Keto Spinach & Feta Stuffed Portobello Mushrooms

Hearty Portobello mushrooms filled with a savory blend of spinach, feta cheese, and herbs, perfect for a low-carb dinner.

Remove the stems from large Portobello mushrooms and gently scrape out some of the gills. In a skillet, sauté chopped spinach, minced garlic, and finely diced red onion in olive oil until the spinach wilts. Stir in crumbled feta and a mix of dried oregano and basil. Season with salt and pepper. Fill the mushroom caps with the spinach mixture and bake in a preheated oven at 190°C for 15-20 minutes until the mushrooms are tender. Drizzle with a little extra olive oil and serve warm.
