This soft polenta with mushrooms and spinach is a wonderfully comforting vegetarian dish that brings together earthy flavours and creamy textures.

By using instant polenta, you can have this wholesome, restaurant-style meal on the table in less than twenty minutes, making it a perfect choice for a busy weeknight.

Packed with iron from the fresh baby spinach and protein from the fried egg, this recipe is as nourishing as it is satisfying. The addition of salty Parmesan and a touch of butter ensures a rich finish that feels truly indulgent. This recipe conveniently makes enough polenta for two meals; simply chill the remaining portion to be sliced and grilled the following day for a quick lunch or side dish.

Ingredients for Soft Polenta with Mushrooms and Spinach

  • 150 g (about 150g ) instant polenta

  • 75 g (70g) Parmesan cheese (about 180ml grated)

  • Olive oil, for greasing and frying

  • 150 g (150g) mushrooms (just one kind or a mixture), sliced into smaller pieces, if necessary

  • 1 garlic clove, crushed

  • 150 g (150g) baby leaf spinach

  • 1 egg

  • A small knob of butter

  • Salt and freshly ground pepper, to season

In a pan, bring 725ml water to a boil with a pinch of salt. Stir with a whisk as you sprinkle the polenta into the boiling water. Let the mixture cook for 3–5 minutes, or for the time given in the packet instructions. Add extra (boiling) water if necessary, the polenta should be nice and soft. Grate in nearly all of the Parmesan. Taste and season with freshly ground pepper and more salt, if necessary.

When cooked, pour half of the polenta onto a flat plate that you’ve greased with olive oil, cover with plastic wrap and put in the fridge for tomorrow.

While the polenta cooks, sauté the mushrooms in a small splash of olive oil over a medium-high heat for around 10 minutes. Add the garlic at the end and cook briefly, then sprinkle with salt and pepper.

Remove the mushrooms from the pan and add the spinach. Stir-fry the spinach until just wilted. Remove the spinach from the pan and fry an egg (you might need to add another small splash of olive oil).

Stir the butter into the cooked polenta and spoon it into a deep plate. Arrange the mushrooms and spinach on the polenta and top with the fried egg. Season lightly with salt and pepper. Top with the rest of the Parmesan, in slices.
