Step‑by‑Step Instructions for Olive Garden Mushroom Delights
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) and lightly oil a baking dish to prevent sticking. While the oven heats, take a moment to clean your large mushrooms thoroughly under running water, ensuring all dirt is removed. Gently pat them dry with a paper towel and set aside, keeping the stems intact for future use or another recipe.
Step 2: Mix the Filling
In a spacious mixing bowl, combine the drained minced clams, finely minced green onion, minced garlic, and garlic salt. Pour in the melted and cooled butter, and sprinkle in the oregano. Mix the ingredients well until they form a consistent mixture, inviting a delightful aroma into your kitchen as the flavors meld together.
Step 3: Add Binders and Cheeses
Fold in the Italian-style breadcrumbs, the beaten egg, and a splash of the reserved clam juice to the mixture. Stir these in until the filling is fully combined and sticky. Finally, gently incorporate the grated Parmesan, Romano, and mozzarella cheeses, ensuring every bit of the mixture is coated in cheesy goodness.
Step 4: Stuff the Mushrooms
Now, it’s time to fill each prepared mushroom cap! Using a small spoon, carefully place about 1.5 teaspoons of the clam mixture into each mushroom, mounding it slightly for a generous filling. Ensure that the mushrooms are packed loosely enough to allow for some expansion as they bake, giving those Olive Garden Mushroom Delights a delightful, fluffy texture.
Step 5: Bake the Stuffed Mushrooms
Arrange the stuffed mushrooms in the prepared baking dish and drizzle the tops with any remaining melted butter for added flavor. Cover the dish with foil and place it in the preheated oven to bake for approximately 35-40 minutes. The mushrooms should become tender and the filling bubbling beneath the foil.
Step 6: Add the Final Touches
After 35-40 minutes, carefully remove the foil cover from the baking dish. Sprinkle the remaining mozzarella cheese generously over the stuffed mushrooms. Return the dish to the oven for an additional 5-7 minutes, allowing the cheese to melt and become bubbly, resulting in a visually appetizing golden finish.
Step 7: Garnish and Serve
Once out of the oven, let the Olive Garden Mushroom Delights cool for a few moments. Transfer them to a serving platter and garnish with fresh parsley for an elegant touch. Serve warm alongside lemon wedges, which will add a refreshing burst of flavor that complements these savory bites beautifully.
