How to make this mushroom and bacon pasta gratin
- Cook the pasta: In a large pot, cook the pasta according to the package instructions. Before draining, reserve 1 cup of the pasta cooking water. Drain and set aside.
- Prepare the mushrooms: Gently wipe them clean with a cloth (no soaking — they’re not sponges), then chop into small pieces. Place in a bowl and toss with the herbs and spices.
- Cook the filling: In a large saucepan, heat the olive oil over medium heat. Add the mushrooms and bacon and cook for about 5 minutes, until the bacon slivers are lightly golden and the mushrooms have softened.
- Make the sauce: Pour in the reserved pasta water and stir, scraping up all the flavorful bits from the pan. Let it simmer briefly so the juices combine into a light sauce.
- Assemble: Transfer the drained pasta to a large casserole dish. Layer the mushroom and bacon mixture over the pasta and pour the sauce evenly on top. Gently mix to combine.
- Bake: Preheat the oven to 375°F (190°C). Sprinkle the parmesan evenly over the top and lightly mix into the upper layer. Bake for 10–15 minutes, until the cheese is melted and golden.
- Serve hot while the top is bubbly and the edges are just slightly crisp.
When in the mood for an easy meal that’s sure to satisfy, mushroom pasta gratin is the perfect dish to make. Inspired by the cheesy gratin dauphinois, this mushroom and pasta gratin is simple, easy to prepare, and it never fails to please.
Mushroom is one of the most popular and versatile culinary ingredients. You can use any types of mushrooms, white, brown, button, shiitake or cremini, portobello or even a mix of all of the above. It really depends on your personal preference.



The key is to cook the mushrooms in advance with the bacon or pancetta so that the juices of the two mix together to create a tangy base for the pasta.
Then add some sharp parmesan cheese to bring the dish to a whole another level. Whether you want to serve it by itself or as a side dish with friends and family, this is a French pasta dish that won’t fail to please!
