Stuffed mushrooms are a quick way to quiet growling stomachs while you are getting dinner ready. For this recipe, I’ve stuffed them with spinach, sun-dried tomatoes and a little Parmesan for a rich savory flavor. Try them for a great start to Thanksgiving dinner.
To Tease the Appetite
While a little snack served before dinner is traditionally called an hors d’oeuvre, its just too hard to spell. The word appetizer has become synonymous with pre-dinner snacks and it makes more sense to me. Sounds like to tease the appetite. Just a teaser before the main course, these stuffed mushrooms are great for holidays, parties, even while watching your favorite game on TV.
When buying mushrooms to stuff, hand pick them for the perfect, uniform size. Skip the packages. You can’t always tell how fresh they are and the sizes very.
Go for about a 2″ across cap. While they look bigger than bite size, mushrooms shrink when baked. Smaller ones shrink into nothing. Buy mushrooms that have closed stems, where the gills are not exposed. That is the sign of a fresh mushroom. Also, choose mushrooms with no brown spots, that are firm, white and not shriveled.
To clean mushrooms, wipe them gently with a damp paper towel or use this trick. Hold 2-3 in cupped hands, and very quickly, briefly, run them under cold slowly running water, rubbing the mushrooms in your hands. Any debris will be loosened and rinse off. Then drain on paper towels. Pop the stems out and reserve them for the filling.
Place mushroom caps round side down on a rimmed baking sheet or casserole dish. If you use a casserole, be sure it is broiler-friendly. I once had an “oven-safe” glass dish explode from the heat of the broiler, which is why I prefer to use metal rimmed baking sheets. See my notes below under tools.
Sprinkle the caps with olive oil, salt and pepper. Broil for approximately 7-10 minutes or until the caps are golden and the mushrooms have released their juices. Discard the juices from the mushrooms.
Cook the Filling
To create a savory filling for your mushrooms, roughly chop the stems and cook in a saute pan with the rest of the ingredients. The dry sherry listed is optional. After the alcohol cooks off a lovely flavor is left. You can skip it if you prefer to cook sans-alcohol. To perfectly portion the filling in the caps, use a #100 disher or a teaspoon.
When ready to enjoy, bake and top with a little extra sprinkle of Parmesan if desired. You can make them ahead a few hours, cover and refrigerated until guests arrive, then bake and serve.
Tips on Tools
For evenly mounded and portioned stuffed mushrooms, I use a #100 disher. You can also use a teaspoon. I have dishers in many sizes, with the 100 being the smallest. They come in handy for portioning out all kinds of ingredients when cooking and baking. Find them on Amazon (follow links).
Another essential tool in my kitchen is the rimmed baking sheet. They are inexpensive and in constant use for cooking, roasting, baking, organizing, and keeping things clean. The handiest sizes are the quarter sheet and half sheet. Find them on Amazon (follow links) or at a restaurant supply or cooking store.
Stuffed Mushroom with Sun Dried Tomatoes and Spinach
Serves 4-6 as a snack or appetizer
- 16 large white mushrooms (about 2″ or 5 cm across)
- 2 1/2 tablespoons olive oil, divided
- Salt and pepper
- 1/4 cup sun-dried tomatoes, oil-packed, drained well, finely chopped
- 1 large shallot, finely chopped
- 3 garlic cloves, finely chopped
- 5-6 ounce (140-170 grams) bag baby spinach, roughly chopped
- 2 tablespoons fresh chopped oregano (sub Italian parsley or 1 teaspoon dried oregano)
- 1/2 cup + 1 tablespoon grated Parmesan
- 2 tablespoons dry sherry (optional)
- Wipe mushrooms clean with a damp paper towel. Alternatively, under slowly running water, cup 2-3 mushrooms at a time in your hands. Quickly run them under the water, gently rubbing the mushrooms to remove any debris. Place on paper towels to dry. Pop out the stems by pushing them from side to side, leaving a hollow center. Roughly chop stems or briefly pulse in a food processor.
- Pre-heat broiler. Set rack one level down from the top. Place mushrooms stem side up on a rimmed baking sheet or broiler-safe casserole in a single, flat layer. Drizzle with 1 1/2 tablespoons oil and sprinkle with salt and pepper. Broil mushrooms about 7-10 minutes (depending on your broiler) until they are browned and mushrooms are tender. When done, roll mushrooms around in the liquid, drain, and place on a clean rimmed baking sheet or in a broiler-safe casserole dish. Discard the juices.
- In a medium saute or fry pan, heat the olive oil over medium heat. Add mushroom stems and cook until any moisture evaporates and they are browned. Add shallot and cook until softened, stirring, about 1-2 minutes. Add garlic and cook 1 more minute. Add sherry and cook until almost dry. Add sun-dried tomatoes and spinach. Cook until spinach is wilted and some of the moisture ha cooked off.
- Pour filling into a bowl, stir in Parmesan. Taste filing and add a little salt and pepper.
- With a teaspoon or #100 disher, fill the center of the mushrooms, mounding filling. Pre-heat broiler. Place filled mushrooms on rimmed baking sheet or in a casserole, sprinkle with the last tablespoon of Parmesan. Broil until browned and heated through.
