Heat the olive oil in a large pan over medium heat.
Once hot, add the diced onion and sauté until translucent, about 5 minutes.
Add the minced garlic to the pan.
Cook for another 2 minutes, ensuring it doesn’t burn.
Stir in the chopped mushrooms.
Season with salt and black pepper.
Sauté until the mushrooms are browned and tender, about 10 minutes.
Pour in the golden mushroom soup.
Stir everything to ensure the sauce coats the mushrooms well.
Let it simmer for about 5 minutes, stirring occasionally.
Serve warm!
