Ingredients
• 8 very large, firm portobello mushrooms, about 3 inches / 7.5 cm across
• 3 Tbs / 45 g butter
• 1 medium eggplant, about 1 lb / 450 g
• 1 tsp / 5 g salt, plus more to taste
• 1 medium red bell pepper
• 2 Tbs / 30 ml olive oil
• ½ tsp / 1 g ground cumin
• 1 tsp / 2 g paprika
• 3 large cloves garlic, minced
• 3 Tbs / 45 ml white wine vinegar
• 3 Tbs / 45 g tomato paste
• 2½ Tbs / 25 g minced red onion
• ½ cup / 60 g chopped walnuts
• ¼ tsp / 0.5 g dried oregano
• Freshly ground black pepper, to taste
• 1 cup / 113 g grated Monterey Jack cheese, divided
Instructions
1. Prepare the Mushrooms: Gently wipe the mushrooms clean and snap off the stems. Using a small spoon, carefully scrape out the dark gills to create a well for the filling, leaving a sturdy shell. In a large skillet over medium heat, melt the butter. Sauté the mushroom caps for 2-3 minutes per side until lightly golden. Remove from the skillet and arrange them hollow-side-up in a lightly buttered baking dish.
2. Prep the Eggplant: Peel the eggplant and dice it into small, ½-inch / 1.25 cm pieces. Place the diced eggplant in a colander, toss with 1 teaspoon of salt, and let it sit for 30 minutes to draw out excess moisture and bitterness.
3. Sauté the Aromatics: In the same skillet, heat the olive oil over medium heat. Add the minced garlic, cumin, and paprika, and cook for about 30 seconds until fragrant.
4. Cook the Filling: Thoroughly rinse the salted eggplant under cold water and pat it completely dry with paper towels. Finely dice the red bell pepper. Add the dried eggplant and diced pepper to the skillet. Sauté for 8-10 minutes, stirring occasionally, until the vegetables are tender.
5. Finish the Filling: Stir in the tomato paste, white wine vinegar, minced red onion, and chopped walnuts. Cook for another 2 minutes until the paste has deepened in color. Season with oregano, and add salt and black pepper to your taste. Remove the skillet from the heat and stir in ½ cup / 56g of the grated cheese until melted.
6. Stuff and Top: Generously spoon the eggplant filling into each prepared mushroom cap, mounding it slightly on top. Sprinkle the remaining ½ cup / 57g of cheese evenly over the filled mushrooms.
7. Bake to Perfection: Bake in a preheated oven at 350°F / 175°C for 25-30 minutes. The mushrooms should be tender, and the cheese on top should be melted, bubbly, and golden brown.
8. Serve and Enjoy: Let the mushrooms rest for a few minutes before serving. They are fantastic on their own or paired with a side of Spinach and Dill Rice.

Pro Tips
• Salting the eggplant is a crucial step. It not only removes bitterness but also prevents the filling from becoming watery. Don’t skip it!
• For a no-waste flavor boost, finely chop the reserved mushroom stems and sauté them along with the eggplant and red pepper.
• Feel free to swap the Monterey Jack with other good melting cheeses like Gruyère, provolone, or a sharp white cheddar for a different flavor profile.
• To make this recipe vegan, use a plant-based butter and your favorite dairy-free melting cheese.
FAQ
Q: Can I make this stuffed mushroom recipe vegan
A: Absolutely. To make this recipe fully vegan, simply use a plant-based butter for sautéing and swap the Monterey Jack for your favorite dairy-free melting cheese. The rich flavors of the eggplant, walnuts, and spices will still shine through.
Q: Is there a nut-free alternative for the walnuts
A: Yes, for a delicious nut-free version, you can substitute the walnuts with an equal amount of roasted sunflower seeds or pepitas (pumpkin seeds). This will provide a similar savory crunch to the filling.
Q: How should I store and reheat leftover stuffed mushrooms
A: Store leftovers in an airtight container in the refrigerator for up to 3 days. For the best results, reheat them in an oven or toaster oven at 350°F / 175°C for 10-15 minutes, until the filling is hot and the cheese is re-melted and bubbly.
Q: Are these stuffed mushrooms a good source of vegetarian protein
A: Yes, they are a great source of plant-forward protein. Each serving packs about 15g of protein, thanks to the combination of hearty portobello mushrooms, protein-rich walnuts, and Monterey Jack cheese, making it a satisfying main course.
