Broccoli Stuffed Baby Portabella Mushrooms: A Culinary Delight

The first time I made these stuffed mushrooms, it was a chilly autumn evening. The aroma of earthy portabellas mingling with garlicky cheese and sweet roasted peppers filled my kitchen, creating a comforting and inviting atmosphere. My family devoured them so quickly, I barely had time to snag one for myself! The colorful presentation and delightful combination of flavors made them an instant hit and a recipe I’ve cherished ever since.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 15 minutes
• Total Time: 30 minutes
• Servings: 6
• Yield: 12 Mushrooms
• Dietary Type: Vegetarian

Ingredients

• 10 ounces baby portabella mushrooms or 10 ounces large button mushrooms
• 2 tablespoons butter
• 1/2 cup red onion, finely chopped
• 1 cup broccoli, finely chopped
• 1/4 cup seasoned dry bread crumb
• 5 1/4 ounces boursin spreadable cheese with garlic and herbs
• 1 tablespoon roasted red pepper, chopped

Equipment Needed

• 10-inch skillet
• Baking pan

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C). This will ensure the mushrooms cook evenly and the stuffing is heated through perfectly.

2. Prepare the mushrooms by gently removing the stems from the baby portabella mushrooms. Take care not to damage the caps. Chop 1/2 cup of the removed mushroom stems and set aside. Discard any remaining stems that exceed the 1/2 cup measurement, as too many stems can make the filling watery.

3. In a 10-inch skillet, melt 2 tablespoons of butter over medium heat. Using a skillet of this size provides enough surface area for even cooking.

4. Add the finely chopped red onion and chopped broccoli to the skillet. Cook for 2 minutes, stirring occasionally. This softens the vegetables slightly and allows their flavors to meld.

5. Stir in the chopped mushroom stems (the 1/2 cup you set aside earlier).

6. Continue cooking for another 2 minutes, stirring occasionally. The mushrooms will release some of their moisture, which will contribute to the overall moisture of the filling.

7. Remove the skillet from the heat and allow the mixture to cool slightly. This prevents the cheese from melting too quickly when you incorporate it.

8. Stir in the seasoned dry bread crumbs and the boursin spreadable cheese with garlic and herbs. Make sure everything is evenly combined so that each bite is flavorful.

9. Spoon the vegetable mixture generously into the prepared mushroom caps. Don’t be afraid to pile it high!

10. Place the stuffed mushrooms on an ungreased baking pan. An ungreased pan is sufficient as the mushrooms will release some moisture during baking.

11. Garnish each mushroom with a small piece of chopped roasted red pepper. This adds a touch of sweetness and a pop of color to the finished dish.

12. Bake in the preheated oven for 15 minutes. The mushrooms should be tender and the filling heated through. The tops will be lightly browned.

Expert Tips & Tricks

• For extra flavor: Sauté a clove of minced garlic with the onion and broccoli.
• Make-ahead option: Prepare the filling a day in advance and store it in the refrigerator. Assemble the mushrooms just before baking.
• Prevent soggy mushrooms: Pat the mushroom caps dry with a paper towel before stuffing them.
• Cheese Variation: If you cannot find Boursin, cream cheese mixed with garlic, herbs, and a pinch of salt works well as a substitute.
• Breadcrumb Tip: Panko breadcrumbs can be used for a crispier topping.

Serving & Storage Suggestions

Serve the Broccoli Stuffed Baby Portabella Mushrooms immediately after baking for the best flavor and texture. They make an excellent appetizer, side dish, or even a light vegetarian main course. Arrange them artfully on a platter for an elegant presentation.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350 degrees F (175 degrees C) until heated through, or microwave in short intervals until warmed. Note that the mushrooms may become slightly softer upon reheating. Freezing is not recommended as the mushrooms can become watery upon thawing.
