How do I clean portobello mushrooms?

Throughout the years, I’ve met many people who are nervous about working with fresh mushrooms for the first time because they aren’t sure how to clean them. I have good news! Cleaning portobello mushrooms is a breeze. Start by removing the stems. But don’t throw them away! You can use the stems when making vegetable stock. You can add them to the compost if you don’t have a purpose for them. Place the de-stemmed mushrooms in a colander in your sink and use a low flow to spray them until dirt and excess debris are gone gently. Then lay the mushrooms on a paper towel to dry. You can also use a damp paper towel to wipe them clean. This is the best option if your sprayer isn’t very gentle. Being gentle is critical because mushrooms can break if not handled with care.

How much quinoa do I need?

That will depend on how many mushrooms you plan to stuff and how many people you need to feed. Every single cup of uncooked quinoa yields three cups of cooked quinoa. For this recipe, I use four mushrooms and two cups of quinoa. I recommend preparing your quinoa in advance so it can be brought to room temperature before mixing in with the other stuffing ingredients. 

What if I don’t have pomegranate molasses on hand? 

Not having all the ingredients for a recipe can be frustrating, but there’s no need to worry if you don’t have pomegranate molasses on hand for this recipe. You can still achieve a similar flavor by substituting it with balsamic vinegar. Balsamic vinegar’s rich, tangy flavor can provide a similar sweet and sour note that pomegranate molasses offers. Adjust the amount of balsamic vinegar to personal preference as the strength and sweetness may vary by brand. Red wine vinegar can be left out to prevent overwhelming acidity. So, use what you have in your pantry to create these delicious stuffed Portobello mushrooms!

Do you have any tips for selecting veggies?

I like using frozen artichoke hearts when making this recipe. Before cooking, I soak it in cold water and change out the water a couple of times. Then I pat the artichoke dry and chop it roughly. When it comes to spinach, I recommend working with baby spinach. Still, you can make it work if you only have access to regular spinach. Remove the stems and chop the spinach into smaller pieces. While frozen spinach isn’t ideal (it can be soggy if you don’t prepare it correctly). You can use it if you take care to remove all excess water.

How should I serve these stuffed Portobello mushrooms?

Stuffed Portobello mushrooms are protein-packed and versatile, perfect for showcasing their natural mushroom flavor in various dishes. They can stand alone as a main course without any other sides. However, you could pair them with other dishes for a more substantial meal. You could serve them with braised lamb shanks for a comforting dinner or next to Mediterranean oven-baked chicken drumstick.

Pair them with a refreshing summer zucchini or baby spinach and lentil salad for a lighter meal. The lemon zest and fresh thyme in the marinade and stuffing work together to create the perfect blend of flavors. Whatever you decide to serve with these stuffed Portobello mushrooms, make sure they are the show’s star!

Rana’s Notes!

Storage: To store the leftover stuffed Portobello mushrooms, let them cool down to room temperature, then place them in an airtight container or wrap them tightly with plastic wrap. Store the mushrooms in the refrigerator for up to 3-4 days. Reheating: To reheat the stuffed mushrooms, preheat the oven to 350°F. Remove the mushrooms from the fridge and let them come to room temperature for about 10-15 minutes. Place the mushrooms in a baking dish and cover them with foil. Bake the mushrooms for about 10-15 minutes or until heated through. Alternatively, you can reheat the mushrooms in the microwave on high for 1-2 minutes. Serve and enjoy!
