How to Make Spinach and Cheese Stuffed Portobello Mushroom
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Step 2: Prepare the Mushroom Caps
Brush both sides of the mushroom caps with olive oil. Place them gill-side up on the baking sheet. Bake for about 10 minutes, or until they start to release water.

In a large skillet over medium heat, heat the remaining olive oil. Add the garlic and onion, sautéing until softened, about 3-4 minutes.

Add the spinach to the skillet. Cook until wilted, approximately 2-3 minutes. Remove the skillet from heat and let it cool slightly.
Step 5: Mix the Filling Ingredients
In a bowl, combine the sautéed spinach mixture with ricotta cheese, Parmesan cheese, salt, pepper, and nutmeg. Mix well until all ingredients are fully incorporated.
Step 6: Stuff the Mushrooms
Spoon the cheese and spinach mixture evenly into each mushroom cap. Top each with shredded mozzarella cheese.
Step 7: Bake Again

Common Mistakes to Avoid
Stuffed Portobello Mushrooms can be a culinary delight, but there are some common pitfalls to watch out for.
- Skipping the Pre-baking: Failing to pre-bake the mushroom caps can result in a soggy texture. Always bake them for about 10 minutes to allow excess moisture to escape.
- Overfilling the Caps: While it’s tempting to pack in as much filling as possible, overfilling can lead to spills and uneven cooking. Aim for a generous yet manageable amount of filling.
- Neglecting Seasoning: Under-seasoned fillings can make your dish bland. Season every layer of your stuffing, not just the mushrooms.
- Using Cold Ingredients: Cold cheese or spinach can affect the cooking time and texture. Allow ingredients to reach room temperature before mixing them into your stuffing.
- Ignoring Cheese Variations: Sticking strictly to one type of cheese can limit flavor. Experiment with different cheeses like feta or goat cheese for added richness.
