About a year ago my husband discovered that he loves mushrooms. Not only does this shock his mother, but it also floors me because he has always been very particular about what he eats. I myself am not a fan of raw mushrooms, but I do enjoy them cooked into things.

We have been on a kick recently to cut back on the amount of meat we eat and consume more vegetarian food. I have been trying to use hearty ingredients so that my family does not feel like they are missing out on meat.

My husband suggested stuffed mushrooms. I thought it sounded tedious to stuff all those little individual mushrooms, but then I realized I could use BIG mushrooms. I saw portobello mushrooms in the store and thought they were the perfect type of this recipe.

These ricotta stuffed mushrooms have become a family favorite.

Stuffed Mushroom Cooking Instructions

There are four basic steps for this meatless recipe:

  1. Clean and prep the mushrooms
  2. Prepare the cheese filling
  3. Stuff the mushroom caps
  4. Bake

How to Prepare Portobello Mushroom Tops

Portobellos need to have the stem and gills removed. The stems can be chopped up and cooked in the stuffing. Omit if you do not want the woody taste of the stem.

Remove the gills with a regular spoon. A gentle scrap is all it takes. Discard the gills.

You do not need to wash these mushrooms. Just wipe the outside with a damp paper towel.

When I first make this recipe, I made the mistake of washing my mushroom caps. This resulted in soggy mushrooms baked in a lot of liquid.

The remaining steps

Heat up a cast-iron skillet on the stovetop. Saute the chopped mushroom stems and garlic until they start to soften. Add the spinach and cook until thoroughly wilted.

Combine the pan-fried vegetables in a bowl with the ricotta cheese.

Divide the filling between the caps and place in the cast-iron skillet with the filling side up. Top with freshly grated parmesan cheese.

Place the prepared skillet in the oven to bake.

Mushrooms Stuffed with Ricotta Q&A

Do I have to make this recipe in a cast-iron skillet?

No. The vegetables can be sauteed in any skillet and then be baked in an oven-safe dish.

Can I use a different cheese for this recipe?

Fresh goat cheese can be substituted for the ricotta cheese in this recipe. The tangy taste of parmesan cheese can be subbed out with similar Italian cheeses such as Grana Padano, Pecorino Romano, or Parmigiano Reggiano.

What other vegetable can I add to the filling?

Chopped onion is a great addition to the saute. Sundried tomatoes will add a sweet and tangy flavor to the filling.

My favorite part is the stuffing. It is such a tasty combination of cheese and garlic, along with spinach!

I want to cut back on the amount of meat we eat. My family will not mind if I continue to make delicious dishes like this.

I’d like to clear up a common misconception. Mushrooms do not “soak up” water when they’re washed. Think about it. What happens to a sponge when you soak it in water? It grows. Do mushrooms do this? No. Raw mushrooms, like many vegetables, are full of water, and, when they’re cooked, they shed this water. If you’ve ever sautéed zuccchini, you know what I’m talking about. The trick is to sauté or broil your mushrooms before filling them. They’ll shrink as they give off water, and they’ll also brown and caramelize if you let them go far enough, which gives them that awesome flavor. Alton Brown disputed the “mushroom soaking up water” myth many years ago. Apparently, y’all were sleeping.

Honestly, I don't know much about mushrooms. I never ate them as a kid and only started loving them in the past 10 years or so. I need to do better research. Thanks for the info!

Yum! I love mushrooms. I'm a vegetarian so I use portabello mushrooms occasionally. I've made them in veggie lasagna, but that was kind of a full day event so that's the end of that dish for me! Every now and then I'll spot a portabello mushroom burger when I go out to eat and order it because it's a huge treat. I should probably buy them more often, but I find for most of the foods I make, regular white mushrooms are good enough. And then I did something 2 days ago that I rarely do - I bought a can of mushrooms.

I purchase mushrooms nearly every week. I used to avoid them!

When you make stuffed mushrooms you removes the stems and some of the inside to make room for your filling. Place the mushrooms upside down on a baking tray and sprinkle with a little salt and bake for about 10 minutes. This releases the water. It is very similar to eggplant prep. Then you fill them and complete the baking or transfer them to your cast iron.

Never wash mushrooms----they will soak up water very fast. Clean them with a damp cloth. Never wash!!!!!!!! That's why your dish will be watery

I made this dish last night, it was WONDERFUL! I used the large portabello mushrooms. I found that they didnt have too much of a stem but it still turned out delish. I also agree with the mushrooms do get very watery. Put them in the oven for a few minutes to dry them out as much as possible. I cooked wild long grain rice to go make a full meal!
