Creamy Boursin Mushroom Pasta Skillet in 15 Minutes Step-by-step instructions

Before you start

Before starting, bring a large pot of salted water to a boil. Slice the mushrooms if not already done, mince the garlic, and chop the parsley. Have all ingredients measured and ready, as the cooking process moves quickly. Reserve a mug or measuring cup to scoop out pasta water before draining.

Instructions

Pasta and Mushrooms

1. 1Cook the Pasta
   Bring a large pot of salted water to a boil. Add the rigatoni and cook according to package instructions until al dente. Reserve 150 ml of the pasta cooking water before draining. Drain the pasta and set aside.
   Look for The pasta should be tender but still firm to the bite, and the water should be starchy and cloudy.
   Tip Don't rinse the pasta after draining—the starch helps the sauce cling.
2. 2Sear the Mushrooms
   In a large skillet, heat the olive oil and butter over high heat. Add the sliced cremini mushrooms in a single layer and cook without stirring for 2-3 minutes until deeply browned on one side. Then stir and continue cooking for another 2-3 minutes until golden brown and caramelized.
   Look for The mushrooms should be deeply golden with crispy edges and release a nutty aroma.
   Tip Don't overcrowd the pan; work in batches if needed to get a proper sear.
3. 3Add Garlic and Cheese
   Reduce the heat to medium. Add the minced garlic to the skillet and cook for 30 seconds until fragrant. Place the entire wheel of Boursin cheese in the center of the skillet and let it soften for a minute.
   Look for The garlic becomes aromatic, and the cheese begins to melt at the edges.
   Tip Stir the garlic constantly to prevent burning.

At the end of this phase, the pasta is al dente and drained, and the mushrooms are deeply golden with crispy edges.

The skillet should have a rich, nutty aroma from the browned butter and mushrooms. The garlic is fragrant but not burnt, and the Boursin cheese is just beginning to soften in the center of the pan.

Silky Sauce

4. 4Make the Sauce
   Pour the hot pasta cooking water into the skillet. Whisk the melted Boursin into the water, stirring continuously until the mixture becomes a smooth, silky sauce. Season with salt and black pepper to taste.
   Look for The sauce is glossy, creamy, and coats the back of a spoon without lumps.
   Tip Use hot water—it helps the cheese melt smoothly without clumping.
5. 5Combine Pasta and Parmesan
   Add the drained rigatoni to the skillet along with the grated parmesan. Toss everything together with tongs or a spatula until the pasta is evenly coated with the creamy sauce and the parmesan is melted.
   Look for The pasta is evenly coated and the sauce clings to every piece.
   Tip Toss gently to avoid breaking the pasta.

The sauce should be smooth, glossy, and coat the back of a spoon without any lumps. It will look pale and creamy with specks of herbs from the cheese.

The pasta is added and tossed with parmesan, creating a thick, clings-to-the-pasta consistency. The skillet is full of a creamy, garlicky aroma.

Final Toss and Serve

6. 6Finish and Serve
   Remove the skillet from the heat. Sprinkle the fresh chopped parsley over the pasta and give it one final toss. Serve immediately, twirling a forkful of pasta with a sautéed mushroom for the perfect bite.
   Look for The parsley adds a fresh green contrast to the creamy sauce.
   Tip Serve right away—the sauce thickens as it cools.

The parsley adds a fresh green color and a pop of brightness. The pasta is evenly coated, and the sauce is thick enough to hold onto the rigatoni. The dish is steaming hot and ready to serve immediately. The final texture should be creamy, not runny, with the mushrooms distributed throughout.

Common mistakes

One common mistake is overcrowding the skillet when searing the mushrooms, which causes them to steam instead of brown. Cook them in a single layer and give them space.

Another is adding the cheese before the garlic is fragrant—that can lead to a raw garlic bite. Also, avoid over-stirring the pasta once it's in the sauce; toss gently to keep the pasta intact.

How to tell it’s done

The dish is done when the pasta is al dente and the sauce is thick enough to coat the back of a spoon. The mushrooms should be deeply browned and the cheese fully melted into a smooth sauce.

Taste and adjust seasoning with salt and pepper. The pasta should be glossy and creamy, not soupy—if it seems too thick, add a splash of extra pasta water to loosen it.
