Packed full of umami, roasted mushrooms and tomatoes are coated in a fresh, fragrant Sichuan chile oil and served on top of creamy polenta in this midweek dinner hit. The oil can be made ahead, and will continue to develop in flavor. Make extra, as you’ll want to drizzle it over your eggs in the morning. Try using a variety of mushrooms — some oyster mushrooms torn into chunks, or portobellos cut into thick slices — but do make sure to slice them to the same thickness so that they cook evenly as they roast. The mixture is perched on a very simple polenta, but feel free to add butter, milk and cheese to it for a bit of extra indulgence.

Preparation

  1. Step 1

    Heat the oven to 475 degrees.

  2. Step 2

    In a small pan, heat ¼ cup of the oil and the cinnamon stick over medium-high for 5 minutes, until the oil is hot and the cinnamon stick is lightly bubbling. Add the ginger, Aleppo pepper flakes, garlic, soy sauce, cumin and Sichuan peppercorns and cook for 30 seconds, then remove from the heat and leave to marinate.

  3. Step 3

    Mix the tomatoes and 1-inch scallion pieces with 1 tablespoon of oil and ¼ teaspoon of salt and roast on a baking sheet for 20 minutes, until lightly charred. Set aside.

  4. Step 4

    While the tomatoes roast, toss the mushrooms with ½ teaspoon salt and the remaining ¼ cup oil and spread on a parchment-lined baking sheet. Set in the oven along with the tomatoes to roast for 15 minutes, turning halfway through, until lightly golden and cooked through. Set aside.

  5. Step 5

    In a medium saucepan, bring 4 ¼ cups water to a boil over high heat. Add the polenta and 1 teaspoon of salt and whisk until the mixture comes back to a boil. Turn the heat down to medium and cook for 2 minutes, whisking regularly, until the mixture has thickened. Remove from the heat and allow to sit for a few minutes.

  6. Step 6

    Remove the cinnamon stick from the chile oil and gently reheat the oil for 1 minute over medium heat, until loosened.

  7. Step 7

    To serve, pour the polenta onto a lipped platter, then scatter the mushrooms and the tomato mixture over. Top with the hot oil, thinly sliced scallions and the cilantro.

I made this tonight. I always follow the recipe the first time to experience what the chef intended. Excellent! I would not change a thing. Fast, easy, and super tasty. Thank you Yotam Ottolenghi

Start the tomatoes roasting, then add the mushrooms 5 minutes later so that both are done at the same time. Apparently tomatoes take a little longer to roast than mushrooms.

I love how the spice oil includes cinnamon along with the peppers!

This was delicious! Used a mix of blue, yellow and phoenix oyster mushrooms and some Shitake. Not quite tomato season so used a jar of Trader Joe’s slow roasted tomatoes. Subbed shallot for scallions. Served over polenta. Made the oil earlier in the day so it had time to season - such a surprise how good everything was together. I am making more of the oil just to have for other things!

Disappointed, the polenta is bland and the dish was greasy.

This dish, doubled, got rave reviews at our Passover Seder! (Not all Jewish families eat corn products during Passover, but we do). The spiced oil makes it. My cheap apartment oven couldn’t crack 430, so I had to roast the veggies for longer and finish the tomatoes on the broil setting for some nice char. I used packaged polenta, which is all I could find.
