Sausage-Stuffed Portabella Mushrooms With Mozzarella Cheese

The first time I made these stuffed portobellos, it was a happy accident. I had leftover Italian sausage from a Sunday gravy (red sauce), a fridge full of enormous portobello mushrooms begging to be used, and a craving for something comforting. The aroma that filled my kitchen as these baked – earthy mushrooms mingling with savory sausage and melted mozzarella – transported me back to my grandmother’s kitchen, a place where simple ingredients transformed into magic. The first bite confirmed it: a flavor explosion that was both familiar and excitingly new.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 25 minutes
Total Time: 45 minutes
Servings: 8
Yield: 8 stuffed mushrooms
Dietary Type: Not specified

Ingredients

8 large portabella mushrooms (stems removed)
Olive oil
Salt
2 lbs Italian sausages (casings removed)
3 green onions (very finely chopped) or 3 minced yellow onions
2-4 teaspoons chopped fresh parsley
1 pinch dried basil or 2 teaspoons fresh basil, chopped
1 dash Tabasco sauce or 1 dash Louisiana hot sauce
1 tablespoon minced fresh garlic, to taste or 1/2 teaspoon garlic powder
2 cups garlic-flavored croutons (ground fine, measure 2 cups after grinding)
1/2 cup milk
1/2 cup grated Parmesan cheese
2 eggs, lightly beaten
Black pepper
Grated mozzarella cheese (use any amount desired)

Equipment Needed

Large skillet
Medium bowl
Wooden spoon
Food processor or blender (for grinding croutons)
Baking sheet
Pastry brush

Instructions

Preheat your oven to 350 degrees F (175 degrees C).
Prepare the portabella mushrooms: Lightly brush both sides of the portabella mushroom caps with olive oil. Sprinkle the inside lightly with salt (this is optional).
Cook the sausage: In a large skillet, brown the sausage meat with the finely chopped green onions or minced yellow onions. Crumble the sausage into very small pieces while browning. Continue cooking until the sausage is browned. Drain any excess fat from the skillet and let the sausage mixture cool slightly.
Prepare the egg mixture: In a medium bowl, beat the eggs with the milk, fresh parsley, basil, fresh garlic (or garlic powder), and Tabasco sauce (or Louisiana hot sauce) until well combined.
Add the cheese and croutons: Add in the grated Parmesan cheese and the ground croutons, starting with about 1 1/2 cups of ground croutons. You might need to add more later. Mix with a wooden spoon until combined.
Combine the sausage mixture: Add the cooked sausage and onion mixture to the bowl with the egg and crouton mixture. Mix well until everything is evenly distributed. The mixture should be wet but still firm enough to hold together. If the mixture is too soft, add a small amount more of the ground croutons at a time, just until the mixture binds together.
Season the filling: Season the sausage mixture with freshly ground black pepper to taste.
Stuff the mushrooms: Spoon the sausage mixture evenly between the portabella mushroom caps, piling it high if desired.
Bake: Place the stuffed mushrooms on a lightly greased baking sheet. Bake in the preheated oven for about 15-20 minutes, or until the mushrooms are tender and the filling is heated through.
Add the mozzarella cheese: Remove the baking sheet from the oven. Sprinkle the tops of the stuffed mushrooms generously with grated mozzarella cheese.
Return to oven: Return the baking sheet to the oven and continue baking for another 5 minutes, or until the mozzarella cheese is melted and bubbly, and perhaps even lightly browned.
Serve: Remove the baking sheet from the oven and let the stuffed mushrooms cool slightly before serving.

Expert Tips & Tricks

Grinding the croutons: The key to a good stuffed mushroom is the texture of the filling. Grind the garlic croutons as finely as possible. A food processor works best, but a blender can be used in a pinch. If you don’t have garlic-flavored croutons, you can use plain croutons and add a little extra garlic powder to the sausage mixture.
Controlling the moisture: Sausage can vary in fat content, which affects the overall moisture of the filling. If your sausage is particularly fatty, be sure to drain it very well after cooking. If the filling seems too wet even after draining, add more ground croutons until it reaches the desired consistency. The filling should hold its shape when spooned onto the mushrooms.
Doneness check: To ensure the mushrooms are fully cooked, pierce them with a fork. They should be tender and easily pierced. If they are still firm, continue baking for a few more minutes.
Spice it up: Don’t be afraid to adjust the amount of Tabasco sauce or Louisiana hot sauce to your liking. If you prefer a milder flavor, you can omit the hot sauce altogether or use a pinch of red pepper flakes instead.

Serving & Storage Suggestions

Serve these Sausage-Stuffed Portabella Mushrooms hot, as an appetizer, a side dish, or even a light meal. They pair well with a simple green salad or roasted vegetables. For a more substantial meal, serve them with a side of pasta or rice.

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) for about 10-15 minutes, or until heated through. You can also reheat them in the microwave, but the texture may be slightly softer. Freezing is not recommended, as the mushrooms tend to become watery upon thawing.
