Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
-
1 pound button mushrooms, stems removed
-
1 cup ricotta cheese
-
½ cup cooked spinach, drained and chopped
-
¼ cup grated Parmesan cheese
-
1 teaspoon garlic powder
Directions
-
I start by mixing the ricotta, chopped spinach, grated Parmesan, and garlic powder in a bowl until everything is well combined.
-
I then stuff each mushroom cap with a spoonful of the ricotta-spinach mixture.
-
Next, I arrange the stuffed mushrooms in a single layer inside my crockpot.

I cover and cook them on low for 3 to 4 hours, until the mushrooms are tender and the filling is heated through.
-
Right before serving, I sprinkle a bit of extra Parmesan on top for that final touch.
Servings and timing
This recipe makes about 20 to 24 stuffed mushrooms, which serves 6 to 8 people as an appetizer.
Cook time: 3–4 hours on low
Prep time: 10 minutes
Total time: Approximately 3 hours and 10 minutes
Variations
I sometimes swap out the ricotta for cream cheese or goat cheese for a tangier twist. For a bit of a kick, I add crushed red pepper flakes to the filling. Want more texture? I mix in some finely chopped walnuts. I’ve also tried it with chopped artichoke hearts or sun-dried tomatoes for a Mediterranean flair.
Storage/Reheating
If I have leftovers, I store them in an airtight container in the fridge for up to 3 days. To reheat, I place them in a baking dish and warm them in the oven at 350°F for about 10–15 minutes, or until heated through. I avoid microwaving them because it can make the mushrooms a bit soggy.

FAQs
How do I keep the mushrooms from getting soggy?
I make sure to drain the spinach well and avoid overfilling the crockpot. A single layer works best to keep everything tender but not watery.
Can I make these stuffed mushrooms ahead of time?
Yes, I often prepare the filling and stuff the mushrooms the night before. I store them covered in the fridge and cook them in the crockpot the next day.
Do I need to grease the crockpot?
I don’t usually need to, but if I’m worried about sticking, I give it a quick spray with nonstick cooking spray before adding the mushrooms.
Can I freeze these stuffed mushrooms?
I don’t recommend freezing them after cooking, as the texture of the mushrooms changes. However, I’ve frozen them before cooking with decent results.
What can I serve these with?
I like serving them with a fresh salad or other small bites like crostini, olives, or a cheese platter.
Conclusion
These slow cooker spinach and ricotta stuffed mushrooms are one of my go-to appetizers for gatherings or easy weeknight snacks. The creamy filling, tender mushrooms, and hands-off cooking method make them a winner every time. I just prep, stuff, and let the slow cooker handle the rest.
