Ingredients
- 2pounds mixed mushrooms, such as cremini, oyster and shiitake
- 1red onion, cut into thin wedges
- 20large sage leaves, chopped
- 5 to 6sprigs thyme or 2 to 3 sprigs rosemary, leaves picked
- 4garlic cloves, smashed and peeled
- Olive oil
- Salt and pepper
- 2lemons, quartered, plus 1 more to serve
- 1pound short pasta
- 3tablespoons butter
- 1tablespoon soy sauce
- Grated Parmesan or nutritional yeast, to serve
- Handful chopped chives or parsley
Preparation
- Step 1
Heat the oven to 425 degrees.
- Step 2
Prepare the mushrooms: For clustered varieties like oyster mushrooms, simply tear them through the base to separate them; for capped mushrooms, cut in half or quarters, depending upon size. The mushrooms don’t have to be the same size.
- Step 3
Place the mushrooms, red onion, sage, thyme and garlic onto a sheet pan. Drizzle generously with olive oil and season well with salt and pepper. Arrange the lemon wedges among the mushrooms. Roast until the mushrooms have collapsed and are golden around the edges, 20 to 25 minutes.
- Step 4
Meanwhile, bring a large pot of salted water to a boil. Add the pasta and cook until al dente. Drain and reserve 1 cup of cooking water.
- Step 5
When the mushrooms and onions are ready, remove from the oven and using a fork or back of a large spoon, squash the garlic and mash it into a paste. Squeeze the roasted lemons over the mushrooms.
- Step 6
Return the pasta to the pot it was cooked in, and place on medium-low heat. Add the butter and soy sauce along with ½ cup of the starchy pasta water. Toss for 1 to 2 minutes until the butter has melted.
- Step 7
Add the mushroom mixture, making sure to scrape off any bits stuck to the pan. Toss for 2 minutes. If the pasta looks dry, add a tablespoon or two more of the reserved pasta water. Drizzle generously with olive oil, and season well with salt and pepper.
- Step 8
To serve, squeeze over more lemon juice, top with Parmesan and finish with the chives.

Before anyone asks: yes, you can substitute medium-sized sage leaves if you don't have large ones. Just use more. I just made this, as written, for dinner for my friend Keith and me. We both loved it! Heavy umami. I sent Keith off with a container of leftovers, but I suspect he's just going to give it all to his pet goat, Sir Butterscotch. He spoils that animal.
"Mash the garlic into a paste" And then do what with it? Toss with the mushrooms?
Just made this tonight. Absolutely delicious!!
Meh, not for me. Pretty expensive and not special. Aftertaste was sorta bitter. Wouldn’t make again.
I just made this for 2 and it was delicious! I had about 3 cups of mixed mushrooms (lion’s mane, oyster, etc) which I pulled apart and roasted on convect with the other ingredients for about 12 minutes (any longer and they’d have been dehydrated). I tossed a couple of handfuls of baby spinach with the cooked penne and added a bit more garlic to boost the flavour. I didn’t use the extra lemon for finishing because my roasted lemon wedges had been so juicy. This is a very versatile recipe that lends itself to all kinds of creative modifications. The idea of roasting the mushrooms and aromatics is clever and really helped to deepen the flavour! This would be wonderful made for guests, too!
@Danielle Thanks for your helpful comments
Double the garlic; roast in the skins. Remove when soft and mash in small bowl. 20 sage leaves chopped, 1/2 teaspoon thyme leaves, teaspoon chopped rosemary. 1/2 oyster and 1/2 cremini; roast until almost all liquid has evaporated and they are starting to brown. Roasted at 400 for approximately 60 minutes. 1 very large red onion. 1 large lemon roasted; pressed through sieve into sauce. 1 fresh lemon at the table.
