Sausage-Stuffed Cremini Mushrooms

Browned sausage, finely chopped mushroom stems, Parmesan, and panko make a savory filling that bakes neatly in dry cremini caps and reheats well for a gathering.

Sausage-stuffed cremini mushrooms sit in a shallow dish with browned crumb tops and flecks of parsley.

These stuffed mushrooms are built for a table of small bites: the sausage and chopped stems cook together, while panko catches extra moisture before the caps go into the oven.

Start with dry caps

Wipe the cremini mushrooms clean and pat them dry after removing their stems. Their open cavities make filling simple, and a dry surface helps the caps roast rather than steam in the pan.

Cook out the stem moisture

The chopped stems go into the skillet with the sausage, where they soften and release their water before the crumbs are added. Once panko absorbs the remaining fat, the filling should hold a mound without looking wet.

Cremini caps sit cavity-up on parchment beside a bowl of sausage, mushroom-stem, and crumb filling. — Sausage, softened mushroom stems, garlic, crumbs, and cheese form a cohesive filling before the caps are stuffed.

Fill without compressing

Spoon the mixture into the caps and let it sit in a small mound instead of pressing it down hard. Space between the mushrooms gives the heat room to brown the topping and lets moisture escape.

Look for tender caps and browned tops

The mushrooms are ready when a knife meets little resistance but the caps still hold their shape. A golden filling and a hot center show that the crumb topping has set without drying out the mushrooms.

Keep the bottoms dry on the way

For a potluck, let surface steam dissipate on a rack before refrigerating the mushrooms in a shallow container. Carry them chilled, then rewarm uncovered on a rack over a pan so moisture can escape instead of collecting beneath the caps.

Sausage-Stuffed Cremini Mushrooms

8 servings

60 minutes total

Ingredients

• 1 1/2 lb medium cremini mushrooms, stems reserved
• 8 oz mild Italian sausage, casings removed
• 1 tbsp olive oil
• 2 garlic cloves, finely minced
• 1/2 cup panko breadcrumbs
• 1/3 cup finely grated Parmesan cheese
• 2 tbsp chopped fresh parsley
• 1/2 tsp kosher salt
• 1/4 tsp freshly ground black pepper

Method

Heat the oven
Set a rack in the center of the oven and heat to 400 F. Line a rimmed sheet pan with parchment so the filled caps release cleanly after baking.
Look for: The oven is fully preheated and the parchment lies flat on the sheet pan.
Prepare the mushrooms
Brush or wipe the mushroom caps clean, remove the stems, and finely chop the stems. Pat the caps dry and arrange them cavity-side up on the lined pan; dry caps roast instead of pooling water.
Look for: The caps feel dry, their cavities are open, and the chopped stems are in small even pieces.
Brown the sausage and stems
Warm the olive oil in a skillet over medium heat. Add the sausage and crumble it finely; when most pink has disappeared, stir in the chopped mushroom stems and cook until the sausage reaches 160 F and the stems have softened and released their moisture.
Look for: Sausage crumbles are browned with no raw pink, and a thermometer in the mixture reads 160 F. The chopped stems are tender and the skillet is not watery.
Add the garlic
Stir the minced garlic into the hot sausage mixture and cook for about 30 seconds, just until fragrant. Take the skillet off the heat before the garlic colors or turns bitter.
Look for: The garlic smells fragrant but remains pale rather than browned.
Make the filling
Stir the panko, Parmesan, parsley, salt, and black pepper into the sausage mixture. Let the filling stand for 3 minutes so the crumbs absorb excess fat; it should hold together when pressed without looking wet.
Look for: The filling is evenly mixed and holds a light mound on a spoon without liquid collecting underneath.
Fill the caps
Spoon the filling into each mushroom cavity, dividing it evenly and forming a small mound without packing it tightly. Keep the caps in one layer with space between them so moisture can escape in the oven.
Look for: Each cavity is filled to the rim with a loose, lightly mounded top, and no cap is stacked.
Bake until hot and browned
Bake at 400 F for 18 to 22 minutes, rotating the pan once, until the caps are tender but still hold their shape, the filling tops are browned, and the centers reach 165 F.
Look for: The caps yield to a paring knife without collapsing, the filling has golden edges, and a center reads 165 F.
Rest and serve warm
Let the mushrooms stand on the pan for 5 minutes so the filling sets and the caps are easier to lift. Serve warm, arranging them in a shallow dish so their crisp tops stay exposed.
Look for: The filling stays in the caps when lifted, and the tops remain dry and lightly crisp.
Pack and rewarm for a potluck
For transport, cool the mushrooms in one layer on a rack only until surface steam dissipates, then refrigerate in a shallow lidded container and carry chilled in a cooler. At the venue, rewarm uncovered on a rack over a rimmed pan at 350 F for 8 to 12 minutes, until hot in the centers; airflow keeps the bottoms from turning soggy.
Look for: The mushrooms travel cold in a shallow layer, and rewarming uncovered lets moisture escape rather than collect under the caps.
