Portabella Pizzettas: Bite-Sized Bliss

There’s a certain magic that happens when earthy mushrooms meet the vibrant flavors of pizza. I remember as a kid, my grandma used to make something similar with large portabellas; she’d call them “mushroom boats.” The savory aroma would fill her tiny kitchen, and the anticipation was almost unbearable. We would all gather around the table, ready to devour these juicy, flavorful treats. Each bite was an explosion of textures and tastes—the meaty mushroom, the tangy tomato, the melty cheese. This pizzetta recipe is my homage to those cherished memories, a delightful appetizer that brings back the comforting warmth of my grandma’s kitchen.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 12 minutes (baking) or 3-4 minutes (broiling)
• Total Time: 27 minutes
• Servings: 12 portabella mushrooms
• Yield: 48 appetizers (approximate)
• Dietary Type: Vegetarian (can be made vegan with cheese substitution)

Ingredients

• 5 ounces frozen chopped spinach
• 1 1/2 cups shredded mozzarella cheese
• 1 teaspoon dried basil, crushed
• 1/4 teaspoon fresh coarse ground black pepper
• 12 portabella mushrooms (3 to 4 inches in diameter)
• 2 medium tomatoes, large dice
• 2 tablespoons butter or 2 tablespoons margarine, melted
• Salt

Equipment Needed

• Mixing bowl
• Cookie sheet
• Broiler pan (optional)
• Knife
• Cutting board

Instructions

1. Begin by preparing the spinach. Thaw the 5 ounces of frozen chopped spinach thoroughly. Once thawed, it’s crucial to remove as much liquid as possible. Press the spinach between paper towels or squeeze it with your hands until it’s relatively dry. Finely chop the drained spinach.

2. In a medium-sized mixing bowl, create the spinach mixture. Combine the finely chopped spinach with 1 1/2 cups of shredded mozzarella cheese, 1 teaspoon of crushed dried basil, and 1/4 teaspoon of fresh coarse ground black pepper. Mix well to ensure all ingredients are evenly distributed.

3. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This temperature will gently cook the mushrooms and melt the cheese to perfection.

4. Prepare the mushrooms. Gently clean the 12 portabella mushrooms, removing any dirt or debris with a damp cloth or paper towel. Carefully remove the stems; you can discard them or save them for another use, such as adding them to vegetable stock.

5. Prepare the baking sheet. Lightly grease a cookie sheet to prevent the mushrooms from sticking.

6. Place the mushroom caps, top side down, on the prepared cookie sheet. This allows the mushrooms to release their moisture during cooking.

7. Brush the inside of each mushroom cap with the melted butter or margarine. This adds richness and flavor to the mushrooms, and helps them to brown nicely. Use all 2 tablespoons evenly.

8. Spoon about 2 tablespoons of the spinach mixture into each mushroom cap, pressing it down lightly. Ensure each mushroom is evenly filled with the mixture.

9. Sprinkle the diced tomatoes over the spinach mixture in each mushroom cap. Season lightly with salt to taste.

10. Bake the pizzettas in the preheated oven for 12 minutes, or until the mushrooms are tender and the cheese is melted and bubbly. Alternatively, for a quicker cooking method, place the pizzettas on the unheated rack of a broiler pan and broil 4 inches from the heat for 3 to 4 minutes, watching carefully to prevent burning.

11. Once cooked, remove the portabella pizzettas from the oven or broiler. Let them cool slightly before cutting each mushroom into quarters.

12. Serve immediately and enjoy!

Expert Tips & Tricks

• Pre-cook the mushrooms slightly: If you prefer a less juicy mushroom, you can pre-cook them for 5 minutes before adding the toppings. This will release some of their moisture.
• Add a balsamic glaze: Drizzle a balsamic glaze over the cooked pizzettas for a touch of sweetness and acidity that complements the earthy mushrooms.
• Make it spicy: Add a pinch of red pepper flakes to the spinach mixture for a little heat.
• For vegan option: Use a vegan mozzarella alternative.
• Prep ahead: The spinach mixture can be prepared a day in advance and stored in the refrigerator. You can also clean and stem the mushrooms ahead of time. Assemble just before baking.

Serving & Storage Suggestions

Serve these portabella pizzettas immediately as an appetizer or snack. They’re best enjoyed warm, when the cheese is still melted and the mushrooms are tender. For a more substantial meal, serve them alongside a fresh salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake them in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for about 5-7 minutes, or until heated through. You can also reheat them in a microwave, but the texture may be slightly softer. These are not recommended for freezing after they have been baked.

FAQs (Frequently Asked Questions)
