Know About Your Ingredients:  

Red onion: ½ cup red onions, minced. Onions give dishes a rich umami flavour and a subtle sweetness. 

Mushroom: 8 oz. mushrooms of choice (2 packages), sliced, chopped, and divided. Mushrooms are an excellent source of protein, dietary fibre, and antioxidants.

Mushroom cream: 10 oz cream of mushroom(1 can).

Worcestershire sauce: 1 tsp. Worcestershire sauce. It is sour from tamarind and vinegar, sweet from molasses and sugar, and spicy.

Swiss cheese: 1 cup grated Swiss cheese. It is a good source of protein and calcium.

Beef: 1¼ lb ground beef. It has a lot of healthy nutrients, including protein, vitamins, and minerals.

MSG: 1 tbsp MSG, accent or any flavour enhancer.

Garlic salt: 1 tsp. garlic salt. Garlic salt is crushed garlic mixed with salt.

Black pepper: 1 tsp. ground black pepper. Black pepper makes food taste richer and spicier.

Olive oil: 2 tbsp olive oil. Olive oil adds flavour and texture to sauces and marinades without adding calories or saturated fat.

Red wine: ¼ cup red wine. Red wine is made from purple, black, blue, and other dark-skinned grapes.

Salt: ¼ tsp salt. The flavour of salt is neutral, but it also helps to bring out the aroma of other ingredients.

Buns: 5-hamburger-buns.

Potato fries: Potato fries for sides. 

How to Make Mushroom and Swiss Burger Sauce?

Step 1: In heated oil, onions must be sautéed till translucent. Add 1 package, or 8 ounces, of mushrooms and saute briefly.

Step 2: Deglaze with red wine and reduce briefly. Add salt and pepper, then adjust the seasoning. Leave the mushrooms aside until they are improbable.

Step 3: Combine the mushroom soup, the last package of mushrooms, 8 ounces, and the Worcestershire sauce. Put it on a simmer and let it cook for a bit.

Step 4: Preheat your flat griddle and grease it accordingly.

Step 5: Mix the MSG, flavour enhancer, garlic salt, and ground pepper in another bowl. Set aside.

Step 6: Mix the cooled mushrooms with the ground meat until everything is evenly distributed. Try and add 1 tablespoon of your favourite seasoning blend.

Step 7: To make hamburger patties, portion 6 ounces of ground beef into balls and form them into balls. Wrapping the patties in plastic wrap will help them maintain their shape.

Step 8: Grill your patties and season both sides with the seasoning mix. Toast your hamburger buns on the grill.

Step 9: Cover the burger with the top bread and 1 tablespoon of the mushroom mixture. Do the same with the remaining patties.

Step 10: One cup of potato fries should be served beside the burger.

Creamy Mushroom Burger Sauce

This creamy mushroom sauce is excellent for topping pasta, steak, mashed potatoes, omelettes, or as a dipping sauce for a crusty baguette. Sour cream gives the sauce just the right amount of tang and creaminess and makes the sauce thicker.

Know About Your Ingredients:  

  • 1 lb white or brown mushrooms
  • 1/2 cup yellow onion
  • 2-3 cloves of garlic, minced
  • 4 tbsp oil or butter
  • 1/2 cup white wine (or broth if not used)
  • 1 cup heavy cream
  • 1/2 cup sour cream
  • Half a teaspoon of kosher salt (less if using table salt)
  • 2 tbsp. chopped parsley (optional)
  • 2 tbsp. chopped dill (optional)
  • 1/2 tsp coarsely ground black pepper
  • 1/4 cup of Parmesan cheese gratings (optional but recommended)

How to Make Creamy Mushroom Burger Sauce?

Step 1: Wipe 1 lb of mushrooms with a moist paper towel. Make thick slices of them. Peel a half cup of yellow onion and cut it into small pieces.

Step 2:  Chop the 2 tablespoons of parsley and dill if you’re using them.

Step 3: In a huge saucepan, heat 4 tablespoons of oil or butter; add onions and cook on medium heat, constantly turning, until browned and transparent. Spoon the onions into a bowl.

Step 4: Heat the remaining oil or butter until it’s practically smoking in a saucepan. Stir often to brown the mushrooms. Continue cooking until it dries, then fry the mushrooms.

Step 5: Put in a half cup of white wine and sauté the pan by stirring the mushrooms while scraping the bottom. Most of the wine should have drained after 2 minutes.

Step 6: Add the sauteed onion, 1 cup heavy cream, 1/2 cup sour cream, 1 1/2 tsp salt, 1/2 tsp pepper, 2-3 chopped garlic cloves, and 1/4 cup grated cheese to the mushrooms (if using). Cook until the sauce thickens. If the sauce is too thin, add broth or water and mix.
Step 7: If using, finish the sauce by stirring in 2 tbsp of parsley and 2 tbsp of dill.
