Ingredients You’ll Need

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Here’s what you’ll need to get started:

4 large portobello mushroom caps, cleaned and stems removed
1 tbsp olive oil, for brushing
1 lb Italian sausage (pork or turkey), casings removed
½ onion, finely chopped
2 cloves garlic, minced
½ tsp dried oregano
½ tsp dried basil
Salt and pepper, to taste
½ cup grated Parmesan cheese

You can easily find all of these ingredients at your local grocery store. Don’t be afraid to mix it up—try spicy sausage for an extra kick or go with turkey for a leaner option.

Let’s Get Started

Ready to bring these babies to life? Follow these step-by-step instructions to make the ultimate sausage stuffed portobellos:

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or foil for easy cleanup.
Prep the mushrooms: Gently clean the portobello caps using a damp paper towel. Remove the stems and scrape out the dark gills using a spoon. Brush both sides of each cap with olive oil and place them gill-side up on the baking sheet.
Bake the mushrooms for about 10 minutes to soften them and release excess moisture. Once done, gently blot any liquid from the caps with paper towels.
Cook the sausage filling: In a large skillet over medium heat, cook the sausage, breaking it up with a spatula. Once it begins to brown, add the chopped onion and garlic. Sauté until the sausage is fully cooked and the onions are translucent—about 6–8 minutes.
Add herbs and seasoning: Stir in the oregano, basil, salt, and pepper. Let the mixture simmer for another minute, then remove from heat. Stir in the grated Parmesan cheese.
Stuff the mushrooms: Spoon the sausage mixture into each mushroom cap, dividing evenly. Top each with shredded mozzarella cheese.
Bake again: Return the stuffed mushrooms to the oven and bake for another 10–12 minutes, or until the cheese is melted and bubbly with golden spots.
Garnish and serve: Sprinkle chopped fresh parsley over the top for a pop of color and freshness.

That’s it! Crispy, cheesy, and meaty mushrooms are ready to enjoy.

Servings and Pairing

This recipe makes 4 stuffed mushrooms, which can serve:

Storage Tips

Got leftovers? No problem—these reheat like a dream!

Refrigerate: Store in an airtight container for up to 3–4 days.
Freeze: Wrap individually and freeze for up to 1 month. Just note the texture may be a bit softer once thawed.
Reheat: Warm in the oven at 350°F (175°C) for about 10–12 minutes or in the microwave for 1–2 minutes. If microwaving, cover loosely to prevent cheese from drying out.

These make a great lunch the next day, too!

FAQs

Can I make these ahead of time?
Yes! You can prep the filling and stuff the mushrooms ahead of time, then refrigerate them for up to 24 hours before baking.

Do I need to pre-bake the mushrooms?
Yes, pre-baking helps remove excess moisture so you don’t end up with soggy mushrooms.

Can I grill the mushrooms instead of baking?
Absolutely. Grill the mushrooms for 5–6 minutes on each side before stuffing, then place them under a broiler or return to the grill to melt the cheese.

What’s the best way to clean portobello mushrooms?
Use a damp paper towel to gently wipe the surface. Avoid soaking them in water, as mushrooms absorb moisture and may become soggy.

Is this recipe keto-friendly?
Yes, this is a great low-carb, keto-friendly recipe—just double-check your sausage and cheese ingredients for added sugars or carbs.
