Tasty Olive Garden Stuffed Mushrooms

Here’s my take on those famous Olive Garden stuffed mushrooms, with a rich filling made of Italian cheeses, fresh herbs, and garlic, all topped with that signature buttery breadcrumb crust.

These stuffed mushrooms are always the first appetizer to disappear when I serve them at dinner parties. I usually make an extra batch to keep in the fridge because my family loves snacking on them the next day. Nothing beats having restaurant-style appetizers right at home, right?

What Kind of Mushrooms Should I Use?

For stuffed mushrooms, white button mushrooms or baby bella (cremini) mushrooms are your best bet. Look for mushrooms that are about 2-3 inches in diameter – they’re the perfect size for appetizer portions and will hold a good amount of filling. When shopping, pick mushrooms that feel firm and have a fresh, clean appearance without any dark spots or slime. It’s best to avoid pre-sliced mushrooms since you’ll need whole caps for stuffing, and try to choose ones that are similar in size so they’ll cook evenly. Before using them, just give them a quick wipe with a damp paper towel instead of washing them under running water, since mushrooms act like little sponges and can get waterlogged.

Options for Substitutions

Need to make some changes to this mushroom recipe? Here are some handy swaps you can try:

• Large mushrooms: White button mushrooms are perfect, but you can also use cremini (baby bella) mushrooms. Just make sure they’re large enough to stuff – about 2 inches in diameter works best.
• Minced clams: If you’re not a fan of clams or can’t find them, try using finely chopped imitation crab meat, canned crab, or even finely chopped artichoke hearts for a vegetarian option.
• Mozzarella cheese: Feel free to swap mozzarella with provolone, fontina, or mild white cheddar. They’ll all melt nicely and give you that good cheese pull.
• Italian-style bread crumbs: Regular breadcrumbs work too – just add 1 teaspoon of Italian seasoning. Or try crushed crackers, panko breadcrumbs, or even crushed pork rinds for a low-carb option.
• Green onion: You can replace this with 2 tablespoons of finely minced regular onion or shallots if that’s what you have on hand.
• Parmesan cheese: Romano or Asiago cheese make good substitutes here. Just avoid pre-grated cheese if possible – freshly grated gives the best flavor and texture.

Watch Out for These Mistakes While Cooking

The biggest challenge when making stuffed mushrooms is dealing with excess moisture – make sure to thoroughly clean your mushrooms with a damp paper towel instead of washing them under running water, which can make them waterlogged and soggy. Another common mistake is overcrowding the mushrooms in the baking dish, so give them enough space to allow the heat to circulate evenly and help the tops get nicely browned. To prevent a rubbery texture, don’t skip the important step of pre-cooking the mushroom caps for 5-7 minutes before stuffing them, which helps release their natural moisture and ensures they’ll be perfectly tender when done. For the best flavor and texture, make sure your stuffing mixture isn’t too wet – if it seems too moist, add a few more bread crumbs until it holds together well but isn’t dry.

What to Serve With Stuffed Mushrooms?

Since these stuffed mushrooms are inspired by Olive Garden’s famous appetizer, they work perfectly as a starter before your favorite Italian main dishes. A simple pasta dish like fettuccine alfredo or spaghetti marinara makes an excellent follow-up to these savory bites. If you’re serving them as a main course, pair them with a fresh green salad dressed in light Italian vinaigrette and some warm, crusty bread to soak up any extra butter and herbs from the mushrooms. For a complete appetizer spread, try serving them alongside bruschetta, garlic knots, or a small charcuterie board with Italian meats and cheeses.

Storage Instructions

Keep Fresh: Got leftover stuffed mushrooms? Pop them in an airtight container and keep them in the fridge for up to 3 days. The filling might get a bit more firm in the fridge, but don’t worry – they’ll still taste great when reheated!

Make Ahead: You can prep these mushrooms a day in advance – just stuff them and keep them covered in the fridge until you’re ready to bake. This is super handy when you’re planning a dinner party or family gathering. Just add an extra minute or two to the baking time since they’ll be cold from the fridge.

Warm Up: To bring back that fresh-from-the-oven taste, pop them in the oven at 350°F for about 10-12 minutes, or until they’re heated through. You can also use the microwave for 30-45 seconds if you’re in a hurry, though they won’t be quite as crispy on top.

Ingredients

For the mushrooms:

• 12 large fresh mushrooms (stems removed and reserved)

For the filling:

• 1/2 cup Italian bread crumbs (I use Progresso Italian Style Breadcrumbs)
• 1 large egg, beaten (lightly for binding)
• 1 tbsp melted butter
• 1 can minced clams (6 oz), drained (reserve clam juice for another use)
• 2 tsp minced garlic (freshly minced for best flavor)
• 1 tsp dried oregano
• 1 finely chopped green onion (white and light green parts only)

For the topping:

• 1/4 cup shredded mozzarella cheese (finely shredded melts best)
• 3 tbsp melted butter
• 3 tbsp grated Parmesan cheese

Step 1: Prepare the Baking Environment

Preheat your oven to 350 degrees F.

While the oven is heating, spray a baking dish large enough to hold the mushrooms with non-stick cooking spray to ensure the mushrooms do not stick while baking.

Step 2: Prepare the Mushrooms

Carefully remove the stems from the mushrooms and clean each mushroom cap with a dry paper towel.

Avoid using water to clean the mushrooms, as it can cause them to become soggy.

Step 3: Make the Filling

In a mixing bowl, stir together all the ingredients for the filling.

Ensure the mixture is thoroughly combined to incorporate all the flavors evenly throughout the filling.

Step 4: Stuff the Mushrooms

Fill each mushroom cap with 1-2 spoons of the prepared filling.

Arrange the stuffed mushrooms, filling side up, on the prepared baking dish.

Depending on the size of your mushrooms, you should be able to fill between 8 to 12 mushroom caps.

Step 5: Bake the Mushrooms

Drizzle 3 tablespoons of melted butter over the stuffed mushrooms to add richness.

Cover the baking dish with foil tightly.

Place the dish in the preheated oven and bake for 20-30 minutes, or until the mushrooms are tender to your liking.

Step 6: Add Cheese and Final Bake

Carefully remove the foil from the baking dish.

Sprinkle grated mozzarella cheese over the top of each mushroom.

Return the dish to the oven and bake uncovered for an additional 2-3 minutes, or just until the cheese is melted and bubbly.

Step 7: Serve and Enjoy

Once the cheese has melted, remove the baking dish from the oven.

Allow the mushrooms to cool slightly before serving.

Enjoy your deliciously stuffed mushrooms!
