Blackstone Roasted Mushrooms and Onions
Prep Time:
10 minutes
Cook Time: 10–15 minutes
️ Serves: 4
Ingredients:
2 tablespoons olive oil (or butter)
1 pound mushrooms (baby bella, white button, or a mix), sliced
1 large yellow onion, thinly sliced
3 cloves garlic, minced
1 tablespoon soy sauce (adds umami and depth)
1 teaspoon Worcestershire sauce (optional)
Salt and freshly ground black pepper, to taste
½ teaspoon dried thyme or Italian seasoning (optional)
Fresh parsley, chopped (for garnish)
Instructions:
Preheat the Griddle:
Set your Blackstone griddle to medium heat.
Add oil or butter and let it melt and coat the surface.
Cook the Onions:
Add sliced onions to one side of the griddle.
Cook for 4–5 minutes, stirring occasionally until they start to soften and caramelize.
Add Mushrooms:
Add mushrooms to the griddle (separately at first for better browning).
Let them sit untouched for a minute or two before stirring—this helps them roast instead of steam.
Combine & Season:
Mix mushrooms and onions together.
Add garlic, soy sauce, Worcestershire (if using), salt, pepper, and thyme.
Stir frequently for another 5–7 minutes until mushrooms are golden brown and onions are tender.
Finish:
Taste and adjust seasoning.
Garnish with fresh parsley if desired.

Add to a burger or sandwich
