Grilled Spinach Dip-Stuffed Portabella Mushroom Caps Ingredients:

Grilled Spinach Dip-Stuffed Portabella Mushroom Caps are comprised of three components: 1. the portabella mushroom caps themselves, 2. creamy spinach dip filling, and 3. a crunchy Parmesan-panko topping.

For the mushrooms and spinach dip filling components, you'll need:

  • Portabella mushroom caps - These are the very large, flat mushroom caps you see in the produce section of the grocery store. They're typically sold in plastic-wrapped packages of two. You'll need a total of 4 mushroom caps for this recipe.

  • Extra-virgin olive oil - A light drizzle on the mushrooms moistens them for the grill.

  • Salt & pepper - Just as you would do for meats, a sprinkling before they're cooked nicely seasons the mushrooms and enhances their flavor.

  • Cream cheese -Creates the base of the spinach dip filling. We recommend sticking with full-fat cream cheese for the best texture and flavor.

  • Mayonnaise - "Loosens" the cream cheese to create a creamy spinach dip filling. Plain Greek yogurt may substituted.

  • Frozen spinach - It wouldn't be spinach dip filling without the spinach! Frozen spinach works great in the filling, both for flavor and convenience. Be sure to thaw and thoroughly drain the spinach to keep the filling from becoming too watery.

  • Dried thyme - Seasons and adds a nice, distinct earthy flavor to the filling that pairs beautifully with the mushrooms.

  • Crushed red pepper flakes - A small pinch adds a hint of spicy heat to the filling. Use sparingly so they don't overpower the filling's other flavors.

For the crunchy Parmesan-panko topping, you'll need:

  • Parmesan cheese - Shredded combines with panko bread crumbs to serve as the base of the crunchy topping. Grated Parmesan could be substituted.

  • Panko bread crumbs - Bring the crunch to the topping. Panko are Japanese-style bread crumbs that are larger and more crunchy than regular bread crumbs, and create a texture that's just not possible with regular bread crumbs. Look for Panko in canisters alongside regular bread crumbs in the grocery store.

  • Dried thyme - Seasons the crumb topping, and compliments the thyme flavor in the mushrooms' spinach dip filling.

  • Extra-virgin olive oil - Moistens the topping and helps it hold together in crumbs.

  • Salt & pepper - Seasons and enhances the crumb topping's flavor.

How to Make Grilled Spinach Dip-Stuffed Portabella Mushroom Caps:

Grilled Spinach Dip-Stuffed Portabella Mushrooms Caps are truly easy to make. Simply mix up a simple spinach dip filling, stuff the portabella mushroom caps, sprinkle with a crunchy panko topping, and grill.

Let's take a closer step-by-step look.

To get these stuffed grilled mushrooms going, start by removing the gills and stem from the big and beautiful portabella mushroom caps. I scrape the gills with a spoon, and then use a butter knife to get up under the rim.

Removing the gills accomplishes two things. It:
  1. Creates space to pack in more of the tasty spinach dip filling, and
  2. Prevents the gills from becoming mushy while cooking, leading to an unpleasant texture and (sometimes) unpleasant bitter-ish flavor.

Once the gills are removed, rub the cleaned caps inside and out with a touch of olive oil and sprinkle with a bit of salt and pepper.

Then pop those babies on the grill -- inside down -- to get them cooking.

Once the insides have cooked for about 5 minutes, flip the caps over and fill them up with creamy, cheesy, spinach dip filling. You can heap the filling on there pretty good.

Then sprinkle on a little Parmesan-panko crumb topping.

Let the stuffed portabellas hang out on the grill for about 15 minutes or so, until the mushrooms are tender and the filling is all warmed through.

  1. Love your recipe. Just want to know why you scrape inside of mushroom. Use these a lot in place of meat. Keep up good ideas. Thank you.

    1. So glad you like the recipe! You don't HAVE to scrape out the inside of the mushroom, but I do because the dark brown gills typically turn to a mushy texture when cooked and can turn to a pretty nasty color, neither of which I find appealing.
