Mushroom Tips
Mushrooms are a healthy veggie that is easy to use in recipes with a few simple tips.
Should I wash mushrooms?
Don't wash mushrooms with water it will leave brown spots on the surface. Instead, use a dry towel, paper towel or soft-bristled brush to clean any dirt off of a mushroom.
What mushroom is best for stuffing
I like to use the small white button or baby bella mushrooms when I am stuffing them. They hold their shape well and are the perfect size for appetizers.
Should mushrooms be cooked on high heat?
When cooking mushrooms in a pan, it is best to cook them on high heat vs. low heat. Medium-high to high heat will help evaporate the liquid mushrooms give off when cooking. This will ensure they are cooked hourly and turn a nice golden brown with a concentrated flavor.
🔪 Instructions
- Preheat the oven to 375 degrees
- Remove the stems from the mushrooms and dice them finely. Place caps bottoms up in a baking dish.
- Dice the mushroom stems into very small pieces. Set aside.
- Next, add olive oil to a medium-sized pan and heat over medium-high heat. *Note, I suggest string often as you cook the veggies. Your goal is to have the moisture evaporate from the veggies when you are finished cooking the mixture.
- Next, add onions, and saute until they are transparent.
- Add garlic and chopped mushroom stems. Cook until the mushroom stems turn brown.
- Next, add spinach, and basil, occasionally stirring until stem pieces are soft and moisture has evaporated.
- Add chopped sun-dried tomatoes, salt, pepper, and chopped pecans, sauteing for 1 minute. Remove from heat.
- Stuff the mixture into mushroom caps and bake for 15 to 20 minutes in the preheated 375-degree oven. The mushroom caps should be soft and brown when finished cooking.
- Remove from oven and allow to cool for a few minutes. Then drizzle Citrus Basil Dressing over the mushrooms and top with chopped fresh basil. Serve and enjoy.

Nutrition
Are mushrooms good for you?
Mushrooms can get a bad rap in the food world, many people dislike them just because of their looks and texture. However, they are great tasting and packed with nutrition that might be surprising. Organic Facts has a great article on the benefits of adding mushrooms into your diet. Here are just a few.
Lower Blood Pressure: Studies of various types of mushrooms, including shiitake and maitake mushrooms, have shown them to be high in potassium content. Potassium acts as a vasodilator, relaxing tension in blood vessels and, therefore, reducing blood pressure.
Vitamin D: is a relatively rare vitamin to find in vegetables, and in fact, its edible forms are not particularly common. However, mushrooms have it, and this essential vitamin can facilitate the absorption and metabolism of calcium and phosphorous.
Prevent Diabetes: Mushrooms are an ideal low-energy diet for diabetics, as cited in Functional Foods in Health and Disease. They have no fats, no cholesterol, very low levels of carbohydrates, high protein content, and a wealth of vitamins and minerals. They also contain a lot of water and fiber. Moreover, they contain natural insulin and enzymes which help the breaking down of sugar or starch in food.
Suppress Breast Cancer Growth: NutritionFacts.org has a great video that shares with us why mushrooms are important for women to add to their diets. Just 5 a day can make a difference in helping suppress breast cancer cell growth. white mushrooms are cheap, convenient, and are apparently able to outsmart breast cancer cells that try to make their own estrogen by crippling the enzyme tumors use to make it.
Vegan Stuffed Mushrooms are a simple and delicious way to get more mushrooms into your diet. They make a great appetizer or if you are like me, they make a meal. I just happened to eat all the mushrooms in this picture after the photo shoot for my supper.

Where is the recipe for the citrus basil dressing?
Gina
Dawn, thank you so much for pointing out I missed the citrus basil dressing! I have updated the recipe to correct my mistake. I hope you enjoy these.
Pamela
I made these as hors d’oeuvres for a small gathering, and they were a huge hit. I didn’t have pecans but substituted with walnuts and pine nuts. They were delicious. Thanks for the great recipe!
Gina
Oh Pamela, what a good idea to substitute with walnuts and pine nuts. Thanks for taking the time to let me know!
Marilyn
I am assuming I need to cook the mushrooms caps but your instructions are not clear? 400 degrees for how long? I have read that baking the caps before stuffing them?
Nikki Black
Step 3 says to cook them for 15 minutes.
Rich
Hi, In the Top Tips section it states Cook the mushrooms at a high temperature such as 400 degrees. But the actual instructions say pre heat the oven to 325 degrees. Can you clarify, thank you.
Gina Dickson
Rich, you are absolutely right. This is very confusing. I just went in and corrected some things to clarify that mushrooms need to be cooked at a relatively high heat to evaporate the moisture as they cook.
