These low carb 4-ingredient spinach mushroom bakes are the kind of easy little appetizer that disappears fast at potlucks, holiday tables, and casual neighborhood get-togethers. They turn simple mushrooms, spinach, cream cheese, and shredded mozzarella into a warm, creamy bite with plenty of savory flavor, and they feel just a little special without asking much from the cook.
Serve these hot from the oven with a simple veggie tray, grilled chicken, or a crisp green salad if you want to turn them into a light lunch. They also fit right in on an appetizer spread with meatballs, deviled eggs, and toothpicks nearby, and a sparkling water, iced tea, or dry white wine pairs nicely with their rich, cheesy filling.
Low Carb 4-Ingredient Spinach Mushroom Bakes
Servings: 6
Ingredients
16 large button mushrooms, stems removed
Directions
1. Preheat the oven to 375°F and lightly grease a ceramic baking dish or line a sheet pan with parchment paper. Gently wipe the mushrooms clean, remove the stems, and arrange the caps hollow-side up.
2. In a medium bowl, stir together the cream cheese, chopped spinach, and half of the mozzarella until the mixture is creamy and evenly combined.
3. Spoon the filling generously into each mushroom cap, pressing it in slightly so it stays mounded on top. Sprinkle the remaining mozzarella over the stuffed mushrooms.
4. Bake for 20 to 25 minutes, until the mushrooms are tender and the tops are bubbling and lightly golden. Let them cool for 5 minutes before serving warm.
Variations & Tips
For picky eaters: If someone in the family is unsure about spinach, chop it very finely so it blends right into the cream cheese. A little extra mozzarella on top also helps make these feel extra familiar and kid-friendly.
Make-ahead tip: You can fill the mushrooms several hours ahead and keep them covered in the refrigerator. When it is time to bake, set the dish out while the oven preheats so they cook more evenly.
Avoid watery mushrooms: Be sure the spinach is squeezed very dry before mixing it into the filling. If the mushrooms are especially large, you can also bake the empty caps for 5 minutes first, then drain off any liquid before stuffing.
Easy add-ins: If you do not mind going beyond four ingredients, a little garlic powder, grated Parmesan, or finely chopped cooked bacon can add even more savory flavor. These are easy ways to dress them up for a party platter.
