Mushroom and Spinach Risotto

Why This Mushroom and Spinach Risotto Works

At the start, the onion, garlic, and mushrooms sit in hot butter and oil long enough to soften and brown. As they cook, the onion loses its bite, the mushrooms shrink and firm up a bit, and everything tastes deeper and a little sweeter. By the time the rice goes in, it’s getting coated in that fat, so each grain is slick and separate instead of dry and dusty.

Once the wine and then the broth start going in, the rice slowly drinks up the liquid. With steady stirring, the outside of each grain rubs against the others and some of the starch comes off into the pan. That loose starch thickens the broth around the rice, so the whole pan slowly changes from soupy to creamy while the centers of the grains stay a little firm.

Near the end, spinach only needs a short time in the hot rice to wilt and soften. Off the heat, Parmesan melts into that starchy liquid and turns it even smoother, so the rice, mushrooms, and spinach sit in a thick, silky sauce instead of a thin broth.

Mistakes To Avoid

Letting the rice cook without enough stirring makes it stick to the bottom of the pan and scorch in spots. The stuck bits burn while the rest of the rice is still firm, so the final risotto ends up with hard, bitter chunks mixed into a gummy base.

Adding all the broth at once turns the dish into more of a soup than a creamy risotto. The rice boils instead of slowly soaking up liquid, so the grains stay uneven inside—soft on the outside but chalky in the center, with a runny liquid around them.

Pouring in the Parmesan while the pan is still over the heat often makes the cheese clump and go stringy. Instead of melting smoothly into the rice, it forms rubbery blobs and leaves the risotto greasy.

Cooking the mushrooms too little before adding the rice leaves them pale and full of water. That extra liquid seeps out during the simmering, so the risotto gets watery and the mushroom pieces stay soft and spongy instead of nicely browned.
