy, earthy, savory, with a richness that coats each bite and lingers. It reads somewhere between a classic French mushroom cream sauce and a fast-food gravy — not as refined as the former, but significantly more complex than anything you would find on a standard fast-food burger. The earthiness pairs naturally with the charbroiled beef, and together they create a flavor profile that is genuinely hard to find at this price point in a fast-food setting.

There is no acidity here — no pickles, no tomato, no Special Sauce tang to cut through the richness. Each bite is rich, savory, and consistent. Whether that is satisfying or monotonous depends entirely on what you want from a burger. Customers who love earthy, umami-driven food will find this deeply satisfying. Anyone who prefers a more balanced, fresh-and-savory contrast will find the Famous Star® more comfortable.

Hardee’s Mushroom & Swiss Burger vs Famous Star®

The Famous Star® is the most logical comparison — same Quarter Pound Angus patty, similar price range, but fundamentally different flavor directions.

Most customers making this choice will land on the Famous Star for an everyday order — it is more versatile, slightly cheaper, and offers a broader topping profile that satisfies a wider range of preferences. The Famous Star’s Special Sauce and fresh vegetables give it a livelier, more balanced eating experience.

The Mushroom & Swiss wins on calorie count (40–100 calories fewer depending on the database) and delivers a more distinctive, umami-forward flavor profile that the Famous Star cannot replicate. Protein is comparable between the two. On value, the Famous Star comes in slightly cheaper while still delivering a well-composed burger — the Mushroom & Swiss asks for a dollar or two more for a more focused, less versatile eating experience.

Flavor-wise, neither is objectively superior — they satisfy entirely different cravings. The Famous Star is the burger for variety and freshness. The Mushroom & Swiss is the burger for depth and richness.

Is the Hardee’s Mushroom & Swiss Burger Worth Ordering?

For the right customer, yes — and it stands out as one of the most genuinely distinctive single-patty options at any fast-food chain. The mushroom sauce elevates what would otherwise be a simple Swiss cheeseburger into something with real flavor identity, and the calorie count being the lowest among full charbroiled Hardee’s burgers makes it an attractive option for customers who want a satisfying meal without the heaviness of the Super Star® or Monster Burger®.

Portion size is honest for a single-patty quarter-pound burger. The mushroom sauce adds satiety through richness rather than volume, so most customers find it filling without needing a side. Quality holds up — the charbroiled beef is consistent across visits, and the mushroom sauce has a reliable flavor that does not vary the way more complex sauce builds can.

Pros:

• ✅ Lowest calorie full charbroiled burger at Hardee’s
• ✅ Most distinctive, umami-driven flavor on the menu
• ✅ Lower sodium than most other Hardee’s burgers
• ✅ Swiss cheese is a genuine flavor upgrade over American

Cons:

• ❌ No fresh toppings — nothing to cut through the richness
• ❌ Monotonous flavor profile if umami is not your preference
• ❌ Minor price premium over the Famous Star for a less versatile build

The honest drawback is the lack of any fresh element to balance the richness. Without lettuce, tomato, or pickles, the burger eats as a continuous wall of savory — satisfying if that is what you want, potentially heavy if you prefer contrast. Customers who find rich, creamy sauces fatiguing halfway through a burger may wish there were a pickle or two to reset the palate.

Who Should Order This Burger?

The Mushroom & Swiss is best suited for customers who specifically want an umami-driven burger, anyone who prefers Swiss cheese to American, and people watching their calorie intake who still want a full-size charbroiled burger without compromising on flavor. It is also the strongest option for anyone who finds the Famous Star’s topping complexity unnecessary and prefers a simpler, richer eating experience.

Final Verdict

The Hardee’s Mushroom & Swiss Burger earns its place on the menu by offering something the rest of the Hardee’s lineup does not: a deeply savory, umami-driven burger that prioritizes flavor depth over topping variety. The mushroom sauce is the reason to order it — earthy, creamy, and complex enough to define the entire eating experience. Swiss cheese supports it well, and the charbroiled Angus beef delivers the same quality foundation as every other Hardee’s burger. Being the lowest-calorie full charbroiled option on the menu is a meaningful bonus that makes it genuinely versatile across different dietary approaches.

Its weakness is the same as its strength: the burger is entirely committed to one flavor direction. No acidity, no freshness, no contrast. Customers who want variety in every bite will be better served by the Famous Star®. Those who want depth, richness, and a flavor profile that holds up as the most distinctive on the Hardee’s menu should order this one without hesitation.

The most nutritionally balanced burger on the Hardee’s menu — held back only by its one-dimensional flavor direction.
