Okay, so this burger? It’s a total throwback for me. I used to get the Mushroom Swiss Burger from Hardee’s in high school when I wanted something that felt a little extra without being too over-the-top. That rich mushroom sauce, the melty Swiss, and that juicy burger — it was comfort food at its best. So when I had a craving and nowhere nearby to grab one, I figured, why not make it myself?
And y’all, this homemade version delivers. It’s savory, melty, earthy, and way easier than you’d think. The sauce alone is worth the effort — I’ve been drizzling it on steak, chicken, even roasted potatoes. This one’s definitely going into my regular burger night rotation.
Why You’ll Love This Recipe
This Mushroom Swiss Burger is everything a comfort food burger should be — rich, juicy, and loaded with creamy, savory flavor. The mushrooms are cooked down until they’re golden and full of umami, then smothered in a simple, flavorful cream sauce that ties the whole thing together.
It’s fast enough for weeknights and satisfying enough for guests, and the homemade version gives you control over the ingredients, spice level, and how melty you want that cheese. If you love Hardee’s classic burger, this version will blow you away.
What You’ll Need

- 1 tablespoon olive oil
- 8 oz mushrooms (baby bella or white), sliced
- 1 garlic clove, minced

- ½ cup heavy cream
- ½ teaspoon Worcestershire sauce
For the burgers:
- 1 lb ground beef (80/20 for best flavor)

Tools You’ll Need
- Cast iron or nonstick skillet
- Spatula
- Mixing bowl
- Small saucepan
- Knife and cutting board
- Grill or stovetop for burgers
- Spoon or ladle
Substitutions & Variations
- Swap ground beef with turkey, chicken, or plant-based patties.
- Try provolone, Havarti, or mozzarella instead of Swiss.

- Lighten the sauce with Greek yogurt and broth instead of cream.
- Add soy sauce or Parmesan to the mushrooms for more umami.
Make Ahead Tips
The mushroom sauce can be made up to three days ahead and reheated gently. Burger patties can be shaped up to 24 hours in advance and kept chilled until cooking.
Instructions
1. Make the Mushroom Sauce
In a skillet, melt butter with olive oil over medium heat. Add mushrooms and cook for 6–8 minutes until golden. Stir in garlic, salt, and pepper. Add beef broth and Worcestershire, simmer for 2 minutes, then add cream. Cook until thickened, about 3–5 minutes. Keep warm.
2. Form the Patties
Divide beef into 4 portions and shape into patties about ½ inch thick. Press a thumb indent in the center. Season both sides with salt and pepper.
3. Cook the Burgers
Heat a skillet or grill to medium-high. Cook patties for 4–5 minutes per side, or until done to your liking. In the last minute, top each patty with Swiss cheese and cover to melt.
4. Toast the Buns
Melt butter in a skillet or on the grill and toast buns until golden.
5. Assemble
Place patties on buns, spoon mushroom sauce generously over each, add toppings, and serve hot.
Serving Suggestions
- Pair with fries, sweet potato fries, or tater tots
- Add a crisp side salad with vinaigrette
- Serve with garlic green beans or roasted broccoli
- Try onion rings for crunch
- Add dill pickles or pickled onions for tang
Leftovers & Storage
Keep patties and mushroom sauce stored separately in airtight containers in the fridge for up to three days. Reheat patties in a skillet and warm sauce gently on low. Build fresh burgers when ready to serve.
Nutrition & Benefits
This burger is indulgent but balanced. Mushrooms add antioxidants and B vitamins, while beef offers protein and iron. Using fresh ingredients keeps it cleaner than fast food. For lighter options, swap leaner meat and use milk or Greek yogurt in the sauce.
Recipe FAQ
What mushrooms are best? Baby bella or white mushrooms are perfect, but shiitake add extra depth.
Can I grill the burgers? Yes, grilling adds smoky flavor and works great.
How do I melt Swiss cheese well? Cover the pan briefly at the end of cooking to trap steam.
Can I freeze the mushroom sauce? Cream sauces don’t freeze well. Refrigerate and use within a few days.
How do I thicken the sauce? Simmer longer or stir in a little cornstarch slurry.
The Final Bite
This Mushroom Swiss Burger hits that sweet spot of savory, creamy, and satisfying. It’s the kind of recipe that makes a regular weeknight feel special, and if you grew up on Hardee’s like I did, it’ll taste like pure nostalgia — only fresher and even better.
I’ll be making this one again and again, not just for burgers but for that sauce alone. Trust me, it’s worth keeping in the rotation.
