Oyster Mushroom Thyme Polenta

Creamy soft polenta topped with tender garlic-sautéed oyster mushrooms, fresh thyme leaves and a light sprinkle of Parmesan cheese.

Ingredients

  • 150 g polenta (coarse cornmeal)
  • 600 ml water
  • 200 ml low-fat milk
  • 300 g oyster mushrooms
  • 2 cloves garlic
  • 1 tbsp olive oil
  • 4 sprigs fresh thyme
  • 30 g Parmesan (finely grated)
  • Salt and pepper to taste

Instructions

  1. Bring water and milk to a boil in a medium saucepan.
  2. Slowly whisk in polenta while stirring constantly to avoid lumps.
  3. Reduce heat to low and cook for 20-25 minutes, stirring frequently until soft and creamy.
  4. Tear oyster mushrooms into bite-sized pieces.
  5. Heat olive oil in a large skillet over medium-high heat.
  6. Add mushrooms and sauté for 5-6 minutes until golden and tender.
  7. Mince garlic, add to mushrooms and cook for 1 minute until fragrant.
  8. Strip thyme leaves from stems and add most to the mushrooms.
  9. Season mushrooms with salt and pepper.
  10. Divide polenta between two bowls and top with sautéed mushrooms.
  11. Sprinkle with Parmesan and remaining fresh thyme leaves.

Notes

  • Stir the polenta frequently to prevent sticking to the bottom.
  • Use instant polenta for a quicker 5-minute version if short on time.
  • The mushrooms should have nice golden edges for best flavour.

Variations

  • Mushroom Mix: Add cremini or shiitake mushrooms alongside the oyster mushrooms.
  • Cheesy Polenta: Stir 20 g Parmesan directly into the polenta for extra creaminess.
  • Greens Addition: Add a handful of baby spinach to the mushrooms in the last minute of cooking.
  • Egg Topped: Serve with a poached or soft-boiled egg on top for extra protein.
  • Herb Swap: Replace thyme with fresh rosemary or sage.

Why This Meal Is Good for You

Oyster mushrooms are a remarkable ingredient for long-term health. They contain beta-glucans, which support immune function and have shown potential in cancer prevention research. They are one of the few non-animal sources of Vitamin D, which supports bone health, mood regulation and immune resilience. Their niacin content supports healthy skin and cellular repair.

Polenta made from coarse cornmeal has a moderate glycaemic response compared to refined grains, especially when paired with protein and fat as in this dish. The combination slows glucose absorption and avoids blood sugar spikes.

Garlic provides allicin, a well-studied compound with anti-inflammatory and cardiovascular protective properties. Regular consumption is linked to reduced risk of certain cancers and improved cholesterol profiles.

Olive oil supplies monounsaturated fats and Vitamin E, both of which support skin elasticity and reduce oxidative stress associated with ageing.

The overall dish is light on saturated fat, rich in plant-based fibre and provides a solid protein foundation from mushrooms, milk and Parmesan — making it a satisfying meal that supports stable energy levels throughout the evening.
