1 lb (450 g) whole mushrooms (button or cremini), cleaned
½ cup (1 stick / 115 g) unsalted butter
4–5 cloves garlic, minced
Instructions
1. Prep the mushrooms
Rinse mushrooms quickly and pat dry.
Trim the stems if needed.

Cut butter into pieces and scatter over everything.
3. Cook
Cover and cook:
LOW for 3–4 hours
HIGH for 1.5–2 hours
Stir once or twice if possible (not required).

Once tender and glossy, give a final stir.
Taste and add a pinch of salt if needed.
Serve warm with the buttery garlic sauce.
Optional (but highly recommended)
(If you want extra flavor without complicating things)
Salt & black pepper
Fresh parsley (chopped)
Splash of soy sauce (adds umami depth)
Sprinkle of thyme
Serving Ideas
These mushrooms go perfectly with:
Grilled steak
Roast chicken
Mashed potatoes
Pasta or egg noodles
Toasted bread (for dipping!)
Tips
Don’t add water — mushrooms release their own juices.
For deeper flavor, cook uncovered for the last 20 minutes.
Use cremini mushrooms for a richer, more “steakhouse” taste.
