How to Cook Portobello Mushroom in the Oven?
Portobello mushroom is pretty quick and easy to prepare. These mushrooms are the best when marinated and then baked.
Ingredients
- Two large Portobello mushrooms
- 1/2 tbsp. olive oil
- 2 tbsp. soy sauce, you can also substitute with tamari or coconut aminos
- 1/2 tsp. minced garlic
- 1/4 tsp. minced or grated ginger root
- 1 tbsp. balsamic vinegar
You can also use salt, cayenne pepper, thyme, rosemary, maple syrup, and crushed garlic.
Method
- Clean Your Portobello Mushrooms
Wipe the mushrooms with a clean, damp kitchen towel. You can use a mushroom cleaning brush to get rid of stubborn dirt. Scrub the cap and gills gently but be careful not to remove the gills. They add extra juiciness and enhance flavor.
Rinsing mushrooms or running them in a lot of water makes them mushier and ruins the expected results.
Start by removing the mushroom stem. You can cut it off with a knife or twist it off. Do not throw away the stem. It comes in handy when stuffing your mushrooms.
- Preheat your oven to 350 degrees Fahrenheit
- Create Your Seasoning Sauce
Take a large bowl, add all the ingredients you are using except mushrooms, and whisk them together to make a marinade sauce.
- Place your clean Portobello mushrooms on a baking tray with parchment paper.
Brush your marinade sauce onto the mushrooms, ensuring that all sides are well-coated.
Set the mushrooms aside and let them rest for 15 minutes.
- If you have some sauce left, rub it on the mushrooms before placing them in the oven.
Bake for 20 minutes until you have a nice brown color.
- Remove the mushrooms from the oven. Let them cool down before slicing and serving.
- Stuff Your Portobello Mushrooms (Optional)
If you want your mushrooms to be fuller, allow them to cool down and then stuff them with your preferred ingredients.
You can use the stems you set aside or use cheese, parmesan, or mozzarella. Toast them back in the oven for five more minutes to allow the cheese to melt.
The Secret to Making Perfect Portobello Mushrooms
Choose huge, fresh Portobello: If you cannot access big Portobello, it is advisable to double the sauce and the Portobello caps to ensure you have enough servings.
Always use parchment paper or foil to lay your mushrooms. If not, soak your baking pan immediately after cooking.
Do not slice the mushrooms straight from the oven. Let them rest a bit so that they retain the juices and flavors.
Don’t be afraid to spice up your mushrooms. Spices make them appealing and tasty.
