These stuffed portobello mushrooms are a solid low-carb dinner that genuinely delivers on protein β each serving packs around 38g from lean ground turkey, with a savory spinach and herb filling that makes them feel far more satisfying than a typical “lighter” meal. The mushroom caps act as a natural vessel, so there’s no pastry or bread required, keeping net carbs low without any substitution tricks. They come together in about 35 minutes and hold up well in the fridge, making them a practical choice for meal prep too.

Instructions
- Preheat your oven to 200Β°C (400Β°F) and line a baking sheet with parchment paper.
- Brush both sides of each portobello cap lightly with olive oil, place them gill-side up on the baking sheet, and roast for 8 minutes to release excess moisture. Remove from the oven and pat dry with paper towels.
- While the mushrooms pre-roast, heat the olive oil in a large skillet over medium-high heat. Add the diced onion and cook for 3 minutes until softened.
- Add the minced garlic and cook for 30 seconds until fragrant, then add the ground turkey. Break it apart and cook for 5β6 minutes until fully browned with no pink remaining.
- Stir in the tomato paste, oregano, smoked paprika, salt, and pepper, then add the chopped spinach. Cook for 2 minutes, stirring, until the spinach is fully wilted and any excess liquid has evaporated.
- Divide the turkey and spinach filling evenly among the four mushroom caps, pressing it gently to mound it slightly.
- Combine the shredded mozzarella and Parmesan, then sprinkle the cheese mixture evenly over each stuffed cap.
- Return the baking sheet to the oven and bake for 10β12 minutes until the cheese is melted and golden at the edges. Serve immediately.
