Mushroom Pesto Pasta

There was a Wednesday evening last spring when I had exactly twenty-seven minutes before my neighbor was supposed to come over for dinner. I pulled out a box of penne, a container of pesto from the back of the fridge, and a bag of mushrooms that had been sitting there since Sunday. What came together in that skillet turned into something I now make at least twice a month. The mushrooms get golden and almost meaty, the pesto melts into the cream, and suddenly you have a dish that tastes like you spent an hour on it.

The first time I made this for my sister, she stopped mid-bite and asked if I'd added truffle oil. I hadn't, but the way the garlic clings to the mushrooms and mingles with the basil does something almost luxurious. She went back for seconds before I'd even finished my first plate. Now every time she visits, she asks if we're having that mushroom pasta, and I know exactly what she means.

Ingredients

• Penne or fettuccine: Penne holds the creamy sauce in its ridges, while fettuccine gives you long, silky ribbons that twirl beautifully around your fork.
• Cremini or button mushrooms: Cremini have a deeper, earthier flavor, but button mushrooms work just as well and turn golden and tender when you give them enough time in the pan.
• Olive oil and butter: Using both gives you the fruitiness of olive oil and the rich, nutty flavor that only butter can bring to sautéed mushrooms.
• Garlic: Fresh garlic is non-negotiable here, it blooms in the hot oil and fills your kitchen with the kind of smell that makes people wander in asking whats for dinner.
• Basil pesto: Whether you make your own or use a good jar from the store, pesto is the heart of this dish, bringing brightness and herby depth to every bite.
• Heavy cream: This is what turns the pesto into a sauce that coats the pasta instead of just sitting on top, making everything luscious and cohesive.
• Parmesan cheese: Freshly grated Parmesan melts into the sauce and adds a salty, nutty finish that ties everything together.
• Fresh basil for garnish: A few torn leaves on top add a pop of color and a hint of freshness that makes the whole plate look alive.

Instructions

Boil the pasta:

Bring a big pot of salted water to a rolling boil and cook your pasta until its just al dente, with a slight bite in the center. Before you drain it, scoop out half a cup of that starchy pasta water, it will be your secret weapon for making the sauce cling.

Sauté the mushrooms:

Heat the olive oil and butter in a large skillet over medium heat until the butter foams, then add the sliced mushrooms in a single layer if you can. Let them sit undisturbed for a few minutes so they get golden and caramelized, then stir and cook until theyre tender and fragrant.

Add the garlic:

Toss in the minced garlic and stir it around for about a minute, just until it smells incredible and starts to turn golden. Be careful not to let it burn or it will taste bitter.

Make the creamy pesto sauce:

Lower the heat and stir in the pesto and heavy cream, mixing until everything is smooth and combined. Add the grated Parmesan and keep stirring until it melts into the sauce and everything looks glossy.

Toss the pasta:

Add the drained pasta to the skillet and toss it all together, adding splashes of that reserved pasta water until the sauce reaches a creamy, silky consistency that coats every piece. Season with salt and black pepper, taste it, and adjust as needed.

One night I made this after a long day and ate it straight out of the skillet, standing at the stove with a fork. My partner walked in, grabbed another fork, and joined me without saying a word. We finished the whole pan like that, and it became one of those quiet, unplanned moments that somehow felt more special than any formal dinner.

Choosing Your Mushrooms

Cremini mushrooms are my go-to because they have a firmer texture and a deeper, almost nutty flavor that stands up to the richness of the cream. Button mushrooms are milder and a little more delicate, but they work beautifully if thats what you have. I once tried a mix of cremini and shiitake, and the result was earthy and complex, almost like the pasta had been simmering for hours. Whatever you use, make sure theyre sliced evenly so they all cook at the same rate.

Making It Your Own

This recipe is incredibly flexible once you understand the base. Ive stirred in handfuls of baby spinach right at the end and watched it wilt into the sauce, adding color and a slight bitterness that balances the cream. Sun-dried tomatoes are another favorite, their sweet-tart chewiness cuts through the richness in the best way. If you want a little heat, a pinch of red pepper flakes in with the garlic will give the whole dish a gentle warmth that lingers.

Storing and Reheating

Leftovers keep well in the fridge for up to three days, though the sauce will thicken as it cools. When you reheat it, add a splash of cream, milk, or even pasta water to loosen it back up, and warm it gently in a skillet over low heat. The pasta will soak up more of the sauce as it sits, so it might not look as saucy the next day, but the flavor will be even more concentrated.

• Store in an airtight container to keep the pasta from drying out.
• Reheat on the stovetop rather than the microwave for the best texture.
• If the sauce breaks or looks oily, a little splash of water and a good stir will bring it back together.

This pasta has become my answer to nearly every occasion: too tired to think, need to impress someone, craving comfort, or just want something that tastes like care without much effort. It works every single time.

Recipe FAQs

→ Can I make this dish vegan?

Yes, easily! Substitute the heavy cream with plant-based cream, use vegan pesto, and replace Parmesan with nutritional yeast. The flavor profile remains rich and satisfying while maintaining the dish's creamy texture.

→ What type of mushrooms work best?

Cremini and button mushrooms are ideal for their tender texture and mild flavor. However, you can also use portobellos for a deeper, earthier taste, or a mixture of wild mushrooms for added complexity and visual appeal.

→ How do I achieve the perfect pasta consistency?

Cook the pasta one minute before the package instructions suggest to keep it slightly firmer. Use reserved pasta water to adjust the sauce consistency—add a little at a time while tossing until the sauce coats the pasta beautifully without becoming runny.

→ Can I use homemade pesto instead of store-bought?

Absolutely! Homemade pesto adds wonderful freshness and depth. Blend fresh basil, garlic, pine nuts, Parmesan, and olive oil. Use the same amount as store-bought pesto, though you may need to adjust salt and seasonings based on your blend.

→ What wine pairs well with this dish?

Crisp white wines work beautifully—Pinot Grigio and Sauvignon Blanc are excellent choices. Their acidity cuts through the richness of the cream sauce and complements the fresh basil flavors while enhancing the earthy mushroom notes.

→ How can I add more vegetables to this dish?

Baby spinach, sun-dried tomatoes, cherry tomatoes, or roasted zucchini all work wonderfully. Add spinach to the sauce at the end to gently wilt, or toss pre-cooked vegetables with the pasta for added nutrition and color.
