Our Take
Best for
Fans of savory, saucy burgers, and people avoiding egg (there's no mayo).
Skip it if
You like crisp lettuce and tomato on your burger.
The Build
The Mushroom & Swiss uses a quarter-pound Angus patty topped with melted Swiss cheese and a savory mushroom sauce.
It skips the lettuce, tomato and pickles found on other burgers. The flavor comes from the earthy sauce and the mild, nutty Swiss.
It comes on a toasted brioche-style bun.
Single or Double?
The single costs $5.99. The double costs $7.49, so the second patty adds $1.50.
The single Mushroom & Swiss Combo is $8.49, and the double combo is $9.99. Both combos add $2.50 for fries and a drink.
The single is a good mid-priced choice. It costs $0.50 more than the Famous Star with the same 580 calories.
Nutrition
Per Hardee's nutrition guide, the single has 580 calories, 38g of fat, 31g of protein and 1,280mg of sodium.
The double has 860 calories, 60g of fat, 52g of protein and 1,770mg of sodium.
Listed allergens are milk, soy, sesame and wheat. Unlike most other burgers, egg is not listed, because there's no mayo.
Who It's For
Pick it if you like a saucy, savory burger and don't need fresh toppings.
It's also a good option for people avoiding egg, since there's no mayo on it.
The mushroom sauce can soak the bun. Eat it soon after you get it.
