Hardee’s has been around for years, serving up burgers that feel like pure comfort food. But one thing that really stands out is their mushroom swiss burger sauce — the same one that made the Mushroom & Swiss Burger a classic and popular among the people.
Hardees Mushroom Sauce Recipe not something magical but they are the best when it’s comes to this mashroom sauce.
Few months back, my cousin Jake stopped by Hardee’s after work. He ordered the Mushroom & Swiss, took one bite, and said, “Man, this sauce tastes is so awesome.” He wasn’t wrong at all.
I also took few bites and loved it. It wasn’t just another fast-food bite — it was warm, creamy comfort that hit the right spot. That rich sauce, loaded with tender mushrooms, buttery flavor, and that touch of beefy depth, made the burger unforgettable.
I wanted that same taste at home — the one that melts into the Swiss cheese and hugs the burger patty just right.
This sauce isn’t only for burgers. It’s amazing with steak, chicken, pasta, or even spooned over mashed potatoes.
If you’ve ever loved that Hardee’s flavor, you’ll want to keep this mushroom burger recipe close.
How Does Hardee’s Mushroom Sauce Taste?
Taste of this swiss burger mushroom sauce is super creamy and packed with flavor. It’s savory with a hint of earthiness.

Hardee’s Mushroom Sauce Ingredients
Cream of Mushroom Soup (Campbell’s, 10.5 oz) – The base that keeps everything creamy and smooth. It brings that familiar diner flavor you get in every Hardee’s bite.
Sliced Mushrooms (4 oz can, drained) – Use regular button mushrooms. Canned works great here — they soak up flavor and keep the sauce chunky in the best way.
Beef Gravy (½ can, about 5 oz) – Any store brand is fine. Adds the rich, beefy layer that gives this sauce its depth.
Unsalted Butter (1 tsp, optional) – Melted in at the end for extra shine and silky texture. Totally worth it.
Salt + Black Pepper (to taste) – Just a pinch of each to wake up the flavors.
How To Make Hardee’s Mushroom Sauce
Step 1: Prepare Your Ingredients
Open the cream of mushroom soup and beef gravy cans. Drain the liquid from the can of sliced mushrooms completely so that only the mushroom pieces remain.
This helps prevent the sauce from becoming too thin. Have all your ingredients ready near the stove.
Step 2: Combine Soup and Mushrooms
Place a small saucepan on the stove over medium heat. Add the entire can of cream of mushroom soup into the pan. Then add the drained sliced mushrooms.
Stir gently using a spatula or spoon until the mushrooms are evenly distributed throughout the soup.
Step 3: Add the Beef Gravy
Open the beef gravy can and pour in about half of it (approximately ½ cup or 5 ounces). Stir the mixture until everything is well blended.
Tip: You can adjust the amount of beef gravy to your liking. Adding more gravy makes the sauce thinner and gives it a deeper beef flavor; adding less keeps it creamier and more mushroom-forward.
Step 4: Simmer the Sauce
Turn the heat up slightly until the sauce starts to lightly bubble (a gentle boil). Once bubbles appear, immediately lower the heat to low and let it simmer for 5–7 minutes, stirring occasionally.
This simmering step allows the mushroom, beef, and cream flavors to meld into a smooth, rich sauce.
Step 5: Finish and Adjust
After simmering, taste the sauce. If desired, add a small pinch of salt and black pepper to enhance the flavor. For extra depth, stir in 1 teaspoon of butter right before serving — it gives the sauce a silky texture similar to the one used in Hardee’s kitchen.
Step 6: Serve
Your Hardee’s-style Mushroom Sauce is now ready. Spoon it generously over a freshly cooked beef patty topped with Swiss cheese to recreate the classic Hardee’s Mushroom & Swiss Burger.
Helpful Tips
- Drain and prep right. Make sure your mushrooms are drained so the sauce stays thick and rich.
- Simmer gently. Keep the heat low and stir occasionally for a smooth, velvety texture.
- Boost flavor smartly. A splash of Worcestershire or soy sauce adds depth, and a teaspoon of butter at the end gives that glossy, restaurant-style finish.
- Customize easily. Add extra mushrooms or a little cream if you like it richer — it’s your sauce, make it your way.
Variations and Substitutions
- Lighter version: Use low-fat cream of mushroom soup or mix in a splash of milk instead of butter.
- Extra creamy: Add a spoon of sour cream or heavy cream at the end.
- Garlic lover: Sauté a small clove of minced garlic before adding the soup.
- Vegetarian: Skip the beef gravy and use vegetable broth or mushroom broth instead.
- Bold flavor: Add a few drops of soy sauce for a deeper color and umami punch.
- Cheesy twist: Stir in some shredded Swiss or mozzarella at the end for a cheesy mushroom sauce.
What to Enjoy with Hardee’s Mushroom Sauce
This sauce isn’t just for burgers. I love pouring it over grilled chicken, pork chops, or even a baked potato.
It goes great with mashed potatoes, noodles, or steamed rice too. Sometimes I just use it as a dip for bread or fries when I want something rich and warm.
If you’ve got leftovers, drizzle it over breakfast eggs or serve it with meatloaf. It’s one of those sauces that makes any simple meal taste special.
Store Leftover & Reheat
Let the sauce cool to room temperature before storing it in an airtight container. Keep it in the fridge for up to four days, or freeze for up to two months.
To reheat, warm gently on the stove, stirring occasionally, or microwave in short bursts, adding a splash of water or milk if it thickens too much.
Hardee’s Mushroom Sauce Recipe FAQs
Can I use fresh mushrooms instead of canned?
Fresh mushrooms work well. Slice thin and sauté in butter before adding the soup. This boosts flavor and texture, giving the sauce a fresher, earthier mushroom taste compared to canned mushrooms.
What type of beef gravy works best?
Choose a rich, flavorful canned or jarred beef gravy. Darker, thicker gravies add more depth, while lighter ones still work but may produce a milder sauce.
Can I make it without beef gravy?
Yes, substitute with mushroom or vegetable broth. The sauce remains tasty and creamy, though it won’t have the same rich, savory depth as the original version.
Is this sauce gluten-free?
It depends on your soup and gravy. Some canned versions contain gluten, so check labels carefully if gluten-free is important.
Can I store this sauce overnight?
Store in an airtight container in the fridge for up to four days. Reheat gently on the stove or microwave, stirring occasionally to restore smoothness.
How can I make it thicker?
Simmer uncovered a few extra minutes to reduce liquid, or whisk in a small cornstarch-water mixture. Both methods give a richer, thicker sauce without changing flavor.
Can I add onions or garlic?
Yes, lightly sauté chopped onions or minced garlic at the start. It enhances flavor without overpowering the mushrooms, keeping the sauce balanced.
What can I use instead of cream of mushroom soup?
Make a quick homemade base: cook chopped mushrooms in butter, add a little milk, and whisk in flour. It produces a creamy texture similar to the canned version.
