In a bowl mix together balsamic vinegar, soy sauce, sriracha and brown sugar. Mix well and set aside.
Heat olive oil in a cast iron skillet (or any other pan) on medium heat. Once the oil is hot, add the sliced garlic and let them cook until they start changing color, around 2 minutes.
Then add the sliced mushrooms and stir. Cook the mushrooms on medium heat for 6 to 7 minutes until they release all the moisture and start turning golden-ish in color.
Add in the prepared sauce to the pan. Mix well until sauce is well combined with the mushrooms.
Add the black pepper and stir well.
Cook for a minute and then turn off the heat. Stir in the basil.
Serve these balsamic mushrooms with more basil. These can be enjoyed with rice, noodles or even on a toast!
Notes
I have not added any salt here since the soy sauce and vinegar already have salt in them and that was good enough for me. You can always add salt as per your preference.
To make this a little spicy, you can add some crushed red chili flakes.
This recipe makes a small serving and you can easily double it.
