Ingredients

Stuffing Ingredients

4 large portobello mushrooms
1 cup chopped spinach
1 cup diced bell peppers
1/2 cup diced onion
2 cloves garlic, minced
1 cup cooked quinoa
1 cup shredded cheese (mozzarella or cheddar)
2 tbsp olive oil
1 tsp dried oregano
Salt and pepper to taste

Ensure all ingredients are fresh for the best flavor.

Cooking Steps

Prepare the Mushrooms

Preheat your oven to 375°F (190°C). Remove the stems from the portobello mushrooms and gently scrape out the gills with a spoon.

Make the Filling

In a skillet, heat olive oil over medium heat. Add the diced onion and garlic, sautéing until translucent. Stir in the bell peppers and spinach, cooking until softened.

Combine with cooked quinoa, oregano, salt, and pepper.

Stuff the Mushrooms

Fill each portobello cap generously with the vegetable and quinoa mixture. Top with shredded cheese.

Bake

Place stuffed mushrooms on a baking sheet and bake for 25 minutes, or until the mushrooms are tender and the cheese is melted and bubbly.

Let cool for a few minutes before serving.

Storage and Reheating Tips

Leftover stuffed portobello mushrooms can be stored in an airtight container in the refrigerator for up to three days. To enjoy them again, simply reheat in the oven at 350°F (175°C) for about 10-15 minutes or until warmed through. This makes them an ideal option for meal prep, allowing you to have a quick, nutritious meal at your fingertips throughout the week.

For freezing, make sure to let the stuffed mushrooms cool completely before placing them in a freezer-safe container. They can be frozen for up to three months. When ready to enjoy, thaw them overnight in the refrigerator and reheat as mentioned above. This way, you can savor the flavors of autumn anytime you wish!

Further Customization

Feel free to get creative with your stuffing! Add in chopped nuts for a crunch, or experiment with different cheeses, such as goat cheese or feta, to give your dish a unique twist. Incorporating seasonal spices like nutmeg or cinnamon can further enhance the autumn vibe and add depth to the flavor profile.

For a gluten-free version, ensure that your quinoa is labeled gluten-free and consider swapping traditional cheese for a dairy-free alternative. Not only does this allow those with dietary restrictions to join in, but it also encourages you to explore new ingredients that can make the dish just as delightful.
