Method
Cook the pasta
Bring a large pan of heavily salted water to a rolling boil. Cook the rigatoni according to packet instructions until al dente โ usually 10โ12 minutes. Before draining, save a large mugful of the starchy pasta water. This is gold for getting the sauce to cling perfectly.
Brown the mushrooms
While the pasta cooks, heat a wide frying pan over a high heat until very hot. Add a tablespoon of olive oil and the sliced mushrooms in a single layer. Do not stir โ leave them untouched for 2โ3 minutes so they get deeply golden on one side. This browning gives incredible flavour. Season with salt, toss, and brown the other side.
Build the sauce
Reduce the heat to medium. Add the butter, shallot, and garlic to the mushrooms. Cook for 3 minutes, stirring, until the shallot is soft. Add the fresh thyme and cook for 30 seconds more. Pour in the white wine โ it will sizzle and steam. Let it bubble and reduce by half, about 2 minutes.
Add the cream
Pour in the double cream and stir to combine. Bring to a gentle simmer and let it reduce for 2 minutes until slightly thickened. Taste and season well with salt and plenty of black pepper.
Bring it all together
Add the drained pasta to the sauce along with half the grated Parmesan and a generous splash of the reserved pasta water. Toss everything together vigorously over the heat for 1โ2 minutes โ the sauce should become glossy and cling to every piece of pasta. Add more pasta water as needed to loosen.
Finish and serve
Squeeze over a little lemon juice, scatter with chopped parsley and the remaining Parmesan. Serve immediately in warmed bowls, with extra Parmesan on the side and plenty of black pepper.
My Monday story
Pasta on a Monday is a ritual in my house. After a long first day of the working week, sometimes all you want is something comforting, quick, and satisfying. This mushroom pasta delivers on every count.
I discovered the trick of not stirring the mushrooms โ letting them properly brown in a screaming hot pan โ from watching a chef on TV years ago, and it completely changed how I cook mushrooms. That caramelisation is where all the flavour lives.
