How to Make 2-Ingredient Crockpot Mushrooms and Butter
Step 1: Clean the Mushrooms
Gently wipe the mushrooms with a damp paper towel to remove dirt. Avoid soaking them in water, as mushrooms absorb moisture easily.
Step 2: Add to Crockpot
Place the cleaned mushrooms into the slow cooker. Scatter the butter pieces evenly over the top.
Step 3: Cook Low and Slow
Cover and cook:
- Low: 4–5 hours
- High: 2–3 hours
The mushrooms will release their own juices and cook down into a rich, buttery sauce.
Step 4: Stir and Serve
Stir gently before serving. Season with salt and pepper if desired.
