Creamy Polenta Roasted Mushrooms

The first time I made polenta, I stood at the stove stirring for forty minutes straight, my arm aching, wondering if Italians had discovered some secret to effortless creaminess that I had missed. Then my grandmother visited, watched me struggle, and casually mentioned that the right cornmeal makes all the difference. She was right, and now this dish has become my go-to when I need something that feels like a hug but still looks impressive enough for dinner guests.

Last winter, during that relentless snowstorm that kept us inside for three days straight, I made this for my neighbors who had lost power. We ate by candlelight, huddled around my dining table, and something about the warmth of those bowls made the whole situation feel almost cozy instead of stressful. Now every time I smell roasting mushrooms, I think about how food can turn a crisis into a memory.

Ingredients

• Coarse cornmeal (polenta): The coarse grind gives you that satisfying texture that still feels luxurious, unlike instant polenta which can turn gummy
• Vegetable broth: Using broth instead of water adds layers of flavor that make the polenta taste substantial rather than bland
• Whole milk: This creates that restaurant style creaminess without needing excessive stirring or attention
• Unsalted butter: Room temperature butter melts into the polenta beautifully, creating those velvety swirls
• Parmesan cheese: Freshly grated makes a huge difference here, it melts into the polenta while creating these salty pockets of flavor
• Mixed mushrooms: The variety matters, each type brings something different to the final dish
• Fresh thyme: This herb bridges the earthiness of mushrooms with the richness of the polenta

Instructions

Get the oven going:

Crank that oven to 425°F (220°C) and position a rack in the middle, you want good air circulation for those mushrooms to get properly golden and crisp at the edges

Prep the mushrooms:

In a large bowl, toss your sliced mushrooms with olive oil, minced garlic, thyme, salt, and pepper until every piece is coated and glistening

Roast until golden:

Spread the mushrooms on a baking sheet and roast for 20 to 25 minutes, but definitely pause halfway through to give them a stir and redistribute any pooling oil

Start the polenta base:

While the mushrooms roast, bring your vegetable broth and milk to a gentle simmer in a large saucepan, watching carefully so it does not boil over

Add the polenta:

Gradually whisk in the cornmeal, pouring it slowly in a steady stream to prevent clumping, then reduce heat to low

Cook to creaminess:

Let it bubble gently for about 20 minutes, stirring often enough that nothing sticks to the bottom, until the polenta has thickened and loses that raw corn taste

Finish with richness:

Stir in the butter, Parmesan, salt, and pepper, then taste and adjust because this is your last chance to perfect the seasoning before serving

Assemble and serve:

Divide the creamy polenta among bowls, pile those roasted mushrooms on top, and finish with fresh parsley and maybe a bit more Parmesan if you are feeling indulgent

This recipe became my daughters favorite comfort food during her first semester of college. She would call home late at night after studying, describing how she made it in her tiny dorm kitchen, and somehow those conversations made the distance feel smaller. Now whenever I visit, she demands this for our first dinner together, and watching her cook it with more confidence than I had at her age feels like its own kind of reward.

Make It Your Own

The beauty of this dish lies in its adaptability. Sometimes I will sauté some spinach or kale and layer it between the polenta and mushrooms for extra color and nutrition, or top everything with a fried egg when I want to turn it into a hearty breakfast. My brother adds crumbled Italian sausage for a meatier version, and I have even seen people use it as a bed for short ribs or braised lamb shanks when they want something more celebratory.

Pairing Ideas

A light Pinot Noir or Chianti cuts through the richness beautifully, though I have also served this with crisp white wines like Sauvignon Blanc during summer. If you are avoiding alcohol, a sparkling water with lemon works surprisingly well to cleanse the palate between bites. For a complete meal, a simple arugula salad dressed with lemon vinaigrette provides the perfect bright contrast to all that creamy comfort.

Storage and Reheating

The polenta keeps remarkably well in the refrigerator for up to four days, though it will firm into a solid block that can be sliced and pan fried for breakfast polenta cakes topped with a fried egg. The mushrooms are best eaten the same day but can be reheated in a hot skillet to regain some of their crisp texture. When reheating the polenta, always add a splash of liquid and warm it slowly over medium heat, stirring constantly to bring back that creamy consistency.

• Never reheat polenta in the microwave, it creates a weird rubbery texture that no amount of stirring can fix
• If you know you are meal prepping, slightly undercook the polenta since it will continue cooking when you reheat it later
• The mushroom topping can be frozen for up to a month and reheated in a hot oven at 400°F for 10 minutes

I hope this becomes one of those recipes you turn to again and again, adapting it to whatever season or mood you find yourself in.
